Methods: This nationwide retrospective cohort research was conducted in 2 parts using information from a national administrative database (PMSI). The 90-day morbidity of MBS with or without CC was first compared in a matched trial (propensity score). Second, we observed medium-term biliary complication following MBS when no CC had been performed during MBS up to 9 years after MBS (minimum 18 months).
