Patients and methods: Descriptive and analytical studies based on the retrospective collection of data on 125 patients’ records in the hepatogastroenterology unit of the University Hospital Campus of Lome (Togo) from January 1, 2008 to March 31, 2018 were included. Cirrhotic patients aged 15 years and older had performed cytochemical analysis of ascites fluid and upper gastrointestinal fibroscopy and had a protidogram. Statistical analysis was done by R Studio Software 3.4.2. Results: The mean age was 48.70 years;there was a male predominance (70.40%) with a sex ratio of 2.38. Protein levels in ascitic fluid was Conclusion: Our study noted that at an upper threshold of 1.10 g/dl, the SAAG significantly predicted the presence of EV.展开更多
