Abstract
Background
One anastomosis gastric bypass (OAGB) is recognized as a standard procedure in metabolic surgery. However, concerns about postoperative bile reflux and nutritional risks are prevalent. Comparatively, sleeve gastrectomy with loop duodenojejunal bypass (SG + LoopDJB) bypasses an equivalent length of the foregut as OAGB while maintaining pyloric function. The role of pylorus function remains to be further elucidated regarding these metabolic procedures’ therapeutic outcomes and side effects.
Method
A retrospective study was conducted in our center to compare the surgical safety and 1-year outcomes of OAGB and SG + LoopDJB regarding type 2 diabetes mellitus (T2DM) remission, weight loss, gastrointestinal disorders, and nutritional status in T2DM patients matched by gender, age, and BMI.
Results
The baseline characteristics were comparable between groups. Compared with OAGB, SG + LoopDJB had longer operative time and length of stay (LOS) but similar major postoperative complications. At 1-year follow-up, OAGB has similar diabetes remission (both 91.9%), weight loss effect (28.1 ± 7.1% vs. 30.2 ± 7.0% for %TWL), and lipidemia improvement to SG + LoopDJB (P > 0.05). However, OAGB presented a higher incidence of hypoalbuminemia (11.9% vs. 2.4%, P = 0.026) but a low incidence of gastroesophageal reflux disease (GERD) symptoms (9.5% vs. 26.2%, P = 0.046) than SG + LoopDJB. There was no statistical difference regarding other gastrointestinal disorders and nutritional deficiencies between groups.
Conclusion
Both OAGB and SG + LoopDJB show comparable, favorable outcomes in weight loss, T2DM remission, and lipidemia improvement at the 1-year follow-up. Pylorus preservation, while increasing surgical difficulty and the risk of de novo GERD, may reduce the risk of postoperative hypoalbuminemia.
