Background: Laparoscopic surgery for gastric cancer has become widely used; minimally invasive surgery has become the mainstream of treatment. This randomized controlled trial (RCT) aimed to compare long-term quality of life (QoL) and weight loss rates in patients who underwent single-port laparoscopic gastrectomy (SLG) or multi-port laparoscopic gastrectomy (MLG) for gastric cancer.

Methods: This single-center RCT compared MLG and SLG in patients with clinical stage I gastric cancer, all of which underwent distal gastrectomy between April 2016 and September 2018. A total of 101 patients were evaluated for eligibility; all were randomized into either the SLG group (n = 50) or MLG group (n = 51). Blood tests, weight measurements, and postoperative questionnaires (DAUGS20, EORTC QLQ-C30, PGSAS-45) were performed at 3, 6, 12, and 36 months after surgery to compare the QoL.

Results: At six months postoperatively, there was a higher trend toward lower weight loss in the SLG group compared with the MLG group. At 1, 3, 6, and 36 months postoperatively, the neutrophil-to-lymphocyte ratio was significantly lower in the SLG group than that in the MLG group. The QoL, as measured using the postoperative questionnaires, was generally comparable. However, some favorable results, such as fewer diarrheas, were achieved.

Conclusions: SLG was partially superior to MLG in terms of long-term QoL, in addition to assurance of esthetics and reduced pain. In addition, systemic inflammatory markers and weight loss rates were lower, suggesting a potential long-term benefit. SLG may be an option for stage I gastric cancer surgery. Further follow-up and multicenter studies should be considered.
