Abstract
Purpose This study aimed to evaluate the relationship between the body mass index (BMI) and the short-term outcomes of laparoscopic total gastrectomy (LTG). Subjects and Methods Data of patients who underwent LTG for gastric cancer at six institutions between 2004 and 2018 were retrospectively collected. The patients were classified into three groups: low BMI (<18.5 kg/m2), normal BMI (≥18.5 and <25 kg/m2) and high BMI (≥25 kg/m2). In these patients, clinicopathological variables were analysed using propensity score matching for age, sex, the American Society of Anaesthesiologists physical state, clinical stage, surgical method, D2 lymph node dissection, combined resection of other organs, anastomosis method and jejunal pouch reconstruction. The surgical results and post-operative outcomes were compared among the three groups. Results A total of 82 patients were matched in the analysis of the low BMI and normal BMI groups. There were no differences in operative time (P = 0.693), blood loss (P = 0.150), post-operative complication (P = 0.762) and post-operative hospital stay (P = 0.448). In the analysis of the normal BMI and high BMI groups, 208 patients were matched. There were also no differences in blood loss (P = 0.377), post-operative complication (P = 0.249) and post-operative hospital stay (P = 0.676). However, the operative time was significantly longer in the high BMI group (P = 0.023). Conclusions Despite the association with a longer operative time in the high BMI group, BMI had no significant effect on the surgical outcomes of LTG. LTG could be performed safely regardless of BMI.

Abstract
Background Obesity is a growing epidemic around the world, and obese patients are generally regarded as high risk for surgery compared with normal weight patients. The purpose of this study was to evaluate the influence of obesity on the surgical outcomes of laparoscopic gastrectomy (LG) for gastric cancer. Methods We reviewed data for all patients undergoing LG for gastric cancer at our institute between October 2004 and December 2016. Patients were divided into non-obese and obese groups and the perioperative outcomes were compared. Furthermore, a subgroup analysis was conducted to evaluate which of the two commonly used methods of LG, laparoscopic-assisted gastrectomy (LAG) and totally laparoscopic gastrectomy (TLG), is more suitable for obese patients. Results A total of 1691 patients, 1255 non-obese and 436 obese or overweight patients, underwent LG during the study period. The mean operation time was significantly longer in the obese group than in the non-obese group (209.9 ± 29.7 vs. 227.2 ± 25.7 min, P < 0.01), and intraoperative blood loss was significantly lower in the non-obese group (113.4 ± 34.1 vs. 136.9 ± 36.7 ml, P < 0.01). Time to first flatus, time to oral intake, and postoperative hospital stay were significantly shorter in the non-obese group than in the obese group (3.3 ± 0.8 vs. 3.6 ± 0.9 days; 4.3 ± 1.0 vs. 4.6 ± 1.0 days; and 9.0 ± 2.2 vs. 9.6 ± 2.2 days, respectively; P < 0.01). 119 (9.5%) of the non-obese patients had postoperative complications as compared to 44 (10.1%) of the obese patients (P = 0.71). In the subgroup analysis of all patients, TLG showed improved results for early surgical outcomes compared to LAG, mainly due to its advantages in obese patients. Conclusions Obesity is associated with long operation time, increased blood loss, and slow recovery after laparoscopic gastric resection but does not affect intraoperative security or effectiveness. TLG may have less negative results in obese patients than LAG due to a variety of reasons. Our analysis shows that TLG is more advantageous, with regard to early surgical outcomes, for obese patients.
