Gastric Revisional Surgery

What is gastric revisional surgery?

After bariatric surgery, there can be cases of weight regain or insufficient weight loss. Gastric revisional surgery can correct prior weight loss surgery and help you achieve weight loss targets by adding more restriction or malabsorption. There are two potential procedures to consider.

Speak to a weight loss specialist

When is Gastric Revisional Surgery Required?

Gastric revisional surgery is only used to correct previous weight loss surgery. 

In some circumstances, patients opt to have their adjustable gastric band changed to a full gastric bypass.

We often perform revisional history on patients who opted for cheaper surgeries abroad, but now lack the aftercare needed to heal properly and see real weight loss results. 

Benefits of gastric revisional surgery include:

Less need for follow-up appointments
Increased percentage of weight loss results
Enhanced self-confidence
Improvement in health & obesity-related illnesses

Disclaimer


As with any surgical procedure, there are possible risks and complications, including bruising, pain & swelling, reaction to anaesthetic, excessive bleeding, infection, gallstones, deep venous thrombosis (DVT), pulmonary embolism (clot to the lung), internal small bowel hernia, intolerance to certain foods, gastroesophageal reflux disease (GERD), nutritional deficiencies, vomiting, nausea, diarrhoea and death. These are uncommon and we will do everything possible to prevent them from happening.

Occasionally, patients may require an additional corrective procedure after the initial surgery and some patients might fail to lose a significant amount of weight. 10% of patients regain weight within five to ten years as the pouch dilates, hunger returns and malabsorption fades. 40% of patients may require plastic surgery procedures after weight loss has levelled off, to treat loose skin.

Approximately one in six patients may develop symptomatic gallstones after weight loss, which would require a laparoscopic cholecystectomy.

Please speak to your Tonic surgeon to discuss the risks in more detail and any concerns you may have.

“I have struggled with my weight all of my adult life, I have PCOS and every diet I have tried just wasn’t successful.

I have lost over 10 stone and I feel absolutely incredible. I would never have dreamt to have the life that I currently have now.”

“Life before surgery was fake, I had a happy face but was not really happy. I wouldn’t go on lads holidays with my friends or take my kids swimming. 

I have lost over 10 stone and it’s been life changing. I have got my life back. I can now take my kids swimming, go on holiday, do those things that I should have done 10,15,20 years ago.”

“Before I had surgery, I’d always yo-yoed with my weight. I was ashamed because of the size I’d gotten to. I was unable to buy the clothes I wanted to wear. I didn’t feel like the person that I wanted to be nor did my reflection match the person I felt inside. 

The surgery with Tonic has absolutely changed my life. I’ve lost 5 and a half stone, and I am more confident and outgoing.

“Before weight loss surgery, I couldn’t cope with doing anything strenuous and I couldn’t spend time with my children in the way I wanted to. My eating was out of control, and I had been yo-yoing. 

A year out from surgery, I’m a completely different person. Last year, my body fat percentage was in the morbidly obese category. Now, I’m in the healthy weight category.”

“I lost 8.5 stone. I feel like one of the gym girls, I have done a 10k this year and I am signed up to Brighton half marathon next year! I chose Tonic because I saw so many success stories online and because of the aftercare package. You have the dietician, the PT, the psychotherapist and the constant support group from others who have had surgery and the team in the office”

Is Gastric Revisional Surgery Right for Me?

If you have had weight loss surgery in the past, but haven’t achieved your goals or are experiencing complications, revision surgery might be the right option for you.

At Tonic Weight Loss Surgery, we understand and cater to individual patient needs. We aim to support, guide and help you determine which type of revision surgery is best for you.

How revisional surgery works

When revising a surgery, there are two options to consider: a gastric bypass or a gastric sleeve.

A conversion of an adjustable gastric band to a gastric bypass can take place in one procedure. 

It is critical that revisional surgery is carried out within highly experienced centres, such as Tonic Weight Loss Surgery, as there is almost double the risk of major complications than with first-time bariatric surgery.

The whole team at Tonic will be in touch before and after surgery to advise about appropriate preparations and aftercare.

Patients will often need to go on a liver-shrinking diet (800 calories a day), for around two weeks before surgery. After the operation, patients will be advised to go on a specialist diet to help with the healing process. This involves a liquid diet for two weeks, a puréed diet for one to two weeks and soft, easy-to-chew foods for one to two weeks.
