Wire-assisted minor papilla precut papillotomy

Academic Article

Abstract

  • Background: Deep cannulation of the dorsal duct in patients with pancreas divisum may not be possible, even for the experienced endoscopist. This is a description of a technique to facilitate access to the dorsal duct. Methods: Patients undergoing dorsal ductography in whom endoscopic therapy was indicated and in whom a 4.5F tapered-tip catheter could not be passed into the dorsal duct over a guidewire were prospectively identified. After ductal opacification, either a 0.035- or 0.021-inch guidewire was passed into the dorsal duct; a needle-knife was then passed to the minor papilla alongside the guidewire, and with appropriate orientation, a precut papillotomy was made. Results: Eleven patients undergoing dorsal ductography for recurrent pancreatitis (10 patients) or ductal leak (1 patient) were prospectively treated with the above technique. Secretin was used in 1 patient. In all patients, after precut papillotomy the diagnostic catheter was passed without difficulty into the dorsal duct allowing for guidewire exchange and/or stent placement. Extension of the papillotomy could then be performed with the needle-knife over a pancreatic stent. Complications included pancreatitis in 1 patient. Conclusions: This technique, which uses widely available accessories, facilitates access to the dorsal pancreatic duct for endoscopic therapy.
