Balloon dilatation of benign biliary strictures
Radiology
|June 1, 1984
Summary
Percutaneous transhepatic balloon dilatation shows limited success for benign postoperative biliary strictures. Repeated, high-pressure dilatations with large indwelling stents may improve outcomes for this surgical complication.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Biliary Surgery
Background:
- Benign postoperative biliary strictures are a challenging surgical complication.
- Current management strategies often have limited success rates.
Observation:
- Six patients with benign postoperative biliary strictures underwent percutaneous transhepatic balloon dilatation.
- The procedure was curative in only one patient.
Findings:
- Percutaneous transhepatic balloon dilatation alone demonstrated a low curative rate.
- Repeated, long-term, high-pressure dilatations are indicated for effective treatment.
- Utilizing an inflation device and pressure gauge ensures optimal dilatation parameters.
- Large caliber catheters should be retained as indwelling stents post-procedure.
Implications:
- Early consideration of non-surgical management, such as percutaneous dilatation, may improve the salvage rate of biliary strictures.
- This approach could potentially reduce the need for re-operation and associated morbidity.
- Further research is warranted to optimize percutaneous techniques for biliary stricture management.
