## Brief Summary

The recurrence of endometriosis after surgery a formidable challenge for the gynecologist. Recurrence rates reported in the literature are very high, being 21.5% at 2 years and 40-50% at 5 years. Several theories attempt to explain these high figures. The three most widely accepted are:

* The presence of residual endometriotic tissue or residual endometriotic cells not completely eradicated during surgery
* The growth of undetected microscopic endometriosis during surgery
* The development of endometriotic lesions de novo Patients with symptomatic endometriosis diagnosed by ultrasound or MRI and suitable for surgery will participate in the study. The surgical specimens sent for pathology from bladder, vagina, uterosacral, sigma or rectum will be properly marked for studying the presence of endometriosis.

## Detailed Description

Patients of Dexeus Universitary Institute that are having a laparoscopic surgery for deep endometriosis will participate in the study. A patient information sheet will be provided and written consent will be obtained. Patients who give written consent will participate in the trial. All patient information will be confidential and only be available to researches involved in the study.

Only three expert surgeons of the Gynecological Department of Dexeus Universitary Institute will participate in the study.
