Variceal hemorrhage in biliary atresia
Insights
Biliary atresia patients undergoing Kasai
Area of Science:
- Pediatric surgery
- Gastroenterology
- Hepatology
Background:
- Biliary atresia is a severe neonatal liver disease requiring surgical intervention.
- Kasai's operation is a common procedure to restore bile flow.
- Portal hypertension and variceal hemorrhage are known complications.
Purpose of the Study:
- To investigate the incidence and characteristics of variceal hemorrhage after Kasai's operation.
- To identify ultrasonographic findings associated with hemorrhage.
- To evaluate treatment outcomes for variceal hemorrhage.
Main Methods:
- Retrospective analysis of 47 patients with sustained bile drainage post-Kasai's operation.
- Documentation of variceal hemorrhage, its origin, and timing.
- Ultrasonographic assessment of intrahepatic venous radicles.
- Review of treatment strategies including endosclerosis, shunt disconnection, and splenic embolization.
Main Results:
- 23% of patients experienced major variceal hemorrhage.
- Hemorrhage originated from the esophagus or exteriorized conduit.
- Ultrasonography revealed decreased intrahepatic venous radicles in all examined patients.
- Primary treatments were effective in preventing recurrent hemorrhage during follow-up.
Conclusions:
- Variceal hemorrhage is a significant complication following Kasai's operation for biliary atresia.
- Ultrasonographic findings of decreased intrahepatic venous radicles may indicate portal hypertension.
- Current treatment modalities appear effective in managing and preventing recurrent hemorrhage.
Abstract:
Eleven of 47 patients (23%) with sustained bile drainage after Kasai's operation for biliary atresia had major variceal hemorrhage. Hemorrhage was esophageal in origin in five children and from the exteriorized conduit in eight. Two patients bled from both sites. The first major hemorrhage occurred at an average patient age of 40.4 months. Clinical manifestations of portal hypertension were poorly correlated with liver functions, however, markedly decreased calibre of the intrahepatic venous radicles was noted by ultrasonography in all patients examined. Primary treatment was by esophageal endosclerosis or by disconnection of portosystemic shunts coincident with stomal closure. Adjunctive splenic embolization was employed in six patients. Recurrent hemorrhage has not been encountered in limited follow-up.
