How Aspire Assist System Helps You Lose Weight?

The Aspire assist system works differently than a gastric balloon and gastric sleeve or gastric bypass procedures.

As the name suggests, the “Aspire Assist System” aspirate your gastric contents after you take your meal. Simply, you eat your food and before the food is absorbed, the Aspire Assist System removes it from your body.

The amount of food you remove depends but generally 30% of the food that has been taken in is removed.

Removing food from the stomach after your meal also improves the symptoms of abdominal distension and bloating.

In the long run, it reduces stomach volume, the stomach gets adjusted to smaller meals and has some effects on the neuroendocrine axis that results in the suppression of satiety.

How is Aspire Assist Procedure Performed?

The Aspire Assist System is a much simpler procedure compared to a gastric sleeve or gastric bypass.

The patient is asked to take clear fluids 24 hours before the procedure. Under mild sedation, a tube is placed in the stomach that is attached to a suction system outside the stomach, similar to placing a PEG (percutaneous endoscopic gastrostomy) tube.

After placing the Aspire Assist System, the patient is trained as to how and when to aspirate gastric contents. The patient can go home 2 hours after the procedure is performed. A liquid diet is advised for 48 hours.

In addition, the Aspire Assist System can be removed at anytime the patient wants. It takes only half an hour for the physician to remove it with minimal complication rates.

How effective is Aspire Assist System for Weight Loss?

Aspire Assist System is one of the most effective and safest weight loss interventions. Its weight loss effects have been studied and compared with various weight loss interventions.

One of the studies that was published in 2018, compared the effectiveness of various weight loss procedures at different time intervals after the intervention is summarized here [Ref]

Aspire Assist System resulted in 25% or more weight loss in 58.8% of patients!

The mean weight loss with the Aspire Assist System is about 12.1%. However, some individuals respond very well to this intervention.

In about more than half the individuals, it is associated with 25% or more weight loss. This is greater than most medical weight loss interventions.

In absolute terms, it can result in a mean weight loss of about 16 kgs (36 pounds). However, this depends on the baseline weight and the dietary practices of the patient.

Long-term safety and efficacy of Aspire Assist System for Weight Loss:

Most weight loss interventions are effective for a short duration after which the patients start to regain their weight.

Long-term and persistent weight loss are key outcomes that are assessed when undergoing any weight loss intervention.

The long-term safety and efficacy of Aspire Assist System were evaluated in 201 individuals. The mean BMI of the study patients was 43.6 ± 7.2 -kg/m². Patients were followed for a period of four years.

The percentage of TWL (total weight loss) and EWL (excess weight loss) was calculated after each year for four years. The results of the study are tabulated below:

Table showing the percentage of weight lost each year:

Year

%TWL

% EWL

1 18.2 ± 9:4% 46-3± 26.3%
2 19.8 ± 11.3% 48.2 ± 28.2%
3 21.3 ± 9.6% 50.3 ± 26.2%
4 19-2 ± 13.1% 47.9 ± 36.2%

As shown in the table above, the weight loss observed each year was persistent.

The effect of Aspire Assist System on Metabolic Parameters:

Similarly, the effect of Aspire Assist System on metabolic diseases was also evaluated in the study. Except for the impact of Aspire Assist System on lipid profile, significant improvements were observed in diabetics and hypertensive patients.

The effects of Aspire Assist System on blood glucose and blood pressure are summarized in the table below:

Complications associated with Aspire Assist System.

The Aspire Assist System is a minimally invasive procedure and does not require any form of general anesthesia. That is why this system has minimum complications.

A few of the complications that can arise are:

  • Bleeding from gastrostomy site
  • Infection of gastrostomy site
  • Peritonitis ( Due to leakage of gastric contents intra-abdominally.
  • Benign pneumo-peritoneum. This is because of leakage of air while performing gastrostomy.
  • Gastric ulceration or erosion of stomach mucosa.
  • Buried bumper.

In Conclusion:

The Aspire Assist System is a minimally invasive effective weight loss intervention. It is associated with weight loss of about 1/4th of the baseline body weight.

It has got fewer side effects and can be reversed at any time the patient wishes to reverse it.
