Abstract

Cold coagulation of the cervix for cervical intraepithelial neoplasia (CIN), when compared with cervical excision, has previously demonstrated comparable cure rates and a reduction in the rate of spontaneous preterm birth. In the present report the healing pattern in the cervices of two women after cold coagulation is described. Both women underwent cold coagulation due to CIN3, which was found on pre‑treatment cervical punch biopsies. They were followed up after cold coagulation and at 7 and 18 months, respectively, they underwent cervical excision. The histopathological slides from the excised specimen were reviewed, which represents the healed cervix after cold coagulation. A clear boundary of collagenisation was noted in the superficial stroma, which appeared to stop at the junction with the healthy muscular stroma. The collagenised superficial stroma depth, which represents the area that was thermally ablated and has now healed, measured 1.6 and 1.5 mm for the two women, respectively, which is less compared with that typically removed by cervical excision. Observations from these two cases indicate that cold coagulation does not appear to disrupt the deep tissue architecture of the cervix and could therefore explain the reduced levels of adverse obstetric morbidity in patients who underwent cold coagulation ablative treatment of the cervix, which has been previously reported.
