Today, the problem of choosing a treatment method for spontaneous pneumothorax remains undoubtedly relevant. There are still no clear indications for the use of one or another treatment method. Currently, the main factor for the use of a particular treatment method is the criterion of time elapsed since the disease. The medical records of 368 patients were analyzed. Using inclusion and exclusion criteria, the database was reduced. The groups were compared based on the presence or absence of differences. Using dependency analysis, we excluded variables that were not related to the grouping of patients. The parameters for assessing the patient's condition are described, which, one way or another, influence group differences. Among these parameters, both physical and laboratory parameters were identified.
