Pancreas Divisum and Pancreatitis: a Coincidental Association?

Summary

The aim of the present study is to assess the frequency of pancreas divisum and the features of patients with pancreas divisum in order to assess the role of this anomaly in the occurrence of pancreatitis. A total of 1049 endoscopic retrograde pancreatographics were studied between 1978 and 1988. Patients with pancreas divisum were studied in terms of their clinical findings and their disease (pancreatitis or not). Pancreas divisum was diagnosed in 62 patients (5.9 %). No statistical differences with regard to age and sex were found between patients with and without pancreas divisum. The frequency of pancreas divisum was similar in the different groups of disease, especially chronic pancreatitis, acute pancreatitis, recurrent pancreatitis and idiopathic pancreatitis. The study of pancreatograms showed that dorsal ductal abnormalities alone were found as frequently as ventral alterations alone. Our results show that pancreas divisum cannot be directly implicated in the occurrence of pancreatitis, and should not prompt a systematic sphincterotomy of the accessory papilla. This treatment should only be considered in the rare cases of acute recurrent idiopathic pancreatitis with dorsal ductal dilatation and stenosis of the accessory papilla.
