Mini Gastric Bypass Surgery UK

What is mini gastric bypass surgery?

The mini gastric bypass procedure is the newest bariatric procedure available. In its ten-year life span, it has proven to produce excellent long-term weight loss results. It can be seen as a halfway house between the sleeve gastrectomy and the Roux-en-Y bypass operation.

It’s a simple, short and inexpensive technique, carried out by keyhole surgery under general anaesthetic. The operation usually takes less than 60 minutes and the hospital stay is usually less than one day.

Cost-effective
Healthier lifestyle
Improved self-confidence
Improved health

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.

Is a Mini Gastric Bypass Right for Me?

With excellent long-term weight loss, minimal pain and the option for reversal or revision should the need ever occur, it’s not surprising that people from across the world are choosing the mini gastric bypass over other types of weight loss surgery.

How it works

The mini bypass surgery is undertaken laparoscopically (keyhole). The surgeon will divide your stomach into two parts, your “mini stomach” and your “defunctionalised stomach” (which no longer receives or processes food).

Your small intestine will then be bypassed, with your lower intestine being connected to your new stomach pouch. This shorter digestive system ensures less calories are absorbed into the body.

Results speak for themselves

Most patients typically lose 30–35% of their total body weight in the first nine to twelve months after surgery. The mini bypass will help patients to maintain a steady weight going into the future.

Patients will be nursed on specialist bariatric wards

They can expect to be up and walking within three hours of the operation, drinking the same day and going home the next day. Most patients can expect to be back at work after seven to ten days. After the procedure, patients will be asked to go on a particular diet to help the healing.

Typically, this is a liquid-only diet for two weeks, a puréed diet for two weeks and then a soft diet for two weeks. From then on, patients will need to continue to eat in the right way, adopting an active and healthy lifestyle.

To prepare for the mini gastric bypass, patients will have a consultation with one of our surgeons in the clinic.

The Tonic support team, including our specialist dietitian, psychotherapist and biometric specialist nurse, will be in touch to offer advice and prepare you for your mini gastric bypass.

Part of the preparation may also involve a liver-shrinking diet (800 calories a day) for around two weeks before surgery.
