Abstract

OBJECTIVES: Per oral pancreatoscopy (POP) with electrohydraulic lithotripsy (EHL) or laser lithotripsy (LL) permits stone fragmentation and removal during endoscopic retrograde cholangiopancreatography. Our study evaluates the safety and efficacy of POP in patients with main pancreatic duct (PD) stones. METHODS: This was a cohort study of patients undergoing POP with EHL/LL for PD stones between January 2000 and March 2011. Technical success was defined as complete or partial stone clearance, and clinical success as greater than 50% reduction in opiate use, pain, or hospitalizations. RESULTS: Forty-six patients underwent POP for PD stones using a 10F cholangioscope (POP-Endo) (n = 31) or catheter-based system (POP-Cath, n = 15). Electrohydraulic lithotripsy/LL was performed in 39 (85%) of 46 patients. Stone extraction without EHL or LL was performed in 7 (15%) of 46 patients. Technical success for POP-Endo versus POP-Cath was 27 (87%) of 31 versus 15 (100%) of 15 patients (P = 0.29). Complete clearance was achieved in 21 (68%) of 31 versus 11 (73%) of 15 patients, respectively (P = 0.519). Per oral pancreatoscopy-related complications were found in 10%. Follow-up in 43 (93%) of 46 patients was a median of 18 months (range, 1-60 months). Overall clinical success was 74%. CONCLUSIONS: Per oral pancreatoscopy-guided endotherapy leads to partial or complete stone clearance in most patients with PD stones. The technical success rates between POP-Endo versus POP-Cath systems appear similar and are associated with clinical improvement in most patients.
