Non-adherence to the rule of 3 does not increase the risk of adverse events in esophageal dilation

Non-adherence to the rule of 3 does not appear to increase the risk of AEs, particularly perforation, after esophageal dilation using bougie dilators. Caution is needed with the dilation of malignant strictures, as there is an increased risk of perforations and AEs. However, large prospective studies are needed to verify the results of this study.
