ENDOSCOPIC REMOVAL OF A RARE LARGE OCCLUSIVE TRACHEAL TUMOR WITH LIMITED TECHNICAL CAPABILITIES

Relevance: Tracheal tumors often do not cause symptoms until they grow to a size that causes significant airway obstruction, which is the reason for the delay in diagnosis. Diagnosis may also be delayed due to non-specific symptoms, such as cough, wheezing, and shortness of breath, which can occur in other conditions such as asthma and chronic obstructive pulmonary disease. The symptoms that appear may vary depending on the type and location of the tumor. The literature does not sufficiently cover the experience of treating large occlusive tracheal tumors using segmental tracheal resection, endoscopic treatment, or radiation therapy. In scientific literature, the number of published studies with long-term results of endoscopic treatment or radiation therapy of such occlusive tracheal tumors is limited, and this problem requires further study. This article describes the first recorded case of endoscopic removal of a large occlusive tracheal tumor. The study aimed to show the possibility and effectiveness of endoscopic treatment using a minimum set of endoscopic equipment. Methods: This article presents a case of successful minimally invasive endoscopic treatment of a large occlusive tracheal tumor. Results: A large obstructing tumor of the trachea that almost completely blocked the trachea lumen was removed in one block by endoscopic loop resection. Conclusion: The presented clinical case describes the experience of successful endoscopic removal of a rare occlusive tumor of the trachea, which caused shortness of breath at rest and during exercise. For the first time in Kazakhstan, based on the National Scientific Cancer Center, we performed a unique minimally invasive operation to remove a tracheal tumor, while other clinics offered thoracotomic surgical resection methods
