Hepaticojejunostomy Surgical Principles

Preoperative Considerations

The fundamental principle of hepaticojejunostomy is creating a tension-free, mucosa-to-mucosa biliary-enteric anastomosis using healthy, non-ischemic, non-inflamed, and non-scarred bile duct tissue, as recommended by the American College of Surgeons 1

Remove all scar tissue and devitalized tissue from the proximal bile duct stump before anastomosis, as anastomosis performed on ischemic or scarred tissue is the primary cause of postoperative anastomotic leakage and stricture formation, according to the American College of Surgeons 1
Identify and expose healthy bile duct mucosa with adequate caliber, ensuring the proximal bile duct has normal mucosal characteristics before proceeding, as suggested by the European Association for the Study of the Liver 2

Use fine suture technique with 5-0 or 6-0 sutures, selecting size according to bile duct wall thickness, with either absorbable or non-absorbable materials acceptable, as recommended by the American College of Surgeons 2
Ensure good mucosal apposition between bile duct and jejunal mucosa, as this is essential for long-term patency, according to the World Journal of Emergency Surgery 3, 4

Preserve blood supply to the bile duct during dissection, as vascularized ducts are the mainstay of successful reconstruction, as suggested by the World Journal of Emergency Surgery 3, 4
Associated vascular injury (particularly hepatic artery injury) is associated with worse outcomes, including higher rates of anastomotic strictures and biliary cirrhosis, according to the World Journal of Emergency Surgery 3

Create a Roux-en-Y jejunal limb of adequate length (typically 40-60 cm) to prevent reflux of enteric contents into the biliary tree, as recommended by the American Journal of Transplantation 6

For injuries detected intraoperatively or within 72 hours, early repair by an experienced HPB surgeon can be performed, as suggested by the World Journal of Emergency Surgery 7, 5
Referral to a tertiary HPB center is essential if local HPB expertise is unavailable, as primary repair attempts by non-expert surgeons have higher failure rates, morbidity, and mortality, according to the World Journal of Emergency Surgery 4, 5

Anastomotic stricture rates range from 4.1% to 69%, with most studies reporting 10-20%, occurring at a median time of 11-30 months postoperatively, as reported by the World Journal of Emergency Surgery 3

Never perform anastomosis on ischemic, inflamed, or scarred bile duct tissue, as this guarantees failure, as recommended by the American College of Surgeons 1
Avoid end-to-end bile duct anastomosis when tissue loss is present, as this is associated with increased failure rates compared to hepaticojejunostomy, according to the World Journal of Emergency Surgery 4
