title: Techniques of intragastric laparoscopic surgery.
abstract: Benign or pre-cancerous lesions and foreign bodies of the stomach not amendable to endoscopic removal often require extensive surgery to address a process that does not necessitate lymph node sampling or formal gastrectomy. These lesions are particularly difficult to address endoscopically when located at the esophagogastric junction as a retroflexed view is needed. From its first description in 1995, intragastric laparoscopic surgery has evolved with respect to both technological advancements and tactical innovations. Here we report the development of four distinct techniques of laparoscopic intragastric surgery which we have developed over time and applied in 11 patients. These techniques consist of a (1) combined gastroscopic/laparoscopic approach when minimal manipulation of the lesion is needed, (2) multiport resection which provides optimal triangulation and allows for resection of more complex lesions, (3) stapled removal of broad-based lesions, and (4) single access technique with the device placed directly through the abdominal wall into the stomach. The techniques expand the surgeon's armamentarium to address more complex intragastric processes safely, while the typical postoperative benefits of minimal access surgery such as fast recovery time and less pain are preserved. As we gain greater experience with intragastric laparoscopic surgery, this technique holds the promise of becoming a standard surgical technique for benign lesions for which it is oncologically safe to perform a limited resection.
