Background
Conventional open gastrectomy has been reported to result in increased morbidity in obese patients. To date, there has been no study evaluating laparoscopic gastrectomy in such patients; therefore, we assessed the short-term results of this procedure in a group of obese patients.
Methods
The study included 99 consecutive patients who underwent laparoscopy-assisted distal gastrectomy (LDG) for the cure of early gastric cancer. The patients were divided into two groups: obese (body mass index [BMI] ≥25.0, n = 16) and nonobese (BMI <25.0, n = 83). Patient characteristics, operative details, and postoperative outcomes were compared and analyzed.
Results
Patient characteristics, including age, sex, American Society of Anesthesiologists (ASA) status, and disease stage, were not different between obese and nonobese patients. Operating time was significantly longer in obese patients than in nonobese patients (271 vs 239 min, p < 0.05). However, there was no significant difference between obese and nonobese patients in time to first flatus (3.7 vs 3.3 days), time to solid diet (6.3 vs 5.2 days), length of postoperative hospital stay (18.7 vs 17.9 days), or frequency of major (25% vs 16%) and minor (19% vs 12%) postoperative complications. There were no conversions to conventional open surgery and no perioperative deaths.
Conclusion
The only difference between our two study groups was that LDG required a longer operating time in obese patients; morbidity and length of hospital stay were not increased. Thus, we believe that LDG is likely to become the treatment of choice for obese patients with early gastric cancer.
