title: Sump syndrome: endoscopic treatment and late recurrence.
abstract: OBJECTIVE
  Biliary sump syndrome is a rare complication of biliary-enteric anastomosis. Classically, the distal bile duct becomes obstructed by food, stones, or debris after choledochoenterostomy. Endoscopic sphincterotomy has been recommended as the primary and definitive treatment modality. The aim of our study was to confirm the short and long term therapeutic efficacy of endoscopic treatment in a long follow-up period.
  
  
  METHODS
  The series include 31 patients with characteristic clinical illness after choledochoduodenostomy. All of them were successfully treated by endoscopic sphincterotomy and bile duct clearance with a balloon catheter or basket. The follow-up period ranged from 18 to 84 months (median: 51 months).
  
  
  RESULTS
  Clinical improvement was immediate in all patients. No complications were recorded. Recurrence of the syndrome, with restenosis of the sphincterotomy opening, was observed in six patients (19%) and was treated successfully and safely with a new papillotomy. Sump syndrome recurrence occurred 31-72 months (median: 58.5 months) after the initial treatment.
  
  
  CONCLUSIONS
  We report a considerably high recurrence rate of sump syndrome after initially successful endoscopic management and its effective endoscopic treatment with a new papillotomy. We still believe that the primary therapeutic approach in patients with sump syndrome should be endoscopic.
