Sometimes pathology results after LEEP or cold knife conization for various degrees of CIN report positive margins, which makes the majority of CIN patients extremely nervous. In fact, the results of our case summary show that nearly 70% of the so-called positive cut margins after LEEP or cold knife conization are not clean, that is, the cut margins shown in our pathology results are the edges of our excised tissues, and such edges are not equal to the cut margins of the remaining cervical tissues after our conization. Presumably, the probability that the margin of the excised tissue is positive and the margin of the remaining cervical tissue after conization is also positive is only about 30%. This reminds us that positive margins after CIN conization (or LEEP) do not always need to be treated aggressively. So what should be done for a positive margin after conization (LEEP)? If the pathology after conization (LEEP) shows positive margins, if the positive pathology is CIN1, which is a low-grade lesion, it can be monitored regularly. If the pathology after conization (LEEP) shows CIN2 or CIN3 (or HSIL, high grade lesion), the following treatment methods are available: 1. Total hysterectomy. This is the more aggressive management method, mainly used for older patients, no fertility requirements, no follow-up conditions. 2, re-conectomy. This is mainly used for younger patients with a small extent of conization (or LEEP) resection, positive extensive margins (HSIL), and more nervous patients. 3, repeat colposcopy + cervical canal scraping (ECC) in 2-3 months. This is mainly used in younger patients with better follow-up conditions. In summary, the majority of CIN patients who present with positive cut margins after CIN conization (or LEEP) can choose their treatment as they see fit and should not be nervous. It is important to know that the latest NCCN treatment guidelines in the United States clearly state that a positive margin after CIN conization (or LEEP) can be reviewed after 1 year.
