Study Details

Study Description

Brief Summary

The purpose of the study is to evaluate the therapeutic effect of High intensity focused ultrasound in treatment of abdominal skin laxity post sleeve gastrectomy.

Condition or Disease Intervention/Treatment Phase
  • Device: High intensity focused ultrasound
  • Other: topical firming creams
N/A

Detailed Description

Lax skin is a common consequence of bariatric weight loss, and it may require one or more plastic interventions.

This study carried out to investigate the effectiveness of High-intensity focused ultrasound (HIFU) in treatment of abdominal skin laxity post sleeve gastrectomy.

Arms and Interventions

Arm Intervention/Treatment
Experimental: high intensity focused ultrasound group

This group includes 43 patients who have abdominal skin laxity post sleeve gastrectomy and who will receive high intensity focused ultrasound. patients will receive one session; time of session is 40 minutes.

Device: High intensity focused ultrasound
Parameters: Transducer frequency 7-2-mhz 1.5-9.0-mm focal depth. The pulse duration for each individual exposure ranged from 25 to 40 milliseconds. Energy per ultrasound pulse ranged from 1.0 to 1.5 J

Active Comparator: medical topical firming creams group

This group includes 43 patients who have abdominal skin laxity post sleeve gastrectomy and who will receive medical topical firming creams.

Other: topical firming creams
medical topical firming creams

Outcome Measures

Primary Outcome Measures

  1. Assessment othe change in skin laxity [at baseline and after 4 weeks of intervention]

    By Investigator Global Aesthetic Improvement Scale (IGAIS). The investigator will take clinical photographs using consistent patient positioning, camera settings (Canon EOS 600D, high-resolution setting, 5760 × 3840 pixels, Canon Inc., Tokyo, Japan), and room lighting. Baseline and post-treatment photographs will randomly displayed, and evaluated by Investigator Global Aesthetic Improvement Scale (IGAIS) scores will be determined using side-by-side comparisons of pretreatment and post 4 weeks of treatment. The scale ranges from 0 to 3 as 0 = No change, 1 = Mild improvement, 2 = Moderate improvement, 3 = Significant improvement.

  2. Assessment the change in abdominal skin laxity [at baseline and after 4 weeks of intervention]

    Assessment of abdominal skin laxity by the modified tissue tonometer : Mark multiple points to be measured. Include an equivalent normal skin point(s). Apply the MTT baseplate directly to the tissue through the holes in the template. Hold MTT vertically, with bubble of spirit level centered. Ensure no extra downward pressure is applied while resting the device on the tissue. Record the depression of the plunger in millimeters after 6 seconds. The patient must be able to remain immobile when the MTT is in contact. Repeat each point three times with at least 2 minutes' "rest" between attempts. Recalibrate the device to zero on a solid surface between each set of measures. To determine longitudinal change in measures, comparison of averaged score for individual points is appropriate and/or analysis of the change of individual sagging points difference from normal skin control point(s).
