Background And Aims: Difficult biliary cannulation (DBC) is a marker for prolonged procedure time and increased adverse event rate (AER) during endoscopic retrograde cholangiopancreatography (ERCP). We previously showed that EUS-guided rendezvous procedure (EUS-RV) had a higher single session success rate than precut papillotomy (PcP) in DBC patients. The present randomized study aims at comparing the technical success and AER between the two approaches.

Perforations represent rare but serious complications in ERCP. Although several therapeutic algorithms have been proposed to properly address these potentially life-threatening events, there is still no clear consensus on their management. We conducted a single-center retrospective study in order to assess the incidence of ERCP-related perforations and their management, as well as clinical outcomes.

Background: Needle-knife precut papillotomy (NKP) is typically performed freehand. However, it remains unclear whether pancreatic stent (PS) placement can improve the outcomes of NKP.

Aim: To explore whether PS placement improves the success rate of NKP in patients with difficult biliary cannulation.

Article Synopsis
  • This study compared two alternative techniques, transpancreatic sphincterotomy (TPS) and precut sphincterotomy (PCS), for accessing the biliary tree during difficult ERCP procedures.
  • TPS showed higher successful cannulation rates (86.5%) compared to PCS (69.7%), but both were lower than the standard sphincterotomy control group (92.4%).
  • Despite higher cannulation success, TPS was associated with more adverse events (24.1%) compared to PCS (18.8%) and the control group (15.5%), with increased rates of pancreatitis and perforation in the TPS group.
