“…Therefore, any procedure a failed SG is converted to must have good potential to cause additional weight loss. For example, Rayman S. et al compared a revision from SG to OAGB and RYGB in 119 and 144 patients, respectively, and found better weight loss but also higher rates of postoperative GERD in the OAGB group [ 18 ]. A study by Bashah M. et al comparing SADI-S to OAGB as revisional procedures after SG for weight recidivism found better weight loss after SADI-S compared to OAGB and also better results in terms of GERD symptoms [ 19 ].…”

“…The improvement or remission of AMP is one of the most important results of any bariatric/metabolic procedure as well as for the patients’ individual life expectancies. In a study by Rayman S. et al comparing OAGB to RYGB as revisional procedures after SG, both groups showed an improvement of AMP; however, there was no significant difference between both operations [ 18 ]. The current study found good additional remission rates after the conversion in all categories of AMP in both revisional procedures.…”

Purpose Sleeve gastrectomy (SG) is the commonest bariatric procedure worldwide but there is also a high conversion rate mainly due to weight regain and gastroesophageal reflux disease (GERD) reported in studies with long-term follow-up. The aim of this study is to highlight benefits and limitations of converting SG patients to Roux-en-Y gastric bypass (RYGB) and one-anastomosis gastric bypass (OAGB). Setting Retrospective cross-sectional-study, medical university clinic setting. Methods This study includes all patients converted from primary SG to RYGB or OAGB by 12/2018 at the Medical University of Vienna. Patients were examined using gastroscopy, esophageal manometry, 24-h pH-metry, and questionnaires. Results Fifty-eight patients were converted from SG to RYGB (n = 45) or OAGB (n = 13). Total weight loss of patients converted to RYGB and OAGB was 41.5% and 44.8%, respectively, at nadir. Six patients had Barrett’s esophagus (BE) after SG. In four out of these six patients, a complete remission of BE after conversion to RYGB was observed; nevertheless, two patients after RYGB and one after OABG newly developed BE. Clinical GERD improved at a higher rate after RYGB than after OAGB. Both revisional procedures improved associated medical problems. Conclusion Conversion to RYGB is probably the best option for patients with GERD after SG. OAGB has shown a low potential to cure patients from GERD symptoms after SG. In terms of additional weight loss and remission of associated medical problems, both procedures studied were equal. Surveillance gastroscopies every 5 years after SG revisions are recommended.

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.

“…This was also the case with SG [27]. Because of the adverse effects of both procedures on patients with reflux, many studies have suggested switching from SG and OAGB to other surgical procedures, such as RYGB [28].…”

Aim of the study: This study investigated whether Sleeve Gastrectomy (SG) or Omega-Loop-Gastric-Bypass (OAGB) has the best benefit in weight loss, perioperative risk, and remission of comorbidities. Methods: 29,407 patients after SG and OAGB were included in the German Bariatric Surgery Registry (GBSR). Outcome criteria were perioperative morbidity, perioperative complications, and remission of comorbidities after one year of follow-up. Results: 15,169 patients had completed 1-year follow-up (770 patients after OAGB and 14,399 after SG). The %EWL was higher for OAGB than for SG (70.4 ± 18.5 for OAGB and 62.4 ± 22.6 for SG; p<0.001). BMI reduction was also a significant difference in favor of OAGB (17.5 ± 5.6 kg/m2 for OAGB vs. 15.5 ± 5.9 for SG; p<0.001). There was no significant difference between the two groups in perioperative complications (p<5%). Significant differences in favor of OAGB were found in remission of hypertension (p<0.001), IDDM (p<0.001), NIDDM (p<0.001), reflux (p<0.001), and sleep apnea (p<0.001). Conclusion: Our analysis showed that OAGB surgery was associated with more significant BMI reduction and weight loss one year after surgery. In addition, OAGB surgery was significantly more effective in improving obesity-related comorbidities. Our results support the performance of OAGB over SG in patients with obesity and comorbidities. However, the contraindications and general condition of the patient should be considered in the context of this.
