Needle-knife sphincterotomy (NKS) is effective for difficult biliary access, with an 87.5% success rate. Using a pancreatic prosthesis improved outcomes and reduced complications in this endoscopic retrograde cholangiopancreatography procedure.

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Biliary Interventions

Background:

  • Needle-knife sphincterotomy (NKS) is a technique for achieving biliary access when standard methods fail.
  • Difficult cannulation of the common bile duct presents a challenge in endoscopic retrograde cholangiopancreatography (ERCP).

Purpose of the Study:

  • To evaluate the efficacy and safety of NKS in patients with difficult biliary cannulation.
  • To identify factors influencing the success rate and complication incidence of NKS.

Main Methods:

  • A prospective study of 72 patients undergoing NKS for difficult common bile duct cannulation.
  • Analysis of success rates, number of sessions, association with underlying disease, and complication rates.

Main Results:

Related Experiment Videos

  • NKS achieved successful biliary access in 87.5% of patients, with 73% successful on the first attempt.
  • Biliopancreatic neoplasms were associated with a lower success rate (72.7%) compared to other diagnoses (94%).
  • Complications occurred in 16.6% of cases; use of a pancreatic prosthesis correlated with higher success and fewer complications.

Conclusions:

  • NKS is a safe and effective procedure for difficult biliary cannulation.
  • Biliopancreatic neoplasms are a risk factor for NKS failure.
  • The complication rate is comparable to existing literature, with no severe pancreatitis or perforations observed.
