Abstract
Background and purpose: Mid-size sphincterotomy associated with large balloon dilation is an alternative to wide sphincterotomy to remove complex lithiases. However, which of the two techniques is most effective remains unclear. Hence, we conducted this study to compare both methods prospectively.
Method: Since January 2012 until March 2014, 133 consecutive patients with complex stones were included. Group A underwent mid-size sphincterotomy associated with large balloon dilation and group B underwent wide sphincterotomy alone. Success rates were assessed for: Extraction of stones, ductal patency rate, the use of mechanical lithotripsy, dose, time and dose per radioscopy area as well as procedure-related complications.
