Correlation between MR-semiotics and relapse of pelvic pain syndrome in patients with external genital endometriosis

Introduction. Endometriosis is a pathological process when tissue similar by morphological and function-al properties to the endometrium located outside the uterine cavity. Endometriosis presents with debilitating painful symptoms. Despite treatment, persistence and re-currence of symptoms of endometriosis is common. Diag-nostic imaging is essential for treatment planning. Clinical manifestation. To determine the relationship between the localization of foci of external genital endometrio-sis and relapse of pelvic pain syndrome. Materials and methods. А retro- and prospective analysis of MRI exami-nations of the pelvic organs in 80 patients with pelvic pain syndrome, aged from 24 to 39 years. The intensity of the pain syndrome was assessed using a visual analogue scale (VAS). The study involved patients with various localiza-tions of external genital endometriosis: ovarian endome-triosis, pelvic peritoneum endometriosis, broad ligaments, posterior pelvic compartment vis, rectum with deep and superficial invasion. Results. No statistically significant re-lationship between ovarian endometriosis and pelvic pain syndrome recurrence at 6 months (p=0.574). A statistically significant relationship was obtained between the endo-metrial implants in the retrouterine space and the recur-rence of pelvic pain syndrome (p <0.001). A statistically significant relationship was obtained between the depth rectal wall invasion in endometriosis of the retrouterine space between the recurrence of pelvic pain syndrome (p <0.001). A statistically significant relationship was found between recurrence of pelvic pain syndrome and endo-metriosis of the peritoneum (p=0.018) and endometriosis of the broad ligament (p=0.03). Conclusion. According to our study, the most recurrent pelvic pain syndrome lo-calizations of endometriosis according to MRI were: endo-metriosis of the retrouterine space, endometriosis of the peritoneum, round ligament of the uterus, endometriosis of the rectal wall. Statistically significant relationship was found between the depth of intestinal invasion and the recurrence of pelvic pain syndrome
