Nomogram for Predicting 5-Year Diabetes Remission After Roux-en-Y Gastric Bypass Surgery in Chinese Patients with Obesity.

Purpose: Roux-en-Y gastric bypass (RYGB) is widely used as an effective treatment for type 2 diabetes (T2D) patients with obesity; long-term (> 5 years) diabetes remission (DR) rates have been less frequently reported. To date, there is no validated model to guide procedure selection based on long-term glucose control in patients with T2D. The purpose of this study is to establish a new tool for predicting long-term DR with a nomogram.

Comparison of Four Risk Prediction Models for Diabetes Remission after Roux-en-Y Gastric Bypass Surgery in Obese Chinese Patients with Type 2 Diabetes Mellitus.

Background: Roux-en-Y gastric bypass (RYGB) is a major type of bariatric surgery. Various models have been established for facilitating clinical decision-making and predicting outcomes after RYGB; the ABCD, DiaRem, advanced-DiaRem (Ad-DiaRem), and DiaBetter scores are among the most commonly used risk prediction models. However, these models were primarily developed based on retrospective analyses of patients from Western countries at 1 year after RYGB.
