Comment on "Impact of preoperative diastolic dysfunction on short-term outcomes following robotic-assisted minimally invasive esophagectomy (RAMIE)".

This commentary addresses the retrospective study by Torabi et al. on the impact of preoperative diastolic dysfunction on RAMIE. While the study found no association with adverse short-term outcomes, concerns remain regarding statistical power, grade stratification, and unadjusted confounders. A broader inclusion of dysfunction severity is needed to clarify its true perioperative clinical significance.
