Comparison of laparoscopically assisted and open radical distal gastrectomy with extended lymphadenectomy for gastric cancer management

Background: The feasibility and safety of laparoscopically assisted gastrectomy with extended lymphadenectomy for advanced gastric cancer has rarely been studied. This study aimed to investigate the feasibility, safety, and cancer clearance of laparoscopically assisted distal gastrectomy with D2 lymphadenectomy. Methods: Of the 44 patients with distal gastric cancer who underwent radical distal gastrectomy from March 2004 to May 2005, 35 were treated with D2/D2(+) lymphadenectomy. These patients were compared with 58 patients who, during the same period, underwent a conventional open radical distal gastrectomy. Results: The mean total number of retrieved lymph nodes (30.11 +/- 16.97) and the mean tumor margin were comparable with those in the open group. The mean operative time for laparoscopically assisted distal gastrectomy was significantly longer than for open surgery (282.84 +/- 32.81 min vs 223.75 +/- 23.25 min). The patients in the laparoscopic surgery group had less blood loss, shorter times of analgesic injection, and a faster recovery. The rates of complications were comparable between two groups. Conclusions: Although laparoscopically assisted radical gastrectomy with D2 lymphadenectomy is more time consuming than open surgery, it is a safe, feasible procedure that achieves cancer clearance similar to open surgery and leads to a quick postoperative recovery.
