ARTICLE HIGHLIGHTS
Research background
Painful chronic calcifying pancreatitis management involves pancreatic enzyme replacement therapy, extracorporeal shock wave lithotripsy (ESWL) with or without endoscopic retrograde cholangiopancreatography (ERCP), ERCP with pancreatic sphincterotomy and either balloon or basket retrieval with stent placement, peroral pancreatoscopy (POP) and/or surgery. POP utilizes two different methods for pancreatic stone lithotripsy, which are electrohydraulic lithotripsy (EHL) or laser lithotripsy (LL).
Research motivation
There are limited data regarding the safety and efficacy of POP for symptomatic pancreatic calculi.
Research objectives
We aimed to assess the safety and efficacy of both POP techniques in regard to stone fragmentation. Primary outcomes assessed involved technical and clinical success of POP. Secondary outcomes included technical and clinical success for EHL and LL, and adverse events (AE) for POP, EHL and LL.
Research methods
We conducted a comprehensive search of multiple electronic databases and conference proceedings including PubMed, EMBASE, Cochrane, Google Scholar and Web of Science databases. Statistical analysis was conducted via comprehensive meta-analysis software.
Research results
POP-guided lithotripsy was successful in patients who had failed in the first-line therapy. On indirect comparative analysis, LL was found to have higher technical and clinical success than EHL. POP AE was comparable to ESWL. The AE for EHL and LL was similar on indirect comparison. PEP was the most common AE and was comparable to ESWL.
Research conclusions
POP-guided lithotripsy is a viable option for management of patients with chronic pancreatitis and symptomatic PD stones. We found LL technique to have a higher technical and clinical success rate with comparable AE rates.
Research perspectives
Further randomized controlled trials are needed for head to head comparison of the two techniques and evaluate if POP can be a potential first line therapy in these cases.
