Laparoscopic one anastomosis gastric bypass (OAGB) is a technique of intestinal bypass used for weight loss. It has been known by other names such as Mini-bypass, Omega-loop gastric bypass and Single-anastomosis gastric bypass.
The operation consists of two components: First, a long, narrow, restrictive lesser-curvature gastric pouch; Second, a small bowel (jejunal) bypass with a single join between gastric pouch and small bowel (gastro-jejunal anastomosis). The expected weight loss and comorbidity control seems to be in line with Roux-en-Y gastric bypass.
Your surgeon can explain how we select patients most appropriate for this form of bypass.

What is the process before and after surgery?
See here: The Process Before & After Weight Loss Surgery as well as our Discharge Instructions.
To help support our patients in the post-op phase, we’ve also developed a series of tailored post-surgery cooking and exercise films that are available exclusively to our patients. These are accessible to and suitable for patients from six weeks after surgery.
Is weight loss surgery safe?
Weight loss surgery, known as bariatric surgery, is generally regarded as safe surgery, in appropriately selected patients. Risks are lower than the longer-term risk of dying from heart disease, diabetes and other consequences of carrying more weight than a person’s organs can tolerate.

What about smoking and surgery?
Smoking at the time of any surgery increases complications and risks. This is a well documented fact.
Current smoking status, and even the time since quitting, are factors we take into consideration when planning bariatric surgery. At Sea Change Weight Loss Clinic, our doctors share the firm view that active smoking is a relative contraindication to surgery, and therefore we advise all patients to stop prior to an operation.
Smoking status also affects which surgical procedure we recommend to our patients in many circumstances.
Can I have surgery in a public hospital?
Currently, in Newcastle, weight loss surgery is only offered in private hospitals. Patients without private health insurance can still pursue weight loss surgery and can discuss their options with the practice. Our practice also supports the use of superannuation to help fund weight loss surgery.
