Background: Laparoscopic distal gastrectomy has been increasingly utilized in the treatment of gastric adenocarcinoma. This study aims to compare the morbidity/mortality and postoperative outcomes of laparoscopic-assisted versus open distal gastrectomy since 2000., Methods: A comprehensive search of MEDLINE and EMBASE was conducted including studies published between 2000 and present., Results: Seventeen studies with a total of 7,109 distal gastrectomies (3,496 lap vs 3,613 open) were included. Across all studies, postoperative morbidity rates for laparoscopic gastrectomy were lower than that of open [median (range) 10 (0-36) % vs 17 (0-43) %]. Meta-analysis of postoperative morbidity rates in prospective studies only yielded pooled odds ratio of 0.52 (95 % CI 0.33-0.81) (P = 0.004). In-hospital mortality rates were comparable between the two (range: laparoscopic 0-3.3 vs open 0-6.7 %). The long-term oncological outcomes of resection were difficult to analyze given variable reporting but appeared similar between the two. Meta-analysis of prospective studies showed that laparoscopic-assisted distal gastrectomy was associated with significantly shorter hospital length of stay [standard mean difference (SMD) = -0.78 (95 % CI = -1.0 to -0.56)], comparable intraoperative bleeding [SMD = 0.64 (95 % CI = -1.3-0.0430) P = 0.066] and longer operative time compared to open gastrectomy [1.9 (95 % CI 0.05-3.8) P = 0.045, with P < 0.001]., Conclusion: This study supports the use of laparoscopic-assisted distal gastrectomy for treatment of gastric adenocarcinoma with evidence of comparable, if not better, short-term postoperative parameters when compared to open distal gastrectomy. The long-term oncological outcomes appear similar but may require more evaluation.

This systematic review was undertaken to assess the published evidence for the safety, feasibility and reproducibility of laparoscopic liver resection. A computerized search of the Medline and Embase databases identified 28 non-duplicated studies including 703 patients in whom laparoscopic hepatectomy was attempted. Pooled data were examined for information on the patients, lesions, complications and outcome. The most common procedures were wedge resection (35.1%), segmentectomy (21.7%) and left lateral segmentectomy (20.9%). Formal right hepatectomy constituted less than 4% of the reported resections. The conversion and complication rates were 8.1% and 17.6%, respectively. The mortality rate over all these studies was 0.8% and the median (range) hospital stay 7.8 days (2-15.3 days). Eight case-control studies were analysed and although some identified significant reductions in-hospital stay, time to first ambulation after surgery and blood loss, none showed a reduction in complication or mortality rate for laparoscopically carried out resections. It is clear that certain types of laparoscopic resection are feasible and safe when carried out by appropriately skilled surgeons. Further work is needed to determine whether these conclusions can be generalized to include formal right hepatectomy.
