Pancreas Divisum

Pancreas divisum is the most common congenital anomaly of the pancreas, occurring in approximately 5-10% of the population. Failure of the dorsal and ventral pancreatic primordia to fuse may result in separate draining of the ducts of Wirsung and Santorini (Figs. 2-52 and 2-53). Perhaps 25% of these develop pancreatitis secondary to stenosis or obstruction of one or both ducts,

A 62-year-old woman presented with abdominal pain.

(a) Enhanced CT shows an aneurysmal dilatation (A) originating from and protruding anteriorly to the main portal vein (PV). Asterisk = contrast medium in colon.

(b) Transarterial portography reveals an aneurysmal dilatation of the portal vein (A) with a diameter of 30 mm.

A 12-year-old female presented with shock and intraperitoneal bloody ascites.

(a and b) Enhanced CT shows a large hepatic tumor (arrows) with subcapsular hematoma and bloody ascites (open arrows). A small superior mesenteric vein (curved arrow) empties into the porta hepatis without opacification of the portal vein (PV) and intrahepatic branches (arrowheads). An enlarged left renal vein and IVC are noted. (c) Transarterial portography reveals hypogenesis of the portal vein (arrows) and collateral circulation of mesenteric blood flow to the IVC via mesenteric-gonadal venous anastomosis (curved arrows). Autopsy proved ruptured hepatocellular carcinoma.

and recently, endoscopic therapy has been developed for symptomatic patients.93-95 The pancreatitis is usually limited to the dorsal anlage due to the small orifice of the duct of Santorini.96-97 MR cholangiopancreatogra-phy may be useful for demonstrating pancreas divisum and anomalous pancreaticobiliary duct union.98

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
