Role of preoperative ultrasound mapping in the surgical management of deep infiltrating endometriosis: a prospective observational study
Abstract Background Endometriosis is a challenging gynecological condition that has a profound influence on the quality of life of affected women. Transvaginal ultrasound is considered the first-line imaging method in preoperative assessment of the extent and severity of endometriosis. Accurate preo...

Precise mapping of DIE was done during TVS and laparoscopy. Results were correlated with histopathology findings. Results DIE was confirmed by histopathology in 88 patients. Sensitivity and specificity for individual DIE locations were rectovaginal septum 67.9% and 98.6%; vagina 52.2% and 98.7%; uterosacral ligaments 82.5% and 96.2%; torus 96.4% and 97.3%; parametrium 68.8% and 96.9%; rectum 100% and 98.8%; bladder 100% and 100%, ureters 63.4% and 99.0%; scar endometriosis 100% and 100%; pouch of Douglas obliteration 97.7% and 100%. No statistically significant difference was detected between ultrasound and histopathology size. Ultrasound tended to underestimate the lesion size; the underestimation was more pronounced for lesions > 3 cm. “Butterfly” and “tram-track” signs are two new sonographic signs related to posterior compartment DIE. No post-operative complications were recorded. There were no cases of DIE recurrence. Eleven out of 22 cases of infertility achieved pregnancy during 18 months follow-up.

An experienced radiologist can use E-PEP to provide an accurate demonstration of the location and extent of DIE which helps the surgeon select the most appropriate surgical approach ensuring radical treatment of the disease and minimizing short- and long-term complications.https://doi.org/10.1186/s43055-021-00526-wEndometriosisUltrasound imagingLaparoscopic surgery |
