SpyGlass by single-operator in ERCP-guided cholangiopancreatoscopy system for bile-duct disorders

Abstract

Objective To evaluate the clinical utility of SpyGlass single-operator ERCP-guided cholangiopancreatoscopy system for the diagnosis and treatment of bile duct disorders. Methods A total of 9 patients with biliary diseases were treated with SpyGlass single-operator ERCP-guided cholangiopancreato-scopy system. Four patients with large bile duct stones accepted laser hthotripsy, and stones were removed by ERCP. Five patients with indeterminate bile duct stricture accepted cholangioscopy-guided sampling. All patients underwent ENBD, routine blood test, blood amylase test, oral food and water restriction, acid sup- pression and prophylactic antibiotics. Results SpyGlass was successful in all patients with a manipulating time of 21.2min and total procedure time of 46. 2min. Complete stone clearance was achieved in all 4 pa-tients with large biliary stones. Sample quality was adequate in all patients with bile duct stricture with 2 pa-tients diagnosed as having malignant biliary tumor and 3 as inflammatory bile duct stenosis. Post-ERCP com plications including mild pancreatitis in 2 patients, and the patients recovered gradually after corresponding treatment. Conclusion ERCP-guided cholangiopancreatoscopy with the SpyGlass system is technically fea-sible and can be successfully and safely performed in patients with biliary disorders.
