Objective To evaluate the efficacy of laparoscopic-assisted resection of the small bowel for stromal tumors.Methods From January 2003 to May 2007,laparoscopic abdominal exploration was carried out under general anesthesia on 10 patients with space occupying lesion and 5 patients with abdominal pain and hemafecia of unknown origin.After an intestinal lesion was found,a small incision was made at the proper site on the abdominal wall according to the location of the lesion.The diseased intestine was resected outside the abdominal cavity,and then end-to-end anastomosis was performed.Pneumoperitoneum was rebuilt after closing the abdominal cavity in order to observe the blood circulation of the small bowel and intra-abdominal hemorrhage.Results The operation was completed in all the 15 cases.The postoperative pathological examination showed stromal tumors with CD117 positive in 14 cases(93%)and CD34 positive in 9(60%).Three(20%)of the patients were at very low risk,5(33%)at low risk,4(27%)at moderate risk,and 3(20%)at high risk.The mean diameter of the tumors was(2.44?0.63)cm(ranged from 1.5 to 3.6).The operation time was 38 to 72 minutes with a mean of(57.8?10.4),and mean blood loss was(20.1?6.5)ml(10 to 30).The patients were discharged 4 to 7 days after the operation [mean,(5.3?1.1)days],and were followed up for 5 to 36 months [mean,(24.3?8.4)months].No patient had postoperative complications or recurrence in this series.Conclusion Laparoscopy is effective for resection of small bowel stromal tumors.
