Background and aim: Majority of cirrhotic patients develop varices, the rate of variceal bleeding is 10-30% yearly with ‎death rate from bleeding is 17-57%. esophagogastroduodenoscopy (EGD) is an invasive and ‎unpleasant technique carrying rare but serious complications. We aimed to investigate the serum ‎ascites albumin gradient (SAAG) and portal vein congestion index (PCI) as non-invasive methods ‎for prediction of esophageal varices (EV) in patients with liver cirrhosis‎.
Patients and Methods: ‎‎125 cirrhotic patients with ascites and no past history of EGD were included. Patients were ‎grouped into; Group I: 38 cirrhotic patients without EV. Group II:  87 cirrhotic patients with EV. ‎Patients were subjected to full clinical evaluation, calculation of SAAG, abdominal ultrasound ‎with a duplex study and measurement of PCI, and Esophagogastroduodenoscopy for detection and ‎grading of esophageal varices‎ ‎.‎
Results: Cirrhotic patients with EV had higher SAAG values (1.85 ‎‏±‏‎ 0.24 gm/dl) than cirrhotic patients ‎without EV (1.27 ‎‏±‏‎ 0.15 gm/dl). Additionally, cirrhotic patients with EV showed a higher PCI ‎than those without (0.16 ± 0.02 and 0.12 ± 0.01 respectively). For prediction of EV in cirrhotic ‎patients, SAAG had AUC 0.986 (p < 0.001) with cutoff >1.4 with sensitivity 97.70% and ‎specificity 89.47% and portal congestion index, AUC was 0.974 (p < 0.001) with cutoff >0.135 had ‎sensitivity 90.80% and specificity 94.74%‎‎‎.
Conclusion: SAAG could be used as a non-invasive predictor for the presence of EV in cirrhotic patients along ‎with SAAG cutoff >1.4 requiring clinical attention. Combination of SAAG and PCI had a high ‎ability to predict esophageal varices in cirrhotic patients with AUC 1.000‎‎‎‎‎.
