Summary
Percutaneous balloon dilatation (PBD) offers a safe and effective treatment for benign biliary strictures, demonstrating high success rates and lower morbidity compared to surgery. This minimally invasive approach can be repeated for recurrences without compromising future surgical options.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Hepatology
Background:
- Benign biliary strictures pose significant clinical challenges.
- Surgical interventions carry substantial morbidity and mortality risks.
- Percutaneous balloon dilatation (PBD) is an alternative therapeutic option.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of PBD for benign biliary strictures.
- To compare PBD outcomes with existing radiological and surgical series.
- To assess PBD's impact on subsequent treatment options.
Main Methods:
- Long-term follow-up of 40/101 patients with benign biliary strictures treated with PBD.
- Inclusion criteria: minimum 18-month follow-up.
- Regular clinical, biochemical (AST, ALT, gammaGT, alkaline phosphatase), and ultrasound monitoring.
Main Results:
- Mean follow-up of 33.5 months.
- Success rates varied by stricture type: 75% (bilioenteric anastomosis), 86% (iatrogenic common bile duct), 65% (sclerosing cholangitis), 80% (papillary).
- PBD exhibited lower morbidity and no 30-day mortality compared to surgery.
Conclusions:
- PBD is a safe and effective treatment for various benign biliary strictures.
- PBD offers a lower morbidity profile than surgical interventions.
- Repeated PBD is feasible for recurrences and does not preclude future surgery.
