About Gastric Bypass
The Gastric Bypass procedure involves dividing the stomach and forming a small gastric pouch. The new gastric pouch is connected to varying lengths of your own small intestine constructed into a Y-shaped limb (Roux-en-Y gastric bypass).
Gastric bypass surgery thus both reduces portion sizes as well as gently limiting calorie absorption, to allow for enhanced weight loss.
The health benefits of Gastric Bypass include:
- 70 -75% average estimated excess body weight loss
- Approximately 70% reversal of Diabetes
- 60 % resolution of sleep apnoea
- Improved mobility
- Resolution of acid reflux
- Improved fertility for females
Advantages of the Laparoscopic Approach:
- Reduced post-operative pain
- Shorter Hospital Stay
- Fewer Wound Complications
- Return to work 2-3 weeks
Find out what our patients think about Gastric Bypass
A number of patients have been kind enough to share their experience of Gastric Bypass Surgery, 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 Sleeve Gastrectomy or Gastric Bypass Surgery, 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 Laparoscopic 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 Happens 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.
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.
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.
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.Read more
