Laparoscopy-assisted endoscopic removal of a stromal-cell tumor of the stomach.

Endoscopic resection of gastrointestinal tumors is being performed with increased frequency. Submucosal mass lesions pose a particular problem, because of the risk of malignancy and the risk of complications associated with endoscopic removal. Increased incidences of both perforation and bleeding have been reported. We report here on a case in which we used a combined approach that included gastrointestinal endoscopy, laparoscopy, and laparoscopic ultrasound to resect a gastric leiomyoma. We consider that this approach enhanced our diagnostic capabilities, provided intraoperative options for resection, and enhanced the safety of the procedure.
