| Abstract;Pre-cutting improves the success rate of cannulation into the common bile duct. However, this technique is not prevalent in Japan because of the postoperative complications such as bleeding, perforation and acute pancreatitis. We have reported the efficacy of the new typed pre-cutting papillotome which was equipped not only with a lumen for contrast materials but also with an independent lumen for guide wires. This papillotome has an advantage that the operation of the guide wire and the injection of contrast materials can be carried out simultaneously. We made a few modifications to the previously reported pre-cutting papillotome. In the present study we estimated the modified pre-cutting papillotome that has a 20mm knife in length (half of the proximal side being Clever cut coating) and does not have a leading tip. We applied the papillotome in 5 patients with common bile duct stones and a patient with pancreatic head cancer in whom selective bile duct cannulation had failed. Selective cannulations into the bile ducts were succeeded in 5 of 6 patients on the initial attempt of pre-cutting (success rate: 83.3%) without any complications. There was no significant difference in success rate of pre-cutting between two types of the papillotomes. However, the modified papillotome made not only pre-cutting procedure easier but also EST following pre-cutting easier. Although further studies with a large number of patients are needed to evaluate the efficacy of the papillotome, this papillotome may help to increase the safety and the success rate of pre-cutting.
