Laparoscopic pancreatic surgery: its indications and techniques: from the viewpoint of limiting the indications.

Indications in the field of pancreatic surgery should be limited considering the technical difficulties and the characteristics of pancreatic diseases. Benign or low-grade malignant tumors, including pseudocysts, islet tumors, and cystic tumors, are indications for distal pancreatectomy. Islet tumors such as insulinomas are good candidates for this procedure when they are located near splenic vessels or the main pancreatic duct and enucleation is considered inappropriate. Techniques of laparoscopic distal pancreatectomy with/without splenectomy and laparoscopy-assisted distal pancreatectomy indicated in low-grade malignant tumors such as mucinous cystadenoma are described. Insulinoma is one of the best candidates for enucleation because many of the cases are solitary and benign. The technique of enucleation is also described.
