Distal splenorenal shunt in children
Journal of Pediatric Surgery
|June 1, 1978
Summary
The Warren shunt decompresses esophageal varices in portal hypertension patients. While effective for some, further study is needed to confirm its long-term safety and efficacy, especially in children.
Area of Science:
- Gastroenterology
- Surgical Procedures
- Vascular Surgery
Background:
- Esophageal varices are a serious complication of portal hypertension.
- Recurrent bleeding from varices poses significant mortality risk.
- The Warren shunt aims to decompress varices while preserving portal flow.
Purpose of the Study:
- To evaluate the efficacy and safety of the distal splenorenal end-to-side anastomosis (Warren shunt).
- To assess the Warren shunt's impact on portal hypertension and liver blood inflow.
- To determine the procedure's potential in managing recurrent esophageal bleeding.
Main Methods:
- A cohort of seven patients with portal hypertension underwent the Warren shunt procedure.
- Patients had conditions including post-necrotic cirrhosis, portal thrombosis, and schistosomiasis.
- All patients presented with recurrent esophageal bleeding.
Main Results:
- Five of the seven Warren shunts remained patent post-procedure.
- Two shunts thrombosed, indicating a potential complication.
- No mortality was observed in the study cohort.
Conclusions:
- The Warren shunt can decompress esophageal varices and manage bleeding in portal hypertension.
- Patency rates suggest variability in outcomes.
- Long-term evaluation is crucial to establish the distal selective splenorenal shunt as a safe and physiologic option, particularly for pediatric patients.
