Abstract:

In recent years, due to the popularity of cervical screening, lesions associated with human papilloma virus (HPV) infection are mostly detected in the early stage, while the incidence of non-HPV-associated cervical lesions is increasing year by year, including gastric type endocervical adenocarcinoma with poor prognosis, which is often located in the middle and upper part of the endocervical canal. Endocervical canal lesions have a very high risk of infection because of its thin single-layer columnar epithelium and folds. And it is difficult to remove. Due to the particularity of the endocervical canal anatomy, cytological examination, virological examination, conventional colposcopy, and loop electrosurgical excision procedure (LEEP) biopsy cannot guarantee the satisfaction of the examination and the completeness of the lesions. It is easy to cause missed diagnosis, so the diagnosis of cervical canal lesions needs to be more accurate. This article will review diagnostic auxiliary examinations for this type of disease, such as endocervical sampling (colposcopy-endocervical sampling, LEEP-endocervical sampling and ultrasound-endocervical sampling), hysteroscopy and MRI, which still covers some controversial aspects.
