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

Although magnetic resonance imaging(MRI) is the most accurate modality to diagnose acute appendicitis in pregnant patients, it is often used as a last resort because of high cost and long scan time. We performed this study to analyze differential diagnoses of appendix MRI and to investigate if there are any blood tests that can predict surgical condition in pregnant patients.METHODS: A retrospective, cross-sectional study was conducted on 46 pregnant patients who underwent non-enhanced appendix MRI in suspicion of acute appendicitis from 2010 to 2016. Differential diagnoses of appendix MRI were analyzed and blood tests were compared between those who had surgical and non-surgical disease.RESULTS: Appendix MRI differentiated two surgical disease; acute appendicitis and ovarian torsion; and various non-surgical conditions such as uterine myoma, hydronephrosis, ureterolithiasis and diverticulitis among clinically suspected acute appendicitis in pregnancy. The diagnostic accuracy of MRI for acute appendicitis in this study was 93.5%. Patients who had surgical disease showed significantly higher WBC count(≥11,000/mm^3), proportion of neutrophils in the WBC(≥79.9%), neutrophil-to-lymphocyte ratio(NLR≥6.4), levels of C-reactive protein(CRP≥1.82 mg/dL) and bilirubin(≥0.66 mg/dL) than those who had non-surgical disease.CONCLUSION: MRI can reliably differentiate surgical conditions and several blood tests(WBC, proportion of neutrophils in the WBC, NLR, CRP, bilirubin) can help anticipate acute surgical condition among pregnant patients suspected to have acute appendicitis.展开更多

We measured the MOD and the MMT at the thickest point of the appendix. Patients were categorized into two groups according to their medical records： patients who had surgery （surgical appendix group） and patients who did not have surgery （non-surgical appendix group）. Data were analyzed by MedCalc v.9.3. The rank sum test （Mann-Whitney test） was used to evaluate the difference in the MOD and the MMT between the two groups. ROC curve analysis was used to determine the optimal cut-off value of the MOD and the MMT on diagnosis of acute appendicitis.RESULTS： There were 121 appendixes （73.8%） in the non-surgical appendix group and 43 appendixes （26.2%） in the surgical appendix group. The median MOD differed significantly between the two groups （0.37 cm vs 0.76 cm, P〈 0.0001）, and the median MMT also differed （0.15 cm vs 0.33 cm, P 〈 0.0001）. The optimal cut-off value of the MOD and the MMT for diagnosis of acute appendicitis in children was 〉 0.57 cm （sensitivity 95.4%, specificity 93.4%） and 〉 0.22 cm （sensitivity 90.7%, specificity 79.3%）, respectively.CONCLUSION： The MOD and the MMT are reliable criteria to diagnose acute appendicitis in children. An MOD 〉 0.57 cm and an MMT 〉 0.22 cm are the optimal criteria.展开更多

文摘BACKGROUND Acute appendicitis(AAp)is a prevalent medical condition characterized by inflammation of the appendix that frequently necessitates urgent surgical procedures.Approximately two-thirds of patients with AAp exhibit characteristic signs and symptoms;hence,negative AAp and complicated AAp are the primary concerns in research on AAp.In other terms,further investigations and algorithms are required for at least one third of patients to predict the clinical condition and distinguish them from uncomplicated patients with AAp.AIM To use a Stochastic Gradient Boosting(SGB)-based machine learning(ML)algorithm to tell the difference between AAp patients who are complicated and those who are not,and to find some important biomarkers for both types of AAp by using modeling to get variable importance values.METHODS This study analyzed an open access data set containing 140 people,including 41 healthy controls,65 individuals with uncomplicated AAp,and 34 individuals with complicated AAp.We analyzed some demographic data(age,sex)of the patients and the following biochemical blood parameters:White blood cell(WBC)count,neutrophils,lymphocytes,monocytes,platelet count,neutrophil-tolymphocyte ratio,lymphocyte-to-monocyte ratio,mean platelet volume,neutrophil-to-immature granulocyte ratio,ferritin,total bilirubin,immature granulocyte count,immature granulocyte percent,and neutrophil-to-immature granulocyte ratio.We tested the SGB model using n-fold cross-validation.It was implemented with an 80-20 training-test split.We used variable importance values to identify the variables that were most effective on the target.RESULTS The SGB model demonstrated excellent performance in distinguishing AAp from control patients with an accuracy of 96.3%,a micro aera under the curve(AUC)of 94.7%,a sensitivity of 94.7%,and a specificity of 100%.In distinguishing complicated AAp patients from uncomplicated ones,the model achieved an accuracy of 78.9%,a micro AUC of 79%,a sensitivity of 83.3%,and a specificity of 76.9%.The most useful biomarkers for confirming the AA diagnosis were WBC(100%),neutrophils(95.14%),and the lymphocyte-monocyte ratio(76.05%).On the other hand,the most useful biomarkers for accurate diagnosis of complicated AAp were total bilirubin(100%),WBC(96.90%),and the neutrophil-immature granulocytes ratio(64.05%).CONCLUSION The SGB model achieved high accuracy rates in identifying AAp patients while it showed moderate performance in distinguishing complicated AAp patients from uncomplicated AAp patients.Although the model's accuracy in the classification of complicated AAp is moderate,the high variable importance obtained is clinically significant.We need further prospective validation studies,but the integration of such ML algorithms into clinical practice may improve diagnostic processes.
文摘BACKGROUND Laparoscopic surgery has emerged as the preferred treatment for acute appendicitis,a common acute abdominal condition.Despite surgical advances,postoperative gastrointestinal dysfunction and delayed recovery continue to negatively impact rehabilitation outcomes and patient quality of life.Laser acupuncture represents a promising emerging complementary therapy with potential benefits for promoting functional recovery.AIM To evaluate the clinical efficacy of laser acupuncture in enhancing gastrointestinal function recovery following laparoscopic appendectomy and to investigate its potential applications in postoperative rehabilitation.METHODS This retrospective controlled clinical study selected 120 acute appendicitis patients who underwent laparoscopic appendectomy from January 2022 to December 2023 at a tertiary hospital.Patients were randomly divided into two groups:Routine treatment group(n=60)and laser acupuncture intervention group(n=60).There were no significant statistical differences in baseline characteristics(age,gender,body mass index,appendicitis severity)between the two groups.The routine treatment group received standard postoperative care,while the laser acupuncture intervention group received additional laser acupuncture treatment on top of standard care.Key observation indicators included time to first exhaust,time to first bowel movement,time to gastrointestinal function recovery,and postoperative complication rates.RESULTS Patients in the laser acupuncture intervention group showed significantly faster gastrointestinal function recovery compared to the routine treatment group.Specifically,time to first exhaust was significantly shortened(intervention group:12.5±2.3 hours vs control group:18.7±3.1 hours,P<0.05),time to first bowel movement was earlier(intervention group:36.4±4.6 hours vs control group:48.2±5.7 hours,P<0.05),postoperative complication rate was significantly reduced(intervention group:8.3%vs control group:20.0%,P<0.05),postoperative pain score was significantly lower(intervention group:3.2±1.1 vs control group:4.7±1.5,P<0.05),and intestinal motility recovery was faster and more effective.CONCLUSION Laser acupuncture,as an auxiliary treatment method,can significantly promote gastrointestinal function recovery in patients after laparoscopic appendectomy,reduce complications,and improve postoperative comfort.This technique has advantages such as minimal invasiveness,rapid recovery,and few side effects,making it worthy of further clinical promotion and application.
文摘BACKGROUND Non-operative management(NOM)for uncomplicated acute appendicitis(AA)has been gaining popularity in recent years.One of the major concerns with NOM is the recurrence rate of AA following NOM.AIM To investigate the impact of the presence of an appendicolith and its specific characteristics on the recurrence rate of AA following NOM.METHODS A retrospective analysis identified all patients treated with NOM for AA,at our institute between 2016 and 2024.Patients with an appendicolith on imaging were identified and their course and outcomes were compared with patients who were treated with NOM without an appendicolith.The primary outcome was defined as a recurrence of AA.RESULTS During the study period,797 patients were treated with NOM for AA.Their mean age was 25.4 years±14.4 years,and 45.4%were females.Only 68 patients(8.5%)had an appendicolith identified on imaging.Patients with an appendicolith had a larger appendix diameter(10.2 mm±4 mm vs 8.5 mm±2.1 mm,P=0.001).There was no difference in the recurrence rate of patients with and without an appendicolith(26.5%vs 19.1%,P=0.14),however patients with an appendicolith presented with a shorter time to recurrence of appendicitis(3.9 months±10.4 months vs 5.9 months±8.1 months,P=0.04).In a sub analysis,the number of appendicoliths,its size,and its location,did not influence the recurrence rate.CONCLUSION This study demonstrates that patients with appendicoliths have a shorter time to recurrence after NOM of AA,but do not experience higher overall recurrence rates.

文摘BACKGROUND Endoscopic retrograde appendicitis therapy(ERAT)is an emerging technique.However,its efficacy remains uncertain,and postoperative complications often exacerbate inflammation,thereby increasing the difficulty of surgery.The use of ERAT in appendicitis remains contentious,prompting the presentation of this case report.CASE SUMMARY We report the case of a 43-year-old female patient presenting with intermittent right lower abdominal pain for one day.The patient had undergone ERAT six months previously.Examination revealed stent impaction in the appendix,leading to exacerbated inflammation.Subsequently,a solo single-incision laparo-scopic appendectomy(SSLA)was performed.The ERAT-related complications increased surgical difficulty and prolonged the operation time.Post-SSLA,the patient was hospitalized for one day and showed favorable recovery upon follow-up.CONCLUSION This case highlights the risks of ERAT.Thorough preoperative assessment,proper stent placement during surgery and regular postoperative follow-up are crucial in preventing complications,as their occurrence can increase surgical difficulty.Compared to ERAT,SSLA remains more widely used in clinical practice.Both techniques require further clinical data and research to optimize their application.
文摘Acute appendicitis remains one of the most common causes of emergency abdominal surgery globally.Imaging plays a pivotal role in confirming or excluding the diagnosis and identifying complications that influence management pathways.This narrative review synthesizes contemporary evidence and consensusbased imaging protocols for appendicitis,with a focus on computed tomography,magnetic resonance imaging,and ultrasound.The article explores advanced diagnostic criteria,interpretation challenges,imaging algorithms derived from professional society guidelines,and special considerations including pregnancy and pediatric populations.Clinical practice recommendations by the World Society of Emergency Surgery,European Association of Endoscopic Surgery,American College of Radiology,and Infectious Diseases Society of America are incorporated to frame best practices.
文摘BACKGROUND Ovarian vein thrombosis(OVT)is a rare condition that most commonly affects postpartum women.It is particularly prevalent in the first 10 days postpartum,a period when women are more prone to developing this condition.The right ovarian vein is often affected due to its tortuous nature and less competent valves.OVT presents similarly to acute abdominal conditions,such as acute appendicitis,especially when the right ovarian vein is involved.Given the overlap in clinical presentation,diagnosis requires high-quality imaging techniques and a high degree of suspicion.CASE SUMMARY Herein,we report a rare case of OVT in a young postpartum female who presented to the emergency department with signs and symptoms of acute abdomen.The patient had a history of pulmonary tuberculosis treatment.A provisional diagnosis of a perforated appendix was made,and a lower midline exploratory laparotomy was planned.During surgery,the appendix and inte-stines appeared normal,but a distended and thrombosed right ovarian vein was found.The affected ovarian vein was excised,and the patient was placed on anti-coagulants postoperatively.The recovery was unremarkable,and anticoagulants were continued for six months.CONCLUSION OVT is most commonly seen in the early postpartum period,especially within the first 10 days.Due to its anatomical characteristics,the right ovarian vein is more commonly involved.The clinical presentation of OVT can closely mimic acute abdomen or acute appendicitis,making diagnosis challenging.Accurate diagnosis requires a high index of suspicion and advanced imaging techniques to differentiate OVT from other conditions with similar presentations.
文摘Objective:To analyze the effects of combined spinal-epidural anesthesia and epidural anesthesia in patients undergoing appendicitis surgery.Methods:Seventy-eight patients who underwent surgical treatment for appendicitis from February 2022 to February 2025 were selected as samples and randomly divided into two groups.The study group received combined spinal-epidural anesthesia,while the control group received epidural anesthesia.Anesthesia indicators,vital signs,and complication indicators were compared between the two groups.Results:The onset time of anesthesia in the study group was shorter than that in the control group,the visual analog scale(VAS)score was lower than that in the control group,and the highest plane of anesthesia block was lower than that in the control group(P<0.05).At 15 minutes after anesthesia induction and at the end of surgery,the heart rate(HR),mean arterial pressure(MAP),and blood oxygen saturation(SPO2)in the study group were significantly different from those in the control group(P<0.05).The complication rate in the study group was lower than that in the control group(P<0.05).Conclusion:Combined spinal-epidural anesthesia for appendicitis surgery can reduce the impact of anesthesia on vital signs,shorten the onset time of anesthesia,and is highly effective and feasible.
文摘BACKGROUND Appendicitis is an abdominal medical emergency and can be of various types.It can lead to a series of gastrointestinal symptoms and can affect health status.Therefore,attention should be paid to the diagnosis of appendicitis to improve prognosis.AIM To assess the value of transabdominal superficial ultrasonography(TASU)in the clinical diagnosis of various types of appendicitis.METHODS A total of 100 patients suspected to have acute appendicitis that were admitted to our hospital between July 2022 and July 2024 were selected for this study.All of them underwent conventional abdominal ultrasonography and TASU.Taking surgical pathology as the gold standard,the diagnostic efficacy of the two ultrasonographic examinations was compared,and the ultrasonographic features of patients with different types of appendicitis were analyzed.RESULTS Comparison with the gold standard showed that among the 100 patients suspected of appendicitis,72 cases were diagnosed as appendicitis while 28 cases were deemed to be normal.Compared with conventional abdominal ultrasonography,TASU displayed a higher diagnostic efficiency(P<0.05).Among the 72 patients with acute appendicitis,22 cases were diagnosed as simple appendicitis,26 cases as suppurative appendicitis,and 24 cases as gangrenous appendicitis.TASU was more effective in the diagnosis of the various types of appendicitis,and the difference was significant between groups(P<0.05).Ultrasonography radiographs revealed an enlarged appendix with a tubular anechoic area,a widened lumen,with a visible occlusion or stercoral shadow and a cystic mass in the parenchyma.CONCLUSION TASU can accurately diagnose appendicitis and also be used to identify the various types of appendicitis,thereby having application value.
文摘Appendicoliths are frequently encountered in acute appendicitis(AA)and historically considered a risk factor for treatment failure in nonoperative management(NOM).However,the impact of appendicoliths on recurrence rates in uncomplicated AA remains controversial.This editorial critically appraises the study by Kupietzky et al,which explored the relationship between appendicolith characteristics and NOM outcomes.Kupietzky et al conducted a retrospective analysis of 797 patients with uncomplicated AA,comparing recurrence rates between those with and without appendicoliths.The study focused on long-term follow-up(median 44.2 months)and subgroup analyses of stone characteristics.The study revealed no significant difference in overall recurrence rates between groups(26.5%vs 19.1%,P=0.14).However,patients with appendicoliths experienced earlier recurrence(3.9 months vs 5.9 months,P=0.04)and had larger appendix diameters(10.2 mm vs 8.5 mm,P=0.001).Subgroup analyses showed no correlation between stone size,location,or number and recurrence risk.Appendicoliths do not independently increase the overall recurrence risk after NOM for uncomplicated AA but may accelerate recurrence timelines.Clinical decisions should prioritize individualized risk assessment,considering patient age,symptom severity,and radiological features.These findings challenge traditional paradigms and advocate for shared decision-making between clinicians and patients.
文摘BACKGROUND Chronic schistosomiasis causes multiple organ and multiple system diseases,especially the digestive system.Schistosome eggs are mainly deposited in the stomach,liver and colorectal,but a few eggs are deposited in the appendix and cause disease.At present,there are few studies on schistosomal appendicitis.AIM To explore the differences in epidemiological,clinical and pathological characteristics between schistosomal appendicitis and non-schistosomal appendicitis over the past decade in order to assess the impact of schistosomiasis on appendicitis.METHODS The differences of general data,clinical data and laboratory examination data of patients with appendicitis from October 2013 to October 2023 were retrospectively analyzed.All patients were divided into two groups for analysis.There were 136 patients in schistosomal appendicitis group and 5418 patients in non-schistosomal appendicitis group.RESULTS Schistosomal appendicitis accounted for 2.45%of all patients with appendicitis,and the annual proportion in the past decade was 2.2%,2.9%,1.8%,1.9%,3.4%,3.1%,1.9%,1.6%,3%,2.6%,respectively.The prevalence of schistosomal appendicitis was middle-aged and elderly males,with an average age of 61.73±15.335 years.The main population of non-schistosomal appendicitis was middle-aged men,with an average age of 35.8±24.013 years(P<0.001).The distribution of pathological types of appendicitis was different between the two groups(P<0.001).The incidence of acute suppurative appendicitis in non-schistosomal appendicitis was higher than that in schistosomal appendicitis[odds ratio(OR)=0.504;95%confidence interval(CI):0.349-0.728;P<0.001].The proportion of acute attack of chronic appendicitis in schistosomal appendicitis was higher than that in non-schistosomal appendicitis(OR=2.614;95%CI:1.815-3.763;P<0.001).The proportion of schistosomal appendicitis patients complicated with colorectal cancer was higher than that of nonschistosomal appendicitis patients(OR=5.087;95%CI:1.427-18.132;P=0.012).There was no difference in clinical symptoms between the two groups.In the laboratory examination,there was a significant difference in white blood cells between schistosomal appendicitis and non-schistosomal appendicitis.The level of white blood cells in schistosomal appendicitis group was slightly higher than the upper limit of the normal range.Other statistically significant indicators were in the normal range.CONCLUSION Schistosomal appendicitis is a severe condition that is often associated with intestinal malignancies,potentially leading to a poor prognosis.Schistosomal appendicitis is more likely to be misdiagnosed and missed diagnosed in clinical work because of its nonspecific clinical manifestations and laboratory examination.It is crucial to differentiate schistosomal appendicitis in middle-aged and elderly male patients presenting with appendicitis,and to ensure early detection and treatment.
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 improve the diagnostic accuracy in patients with symptoms and signs of appendicitis, but without confirmative computed tomography (CT) findings.
文摘BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is chal enging. Although magnetic resonance imaging(MRI) is the most accurate modality to diagnose acute appendicitis in pregnant patients, it is often used as a last resort because of high cost and long scan time. We performed this study to analyze differential diagnoses of appendix MRI and to investigate if there are any blood tests that can predict surgical condition in pregnant patients.METHODS: A retrospective, cross-sectional study was conducted on 46 pregnant patients who underwent non-enhanced appendix MRI in suspicion of acute appendicitis from 2010 to 2016. Differential diagnoses of appendix MRI were analyzed and blood tests were compared between those who had surgical and non-surgical disease.RESULTS: Appendix MRI differentiated two surgical disease; acute appendicitis and ovarian torsion; and various non-surgical conditions such as uterine myoma, hydronephrosis, ureterolithiasis and diverticulitis among clinically suspected acute appendicitis in pregnancy. The diagnostic accuracy of MRI for acute appendicitis in this study was 93.5%. Patients who had surgical disease showed significantly higher WBC count(≥11,000/mm^3), proportion of neutrophils in the WBC(≥79.9%), neutrophil-to-lymphocyte ratio(NLR≥6.4), levels of C-reactive protein(CRP≥1.82 mg/dL) and bilirubin(≥0.66 mg/dL) than those who had non-surgical disease.CONCLUSION: MRI can reliably differentiate surgical conditions and several blood tests(WBC, proportion of neutrophils in the WBC, NLR, CRP, bilirubin) can help anticipate acute surgical condition among pregnant patients suspected to have acute appendicitis.
文摘MM： To evaluate the maximal-outer-diameter （MOD） and the maximal-mural-thickness （MMT） of the appendix in children with acute appendicitis and to determine their optimal cut-off values to diagnose acute appendicitis.METHODS： In total, 164 appendixes from 160 children between 1 and 17 years old （84 males, 76 females; mean age, 7.38 years） were examined by high-resolution abdominal ultrasound for acute abdominal pain and the suspicion of acute appendicitis. We measured the MOD and the MMT at the thickest point of the appendix. Patients were categorized into two groups according to their medical records： patients who had surgery （surgical appendix group） and patients who did not have surgery （non-surgical appendix group）. Data were analyzed by MedCalc v.9.3. The rank sum test （Mann-Whitney test） was used to evaluate the difference in the MOD and the MMT between the two groups. ROC curve analysis was used to determine the optimal cut-off value of the MOD and the MMT on diagnosis of acute appendicitis.RESULTS： There were 121 appendixes （73.8%） in the non-surgical appendix group and 43 appendixes （26.2%） in the surgical appendix group. The median MOD differed significantly between the two groups （0.37 cm vs 0.76 cm, P〈 0.0001）, and the median MMT also differed （0.15 cm vs 0.33 cm, P 〈 0.0001）. The optimal cut-off value of the MOD and the MMT for diagnosis of acute appendicitis in children was 〉 0.57 cm （sensitivity 95.4%, specificity 93.4%） and 〉 0.22 cm （sensitivity 90.7%, specificity 79.3%）, respectively.CONCLUSION： The MOD and the MMT are reliable criteria to diagnose acute appendicitis in children. An MOD 〉 0.57 cm and an MMT 〉 0.22 cm are the optimal criteria.

文摘Acute abdominal pain with signs and symptoms of peritonitis due to sudden extravasation of chyle into the peritoneal cavity is a rare condition that is often mistaken for other disease processes. The diagnosis is rarely suspected preoperatively. We report a case of spontaneous chylous peritonitis that presented with typical symptoms of acute appendicitis such as intermittent fever and epigastric pain radiating to the lower right abdominal quadrant before admission.
文摘Schistosomal appendicitis(SA)is a rare but serious complication of schistosomiasis,a parasitic disease affecting over 250 million people worldwide.A recent retrospective study by Wang et al provides important insights into the clinicopathological characteristics of SA.The study compared 136 cases of SA to 5418 cases of non-SA over a ten-year period.Key findings include a higher average age of SA patients(61.73 years vs 35.8 years for non-SA),a higher proportion of acute on chronic appendicitis(33.1%vs 16%),and a significantly higher incidence of colorectal cancer(11.7%vs 2.2%).Despite these differences,SA remains a diagnostic challenge due to its nonspecific clinical presentation and lack of specific laboratory findings.The study also highlights the persistent prevalence of SA,accounting for 1.6%-3.4%of all appendicitis cases each year from 2013 to 2023.These findings underscore the need for enhanced awareness,early detection,and prompt treatment of SA in endemic regions.Given the association with colorectal cancer,patients with SA require thorough screening and follow-up.Further research into the pathogenesis and diagnostic markers of SA is warranted.As the global battle against schistosomiasis continues,targeted efforts to diagnose and manage SA can significantly improve patient outcomes.
文摘BACKGROUND:Ultrasound has the first line investigation role in the diagnosis of acute appendicitis in children.The purpose of this study was to perform a quality assessment review on the visualization rate of appendix on ultrasound in children in the community hospital setting.METHODS:A retrospective chart review of the abdominal ultrasound findings for the visualization of the appendix was performed on paediatric patients ranging from 5 to 18 years.Data were collected from the two community hospitals of Toronto by using hospital electronic medical record for the ultrasound findings in patients presented with abdominal pain.RESULTS:Data from two community hospitals indicated visualization rate of the appendix as 11.0%and 23.2%for site 1 and site 2 respectively.In cases where the ultrasound was repeated the visualization rate remains the same.A two-proportion z-test was performed to find whether the visualization of appendix increases the likelihood of diagnosing appendicitis.The results revealed that the visualization of an appendix(P=0.52),significantly improved the diagnosis of appendicitis(z=34,P<0.001).CONCLUSION:Visualization of an appendix on ultrasound increases the likelihood of correctly diagnosing appendicitis.In our study,we found low visualization rate of appendix on ultrasound that could be the result of many factors that contribute towards the low visualization rate of an appendix on ultrasound.Hence,the challenges in identifying appendix should be minimized to improve the visualization and diagnosis of appendicitis on ultrasound.
文摘Objective:To investigate the value of systemic inflammatory response index(SIRI)and systemic immune-inflammation index(SII)in predicating acute appendicitis complications based on hemogram parameters.Methods:Demographic data,histopathological studies,and laboratory results of the patients who were admitted to the emergency department with a complaint of abdominal pain between January 2020 and June 2022 and were hospitalized with the diagnosis of acute appendicitis for operation by general surgery were examined.Simple appendicitis and complicated appendicitis groups were compared in terms of parameters according to their histopathological examinations.Results:A total of 220 patients who met the inclusion criteria were included in our study.Mean SIRI levels were found to be significantly higher in the complicated appendicitis group than in the simple appendicitis group[6.60(4.07,14.40)vs.3.50(2.20,6.80);P=0.002].Similarly,SII levels were found to be significantly higher in the complicated appendicitis group compared to the simple appendicitis group[2514.50(1132.25,5388.00)vs.1207.00(571.50,2089.00),P<0.001].The power of SIRI and SII to indicate complications was higher than white blood cell count and C-reactive protein(area under the curve:0.753 and 0.786,respectively).Conclusion:SIRI and SII could be used to indicate complications in patients with acute appendicitis.

文摘BACKGROUND Because of the mild inflammatory status in acute uncomplicated appendicitis,our team developed a novel technical protocol for single-port laparoscopic appendec-tomy using needle-type grasping forceps(SLAN)and achieved positive clinical outcomes.However,the intraoperative procedure lacked stability and fluency due to a series of problems highlighted by the small incision design of the proto-col(only 1 cm long).Therefore,there is a growing clinical demand to further opti-mize the SLAN protocol.CASE SUMMARY An adult male patient was admitted for persistent right lower abdominal pain with preoperative computed tomography findings suggestive of appendicitis accompanied by localized peritonitis.A modified technical protocol for SLAN based on minimally invasive surgical principles was used,and the patient was confirmed to have acute simple appendicitis by postoperative pathological ana-lysis.Postoperative recovery was uneventful,and no postoperative complications,such as incision infection or severe incision pain,were observed.The patient was discharged successfully on postoperative day 2.CONCLUSION The modified technical protocol of SLAN may be a new minimally invasive surgical alternative for patients with acute simple appendicitis.
文摘We read with interest the review by Teng et al,who summarized the current approach to the diagnosis and treatment of acute appendicitis(AA).Also,the article summarizes the clinical scoring systems very effectively.In one of the previous studies conducted by our research group,we showed that the use of the Alvarado score,ultrasound and C-reactive protein values in combination provides a safe confirmation or exclusion of the diagnosis of AA.Computed tomography is particularly sensitive in detecting periappendiceal abscess,peritonitis and gangrenous changes.Computed tomography is not a good diagnostic tool in pediatric patients because of the ionizing radiation it produces.Ultrasound is a valuable diagnostic tool to differentiate AA from lymphoid hyperplasia.Presence of fluid collection in the periappendiceal and lamina propria thickness less than 1 mm are the most effective parameters in differentiating appendicitis from lymphoid hyperplasia.Although AA is the most common cause of surgical acute abdomen,it remains an important diagnostic and clinical challenge.By combining clinical scoring systems,laboratory data and appropriate imaging methods,diagnostic accuracy and adherence to treatment can be increased.Lymphoid hyperplasia and perforated appendicitis present significant diagnostic challenges in children.Additional ultrasound findings are increasingly defined to differentiate AA from these conditions.
