    Spontaneous internal biliary fistulas, often caused by gallstones (cholelithiasis), present diagnostic and surgical challenges. Early gallbladder removal (cholecystectomy) is recommended to improve outcomes.

    Area of Science:

    • Gastroenterology
    • Surgical Gastroenterology
    • Hepatobiliary Surgery

    Background:

    • Spontaneous internal biliary fistulas are rare but serious complications.
    • Cholelithiasis and peptic ulcer disease are the primary etiologies.
    • Diagnosis and surgical management can be complex.

    Purpose of the Study:

    • To report the etiology, diagnostic methods, and surgical outcomes for patients with spontaneous internal biliary fistulas.
    • To evaluate the effectiveness of various surgical interventions.
    • To emphasize the importance of early cholecystectomy.

    Main Methods:

    • Retrospective review of 58 patients with spontaneous internal biliary fistulas.
    • Analysis of etiological factors, diagnostic investigations, and surgical procedures.

    Related Experiment Videos

  • Assessment of preoperative diagnosis rates and incidental findings at surgery.
  • Main Results:

    • Cholelithiasis (53 patients) and peptic ulcer (5 patients) were the main causes.
    • Preoperative diagnosis was achieved in 31 patients; 27 were diagnosed intraoperatively.
    • Overall mortality was 5%, and morbidity was 13%.

    Conclusions:

    • Surgical treatment for internal biliary fistulas yielded unsatisfactory results.
    • Early cholecystectomy in patients with cholelithiasis is strongly advocated to prevent such complications.
