“…30,31,38 OAGB has been reported as a primary and revision safe and effective procedure, and based on previous reports, OAGB represents 4.5% of the over 685,000 bariatric procedures performed annually across the globe. 39,40 This tendency might be attributed to its efficacy, shorter learning curve, simplification of technical complexity (one anastomosis), lower complications rates, and the alternative for either revisions or conversions if required in the future. 30,41,42 After nearly two decades of experience and the growing expectations of this procedure, the ASMBS granted the appraisal to OAGB as a procedure with short operative time, low complication rates, and excellent weight loss outcomes.…”

The most effective long-term treatment for severe obesity is bariatric surgery with improvement or resolution of obesity-related comorbidities. Single-anastomosis procedures including single-anastomosis duodenoileal bypass and one-anastomosis gastric bypass are relatively new procedures that are gaining popularity worldwide. These surgical techniques are perceived to be less complex with a shorter learning curve in comparison to the standard biliopancreatic diversion with duodenal switch and Roux-en-Y gastric bypass; however, long-term outcomes and complications remain controversial. This article aims to review one-anastomosis procedures, evaluate their outcomes, and review potential complications.

“…In the last decade, due to very promising results, the OAGB has been implemented more frequently [8]. There are indications that the OAGB is superior to the RYGB in terms of the incidence of postoperative dumping syndrome [9]. However, data directly comparing these procedures is limited.…”

Background: Dumping syndrome (DS) is an important but often missed problem occurring after bariatric surgery. It is believed that gastric bypass procedures like Roux-en-Y Gastric Bypass (RYGB) and One-Anastomosis Gastric Bypass (OAGB) are more likely to cause DS than the pylorus-preserving Sleeve Gastrectomy (SG). The aim of this study was to evaluate the incidence of DS in patients undergoing SG, RYGB and OAGB. Methods: A retrospective clinical study with additional phone interviews of 180 morbidly obese patients (130 females; 72.2%) undergoing SG (n=50), RYGB (n=53) and OAGB (n=77) in our clinic during 2016 - 2018 was performed. Clinical and demographic data were assessed. The incidence of dumping syndrome was evaluated using validated Sigstad Score. Results: Information about the occurrence of dumping symptoms and patient satisfaction was obtained from 127 patients; 53 could not be reached by phone. Median follow-up was 20.0 ± 11.4 months. Significant differences between the surgical procedures were found for the duration of surgery, complications, incidence of DS and satisfaction postoperatively. DS occurred in 15.6% after SG, in 56.4% after RYGB and in 42.9% after OAGB. While SG showed the shortest operative time with 66.5 ± 25.3 minutes and highest patient satisfaction, the lowest complication rate was observed after OAGB with 5.2%. The RYGB group reported the longest duration of surgery with 121.0 ± 28.9 minutes, most complications (17.0%), and lowest patient satisfaction. Conclusion: The present results showed a clear superiority of SG regarding both perioperative results and incidence of DS compared to RYGB and OAGB and may impact clinicians and patients in their choice of procedure.

“…A suitable approach in SSO patients is the One Anastomosis Gastric Bypass (OAGB), that is comparable to LSG in safety and might yield superior results regarding weight loss and remission of comorbidities [13][14][15][16][17][18][19][20]. OAGB has been reported to be safe in SSO patients with a BMI > 60 kg/m 2 [13,21] and seems to be even superior to RYGB in terms of reduced complications [22] and improved weight loss [21]. While data on the comparison of OAGB and LSG in patients with morbid obesity is still scarce [18,19,[23][24][25], it is almost absent for SSO patients with the exception of a small retrospective cohort analysis [26].…”

Background Bariatric surgery in super-super-obese (SSO) patients remains a continuous challenge due to intraabdominal fat masses, higher liver volume and existing comorbidities. A convenient procedure in SSO patients is one anastomosis gastric bypass (OAGB). The aim of this study was to compare the outcome of SSO patients undergoing OAGB in comparison to laparoscopic sleeve gastrectomy (LSG). Methods We retrospectively reviewed data from SSO patients who underwent OAGB and LSG in our institution between 2008 and 2020. Primary endpoints included percentage total body weight loss and percentage BMI loss at 12, 24, and 36 months after the operation. Secondary endpoints were perioperative complications, procedure length, length of hospital stay and outcome of comorbidities. Results 243 patients were included in this study. 93 patients underwent LSG and 150 underwent OAGB. At any of the time points evaluated, weight loss in patients after OAGB was greater than in LSG patients, while procedure length was significantly shorter for OAGB than LSG (81.4 vs. 92.1 min, p-value < 0.001). Additionally, mean length of hospital stay was shorter in the OAGB group (3.4 vs. 4.5 days, p-value < 0.001). There were more severe complications (Clavien-Dindo ≥ 3a) in the LSG group (11.8% vs 2.7%, p-value = 0.005). Conclusion In this retrospective analysis, OAGB was superior to LSG in terms of weight loss in SSO patients. Procedure length and hospital stay were shorter after OAGB in comparison to LSG and there were fewer severe complications. OAGB can therefore be regarded a safe and effective treatment modality for SSO patients.
