<qa>  What is the average length of stay required when complications occur?The use of computed tomography CT screening has allowed for early detection of lung cancers as small as 5mm in diameter. Early stage cancers are highly curable with a reported survival of greater than 90 over 5 years after surgical resection. Before a patient can have surgery, a biopsy must be performed. One common method is a transthoracic needle biopsy TTNB. In this procedure, a CT-image is used to locate the area for biopsy. Once identified, the radiologist applies a local anesthetic and inserts an aspiration needle through the ribs, and into the lung tissue. The sampled lung tissue is then sent to pathology. Although this procedure has a diagnostic yield ranging between 70 and 85, it is associated with serious complications such as pneumothorax, hemoptysis, infection, hemothorax, air embolism and there is about a 20 range 9-54 incidence of pneumothorax, or air leak from the lung, requiring chest tube drainage. Additionally, about 5-15 of cases experience hemoptysis, or coughing blood, although significant life-threatening hemoptysis is only present in less than 1 of patients. When these complications occur, hospitalization as inpatients is required, with an average length of stay of 1-3 days.
