Meta-analysis of transperitoneal and retroperitoneal laparoscopic decortication in the treatment of simple renal cysts / 国际外科学杂志

ABSTRACT

Objective:To evaluate the clinical effects of transperitoneal and retroperitoneal laparoscopic decortication in the treatment of simple renal cysts.Methods:PubMed, EMBASE, Cochrane Library, CNKI, VIP and WanFang databases were searched, All studies about comparing transperitoneal and retroperitoneal laparoscopic decortication for simple renal cysts were included. The evaluation indicators included operative time, intraoperative blood loss, postoperative drainage time, postoperative hospital stay, and complication rate. Statistical analysis of the data using RevMan 5.3 software.Results:A total of 14 control studies were included, 409 cases in the transperitoneal group and 452 cases in the retroperitoneal group. Meta-analysis demonstrated that compared with the transperitoneal group, the retroperitoneal group had shorter operation time ( MD=8.81, 95% CI: 3.79-13.82, P<0.01), less intraoperative blood loss ( MD=4.89, 95% CI: 1.40-8.38, P<0.01), and shorter postoperative hospital stay ( MD=0.60, 95% CI: 0.24-0.96, P<0.01). However, there were not significant differences between the two approaches in postoperative drainage time ( MD=-0.12, 95% CI: -0.26-0.03, P=0.13) and complication rate ( OR=1.47, 95% CI: 0.48-4.47, P=0.05). Conclusions:Compared with the transperitoneal, the retroperitoneal laparoscopic decortication has the advantages of short operation time, less intraoperative blood loss and short postoperative hospital stay. Therefore, retroperitoneal laparoscopic decortication is expected to be the first choice for the treatment of simple renal cysts.
