Use of Methylene Blue Dye During Laparoscopic Cholecystectomy for Mapping of Extrahepatic Biliary Tree

Key Points

• The aim is to evaluate the effectiveness of methylene blue dye in mapping the extrahepatic biliary tree during laparoscopic cholecystectomy.
• Conducted a randomized trial involving patients undergoing laparoscopic cholecystectomy.
• Utilized methylene blue dye for surgical mapping of the extrahepatic biliary tree.
• Analyzed outcomes related to biliary identification and complications.
• Methylene blue dye significantly improved identification rates of the biliary anatomy compared to standard techniques.
• Reduction in intraoperative complications was observed in the experimental group using methylene blue.
• Event rates and statistical significance were established, supporting dye’s clinical utility.
