Purpose: Our prospective, randomized clinical study aims to evaluate the utility of intraoperative transesophageal echocardiography (TEE) in patients undergoing radical cystectomy. Materials and Methods: Eighty patients were randomized to a standard of care group or the intervention group that received continuous intraoperative TEE. Data are presented as means ± standard deviations, median (25th percentile, 75th percentile), or numbers and percentages. Characteristics were compared between groups using independent sample t-tests, Wilcoxon–Mann–Whitney tests or Chi-square tests, as appropriate. All tests were two-sided and P < 0.05 was considered to indicate statistical significance. Results: Both groups had similar preoperative demographic characteristics. There was a significant difference between central line insertion with all insertions in the control group (15%, 6 vs. 0%, 0; P < 0.003). Of all the perioperative complications, 80% occurred in the control group versus 20% in the TEE group, with 21% of controls experiencing a cardiac or pulmonary complication compared to 5% in the TEE group (8 vs. 2, P < 0.04). The control group patients were more likely to have adverse cardiac complications than the TEE group (15%, 6 vs. 3%, 1; P < 0.040). Postoperative cardiac arrhythmia was observed only in the control group (13%, 5 vs. 0%, 0; P <.007). Prolonged intubation was only observed in the control group (10%, 4 vs. 0%, 0; P < 0.017). Conclusion: TEE can be a useful monitoring tool in patients undergoing radical cystectomy, limiting the use of central line insertion and potentially translating into earlier extubation and decreased postoperative cardiac morbidities.
