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

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: 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

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.
文摘目的:比较腹腔镜与开腹阑尾切除术治疗急性化脓性阑尾炎患者的效果。方法:回顾性分析2022—2024年该院收治的80例急性化脓性阑尾炎患者的临床资料,根据手术方法不同将其分为观察组和对照组各40例。观察组接受腹腔镜阑尾切除术治疗,对照组接受开腹阑尾切除术治疗,比较两组围手术期指标(手术时间、术中出血量、术后首次排气时间、住院时间)水平、术后疼痛程度[视觉模拟评分法(VAS)]评分、术后应激反应指标(血清皮质醇、去甲肾上腺素)水平和术后并发症发生率。结果:观察组手术时间、术后首次排气时间、住院时间均短于对照组,术中出血量少于对照组,差异有统计学意义(P<0.05);观察组术后12、24 h VAS评分均低于对照组,差异有统计学意义(P<0.05);观察组术后血清皮质醇、去甲肾上腺素水平均低于对照组,差异有统计学意义(P<0.05);观察组并发症发生率为5.00%(2/40),低于对照组的22.50%(9/40),差异有统计学意义(P<0.05)。结论:腹腔镜阑尾切除术治疗急性化脓性阑尾炎患者可改善围手术期指标水平,降低疼痛程度评分、术后应激反应指标水平和并发症发生率,效果优于开腹阑尾切除术治疗。
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.
