OBJECTIVE: To evaluate the entire spectrum of endoscopic retrograde cholangiopancreatography procedure including site of stent migration, techniques of stent retrieval, success and complications. METHODS: The retrospective study was conducted at Dr Ruth Pfau Civil Hospital Karachi, and comprised data from January 2010 to January 2017of patients who underwent endoscopic retrograde cholangiopancreatography for the retrieval of stent migrated in the common bile duct, pancreatic duct or pancreatic pseudocyst or were found to have migrated stent during either stent removal or exchange and where attempts were made to remove the stent. A team of expert endoscopists had performed all the procedures. SPSS 17 was used for statistical analysis. RESULTS: There were 5700 procedures performed on 4800 patients. Pancreato-biliary stenting was done in 1229(21.56%) patients; 745(60.61%) with benign conditions and 484(39.38%) with malignant. Stent migration was found in 51(4.14%) patients; 30(58.8%) males and 21(41.2%) females. In terms of clinical presentation, right upper quadrant pain was the most common 9(17.6%). Technical success was achieved in all (100%) cases, with firstprocedure success in 45(88.2%). There was no complication or procedure-related mortality. CONCLUSIONS: In patients with stent migration, endoscopic retrograde cholangiopancreatography was found to be a safe and effective modality for stent retrieval.
