Resection of spleno-renal shunt resulting in enhanced liver volume in a patient with congenital portosystemic shunt concomitant with early gastric cancer. Review of Japanese cases.
A 73-year-old man recurring hepatic encephalopathy due to a congenital splenorenal shunt concomitant with early gastric cancer was successfully treated by surgical intervention. The portal pressures before and after the shunt resection were 13.5 and 18 cm H2O, respectively. The liver was slightly atrophic and the histological specimen showed slight fibrosis and mild infiltration of lymphocytes in the portal area. After the operation, the encephalopathy was improved and the several factors of liver function also recovered. Interestingly, the liver volume estimated by abdominal CT clearly increased 1 month after the shunt resection. The encephalopathy in congenital portosystemic shunt might result from chronic liver ischemia and atrophy. Moreover, the shunt resection may enlarge the functional liver volume by increasing the portal blood flow.
