Abstract:
Objective:To investigate the efficacy and safety of a new China-made direct visualization system of peroral cholangiopancreatography in the diagnosis and treatment of biliopancreatic diseases.Methods:Clinical data of 37 patients who underwent endoscopic examination through the direct visualization system of peroral cholangiopancreatography at Digestive Endoscopy Center of Nanjing Drum Tower Hospital from April 2020 to June 2021 were retrospectively analyzed. Technical success rate and complications were analyzed.Results:The examination was completed in 37 patients through the system. The technical success rate was 100.0%. The nature of biliary stricture was confirmed in 24 cases, presenece or absence of bleeding or residual stones in the bile duct was confirmed in 6 cases, neoplasm or residual stones in the pancreatic duct was determined in 2 cases, biliary stricture was passed assisted with visualized guidewire in 2 cases, and lithotripsy was performed assisted with biliary laser in 3 cases. Nine patients were pathologically diagnosed as having malignant biliary stricture, and 8 of them were confirmed malignant by the system. Drainage was performed in 34 cases after the examination. There were 3 cases of cholangitis, 4 cases of bacteremia and 2 cases of postoperative pancreatitis after the operation, which were relieved in a short time after conservative treatment. Bleeding occurred in 1 case which was improved after two times of endoscopic hemostasis.Conclusion:The new direct visualization system of peroral cholangiopancreatography is safe and effective in the diagnosis and treatment of biliopancreatic diseases.
