Post-bariatric body contouring surgery: analysis of complications in 180 consecutive patients

Access to reconstructive plastic surgery for patients undergoing bariatric surgery in the Unified Health System (SUS)

INTRODUCTION

obesity is one of the most common diseases worldwide, and the most effective treatment to it is the bariatric surgery. One of the negative impacts of this procedure is the body dysmorphia caused by overhanging skin. In Brazil, the national health system - Sistema Único de Sáude (SUS) - provide body contouring surgery to treat post-bariatric patients, since 2007. This article aims to describe the Brazilian public health approach to post bariatric patients and perform an analyze in the Brazilian health care database.

METHODS

in Brazilian Health System database, a search for the post-bariatric procedures performed between 2007 to 2021 was done. The variables analyzed were geographic location, year, mean days of hospitalization, death, and mortality rate. Also, we evaluated the number of bariatric procedures done in the same period. Statistical analysis was performed using the Student-t and the chi-square tests and p-value <0.5 was considered significant.

RESULTS

a total of 12,717 plastic surgery procedures in post bariatric patients were done, with a national prevalence of 13.8%. Dermolipectomy was the most performed procedure, with 6,719. The years of 2020 and 2021 suffered a decreased of 64.3% and 70.9% in the number of surgeries (p<0,001). Bariatric Procedures had a high rate and a higher percentage of growth comparing to post bariatric surgery (p<0,001), totalizing 93,589 surgeries.

CONCLUSIONS

Brazil had a significant number of body contouring surgery, however with a low prevalence. Dermoliepctomy was the most common procedure performed. We could notice a significant impact of COVID pandemic in those procedures .

Status of Body Contouring Following Metabolic Bariatric Surgery in a Tertiary Hospital of Greece-Still a Long Way to Go

Obesity is a disease rather than a state, and metabolic bariatric surgery (MBS) is its most effective treatment. Body contouring surgery (BCS) is an integral part of the continuum of care following MBS, provided that the body mass index (BMI) has stabilized for an adequate period. This study is an attempt to capture the current status of BCS following MBS in Greece, based on data from one of the country's highest-volume hospitals. We recruited patients from the Bariatric and Plastic-Reconstructive Surgery registries who had undergone both MBS and BCS and invited them to answer a structured questionnaire with components on demographics, safety and effectiveness of previous operations, quality of life (QoL), body image, social activity, sexual activity, and doctor-patient communication. Twenty-four patients participated in the survey (response rate 88.1%). The mean BMI pre-MBS was 43.8 kg/m² and that pre-BCS was 28.6 kg/m². Based on the Bariatric sub-cohort, only 2.5% of post-bariatric patients underwent BCS. The mean interval between MBS and BCS was 2.9 years. The distribution of patients by MBS was as follows: sleeve gastrectomy 8 (33.3%), gastric band 7 (29.2%), gastric bypass 5 (20.8%), and gastric plication 2 (8.3%). The distribution of patients by BCS was as follows: abdominoplasty 23 (94.7%), breast contouring 8 (33.3%), thigh contouring 3 (12.5%), and arm contouring 5 (20.8%). Most positive components (70.6%) regarding QoL were appraised by >80% of the participants, indicating overall satisfaction after BCS. Conversely, only 12.5% of negative components were endorsed by >20% of patients. In conclusion, BCS has a low prevalence after MBS, although it is related to an improved quality of life and body image.

IS THE WAIST/HEIGHT RATIO A BETTER PARAMETER THAN BMI IN DETERMINING THE CARDIOMETABOLIC RISK PROFILE OF OBESE PEOPLE?

Background:

The increased prevalence of obesity has led to a significant increase in the occurrence of metabolic syndrome, a recognized risk factor for increased morbidity and mortality from cardiovascular diseases. Hyperglycemia or type 2 diabetes mellitus, dyslipidemia and arterial hypertension are its main components. Since 2015, international guidelines have recognized the benefits of bariatric surgery in each isolated factor of this syndrome.

Aim:

To evaluate the impact of Roux-en-Y gastric bypass in this syndrome comparing pre- and postoperative periods with laboratory analysis and to compare waist/height ratio and BMI in relation to the determination of the cardiometabolic risk profile.

Methods:

A retrospective study was carried out, selecting 80 patients undergoing Roux-en-Y gastric bypass. Total cholesterol, HDL, LDL, triglycerides, fasting glucose, glycated hemoglobin, insulin, body mass index (BMI), vitamin D, vitamin B12, waist circumference and waist/height ratio in three periods were analyzed: the preoperative period from 1 to 6 months, postoperative from 1 to 6 months and postoperative from 1 to 2 years.

Results:

There was an improvement in all parameters of the clinical analyses. The preoperative BMI had a mean value of 39.8, in the preoperative period from 1 to 6 months, the values ​​dropped to 33.2 and in the postoperative period of 1 year, the mean was 26. The perimeter mean values ​​of 118.5 preoperatively, 105.2 postoperatively from 1 to 6 months and 90.3 postoperatively from 1 to 2 years. Waist/height ratio was 0.73, 0.65 and 0.56 in pre, post 1 to 6 months and 1 to 2 years respectively.

Conclusion:

Roux-en-Y gastric bypass improves metabolic syndrome and waist-to-height ratio is superior to BMI in the assessment of the cardiometabolic risk profile.
