Procedure Information
Gastric Sleeve Surgery (Sleeve Gastrectomy)▼
Gastric sleeve surgery, also known as sleeve gastrectomy, is a weight loss operation that involves removing 75-85% of the stomach. The remaining stomach is shaped into a tube, or sleeve, and is about the size of a small banana. It can be done laparoscopically (keyhole).
Gastric Sleeve with Minimizer Ring▼
Gastric sleeve surgery is a popular weight loss surgery that involves removing 75-85% of the stomach. The remaining stomach is shaped into a tube, or sleeve, with an added minimizer ring.
Omega Loop Gastric Bypass with MiniMIZER RING Surgery▼
Omega loop gastric bypass or One Anastomosis Gastric Bypass (OAGB) is a weight loss operation that involves creating a small stomach pouch and reconnecting the small intestine to the pouch.
Roux-en-Y Gastric Bypass (RnY)▼
Roux-en-Y gastric bypass (RYGB) is a weight loss operation that has been performed globally for over 50 years. It has been considered the gold standard for weight loss surgery as all subsequent weight loss operations have been measured against it. A small stomach pouch is created to restrict food intake, and a section of the small intestine is brought up and attached to the pouch to create the bypass reducing calories.
Single-stage Revisional Surgery▼
Single-stage revisional bariatric surgery is a procedure that combines the removal of a gastric band with the conversion to either a gastric sleeve or gastric bypass surgery in the same operation. This surgery is typically performed for patients with previous bariatric surgery who may need re-do surgery for various reasons.
Anti-Reflux Surgery for Weight Loss Surgery Patients▼
Anti-reflux surgery is a surgery that is performed to treat gastroesophageal reflux disease (GORD/GERD), also known as heartburn. GORD is a condition that occurs when stomach acid refluxes up into the oesophagus.
Gallstones & Gallbladder Removal for Weight Loss Patients▼
Gallstones are small, hard deposits that form in the gallbladder, a pear-shaped organ that stores and concentrates bile. Bile is a digestive fluid that helps the body to break down and absorb fat.
Hernia Repair for Weight Loss Surgery▼
A hernia is a condition in which an internal organ or tissue protrudes through a weak spot in the muscle or tissue that normally holds it in place. Hernias can occur anywhere in the body, but they are most common in the abdomen or groin region.
Sydney Bariatric Skin Removal▼
Significant weight loss, whether achieved through bariatric surgery or lifestyle changes, is a remarkable accomplishment. However, it can often leave behind excess skin, which can be both physically and emotionally challenging.
