Objective: To determine the characteristics of pulmonary function tests in patients with bronchiectasis secondary to pulmonary tuberculosis in Dos de Mayo National Hospital in Lima, Peru, during 2015 to 2016. Material and Methods: This is a quantitative observational, descriptive, and retrospective study. Data from clinical records of patients diagnosed with bronchiectasis secondary to pulmonary tuberculosis and other associated variables was collected. Results: Seventy-six clinical records with available data from pulmonary function tests were reviewed. With respect to spirometry we found that 40.8% had an obstructive pattern, and 22.3% had a restrictive pattern. When plethysmography was performed, it was determined that 61.8% had criteria for air trapping, because of having a >120% residual volume, and 9.2% had criteria for defining pulmonary hyperinflation due to a >120% total lung capacity. Also, statistically significant changes were found in plethysmography values after using bronchodilators. Conclusions: The most frequent pattern in these patients was obstructive, with air trapping and no pulmonary hyperinflation.
