ENgLISH SUMMArY
introduction: Symptoms of choledocholithiasis can appear after
cholecystectomy. Stones diagnosed during the first two years following
surgery are assumed to have been present at the time of surgery.
The purpose of this study was to study patients who presented with
choledocholithiasis at Landspitali - The National University Hospital of
Iceland, during the period 2008-2011, who had previously undergone
cholecystecomy and to assess whether cholodocholithiasis is underdi-
agnosed at the time of cholecystectomy.
Material and methods: The study was retrospective, data was collec-
ted from medical records at Landspitali. Among recorded data were liver
function tests, imaging results, time from surgery to diagnosis, treatment
and complications.
Results: Forty patients presented with choledocholithiasis after
previous cholecystectomy. Mean age was 50 years (20-89) and women
were 24 (60%). Mean time from surgery to diagnosis was 382 days.
Diagnosis was confirmed with imaging in 35 (87.5% cases). Thirty
six (90%) patients were treated with ERCP, one with PTC and one
underwent open surgery. Three patients healed without treatment. Three
patients developed complications from treatment. Thirty one (77.5%)
had choledocholithiasis in the first 2 years following surgery. Incidence
of previous choledocholithiasis, elevated bilirubin or widening of the
choledochus without visible stones where similar for those diagnosed
with choledocholithiasis in the first two years and those diagnosed later.
Conclusion: Majority of patients are treated without surgery. Most sto-
nes are diagnosed during the first two years following surgery. For the
majority of cases it can not be concluded that stones should have been
suspected at time of cholecystectomy.
