NCT04970030

Brief Summary

Difficult gallstones are found in about 10-15% of endoscopic retrograde cholangiopancreaticography (ERCP) performed for choledocholithiasis. There are several options for the treatment of difficult biliary lithiasis including mechanical lithotripsy and peroral cholangioscopy with electrohydraulic lithotripsy. The primary purpose of this study is to compare the effectiveness of treating difficult biliary lithiasis with ML and with EHL. The effectiveness is defined by the complete cleanliness of the biliary tract in a single endoscopic session

Outcome Measures

Primary Outcomes (1)

  • ML - EHL comparison

    The primary purpose of this study is to compare the effectiveness of treating difficult biliary lithiasis with ML and with EHL. The effectiveness is defined by the complete cleanliness of the biliary tract in a single endoscopic session

    1 day

Secondary Outcomes (2)

  • effective clearance of the biliary tract

    30 days

  • Comparison of the safety of the treatments under study

    30 days

Study Arms (2)

mechanical intracanal (ML) lithotripsy

ACTIVE COMPARATOR

TTS mechanical lithotripter

Procedure: ML lithotripsy

electrohydraulic intracolangioscopic (EHL) lithotripsy

EXPERIMENTAL

electrohydraulic lithotripsy with Autolith probe

Procedure: EHL lithotripsy

Interventions

we will proceed under fluoroscopic vision with TTS mechanical lithotripter (Trapezoid, RX Wireguided Retrieval Basket, Boston Scientific) with mechanical fragmentation of the stone and subsequent complete cleaning of the biliary tract using the fluoroscopic technique.

mechanical intracanal (ML) lithotripsy

after administration of IV antibiotic therapy, we will proceed to cholangioscopy with SpyGlass ™ DS (Boston Scientific Corporation, USA), treatment of difficult biliary lithiasis with electrohydraulic lithotripsy with Autolith probe (Northgate Technologies Inc USA) and subsequent complete cleaning of the biliary tract using the fluoroscopic technique

electrohydraulic intracolangioscopic (EHL) lithotripsy
