Summary
Needle-knife fistulotomy (NKF) offers superior biliary access for duodenal papillary tumors compared to conventional cannulation methods (CCMs). NKF demonstrates higher success rates and fewer complications, improving patient outcomes in ERCP procedures.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Oncology
Background:
- Duodenal papillary tumors present challenges for biliary access during ERCP.
- Conventional cannulation methods (CCMs) have limitations in efficacy and safety.
- Needle-knife fistulotomy (NKF) is an alternative technique for biliary access.
Purpose of the Study:
- To compare the efficacy and safety of NKF versus CCMs for primary biliary access.
- To evaluate cannulation success rates, procedure times, and adverse events.
- To determine the optimal cannulation method for patients with duodenal papillary tumors.
Main Methods:
- Retrospective analysis of consecutive patients undergoing ERCP for duodenal papillary tumors.
- Comparison of NKF (n=124) and CCM (n=280) groups.
- Assessment of successful cannulation rates, procedure times, and adverse event prevalence.
Main Results:
- NKF achieved significantly higher successful cannulation rates (99.2% vs. 88.9%) and shorter procedure times.
- NKF significantly reduced unintentional pancreatic duct cannulation (1.6% vs. 20%) and overall adverse events (3.2% vs. 10.7%).
- Post-ERCP pancreatitis rates were significantly lower with NKF (1.6% vs. 6.8%).
Conclusions:
- NKF is a more effective and safer technique than CCMs for primary biliary access in patients with duodenal papillary tumors.
- NKF improves procedural success and reduces complications like post-ERCP pancreatitis.
- The findings support NKF as a preferred method for this patient population.
