Objective: Demonstrate that the increase in ultrasound findings is associated with the risk of developing variceal gastrointestinal bleeding in cirrhotic patients. Material and methods: A retrospective case-control study was conducted on a total population of 82 patients diagnosed with liver cirrhosis (CIE K74.6), without specifying the etiology. However, patients with liver carcinoma, chronic kidney disease, lymphoma, morbid obesity, portosystemic shunt, infectious process that could alter the splenic longitudinal axis, Budd-Chiari syndrome, and other veno occlusive diseases were excluded. A simple random sampling was carried out from this population; 41 of them corresponded to the cases, who presented with variceal gastrointestinal bleeding diagnosed by upper digestive endoscopy, and 41 to the controls, who did not have this diagnosis. All patients had a report of abdominal ultrasound findings where the splenic longitudinal axis and the diameter of the portal vein were evaluated to determine if their increase could be associated with the risk of developing variceal gastrointestinal bleeding. Additionally, a ROC curve was used to determine the predictive capacity for the development of bleeding for both ultrasound findings. Results: The study determined that a portal vein diameter greater than 12mm showed statistical significance (p=0.02) for the occurrence of variceal gastrointestinal bleeding in cirrhotic patients. However, a splenic longitudinal axis greater than 13 cm did not show a statistically significant association (p=0.068) for the occurrence of variceal gastrointestinal bleeding. Additionally, logistic regression analysis revealed area under the curve (AUC) values of 0.642 ([CI] 0.523-0.761; p=0.027) for the portal vein diameter and AUC values of 0.646 ([CI] 0.525-0.767; p=0.027) for the splenic longitudinal axis. When estimating the p-value, it was observed that both the portal vein diameter (p=0.027) and the splenic longitudinal axis (p=0.023) have a predictive utility for gastrointestinal bleeding due to esophageal varices in patients with liver disease. Conclusions: The portal vein diameter and the splenic longitudinal axis were greater than 12mm and 13cm, respectively, in cirrhotic patients with gastrointestinal bleeding from esophageal varices. However, only the portal vein diameter showed statistical significance for the development of variceal bleeding. Additionally, it was demonstrated that both the portal vein diameter and the splenic longitudinal axis have predictive value for the development of gastrointestinal bleeding in cirrhotic patients
