Introduction: Duodenal diverticula are pouches of the mucosa, submucosa, and scattered muscle cells that extend through the intestinal wall. In this study, we aimed to classify the papilla position according to presence of PAD and evaluate the impact of papilla position on the success rate and post ERCP complication in the patients with PAD.
Methods: This cross-sectional study was performed on 1260 patients with bile duct problems underwent ERCP. Patients with diverticulum were considered as the first group and the patients without diverticulum as the second group. In this study, SPSS Version 18 software, Chi-square and Students T-test were used, respectively.
Results: 239 patients had peripheral diverticula. The mean age of participants was 68.9±10.3. In 239 patients with diverticulum Type 1=48.2%, Type 2 =37.6%, Type 3 =5.1%, Type 4 =9.1% the success rate in Type 1 was 97% (p-value: 0.003). In the patients with type 3, the cannulation was difficult and had a low success rate, with more complications.
Conclusion: Classification of PAD can predict success rate in the patients with PDA, and can predict post ERCP complication rates.
