Bariatric surgery makes patients feel fuller faster. It is a treatment for obesity that is intended for patients who are at an advanced level of obesity. They must have a significant weight load to lose. Namely, a BMI over 40 or 35 with comorbidities. The preoperative follow-up for this type of operation is very thorough. Indeed, before being able to claim a bariatric surgery there is a whole process to follow. Appointment with the surgeon, a nutritionist and a psychologist. For several months, they assess whether or not a patient is fit for surgery.

There are four main operations in bariatric surgery:

  • Gastric Sleeve
  • Gastric Bypass
  • Gastric Botox
  • Gastric Balloon

Depending on the chosen operation, hospitalization varies between 1 and 7 days (gastric band placement is performed on an outpatient basis in more and more centers). The results obtained in the early stages and in the long term are very important. Ultimately, the loss of overweight, depending on the operation and the patient, varies between 40% and 80% of overweight. This weight loss helps reduce or eliminate the comorbidities associated with obesity.

Bariatric surgery: who is it for?
Bariatric surgery is a treatment for obesity that requires long and consistent follow-up. Whether before or after surgery. To qualify for this type of treatment, you must have a BMI between 35 and 40. This corresponds to moderate (or severe) and morbid obesity. This implies that the complication has at least one comorbidity that can be treated with surgery. Added to this are diet failures in an attempt to lose weight.

Adverse effects, depending on the operation chosen, may appear. They largely correspond to vomiting and nutritional deficiencies.


Gastric Sleeve

Gastric sleeve is a surgical procedure that induces weight loss by restricting food intake. With this procedure, which is usually performed laparoscopically, the surgeon removes approximately 75 percent of the stomach. This results in the stomach taking on the shape of a tube or "sleeve" which holds much less food.

Sleeve gastrectomy is considered one of the safest plastic surgery procedures. Its duration does not exceed a minute only. But it needs criteria for its success:

  • High-Quality Hospital
  • A skilled surgeon
  • Full commitment to the instructions after the operation in the first year in particular
  • And your life will change forever...

Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 15% of its original size, by surgical removal of a large portion of the stomach along the greater curvature. The result is a sleeve or tube-like structure. The procedure permanently reduces the size of the stomach, although there could be some dilatation of the stomach later on in life. The procedure is generally performed laparoscopically and is irreversible.


Sleeve gastrectomy was originally performed as a modification to another bariatric procedure, the duodenal switch, and then later as the first part of a two-stage gastric bypass operation on extremely obese patients for whom the risk of performing gastric bypass surgery was deemed too large. The initial weight loss in these patients was so successful it began to be investigated as a stand-alone procedure.

Sleeve gastrectomy is the most commonly performed bariatric surgery worldwide. In many cases, sleeve gastrectomy is as effective as gastric bypass surgery, including improvements in glucose homeostasis before substantial weight loss has occurred. This weight-loss independent benefit is related to the decrease in gastric volume, changes in gut peptides, and expression of genes involved in glucose absorption.

The procedure involves a longitudinal resection of the stomach starting from the antrum at the point 5–6 cm from the pylorus and finishing at the fundus close to the cardia. The remaining gastric sleeve is calibrated with a bougie. Most surgeons prefer to use a bougie between 36 and 40 Fr with the procedure and the ideal approximate remaining size of the stomach after the procedure is about 150 mL.

Use in children and adolescents is endorsed by the International Federation for the Surgery of Obesity and Metabolic Disorders and the American Society for Metabolic and Bariatric Surgery

Gastric Balloon

Gastric balloon is the second most common stomach operation after sleeve gastrectomy thanks to its very few side effects and good results without cutting the stomach.

A gastric balloon, also known as an intragastrical balloon (IGB) or a stomach balloon, is an inflatable medical device that is temporarily placed into the stomach to help reduce weight. It is designed to help provide weight loss when diet and exercise have failed and surgery is not wanted or not recommended for the patient.

Currently, there are three FDA-approved balloons in the USA. These approved devices are placed via the esophagus using endoscopy. This can be done in an outpatient setting under sedation. One further balloon, Allurion’s Ellipse, has European CE approval and does not require endoscopy for placement or removal.

It is a non-surgical procedure performed with local anesthesia that is performed to lose weight for those who suffer from excess weight by an amount not exceeding 25 kg. The idea of ​​this process is based on reducing the stomach area, to reduce the amount of food consumed until the feeling of satiety, which works to lose weight. Months 


Once in place, the balloon is filled with saline and remains as a free-floating object in the stomach cavity, too big to pass through the pylorus. In addition to saline, the balloon that is made from silicone may contain some radio-opaque material as a radiographic marker and a dye such as methylene blue to alert the patient if the balloon leaks. Studies have suggested that fluid is superior to air for distending gastric balloons. Inflated balloons reduce the operative volume capacity of the stomach. While the typical gastric volume is about 900 ml, an inflated balloon may take up most of the space, about 700 (+/-100) ml.

Safety and side effects

Gastric balloons are generally considered to be safe and effective in the short. Existing clinical data shows an acceptable safety profile. One of the largest intragastrical balloon studies ever performed, which included 1770 patients, demonstrated an excellent safety profile.

There can be procedure-related side effects due to endoscopy and anesthesia on balloons that require medical intervention for placement or removal. On very rare occasions, the endoscopic placement of a balloon has led to death.

Several studies have demonstrated that the data on both the efficacy and safety for the non-endoscopic Allurion Elipse gastric balloon compares favorably with balloons that require endoscopy. It showed an acceptable safety profile with 0.2% of serious adverse events, which is comparable to the Orbera balloon, which requires endoscopy

Post-placement side effects of gastric balloons are common and may include nausea, vomiting, reflux, and stomach cramps.

Other side effects include indigestion, bloating, flatulence and diarrhea.
