Summary

Suprapapillary fistulosphincterotomy (FS) improves biliary cannulation success during ERCP. While effective, FS carries a higher complication risk and should be reserved for complex cases.

Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Biliary Interventions

Background:

  • The utility and safety of needle knife use in ERCP are debated.
  • Suprapapillary fistulosphincterotomy (FS) is an endoscopic technique for biliary access.

Purpose of the Study:

  • To prospectively evaluate the value and safety of FS in managing biliary disease via ERCP.
  • To determine the impact of FS on diagnostic and therapeutic success rates.

Main Methods:

  • FS was performed after failed standard cannulation attempts or when sphincterotomy was indicated.
  • The technique involves creating an opening into the common bile duct proximal to the papilla.
  • This opening was then cannulated to facilitate stone clearance or stent insertion.

Main Results:

  • FS was used in 83 of 531 patients (16%), achieving biliary cannulation in 89%.
  • FS significantly improved diagnostic success (97% vs 85%), stone clearance (96% vs 83%), and stent insertion (88% vs 64%).
  • Complications occurred in 6% of FS patients versus 1% of non-FS patients; no fatalities were reported.

Conclusions:

  • FS is a valuable adjunct for biliary disease management during ERCP.
  • Due to an increased risk of complications, FS should be reserved for high-suspicion biliary disease cases requiring further endoscopic treatment.
