Nonanastomotic biliary strictures (NABS) after liver transplantation (LT) are uncommon but significantly reduce graft survival. Hepatic artery thrombosis and donation after cardiac death donors predict NABS development.
Area of Science:
- Hepatology
- Transplant Surgery
- Gastroenterology
Background:
- Biliary strictures are a significant complication after liver transplantation (LT), impacting patient morbidity and mortality.
- Limited research exists on the specific effects of nonanastomotic biliary strictures (NABS) on graft outcomes post-LT.
Purpose of the Study:
- To investigate the incidence and predictors of nonanastomotic biliary strictures (NABS) following liver transplantation (LT).
- To evaluate the impact of NABS on long-term graft survival after LT.
Main Methods:
- Retrospective analysis of 649 liver transplant recipients.
- Multivariate analysis to identify independent predictors of NABS, including hepatic artery thrombosis (HAT) and donation after cardiac death (DCD) donors.
Main Results:
- The incidence of NABS was 2.6% (17 patients).
- Hepatic artery thrombosis (HAT) (OR: 15.75) and the use of livers from DCD donors (OR: 8.292) were significant predictors of NABS.
- Graft survival was markedly worse in patients with NABS compared to those without (5-year survival: 0% vs. 76.4%, P < .001).
Conclusions:
- While NABS incidence was low, it significantly impairs graft survival post-LT.
- Close monitoring for NABS is crucial in liver grafts experiencing HAT or sourced from DCD donors.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
