Ventral pancreatic resection for adenoma and low-grade malignancies of the head of the pancreas

The head of the pancreas ran be anatomically divided into two sections, one drained by the duct of the Santorini system, and the other drained by the ventral pancreatic duct. This study was undertaken to determine whether independent resection of the ventral pancreas drained by the ventral pancreatic duct could be performed safely and effectively, by employing the following method in four patients. First, the duodenum and pancreas mere sufficiently separated preserving the mesoduodenum and the posterior pancreaticoduodenal artery. Next, the main pancreatic duct was divided at the papillary portion, and sectioned at its junction with the duct of Santorini, ensuring preservation of the intrapancreatic bile duct. After the ventral pancreas had been detached from the glistening intrapancreatic bile duct, the ventral pancreas was connected,vith the dorsal pancreas by only the pancreatic parenchyma. The ventral pancreatic resection was completed following the incision of this border, A pancreatic fistula developed in one patient postoperatively, but this healed within 30 days. The hospital stay after surgery ranged hom 35 to 58 days, and a good quality of life was maintained in all four patients, Thus, we conclude that ventral pancreatic resection ran be safely performed and is especially valuable for treating the increasingly frequent adenomas and borderline malignancies in the main pancreatic duct system of the head of the pancreas.
