Potential for peritoneal cancer cell seeding in endoscopic full-thickness resection for early gastric cancer

During endoscopic full-thickness resection (EFTR) for cancers, whether exposure of the lumen to the abdominal cavity during the procedure is acceptable is controversial because of the potential risk of tumor cell seeding. To assess the possibility of transplantation due to contact with tumor cells during the procedure, we prospectively investigated the ability of cancer cells to be detached by touching the tumor surface.
