Background: Although it has been more than ten years since its first introduction, single-incision distal gastrectomy (SIDG) still lacks solid evidence and there are also no reports on patient quality of life (QOL). This study evaluates the postoperative outcomes and patient QOL of SIDG compared to multiport laparoscopic distal gastrectomy (MLDG).
Methods: This study was designed as a prospective phase II randomized controlled study. Patients diagnosed with early gastric cancer in the distal 2/3rd of the stomach were randomized to either multiport or single-port group. Primary endpoint was pain using the visual analogue scale on postoperative day (POD) 1. Other outcomes include operative data, complications, and patient QOL using the EORTC C30 and STO22 modules.
Results: A total of 43 patients in the SIDG group and 40 patients in the MLDG group were enrolled from September 2017 to February 2020. Mean operation time was 154.3 ± 53.3 min in the MLDG group and 148.9 ± 50.1 min in the SIDG group (p = 0.631). There was no difference in POD1 pain scores between the two groups (MLDG = 4.0 ± 1.3, SIDG = 4.3 ± 1.3, p = 0.372). Mean hospital stay was 5.5 (range 4-12) days in the MLDG group and 5 (range 4-17) days in the SIDG group (p = 0.993). There was no statistical significance in postoperative QOL scores.
Conclusion: Unlike previous reports, there was no difference in POD1 pain scores between SIDG and MLDG. Nevertheless, SIDG did not increase short-term morbidity compared to MLDG and had similar outcomes in QOL.
