Comparison of hand-assisted laparoscopic and open radical distal gastrectomy for obese patients.

To evaluate the feasibility and safety of hand-assisted laparoscopic surgery for gastric cancer in obese patients, we compare the operative outcomes in obese patients who underwent hand-assisted laparoscopic distal gastrectomy (HALDG) and open distal gastrectomy (ODG). One hundred sixty-two obese patients with gastric cancer operated on in our department from January 2009 to December 2011 were divided into two groups: the open distal gastrectomy group (the ODG group) and the hand-assisted laparoscopic distal gastrectomy group (the HALDG group). Operative time, estimated blood loss, number of lymph node retrieval, wound length, times of analgesic injection, time to the first flatus, and postoperative hospital stay were compared between the two groups. Estimated blood loss, wound length, times of analgesic injection, time to the first flatus, and postoperative hospital stay were significantly less or shorter in the HALDG group than in the ODG group. There were no significant differences in tumor size, retrieved lymph nodes, American Joint Cancer Committee /Union Internationale Contre le Cancer staging, and resection margins between the two groups. Obesity should not be seen as a contraindication for HALDG. HALDG for obese patients is a safe, feasible, and oncologically sound procedure and has advantages over ODG.
