bronchial stump
Remaining portion of bronchus after surgical resection of lung tissue, prone to complications like dehiscence or infection.
Full Definition
A bronchial stump is the residual portion of a bronchus that remains after surgical lung resection, such as lobectomy, bilobectomy, or pneumonectomy. The bronchial stump requires careful surgical closure to prevent complications. Bronchial stump dehiscence is a serious postoperative complication where the closure fails, potentially leading to bronchopleural fistula, empyema, or respiratory failure. Risk factors for stump complications include poor tissue quality, infection, previous radiation therapy, and technical factors during surgery. Proper stump length, adequate blood supply, and tension-free closure are critical for healing.
Usage
Usage note: Critical term in post-surgical documentation; complications can be life-threatening.
