The feasibility of laparoscopic extended pelvic surgery for rectal cancer.

Abstract

The present study aimed to assess the safety and feasibility of laparoscopic extended pelvic surgery for primary or recurrent rectal cancer. The data on 77 patients, who underwent extended pelvic surgery between February 2008 and June 2014, were retrospectively analyzed. The patients were divided, based on their treatment history, into an open surgery (OS) group (n=41) and a laparoscopic surgery (LS) group (n=36). The operative time in the LS group was significantly longer than that in the OS group (766 vs. 561min; p<0.001). In contrast, the LS group was associated with a significantly lower volume of intraoperative blood loss (195 vs. 923ml; p<0.001), fluid balance (5.38 vs. 8.23ml/kg/h; p<0.001) and rate of complications (40.0 vs. 68.3%; p=0.035), and a significantly shorter postoperative hospital stay. The postoperative levels of colloid osmotic pressure and albumin were significantly higher in the LS group. The operative time of the LS group was longer than that of the OS group; however, the LS group experienced less blood loss and fewer complications. Moreover, LS was associated with a reduction in intraoperative infusions and a reduced fluid balance, which maintained homeostasis.
