“…This reduction does not represent an actual pulmonary restriction, but rather a restrictive behavior which usually tends to improve after weight loss as shown by the mean postoperative value of 3.07 l compared to the preoperative value of value of 2.60 l. Other studies have also reported a similar improvement of FRC over a six month period after the Fobi-Capella operation 6,9,10 .…”

Purpose: To investigate the body weight, pulmonary function and quality of life of twenty patients with morbid obesity six months after the Fobi-Capella operation. Methods: Patients were evaluated before and six months after surgery. The patients were mainly female (75%), the average age was 40.5 ± 10.27 years; average weight 110.11 kg ± 21.77 and average body mass index (BMI) 39.93 ± 7.13 kg/m 2 in the postoperative evaluation. Pulmonary function was assessed by spirometry using a Pulmonet/Godart NV Bilt Vetr Hotland spirometer and quality of life was assessed by applying the Moorehead-Ardelt questionnaire. The pre-and postoperative spirometry values were compared by the paired Student t test and the correlation between weight loss and pulmonary function was determined by linear regression, with the level of significance set at p < 0.05. Results: The spirometry variables Respiratory Frequency (RF), Expiratory Reserve Volume (ERV) and Functional Residual Capacity (FRC) differed significantly between the pre-and postoperative periods, whereas Residual Volume (RV), Vital Capacity (VC), Total Lung Capacity (TLC), FEF (Forced Expiratory Flow between 25 and 75% FVC) and FEV1/FVC% (Forced Expiratory Volume in the 1 st second/ Forced Vital Capacity ratio) did not differ between periods. Only one patient reported worsening of quality of life. There was a positive correlation between weight loss and ERV (p=0.0117, r=0.5514), but no correlations were observed for the other variables. Conclusions: There was a significant weight loss and an improvement of pulmonary function as seen by respiratory frequency, reduction and increased expiratory reserve volume and functional residual capacity. The quality of life of the patients also improved after the Fobi-Capella operation. Key words: Obesity, Morbid. Respiratory Function Tests. Quality of Life. Bariatric Surgery. RESUMOObjetivo: Investigar a evolução do peso corpóreo, da função pulmonar e da qualidade de vida de 20 pacientes obesos mórbidos seis meses após operação de Fobi-Capella. Métodos: Os pacientes foram avaliados antes e seis meses após a cirurgia e o sexo feminino predominou em 75%, com média de idade de 40,5 anos ± 10, 27, média de peso de 110,11 kg ± 21,77 e IMC de 39,93 kg/m 2 ± 7,13. Para a avaliação da função pulmonar foi realizada espirometria por meio do espirômetro Pulmonet Godart NV Bilt Vetr Holland, e para a qualidade de vida foi aplicado o questionário de Moorehead-Ardelt. As comparações entre os valores espirométricos do pré e do pós-operatório foram realizadas pelo teste t de Student para amostras pareadas, e para a correlação entre a perda de peso e função pulmonar utilizou-se análise de regressão linear simples, adotando-se p < 0,05 para todos os resultados. Resultados: As variáveis espirométricas Freqüência Respiratória (FR), Volume de Reserva Expiratório (VRE) e Capacidade Residual Funcional (CRF) apresentaram, aos seis meses após a operação, diferença estatisticamente significativa com os valores pré-operatórios, porém, não houve diferença ...

“…Excess weight may cause impaired pulmonary function, especially in morbid obesity [6][7][8] . Thus, it is interesting to study pulmonary function by spirometry during the preoperative period in order to investigate the possibility of restrictive or obstructive pulmonary disorder.…”

“…11,17,18 As total and abdominal fat increase, vital capacity (VC) and forced expiratory volume (FEV 1 ) are proportionally compromised. Furthermore, massive adipose accumulations in the thorax and abdomen interfere with pulmonary volumes and gas exchange, especially in the supine position.…”

“…Some studies suggest that most deranged parameters improve in the late postoperative period after a more normal body composition has been achieved, even without deliberate exercise. 17,18 Although few specific references to bariatric candidates could be identified in the literature, it is reasonable to propose that more encouraging outcomes would be elicited if progressive physical conditioning were offered to this population jointly with surgical therapy.

Pulmonary function and aerobic capacity in asymptomatic bariatric candidates with very severe morbid obesity

PURPOSE:Aerobic capacity and respiratory function may be compromised in obesity, but few studies have been done in highly obese bariatric candidates. In a prospective study, these variables were documented in the preoperative period, aiming to define possible physiologic limitations in a apparently healthy and asymptomatic population.METHOD: Forty-six consecutively enrolled adults (age 39.6 ± 8.4 years, 87.0% females, body mass index /BMI 49.6 ± 6.3 kg/m 2 ) were analyzed. Ventilatory variables were investigated by automated spirometry, aerobic capacity was estimated by a modified Bruce test in an ergometric treadmill, and body composition was determined by bioimpedance analysis.RESULTS: Total fat was greatly increased (46.4 ± 4.6% of body weight) and body water reduced (47.3 ± 4.6 % body weight), as expected for such obese group. Spirometric findings including forced vital capacity of 3.3 ± 0.8 L and forced expiratory volume-1 second of 2.6 ± 0.6 L were usually acceptable for age and gender, but mild restrictive pulmonary insufficiency was diagnosed in 20.9%. Aerobic capacity was more markedly diminished, as reflected by very modest maximal time (4.5 ± 1.1 min) and distance (322 ±142 m) along with proportionally elevated maximal oxygen consumption (23.4 ± 9.5 mL/kg/min) achieved by these subjects during test exercise.CONCLUSIONS: 1) Cardiopulmonary evaluation was feasible and well-tolerated in this severely obese population; 2) Mean spirometric variables were not diminished in this study, but part of the population displayed mild restrictive changes; 3) Exercise tolerance was very negatively influenced by obesity, resulting in reduced endurance and excessive metabolic cost for the treadmill run; 4) More attention to fitness and aerobic capacity is recommended for seriously obese bariatric candidates;

“…A implantação de centros de reabilitação pode ser apontada como uma solução no tratamento de indivíduos com sobrepeso e obesidade, permitindo, assim, realizar as secundárias sobre as enfermidades comumente descritas na literatura (5). Além dos distúrbios sobre o sistema cardiovascular, o quadro de obesidade contribui, também, para alterações no fluxo ventilatório, ocasionando, em geral, distúrbios restritivos, o que em consonância a outros fatores determinantes favorece a morbidade e mortalidade (5,8). As alterações ventilatórias acarretam redução do volume de reserva expiratório (VRE), diminuição da complacência pulmonar e torácica levando a 0,001), pressão inspiratória máxima com − 69,75 ± 21,37 cmH₂O (p = 0,045) e pressão expiratória máxima com 74,50 ± 28,23 cmH₂O (p = 0,000) e na percepção da qualidade de vida em seu estado geral de saúde 76,5 ± 14,04 (p = 0,033), aspectos sociais 83,1 ± 18,71 (p = 0,031), aspectos emocionais 88,4 ± 19,52 (p = 0,042) e na saúde mental 83,4 ± 14,81 (p = 0,049).…”
