Purpose Revisional bariatric surgeries following laparoscopic sleeve gastrectomy (LSG) have demonstrated a dramatic increase worldwide. Recently, one-anastomosis gastric bypass (OAGB) has become a contender as an appropriate revisional procedure; however, no long-term data currently exist on the effectiveness of it as a revisional surgery post-LSG. Methods A retrospective analysis was performed on all patients who underwent LSG at a public hospital in Kuwait from 2008 to 2017. A list was obtained of those who underwent revisional OAGB surgery after initial LSG, after which a phone survey was performed and demographics were analyzed. Results A total of 29 patients underwent revisional OAGB post-initial LSG, of which 89.7% were female. Prior to LSG, the mean weight of the patients was 127.5 kg, and the mean BMI was 49.0 kg/m 2 . The mean weight loss after initial LSG was 43.8 kg, while the average duration until patients underwent revisional OAGB was 5.3 years. The cause for revision was weight regain (86.2%) or inadequate weight loss (13.8%). Prior to undergoing revisional OAGB, the weight and BMI of the patients was 110.9 kg and 42.4 kg/m 2 , respectively. Revisional OAGB demonstrated a %excess weight loss of 14.5%, 31.9%, 48.0%, 56.3%, 57.2%, and 54.7% at 2 weeks, 3 months, 6 months, 1 year, 4 years, and 5 years, respectively. Twelve morbidities were reported during the follow-up period. Conclusion Revisional bariatric surgery is technically demanding and may be associated with a high complication rate. However, OAGB as a revisional procedure has proven to be safe and effective in the long-term outcomes of revisional OAGB patients post-LSG.
