We want to understand how well this surgery works and its effects on patients' health. We'll look at data from adults who had this surgery, tracking everything from before the operation to after they go home and comparing to other types of operation for weight loss. We'll check for any problems during or after surgery, how long they stay in the hospital, and how much weight they lose. We're also interested in seeing if other health issues related to obesity get better. By doing this, we hope to learn more about how effective and safe this surgery is and how it's being used in hospitals across the country", 'detailedDescription': 'Recent reporting from the International Federation for Surgery for Obesity (IFSO) Registry report that the three most common metabolic surgery procedures are sleeve gastrectomy (SG), Roux-en-y gastric bypass (RYGB) and one-anastomosis gastric bypass (OAGB)\\[1\\]. Introduced by Rutledge in 1997\\[2\\], OAGB is now increasing being used in bariatric practice. Recent network meta-analysis indicates OAGB may offer comparable weight loss whilst minimising complications\\[3\\]. Literature published from both the IFSO Registry and the Israeli National Registry indicate increased use of OAGB in the surgical treatment of obesity\\[1, 4\\].\n\nThe safe introduction of new surgical procedures can be confounded by learning effects for both operative technique and perioperative care practices\\[5\\]. No study has yet considered the introduction of OAGB at a population or national registry level.\n\nThe aim of the study is to study the introduction of OAGB into NHS practice in the national bariatric surgery registry.\n\nStudy population: Adult patients undergoing surgery for obesity using one-anastomosis gastric bypass Exclusions: Paediatric cases\n\nData All patient undergoing OAGB operations within the NBSR - pre-operative, intra-operative and postoperative data as described below\n\nOutcome measures Perioperative outcomes Complications Return to theatre Length of stay Percentage of OAGB practice as a proportion of total bariatric surgery practice at individual hospitals\n\nLonger term outcomes Total body weight loss Excess weight loss Remission of comorbidities\n\nReferences\n\n1.
