Transhepatic dilatation of choledochoenterostomy strictures

Area of Science:

• Interventional Radiology
• Hepatobiliary Surgery
• Gastroenterology

Background:

• Postsurgical strictures can cause obstructive jaundice, a serious condition.
• Percutaneous transhepatic biliary drainage (THD) is an option for managing biliary obstruction.

Observation:

• THD was used in 13 patients with postsurgical stricture-induced obstructive jaundice over seven years.
• Nine patients underwent internal drainage with dilatation; four had external drainage alone.

Findings:

• Eight of nine patients with internal drainage and dilatation achieved asymptomatic status with normal bilirubin.
• External drainage alone had varied results, with some patients requiring further surgery or experiencing incomplete relief.
• One patient died from sclerosing cholangitis, and another with biliary cirrhosis had only moderate improvement.

Implications:

• Internal drainage with dilatation appears to be a successful approach for managing postsurgical biliary strictures.
• Careful patient selection and management are crucial for optimizing outcomes in THD procedures.
• THD offers a less invasive option for relieving obstructive jaundice compared to open surgery.
