title: A new technique of endoscopic full-thickness resection using a flexible stapler.
abstract: There is a significant need for a safe and easy technique for endoluminal endoscopic resection of gastrointestinal lesions, but such procedures are usually restricted to resection of the mucosal layer in order to preserve the integrity of the wall of the gastrointestinal tract. We present two patients, one with early cancer and one with a carcinoid tumor, who were treated by endoscopic full-thickness resection. We used a stapling device, consisting of a flexible shaft, which was positioned intraluminally, and a remote control. After pilot investigations in pigs and in human anatomical preparations, we performed a full-thickness resection of the gastric wall in these patients, using the flexible stapling device under gastroscopic control. Gastric wall specimens up to 4 cm x 4 cm in size were resected with the use of two to three stapler magazines. Both procedures followed an uneventful course and the patients made an uncomplicated recovery. Further studies are necessary to test the applicability of the technique in the management of other gastric neoplastic lesions.
