ANALYSIS OF COMPLICATIONS OF SURGICAL TREATMENT IN PATIENTS WITH LUNG TUMORS
The aim of the study was to identify factors that are associated with complications after surgery for lung cancer.
Materials and Methods. Retrospective analysis of the surgical treatment results in patients with lung cancer who were operated on in 2010-2014 at the department of thoracic surgery of the Lviv Oncological Regional Treatment and Diagnostic Center. The study included 461 patients. The data of each patient were divided into the following groups: general characteristics, tumor characteristics, treatment characteristics, and complications. The whole cohort of patients was analyzed and their separate subgroups were compared by age, type of complications, and type of surgery.
Results and Discussion. Elderly patients have three times higher levels of postoperative dyspnea and much higher levels of cardiac arrhythmias. Pulmonary complications are more common in men, after more aggressive surgeries with longer time of operative pulmonary ventilation; increase with age. This subgroup is also characterized by longer postoperative period and a higher in-hospital mortality rate. Postoperative complications such as dyspnea, fistula of the bronchial stump, and pleural empyema, higher levels of pleural punctures, and postoperative bed-day were more common in the group of patients who underwent pneumonectomy. A higher level of postoperative pneumonia and a longer drainage period were observed in the group of other operations. It is noteworthy that the level of dyspnea in elderly patients who underwent pneumonectomy is three times higher.
Conclusions. There are age-related features connected to the onset of postoperative complications in patients with lung tumors who have undergone surgery. Complications typical for the patients after different types of operations were found. It is established that the age of patients and the type of surgical treatment significantly change the palette of postoperative complications. An improved method for predicting complications is required.
