Transoral extraction of a laparoscopically resected large gastric GIST.

Although natural orifice specimen extraction is now widely performed, there have been no reports of transoral extraction following laparoscopic gastric resection. This report describes the first transoral specimen extraction in a patient with a gastrointestinal stromal tumor (GIST) of the lesser curvature of the stomach. The clinical data of a patient with a large gastric GIST were reviewed. Totally laparoscopic resection of the gastric lesser curvature was performed using four trocars. The specimen, put in a retrieval bag, was withdrawn via the transgastric and esophageal route. Reconstruction of the stomach was performed using the intracorporeal technique. The procedure was successfully accomplished without intraoperative and postoperative complications. In conclusion, transoral specimen extraction after laparoscopic gastric resection is a safe and feasible operative procedure for selected patients with a large benign gastric tumor.
