The Role of Frailty and ASA Classification in Perioperative Risk Stratification for Esophagectomy Patients: A...

Area of Science:

• Surgical Oncology
• Anesthesiology
• Geriatric Medicine

Background:

• Esophagectomy is a complex procedure with significant morbidity.
• Accurate prediction of postoperative complications is crucial for patient management.
• Existing risk stratification tools like mFI-5 and ASA-PS have limitations.

Purpose of the Study:

• To evaluate perioperative risk factors for high morbidity after esophagectomy.
• To assess the predictive accuracy of the modified frailty index (mFI-5) and ASA-PS classification.
• To identify optimal predictors for high morbidity in esophagectomy patients.

Main Methods:

• Retrospective study design.
• Logistic regression analysis to identify predictors of high morbidity.
• Receiver operating characteristic (ROC) curve analysis to evaluate mFI-5 and ASA-PS performance.

Main Results:

• High morbidity rate observed in 48% of patients.
• Significant predictors included ASA class 3 or higher, preoperative chemoradiotherapy, and prolonged ICU/hospital stays.
• ASA-PS demonstrated better overall accuracy than mFI-5, which had high sensitivity but poor specificity.

Conclusions:

• Both mFI-5 and ASA-PS have limitations in predicting high morbidity post-esophagectomy.
• A comprehensive model integrating perioperative factors, especially postoperative variables, is more significant.
• Further research is needed to develop improved predictive models for esophagectomy outcomes.
