Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant(both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments(1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of lap-aroscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.展开更多
目的:探讨手助腹腔镜(HALS)行结肠癌根治术的临床效果。方法:将2010年1月—2011年5月住院的结肠癌患者,随机分成HALS组(21例),传统腹腔镜(LS)组(25例)和常规开腹组(24例),对其临床资料效果进行对比分析。结果:HALS组21例全部完成HALS,LS...目的:探讨手助腹腔镜(HALS)行结肠癌根治术的临床效果。方法:将2010年1月—2011年5月住院的结肠癌患者,随机分成HALS组(21例),传统腹腔镜(LS)组(25例)和常规开腹组(24例),对其临床资料效果进行对比分析。结果:HALS组21例全部完成HALS,LS组23例完成LS,2例中转开腹,但两组中转率差异无统计学意义。HALS组较LS组平均手术时间短(153.9 min vs.171.7 min)(P=0.011)。HALS组与LS组相比术中失血量、平均住院日、总费用、术后排气时间、淋巴结清扫数目均无统计学差异(均P>0.05)。与开腹组比较,HALS组手术时间有所增加(153.9 min vs.131.8 min)(P=0.002),但术中失血量,术后排气时间,住院时间均明显缩短(均P<0.05),两组清除淋巴结数量无统计学差异。结论:HALS结肠癌根治术同样具备传统腹腔镜手术微创,安全,术后恢复快的优点,同时缩短了手术时间。展开更多

Odds ratios or mean differences were calculated with 95% confidence intervals for fixed-effects and random-effects models. Overall, 754 patients from16 trials who met the inclusion criteria were selected.RESULTS In pure splenectomy, blood loss volume(P < 0.001) and conversion rate(P =0.008) were significantly lower in the HALS group than in the LS group.Conversely, for splenomegaly, the operative time(P = 0.04) was shorter and blood loss volume(P < 0.001) and conversion rate(P = 0.001) were significantly lower in the HALS group than in the LS group. However, no significant difference was observed in hospital stay length, blood transfusion, time to food intake, complications, or mortality rate between the two groups. Moreover, in splenectomy and devascularization of the upper stomach(DUS), the operative time(P = 0.04) was significantly shorter and blood loss volume(P < 0.001) andconversion rate(P = 0.05) were significantly lower in the HALS + DUS group than in the LS + DUS group. However, no significant difference was observed in hospital stay length, timing of diet, and complications between the two groups.CONCLUSION HALS is an ideal surgical treatment method for splenomegaly because it can maximize the benefits for patients while maintaining the advantages of LS.展开更多
