Objective：To evaluate the indications，safety and feasibility of endoscopy combined with laparoscopy in the treatment of gastrointestinal (GI) tumors.
Methods：The clinical data of 30 patients who underwent endoscopy-directed laparoscopic resection of GI tumors from September 2007 to July 2010 were retrospectively studied. Among these tumors,2 were gastric stromal tumor，20 were colorectal adenoma,and 8 were proved to be polyp with cancerous change.
Results：Thirty patients were treated successfully and no patient was converted to laparotomy.The mean time of operation was 40～90 min,blood loss ranged from 20 mL to 50 mL, and the time of rcturn of bowel function was 1～2 days.No complication such as hemorrhage, anastomotic stomal leak, infection of incisional wound or infection of abdominal cavity occurred. postoperative hospital stay was 4 to 6 days.Follow-up of the 30 cases for 6-24 months after operation showed that no recurrence occurred.
Conclusions：Gastroenteric tumor resection by endoscopy combined with laparoscopy demonstrates its advantages such as precise tumor localization, safety,mini-trauma, few complications and quick recovery, and its widespread use is recommended.
