An innovative procedure of laparoscope combined with endoscopy for gastrointestinal stromal tumor resection and cholecystectomy: A case report and literature review.

The present study reports a novel approach to laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor (GIST) resection and cholecystectomy, and conducts a review of the associated literature. The novel surgical procedure was performed on one patient who was diagnosed with a GIST and cholecystic polypus. The GIST was resected using an insulation-tipped diathermic electrosurgical knife under the guide of an endoscope. Subsequently, a cholecystectomy was performed by inserting two more 5-mm trocars and instruments transumbilically, guided using an endoscope. The tumor and the gallbladder were exteriorized using a peroral approach and the incision lining of the stomach was sutured laparoscopically. The procedure was successfully performed and the patient experienced no discomfort during the 5-year follow-up. In conclusion, the present study demonstrates that laparoscopic and endoscopic cooperative surgery is feasible and would be an ideal choice for invisible abdominal scar surgery, in particular for multi-visceral resection.
