Stenosis of the pancreaticodigestive anastomosis (pancreaticogastrostomy and pancreaticojejunostomy) is a very rare complication that usually develops several years after pancreaticoduodenectomy (PD). Only a few cases have been previously reported. We have reviewed the literature and present 2 more cases of pancreaticojejunostomy stenosis that started with episodes of recurrent acute pancreatitis 6 years and 1 year after PD, respectively. Diagnosis was based on symptoms of pancreatitis (12-15 episodes between 5 and 20 months after PD) and CT and MRI scans. Both patients were treated by resection of the pancreaticojejunostomy stenosis, including a 1-cm slice of pancreatic parenchyma in contact with the jejunum, followed by a new well-vascularized two-layer end-to-side PJ with external drainage of the Wirsung duct. Catheter drainage was exteriorized through a jejunal limb using the Witzel technique. Postsurgical course was uneventful in both cases, and after a follow-up period of 3 and 2.5 years, respectively, the patients remain asymptomatic but with endocrine and exocrine insufficiency. Resection of the PJ and construction of a new PJ with external stent drainage of the Wirsung duct is our preferred surgical option in the rare cases of PJ stenosis after a Whipple procedure.
