Real and predicted lung function after anatomical lung resections (review of literature)

The function of the respiratory parenchyma remaining after lung resection is one of the determining factors of the immediate result of the operation and the postoperative quality of life. A number of studies have been conducted to objectify the preoperative prognosis of the functional safety limit of thoracic interventions using a variety of methods and formulas. Unfortunately, until now, there is no convincing data on the correctness of at least one of the proposed methods for predicting respiratory function. The process of rehabilitation of postoperative ventilation function in the lungs is affected not only by the volume of parenchymal resection, but also by the area of resection, the method and trauma of access, the severity of emphysema, intraoperative trauma of mediastinal structures, postoperative progression of pulmonary fibrosis, etc., and video assisted surgery and segmental resections do not provide an obvious functional advantage in the long term after operations. During the first year after anatomical resection of the lung, functional indicators usually improve. Reasons (or reason) of such improvements are not always clear and may be associated with compensatory growth of the pulmonary parenchyma in a number of patients.
