“…The most recent study addressing pulmonary findings in patients with chronic aspiration 18 included patients with and without aspiration diagnosed by VFSS who underwent chest CT. A comparison of the two groups revealed that the patients with aspiration had a higher frequency of changes such as atelectasis, centrilobular nodules, bronchiolectasis, consolidation, and ground-glass attenuation. Bronchial wall thickening and air trapping were the most prevalent findings in both groups; however, no significant differences were demonstrated.…”

The objective of this systematic review was to characterize chest CT findings in patients with dysphagia and pulmonary aspiration, identifying the characteristics and the methods used. The studies were selected from among those indexed in the Brazilian Virtual Library of Health, LILACS, Indice Bibliográfico Español de Ciencias de la Salud, Medline, Cochrane Library, SciELO, and PubMed databases. The search was carried out between June and July of 2016. Five articles were included and reviewed, all of them carried out in the last five years, published in English, and coming from different countries. The sample size in the selected studies ranged from 43 to 56 patients, with a predominance of adult and elderly subjects. The tomographic findings in patients with dysphagia-related aspiration were varied, including bronchiectasis, bronchial wall thickening, pulmonary nodules, consolidations, pleural effusion, ground-glass attenuation, atelectasis, septal thickening, fibrosis, and air trapping. Evidence suggests that chest CT findings in patients with aspiration are diverse. In this review, it was not possible to establish a consensus that could characterize a pattern of pulmonary aspiration in patients with dysphagia, further studies of the topic being needed.

Objective To evaluate gastrointestinal (GI) risk factors for bronchiectasis in children. We hypothesized that upper GI tract dysmotility would be associated with increased risk of bronchiectasis. Study design Subjects in this retrospective cohort study included those evaluated for persistent pulmonary symptoms in the Aerodigestive Center at Boston Children's Hospital who underwent chest computed tomography (CT) between 2002 and 2019. To determine gastrointestinal predictors of bronchiectasis, baseline characteristics, comorbidities, enteral tube status, medications received, gastroesophageal reflux burden, adequacy of swallow function, esophageal dysmotility, gastric dysmotility, and neutrophil count on bronchoalveolar lavage (BAL) were compared between patients with and without bronchiectasis. Proportions were compared with Fisher's exact test and binary logistic regression with stepwise selection was used for multivariate analysis. ROC analyses were utilized to compare BAL neutrophils and bronchiectasis. Results Of 192 subjects, 24% were found to have evidence of bronchiectasis on chest CT at age 7.9 ± 0.5 years. Enteral tubes (OR 5.77, 95% CI 2.25–14.83, p < 0.001) and increased BAL neutrophil count (OR 5.79, 95% CI 1.87–17.94, p = 0.002) were associated with increased risk while neurologic comorbidities were associated with decreased risk (OR 0.24, 95% CI 0.09–0.66, p = 0.006). Gastroesophageal reflux was not found to be a significant risk factor. Neutrophil counts >10% had 72% sensitivity and 60% specificity for identifying bronchiectasis. Conclusions Enteral tubes were associated with significantly increased risk of bronchiectasis but gastroesophageal reflux was not. Providers should consider obtaining chest CT to evaluate for bronchiectasis in children found to have unexplained elevated BAL neutrophil count.

Pulmonary computed tomography findings in patients with chronic aspiration detected by videofluoroscopic swallowing study

Abstract: CT findings of aspiration are very important, as pulmonary symptoms may be the first manifestation of this disorder. Knowledge of these findings is essential to enable the early diagnosis of aspiration disorders and prevent lung damage.
