Abstract
Trapped lung syndrome is defined by the inability of the lung to expand and fill the thoracic cavity because of a restricting “peel.” This restriction may be secondary to inflammatory or fibrotic cortex or to a malignant visceral pleural tumor. This condition has a significant impact on the patient’s quality of life by causing dyspnea.
Video assisted thoracoscopic surgery (VATs) can take part in management of trapped lung syndrome more easily on the behalf of pleurectomy/ decortications and also provide more safe options with good results for malignant and terminal cases as VATs chemical pleurodesis.
Our study was carried out from marsh 2018 to august 2020, the study included 100 patients .Patients have been randomly incorporated into 2 equal groups
group A: patients who have been managed with conventional thoracotomy after 6 to 8 weeks of active drainage which has been the control group
group B: patients who have been managed early thoracoscopically (within first 2 weeks of presentation)
Regarding demographic data we found that the total mean age was 52.45 ± 13.62 years ranging from 19 to 80 years. Most of our patients were males (64%) and by using ANOVA test this was statistically insignificant.
In our study we found that 66% of patients were smokers, 13% were diabetics, 4% of patients gave history of ischemic heart disease, hypertension was present in 33% of the patient, 4% of patients gave history of pulmonary tuberculosis, 23% of patients were complaining of chronic obstructive pulmonary disease, 6% of the patients are on regular dialysis for end stage renal disease, 8 % of our patients reported history of previous thoracic surgery in8 % of total patients and 21% of patients gave history of different types of thoracic
