BACKGROUND Although stenting for the treatment of large and multiple common bile duct stones has been acceptable to everyone, its efficacy and outcome have not been studied in comparison with other endoscopic procedures. The purpose of this study was to compare the consequences of stenting and endoscopic papilla balloon dilatation for the treatment of large and multiple common bile duct stones. METHODS In a double-blind clinical trial, of 431 patients with bile duct stones referred to the treatment center, 64 patients with multiple common bile duct stones ( ≥ 3) and more than 15 cm were selected for the study, then by random allocation rule the participants were allocated in two groups. They were entered into two different endoscopic papillary balloon dilatation (EPBD) and common bile ducts stenting treatments so that both procedures were performed by a person. Both groups were assessed from the point of views therapeutic outcomes such as duct cleaning, pancreatitis, isolated pain, and duct rupture. Data were collected by a self-made questionnaire that was used before and after the procedure to obtain the needed information. Then data were analyzed using SPSS software version 22 and descriptive and analytical tests were used as appropriated.
