Clinical Trial Summary

This is a single-center, prospective diagnostic-accuracy study. All women who will undergo surgery for DE after preoperative ultrasound for six consecutive months will be included. Anamnestic and preoperative (physical objective and ultrasonographic) data of these patients will be collected. Surgical and pathological data will be analyzed to confirm the presence of parametrial DE.

Description:

This is a single-center, prospective diagnostic-accuracy study. All women who will undergo surgery for DE after preoperative ultrasound for six consecutive months will be included. Anamnestic and preoperative (physical objective and ultrasonographic) data of these patients will be collected. Surgical and pathological data will be analyzed to confirm the presence of parametrial DE.

All the study procedures are done according to our clinical practice. Demographic and ultrasonographic data will be collected from the preoperative evaluation, which is routinely done at our institution by four ultrasonographic expert in diagnosing deep endometriosis. Surgical and pathological data will be collected during surgical procedures and hospital stay.
