title: Endoscopic management of sump syndrome after choledochoduodenostomy: retrospective analysis of 30 cases.
abstract: BACKGROUND
  Side-to-side choledochoduodenostomy is a frequently performed operation. Postoperative biliary "sump syndrome" is infrequent, a complication for which endoscopic sphincterotomy is regarded as the treatment of choice.
  
  
  METHODS
  We retrospectively analyzed 30 cases of sump syndrome and describe the symptoms, the delay before the appearance of symptoms, laboratory abnormalities, the nature of the biliary obstruction, and the outcome of endoscopic sphincterotomy including its efficiency and complications.
  
  
  RESULTS
  The median clinical latency was 5 years (range 1 month to 28 years), the median delay between surgery and diagnosis was 6 years (range 1 month to 28 years). Fourteen patients had abdominal pain with fever, 5 had isolated abdominal pain, 4 had post-prandial pain, 4 had hepatic abscesses, and 3 had acute pancreatitis. Liver function tests were abnormal in 79%. During endoscopic retrograde cholangiopancreatography, food debris was identified in 18 patients in the biliary sump, biliary calculi in 10 patients, and a mixture of food and calculi in 2 patients. All patients underwent endoscopic sphincterotomy without complication. Recurrence during a median follow-up of 36 months (range 3 months to 11 years) was not observed.
  
  
  CONCLUSIONS
  Sump syndrome most often becomes symptomatic only after a long delay. Abdominal pain with fever was the most frequent symptom. Liver function tests were abnormal in the majority of patients. Food debris was the most frequent cause. Endoscopic sphincterotomy appeared to be a safe, reliable treatment.
