Objective To systematically review the effectiveness and safety of single-incision laparoscopic cholecystectomy (SILC) versus conventional multiport laparoscopic cholecystectomy (CMLC). Methods We electronically searched PubMed, EMbase, The Cochrane Library (Issue 1, 2013), CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) on SILC versus CMLC from inception to January 1st, 2013. According to the Cochrane methods, the reviewers screened literature, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.2 software. Results Finally, 17 RCTs involving 1 233 patients were included. The results of meta-analysis showed that, compared with CMLC, SILC was lower in 24 h postoperative pain score (visual analogue scale, VAS) (SMD= –0.40, 95%CI –0.76 to –0.04, P=0.03), higher in cosmetic results score (SMD=1.56, 95%CI 0.70 to 2.43, P=0.000 4), and longer in operative time (MD=13.11, 95%CI 7.06 to 19.16, Plt;0.000 1). However, no significant difference was found in 6 h postoperative pain scores (VAS), postoperative complications, port-site hernia and hospital stay between the two groups. Conclusion SILC is a safe and effective technique for the treatment of uncomplicated benign gallbladder diseases, and it has certain advantages compared with CMLC, which is recommended in clinical application.
Objective To summarize the experience of single incision laparoscopic colorectal surgery and to discuss the operative techniques. Methods The clinical data of 21 cases who underwent single incision laparoscopic colorectal surgery in Shengjing Hospital from Jan. 2010 to Jun. 2011 were collected and analyzed. Results Of 21 cases underwent single incision laparoscopic surgery， right hemicolectomy performed in 5 cases， sigmoidectomy performed in 2 cases， rectal anterior resection performed in 9 cases， rectal abdominoperineal resection performed in 2 cases， total colectomy performed in 1 case， and colostomy performed in 2 cases. Twenty cases completed by single incision， but 1 case was added an extra 12 mm incision in order to dissect the lower segment of rectum. The operative time was （189±75） min （40-335min）；the postoperative hospitalization time was （11.5±3.4） d （7-16d）. There were no bleeding， anastomosis leakage or intestinal obstruction after operation， and no incision infection， rupture or hernia were founded. No recurrence was found within 6 months’ follow up after operation. Conclusions Under reasonable selection of indication， single incision laparoscopic colorectal surgery is safe and feasible， and it also has a satisfactory cosmetic effect and better minimally invasive effect.
目的 探讨利用常规腹腔镜器械完成经脐单孔腹腔镜结直肠手术的可能性和技术要点。方法 收集中国医科大学附属盛京医院微创外科于2009年4月至2010年1月期间施行的12例经脐单孔腹腔镜结直肠手术的临床资料。阑尾炎8例，均为女性，平均年龄40岁； 回盲部肿物2例，均为女性，其中1例为回盲部淋巴水瘤（68岁），另1例为回盲部溃疡性结肠炎（47岁）； 乙状结肠息肉1例，女，55岁； 直肠癌1例，男，52岁。 12例均于脐部行2.5~3.0 cm长单切口，利用常规腹腔镜手术器械完成手术。结果 8例阑尾手术，手术时间20~50 min，出血量均少于10 ml； 2例回盲部切除术手术时间分别为60 min和90 min，出血量分别为10 ml和20 ml； 1例乙状结肠切除术用时120 min，术中出血约50 ml，术后4 d拔除引流管； 直肠癌手术时间210 min，术中出血少于200 ml，术后1周拔除引流管并出院。结论 利用常规腹腔镜手术器械完成经脐单孔腹腔镜结直肠手术安全可行。
目的 探讨应用传统器械经脐行改良单孔腹腔镜阑尾切除术的临床价值。方法 回顾性分析笔者所在医院2010年1月至2012年2月期间行经脐单孔腹腔镜阑尾切除术的52例阑尾炎患者的临床资料，总结手术经验。结果 52例患者均顺利完成手术，平均手术时间为39.2min （18～70min），术后平均住院时间为5d （3～12d）。其中，45例患者成功完成经脐单孔腹腔镜阑尾切除术，2例中转开腹，2例行两孔LA术，3例行三孔LA术。术后2例患者发生切口感染。29例患者获访，随访时间4～18个月，平均12个月，无出血、切口疝、腹腔残余感染、粘连性肠梗阻、阑尾残端瘘等并发症发生。结论 应用传统器械经脐行改良单孔腹腔镜阑尾切除术简单、安全、可行、患者恢复快、并发症少、美容效果较好，但操作难度相对更高。应严格掌握手术适应证，必要时及时增加戳孔或中转开腹。
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。
目的比较单孔腹腔镜与传统腹腔镜胆囊切除术的临床效果。 方法选取2012年9月至2013年5月期间于我院就诊的胆囊良性疾病患者，分别接受单孔腹腔镜胆囊切除术（单孔腹腔镜组，45例）和传统腹腔镜胆囊切除术（传统腹腔镜组，48例），分别观察并对比2组患者的手术时间、术中出血量、术后（6 h和24 h）疼痛评分、止疼药物的应用率、术后住院时间及患者对切口的满意度。 结果2组患者术前的一般特征差异无统计学意义（P＞0.05）。单孔腹腔镜组的手术时间明显长于传统腹腔镜组〔（59.11±14.15）min比（40.21±11.11）min，P=0.00〕，术后6 h疼痛评分及止痛药物应用率均明显低于传统腹腔镜组〔6 h疼痛评分：（3.33±1.41）分比（4.60±1.30）分，P=0.00；止痛药物应用率：6.67%（3/45）比31.25%（15/48），P=0.04〕，术后患者对切口的满意度评分明显高于传统腹腔镜组〔（4.76±6.00）分比（2.60±0.76）分，P=0.02〕。单孔腹腔镜组和传统腹腔镜组的术中出血量、术后24 h疼痛评分及术后住院时间比较差异均无统计学意义〔术中出血量：（14.67±4.80）mL比（13.85±3.85）mL，P=0.36；24 h疼痛评分：（1.60±0.65）分比（1.80±0.70）分，P=0.14；术后住院时间：（3.11±0.77）d比（3.06±0.67）d，P=0.75〕。2组均无并发症发生。 结论单孔腹腔镜较传统腹腔镜胆囊切除术可减轻术后疼痛，美容效果好，且并不增加手术风险。
ObjectiveTo analyze safety and feasibility of transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting. MethodsThe clinical data of 36 patients who diagnosed as hydrocephalus underwent ventriculoperitoneal shunting from May 2013 to August 2015 in this hospital were collected. Twelve patients were performed transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting (laparoscopy group) and 24 patients were performed laparotomy ventriculoperitoneal shunting (laparotomy group). The abdominal operation time, postoperative exhaust time, postoperative hospital stay, postoperative pain score, and postoperative complications rate were compared between the laparoscopy group and the laparotomy group. ResultsAll the operations were completed successfully. Compared with the laparotomy group, the abdominal operation time (P < 0.05), postoperative exhaust time (P < 0.05), and postoperative hospital stay (P < 0.05) were significantly shorter, the postoperative pain score was significantly less (P < 0.05) in the laparoscopy group. The postoperative complications rate had no significant difference between the laparoscopy group and the laparotomy group (P > 0.05). ConclusionsThe preliminary results of limited cases in this study show that transumbilical single-incision laparoscopic assisted ventriculoperitoneal shunting is safe and feasible, with better cosmetic. more comparative studies or randomized controlled trials are required to make a confirmed conclusion.
ObjectiveTo systematically review the effectiveness and safety of laparoendoscopic single-site surgery (LESS) for varicocele. MethodsSuch databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, and WanFang Data were electronically searched for studies about LESS and traditional laparoscopy for varicocele till March 1st, 2013. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of included studies was also assessed. Then, meta-analysis was performed using RevMan 5.1 software. ResultsSeven RCTs involving 452 cases were included. The results of meta-analysis showed that, there was no significant difference between LESS and traditional laparoscopy for varicocele on post-operational complications (RR=0.57, 95%CI 0.26 to 1.27, P=0.17), duration of hospital stay (MD=-0.30, 95%CI-0.87 to 0.26, P=0.30), improvement of semen parameters, and blood loss. However, LESS had longer duration of operation (MD=11.26, 95%CI 3.62 to 18.90, P=0.004). ConclusionThe effectiveness and safety of LESS and traditional laparoscopy for varicocele are similar, and LESS could achieve more beautiful and natural effects which has longer surgery time on account of non-proficiency in surgery and equipment. Due to the limited quantity and quality of the included studies, the above conclusion requires to be proved by more high quality randomized controlled trials.
