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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02500966
Recruitment Status : Completed
First Posted : July 17, 2015
Last Update Posted : January 18, 2020
Information provided by (Responsible Party):
Barretos Cancer Hospital

Brief 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.

Condition or disease Intervention/treatment Phase
Stenosis Cervix Device: DUDA device Procedure: LEEP Not Applicable

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.

Arm Intervention/treatment
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.)

Device: DUDA device
Insertion DUDA device

Procedure: LEEP
Loop Electrosurgical Excision Procedure

Active Comparator: Control group

The number of patients to be recruited in this arm will be 120.

Procedure: Loop Electrosurgical Excision Procedure (LEEP) without DUDA device

Procedure: LEEP
Loop Electrosurgical Excision Procedure

Primary Outcome Measures :
  1. Safety (two adverse events Grade 3 or 4 (CTCAE v. 4.0) or a single adverse event Grade 5) [ Time Frame: 3 months ]
    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.

  2. Cervical stenosis [ Time Frame: 6 months ]

    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

Secondary Outcome Measures :
  1. Pain Scales [ Time Frame: 6 months ]
    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).

  2. Complications [ Time Frame: 30 days ]
    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.

  3. View of the squamo-columnar junction (SCJ) of the cervix [ Time Frame: 6 months ]
    It will be assessed during the examination of colposcopy
