Bleeding Outcomes Following Transesophageal Echocardiography in Patients With Cirrhosis and Esophageal Varices

Despite scant evidence, current guidelines indicate that esophageal varices are a relative contraindication to transesophageal echocardiography (TEE). The aim of this study is to compare the risk of gastrointestinal bleeding following TEE among cirrhotic patients with and without endoscopically‐documented esophageal varices. This is a retrospective analysis of patients with cirrhosis who underwent upper endoscopy within 4 years of TEE at five institutions between January 2000 and March 2020. Primary outcome was overt gastrointestinal bleeding. Secondary outcomes were hemoglobin decline by at least 2 g/dL or blood transfusion within 48 hours following TEE. Of the 191 patients, 79 (41.4%) had esophageal varices (30.4% large). No patient experienced a primary outcome. Secondary outcomes occurred in 52 (27.2%): 28 (35.4%) with esophageal varices and 24 (21.4%) without varices. After propensity‐score covariate adjustment, the odds ratio for a secondary outcome in patients with esophageal varices was 1.49 (95% confidence interval 0.74‐2.99). Restricting analysis to those who underwent endoscopy within 1 year of TEE did not significantly alter results. The risk of a secondary outcome was identical between patients who had upper endoscopy prior (27.5%) versus subsequent (26.7%; P = 1.00) to TEE. Conclusions: Among patients with cirrhosis, there was no overt gastrointestinal bleeding after TEE. The likelihood of a 2 g/dL decline in hemoglobin or blood transfusion within 48 hours following TEE was not significantly higher in patients with esophageal varices after controlling for confounders. Patients who underwent upper endoscopy before TEE did not manifest a lower risk of secondary outcomes versus those who had endoscopy after TEE, suggesting that routine preprocedural endoscopy is of marginal utility.
