Oc.02.2 laparoscopic-endoscopic cooperative surgery (lecs) for full thickness resection of gastrointestinal stromal tumors (gists)

Aims In Western countries gastric GISTs are treated with laparoscopic wedge resection (LWR). This procedure is technically challenging in some gastric sites, so it’s difficult to achieve minimal and curative resection margins or large resections are needed. In Eastern countries, Laparoscopic Endoscopic Cooperative Surgery (LECS) has been proposed as a new treatment for gastric GISTs. For ulcerated GISTs a modified technique (Non-exposed Endoscopic Wall-inversion Surgery: NEWS) has been developed to avoid peritoneal tumor seeding. This prospective study evaluates the outcomes of these procedures in our center.
