“…Its advantages include a brief operative period, solitary anastomosis, satisfactory short-term complication rates, and successful weight loss. Furthermore, the outcomes of such procedures are non-inferior to those of revisional RYGB [ 13 ]. This study aimed to examine the results of RYGB and OAGB as revision surgeries after unsuccessful SG.…”

Purpose This study aimed to assess the outcomes of revisional procedures, namely Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) following unsuccessful laparoscopic sleeve gastrectomy. Materials and Methods This systematic review and meta-analysis included 817 patients (404 in OAGB group, 413 in RYGB group) from seven retrospective comparative studies. Data on sample size, demographics, perioperative complications, operative time, pre- and post-revisional body mass index, total weight loss, and global weight loss over follow-up were extracted. Results The mean operative time was 98.2–201 minutes for RYGB versus 78.7–168 minutes for OAGB. Despite classical RYGB gastric bypass taking longer, mini gastric bypass resulted in greater weight loss than RYGB, with a mean difference of −5.84 (95% confidence interval [CI], −6.74 to −4.94; P<0.00001; I 2 =0%), greater total weight loss, and a higher diabetes remission rate (odds ratio [OR], 0.32; 95% CI, 0.14 to 0.71). However, OAGB was associated with a significantly higher incidence of postoperative gastroesophageal reflux than RYGB (52 vs. 31: OR, 0.40; 95% CI, 0.24 to 0.67; P=0.0005; I 2 =0%). Conclusion OAGB was performed more quickly and boasted greater total weight loss and higher diabetes remission rates compared to RYGB after failed sleeve gastrectomy. However, OAGB also demonstrated a higher incidence of postoperative gastroesophageal reflux disease. Thus, careful patient selection is essential when considering OAGB.

“…[12] Dayan et al reported GERD resolution and PPI cessation in 77.4% of patients following cOAGB, however, this is in comparison to 91.5% of patients following cRYGB, 32.4 months postoperatively. [31] Similarly, Rayman et al found that the incidence of GERD was signi cantly higher in patients who underwent cOAGB compared to cRYGB (17.4% vs 7.6%, p = 0.018) at one year following surgery. [32] Re ux should be noted as a potential ongoing issue postoperatively in all conversional bariatric procedures.…”

Introduction Conversional bariatric procedures are increasing, particularly conversional one-anastomosis gastric bypasses (cOAGB). This study reports long-term and patient-reported outcomes for cOAGB after laparoscopic adjustable gastric banding (LAGB) and sleeve gastrectomy (SG). Methods This retrospective single-cohort review of a prospective database examined all cOAGB cases (2016-2023). Perioperative morbidity, long-term surgical or endoscopic interventions, and patient-reported outcomes were analysed. Results Within the largest published cohort of 261 consecutive cOAGB patients, 60.9% had prior-LAGB and 39.1% had prior-SG. Within 30 days, three severe and 13 low-grade complications occurred without mortality, with 98.9% of patients home the following day. Twenty-four longer-term surgical interventions were performed for reflux, port-site hernia, perforated ulcer or adhesions. 14 cases of anastomotic ulcer and one reflux oesophagitis were managed conservatively. 60.9% of patients responded to the survey (35.7 months post-cOAGB). 37.1% reported heartburn and 23.9% reported regurgitation. 81.8% of patients reported they were happy with the procedure, and 78% reported they would choose it again, both outcomes associated with greater percentage excess weight loss (%EWL) and lower heartburn scores. Higher satisfaction was associated with less regurgitation or prior-LAGB. Mean BMI (41.8 months after conversion) was 31.5kg/m2 (9.7kg/m2 less than before conversion), with mean %EWL of 64.6% (significantly higher in female patients) and mean TBWL of 22.5%. Conclusion cOAGB was found to be safe and effective for further weight loss or persistent reflux. Although these issues may not be fully resolved, the relative improvement is reflected in the strong satisfaction scores, supporting the use of this technique in conversional surgery.
