Recurrence of abnormal cervical cells : The risk tends to be lowest for cold knife conization (less than 2%) when compared to LEEP and cryosurgery (use of cold to destroy abnormal tissue). The rate of complete resection was 91% in the cold knife and 82% in the loop excision group, but histologic confirmation of residual CIN was obtained in only 2 (1.7%) women after cold knife conization and in 5 (4.2%) after loop excision. with the use of cold knife cone biopsy; however, LEEP is fast-er, cheaper and involves fewer complications [4]. To perform a cold-knife cone, use a #11 surgical blade to begin a circular incision starting at 12 o’clock on the face of the cervix, angling the tip of the blade toward the endocervical canal . Risk of recurrence lower with cold knife cone.   Preterm delivery: This is uncommon but can happen as a result of a cone biopsy. Objective. Allows assessmentof surgical margins Success rates high with both LEEP and cold knife cone. Success and complication rates were the same for the two methods. Treatment success of LEEP is reported as 98% 2), 96% 3), 96% 4), 95% 5), 91% 6) and 94% 7) in non-randomized studies. Perinatal risks in subsequent pregnancy higher with cold knife cone. In some cases, patients die within one year after the surgery. During a cone biopsy, your doctor will remove a small, cone-shaped part of your cervix. Cold Knife Cone Biopsy Success Rate. Use a uterine sound to mark a depth of 2 cm within the endo-cervical canal, typically the most cephalad margin of the cone. The cold knife cone biopsy success rate varies from 60% to 80%. Treatment Terminology However, the finding of a residual lesion following conization LEEP conization is a safe and cost effective procedure with a lower complication rate providing a significantly smaller specimen compared to cold knife conization. They will study it under a microscope to look for abnormal cells. To compare the histomorphologic and colposcopic results of cold knife conization and loop excision. If the patient survives, it may take up to two years before they are able to walk again. It usually takes about 4 to 6 weeks for your cervix to heal after this procedure. A small cone-shaped sample of tissue is removed from the cervix. Methods. This corresponds to a success rate of 92% after cold-knife and 95% after laser conization. This is call an endocervical curettage (ECC). CONCLUSIONS: Loop excision provides a sample that is adequate for histologic evaluation in most cases, results in the same success rate as cold knife conization, and allows optimal colposcopic surveillance in significantly more cases than cold knife excision. Wide conization with adequate evaluation of the surgical margins is considered sufficient to treat high-grade lesions. Loop excision cones were significantly shallower than those obtained by a cold knife. The procedure may be performed using a wire loop heated by electrical current (LEEP procedure), a scalpel (cold knife biopsy), or a laser beam. The cervical canal above the cone biopsy may also be scraped to remove cells for evaluation. Sixty-six women were randomly allocated to have the cone specimen removed by cold knife excision (n = 38) or loop excision (n = 28).Subjects eligible for inclusion were those who presented histologically verified grade 3 cervical intraepithelial neoplasia (CIN) or … LEEP is often preferred over a cold knife cone since it affords less blood loss, is performed more quickly, and can be done in an office setting 1). Abnormal cytology after conization was found in a total of 53 cases (12.5%), but a histologic confirmation of residual or recurrent CIN was made in only 27 women (6.4%).
