Purpose: Through evaluating hand assistant laparoscopic D2 radical gastrectomy, the methods of laparoscopic technique to cure gastric cancer are to be expanded. Methods: 21 cases of gastric cancer in General Hospital of Chengdu Military Region between Nov. 2010 and Apr. 2011, which underwent successfully by hand assistant laparoscopic D2 radical gastrectomy (HAL group) were reviewed and analyzed. 25 patients' clinical data (LAT group) (operated by the same surgeon by laparoscopic assistant

... ique) were collected. An analysis was taken between the two groups. Result: Mean laparoscopic operating time of HAL group and LAT group was 44 min (18 -58 min) and 91 min (70 -100 min) respectively. Length of incision was 6.8 cm (6 -7 cm) and 6.1 cm (5 -8 cm) respectively. The mean blood loss was 225 ml (80 -600) and 250 ml (100 -500 ml) respectively. Postoperative complications: One case of gastric atony was found in hand assistant group, and two cases were found in laparoscopic group. One wound infection was found in laparoscopic group. Conclusions: Hand assistant laparoscopic D2 radical gastrectomy can shorten the laparoscopic operating time and reduce the degree of difficulty of the laparoscopic operation, which is easy to popularize. Thus it can be an alternative laparoscopic technique. The further research is needed.
