About

This study is based at the National Integrated Traditional Chinese and Western Medicine Medical Center and leverages the centralized strengths of our department, which integrates multiple disciplines (general surgery, endocrinology, nutrition, exercise, and traditional Chinese medicine). It focuses on key scientific issues in the comprehensive management of bariatric surgery throughout the entire treatment cycle. By recording key indicators of patients before and after surgery and using methods such as machine learning to predict postoperative complications, we aim to enhance precision management. Ultimately, we will establish a refined diagnosis and treatment system for metabolic weight loss surgery, promote its application, and thereby raise the standardized management level of weight loss and metabolic disciplines in our hospital and primary care units nationwide. This will improve patient outcomes and reduce the healthcare burden.
