Open distal gastrectomy versus laparoscopic distal gastrectomy for early gastric cancer: a retrospective study

BackgroundLaparoscopic distal gastrectomy (LDG) is gaining popularity because its early postoperative effect has been shown to be better than open distal gastrectomy (ODG). However, to our knowledge, there are no studies demonstrating ODG is oncologically equivalent to LDG.MethodsThis is a retrospective study based on the prospectively maintained database of the People’s Hospital of Jinan City. Patients with operable, pathologically confirmed early-stage gastric cancer were included, while those with advanced disease or carcinoma in situ were excluded. Extracted data included age, body mass index (BMI), sex, clinical TNM stage, and pathologic stage. The primary outcome was 5-year overall survival, and the secondary outcomes included cancer-specific survival, cost-effectiveness, and quality of life.ResultsA total of 126 patients were finally enrolled and included 61 in the ODG group and 65 in the LDG group. Baseline clinical and pathological characteristics were generally balanced between the two groups. After a median follow-up of 8.31 years, the 5-year overall survival rate was estimated to be 82.8% (95% CI: 69.4–90.7%) for the ODG group and 86.7% (95% CI: 73.9–93.5%) for the LDG group and the recurrence patterns were similar between the two groups.ConclusionsOur data showed that the surgical results of both approaches are satisfactory, and LDG offers a reasonable option to ODG in patients with early gastric cancer.
