title: Laparoscopy-assisted distal gastrectomy for overweight patients in the Asian population.
abstract: OBJECTIVE
  It is generally considered difficult to operate on overweight patients, who are also at increased risk of postoperative complications. We conducted this study to clarify the technical feasibility and postoperative outcomes of laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer (EGC) in overweight patients.
  
  
  METHODS
  Between July 2004 and December 2006, 116 patients with preoperatively diagnosed EGC underwent LADG at our department. We classified these patients into two groups based on body mass index (BMI). There were 60 patients in the high-BMI (> or =23 kg/m2) group and 56 in the low-BMI (<23 kg/m2) group. The clinicopathologic features, postoperative outcomes, and operation-related morbidities were compared.
  
  
  RESULTS
  None of the patients needed conversion to laparotomy. There were no notable differences in clinical characteristics or histologic features between the groups. Although the operation time was significantly longer in the high-BMI group, there were no significant differences in postoperative bowel recovery, postoperative hospital stay, or operation-related morbidities.
  
  
  CONCLUSIONS
  Laparoscopy-assisted distal gastrectomy for overweight patients is feasible and safe; however, because of its technical difficulties and the complexities of lymph node dissection, it should be carefully considered, and may only be suitable for early-stage cancers.
