Accurate patient evaluation is essential to appropriate patient for DSRS. This depends on endoscopy for oesophageal varices grading and detection of risk factors of rebleeding, Duplex study for assessment of patency of splenic vein, flow volume, velocity and also for portal, superior mesenteric veins and hepatic, splenic arteries, anatomy and position of the left renal vein. Assessment of the liver status based on Child-pugh classification
