Louisiana A major advantage of LEEP is the removal of abnormal tissue while providing an adequate specimen for pathological study. Confirming complete removal of the lesion by observing specimen margins essentially eliminates the risk of missing microinvasive cancers. Treatment of even advanced lesions can be accomplished with the complete removal of the transformation zone or conization, with result comparable to knife conization. LEEP virtually eliminates this risk because it allows for histologic examination and complete removal of the tissue.
Cost is another major consideration.
LEEP also saves the hospital and anesthesia costs of conization in some cases. By improving diagnostic accuracy, LEEP may prevent the human and financial cost of missing microinvasive cancer.
