Application of pelvic peritoneum reconstuction accompanied with irrigation and negative pressure drainage in robotic abdominoperineal resection for rectal cancer
Abstract：Objective To explore feasibility and efficacy of pelvic peritoneum reconstuction (PPR) accompanied with irrigation and negative pressure drainage after robotic abdominoperineal resection (APR) for rectal cancer. Methods The clinical data of 59 cases of low-rectal cancer patients treated from December 2014 to April 2016 in the First Affiliated Hospital of Nanchang University were analyzed retrospectively. Among all the cases, 31 cases received PPR accompanied with irrigation and negative pressure drainage in robotic APR (closed group) and 28 cases received gravity drainage without PPR (unclosed group). Operative and postoperative details were compared between two groups. Results No conversion occurred in the two groups. The pelvic peritoneum was closed successfully in closed group. There was no significant difference between the two groups in terms of operation time[(186.6 ± 23.0) min vs. (176.9 ± 19.4)min,P=0.088],incidence of perineal hernia[0(0/31) vs. 7.1%(2/28),P=0.221]and incidence of intestinal obstruction[3.2%(1/31) vs. 10.7%(3/28),P=0.337]. Compared with unclosed group,closed group displayed lower incision infection rate [6.5%(2/31) vs. 32.1%(9/28),P=0.011]. The intra-oprerative blood loss,the number of retrieved lymph node,positive circumferential resection margin and time to remove the drainage tube were similar between two groups. One case of tumor recurrence occurred in unclosed group. Conclusion PPR is necessary after robotic APR for rectal cancer,which accompanied with irrigation and negative pressure drainage might significantly reduce incidence of complications.
