Consensus document for the transcystic approach to choledocholithiasis with ultrathin flexible choledochoscope.

The transcystic laparoscopic approach to manage choledocholithiasis using ultrathin flexible choledochoscopes is aimed at reducing complications linked to ERCP and transductal techniques when treating common bile duct stones with gallbladder in situ. Despite their advantages, transcystic techniques are not being widely adopted, highlighting the need for structured protocols, a multidisciplinary approach, and adequate resource allocation to optimize outcomes. This consensus document addresses key issues to standardize the approach, based on the responses to the 25 questions posed to the panel of experts. The recommendations issued, based on the evidence and expert opinion, cover the key factors for the success of the technique, including appropriate patient selection, technical characteristics of the approach, advanced equipment required, etc. This comprehensive guide aims to standardize the technique in order to improve patient outcomes and ensure safe, effective treatment of choledocholithiasis.
