“…This percentage was comparable to the EWL of 88.2% and 84.1% at 2-years follow-up in two studies by Petrucciani et al 44 and Debs et al, 45 and to the EWL of 79% in a study by Gerges et al 46 evaluating re-OAGB after failure of restrictive procedure. The remarkable difference we found in weight loss outcome (EWL: 86.7% vs 54%) between re-OAGB and re-LSG 2 years after revisional surgery underlines the inferior efficacy of re-adopting a revisional restrictive surgery after an initial failure of primary restrictive surgery, which comes in accordance with two other studies 29,47 that showed a superiority of gastric bypass conversion compared with re-LSG after failure of restrictive surgery. A methodical nutritional follow-up is indispensable post-operatively to monitor the side effects of the malabsorptive aspect of gastric bypass in the long term.…”

IntroductionWeight loss failure after restrictive bariatric procedures initiated the debate about the choice of an adequate revisional intervention, a question still unanswered. While many surgeons went for a conversion to gastric bypass, others opted for re‐trying a revisional restrictive procedure to avoid the side effects of gastric bypass. The objective of our study was to compare weight loss outcome between revisional laparoscopic sleeve gastrectomy (re‐LSG) and revisional one anastomosis gastric bypass (re‐OAGB) for insufficient weight loss or weight regain following primary restrictive bariatric surgery.Materials and MethodsWe included 20 obese patients, with a history of weight regain or insufficient weight loss after primary restrictive surgery, who underwent re‐LSG (eight patients) or re‐OAGB (12 patients) between January 2018 and January 2021. Patients were followed up 2 years after their revisional intervention. Statistics were performed using IBM® SPSS® software for Windows version 21.ResultsIn the re‐LSG group, the average body mass index (BMI) before primary restrictive procedure was 43.7 kg/m2. The average period between the primary and revisional surgery was 12.6 years. Patients had a nadir BMI of 33.2 kg/m2 during that period and reached a mean BMI of 40.6 kg/m2 before re‐LSG. Two years after re‐LSG, the average BMI was 31.5 kg/m2 with a percent of excess weight loss (%EWL) of 54% and percent of excess BMI loss (%EBMIL) of 66.6%. In the re‐OAGB group, the average BMI before primary restrictive procedure was 39 kg/m2. The average period between the primary and revisional surgery was 10.7 years. Patients had a nadir BMI of 30.5 kg/m2 during that period and reached a mean BMI of 36.5 kg/m2 before re‐OAGB. Two years after re‐OAGB, the average BMI was 27 kg/m2 with a %EWL of 86.7% and %EBMIL of 92.6%.ConclusionFor patients with insufficient weight loss or weight regain following primary restrictive bariatric surgery, re‐OAGB has a better effectiveness in weight reduction compared with re‐LSG after a 2‐year follow up.

“…OAGB has become the most common MBS in Israel, with revisional surgeries comprising nearly 15% of all MBS performed in the country [13]. Revisional MBS has become very common as several types of MBS, especially restrictive procedures, are associated with higher rates of insufficient weight loss and weight regain [14][15][16].…”

Background: One anastomosis gastric bypass (OAGB) prevalence is increasing worldwide and shows good mid- to long-term results. Data on long-term outcomes of revisional OAGB (rOAGB) is limited. This study objective is to evaluate the long-term outcomes of patients undergoing primary OAGB (pOAGB) and rOAGB. Methods: A retrospective analysis of a prospectively maintained patient registry at a single-tertiary center. Patients undergoing OAGB from January 2015 to May 2016 were included and grouped to pOAGB and rOAGB. Results: There were 424 patients, of which 363 underwent pOAGB, and 61 underwent rOAGB. Baseline characteristics were insignificantly different between groups except for type 2 diabetes (T2D) rate which was higher in pOAGB (26% vs. 11.5%, p=0.01). The mean follow-up time was 98.5±3.9 months and long-term follow up data was available for 52.5% of patients. The mean total weight loss (TWL) was higher in the pOAGB group (31.3±14 vs. 24.1±17.6, p=0.006), however TWL was comparable when relating to the weight at primary surgery for rOAGB. The rate of T2D and hypertension resolution was 79% and 72.7% with no difference between groups. 13 patients (5.9%) underwent OAGB revision during follow-up, with no difference between groups. Two deaths occurred during follow-up, both non-related to OAGB. Conclusion: OAGB is effective as a primary and as a revisional procedure for severe obesity with good long-term results in terms of weight loss and resolution of associated diseases. In addition, the revisional surgery rates and chronic complications are acceptable. Further large prospective studies are required to clarify this data.
