Calcifications within the duct of Wirsung in calcific pancreatitis

A review of abdominal radiographs of 50 patients with the clinical diagnosis of chronic pancreatitis showed calcific pancreatitis in 27 patients. Ten patients had severe pain associated with weight loss. Five had obstruction of the duct of Wirsung: one by a pseudocyst and four by large stones near the ampulla of Vater. The radiologic workup presented emphasizes the need to study the duct of Wirsung in patients with chronic pancreatitis to guide the surgical approach for relief of intractavle pain. Theories regarding the pathophysiology of calcium deposition and stone formation and migration are reviewed.
