  • two cases of portal Annular Pancreas

    Portal Annular Pancreas is one of the pancreatic fusion anomalies in which the uncinate process of the Pancreas extends to fuse with the dorsal Pancreas by encircling the portal vein or superior mesenteric vein. We report two consecutive patients with portal Annular Pancreas. The first case is a 71-year-old male patient who underwent a pancreaticoduodenectomy for intraductal papillary mucinous neoplasm in the head of Pancreas. His preoperative computed tomography scan showed the suprasplenic type portal Annular Pancreas. The second case is a 74-year-old female patient who underwent a laparoscopic anterior radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic body cancer. In operative finding, portal confluence (superior mesenteric vein-splenic vein-portal vein) was encased with the uncinate process of Pancreas in both cases. Therefore, they required pancreatic division at the pancreatic neck portion twice. During the postoperative period, grade B and A, respectively, postoperative pancreatic fistulas occurred and were controlled by conservative management. Surgeons need to know about this rare pancreatic condition prior to surgical intervention to avoid complications, and to provide patients with well-designed, case-specific pancreatic surgery.

  • laparoscopic enucleation of insulinoma in a patient with Annular Pancreas a rare case
    Journal of Gastrointestinal Surgery, 2014
    Co-Authors: Kai Wang, Yupei Zhao, Wenming Wu, Lin Cong, Xiaoping Xing


    Insulinoma and Annular Pancreas are both rare disorders. In this report, we describe a patient who had insulinoma in association with an Annular Pancreas.

  • symptomatic adult Annular Pancreas
    Journal of Clinical Gastroenterology, 2003
    Co-Authors: Yicheng Chen, Jenghwei Tseng


    : Annular Pancreas is most often found in neonates and infants younger than 1 year of age. Annular Pancreas in adults is rare and clinically identifiable when symptomatic. Upper gastrointestinal radiography and surgical confirmation were the most common methods for diagnosing Annular Pancreas in the 1950s to 1980s. However, the revolution in image modalities has enabled preoperative diagnosis in the last 20 years. Many surgical methods have also been developed, and the one used depends on the presentation and extent of the Pancreas annulus. We report two cases of symptomatic adult Annular Pancreas at Chang Gung Memorial Hospital in Taiwan.
