研究目的:

本研究旨在基于术前常规二维超声图像,融合深度学习与影像组学方法,构建人工智能预测模型,用于术前识别困难腹腔镜胆囊切除术的发生风险。通过系统挖掘超声图像中的定量特征与潜在结构信息,评估模型在预测手术困难程度方面的准确性和稳定性,为术前风险分层、手术策略制定及围手术期管理提供客观辅助依据,提升手术安全性与临床决策水平。  

Objectives of Study:

The objective of this study is to develop and evaluate a preoperative ultrasound-based artificial intelligence model integrating deep learning and radiomics for predicting difficult laparoscopic cholecystectomy. By systematically extracting and analyzing quantitative imaging features from routine preoperative ultrasound images, this study aims to assess the model’s ability to identify patients at high risk of surgical difficulty before operation, thereby providing objective support for preoperative risk stratification, surgical planning, and perioperative management.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection and management in this study consist of two components: Case Record Forms (CRFs) and an Electronic Data Capture (EDC) system.CRFs are used to systematically record demographic information, preoperative ultrasound imaging data, intraoperative surgical findings, and relevant outcome measures. All data are collected by trained investigators according to standardized procedures and are checked for completeness and consistency prior to data entry.Verified data are subsequently entered into the EDC system for centralized management. The EDC system is equipped with role-based access control to ensure data traceability. All study data are de-identified and stored securely, with access restricted to authorized members of the research team. Regular data quality control and data backup procedures are implemented to ensure data security, integrity, and reliability.
