Biliary obstruction after gallbladder removal may be malignant, not benign. Middle-aged patients with high strictures and jaundice after an uncomplicated surgery require suspicion for missed biliary cancer.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Diagnostic Imaging

Background:

  • Post-cholecystectomy biliary strictures (BBS) are typically benign.
  • Malignant biliary obstruction mimicking benign strictures is rare and poses diagnostic challenges.

Purpose of the Study:

  • To identify characteristics of post-cholecystectomy biliary obstruction that suggest underlying malignancy.

Main Methods:

  • Retrospective analysis of 11 patients with biliary malignancy among 349 post-cholecystectomy BBS cases.
  • Comparison of demographic, clinical, and radiological features between malignant and benign strictures.

Main Results:

  • Malignant strictures occurred in older patients (mean age 52 vs 38 years) with higher rates of jaundice and pruritus.

  • Patients with malignancy had uneventful post-cholecystectomy courses, longer intervals to presentation, and more frequent high-grade hilar strictures (Bismuth type III/IV).

    • Conclusions:

    • Post-cholecystectomy biliary obstruction is not exclusively benign.
    • High bilirubin, hilar strictures, and an uncomplicated surgical history in middle-aged patients warrant suspicion for occult biliary malignancy.
