Accessory sphincterotomy (endoscopic and surgical) in patients with pancreas divisum.

Sixteen patients with the congenital anomaly of pancreas divisum have been treated by enlarging the orifice of the accessory papilla. Attempts to do this at duodenoscopy succeeded in only 5 of 12 patients, and only one had a good clinical result. Sphincteroplasty was performed surgically in seven patients; five had a good or fair result. Most patients with poor results have undergone pancreatic resection. One patient died post-operatively; the remaining 15 divide equally as good (5), fair (5) and poor (5) results at follow-up after periods ranging from 7 months to 5 years. Results appear to be better in patients presenting with recurrent attacks of acute pancreatitis than in those with chronic pain. The preferred management for these patients remains unclear.
