Abstract
PURPOSE: This study aimed to evaluate the short- and long-term outcomes in obese patients with gastric cancer undergoing totally laparoscopic total gastrectomy (TLTG) to clarify its feasibility in this population. METHODS: We examined 136 consecutive patients who underwent TLTG for gastric cancer (GC) between 2013 and 2018. A total of 45 patients with a body mass index (BMI) ≥ 25 kg/m2 were defined as the obese group (obese and overweight patients by the WHO classification), and 91 patients with a BMI < 25 kg/m2 were defined as the non-obese group. Short- and long-term outcomes were compared, and the correlation between obesity and postoperative complications was examined in patients who underwent TLTG. RESULTS: Although the operation time (min) was significantly longer in the obese group than in the non-obese group (329 vs 307, p = 0.002), there were no significant differences in the total volume of blood loss (mL) (118 vs 60, p = 0.059) or the rate of conversion to laparotomy between the two groups (2 vs 2, p = 0.466). Moreover, there was no significant difference in the incidence of postoperative complications between the two groups (16% vs 19%, p = 0.653). In the multivariate analysis, obesity was not identified as a risk factor for postoperative complications among patients who underwent TLTG. The rate of overall survival was not significantly different between the groups (p = 0.512). CONCLUSION: TLTG is feasible for obese Japanese patients with GC. To validate the results of the present study, it is necessary to conduct a prospective study of a large population of patients with GC.
