3 Clinical Trials for Various Conditions
This research project will compare the use of the double wire technique with the placement of a pancreatic duct (PD) stent to achieve deep biliary cannulation without the use of a precut papillotomy. Currently, the data supporting either of these approaches is limited to the referenced case series. More data on the success and complication rates of these techniques are needed. The investigators believe either of these approaches would be preferred by less experienced endoscopists to precut papillotomy. Consequently, it is important to differentiate these techniques and identify which patients may benefit from one or both.
Needle-knife fistulotomy (NKF) is traditionally used to achieve biliary access when standard cannulation (SC) techniques are unsuccessful. Based on technical factors and the design of prior studies, the literature suggests NKF should be reserved for expert advanced endoscopists. The aim of this study was to evaluate the efficacy and safety of NKF compared to SC for primary biliary access performed by advanced endoscopists with a range of experience including advanced endoscopy trainees.
The investigators aim is to compare outcomes between an angled-tip guidewire and a straight-tip guidewire in cannulation of the common bile duct during ERCP. This is a randomized, controlled, single-blinded study. The primary outcome is success of cannulation and secondary outcomes are incidence of post-ERCP pancreatitis, procedure duration, and rate of complication between the angled wire and straight wire.
