Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to quantify the skin sensation of the anterior abdominal wall of the post-bariatric patients submitted to anchor-line abdominoplasty without flap undermining.

Additional purposes were: quantify topographically the abdominal skin sensation of the Normal weight, Morbid Obese and Former Morbid Obese after bariatric surgery (before and after the abdominoplasty - excess skin surgical removal without flap undermining -\> Anchor Line Abdominoplasty).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Abdominoplasty performed in post-bariatric patients presents more post-operative complications than in non post-bariatric patients. Surgical techniques that provokes less complications are required.

Anchor-line abdominoplasty is a technique published in the years 1950 as well the first bariatric proceedings. Abdominoplasty without flap undermining is feasible in pendular abdominal wall of the former morbidly obese women with scarred abdomen.

Classical abdominoplasty (with flap undermining) is known to impair significantly the skin sensation. Post-bariatric abdominoplasty without flap undermining keeps the skin sensation unaltered since the early post-operative period.

Now that the post-bariatric anchor-line abdominoplasty improves the abdominal wall contour by removing the exceeding, pendular and striated skin saving the perforant skin sensory nerves. Could this technique improve the skin sensation of the anterior abdominal wall of the post-bariatric patients?

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

STUDY

1. Female healthy volunteers (25 to 55 years old) with normal weight.
2. Morbid Obese women waiting for bariatric surgery.
3. Post-bariatric female patients, 25 to 55 years old, MORE than 12 months of weight stability, pendular abdominal wall, clinical conditions to anchor-line abdominoplasty without flap undermining. Skin Evaluation before the abdominoplasty.
4. Group 3, submitted to anchor-line abdominoplasty without flap undermining.

Group Type OTHER

Bariatric surgery (Roux-en-Y Gastric Bypass) + Post-bariatric abdominoplasty.

Intervention Type PROCEDURE

Surgical removal of the exceeding skin and adiposity of the abdominal wall by one midline vertical fuse and one supra-pubic horizontal fuse. Skin suture without flap undermining and with low tension.
