Obesity Surgery, 2026
Background Sleeve gastrectomy (SG) is the most frequently performed metabolic and bariatric surgery (MBS) worldwide, but long-term suboptimal weight loss (SOWL) or recurrent weight gain (RWG) affects up to one third of patients and often necessitates revisional procedures. One-anastomosis gastric bypass (OAGB) is an effective revision, yet pouch dilation and late RWG remain concerns. Ring augmentation (RA) has been proposed to enhance restriction and sustain weight loss, but evidence in the revisional OAGB setting is limited. Methods This retrospective comparative cohort study analyzed 94 adults who underwent revisional OAGB after SG at a high-volume tertiary MBS center. Patients were grouped into two categories: Ring Augmented OAGB (RaOAGB) ( n = 45) and Non-Ring Augmented OAGB (NRa-OAGB) ( n = 49). The primary outcomes were percentage excess weight loss (%EWL), percentage total weight loss (%TWL), and change in body mass index (BMI) at 3, 6, and 12 months. Secondary outcomes included improvement of obesity-related conditions, metabolic parameters (lipid profile, HbA1c), nutritional markers, operative time, hospital stay, and early/late complications. Results Both groups achieved significant weight reduction at 12 months ( p < 0.001 within groups). RaOAGB yielded greater BMI reduction (27.6 vs. 32.2 kg/m²), %EWL (81.7% vs. 61.3%), and %TWL (31.5% vs. 24.2%) compared with NRa-OAGB (all p < 0.001). Lipid profiles improved in both groups; LDL decreased, and total cholesterol equalized by 12 months. Glycemic control changes were modest and similar between cohorts. Operative time, length of stay, and early postoperative complications were comparable. Ring-related adverse events were infrequent (food intolerance 6.7% vs. 4.1%; no erosions were observed; one patient (2.2%) required ring removal at 10 months due to persistent vomiting and food intolerance). Conclusions RaOAGB is a safe and effective revisional option for RWG and SOWL after SG, achieving significantly greater 1-year weight loss than standard OAGB, with uncommon ring-related adverse events, including one ring removal. These findings support the role of mechanical reinforcement to enhance the durability of revisional bypass but warrant confirmation through long-term, multicenter randomized trials.

Ring-Augmented Versus Non-Ring Augmented Sleeve Gastrectomy in Patients with BMI > 50 kg/m²: 3-Year Follow-up of a Randomized Controlled Trial
Mohamed Hany, Walid El Ansari, Mohamed H. Zidan, Anwar Ashraf Abouelnasr, Mohamed Ibrahim, et al.
Obesity Surgery, 2026
Background Sleeve gastrectomy (SG) is effective but prone to late recurrent weight gain (RWG). Ring-augmented SG (Ra-SG) may preserve restriction and enhance long-term durability. Methods In this single-center, prospective, single-blind randomized trial, adults with a BMI > 50 kg/m² were randomized to SG or Ra-SG and followed for 36 months. The primary endpoint was percent total weight loss (%TWL) at 36 months. Secondary outcomes included RWG, gastric pouch volumetry, relapse of associated medical problems, complications, endoscopic findings, laboratory parameters, and patient-reported outcomes (SF-36, Suter). Results Ra-SG produced significantly greater weight loss at 36 months (48.8 ± 8.3 vs. 45.5 ± 9.0%TWL; mean difference 3.25% points, 95% CI 0.86 to 5.63; p 0.008). Exploratory analyses showed lower rates of clinically significant RWG (≥ 30% regain: 5.9% vs. 16.3%; absolute risk difference − 10.4%, 95% CI − 19.6 to − 1.2; p = 0.033) and smaller pouch volumes (160.1 ± 8.9 vs. 194.2 ± 10.3 mL; p < 0.001). Perioperative complications were infrequent and comparable. At three years, the prevalence of endoscopic GERD was similar (17.3% vs. 19.6%). Food tolerance scores were consistently better after SG (all p < 0.05). HRQoL improved significantly in both groups, with no differences observed at 36 months. Two Ra-SG patients (1.8%) underwent ring removal. Conclusions Ra-SG enhanced weight-loss durability and lowered RWG compared to SG, with similar safety and GERD outcomes but decreased food tolerance at mid-term. Ra-SG may be considered in patients at higher risk of RWG, though multicenter studies with longer follow-up are needed to confirm these findings.

Obesity Reviews, 2026
Background Obesity negatively impacts male sexual function and fertility through hormonal imbalances, endothelial dysfunction, and psychosocial factors. Metabolic and bariatric surgery (MBS) constitutes an effective intervention; however, procedure‐stratified changes in male reproductive parameters after Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) remain incompletely synthesized. Methodology A systematic search of PubMed, Embase, Cochrane Library, Scopus, and Web of Science was conducted in November 2024. Sexual function, testosterone levels, and semen quality were included. Risk of bias was assessed using MINORS criteria. Random‐effects meta‐analyses were performed separately for each surgical modality, with heterogeneity quantified via I 2 statistics. Results Twenty‐one studies comprising 848 patients were included. Meta‐analysis of pre–post data demonstrated that both RYGB and SG were independently associated with improvements in sex hormone–binding globulin and testosterone levels. In studies examining SG, significant improvements were observed in erectile function (SMD: 1.38, 95% CI: 0.66–2.10, p = 0.0002) and sperm concentration (SMD: 0.91, 95% CI: 0.56–1.26, p < 0.00001). Studies evaluating RYGB did not demonstrate statistically significant changes in erectile function (SMD: 0.62, 95% CI: −0.06 to 1.30, p = 0.07) or sperm concentration (SMD: −0.01, 95% CI: −0.45 to 0.42, p = 0.95). Conclusion The meta‐analytical findings suggest beneficial effects of both RYGB and SG on male hormonal parameters. Studies of SG demonstrated significant improvements in erectile function and sperm concentration. However, direct comparative analyses between the two procedures were not performed, precluding definitive conclusions regarding their relative efficacy. Future research necessitates head‐to‐head comparisons with standardized reproductive endpoints and extended follow‐up periods.
