Background
A long-lasting and efficient method of managing obesity and therapeutic associated comorbidities is bariatric surgery. However, a debated comparison between one-anastomosis gastric bypass (OAGB) and sleeve gastrectomy is still essential (SG). The goal of this study is to evaluate outcomes using RCT and NRCT from 2015 to 2022.
Methods
By contrasting the OAGB and SG for bariatric surgery from January 2015 to September 2022, an RCT and NRCT were prospectively gathered using the PubMed, Cochrane Library, and MEDLINE databases of published research. This meta-statistical analysis was carried out in RevMan 5.4, and the best effect model was selected based on heterogeneity.
Results
Twelve retrospective studies describing 6344 patients (3725 OAGB and 2619 SG) satisfied the inclusion criteria. A statistically significant result was in %EWL first year (MD = 8.03, 95% CI: 4.54–11.52, P < 0.05), second year (MD = 8.94, 95% CI: 2.95–14.94, P < 0.05), third year (MD = 8.93, 95% CI: 5.75–12.10, P < 0.05), fourth year (MD = 15.09, 95% CI:0.87–29.31, P < 0.05), and fifth year (MD = 14.25, 95% CI: 5.34, P < 0.05). OAGB was associated with a lower rate of remission in dyslipidemia, hypertension, diabetes mellitus, and hemorrhage. However, OAGB increased the incidence of GERD and leakage.
Conclusions
In terms of weight loss and comorbidity remission, OAGB is more effective than SG, although postoperative consequences are rather comparable between the two methods.
