Ileal conduit hemorrhage secondary to portal hypertension
Insights
Massive hemorrhage from ileal conduits can occur with portal hypertension. Surgical shunts and colon conduits offer successful management for this rare complication.
Area of Science:
- Gastroenterology and Hepatology
- Urology
- Vascular Surgery
Background:
- Portal hypertension is a serious complication of liver disease.
- Ileal conduits are urinary diversions that can be susceptible to vascular issues.
- Portosystemic varices can form due to altered blood flow dynamics.
Observation:
- Three patients presented with massive ileal conduit hemorrhage, portal hypertension, and associated varices.
- One patient with advanced cirrhosis (Child-Pugh C) died despite conservative management.
- Two patients underwent splenorenal shunts followed by creation of colon conduits, achieving positive outcomes.
Findings:
- The triad of ileal conduit hemorrhage, portal hypertension, and varices is a rare but significant clinical entity.
- Surgical intervention involving shunts and alternative conduit creation can effectively manage this condition.
- Angiography is crucial for diagnosing these complex vascular abnormalities.
Implications:
- Understanding the pathophysiology of portosystemic varices in ileal conduits is vital for timely diagnosis and treatment.
- This case series highlights the potential for successful surgical management in select patients.
- Further research into the mechanisms of varix formation in urinary diversions is warranted.
Abstract:
The clinical features and management of 3 patients who presented with the triad of massive hemorrhage from the ileal conduit, portal hypertension due to liver disease, and portosystemic varices related to the conduits are described. One patient, a class C cirrhotic, was treated conservatively and died of blood loss and hepatic coma. Two patients were managed with splenorenal shunts initially, followed by creation of colon conduits, and are currently doing well. Surgical approximation of areas draining in the portal and systemic circulation with subsequent development or adhesion-related varices probably explains the predilection for involvement of the ileal conduit and may explain the presence of varices in mild to moderate portal hypertension before other signs of hepatic decompensation are evident. Superior mesenteric angiography with special attention directed at the venous phase is necessary to document this entity.
