title: Pancreatitis and pancreas divisum: aetiological and surgical considerations.
abstract: It has been suggested that acute pancreatitis occurs more commonly in patients with pancreas divisum and that these patients may respond to surgery aimed at improving pancreatic ductal drainage. We have studied the incidence of pancreas divisum in patients referred for endoscopic retrograde cholangio pancreatography (ERCP) and the results of surgical sphincteroplasty in a separate series of such patients. Twenty-three patients with pancreas divisum were identified among 336 successful pancreatograms (Group A), an incidence of 6.8%. The incidence of pancreas divisum in patients having ERCP for documented pancreatitis was 13% (11 of 86) compared with 4.8% (12 of 250) in those having ERCP for other indications. This difference was statistically significant (P less than 0.05). However, pancreas divisum was not the sole risk factor for pancreatitis in the majority of our patients; most also had one of the commonly recognized causes for their pancreatitis. There is dispute about the indications for surgery in patients with recurrent acute pancreatitis and pancreas divisum, but without any other risk factor. We have reviewed the results of operations on 13 patients with pancreas divisum (Group B) treated in four different hospitals. Surgical sphincteroplasty was carried out on 10 patients with documented pancreatitis and seven of these had good results. Three patients who had operations for pain without documented pancreatitis were not improved.
