Introduction:

Liquid-filled intragastric balloons (IGBs) have emerged as a safe and effective option for managing overweight and obesity. However, there is limited information available regarding the implementation of liquid IGBs in individuals with low- and moderate-risk obesity.

Objective:

The objective of this study was to assess the implementation of liquid IGBs in low- and moderate-risk obese individuals in terms of weight loss, safety, and tolerance at four, six, and twelve months of treatment.

Materials and methods:

This prospective, descriptive observational study included 109 subjects with low- and moderate-risk obesity (body mass index [BMI] of 30-40 kg/m2), who underwent endoscopic implantation of liquid-filled IGBs. The variables analyzed included sex, age, initial and final weight, percentage of weight loss, and side effects.

Results:

Out of the 109 subjects, 75.22% were women. The average weight at baseline was 87.22 kg, with an average BMI of 31.59 kg/m2. Three different brands of IGBs were used: Orbera (n=103), Spatz3 (n=3), and Elipse (n=3). The average weight loss showed significant differences when analyzed by months and brands-Ellipse: four months (-4.6 kg), Spatz3: three months (-7 kg), Orbera: six months (15.2 kg), Orbera: twelve months (19.7 kg). The average reduction in BMI achieved was 27.71 kg/m2. The complication rate was 2.75%, with two cases (1.83%) attributed to intolerance (abdominal pain) and one case due to acute appendicitis (0.91%).

Conclusions:

The findings of this study indicate that liquid-filled IGBs are a safe and effective procedure for managing low- and moderate-risk obesity. A minimum duration of twelve months with an IGB implantation is considered optimal for individuals with low- and moderate-risk obesity.
