The stomach size is reduced by 70-80% to reduce its storage capacity with the help of Keyhole surgery, so you feel full with small portions. Though it seems like a restrictive procedure, it also induces hormonal changes in the gut to make you feel less hungry.

This procedure is similar to Roux en Y Gastric Bypass but involves forming only one anastomosis between the stomach and jejunum (part of the small Bowel). This procedure induces weight loss similar to RYGB. Some studies have shown better weight loss with this procedure than RYGB.

Roux-en-y gastric bypass is a restrictive-malabsorptive operation for weight loss. It is the second most common procedure in Australia. Usually performed via laparoscopic (Keyhole) or robotic techniques. This procedure induces weight loss through multiple mechanisms and has a higher risk of diarrhoea, malnutrition and vitamin deficiencies.

This procedure has two critical steps: first, performing sleeve gastrectomy, and second, connecting the first part of the Bowel (duodenum) to the small Bowel further downstream (usually leaving only 300 cm of the small Bowel as a common channel for absorption). This procedure induces excellent weight loss but comes with a high risk of chronic diarrhoea and malnutrition.

Revisional bariatric surgery is a follow-up surgery for any reason after the initial bariatric procedure. The main reasons for considering revisional surgery are insufficient weight loss with the initial procedure, complications, and weight regain. Options include converting gastric band to a Sleeve or bypass, or a Sleeve to bypass.

Keyhole Surgery to repair a hiatal hernia is usually a laparoscopic procedure that is generally well tolerated. Surgery aims to bring the stomach back down into the abdomen and then make the hole smaller to prevent the stomach from slipping again into the chest cavity. This is usually supplemented by wrapping the upper part of the stomach around the oesophagus to recreate a valve.

An upper gastrointestinal (GI) endoscopy is a procedure to look at the inside of your oesophagus (gullet), stomach and duodenum using a flexible telescope. Usually done to assess symptoms such as upper abdominal pain, nausea and vomiting, reflux, difficulty swallowing or weight loss.

A colonoscopy is a procedure to look at the inside of your large bowel (colon) using a flexible telescope. Usually done to assess bloating, rectal bleeding, weight loss and suspicion for cancer.

Stenting and internal drains are becoming more common to deal with leak post Bariatric surgery. This avoids major surgery and pain. This means patients do not have to stay in hospital for long and they can start eating early.

Surgery for colon cancer gives the best chance to cure the disease if diagnosed in the early stages. The majority of Colorectal cancer surgeries can be done with a keyhole approach in elective settings.

Surgery to remove Gall Bladder is called Cholecystectomy. A cholecystectomy is usually done by Keyhole approach. The risk of converting to open is less than 0.5%.

Abdominal wall Hernia can occur in the Groin, Central Upper abdomen, belly button and previous surgical incisions site. All hernias should be considered for repair as they become bigger over time. Most hernia repairs are done with mesh as it has been shown to reduce the chance of hernia returning.
