Introduction: Obesity has been considered a
global epidemic and a serious public health problem closely related to other
diseases. Moreover, obese individuals have limitations in physical capacity and
pulmonary function. Weight loss induced by bariatric surgery appears to help
reverse this situation. However, questions about physical capacity and lung
function, and its relationship with body composition remain to be clarified.
Objective: To evaluate the physical capacity, body composition and lung
function in women undergoing bariatric surgery. Methods: Twenty five women who
underwent bariatric surgery between 6 and 24 months ago, and 10 non-obese women
were evaluated for exercise capacity by the six minutes walk test (6 MWT), body
composition by bio-electrical impedance analysis and lung function by spirometry
and measurement of maximal static respiratory pressures. Results: Subjects with
BMI <30 kg/m2 were found to have better physical performance, demonstrated by increased 6 MWT
distance, not differing from non-obese women. When compared with non-obese
women, there were no significant differences in body composition and lung function.
Higher BMI was correlated with shorter distances in 6 MWT. Conclusion: 6 to 24
months after surgery, when the weight loss of patients who underwent bariatric
surgery reaches levels considered non-obese, it provides improvement in physical
performance to a level similar to that of
Objective: To assess preoperative and postoperative spirometry values in patients undergoing lobectomy for sequelae of pulmonary tuberculosis. Method: A total of 20 patients (10 males) with history of treatment for tuberculosis and presenting with symptomatic sequelae (repeat infection or hemoptysis) who sought assistance at the chest surgery outpatient clinic between 11.09.07 and 04.02.10, were selected for the study. Only patients that met theeligibility criteria (symptomatic, submitted to tuberculosis treatment) were included in the study. The age of patients ranged from 15 to 56 years (mean: 35.75 years). The average treatment time for tuberculosis was 6 months and onset of symptoms occurred between 01 and 32 years after treatment. To assess the impact of surgery on the variables VC, FVC, FEV1, FEV1/FVC, FEF and PEF preoperative values were compared with postoperative values at 1st, 3rd, 6th and 12th month using the paired t test. The level of significance (α) applied for all tests was 5% where a value of p < 0.05 was considered significant. Results: 11 patients were treated because of recurrent infections and 9 because of haemoptysis. The most common lobectomy was right upper lobectomy (7 patients), followed by left upper lobectomy (6 patients), left lower lobectomy (6 patients), and right middle lobectomy (1 patient). There were no postoperative complications. There was no postoperative mortality. Conclusion: Based on the results of the present study, it can be concluded that, at the 12th postoperative month, spirometric parameters of patients with tuberculosis sequelae submitted to lobectomy had returned to preoperative levels.
