Key Points

This research aims to validate a non-invasive method for quantifying hepatic steatosis and to develop a tool for predicting patient outcomes post operatively.
Development of a nomogram for predicting normalization rates of hepatic steatosis
Utilization of ultrasound-derived fat fraction (UDFF) measures pre-operatively
Analysis of treatment responses following metabolic surgery
UDFF demonstrated strong validity as a tool for quantifying hepatic steatosis
Nomogram effectively identified patients at risk for delayed normalization
Facilitated personalized surgical management strategies and improved follow-up protocols

Abstract

UDFF is a valid, non-invasive tool for quantifying hepatic steatosis and monitoring treatment response. The developed nomogram provides a practical means for the pre-operative identification of patients at risk for delayed normalization, thereby facilitating personalized surgical management and optimizing follow-up strategies.
