Gastrointestinal Recovery and Outcome after Laparoscopy-assisted versus Conventional Open Distal Gastrectomy for Early Gastric Cancer

Abstract

Laparoscopy-assisted gastrectomy has been increasingly reported as the treatment of choice for early gastric cancer. However, there is little information regarding the benefits of laparoscopy-assisted distal gastrectomy (LADG). LADG and conventional open distal gastrectomy (DG) for early gastric cancer were compared in terms of operative outcome, recovery of bowel function, complications, and changes in body weight. Thirty-four patients underwent LADG for early gastric cancer. These patients were compared with 31 patients who underwent DG during the same period. For estimating gastrointestinal motility recovery, 20 radiopaque markers were inserted into the duodenum during surgery, and abdominal X-rays were taken daily until all markers were seen in the ascending colon. Age, gender, and histologic differentiation of the lesions were matched. The LADG group required a significantly longer operative time and the dissection of fewer lymph nodes. Postoperative hospital stay and the occurrence of postoperative complications (ileus) were significantly shorter and less frequent in the LADG group. The LADG group showed a more rapid recovery of gastrointestinal motor function compared with the DG group during the early postoperative period. Body weight 24 months after LADG was about 100% of pre-illness weight, but no further weight change was encountered in the DG group. For selected patients with early gastric cancer, LADG with lymphadenectomy can provide a rapid recovery and good quality of life without compromising the cure rate.
