Abstract:

Objective To investigate the safety and feasibility of transumbilical single-incision laparoscopy in radical operation for right colonic cancer. Methods A retrospective study was conducted in 60 patients who underwent laparosco-pic radical right hemicolectomy for colonic cancer from January 2019 to June 2020 in Department of Gastrointestinal Surgery Changshu Second People’s Hospital combined with Department of Surgery Ruijin Hospital Shanghai. The patients were divided into group of single-incision laparoscopic surgery(SILS) (n=30) and group of conventional five-port laparoscopic surgery(CLS) (n=30). Patient demographics, operative details and postoperative complications were compared between two groups. Results No significant differences were observed in length of incision, intraoperative blood loss, largest diameter of tumor, postoperative feeding time, extraction time of drainage tube, postoperative hospital stay, pathologic stage and lymph node harvest between SILS group and CLS group. Compared with CLS group, SILS group showed that all longer operative time [(185.17±12.28) min vs. (127.83±16.70) min], lower mean pain score (visual analog scale) [(3.30±0.79) vs. (3.97±0.72)] on the first postoperative day and earlier postoperative evacuation time [(2.70±0.54) d vs. (3.97±0.49) d)] with statistical significant difference (P<0.05). There were incision infections 2 cases in SILS group and 1 case in CLS group (P>0.05). One case with postoperative anastomotic leakage in both SILS group and CLS group (P>0.05). No tumor recurrence was present in 2 groups during the period of follow-up (11.0±0.6) months. Conclusions Clinical efficacy in single-incision laparoscopy would be similar to CLS for radical resection of right colonic cancer.
