Analysis of the Clinical Application Value of Colposcopy Biopsy in the Screening of Cervical Precancerous Lesions

Objective: To analyze the value of colposcopy biopsy in the screening of cervical precancerous lesions. Methods: 5,000 patients with suspected cervical precancerous lesions were used as samples. From January 2020 to December 2022, pathological examination and colposcopy biopsy were carried out, and the value of colposcopy biopsy was analyzed. Results: 1,503 cases were positive and 3,497 cases were negative by pathology, whereas 1,432 cases were positive and 3,568 cases were negative by colposcopy biopsy. The diagnostic sensitivity, specificity, and accuracy of colposcopy biopsy were 99.69%, 94.54%, and 97.78%, respectively. Cervicitis, CIN Ⅰ grade, CIN Ⅱ grade, CIN Ⅲ grade, and cervical cancer had no statistical difference with the pathological examination (P > 0.05). Conclusion: The colposcopy biopsy scheme is used in the screening of cervical precancerous lesions, the detection accuracy is high in consistency with the pathological results, the risk of missed diagnosis and misdiagnosis is low, and it is efficient and feasible.
