## Brief Summary

Association between the ultrasound appearance of deep bowel endometriosis and the frequency of pain

## Detailed Description

In order to improve the diagnostic power of the ultrasound method, it is important to evaluate the association between the ultrasound appearance of the nodule of intestinal deep endometriosis and the frequency of pain, thus assessing the prevalence of moderate or severe clinical symptoms, in patients with newly diagnosed intestinal deep endometriosis, according to the ultrasound morphology of the posterior deep endometriosis nodule proposed in the International Deep Endometriosis Analysis Group (IDEA) Consesus.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** FEMALE
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Patients aged ≥18 years;
* Presence of posterior rectus intestinal deep endometriosis confirmed on TV ultrasound between 01/01/2018 and 30/06/2023;
* Informed consent obtained

Exclusion Criteria:

* Virgo patients;
* Patients reporting intolerance to transvaginal ultrasound;
* Current or history of gynaecological oncology;
* Previous surgery of the sigma and rectum
```

## Primary Outcomes

- **Prevalence of moderate or severe clinical symptoms** _(time frame: At diagnosis or in the previous 6 months)_ — Prevalence of moderate or severe clinical symptoms in patients with newly diagnosed deep bowel endometriosis according to the ultrasound morphology of the posterior deep endometriosis nodule proposed in the IDEA Consensus.

## Secondary Outcomes

- **Ultrasound morphologies of the intestinal endometriosis nodule and the frequency of associated lesions** _(time frame: At diagnosis or in the previous 6 months)_
- **Association between ultrasound morphology and specific clinical symptoms** _(time frame: At diagnosis or in the previous 6 months)_
