Comparison of 2 Types of Cervical Specimens in Patients With a Pathological Screening Smear (ENDOCOL)

December 16, 2025 updated by: University Hospital, Lille

Endocervical Curettage Performed With a Kevorkian Curette Versus Cytobrush in Patients With ASC-H, LSIL, ASCUS HPV Positive and Non-contributory Colposcopy (ZT3) Smear or Atypical Pap Smear With Positive HPV Test

The recommendations on the method and the realization of the cervico-uterine smears are clear. With regard to performing endocervical curettage, several methods are possible without precise consensus. In general, the Kevorkian curette is widely used. However, it is often reported by doctors and patients that curettage is painful. Some articles show that the cytobrush would be less painful. While keeping a percentage of correct curettage failures, it is sought to show that the cytobrush would improve the comfort of the patient during curettage.

Description

Inclusion Criteria:

  • Women followed for a cervical pathology requiring endocervical curettage:
  • AGC type (glandular cell atypia) with positive HPV test

Design Details

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Kevorkian curette
Device: Kevorkian curette
the colposcopist holds the curette horizontally and scrapes the endocervical canal all the way around. He realizes 1 small firm and linear movement by quarter turn or 4 movements to realize a complete turn. During this act, the curette must remain inside the canal, and during its extraction, care should be taken not to rotate it so as not to spill the collected tissue contained in the basket of the curette. The tissue material thus obtained must be rapidly immersed in formalin
Experimental: Cytobrush
Device: Cytobrush
the brush would be inserted in full until the display of the brush in the endocervical canal disappears. A neck quadrant scan (= quarter turn) will be performed from front to back while simultaneously rotating the brush clockwise, for a total of 3 laps. This would represent 4 sweeps per turn, ie 12 sweeps in total
