A prospective study of the treatment of cervical intraepithelial neoplasia by loop electrosurgical excision procedure (LEEP) in Hong Kong population.

From May to December 1990, 72 patients suffering from cervical intraepithelial neoplasia confirmed with guided biopsy were treated with loop electrosurgical excision procedure (LEEP) as outpatients under local anaesthesia. Overall success rate of a single treatment at 6 weeks follow-up was 88.9%. All the specimens obtained from the procedure were of good quality for histological examination. The overall significant complication rate of the procedure was 4.2% during treatment and 8.4% after treatment. The results suggested that LEEP is an effective and safe outpatient treatment for CIN lesions. It is easy to use and readily acceptable to patients. It also has the advantage of providing histological confirmation and more economical than the use of laser.
