Hi, this is Tom from zerodefinals .com.
2
In this video, I'm going to be going through cervical ectropion.
3
And you can find written notes on this topic at zerodefinals .com slash
4
ectropion or in the gynecology section of the Zerodefinals Obstetrics and Gynae book.
5
So let's jump straight in.
6
Cervical ectropion can also be called cervical ectopy and cervical erosion.
7
Cervical ectropion occurs when the columnar epithelium of the endocervix, which is the canal of the cervix,
8
has extended out to the ectocervix, which is the outer area of the cervix that you can see on a speculum examination.
9
This means the lining of the endocervix becomes visible on examination of the cervix using a speculum.
10
This lining has a slightly different appearance to the normal ectocervix.
11
The cells of the endocervix, which are columnar epithelial cells, are more fragile and prone to trauma.
12
They're more likely to bleed with sexual intercourse.
13
This means cervical ectropion often present with post -coital bleeding.
14
Cervical ectropion is associated with higher estrogen levels
15
and therefore it's more common in younger women
16
and women on the combined contraceptive pill and also during pregnancy when there are higher circulating estrogen levels.
17
Next let's talk about the transformation zone
18
and the transformation zone is the border between the columnar epithelium of the endocervix
19
or the canal and the stratified squamous epithelium of the ectocervix
20
which is the outer area of the cervix that you can see on a speculum examination.
21
The transformation zone is essentially a border between the two types of epithelium.
22
When the transformation zone is located on the ectocervix,
23
it's visible during a speculum examination as a well -demarcated border between the two epithelial types.
24
Let's talk about the presentation.
25
Many cervical ectropion are asymptomatic and they're found incidentally during a speculum examination for another reason, for example during a smear test.
26
Ectropion may present with increased vaginal discharge, vaginal bleeding or dysparanunia which is pain during sex
27
Intercourse is a common cause of minor trauma to the ectropion triggering episodes of post -coital bleeding
28
Examination of the cervix will reveal a well demarcated border between the redder velvety columnar epithelium
29
that extends from the endocervix through the os, or the opening of the cervix,
30
and the pale pink squamous epithelium of the ectocervix, which covers the rest of the cervix.
31
This border is the transformation zone.
32
A tom tip for you, it's worth looking up photographs of cervical ectropion and becoming familiar with their appearance.
33
They're very common to see on speculum examination and could look alarming the first time you see one.
34
Ectropion are not associated with cervical cancer in any way.
35
It's worth getting familiar with distinguishing them from the appearance of cervical cancer.
36
If you see one, always ask about smears and if you're in any doubt,
37
get a senior opinion and consider referral for a colposcopy to look at the ectropion in detail.
38
Finally, let's talk about management.
39
Asymptomatic ectropion require no treatment.
40
Ectropion will typically resolve as the patient gets older, stops taking the combined pill or is no longer pregnant.
41
Having a cervical ectropion is not a contraindication to starting the combined contraceptive pill.
42
Problematic bleeding is an indication for treatment of cervical ectropion
43
and treatment involves cauterization of the ectropion using silver nitrate or cold coagulation during colposcopy.

需要注意的发音
说话人用了 5 次缩略和弱读形式，例如 they're, I'm, you're。请按听到的简短形式来说。

- 录下自己的声音并与原声对比，特别注意 examination, transformation, bleed 这类单词。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
