Endoscopic sphincterotomy using an isolated-tip needle-knife papillotome after Billroth II gastrectomy

A needle-knife papillotome (NKP) has been used instead of a standard sphincterotome knife for difficult endoscopic sphincterotomy (ES) in patients with a surgically altered anatomy such as Billroth II gastrectomy. However, use of an NKP may increase the risk of postprocedure pancreatitis because its tip is more directly in contact with the pancreatic duct, causing electric damage. The newly developed isolated-tip NKP (ITNKP) (Iso-Tome, second generation, MTW Endoskopie, Wesel, Germany) is a modified NKP that has a round tip made of sapphire to prevent electrical damage.
