Alternatives to this procedure:

May include persisting with medical therapy.
There may not be any other reasonable surgical alternatives due to reflux being the major problem.

How is the procedure performed?

A gastroscopy is usually performed in the work-up before surgery, sometimes weeks prior or on the day.
Other investigations may also be requested to confirm reflux or assess your surgical anatomy.
Surgery is performed under General Anaesthesia.
The surgery is performed using key-hole surgery and there will usually be 5 small incisions.
Adhesions from previous surgery will be divided to facilitate surgical access and exposure to the surgical site.
The small intestine (biliopancreatic limb) that carries bile past the gastric pouch will be disconnected using a surgical stapler.
It will then be joined back into the small intestine further downstream by approximately 1 metre to prevent bile from flowing backwards up into the gastric pouch and oesophagus, hence resolving the bile reflux. The configuration of the small intestine will be in a format that is known as a "Roux-en-Y" (pronounced ROO-ON-Y).
Occasionally all of the small intestine length will need to be measured to ensure that there is enough small intestine left for absorption.
Occasionally the gastric pouch will need to be shortened to reduce acid production, and the join (anastomosis) between the gastric pouch and intestine will need to be recreated.
Defects in the intestine mesentery will be sutured closed to decrease the chance of getting an internal hernia and twisted bowel, which can be life threatening.
A surgical glue may be used also to prevent bleeding.
A leak test might be performed during surgery, and the blue dye used might give you blue/green urine.
After surgery
- Pain around the wounds and shoulder tip are to be expected following surgery.
- Pain in the left upper part of the tummy is common after Roux-en-Y Gastric Bypass.
- Swallowing fluids and eventually food may feel different after surgery.
- Most patients will be discharged home after 1 or 2 nights stay in hospital.
- You will need to remain on anti-acid medication (Pantoprazole or another proton-pump inhibitor) for 3 months after surgery.
- You will be on vitamin supplements for the rest of your life.
- You will require blood test nutritional monitoring for the rest of your life.
- You will be on a modified post-surgery diet which will be instructed by the dietitian.
- It is recommended that you take two weeks off work to recovery from surgery.
- You will not be able to drive for at least 7 days after surgery. 
If you live more than 1 hour drive from Brisbane, you will need to stay locally in the greater Brisbane Region after surgery for your recovery for at least 10 days after surgery, in case you were to develop early complications.

Declaration Of Understanding *

Dr Wong has explained the indications for surgery, about the procedure to me in language I can understand.I accept the surgery that has been proposed, and other reasonable alternatives have also been considered.I understand the indications for surgery being performed.I understand about the surgery that is to be performed, including pre-operative investigations and recovery after surgery.I understand that I am required to stay locally in Brisbane after surgery for at least 10 days for my own safety.

Potential risks of surgery

Gastric bypass surgery is considered safe and has a very low risk of serious complications. Revision surgery has higher risk than primary surgery. Revision surgery and surgery in smokers, patients on medication that affects healing or blood clotting, or other significant medical conditions may have a higher risk of complications with surgery.

Gastric bypass surgery will usually NOT be offered to patients who smoke because of the risk of complications and marginal ulceration, and if you are a smoker you are required to stop smoking AS SOON AS POSSIBLE. You may be required to prove your commitment to remaining smoke free for a period of time, if you are a recently quit smoker. If you are a smoker and have not discussed this with Dr Wong, you are advised to declare this to a member of Dr Wong's team immediately.

Serious complications - (rare <1%) - the risk of these complications are higher in revision surgery

Damage to other structures or organs.

Major Bleeding.

Staple line leak – which can result in serious illness requiring further interventions.

Anastomotic leak - which can result in serious illness requiring further interventions.

Death

Serious complications can sometimes result in prolonged hospital stay, multiple procedures being required, and a prolonged recovery period, and sometimes temporary or permanent disability. This is rare, but a real risk of having complex major abdominal surgery.

Uncommon complications

Ongoing reflux symptoms. Sometimes symptoms can persist in the absence of reflux actually being present.

Ongoing actual reflux - you should notify Dr Wong and his team as further investigations for other problems may be required.

Difficulty swallowing, or feeling that things don't pass down the oesophagus as well.

Pouch or anastomosis dilatation over time with loss of restriction.

Weight regain.

Poor weight loss or excessive weight loss - the ultimate result varies between people.

Malnutrition – Iron, Vitamin B12, Vitamin D, Zinc, Protein.

Low blood sugars after eating (particularly carbohydrates and sugar).

Internal hernia (twisted bowel) - this can be serious, lifethreatening event and require emergency surgery.

Bowel obstruction

Loose bowel motions (may be more likely with revision surgery as more bowel may be bypassed) or constipation.

Twisting of the gastric pouch.

Narrowing of the gastric pouch or anastomosis between the gastric pouch and intestine which may require endoscopic intervention to dilate, sometimes multiple times.

Relatively common issues encountered by patients

Food intolerances with certain types of food feeling like they get stuck, or cause gastrointestinal upset.

Abdominal pains (especially in the left upper abdomen) with no apparent cause.

Gas bloating,

Dumping - diarrhoea after eating certain foods.

Other General Risks

Wound infection.

Incisional hernia.

Gallstones developing (approx 30%), which may require further surgery.

Venous thromboembolism.

Pneumonia.

Complications related to anaesthesia or medications including a severe allergic reaction.

Other Risks or Complications discussed by Dr Wong

Declaration of Understanding of Surgical Risk *

Dr Wong has gone through the risks of the surgery with me in language that I can understand.I understand that this is a major surgical procedure, and that complications can occur. Whilst these are uncommon or rare, the implications can be significant and can include requiring further interventional procedures, prolonged stay in hospital (weeks or months), long-term disability and even death.I understand that all relevant and significant complications that are often seen or known about have been explained and understood, and that it is not possible for every single possible complication that could happen to be covered.I understand that I cannot be a smoker for at least 30 days prior to surgery, and smoking may result in cancellation of surgery with loss of deposit.

My Obligations and Responsibilities when having Bariatric surgery

Having bariatric surgery is not just about losing weight, but also committing to looking after your own health and well-being. There are a number of follow-up appointments with Dr Wong and his nurse that you will be expected to participate in as part of your follow-up pathway. These follow-up appointments have been explained to you previously, and a schedule of your appointments will be provided to you after your surgery. Because some of these appointments are arranged months or even a year in advance, it is expected that you make arrangements in your timetable to fit these in around work and other commitments.

There is risk of malnutrition or nutritional deficits after having bariatric surgery, and one of the most important aspects about having surgery is learning about the types of food you should be eating, the amounts and frequency, drinking enough fluids and taking vitamins and other supplements as directed.

You will need to take vitamins and other supplements for the rest of your entire life. You will also need to undergo blood tests to monitor your nutritional status for the rest of your entire life.

The pathway to have surgery requires multiple steps, which most people are not familiar with. It is our aim to provide you with as much information about everything, and we will communicate these things with you via email. It is your responsibility to read the emails and information that is provided to you, if you ever are wondering what to do next.

Acknowledgement of my obligations as a patient

I acknowledge and accept the responsibility and commitment that is required of me as a patient when undergoing bariatric surgery.I understand that there will be a number of appointments I need to attend or participate in.I understand the importance of dietitian care in learning about how I should be eating after surgery.I understand that I will need to take vitamins and other supplements for the rest of my life.I understand that I will need to get blood tests to monitor my nutrition for the rest of my life.I understand that all important information regarding my care pathway will be sent to me via email.

Clinical Photography and Video

It is standard practice for Dr Wong to capture images whilst performing surgery using the laparoscopic camera system. These photographs document key parts of the surgical procedure and form part of the clinical records for your surgery stored with the hospital and Dr Wong's practice.

Occasionally, de-identified clinical images are required for research study or teaching purposes and if one of the images captured from your surgery depicts a particular teaching point well, it may be used for this with your permission.

Dr Wong may also record parts of or the entire surgical procedure. This is so that if there are any complications that occur during your surgery, the footage can always be reviewed to try to identify a cause.

Consent for Clinical Photography and Video *

I consent to the use of imaging for medical record-keeping.I consent to the use of imaging for teaching purposes and to help explain the surgery to other patients.I consent to the use of imaging in medical publications, including medical journals, textbooks, and electronic publications.I consent to Dr Wong recording my surgery for potential future reference and teaching purposes.I DO NOT consent to any recordings being made during my surgery.

Blood Transfusions and Blood Products

A blood transfusion is not expected to be needed as part of surgery, however in an urgent situation it may be advised. Please state whether you consent to a blood transfusion being given if required.

You are encouraged to consent to blood transfusion unless you have a strong reason not to, and understand the consequences of refusing blood transfusion.

Blood transfusion is when you’re given blood, or components of blood such as red blood cells, plasma or cells called platelets, from someone else (a donor). It is a very safe procedure that can be lifesaving. It may be required if there is significant bleeding during or following the operation.

Compared to other everyday risks, the likelihood of getting an infection from blood transfusion is very low.

Donors and blood donations are screened for a number of infections which can be transmitted through blood, but it is not practical or even possible to screen donations for all infections, therefore, there will will always be a small risk associated with having blood transfusion.

Reactions can also occur despite best measures having been made to administer blood that is compatible with your blood type. Because of the strict processes and pathways that exist to match blood type, the check-points to eliminate error, serious blood incompatability reactions are very rare. Occasionally, mild reactions can occur such as fever.

Consent for Blood Products *

I consent to a blood transfusion or blood products if it is required.I DO NOT consent to a blood transfusion or blood products, and understand that declining this in the setting of serious bleeding could threaten my health and life.

Data Collection

Dr Wong submits data to the Bariatric Surgery Registry through Monash University. This data is de-identified, and enables important statistics on bariatric surgery to be kept in Australia to provide information about how many procedures are done per year and surgical outcomes and complications.

Dr Wong also maintains his own prospective database on every patient that he performs surgery on to enable him to track his case numbers and surgical outcomes for quality control, audit and potentially research study purposes.

Consent to Data Collection *

I consent to Dr Wong collecting and submitting data to the Bariatric Surgery Registry and I have been provided further information about this.I consent to Dr Wong collecting data to monitor my outcomes from surgery.I DO NOT consent to Dr Wong collecting any data for any purposes.

Third Parties present in the operating theatre

Industry product support specialists may be present in the operating theatre with Dr Wong, to provide support to Dr Wong and the theatre team for various pieces of equipment such as the laparoscopic camera, stack and screen, surgical devices and instruments or adjunctive agents used such as staple-line reinforcement, sutures or surgical glue.

Other surgical or medical personel may also be present in theatre to observe Dr Wong operating to learn about bariatric surgery. Such persons may include other surgeons, doctors, nurses, dietitians, medical or nursing students and paramedics. These persons are there purely to learn and observe, and will not have any role in performing or assisting the surgery.
