How to Avoid Cervical Stenosis After LEEP in High Grade Cervical Dysplasia?

An interventional study of DUDA device and LEEP in Stenosis Cervix, sponsored by Barretos Cancer Hospital. Completed at 1 site in Brazil. Open to female participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2020-01-18.

Study summary

Cervical stenosis may occur in up to 19% after conization. It is a cause of infertility and amenorrhea. This study will test a new device named DUDA Device ("Dispositivo Uterino para dilatar canal endocervical") placed just after the conization, in order to evaluate the safety, efficacy and quality of life.

Read the detailed description

This device has the potential to improve outcomes by means of a significant stenosis reduction and maintain patency of the endocervical canal to view the squamo-columnar junction (SCJ) of the cervix during follow-up of this patient.

Study arms

  • Experimental
    DUDA device

    The number of patients to be recruited in this arm will be 145. Note: The first twenty-five patients who will be included in the study will be allocated in the intervention arm to safety analysis (phase 1); after that all eligible candidates will be randomized 1:1 (phase 2). Procedure: Loop Electrosurgical Excision Procedure (LEEP) followed by implantation of the device called DUDA (plastic device developed in barretos cancer hospital that will be placed after conization. It has 2.5 cm in length and 5mm in diameter and remains within the endocervical canal for 30 days and is set at 4 points with nonabsorbable sutures in the ectocervix.)

What researchers measure

Primary outcomes

  1. Safety (two adverse events Grade 3 or 4 (CTCAE v. 4.0) or a single adverse event Grade 5)

    The main safety events to be considered in this analysis are vaginal bleeding and uterine infection. The device is considered unsafe and consequently disrupted the study if a two adverse events Grade 3 or 4 (CTCAE v. 4.0) or a single adverse event Grade 5 related to the procedure/device happens during the phase 1.

    Time frame: 3 months

  2. Cervical stenosis

    Stenosis of the endocervical canal (early and late) will be assessed by clinical information and physical examination at each visit to the hospital after surgery. The participant will be asked about the menstrual flow and dysmenorrhea during history taking. On physical examination, after the visualization of the cervix through the speculum examination, the doctor will check the channel permeability introducing a hysterometer through it. The difficulty of introducing the hysterometer 2.5mm the channel will be scored according to the following scale: Possible passage of hysterometer? () No difficulty () Little difficult, however possible passage of hysterometer () Unable to pass

    Time frame: 6 months

Secondary outcomes

  1. Pain Scales

    The quality of life will be evaluated through questionnaires by the Functional Assessment of Cancer Therapy - Cervix Cancer (FACT-Cx) and the universal pain assessment tools that include international scale and pain visual analogue (EVA), numerical visual pain scale (EVN) and faces pain scales (EF).

    Time frame: 6 months

  2. Complications

    It will be evaluated during the following returns and described as any event related directly to the use of DUDA device as metrorrhagia and uterine infection.

    Time frame: 30 days

  3. View of the squamo-columnar junction (SCJ) of the cervix

    It will be assessed during the examination of colposcopy

    Time frame: 6 months
