Surgical repair of benign postoperative biliary strictures offers higher success rates than balloon dilatation. Surgery is recommended, but dilatation remains an option for high-risk patients.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Hepatobiliary Surgery

Background:

  • Benign postoperative biliary strictures can complicate hepatobiliary surgery.
  • Management options include surgical repair and endoscopic or percutaneous interventions.

Purpose of the Study:

  • To compare the efficacy and outcomes of surgical repair versus balloon dilatation for benign postoperative biliary strictures.
  • To evaluate complications, success rates, and long-term results of both treatment modalities.

Main Methods:

  • Retrospective review of 42 patients undergoing 45 procedures for benign postoperative biliary strictures between 1979 and 1987.
  • Comparison of outcomes between patients treated with surgical repair (Roux-Y hepaticojejunostomy) and balloon dilatation.
  • Analysis of success rates, complications (including hemobilia), follow-up duration, hospital stay, and cost.

Main Results:

  • Surgical repair achieved an 88% success rate, significantly higher than the 55% success rate for balloon dilatation (p < 0.02).
  • Significant hemobilia was more frequent after balloon dilatation (20%) compared to surgery (4%) (p < 0.02).
  • No significant differences were observed in follow-up duration, hospital stay, or cost between the two groups.

Conclusions:

  • Surgical repair of benign postoperative biliary strictures leads to superior long-term outcomes with fewer complications requiring further therapy.
  • Balloon dilatation serves as a viable alternative for patients with high surgical risk or those unwilling to undergo further operations.
