Effect of coronary-caval shunt combined with partial pericardial devascularisation on oesophageal and gastric variceal bleeding caused by portal hypertension.

Abstract

To investigate the effect of coronary-caval shunt combined with partial pericardial devascularisation on oesophageal and gastric variceal bleeding caused by portal hypertension. Between January 2005 and January 2015, coronary-caval shunt operations combined with partial pericardial devascularisation were performed electively on 15 cirrhotic patients with portal hypertension. All of these patients had a history of oesophageal and gastric variceal bleeding. The clinical and follow-up data of these patients were reviewed retrospectively. Another 15 patients receiving non-surgical treatments in a similar follow-up period were used as controls to compare the preventive effects of different treatment strategies on rebleeding. All of the 15 surgical procedures were performed successfully, and no severe complications occurred. Among these, autogenous splenic veins were used as bridge vessels in 6 cases, whereas the coronary vein and inferior vena cava were anastomosed directly in 9 cases. All surgical patients were followed up from 5 months to 10 years with an average of 63 months; 2 patients died due to liver failure induced by reactivation of hepatitis B virus and oesophageal/gastric variceal rebleeding, respectively. The rebleeding rates for surgical and non-surgical patients were 6.7% and 66.7% (p < 0.05), respectively, whereas the 5-year survival rates for the two groups were 85.7% and 33.3% (p < 0.05), respectively. Patients with oesophageal and gastric variceal bleeding caused by portal hypertension may benefit from a coronary-caval shunt combined with partial pericardial devascularisation due to decreased coronary vein pressure, unaffected hepatic blood inflow, and reduced incidence of rebleeding.
