About Sleeve Gastrectomy

The Sleeve Gastrectomy involves removal of at least 75% of the stomach. This reduces the volume capacity of the stomach and allows for smaller portions and reduced absorption of nutrients to facilitate weight loss.

Find out what our patients think about Sleeve Gastrectomy

A number of patients have been kind enough to share their experience of Sleeve Gastrectomy, here is what they have to say.


Do I Qualify ?

Under current Irish insurance rules, to be eligible for Bariatric Surgery you should have a BMI over 45 or over 40 with weight related medical conditions. Current international guidelines stipulate a BMI of over 40 or over 35 with weight related medical conditions. If you are self paying, the international guidelines will apply. Surgical, Medical, Psychological and Dietary evaluations are all usually required prior to deciding if you are eligible.

What Preparation is Required?

A thorough multidisciplinary evaluation to determine if you are a candidate for Gastric Bypass Surgery or Sleeve Gastrectomy, which includes a nutritional, psychological and consultations from other medical specialists if deemed necessary. In addition you are required to quit smoking prior to surgery.

What Happens if the Operation Cannot be Performed by the Laparascopic Method?

In a small number of patients the laparoscopic method cannot be performed. Factors that may increase the possibility of choosing or converting to the "open" procedure may include a history of prior abdominal surgery causing dense scar tissue, inability to visualise organs or bleeding problems during the operation. When the surgeon feels that it is safest to convert the laparoscopic procedure to an open one, this is not a complication but rather sound surgical judgement. The decision to convert to an open procedure is strictly based on patient safety.

What Should I Expect on the Day of Surgery?

You will arrive at the hospital the morning of the operation. Preparation for surgery includes changing into a hospital gown. Pre-operative medications may be necessary including a blood thinning injection to reduce the risk of clots. You will also meet the anaesthetist in advance of your surgery.

What are the Expected Results after Laparoscopic Bariatric Surgery?

The success rate for weight loss is reported as being slightly higher with the Gastric Bypass than the Sleeve Gastrectomy but both techniques have shown excellent results. Most reports show a 50% or greater excess weight loss after one year. Weight loss generally continues for all the procedures for 18-24 months after surgery. Some weight gain is common about two to five years after surgery.

Pregnancy after Bariatric Surgery ?

Bariatric Surgery can produce a sudden positive change in your fertility. Women who become pregnant after any of these surgical procedures need special attention from their doctors and clinical care team. To protect women and their babies from potential malnutrition, doctors recommend that women not get pregnant until 18 months after Sleeve Gastrectomy or Gastric Bypass Surgery.

Why not Gastric Band?

Long term studies show that the gastric band is not as effective as other weight loss surgeries. Patients have been found to require more surgeries and have lower rates of weight loss.

Total Patient Care

You will usually be in the hospital for 2-4 days after a laparoscopic procedure. You may have a tube in your nose on the first day, out of bed sitting in a chair the night of surgery and walking by the following day.

You will need to participate in breathing exercises and chest physio & will receive pain medication when required.
