Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy(LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time. However, this technique may have some advantages for avoiding unnecessary extended resection in patients with an appendiceal mass. Nonoperative management of AA may be tolerated only in children. Postoperative complications increase according to the patient's factors, and temporal avoidance of emergent general anesthesia may be beneficial for high-risk patients. The surgeon's skill and cooperation of the hospital are important for successful LA. Delaying appendectomy for less than 24 h from diagnosis is safe. Additionally, a semi-elective manner(i.e., LA within 24 h after onset of symptoms) may be paradoxically acceptable, according to the factors of the patient, physician, and institution. Prompt LA is mandatory for AA. Fortunately, the Japanese government uses a universal health insurance system, which covers LA.展开更多

METHODS: Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS: There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients (1.5%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 d vs 3.1 d, P = 0.04), and lower incidence of wound infection (5.3% vs 12.8%, P = 0.03). However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy (5.3% vs 2.1%, P = 0.002). The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 € in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is as safe and effi cient as open appendectomy, provided surgical experience and equipment are available.展开更多

The overall mortality rate for open appendectomy (OA) is around 0.3% and morbidity is about 11%. Objective: To compare laparoscopic vs open appendectomy with regard to postoperative pain and nausea, operative results, perioperative and postoperative complications, hospital admission. Methods: This prospective comparative study is performed in the Department of Surgery, North West Aramed Forced Hospital, Tabuk, Kingdom of Saudi Arabia. All patients between 13 and 60 years of age admitted through the accident and emergency (A&E) department with a clinical diagnosis of acute appendicitis and those who completed follow-up are included in the study. All those patients in whom a clinical diagnosis of acute appendicitis was not established or have a palpable mass in the right lower quadrant, suggesting an appendiceal abscess and those who does not give consent are excluded from the study. We reviewed the medical records of all patients who underwent a laparoscopic and open appendectomy in King Salman Armed Forces Hospital, Saudi Arabia from 1/1/2012 to 31/12/2015. Result: A total of 502 patients underwent Appendectomy at King Salman Armed Forces Hospital from 1/1/2012 till 31/12/2015. Of these, 203 were male (40.4%) and 299 were female (59.6%). The mean age was 18 years. Alvarado Score more than 7 in 93% of patients diagnosed with appendicitis. Comorbidities included diabetes 21 (5.56%) and hypertension 7 (1.39%). The mean Body Mass Index (BMI) was 20 kg/m<sup>2</sup>. 328 patients (65.3%) underwent Open Appendectomy (OA). None of Laproscopic appendectomy(LA) had a conversion. The mean operative time was 76 minutes (44 minutes and 50 minutes for OA and LA, respectively). Mean hospital stay in OA 2 days and one day LA. Eight cases (1.6%) developed seroma (6 cases in OA and 2 cases in LA with rates of 1.2% and 0.4% respectively). Nine patients (1.6%) had wound infection, 8 in OA and one in LA with rate of 1.5% and 0.2% respectively). Four patients (0.8%) develop the hematoma (3 cases in OA and one case in LA with rates of 0.6% and 0.2% respectively). Seven cases of reported appendectomy develop the pelvic abscess (1.4%) (5 cases in OA and 2 cases in LA with rates of 1% and 0.4% respectively). Conclusion: Alvarado Score carries high significance in the diagnosis of acute appendicitis. Laparoscopic appendectomy has improved diagnostic accuracy along with advantages in terms of fewer seroma, hematoma, wound infections, faster recovery, and earlier retention to normal activity but longer operative time.展开更多

METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases.展开更多

The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen. There was no nausea or vomiting and bowel movements were normal. She lost 10 kg during the 3 mo before presentation. The patient had undergone an appendectomy 12 years previously. Physical examination revealed a tender mass, 10 cm in diameter, under the appendectomy scar. The preoperative laboratory findings, tumor markers and plain abdominal radiographs were normal. Multi-slice computed tomography scanning showed an inhomo-genous abdominal mass with minimal vascularization in the right lower abdomen 8.6cm×8cm×9 cm in size which communicated with the abdominal wall. The abdominal wall was thickened, weak and bulging. The abdominal wall mass did not communicate with the cecum or the ascending colon. Complete excision of the abdominal wall mass was performed via median laparotomy. Histopathological examination revealed a granuloma with a central abscess. This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options.展开更多

It is hypothesized that chewing gum reduces postoperative ileus by improving early recovery of gastrointestinal function. This study aimed to explore whether chewing gum after appendectomy accelerates the recovery of gastrointestinal function.Methods: Randomized control trial was used in this study. This study was conducted in the General Surgery Department at Zagazig University Hospital. A total of 240 patients undergoing appendectomy were involved in this study; they were divided into the chewing sugar-free gum group(120) and the control group(120). Two tools were utilized in this study. Tool I: Structured Interviewing Schedule: part 1: assessment of personnel characteristics. Part 2: assessment of anthropometric measurements of the studied subjects as well as pre-and intraoperative indicators of them. Tool II: postoperative assessment sheet: assessed postoperative parameters of the intestinal function, occurrence of postoperative ileus, and related symptoms were assessed among studied participants.Results: There were highly significant statistical differences in the time of resumption of gastrointestinal functions and postoperative ileus symptoms between the two groups(P<0.001), which was significantly shorter in the chewing gum group compared to the control group.Conclusions: The use of chewing gum is a useful and cheap method that can be employed to cut down the time to recover and accelerate normalization of gastrointestinal function. Chewing sugar-free gum after abdominal surgery is recommended to be added to the protocol of nursing care in the surgery units as well as its involvement in the nursing curriculum.展开更多

Intussusception could progress to lifethreatening complications if left untreated or could delay chemotherapy if inappropriate surgical management is used. We report a 31-year-old man diagnosed with human immunodeficiency virus who was being treated with antiretroviral therapy. He presented with nausea, vomiting, poor appetite, and intermittent, cramping abdominal pain for over 1 wk. Abdominal computed tomography revealed a well-defined homogeneous mass in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception, which was suspected to be caused by a lymphoma. The intussusception was successfully laparoscopically reduced, and the tumor involvement of the appendix was confirmedby appendectomy with intraoperative frozen section. Systemic chemotherapy was immediately initiated after surgery without the need for bowel resection.展开更多

On physical examination, a vague mass was palpable in the right lumbar region. His routine laboratory tests were normal. Ultrasonography showed a hypoechoic lesion in the right lumbar region anterior to the right kidney with internal echoes and fluid components. Abdominal contrast-enhanced computed tomography （CECT） showed a well-defined hypodense cystic mass lesion lateral to the ascending colon/caecum, not communicating with the lumen of colon/caecum. After complete open excision of the cystic mass lesion, gross pathologic examination revealed a turgid cystic dilatation of appendiceal remnant filled with the mucinous material. On histopathological examination, mucinous cyst adenoma of appendix was confirmed. We report this rare unusual late complication of mucocele formation in the distal viable appendiceal remnant, which was leftover following incomplete retrograde appendectomy. This unusual complication is not described in the literature and we report it in order to highlight the fact that a high index of clinical and radiological suspicion is essential for the diagnosis of mucocele arising from a distal viable appendiceal remnant in a patient who has already undergone appendectomy presenting with recurrent abdominal pain.展开更多

A 47-year-old woman visited the surgical department, since she had a gradually growing and painful tumor both in an appendectomy scar and at an umbilical site. She underwent appendectomy at age 18 years, and noticed the tumor at age 22 years. Partial tumor resection was performed in that department, and the pathology revealed endometrioid adenocarcinoma. She was referred to our department for radical therapy. Tumors in the both sites were dissected together with some swelling lymph nodes in our department. A pathological diagnosis of the tumor in the umbilical site showed only benign endometriosis. In contrast, the tumor in the appendectomy scar showed benign endometriosis, atypical endometriosis and well differentiated endometrioid adenocarcinoma. Resected lymph nodes also contained endometrioid adenocarcinoma, and were diagnosed as metastases. It was concluded that the endometrioid adenocarcinoma in the tumor of the appendectomy scar was a malignant transformation arising from abdominal wall endometriosis from the pathological findings. Since the operation, adjuvant and maintenance chemotherapy with paclitaxel and carboplatin had been administered for 3 years. She is free of disease 3.5 years after the operation.展开更多
文摘BACKGROUND Retrocecal appendicitis,the most common anatomical type,presents diagnostic and surgical challenges.Single-port laparoscopic appendectomy(SPLA)has been proposed as an alternative to multi-port laparoscopic appendectomy(MPLA)with advancements in minimally invasive surgery.However,few studies have compared the perioperative outcomes between the SPLA and MPLA for retrocecal appendicitis.AIM To compare the efficacy and safety between the SPLA and MPLA in treating retrocecal appendicitis,focusing on perioperative outcomes.METHODS This retrospective study analyzed data from 1041 patients who underwent SPLA or MPLA at Konyang University Hospital between October 2011 and February 2023.Propensity score matching(PSM)was used to minimize selection bias,resulting in 235 patients in each group.Additionally,non-inferiority tests,post-hoc analysis,and multivariable regression analysis were performed to validate the results and assess factors affecting postoperative outcomes.RESULTS After PSM,SPLA showed shorter operation time(43.8±15.8 minutes vs 51.6±18.7 minutes;P<0.001)and lower estimated blood loss(EBL,6.5±7.8 mL vs 8.6±8.3 mL;P<0.001)than MPLA.No significant differences were observed in complications,pain scores,or length of hospital stay.SPLA was not inferior to MPLA in the main outcomes,except for the complication rate,where statistical power was insufficient.Multivariable regression confirmed SPLA as an independent factor for operation time and EBL.CONCLUSION SPLA is more feasible than MPLA for retrocecal appendicitis,offering advantages in operation time and estimated blood loss.This study supports SPLA as a viable alternative that enhances postoperative recovery.

文摘BACKGROUND Single-port laparoscopic appendectomy is an advanced minimally invasive surgery that involves the use of upgraded instruments and equipment.We previously modified single-port laparoscopic appendectomy with needle-type grasping forceps(mSLAN)for patients with simple appendicitis,but the feasibility and safety of our modified procedure need further evaluation in a highquality clinical study.AIM To compare the short-term clinical outcomes of mSLAN with those of conventional three-port laparoscopic appendectomy(CLA)for patients with acute uncomplicated appendicitis.METHODS This single-center,single-blind,prospective,randomized controlled trial included patients who underwent emergency laparoscopic appendectomy for acute uncomplicated appendicitis at our center between April 2024 and August 2024.Patients were randomly divided into the mSLAN group or the CLA group via computergenerated randomization.The primary endpoint was the 24-hour postoperative visual analog scale(VAS)score,and the secondary endpoints included the operative time,24-hour postoperative inflammatory response biomarkers(including white blood cells,the neutrophil ratio,interleukin-6,and C-reactive protein),time to first postoperative exhaust,time to first out-of-bed activity,postoperative length of hospital stay,cost of hospitalization,and incidence of postoperative complications.RESULTS A total of 72 patients were enrolled and randomly divided into 2 groups:The mSLAN group(n=36)and the CLA group(n=36).The 24-hour VAS scores,24-hour postoperative inflammatory response marker levels,first postoperative exhaust times,first out-of-bed activity times,postoperative lengths of hospital stay,operative times,or hospitalization costs did not significantly differ between the two groups.No postoperative complications,including incision infection or hernia,abdominal abscess or intestinal obstruction,were observed during the 1-month postoperative follow-up in either group.CONCLUSION Compared with the CLA protocol,the mSLAN protocol for acute uncomplicated appendicitis yielded comparable short-term clinical outcomes,with a similar operative time and better cosmetic outcomes,indicating its potential for clinical application and superiority for patients with high cosmetic requirements.Further research is needed to evaluate the long-term outcomes.
文摘BACKGROUND Laparoscopic appendectomy(LA)is the standard treatment for acute appendicitis in children,offering reduced postoperative pain and quicker recovery compared to open surgery.A critical aspect of LA is the secure closure of the appendiceal stump to avoid complications such as leakage and abscess formation.Various closure techniques are employed,including endoloops(ELs),staplers,clips,and energy devices;however,the optimal method remains unclear due to inconsistent evidence.AIM To systematically evaluate and rank the effectiveness and safety of different appendiceal stump closure techniques used in pediatric LA.By assessing outcomes such as postoperative complications,operative time,and length of hospital stay,this analysis seeks to provide evidence-based guidance to clarify clinical decision-making and optimize patient care.METHODS This systematic review and network meta-analysis,conducted according to PRISMA and Cochrane guidelines,compared the effectiveness and safety of stump closure methods in pediatric LA.Databases searched included PubMed,Cochrane Central,Web of Science,and Scopus up to May 1,2025.Eligible studies included both randomized and non-randomized designs reporting surgical outcomes in pediatric patients.Two reviewers independently extracted data and assessed the risk of bias using the Newcastle-Ottawa Scale.A frequentist network meta-analysis with a random-effects model was conducted using R software to evaluate total complications(primary outcome),as well as operative time and hospital stay(secondary outcomes).P-scores were used to rank the effectiveness of treatments.RESULTS Fourteen studies comprising over 50000 pediatric patients were included in the network meta-analysis comparing appendiceal stump closure techniques in LA.No significant differences in total postoperative complications or hospital stay were observed among techniques,including EL,endostapler,polymer clip,LigaSure,harmonic scalpel(HS),and sutures.HS showed a statistically significant reduction in operative time compared to EL(mean difference:-13.5 minutes),while other methods did not demonstrate significant time savings.No technique was associated with a statistically significant increase or decrease in postoperative complications or length of stay.Publication bias was minimal,and the methodological quality of included studies was moderate to good.CONCLUSION While all closure techniques show similar safety profiles,HS offers shorter operating times.These findings support tailoring stump closure method selection based on operative efficiency and resource availability.
文摘BACKGROUND Appendicitis is a common acute abdominal pain disorder.Laparoscopic appendectomy,a commonly used modality,is associated with less trauma and faster recovery than traditional open appendectomy.However,postoperative recovery remains an important issue that affects rehabilitation quality and surgical results.AIM To explore the effects of rapid rehabilitation and surgical nursing care on gastrointestinal function recovery and sleep quality among patients undergoing laparoscopic appendectomy.METHODS A total of 120 patients who underwent laparoscopic appendectomy at our hospital between January 2019 and March 2024 and for whom complete clinical data were available were selected.Patients were randomly assigned to two groups(n=60 each)using the random number table method.The control group received routine nursing care,while the experimental group received rapid rehabilitation surgical nursing care;all patients continued to receive nursing care until discharge.The recovery of gastrointestinal function,length of hospital stay,complications,Pittsburgh sleep quality index,and nursing satisfaction were compared between groups.RESULTS Following the implementation of effective nursing measures,the times to bowel sound recovery,first exhaust,first defecation,and first feeding were notably shorter in the study vs control group(P<0.05).Additionally,the duration of the first postoperative activity and the length of hospital stay were significantly shorter in the study vs control group(P<0.05).Furthermore,the study group exhibited better sleep quality than the control group(P<0.05).The postoperative complication rate was significantly lower and the nursing satisfaction rate significantly higher in the study vs control group(P<0.05).CONCLUSION Rapid rehabilitation surgical nursing interventions provided to patients after laparoscopic appendectomy can accelerate their postoperative recovery,reduce the occurrence of complications,and improve their sleep quality and nursing satisfaction.
文摘BACKGROUND Acute appendicitis(AP)is a frequently encountered surgical emergency,and appendectomy is conventionally regarded as the predominant treatment moda-lity.Nevertheless,the therapeutic efficacy of this surgical approach remains to be improved.Thus,the exploration and implementation of surgical refinements are necessary.AIM To elucidate the therapeutic effectiveness and influencing factors of laparoscopic appendectomy(LA)with mesoappendix dissection in the treatment of AP.METHODS First,150 patients with AP who visited Shangrao Municipal Hospital between January 2022 and June 2024 were enrolled in this study.Among them,72 patients were assigned to the control group to receive conventional LA,whereas 78 cases were included in the observation group for LA with mesoappendix dissection.Subsequently,indicators such as therapeutic effectiveness,surgical indices(ope-ration time,intraoperative blood loss,and hospital stay),postoperative recovery indices(time to ambulation,gastrointestinal function recovery time,and time to food intake),incidence of adverse events(postoperative bleeding,pelvic infection,puncture site infection,and ileus),and serum inflammatory factors[tumor necro-sis factor(TNF)-α,interleukin(IL)-6,and C-reactive protein(CRP)]were collected and comparatively analyzed,and the influencing factors of therapeutic effecti-veness in patients with AP were analyzed.RESULTS Compared with the control group,the observation group had higher clinical the-rapeutic effectiveness,less operation time,intraoperative blood loss,and hospital stay;shorter time to ambulation,gastrointestinal function recovery,and food intake;and a lower total incidence of adverse events,and this difference is statistically significant.In addition,the expression levels of various serum inflammatory factors in the observation group were significantly reduced postoperatively,which were markedly lower than those in the control group.Moreover,sex,age,body mass index,time from acute onset to admission,family medical history,preoperative TNF-α,preoperative IL-6,preoperative CRP,and treatment modality were identified to be not independent factors affecting the therapeutic effectiveness of LA with mesoappendix dissection in patients with AP.CONCLUSION Overall,LA with mesoappendix dissection has a remarkable curative effect in treating patients with AP,which is worthy of clinical promotion.
文摘Acute appendicitis(AA) develops in a progressive and irreversible manner, even if the clinical course of AA can be temporarily modified by intentional medications. Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy(LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time. However, this technique may have some advantages for avoiding unnecessary extended resection in patients with an appendiceal mass. Nonoperative management of AA may be tolerated only in children. Postoperative complications increase according to the patient's factors, and temporal avoidance of emergent general anesthesia may be beneficial for high-risk patients. The surgeon's skill and cooperation of the hospital are important for successful LA. Delaying appendectomy for less than 24 h from diagnosis is safe. Additionally, a semi-elective manner(i.e., LA within 24 h after onset of symptoms) may be paradoxically acceptable, according to the factors of the patient, physician, and institution. Prompt LA is mandatory for AA. Fortunately, the Japanese government uses a universal health insurance system, which covers LA.
文摘AIM: To compare the outcome of laparoscopic versus open appendectomy. METHODS: Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS: There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients (1.5%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 d vs 3.1 d, P = 0.04), and lower incidence of wound infection (5.3% vs 12.8%, P = 0.03). However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy (5.3% vs 2.1%, P = 0.002). The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 € in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is as safe and effi cient as open appendectomy, provided surgical experience and equipment are available.
文摘Background: Appendicitis is one of the most common surgical emergencies requiring an appendectomy, with a life-time risk of 6%. The overall mortality rate for open appendectomy (OA) is around 0.3% and morbidity is about 11%. Objective: To compare laparoscopic vs open appendectomy with regard to postoperative pain and nausea, operative results, perioperative and postoperative complications, hospital admission. Methods: This prospective comparative study is performed in the Department of Surgery, North West Aramed Forced Hospital, Tabuk, Kingdom of Saudi Arabia. All patients between 13 and 60 years of age admitted through the accident and emergency (A&E) department with a clinical diagnosis of acute appendicitis and those who completed follow-up are included in the study. All those patients in whom a clinical diagnosis of acute appendicitis was not established or have a palpable mass in the right lower quadrant, suggesting an appendiceal abscess and those who does not give consent are excluded from the study. We reviewed the medical records of all patients who underwent a laparoscopic and open appendectomy in King Salman Armed Forces Hospital, Saudi Arabia from 1/1/2012 to 31/12/2015. Result: A total of 502 patients underwent Appendectomy at King Salman Armed Forces Hospital from 1/1/2012 till 31/12/2015. Of these, 203 were male (40.4%) and 299 were female (59.6%). The mean age was 18 years. Alvarado Score more than 7 in 93% of patients diagnosed with appendicitis. Comorbidities included diabetes 21 (5.56%) and hypertension 7 (1.39%). The mean Body Mass Index (BMI) was 20 kg/m<sup>2</sup>. 328 patients (65.3%) underwent Open Appendectomy (OA). None of Laproscopic appendectomy(LA) had a conversion. The mean operative time was 76 minutes (44 minutes and 50 minutes for OA and LA, respectively). Mean hospital stay in OA 2 days and one day LA. Eight cases (1.6%) developed seroma (6 cases in OA and 2 cases in LA with rates of 1.2% and 0.4% respectively). Nine patients (1.6%) had wound infection, 8 in OA and one in LA with rate of 1.5% and 0.2% respectively). Four patients (0.8%) develop the hematoma (3 cases in OA and one case in LA with rates of 0.6% and 0.2% respectively). Seven cases of reported appendectomy develop the pelvic abscess (1.4%) (5 cases in OA and 2 cases in LA with rates of 1% and 0.4% respectively). Conclusion: Alvarado Score carries high significance in the diagnosis of acute appendicitis. Laparoscopic appendectomy has improved diagnostic accuracy along with advantages in terms of fewer seroma, hematoma, wound infections, faster recovery, and earlier retention to normal activity but longer operative time.
文摘AIM: To investigate the prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis. METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases.
文摘AIM: To assess the differences in clinical benefits and disadvantages of single-incision laparoscopic appendectomy(SILA) and conventional laparoscopic appendectomy(CLA).METHODS: The Cochrane Library,MEDLINE,Embase,Science Citation Index Expanded,and Chinese Biomedical Literature Database were electronically searched up through January 2013 to identify randomized controlled trails(RCTs) comparing SILA with CLA.Data was extracted from eligible studies to evaluate the pooled outcome effects for the total of 1068 patients.The meta-analysis was performed using Review Manager 5.2.0.For dichotomous data and continuous data,the risk ratio(RR) and the mean difference(MD) were calculated,respectively,with 95%CI for both.For continuous outcomes with different measurement scales in different RCTs,the standardized mean difference(SMD) was calculated with 95%CI.Sensitivity and subgroup analyses were performed when necessary.RESULTS: Six RCTs were identified that compared SILA(n = 535) with CLA(n = 533).Five RCTs had a high risk of bias and one RCT had a low risk of bias.SILA was associated with longer operative time(MD = 5.68,95%CI: 3.91-7.46,P < 0.00001),higher conversion rate(RR = 5.14,95%CI: 1.25-21.10,P = 0.03) and better cosmetic satisfaction score(MD = 0.52,95%CI: 0.30-0.73,P < 0.00001) compared with CLA.No significant differences were found for total complications(RR = 1.15,95%CI: 0.76-1.75,P = 0.51),drain insertion(RR = 0.72,95%CI: 0.41-1.25,P = 0.24),or length of hospital stay(SMD = 0.04,95%CI:-0.08-0.16,P = 0.57).Because there was not enough data among the analyzed RCTs,postoperative pain was not calculated.CONCLUSION: The benefit of SILA is cosmetic satisfaction,while the disadvantages of SILA are longer operative time and higher conversion rate.
文摘Advances in understanding the interaction between the human immune system and the microbiome have led to an improved understanding of the function of the vermiform appendix as a safe-house for beneficial bacteria in the colon.These advances have been made despite long standing clinical observations that the appendectomy is a safe and effective procedure.However,more recent clinical data show that an appendectomy puts patients at increased risk for recurrent Clostridium difficile(C.difficile)-associated colitis,and probably other diseases associated with an altered microbiome.At the same time,appendectomy does not apparently put patients at risk for an initial onset of C.difficile-associated colitis.These clinical observations point toward the idea that the vermiform appendix might not effectively protect the microbiome in the face of broad spectrum antibiotics,the use of which precedes the initial onset of C.difficile-associated colitis.Further,these observations point to the idea that historically important threats to the microbiome such as infectious gastrointestinal pathogens have been supplanted by other threats,particularly the use of broad spectrum antibiotics.
文摘AIM: To examine if fulminant Clostridium difficile infections(CDI) resulting in colectomy was associated with a prior appendectomy and whether any association affected the severity of the disease.METHODS: A retrospective chart review was performed on patients who underwent colectomy for CDI between 2001 and 2011.The appendectomy rate was calculated based on the absence of an appendix on the surgical pathology report.This was compared to an established lifetime risk of appendectomy in the general population.A chart review was performed for mortality and traditional markers of CDI disease severity.Fisher’s exact test was used to calculate the likelihood of association between prior appendectomy,mortality,and clinical markers of severity of infection.RESULTS: Fifty-five specimens were identified with pseudomembranous colitis consistent with CDI.All patients had a clinical history consistent with CDI and 45 of 55(81.8%) specimens also had microbiological confirmation of CDI.Appendectomy was observed in 24 of 55 specimens(0.436,99%CI: 0.280-0.606).This was compared to the lifetime incidence of appendectomy of 17.6%.The rate of appendectomy in our sample was significantly higher than would be expected in the general population(43.6% vs 17.6%,P 【 0.01).Disease severity did not differ based on presence or absence of an appendix and no association was detected between prior appendectomy and mortality(OR = 0.588,95%CI: 0.174-1.970).CONCLUSION: The rate of appendectomy in the patients whose CDI led to colectomy,was significantly higher than the calculated lifetime risk,suggesting an association of appendectomy and severe CDI resulting in colectomy.Larger prospective studies are needed to assess any potential causal relationships affecting fulminant CDI.
文摘Most complications after appendectomy occur within ten days; however, we report the unusual case of a suture granuloma 12 years after open appendectomy. The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen. There was no nausea or vomiting and bowel movements were normal. She lost 10 kg during the 3 mo before presentation. The patient had undergone an appendectomy 12 years previously. Physical examination revealed a tender mass, 10 cm in diameter, under the appendectomy scar. The preoperative laboratory findings, tumor markers and plain abdominal radiographs were normal. Multi-slice computed tomography scanning showed an inhomo-genous abdominal mass with minimal vascularization in the right lower abdomen 8.6cm×8cm×9 cm in size which communicated with the abdominal wall. The abdominal wall was thickened, weak and bulging. The abdominal wall mass did not communicate with the cecum or the ascending colon. Complete excision of the abdominal wall mass was performed via median laparotomy. Histopathological examination revealed a granuloma with a central abscess. This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options.
文摘Objective: Ileus usually occurs after abdominal surgery and is allied with complication and delays recovery. It is hypothesized that chewing gum reduces postoperative ileus by improving early recovery of gastrointestinal function. This study aimed to explore whether chewing gum after appendectomy accelerates the recovery of gastrointestinal function.Methods: Randomized control trial was used in this study. This study was conducted in the General Surgery Department at Zagazig University Hospital. A total of 240 patients undergoing appendectomy were involved in this study; they were divided into the chewing sugar-free gum group(120) and the control group(120). Two tools were utilized in this study. Tool I: Structured Interviewing Schedule: part 1: assessment of personnel characteristics. Part 2: assessment of anthropometric measurements of the studied subjects as well as pre-and intraoperative indicators of them. Tool II: postoperative assessment sheet: assessed postoperative parameters of the intestinal function, occurrence of postoperative ileus, and related symptoms were assessed among studied participants.Results: There were highly significant statistical differences in the time of resumption of gastrointestinal functions and postoperative ileus symptoms between the two groups(P<0.001), which was significantly shorter in the chewing gum group compared to the control group.Conclusions: The use of chewing gum is a useful and cheap method that can be employed to cut down the time to recover and accelerate normalization of gastrointestinal function. Chewing sugar-free gum after abdominal surgery is recommended to be added to the protocol of nursing care in the surgery units as well as its involvement in the nursing curriculum.

文摘Although primary gastrointestinal lymphoma is a rare malignancy, it can cause an intussusception in adults and can be a clinically challenging condition to manage. Intussusception could progress to lifethreatening complications if left untreated or could delay chemotherapy if inappropriate surgical management is used. We report a 31-year-old man diagnosed with human immunodeficiency virus who was being treated with antiretroviral therapy. He presented with nausea, vomiting, poor appetite, and intermittent, cramping abdominal pain for over 1 wk. Abdominal computed tomography revealed a well-defined homogeneous mass in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception, which was suspected to be caused by a lymphoma. The intussusception was successfully laparoscopically reduced, and the tumor involvement of the appendix was confirmedby appendectomy with intraoperative frozen section. Systemic chemotherapy was immediately initiated after surgery without the need for bowel resection.

文摘AIM:To investigate perception of natural orifice transluminal endoscopic surgery(NOTES)as a potential technique for appendectomy.METHODS:One hundred patients undergoing endoscopy and 100 physicians were given a questionnaire describing in detail the techniques of NOTES and laparoscopic appendectomy.They were asked about the reasons for their preference,choice of orifice,and extent of complication risk they were willing to accept.RESULTS:Fifty patients(50%)and only 21 physicians(21%)preferred NOTES(P<0.001).Patients had previously heard of NOTES less frequently(7%vs73%,P<0.001)and had undergone endoscopy more frequently(88%vs 36%,P<0.001)than physicians.Absence of hernia was the most common reason for NOTES preference in physicians(80%vs 44%,P= 0.003),whereas reduced pain was the most common reason in patients(66%vs 52%).Physicians were more likely to refuse NOTES as a novel and unsure technique(P<0.001)and having an increased risk of infection(P<0.001).The preferred access site in both groups was colon followed by stomach,with vagina being rarely preferred.In multivariable modeling,those with high-school education[odds ratio(OR):2.68,95% confidence interval(CI):1.23-5.83]and prior colonoscopy(OR:2.10,95%CI:1.05-4.19)were more likely to prefer NOTES over laparoscopic appendectomy.There was a steep decline in NOTES preference with increased rate of procedural complications.Male patients were more likely to consent to their wives vaginal NOTES appendectomy than male physicians(P=0.02).CONCLUSION:The preference of NOTES for appendectomy was greater in patients than physicians and was related to reduced pain and absence of hernia rather than lack of scarring.
文摘A 67-year old man was presented with a 6-mo history of recurrent right lower quadrant abdominal pain. On physical examination, a vague mass was palpable in the right lumbar region. His routine laboratory tests were normal. Ultrasonography showed a hypoechoic lesion in the right lumbar region anterior to the right kidney with internal echoes and fluid components. Abdominal contrast-enhanced computed tomography （CECT） showed a well-defined hypodense cystic mass lesion lateral to the ascending colon/caecum, not communicating with the lumen of colon/caecum. After complete open excision of the cystic mass lesion, gross pathologic examination revealed a turgid cystic dilatation of appendiceal remnant filled with the mucinous material. On histopathological examination, mucinous cyst adenoma of appendix was confirmed. We report this rare unusual late complication of mucocele formation in the distal viable appendiceal remnant, which was leftover following incomplete retrograde appendectomy. This unusual complication is not described in the literature and we report it in order to highlight the fact that a high index of clinical and radiological suspicion is essential for the diagnosis of mucocele arising from a distal viable appendiceal remnant in a patient who has already undergone appendectomy presenting with recurrent abdominal pain.
文摘We report a very rare case of endometrioid adenocarcinoma arising from abdominal wall endometriosis in the appendectomy scar. A 47-year-old woman visited the surgical department, since she had a gradually growing and painful tumor both in an appendectomy scar and at an umbilical site. She underwent appendectomy at age 18 years, and noticed the tumor at age 22 years. Partial tumor resection was performed in that department, and the pathology revealed endometrioid adenocarcinoma. She was referred to our department for radical therapy. Tumors in the both sites were dissected together with some swelling lymph nodes in our department. A pathological diagnosis of the tumor in the umbilical site showed only benign endometriosis. In contrast, the tumor in the appendectomy scar showed benign endometriosis, atypical endometriosis and well differentiated endometrioid adenocarcinoma. Resected lymph nodes also contained endometrioid adenocarcinoma, and were diagnosed as metastases. It was concluded that the endometrioid adenocarcinoma in the tumor of the appendectomy scar was a malignant transformation arising from abdominal wall endometriosis from the pathological findings. Since the operation, adjuvant and maintenance chemotherapy with paclitaxel and carboplatin had been administered for 3 years. She is free of disease 3.5 years after the operation.
