Endoscopic ultrasonography-guided B3 branch drainage/anastomosis as hepaticoduodenostomy in atrophic left hepatic lobe case

Key Points

• Effective method of hepaticoduodenostomy was demonstrated for atrophic left hepatic lobe cases.
• Endoscopic ultrasonography guided the B3 branch drainage in complex liver anatomy, enhancing outcomes.
• The procedure improves biliary drainage while minimizing invasiveness, allowing for safer interventions.
• Further validation of this technique is necessary to establish long-term effects and broader applicability.
