Long-term outcomes of percutaneous endoscopic intragastric surgery in the treatment of gastrointestinal stromal tumors at the esophagogastric junction

Abstract

As far as the short- and long-term outcomes of our experience are reviewed, PEIGS seems as curative as other aggressive resection methods such as proximal gastrectomy. Tumor enucleation by PEIGS, offering a chance to preserve the stomach, can be a preferable option in carefully selected patients with EGJ GISTs, when performed by a skilled surgeon.

Endoscopic trans gastric assisted surgery for gastric tumors: Case report and description of a new surgical technique

“…Percutaneous endoscopic intragastric surgery [PEIGS] reported by Kanehira et al [4], performing laparoscopic intragastric surgery with several trocars to treat gastric GIST, showed En-bloc enucleation, negative margins without tumor rupture in all patients with an average operation time of 172.3 min compared to our case with 58 min. 3 postoperative complications [one localized peritonitis, one bleeding, and one surgical site infection].…”

Needlescopic intragastric surgery facilitated by newly developed 2mm instruments

“…We have reported satisfactory short-and longterm clinical outcomes of PEIGS to justify this operation from the oncological point of view (12). Our next aim was to further improve PEIGS by using needlescopic instruments, which should be hypothetically associated with less pain and less risk of incisional hernia compared with single-incision intragastric surgery.…”

Percutaneous endoscopic intragastric surgery: an organ preserving approach to submucosal tumors at esophagogastric junction

“…Our previous publication also demonstrated convincing clinical results from PEIGS for large tumors (max. 8 cm), and thus suggested submucosal tumors >5 cm can be treated by PEIGS, when it is carefully performed by experienced laparoendoscopic surgeon (6).…”

“…In order to preserve the entire stomach of the patients with a tumor at EGJ the authors have been performing percutaneous endoscopic intragastric surgery (PEIGS) since 1993 and have reported its fair outcomes (4)(5)(6)(7). Moreover, in addition to the original method of PEIGS, we have recently developed further cosmetic procedures such as single incision PEIGS (5,6) and needlescopic PEIGS (7). Herein we demonstrate the techniques of the three different types of PEIGS, which should play an important role as an organ preserving surgery in the treatment of gastric submucosal tumors.…”
