Summary
Surgical intervention for internal biliodigestive fistulas, often caused by gallstones, effectively treats patients. While complications occur, the chosen surgical approach leads to a high recovery rate for these complex biliary tract conditions.
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Surgical Management of Biliary Tract Diseases
- Gastrointestinal Fistula Treatment
Background:
- Internal biliodigestive fistulas are serious complications, frequently arising from cholelithiasis (gallstones) obstructing bile ducts.
- Associated conditions include purulent cholangitis, liver abscesses, pancreatitis, hepatitis, and gallstone ileus, complicating surgical decision-making.
- This study analyzes surgical treatment outcomes for 53 patients with internal biliodigestive fistulas.
Observation:
- The primary surgical strategy involves cholecystectomy, bile duct stone removal, bile drainage restoration, fistula obliteration, and hollow organ defect closure.
- For gallstone ileus, concurrent intestinal obstruction correction is also recommended.
- The overall complication rate was 35.8%, including hepatorenal insufficiency, choledochal suture incompetence, external biliary fistula, hepatic abscess, pancreatitis, and wound infection.
Findings:
- The selected surgical approach demonstrated a high success rate in treating internal biliodigestive fistulas.
- Of the 53 surgically treated patients, 49 (92.5%) achieved recovery.
- Mortality was observed in 4 patients (7.5%) due to postoperative complications.
Implications:
- The study validates a comprehensive surgical protocol for managing complex internal biliodigestive fistulas.
- Effective surgical management significantly improves patient outcomes and survival rates.
- Further research may focus on minimizing postoperative complications in this patient cohort.
