New tool predicts perforation risks during endoscopic submucosal dissection

A novel predictive model for perforation risk during endoscopic submucosal dissection (ESD) has been developed and validated by researchers. In a study involving 1,051 patients, significant predictors included the first 100 procedures, lesion size over 35 mm, and extended operative time. The model demonstrated satisfactory validation performance with an area under the curve of 0.7078 and accuracy of 80.19%. This tool aims to enhance patient safety and inform preprocedural strategies for clinicians.
