Simulation Colposcopy – a practical way to teach colposcopy

new pic 3Students like practical ‘hands-on’ training not only in diagnosis but also in treatment. For diagnosis we have been using plastic simulation models which when looked at through the video colposcope, commonly used in India and the Middle East, appear as an exact replica of a real cervix. 

new pic 6This allows us to project images of the models onto a television screen where they seem identical to those seen with live colposcopy on a patient. We call this process ‘simulation colposcopy’ (#simulationcolposcopy).

At our Colposcopy Courses seminars in Dubai we hold a practical session on the last day where students are tested on their ability to use the colposcope and make diagnoses from models. They are also asked to demonstrate how they would use many of the ancillary instruments used in the colposcopic examination including endocervical forceps, biopsy forceps with local anesthetic and various specula.

We also ask them how they would treat this woman. After they have completed 5 stations, they are interviewed by an experienced colposcopist who reviews their answers. This is very similar to the OSCE exam which is used as part of the BSCCP accreditation.

The treatment session involves using an electro-diathermy loop (LLETZ). Animal tissue is used, usually beef or kidney because these have a similar consistency to the human cervix. When beef is used a circular piece is taken and the Key’s Punch is used to remove a few millimetres in the centre, imitating the normal endocervix. When acetic acid is placed on the meat it produces aceto whitening very similar to that seen on the cervix with the presence of abnormal tissue.

The same can be done with the kidney and these tissues are then placed in a short tube imitating the normal vagina and an electro-diathermy insulation pad is placed behind the tissue. A smoke extractor is incorporated into the model to remove the smoke produced during the excision process. In some models it is possible to place a vaginal speculum.

In London a similar practical training course has been developed at the Portland Hospital using a model developed by Anna Barbour, a nurse colposcopist.

The following pictures illustrate the different stages of the practical workshop.

screen 1.     Answering questions while viewing an image of a model using a video colposcope
 gynocular 2.     Using the Gynocular (a monocular colposcope) to view the models
phone 3.     Using the Gynocular with a smart phone attached which can take a high quality colpo-photograph. Additional data can also be collected on the smartphone, including patient details, biopsy position, Swede score. All of which can be stored in the cloud and emailed. It is extremely useful for teaching and audit purposes and is light weight (450g) and easily transportable.

low_grade 6.     Low grade, pre-cancer from which a #biopsy was accidentally taken by a candidate who thought it was real.

ibc20151The Dubai #ColposcopyCourses are offered by our partner companyIBC Medical, an independent training institute which runs workshops and hands-on courses for a variety of medical and surgical specialities including. It also offers training for those undertaking the RCOG membership examinations.
