[Pancreas divisum, chronic pancreatitis and diabetes mellitus. Improvement by pancreaticojejunostomy].

The relationship between pancreas divisum and chronic pancreatitis is controversial. We report the cases of two patients aged 40 and 53 years suffering from recurrent pancreatitis and known to have histologically proven idiopathic chronic pancreatitis. One patient had insulin dependent diabetes. Pancreatography demonstrated in these two cases a pancreas divisum with a dilated dorsal pancreatic duct. A pancreatico-jejunostomy was performed, associated in one case with splenopancreatectomy for pseudo-cyst. With a follow-up of 32 and 78 months, both patients were free of symptoms and the diabetic patient had normal blood glucose levels with diet alone. The clinical history of the patients suggests a relationship between pancreas divisum and chronic pancreatitis and that pancreatico-jejunostomy may improve pancreatic pain and pancreatic function.
