In this study, single-port laparoscopic gastrectomy showed better short-term results in terms of less severe pain and may be suitable for the treatment of cStage I gastric cancer.
Objective This prospective randomized trial compared the invasiveness of laparoscopic gastrectomy using a single-port approach with that of a conventional multi-port approach in the treatment of gastric cancer. Summary Background Data The benefit of single-port laparoscopic gastrectomy (SLG) over multi-port laparoscopic gastrectomy (MLG) has yet to be confirmed in a well-designed study. Methods One hundred and one patients who were scheduled to undergo laparoscopic distal gastrectomy for histologically confirmed clinical stage I gastric cancer between April 2016 and September 2018 were randomly allocated to SLG (n = 50) or MLG (n = 51). The primary endpoints were the postoperative visual analog scale pain scores. Secondary endpoints were frequency of use of analgesia, short-term outcomes, such as operating time, intraoperative blood loss, inflammatory reactions, postoperative morbidity, and 90-day mortality. Results The postoperative pain score was significantly lower in the SLG group than in the MLG group (p < 0.001) on the operative day and the postoperative day 1-7. Analgesics were administered significantly less often in the SLG group than in the MLG group (1 vs. 3 days,p = 0.0078) and the duration of use of analgesics was significantly shorter in the SLG group (2 vs. 3 days,p = 0.0171). The operating time was significantly shorter in the SLG group than in the MLG group (169 vs. 182 min,p = 0.0399). Other surgical outcomes were comparable between the study groups. Conclusions SLG was shown to be safe and feasible in the treatment of gastric cancer with better short-term results in terms of less severe pain and may be suitable for treatment of cStage I gastric cancer.
