[A Case of Laparoscopic Whole Layer Cholecystectomy for Elevated Lesion Suspected Biliary Cancer].

A case of attempted laparoscopic cholecystectomy for elevated lesion which was clearly early biliary cancer. Laparoscopic cholecystectomy has become popular as a minimally invasive surgical method, and is the primary choice for benign diseases. However for cases of suspected biliary cancer, open cholecystectomy, rather than laparoscopic, is recommended according to medical guidelines. The reason for this is that in cases of damage to the gallbladder, bile spillage to the abdominal cavity may occur, leading to port site recurrence and peritoneal recurrence. In addition, for invasion depth exceeding ss, or in cases of RAS cancer, the cancer may become exposed on the resected surface and remain. Hypothetically though, if the gallbladder is resected by total layer resection, RAS cancer can be removed. At this time, we performed a laparoscopic whole layer cholecystectomy for elevated lesion. We would like to report this case along with some bibliographic considerations.
