“…3 Forest plot showing the effect of OAGB/MGB on BMI after 1-year follow-up [41]. This review of literature also showed that simultaneous gastric remnant resection, which was performed in some of the studies [21,23,25,26,29], has no significant effects on weight loss, but, in our opinion, it can only increase the risk for postoperative complications and hamper reversal surgery (Table 11).…”

One anastomosis gastric bypass (OAGB/MGB) has gained popularity in the past decade. International databases were searched for articles published by September 10, 2020, on OAGB/MGB as a revisional procedure after restrictive procedures. Twenty-six studies examining a total of 1771 patients were included. The mean initial BMI was 45.70 kg/m2, which decreased to 31.52, 31.40, and 30.54 kg/m2 at 1, 3, and 5-year follow-ups, respectively. Remission of type-2 diabetes mellitus (T2DM) following OAGB/MGB at 1-, 3-, and 5-year follow-up was 65.16 ± 24.43, 65.37 ± 36.07, and 78.10 ± 14.19%, respectively. Remission/improvement rate from gastroesophageal reflux disease (GERD). Also, 7.4% of the patients developed de novo GERD following OAGB/MGB. Leakage was the most common major complication. OAGB/MGB appears to be feasible and effective as a revisional procedure after failed restrictive bariatric procedures.

“…In addition to T2DM remission, this analysis found an improvement in the lipid profile. Some articles did not report the DL outcomes after OAGB/MGB as a revisional operation [17,21,23,26,30]. Nevertheless, a 75% remission rate of DL was reported by Bruzzi et al [24].…”

“…Poghosyan et al showed that the best weight loss outcomes are achieved at 3-year follow-up after conversion of SG to OAGB and will decrease after that 7 . Bhandari et al showed that weight loss continues until 2 years after conversional OAGB and there is a tendency towards weight regain and recurrence of obesity associated medical problems after 3 years 5 . They reported recurrence of DM in one patients at 3-year follow-up, similar to recent study that we found DM recurrence in one patient at 5-year follow-up.…”

“…One Anastomosis Gastric Bypass (OAGB) is a malabsorptive surgery that was first introduced by Rutledge in 1997 and is now the third most common bariatric surgery performed in the world 4 . OAGB has become a simple, feasible and effective conversion procedure for weight loss failure after SG that has satisfying effects on weight and obesity associated medical problems 5 – 7 and can be safely performed in tertiary bariatric surgery centers 8 .…”

The most accepted procedures as conversion for poor weight changes after sleeve gastrectomy (SG), are malabsorptive surgeries. This study was designed to evaluate the 5-year outcomes of One Anastomosis Gastric Bypass (OAGB) following SG due to weight loss failure and weight regain. From September 2014 to January 2017, totally 23 patients with a history of SG conversion to OAGB in terms of weight loss failure or weight regain who had completed their 5-year follow-ups were studied. Some obesity related co-morbidities containing type-2 diabetes (DM), hypertension (HTN), dyslipidemia, obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) were also investigated at 1, 2, 3 and 5 years after conversional surgery. All cases had remission/improvement in DM, DLP, HTN and OSA 1 year after conversional OAGB. Analysis showed statistically significant (P < 0.001) change in trend of BMI. Mean BMI before conversional surgery, at 1, 2, 3and 5 years were 46.3 ± 10.4, 34.5 ± 8.5, 34.1 ± 8.6, 35.7 ± 8.7 and 37.5 ± 11.6, respectively. Mean percent excess weight loss (%EWL) at 1, 2, 3 and 5 years was 51.6 ± 11.0, 52.9 ± 13.1, 45.5 ± 16.4 and 41.0 ± 18.0, respectively. Mean percent total weight loss (%TWL) at 1, 2, 3 and 5 years was 26.6 ± 5.9, 27.4 ± 7.2, 23.9 ± 9.2 and 20.9 ± 9.3, respectively. OAGB is an effective conversional procedure for insufficient weight loss and weight regain following failed SG and lead to satisfactory changes in obesity associated medical problems. The optimal weight loss results are obtained at 2-year follow-ups and these effects are then reduced.
