Spontaneous pneumomediastinum (SPM) is a rare disorder most often affecting young males which is generally self-limiting. Despite the benign prognosis with few complications and little morbidity, it frequently confuses clinicians in primary settings, who may have difficulty differentiating SPM from other serious organ ruptures, especially oesophageal rupture (the so-called Boerhaave syndrome), which may lead to mediastinitis and may be fatal, even with appropriate interventions. An overview of adult SPM is provided, reviewing 17 studies (414 patients), including our clinical experience, and finally an algorithm for diagnosis and management of SPM is proposed, based on the characteristics of SPM.
SPM is a self-limiting disease with mild inflammatory signs. For patients suspicious of SPM, shortened hospitalization for about 2 days with observation alone may be feasible, if their symptoms improve gradually. Otherwise, less invasive procedures, such as esophagram, should be performed immediately. Long-term follow-up is usually unnecessary. We propose a new algorithm for management of SPM based on clinical experience.
This prospective cohort study showed that GERD appears to be a predictive factor for hospitalization due to AECOPD and that severer GERD symptoms may be associated with more frequent AECOPD. Thus, further studies are warranted to evaluate the preventive effect of the therapy for GERD on AECOPD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
