Journal of Gastrointestinal Surgery Aims and scope

Abstract

Objective

The aim of this study was to compare outcomes between laparoscopy-assisted distal gastrectomy (LADG) and open distal gastrectomy (ODG) in obese and non-obese patients.

Methods

Subjects comprised 248 consecutive patients who underwent distal gastrectomy for gastric cancer between January 1999 and December 2005. Patients with body mass index (BMI) ≥ 25 kg/m2 were defined as obese, and patients with BMI < 25 kg/m2 were defined as non-obese. Parameters analyzed included patients characteristics, tumor characteristics, operative details, postoperative outcomes, and prognosis.

Results

For LADG, 35 patients were considered obese, and 106 patients were non-obese. For ODG, 25 patients were considered obese, and 82 patients were non-obese. Mean operative times in each procedure were significantly longer for the obese group than for the non-obese group (ODG: 241.4 min vs. 199.5 min, p < 0.0001; LADG: 279.6 min vs. 255.3 min, p = 0.03). Blood loss was significantly higher for the obese group than for the non-obese group in ODG (300 ml vs. 400 ml, p = 0.024), but no significant differences were observed between obese and non-obese groups for LADG. Incidence of major postoperative complications, number of retrieved lymph nodes, and disease-free survival rates were similar in obese and non-obese groups for each procedure.

Conclusions

Our analysis revealed that LADG can be safely performed in obese patients, with complication rates and operation outcomes similar to those for non-obese patients.
