title: A new technique for laparoscopic resection of a submucosal tumor on the posterior wall of the gastric fundus.
abstract: Several reports have been published which describe the technique of using an Endo GIA to resect submucosal tumors on the anterior wall of the stomach. Lesions on the posterior wall, however, especially near the esophagocardiac junction (ECJ), are difficult to resect using these reported techniques. This is because the surgeon must divide the omentum and enter the omental bursa in order to use a similar extraluminal technique. Furthermore, special care must be taken to ensure that resections do not involve the ECJ and narrow the esophagus. In order to overcome these difficulties, we have proposed a new technique for the laparoscopic excision of a submucosal tumor located on the posterior wall of the gastric fundus. The principle of this procedure involves the intraluminal resection of the submucosal tumor, including the surrounding stomach wall, using the Endo GIA. This technique is safe, simple, and effective. We believe that we are the first to address the excision of a submucosal lesion by resecting the full thickness of the posterior gastric wall lesion intraluminally.
