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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety (two adverse events Grade 3 or 4 (CTCAE v. 4.0) or a single adverse event Grade 5) | 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. |
| Cervical stenosis | 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
| Measure | Time frame | Description |
|---|---|---|
| Pain Scales | 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). |
| Complications | 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. |
| View of the squamo-columnar junction (SCJ) of the cervix | 6 months | It will be assessed during the examination of colposcopy |
