| [ Summary ] | Laparoscopic wedge resections were used for local resection of gastric submucosal tumors. Recently, laparoscopy and endoscopy cooperative surgery (LECS) have been used for submucosal tumor resection regardless of tumor location or size. LECS procedures can be performed safely with reasonable operation times and adequate cut lines. Non‒exposed endoscopic wall‒inversion (NEWS) and CLEAN‒NET have been used as new procedures. They were carried out using laparoscopy and endoscopy without perforating the stomach to avoid tumor seeding. These LECS procedures are applicable for submucosal tumor resection such as gastrointestinal stromal tumors (GIST) and may be applicable for gastric cancer treatment. We must select the most appropriate procedure in terms of tumor characteristics, including location, shape or size. The cooperation of surgeons and endoscopists is required for implementation and development of LECS procedures. | |
