ObjectivesPainful chronic pancreatitis (CP) is often associated with main duct obstruction due to stones.Approaches to management are challenging, including surgery, extracorporeal shock wave lithotripsy, or endoscopic approaches. Here we report our experience of pancreatoscopy + electrohydraulic lithotripsy (EHL) for pancreatic duct (PD) stones using SpyGlass.
MethodsWe retrospectively audited the use of SpyGlass (Legacy & DS™) + EHL. Indication, procedural details, and clinical outcome were assessed.
Results118 SpyGlass + EHL procedures for stones were performed, of which 8 (7%) for pancreatic stones, in 6 patients (3 female, mean age 45 years ±7 years). All patients had painful CP, with radiological evidence of a dilated PD, and main duct stone disease. Surgical options had been considered in all cases. Stone fragmentation and PD decompression was achieved in 83% (n=5) without complications. Two patients required two EHL procedures to achieve clearance. One patient failed clearance, pancreatoscopy revealed a stone in the adjacent parenchyme and not in PD. All patients with successful EHL had pain relief/marked improvement at clinical review (mean follow-up 2.7 ±1.1 years).
ConclusionPancreatoscopy + EHL may have a valuable role in treating obstructing pancreatic ductal stones, possibly avoiding the need for surgery in some patients.
