BACKGROUND: In cirrhotic patients with portal hypertension prophylactic portasystemic shunts have been found to be ineffective as deaths from post-shunt liver failure exceed those from bleeding. However, in patients with non-cirrhotic portal hypertension, variceal bleeding rather than liver failure is the common cause of death. In developing countries shortage of tertiary health-care facilities and blood banks further increases mortality due to variceal bleed.
AIM: To study the results of prophylactic operations to prevent variceal bleeding in patients with portal hypertension due to non-cirrhotic portal fibrosis (NCPF).
METHODS: Between 1976 and 2001, we performed 45 prophylactic operations in patients with NCPF, if the patients had high-risk esophagogastric varices or symptomatic splenomegaly and hypersplenism. Proximal lienorenal shunt was done in 41 patients and the remaining underwent splenectomy with (2 patients) or without (2 patients) devascularization.
RESULTS: There was no operative mortality. Thirty-eight patients were followed up for a mean 49 (range, 12-236) months. Three patients bled - one was variceal and two due to duodenal ulcers; none died of bleeding. There were 2 late deaths (6 weeks and 10 years after surgery), one from an unknown cause and one due to chronic renal failure. The delayed morbidity was 47%. This included 7 patients who developed portasystemic encephalopathy, 4 glomerulonephritis, 2 pulmonary arteriovenous fistulae and 5 ascites requiring treatment with diuretics. Thus only 20 (53%) patients were symptom-free on follow up.
CONCLUSIONS: Prophylactic surgery is safe and effective in preventing variceal bleeding in NCPF but at the cost of high delayed morbidity.
