Area of Science:

Gastroenterology
Hepatology
Machine Learning in Medicine

Background:

Metabolic-associated steatotic liver disease (MASLD) and cholecystectomy are common in clinical practice.
Cholecystectomy can lead to metabolic changes, sharing pathways with MASLD.
Identifying liver fibrosis risk post-cholecystectomy in MASLD patients is crucial.

Purpose of the Study:

To develop a predictive tool for liver fibrosis risk after cholecystectomy in MASLD patients.
To leverage machine learning for accurate risk stratification.
To identify key clinical factors associated with fibrosis risk.

Main Methods:

Analysis of a MASLD patient database who underwent cholecystectomy.
Development of a predictive model using the extreme gradient boosting (XGB) algorithm.
Evaluation of model performance against other machine learning methods.

Main Results:

The XGBoost model demonstrated high accuracy in predicting liver fibrosis risk.
Platelet level, dyslipidemia, and type-2 diabetes (T2DM) were significant predictive factors.
XGBoost achieved superior balanced accuracy (93.16%) and AUC (0.92) compared to KNN.

Conclusions:

The proposed XGBoost model serves as an effective tool for automatic diagnostic aid in MASLD patients post-cholecystectomy.
Machine learning techniques can significantly improve the identification of liver fibrosis risk.
Early risk identification facilitates timely clinical intervention.
