Feasibility of Single-Incision Plus One Port Laparoscopic Low Anterior Resection for Rectal Cancer

Abstract

Purpose: Single-incision laparoscopic surgery is a recently developed minimally invasive surgical technique. We aimed to compare the feasibility and safety of single-incision plus one port laparoscopic low anterior resection (S+1-LAR) with those of multi-port laparoscopic low anterior resection (M-LAR) for mid-to-low rectal cancer. Methods: We retrospectively reviewed patient characteristics and surgical outcomes by assessing data collected from the medical records of patients who underwent elective laparoscopic low anterior resection for mid-to-low rectal cancer at the Gangneung Asan Hospital. Results: From April 2015 to April 2019, 52 patients underwent S+1-LAR (n=28) or M-LAR (n=24) for midto-low rectal cancer at Gangneung Asan Hospital. There were no significant between-group differences in clinical characteristics. The mean postoperative 1-day pain score was significantly lower in the S+1-LAR group. Surgical outcomes and postoperative complications did not differ significantly between the two groups. Conclusion: S+1-LAR is a feasible and safe technique and is comparable with M-LAR in terms of surgical outcomes of patients with mid-to-low rectal cancer.

Single-incision plus one-port laparoscopy surgery versus conventional multi-port laparoscopy surgery for colorectal cancer: a systematic review and meta-analysis

“…Based on SILS, SILS + 1 typically adds a 12-mm trocar needle in the right or left lower abdomen depending on the surgical site. This additional port restores the triangulation of laparoscopic surgery, thereby reducing instrument collisions, improving visibility, and tissue tension [ 38 ]. Additionally, it can serve as an entry point for linear staplers and a channel for drainage tubes [ 35 ].…”
