We retrospectively analyzed 399 patients who underwent cervical conization from January 2011 to December 2015 at our hospital. After the procedure, the pathological diagnosis of 30 patients (9.6%), who were preoperatively diagnosed with CIN3, were upstaged. Patients with CIN3 should be treated by conization to obtain accurate diagnosis with surgical specimen. Four patients had recurrences after the operations. One of them had clear margin at first conization, but also had a recurrence of CIN3. One patient had a recurrence of IB1 squamous cell carcinoma which had CIN3 margins in the first operation. All patients with recurrent cancer were treated radically by reoperation. After conization, careful observation is recommended especially in first one year, because all recurrences in our cohort were diagnosed in one year after the first operation. 45 patients (11.3%) became pregnant after conization. Among them six cases (13.3%) were with preterm birth. When surgical is performed during lactation period, prevention of cervical stenosis after conization is recommended.
