What is Bariatric Surgery?

Bariatric surgery, also known as metabolic or weight loss surgery, uses advanced laparoscopic (keyhole) procedures to help patients lose weight. It can resolve or significantly improve co-morbidities, such as hypertension, diabetes, sleep apnoea and arthritic pain. Many medical conditions can be successfully treated with significant weight loss.

Bariatric surgery is a medical operation for morbidly obese people to reduce their weight. It stops hunger and satiety by altering the gut hormone levels. Weight loss gained via bariatric surgery establishes a new weight set point.

There are different types of obesity surgery available, and only a qualified and accredited metabolic surgeon, such as Dr Michael Devadas, can tell can you which one is right for you. Dr Michael Devadas helps his patients achieve life-long sustainable weight loss, to improve their quality of life. Your bariatric surgeon should have advanced training or credentials in upper gastrointestinal surgery.

Understanding weight gain

For some reason, some of us just keep putting on weight. Obesity is complex and not simply due to poor choices in life to satisfy cravings and urges. To understand why someone gets to a stage where they need bariatric surgery, you need to understand the connection between weight gain and how the stomach digests food.

Digestion is a complex process. Food gives the body energy by turning what you eat into nutrients. Food also repairs your cells to help your body survive and creates waste to be eliminated. Poor sleep, eating too many processed or sugary foods (like soft drinks – even diet ones – ice cream, chocolate), portion size, sedentary activities, alcohol and the time day you eat are just some of the habits that may increase your risk of weight gain.

A calorie deficit is a good start to help you lose weight. This means that you need to consume fewer calories from the food and drink you have than your body needs. If you eat more energy than you need (over eat), you gain weight. If you eat less energy than you need, you lose weight.

Bariatric surgery is a long-term decision, not a magic fix. After surgery, you need to change your diet and behaviour for the long term.

When should I consider
bariatric surgery?

Dr Michael Devadas sets the criteria you must meet to have bariatric (weight loss) surgery. These conditions are:

  • No smoking
  • BMI (Body Mass Index) over 35 with two weight-related co-morbidities or BMI > 40
  • Being ready to take on a lifestyle change
  • Engaging in Dr Devadas' post-operative follow-up program

Do I need Bariatric (obesity) Surgery?

If you have tried diet and exercise, medications and other programs to lose weight and have not been able to obtain long-term results, then surgery could be the answer for you.

About Dr Michael Devadas

FRACS MBBS (Hons) BAppSC
General and Upper Gastrointestinal Surgeon

Dr Michael Devadas is a Surgical Review Corporation (SRC) accredited Master Surgeon in Metabolic & Bariatric Surgery. The fundamentals of an SRC accreditation are essential to the delivery of safe and effective patient care. Status as an accredited Master Surgeon means Dr Michael Devadas has met internationally recognised standards. Not all surgeons have had an external organisation review and critique their practice and outcomes. Some use the nomenclature without actually undertaking the extensive process.

Healthcare facilities and surgeons seeking an SRC accreditation undergo an extensive assessment and inspection process to ensure the applicant meets SRC’s proven standards and requirements. These requirements include surgical volumes, facility equipment, clinical pathways and standardised operating procedures, with an emphasis on patient education and continuous quality assessment. The assessment includes all staff working within Dr Devadas’ metabolic and bariatric surgical program.

 

About the Surgical Review Corporation (SRC) Accreditation

SRC accredits the top medical professionals and facilities in the world who are dedicated to sustaining a culture of excellence by committing to safety, high-quality surgical care and optimal patient outcomes. This accreditation distinguishes Dr Devadas from many other surgeons for delivering the highest quality of care to patients, as determined by an independent, external process of evaluation.

He is also accredited with Norwest Private Hospital’s Centre of Excellence in Metabolic & Bariatric Surgery as a Surgeon of Excellence. Not all hospitals and surgeons seek this level of accreditation; and not all hospitals and surgeons that undergo the rigorous inspection process are granted accreditation.

Assessors educate staff on best practices, to help an organisation improve its care and services.

 

What does SRC’s gold seal of accreditation mean for you, the patient?

  • SRC is independent and objective. Unlike some accreditation programs, SRC is not part of a medical society that uses its members to evaluate colleagues.
  • The requirements for accreditation programs have been proven to improve outcomes and reduce the time you will spend in hospital.
  • SRC-accredited surgeons dedicate significant time and resources to achieve their SRC endorsement.
  • SRC-accredited surgeons must adhere to meticulous accreditation standards, confirming compliance of these standards through rigorous inspections. Inspections include the evaluation of equipment used for treatment, patient education and support groups, treatment pathways and consultative services.
  • Key members of the treatment team are interviewed.
  • Detailed medical chart reviews are performed to verify the experience of each medical professional applicant and to evaluate whether the care they provide is thorough and complete.

SRC is one of the few organisations that accredits both the medical facility and individual medical professionals. Many programs only accredit the hospital, not the doctor who provides the care, such as Dr Michael Devadas.

There are five types of surgery, and only your surgeon can tell you the right one for you.

1. Gastric Sleeve Surgery

This is the most common and safest form of surgery. Your stomach volume is reduced to approximately ½ - ¾ of a cup size. You will experience a significantly reduced appetite, and improved satiety.

2. Roux-en-Y Gastric Bypass

This is better for patients with significant and debilitating reflux. You cannot have this surgery if you are taking NSAIDs or have been a smoker. Risk is ~5%.

3. Single Anastomosis Gastric Bypass (SAGB)

This surgery is similar to Roux En Y, but has only one join, not two. Can get bile reflux in ~10%.

4. Loop-Duodenal Switch

This surgery constitutes <1% of all bariatric operations. It is high risk in the long term with nutritional deficiencies and significant malabsorption.

5. Revision Bariatric Procedures

This surgery is becoming more common. It constitutes about 30% of Dr Devedas’ cases. These cases usually involve going from a band to sleeve or bypass operations.
