Abstract
Portal hypertension is usually associated with splanchnic vasodilatation with increased portal venous flow This is thought to be of major importance in the maintainance of an. increased portal pressure despite the formation of extensive portal systemic collateral circulation This study was carried out on 30 male patients all of them had portal hypertension of proven bilharzial etiology and had endoscopic evidence of esophageal varices, and were prepared to undergo surgical correction by various shunt procedures . They were classified according to the type of operation into splenectomy (5 cases), DSRS (10 cases) and Hassab operation (15 cases) besides 10 healthy control. They were examined and investigated at the time of admission and 2-3 weeks after operation. Liverfunction,kidney function, blood glucose level, insulin, C-peptide and glucagon were estimated. Serum insulin and C-peptide levels before operation were significantly higher than control and after operation they were decreased but were still higher than normal controls. Serum glucagon was significantly.
