Colposcopic RCI is the quantitative scoring index of electronic colposcopy, and the score of 1 is considered to be caused by cervical columnar epithelial ectasia, which is a physiological phenomenon, and patients usually have no obvious symptoms. Some patients may have symptoms such as increased leukorrhea and contact bleeding, which can be treated with electrocoagulation and cryotherapy. Colposcopic RCI score 1 is the result of a colposcopic biopsy and refers to cervical epithelial sarcomatoid neoplasia (CIN) grade I. The patient may have cervical columnar epithelial ectasia. Cervical columnar epithelial ectasia is a normal physiologic variant, and most patients have no obvious symptoms, while some patients show increased leukorrhea, contact bleeding, and lower abdominal pain. Generally do not need special treatment. If the patient’s symptoms are more serious, he should seek medical treatment in time. Electrocoagulation can be taken, which contacts the surface of the cervical lesion through an electrocautery device to make it fall off, or cryotherapy, which rapidly generates a low temperature through a refrigerant to make the lesion tissue necrotic and fall off. When a patient has a colposcopy with an RCI score of 1, no special treatment is usually needed. If the patient has increased leukorrhea and other uncomfortable symptoms, they should seek medical attention and follow the doctor’s instructions.
