We evaluated the effectiveness of minimal invasive surgery for pancreatic tumors treated in our institution. Minimal invasive surgery was intended to effectively preserve pancreatic and digestive functions with resection of entire tumors without recurrence. During the application of this procedure for pancreatic tumors with no lymph node metastasis, we carefully evaluated whether the tumors were restricted to within the pancreas or were resectable with a small amout of extrapancreatic tissue adjacent to the lesion. Pathological diagnosis indicated that pancreatic tumors treated with this method were mostly limited to flat type mucin-producing tumors. adenomas, insulinomas and solid cystic tumors. Intraductal papillary adenocarcinomas and carcinomas in situ were able to be treated with minimal invasive surgery, where the tumors had no extrapancretic invasion or metastasis. There are several options of surgical procedure for pancreatic tumors. partial pancreatectomy with preservation of the duodenum is sometimes indicated for tumors located in the pancreatic head. Minimal invasive surgery is also expected to be a useful option in the future.
