Short-term clinical and oncological outcomes after single-incision plus one-port laparoscopic surgery for rectosigmoid cancer: a retrospective clinical analysis of 30 cases

Objective To evaluate the safety and feasibility of single-incision laparoscopic surgery+1 (SILS+1) radical resection of sigmoid and upper rectal cancer. Methods The clinical data of 30 consecutive patients with sigmoid and upper rectal cancer who underwent SILS+1 radical resection between October 2018 and January 2020 in our hospital were retrospectively analyzed. An initial 5-cm periumbilical transverse incision was made. Then, a multiport device was placed in the umbilical incision. Two 10-mm ports were used for laparoscope insertion, and the other two ports were used for laparoscope device insertion. A 12-mm trocar was placed in the right lower abdominal quadrant under laparoscopic view and served as the surgeon’s dominant operating channel. Results All operations were performed successfully without conversion to conventional laparoscopic surgery or open operation. Three patients developed postoperative complications: one patient developed ileus, one developed postoperative bleeding, and one developed wound infection. There were no perioperative deaths. Conclusions The safety and feasibility of SILS+1 radical resection of sigmoid and upper rectal cancer was established by experienced surgeons in our study. However, further studies are needed to demonstrate the advantages of this procedure compared with the benefits of conventional laparoscopic surgery
