Pancreas divisum--advocates and agnostics.

Pancreas divisum is discussed to define and evaluate criteria for treatment. Selecting candidates for surgery is imprecise since the anatomic anomaly is so prevalent. Endoscopic stenting has been utilized as a therapeutic and diagnostic test. Appraisals of operative results vary depending on length and detail of follow-up. Sphincteroplasty of the dorsal segment is the procedure of choice when the gland is normal--but resection and caudal drainage each have a role, depending on the anatomic and endoscopic findings.
