Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Metabolic bariatric surgery (MBS) has demonstrated its efficacy in achieving sustainable weight loss and alleviating associated comorbidities. The primary objective of our investigation is to assess the long-term impact and sustainability of weight loss, the remission of T2D as well as risk prediction of cardiovascular events following MBS concerning one-anastomosis gastric bypass (OAGB) and duodenojejunal bypass with sleeve gastrectomy (DJB-SG).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Metabolic bariatric surgery (MBS) offers enduring weight reduction and alleviation of obesity-related comorbidities, including dyslipidemia, type 2 diabetes (T2D), hypertension (HTN), and major adverse cardiovascular events (MACE). Long-term data on one anastomosis gastric bypass (OAGB) and duodenal-jejunal bypass with sleeve gastrectomy (DJB-SG) is lacking, necessitating this investigation. In this multicenter prospectively-collected retrospective observational study, patients with complete follow-up data at various intervals up to 3 years after surgery were included in the final analysis. The study's primary focus was to evaluate the long-term safety, efficacy, and durability of OAGB and DJB-SG in promoting weight loss and T2D remission. Additionally, changes in 10-year and lifetime risks of MACE before and 3-year after surgery were assessed using the Taiwan MACE risk prediction model and the China-PAR project model based on Taiwan national electronic health records and a large Chinese participant dataset, respectively.

Hypothesis: This study contributes to providing valuable information in terms of the impacts of OAGB and DJB-SG on patients with obesity and associated diseases.
