Endoscopic ultrasound-guided choledochoduodenostomy

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Oncology

Background:

• Standard endoscopic biliary drainage (EBD) can fail in malignant biliary obstruction due to tumor infiltration or cannulation difficulties.
• Percutaneous transhepatic biliary drainage is an alternative but carries significant risks, including bleeding and bile leakage.

Purpose of the Study:

• To describe a novel technique for endoscopic ultrasonography (EUS)-guided biliary stent placement.
• To evaluate the efficacy of direct transduodenal stent insertion for malignant lower extrahepatic bile duct obstruction when EBD fails.

Main Methods:

• The study describes a direct stent insertion technique from the duodenal bulb under EUS guidance.
• This method is applied in patients with jaundice caused by malignant obstruction of the lower extrahepatic bile duct.

Main Results:

• EUS-guided biliary drainage via a direct transduodenal approach is technically feasible.
• This technique provides an effective management option for malignant biliary obstruction when conventional EBD is unsuccessful.

Conclusions:

• Direct transduodenal EUS-guided biliary drainage is a valuable alternative to percutaneous drainage.
• This approach is recommended for patients with jaundice due to inoperable malignant lower extrahepatic bile duct obstruction when EBD fails.
