Identification of Promising Prediction Models for Morbidity and Mortality After Esophagectomy

A systematic review identified 33 prediction models for morbidity and mortality after esophagectomy, with 18 newly developed. Prognostic accuracy ranged from 0.51 to 0.85, with some models showing promise for further development. Performance status emerged as a potential modifiable risk factor, but none of the models are ready for clinical implementation. Two models for mortality and one for pulmonary complications have potential for future refinement. Availability of rigorous prediction models remains limited, with many studies showing a high risk of bias.
