Gastric Sleeve Surgery is a weight loss procedure in which a large part of the stomach is surgically removed, reducing the stomach size by up to 85%, with the remaining portion of the stomach looking like a banana or a sleeve. Given the severely reduced stomach size, patients are unable to consume and digest as much food before quashing their hunger and feeling full - as a result, rapid weight loss can be achieved. This type of surgery is non-reversible and should only be considered as a final option.
A person is termed obese if their body mass index (BMI) is greater than 40 and their weight is 100 lbs / 50 kg more than their ideal weight. For these people, Bariatric Surgery is an available option. There are many associated risks concerned with Obesity that can lead to hypertension, infertility, diabetes, sleep apnea, and much more. When methods, such as dieting and exercising do not work, a Gastric Sleeve procedure can be the final solution, but not everyone is a good candidate and each individual should carefully consider the best options available to them, considering present condition, health history, cost, recovery time, success rate and pros and cons of the surgery. Alternatively, a Gastric Balloon may be preferred instead - see below for more information on this non-invasive procedure.
Surgery is performed under general anesthesia using a laparoscope, with several small incisions being made on the belly, a tube fitted with a camera (laparoscope) is then inserted through these incisions to give a clear picture of the insides. The surgeon will view these images, before beginning the process of surgically removing up to 85% of the stomach's volume using specialist surgical instruments. The remaining stomach pouch now resembles a dramatically reduced sleeve or banana. All the instruments are removed and the incisions are stitched and bandages applied to the wounds.
Gastric sleeve surgery is an inpatient procedure that lasts about one hour in the operation theatre. After this, you are moved to a recovery room where your vitals are monitored. A two to three days hospital stay is required after surgery and you are discharged when your condition is stable. You should stay in Porto Alegre for at least 7-8 days for follow up check-ups. During this period, you are kept under review and the stitches are removed after 5 to 7 days.
It will take two to three months to get back to normal meals and the amount of food you will eat is considerably decreased. You will likely suffer from a swollen and sore stomach for several days, with medicines being prescribed to help deal with the pain during this period. After two to four weeks, you can return to some normal activities, however, on average, six weeks of rest is required. As it is laparoscopic surgery, less time is required to recover and scars are small which fade away over time.
The following are some points to consider after leaving the hospital:
You can expect to lose 60% of your excess weight within 12 to 18 months post-surgery. The Gastric Sleeve is now the most popular form of Bariatric Surgery based on the extremely high success rates seen across the world. Patients can expect a huge decrease in weight, coupled with a vast improvement in health conditions and a reduction in such diseases as diabetes.
1. Gastric Band - Considered a reversible Bariatric Surgery option, a silicone device is fitted at the top portion of the stomach, cutting off the bottom section and creating a small stomach pouch above. The reduced stomach size now means the volume of food consumed is much smaller before the patient becomes full, thus resulting in rapid weight loss. Once the desired weight is achieved, the band can be surgically removed.
2. Gastric Bypass - The stomach is divided into two parts; a small upper pouch and a large lower ‘remnant’ pouch. The small intestine is rearranged accordingly, bypassing the large pouch and thus significantly reducing the volume of the stomach.
3. Gastric Balloon - This non-invasive procedure does not involve surgery and instead an inflatable balloon-like device is endoscopically placed into the stomach and inflated, thus reducing the capacity of the stomach. with the balloon occupying most of the stomachs volume, the patient becomes full much quicker, leading to rapid weight loss. Once the desired weight is achieved, the balloon is deflated and removed.
