Abstract

Introduction

Body contour surgery (BCS) is a combination of soft tissue resections that have proven to be an effective treatment for the aesthetic and functional problems related to massive weight loss (MWL). There are no studies analyzing the metabolic effect of large volume adipose tissue flap resection in patients with MWL after bariatric surgery.

Methods

This study was a retrospective review of adults who underwent BCS after gastric bypass. Preoperative clinical and laboratory data were compared with 1- and 2-year postoperative follow-up.

Results

A total of 62 patients with a mean age of 41 years were analyzed. Seventy-nine percent of them were women. Most procedures included abdominal flap resection alone or in combination with other areas. Mean resected tissue weight was 6.2 kg. We found that weight and body mass index (BMI) were lower 1 year after BCS (P < 0.05), but this was not maintained after 2 years. There were no differences for systolic or diastolic blood pressure, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, or fasting glucose after 1 and 2 years of the BCS. A subgroup analysis showed that the transient weight and BMI improvement was only apparent 1 year after BCS in those patients with flap resections more than 8 kg.

Conclusions

There are no differences in blood pressure, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, or fasting glucose 1 and 2 years after BCS in patients who experienced MWL after gastric bypass. Although weight and BMI were transiently lower in those patients with tissue flap resections more than 8 kg, this effect disappeared after 2 years.
