Non-Exposure Endoscopic-Laparoscopic Cooperative Surgery for Stomach Tumors: First Experience from the Czech Republic

Abstract

Laparoscopic wedge resection of the stomach is a widely accepted treatment for primary resectable gastrointestinal stromal tumors (GISTs). However, it is difficult to determine the appropriate incision line from outside of the stomach, and many attempts have been made to avoid unnecessary resection of unaffected gastric tissues. Recently a technique called non-exposed endoscopic wall-inversion surgery (NEWS) was introduced to avoid exposure of GIST to the peritoneum. Here, we describe the first published case of NEWS for GIST of the stomach practiced in Korea. Clin Endosc 2016;49:475-478

Laparoscopy Endoscopy Cooperative Surgery for Inflammatory Fibroid Polyp in the Esophagus

“…In the other two cases, endoscopic mucosal resection (EMR) was performed, but both of them developed local recurrences within a year after EMR (6, 8). To our knowledge, this was the first case of LECS being used to resect esophageal IFP, although it has been attempted in some cases of gastric IFP (13).…”

Comparison of Nonexposed Endoscopic Wall-Inversion Surgery with Endoscopic-Navigated Laparoscopic Wedge Resection for Gastric Submucosal Tumours: Results of a Two-Centre Study

“…Cooperative endoscopic-laparoscopic surgery for the resection of gastric tumours has been performed at the Department of Surgery of the Faculty Hospital Kralovske Vinohrady since January 2016. Our initial experience with these techniques was detailed in a previously published study [5]. The goal of this current study was to compare NEWS with LWR for the treatment of submucosal gastric tumours.…”

Clinical Overview of GIST and Its Latest Management by Endoscopic Resection in Upper GI: A Literature Review

“…This method permits a full-thickness resection without exposing the gastric lumen to the peritoneal space, thus avoiding peritoneal seeding [ 54 ]. The standard procedure includes indicating and injecting a solution into the submucosal layer around the lesion endoscopically, dissecting the seromuscular layer laparoscopically (leaving the mucosa intact), pulling the lesion outwards by sutures placed at the lesion laparoscopically, and achieving complete resection by closing the defect with a laparoscopic stapling device [ 56 ]. Its advantages over the NEWS technique lies in the larger size that can be resected using the CLEAN-NET technique (>4 cm).…”

“…Its advantages over the NEWS technique lies in the larger size that can be resected using the CLEAN-NET technique (>4 cm). The tumor located on the posterior wall can be very challenging when removed endoscopically [ 56 ]. Moreover, this technique is difficult for large intraluminal protrusions, which make it difficult to place the stapling device.…”
