 Recently, ESD(Endoscopic submucosal dissection)has become widely accepted as a standard endoscopic procedure for early stage gastric cancer. But, we often experience difficult cases due to severe scar scarring in the lesion. For such difficult cases, we conducted laparoscopic local resection(full-thickness resection)assisted by endoscopy. In the past, Hiki et al. and Abe et al. reported cases of laparoscopic local resection assisted by endoscopy, but there remained a problem that those procedures might cause peritoneal dissemination by exposing contents of the stomach into the abdominal cavity. We developed a new method which could be done without exposing the gastric content into the abdominal cavity and call it CLEAN-NET' (Combination of Laparoscopic and Endoscopic Approaches to Neoplasia with Non-Exposure Technique). We introduce a summary of the procedure and present the result of 17 cases that we experienced.
