Objective To evaluate the clinical effectiveness of laparoscopic and open appendectomy. Methods Literatures relating to randomized controlled trials in English and Chinese on the comparison of clinical effectiveness after laparoscopic and open appendectomy in appendicitis from PubMed，Wiley Online Library，Medline，Embase，Cochrane，CNKI，VIP，CBM databases were extracted，and methodological quality was evaluated by two reviewers independently with designed extraction form. The Cochrane Collaboration’s RevMan 4.2.2 software was used for data analysis. The wound infection，hospitalization time，operation time，hospitalization expenses，and peritoneal abscess were compared between laparoscopic and open appendectomy. Results Eight published reports of eligible studies were extracted. Compared with the open appendectomy， laparoscopic appendectomy had significant differences in lower wound infection rate 〔OR=0.19，95%CI （0.09，0.38），P＜0.000 01〕， longer operation time 〔WMD=3.66，95%CI （0.50，6.82），P=0.02〕，and more hospitalization expenses〔WMD=503.96，95%CI （337.23，670.70），P＜0.000 01〕.But there were no significant differences in hospitalization time〔WMD=-0.11，95%CI （-3.64，3.43），P=0.95〕 and incidence rate of peritoneal abscess 〔OR=1.40，95%CI （0.23，8.64），P=0.71〕 between laparoscopic and open appendectomy. Conclusions The wound infection rate is lower，but the operation time is longer，the hospitalization expenses is more in laparoscopic appendectomy as compared with open appendectomy. There are no statistically significant differences of hospitalization time and incidence rate of abdominal abscess between laparoscopic and open appendectomy.
目的探讨经脐单孔腹腔镜联合胃镜治疗微小胃间质瘤(gastric stromal tumors, GIST)的可行性和临床疗效。 方法回顾性分析我院2010年10月至2011年5月期间行经脐单孔腹腔镜联合胃镜治疗微小GIST 30例患者的临床资料。 结果30例病灶直径（1.0±0.2） cm（0.5～2.0 cm），术后病理检查均证实为极低危险程度GIST。 24例在单孔腹腔镜辅助下成功完成内镜黏膜下剥离术（endoscopic submucosal dissection，ESD）； 3例因ESD术中发生胃壁穿孔而改行内镜全层切除术（endoscopic full-thickness resection, EFR），其中2例继续在单孔下完成穿孔修补术，1例于左上腹壁另加一 Trocar，在双孔下完成穿孔修补术； 另3例因ESD剥离瘤体困难，改行胃局部切除术，其中2例继续在单孔下完成手术，1例在双孔下完成手术。 ESD成功率为80.0%（24／30），经脐部单孔完成率为93.3%（28/30）。手术时间（87.5±10.3） min （45～150 min）。 全组术后（4.3±0.5） d （3～8 d）出院。术后随访期3～7个月（平均4.6个月），均无病变复发。 结论经脐部单孔腹腔镜联合胃镜治疗微小GIST是安全可行的，早期疗效令人满意。
