摘要

One anastomosis gastric bypass (OAGB) is increasingly becoming popular worldwide and is considered a safe and effective procedure. However, data regarding long-term efficacy is lacking. We performed a systematic review of articles reporting outcomes in patients with a minimum follow-up of 10 years. Five retrospective studies comprising 1,750 patients met the inclusion criteria. Overall, the weighted mean percentage of total weight loss was 31.1% ( range 29.6–32.1), and remission rates of type 2 diabetes and hypertension ranged from 70.8 to 90% and 56.7–85%, respectively. Conversion or revisional surgery following OAGB was required in 5.2% ( range 3.3–6.4%) of patients on average. This systematic review suggests that OAGB remains a relatively effective and safe procedure after 10 years.
