DUODENAL DUPLICATION CYST - A RARE REASON FOR RELAPSING ACUTE-PANCREATITIS

We report on a 42-year-old male patient who has been treated over a pe riod of five years because of acute relapsing pancreatitis. The diagno ses of viral pancreatitis, pancreatic pseudocyst, and choledochal cyst type III (choledochocele) have been erroneously made. The clinical an d laboratory findings over this period are presented. compare with one another, and analyzed. The correct diagnosis of a duodenal duplicatio n cyst filled with multiple calculi and lying within the lumen of the duodenum could not be established until intraoperative findings and hi stological examinations were completed. The pathogenesis of relapsing acute pancreatitis associated with duodenal duplication cyst filled wi th multiple calculi is proposed, based on the analysis of these findin gs and the literature review.
