Summary

Stent-guided needle knife sphincterotomy is a safe and effective endoscopic technique. This method minimizes complications in patients with challenging anatomy, including Billroth II gastrectomy or periampullary diverticula.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Sphincterotomy in patients with Billroth II gastrectomy or periampullary diverticula carries increased risks.
  • Anatomical challenges like pancreas divisum or recurrent pancreatitis complicate standard sphincterotomy procedures.

Purpose of the Study:

  • To evaluate the efficacy and safety of stent-guided needle knife sphincterotomy.
  • To assess complication rates in patients with difficult anatomy undergoing sphincterotomy.

Main Methods:

  • A retrospective review of 229 patients undergoing stent-guided needle knife sphincterotomy from 1983-1992.
  • Stent placement in the biliary or pancreatic duct to guide the sphincterotomy incision.
  • Use of electrocautery via a needle knife sphincterotome for precise incision.

Main Results:

  • Overall complication rate was 8.3% (19/229), with 17 mild and 2 moderate pancreatitis cases.
  • One patient required surgery for severe hemorrhage; no mortality or perforations were reported.
  • Successful application in diverse patient groups including Billroth II gastrectomy, periampullary diverticula, pancreas divisum, and recurrent pancreatitis.

Conclusions:

  • Stent-guided needle knife sphincterotomy is an effective and safe endoscopic approach.
  • This technique offers a low complication rate, even in patients with complex anatomical variations.
  • Precise ductal guidance ensures accurate incisions during pancreatic sphincterotomy.
