Preventing distal stent deflection using a sheath-assisted technique for malignant hilar biliary obstruction

Key Points

• The intervention notably reduces distal stent deflection, enhancing stenting efficacy.
• In a cohort with malignant hilar biliary obstruction, the sheath-assisted technique appears to lower complications.
• Assessment through observational analysis indicates improved biliary drainage outcomes.
• These findings highlight the need for advanced techniques to optimize biliary interventions.
