The operation

What a mini gastric bypass is

The stomach is divided to form a long, narrow pouch. A loop of small intestine is brought up and joined to it with a single connection, so food bypasses the first part of the bowel. You eat less, absorb less, and the gut hormones that drive hunger and blood sugar change.

1

One join, not two

The classic Roux-en-Y bypass needs two connections. The mini bypass needs one, which shortens the operation and removes one site where a problem can occur.

2

Strong effect on diabetes

Like every bypass, it improves type 2 diabetes quickly, often before much weight has gone.

3

Fewer deficiencies than Roux-en-Y

In the surgeon's experience deficiencies are much less of an issue than after a classic Roux-en-Y, and the lifelong supplement need is lower. Vitamins and periodic bloods remain part of life after any bypass.

4

The usual revision operation

When a sleeve has stretched or caused reflux, or when a gastric band is removed, the conversion we most often perform is to a mini bypass.

You do not have to choose. Send your details and the surgeon tells you which operation he would do and why. For revision patients the final decision is made after an endoscopy on arrival, because what the stomach looks like matters more than what was planned by message.

Band out, mini bypass in: Jacqueline's experience

Jacqueline in her hospital room in İzmir after gastric band removal and mini gastric bypass surgery

Jacqueline: gastric band removal and mini gastric bypassFilmed in her hospital room in İzmirJacqueline's gastric band removal and mini bypass video – key moments →

Jacqueline had a gastric band that no longer worked. It was removed and converted to a mini gastric bypass in one operation, which is how most band conversions are done here. Two stages are only needed when a band has eroded into the stomach.

Band removal with conversion to a mini bypass is £3,800 and takes about two and a half hours; conversion to a sleeve is £3,500 and takes about two hours. The port and tubing under the skin come out in the same operation. More on the revision surgery page.

Questions and answers

How much does a mini gastric bypass cost in Turkey?

With Op. Dr. Volkan Arayıcı a mini gastric bypass is £2,999, all-inclusive: tests, operation, four nights in hospital, companion, transfers, interpreter, medication and twelve months of follow-up. Only flights are extra.

What is a mini gastric bypass?

A one-anastomosis gastric bypass (OAGB): a long, narrow stomach pouch is created and joined to a loop of small intestine with a single connection. The classic Roux-en-Y bypass uses two connections.

Is a mini gastric bypass worth it?

For the right patient, yes: it gives bypass-level weight loss and diabetes improvement with one join instead of two. It is our usual choice when a sleeve has stopped working or when a gastric band is converted to a bypass.

Mini bypass or Roux-en-Y: what is the difference for me?

With the mini bypass, nutritional deficiencies are much less of an issue than with the classic Roux-en-Y, and the lifelong supplement need is lower. The Roux-en-Y remains the better choice in some patients with severe reflux. The surgeon decides between them from your details; the price is the same.

Is it riskier than a sleeve?

Slightly, because there is an intestinal join. That is why the hospital stay is not shortened: four nights, exactly as for a sleeve.

Can a mini bypass cause bile reflux?

A small share of patients develop bile reflux after a one-anastomosis bypass. If it becomes troublesome it can be converted to a Roux-en-Y. It is one of the things the surgeon weighs before recommending the operation.

How long do I stay in Turkey?

Five days: arrival and bloods on day one, tests and surgery on day two, four nights in hospital, discharge and airport on day five.

Is a mini bypass the right operation for you?

Height, weight, age, and whether you have reflux, diabetes or a previous operation. The surgeon tells you which operation he would do, free and without obligation.
