[Retrograde cholangiopancreatography (ERCP) and endoscopic sphincteropapillotomy (ES) in the diagnosis and treatment of common bile duct (CBD) lithiasis]. / Colangiopancreatografia retrograda (ERCP) si sfincteropapilotomia endoscopica (ES) in diagnosticul si tratamentul litiazei caii biliare principale (CBP).

The common bile duct (CBD) stones often gives real difficulties of diagnosis and treatment. The ultrasound (US) does not offer in a significant percentage of cases certain diagnostic data, and the unconventional imaging techniques such as computer tomography (CT) are yet less accessible. ERCP appeared in the last period as an optional method for the diagnosis of common bile duct stones, and, moreover, permitted the development of the nonsurgical treatment possibilities. ES and the extraction of stones revealed in this frame as preferable, especially in the high surgical risk cases. This study presents the results of ERCP performed in 547 and the therapeutic value of ES in 284 cases with CBD stones (conclusions of the ERCP and ES used in the clinical practice, in our clinic, in the last three years). In 81.69% cases ES managed the dezobstruction of the CBD, with a frequency of complications of 4.33% and a related mortality rate of 0.78%.
