Abstract
BACKGROUND: Needle knife papillotomy (NKP) and fistulotomy (NKF) are the two most commonly used rescue techniques for patients with difficult biliary cannulation (DBC). Anatomy of the major duodenal papillae (MDP) influences the optimal precut technique for biliary access. However, comparative studies of the success and safety of NKP and NKF based on the anatomy of MDP have been scarce. METHODS: Patients with intact MDPs for therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) in our center were enrolled. Early needle knife precuts were uniformly applied to patients with DBC. Difficult MDPs were classified into one of five types based on their endoscopic anatomy. Each type of MDP was allocated to NKP or NKF treatment. Patients with types 1 and 2 papillae always received NKF, 3 and 4 received NKP, and 5 could receive either. The safety and efficacy were analyzed between NKP and NKF, and among different types of MDPs. RESULTS: A total of 188 out of 1674 patients undergoing ERCP satisfied the criteria for early precutting: 75 patients were assigned to the NKP group and 113 to the NKF group. The total initial success rate of biliary cannulation (ISRBC) of the precut techniques (both NKP and NKF) for patients with DBC was 91.5%. The ISRBC of patients of the NKP group was similar to that of the NKF group (90.7% vs 92.0%, P > 0.05). The ISRBC of the patients in the swollen MDP subgroup (96.1%) was higher than that of patients in the distorted MDP subgroup (81.8%, P = 0.030). The total and specific complications of the patients of the NKP group were similar to those of the NKF group (P > 0.05). CONCLUSIONS: NKP and NKF, as selected on the basis of MDP anatomy, are equally safe and highly efficient for patients with DBC to allow biliary cannulation. Patients with swollen MDPs had a higher ISRBC than patients with distorted MDPs. Selecting a precut method based on MDP anatomy is an effective and safe strategy for patients with DBC.
