What Happens in the Hospital?

Where do I go?

All our surgeries are performed at the Centre Métropolitain de Chirurgie located at 999 Salaberry W. Montreal, Quebec, H3L 1L2. It is imperative that you follow the instructions given to you precisely especially the arrival time at the hospital.

You should not eat or drink anything after midnight the night before your operation.

What do I bring with me?

You will be given detailed instructions by our office. In general, bring supplies from home for a 2-day hospital stay.

If you use special equipment for sleep apnea, you should bring your machine to the hospital.

Bring all your medications with you to the hospital.

Also, bring the Weight Loss Surgery Information folder given to you at the office consult.

Admission to Hospital

You will be admitted to the hospital and the staff will verify all your case history forms and medications, secure your belongings and ask you to sign the informed consent form appropriate to your operation. You will then be brought to the operating room and prepared for surgery.

After the Operation

Your operation will last from 40-90 minutes depending on your BMI, the type of surgery chosen and previous surgeries if any. After the operation you will be brought to the recovery room, where you will slowly wake up from the anaesthetic. The nursing team in the recovery room will be checking you closely during this period.

From the recovery room, you will be transferred to your room where you will be given oxygen and your blood oxygen level will be continuously monitored using an oxygen saturation monitoring device. This is just a precaution because up to 40% of morbidly obese patients have Obesity Hypoventilation Syndrome or Sleep apnoea. This, together with the anaesthetic can result in low oxygen levels in the blood which can be harmful.

Pain Control

With the laparoscopic approach to weight loss surgery used in all our patients, pain and discomfort are minimized. Immediately after the operation you will experience some abdominal discomfort from the carbon dioxide gas used to blow up your belly for the surgery. Most of this gas is removed at the end of the operation. The remaining gas will be absorbed into your blood and removed by breathing it out your lungs over the next 36 hours. Even though your nurse may give you very strong pain medicine, this discomfort will be a bit unpleasant the nigh of your surgery.

The only pain medication you will need when you go home is acetominophen (Tylenol). If you have pain not relieved by tylenol (you can even use the double strength tablets or elixir) please cal us.

Dressings and Tubes

The dressing covering the incision sites will be removed the day after the operation. You can have a shower that day and as many as you want afterwards. The cuts are closed with surgical staples that will be removed 2 weeks after the surgery. We ask that you leave the cuts uncovered and open to the air. Do not put any creams or ointments over the cuts. Bacteria cannot grow in a dry environment.

Our patients have no tubes coming out of their noses or their bellies. In special circumstances (say difficult anatomy we find in less than 0.5% of cases), a small tube may be placed in the belly and come out next to a cut with a small bulb attached to it. This is a precaution to catch any leakage that may occur from your new stomach stitches. The tube will remain there for the first 3-4 days to help drain any infection that may occur after the surgery. The nurse will clean the site daily and empty the drainage regularly. The tube may be removed before you go home or in the office at 2 weeks.


After surgery you will be expected to participate actively in your care. You need to take an active role in preventing complications and promoting the natural healing that will occur. As soon as you are awake we will encourage you to do breathing exercises at least every hour. Deep breathing and coughing is necessary to clear the lungs of the mucus that develops after you have been under an anaesthetic.

The day of your surgery, the nurse will help you get up and sit in a chair. You will be assisted when walking more frequently and for longer distances in the following days. Getting out of bed is important to help your circulation, as well as to help expand your lungs and get rid of secretions. When you are getting up for the first time, it is normal to feel dizzy and weak as well as to feel some pain. These symptoms will be lessened by moving slowly; they will diminish with time.

What will I eat?

A liquid diet will be provided.

When do I go home?

Laparoscopic gastric bypass patients go home 2 days after their surgery. Laparoscopic sleeve gastrectomy patients can usually go home the day after their surgery.

Your surgeon will discharge you from the hospital. He will answer any last minute questions and review your diet plan one more time. He will give you an envelope with follow-up information and a prescription for your vitamins and supplements. You will start your vitamins about 10 days after your surgery.

We ask our out of town patients to stay in the Montreal for a few days after they leave the hospital before they fly home.
