The structure, nature and intensity of painin various forms of external genital endometriosis

Abstract

Background. The study of the relationship of severity of endometriosis, localization and intensity of pelvic pain is a significant scientific interest. Aim of the study was to determine the structure of pain in women with external genital endometriosis (EGE) varying forms of distribution. Materials and methods. 124 patients were examined. Degree exam proliferation was assessed by endoscopy. Recovered: superficial endometriosis; endometrioid ovarian cysts; infiltrative forms of endometriosis; combined forms of endometriosis. Pain intensity was determined in accordance with a 10-point visual-analogue scale. Pain Detect scale was used to determine the nature of the pain. Statistical analysis of the material was carried out using the Microsoft Excel 2013 (Microsoft Corp., USA) applications and Stastistica 10.0 for Windows. Results. Light degree of pain intensity in patients with superficial forms EGE (92.11 %, 35 cases) is 21 times higher than that in patients with infiltrative forms (4.35 %, 1 case). Severe degree of pain intensity and with the same frequency is found at infiltrative (56.52 %, 13 cases), combined forms of endometriosis (57.14 %, 8 cases) and in patients with bilateral endometrioid cysts (47.37 %, 9 cases). Nociceptive pain is typical for patients with superficial forms EGE (73.68 %, 28 cases). Neuropathic pain occurs 4.5 times more frequently in patients with infiltrative (86.96 %, 20 cases) and combined forms of endometriosis (92.86 %, 13 cases). Conclusions. Light degree of pain intensity corresponds to the surface form of endometriosis, moderate and severe degree of pain equally common in infiltrative forms and endometrioid ovarian cysts, severe degree of intensity of the most common in infiltrative endometriosis and associated forms. By the nature of pain in superficial forms of endometriosis is dominated by complaints typical for nociceptive pain, neuropathic pain is more common in infiltrative endometriosis and associated forms.
