Assessment of bariatric surgery results

Abstract

The objective was to evaluate the results of bariatric surgery in patients in the late postoperative period using the Bariatric Analysis and Reporting Outcome System (BAROS). This cross-sectional study was conducted from November 2011 to June 2012 at a hospital in the state of Ceará, Brazil. Data were collected from 92 patients using the BAROS protocol, which analyzes weight loss, improved comorbidities, complications, reoperations and Quality of Life (QoL). Data were analysed using the chi-squared test, Fischer's exact test and the Mann-Whitney test. There was a reduction in the Body Mass Index (47.2±6.8 kg/m2 in the pre-operatory and 31.3±5.0 kg/m2 after surgery, p<0.001). The comorbidity with the highest resolution was arterial hypertension (p<0.001), and QV improved in 94.6% of patients. The main complications were hair loss, incisional hernia and cholelithiasis. The surgery provided satisfactory weight loss and improvements in the comorbidities associated to a better QL. Use of the BAROS protocol allows nurses to plan interventions and maintain the good results.

Avaliação da qualidade de vida, perda de peso e comorbidades de pacientes submetidos à cirurgia bariátrica

“…The most common comorbidities were hypertension (42.4%), sleep apnea (24.1%) and diabetes (18.2%). These data were also found in other studies 17,18,20,23 . Barros et al 23 found an even higher prevalence of hypertension (50%) in the preoperative period.…”

“…When analyzing the relationship between bariatric surgery and its impact on weight loss, we noted, as others did, that this procedure has been shown to be quite effective 12,20,21,23 . The mean BMI before and after surgery was 48.10kg/ m 2 and 31.05kg/m 2 , respectively, which implies a significant reduction in cardiovascular mortality and in mortality from all causes associated with excessive weight 7,18 .…”

“…Understanding these motivational differences between men and women is of paramount importance, since they can be worked both in the pre-and postoperative period to try to approximate patients' expectations with the real results that can be achieved with bariatric surgery, including its positive aspects (weight loss, improvement/remission of comorbidities), as well as negative aspects (excess skin, scars, need to adhere to a new lifestyle and possible complications) 10,12,22,23 .…”

“…Our data corroborate those found in the literature on the subject. Barros et al 23 assessed quality of life using the Moorehead-Ardelt II quality of life questionnaire with 92 patients submitted to Roux-en-Y gastric bypass (Fobi-Capella) from the third postoperative month on, and reached the following conclusions: 75% of participants considered their QoL to be "much better", 19.6%, "better", and 5.4% rated the QoL as "unchanged." There was no rating as "bad" or "too bad."…”

“…For those individuals with BMI≥40kg/m 2 , as well as for those with BMI≥35kg/m 2 and who already have obesity-related diseases, bariatric surgery is the most effective therapeutic option for the loss of weight and reduction of complications resulting from overweight, thus offering a differentiated life and health perspective with an increase in QoL [6][7][8][9][10] . Thus, it is possible to notice that bariatric surgery works beyond weight loss, and its efficacy is also supported by the valorization of aspects that are important for patients, such as dietary reeducation, healthier lifestyle and psychological and social behaviors that improve quality of life and physical and mental health 9,10 .…”
