Abdominoperineal resection in the prone position: early outcomes at a tertiary institution in the Western Cape, South Africa

Abstract

Background Extra-levator abdominoperineal resection (ELAPE) performed in the prone jack-knife position is a new technique in the developing world. Literature on the outcomes of ELAPE in a developing country context is scarce. The objective was to assess early outcomes after ELAPE in the prone jack-knife position, and to compare outcomes of patients who underwent the abdominal part of the procedure performed laparoscopically with an open group, at a tertiary institution in Cape Town. Methods Records of patients who underwent ELAPE for rectal adenocarcinoma from February 2011 to February 2017 at Tygerberg Hospital were retrospectively reviewed. Variables of interest included staging, rate of circumferential resection margin involvement (CRMI), intraoperative tumour perforation (IOP), perineal wound complications, early postoperative morbidity, length of intensive care unit (ICU) stay, duration of postoperative hospital stay and 30-day mortality rate. Results 52 patients (median age: 59 years) were included in the analysis. CRMI was evident in 16% (8/49) of patients and IOP in 6% (3/52). Perineal wound complications occurred in 32% (16/50) of patients. Median length of ICU and postoperative hospital stay was 3 days and 7 days, respectively. Overall morbidity was 47% (24/51) and the 30-day mortality rate was 3% (2/52). A significant difference in length of hospital stay was evident between the open and laparoscopic groups (11.5 days vs 6 days). Conclusion Prone abdominoperineal resection (APR), ELAPE, and laparoscopic ELAPE are acceptable and feasible procedures for patients with rectal cancer in the developing world, with outcomes being comparable to those determined in the developed world.
