Clinical experience in 82 patients with pancreas divisum: preliminary results of manometry and endoscopic therapy

Although it is clear that the majority of patients with pancreas divisum have no clinical disease, there is a subset of patients who have either unexplained abdominal pain or recurrent pancreatitis. Endoscopic therapy of the minor papilla may alter the clinical course of those patients with pancreas divisum and recurrent pancreatitis. Manometric study of the minor papilla is feasible and reveals a sphincter mechanism similar to the major papilla. Clinical response to endoscopic therapy may aid in selecting patients who might benefit from surgical sphincteroplasty. Refinement of manometric study of the minor papilla offers a potential method of detecting functional obstruction of dorsal duct drainage.
