The influence of peritoneal endometriotic lesions on the generation of endometriosis-related pain and pain reduction after surgical excision

To investigate the influence of different kinds of endometriotic lesions, especially peritoneal endometriotic implants in pain generation and the pain reduction after surgical excision in a prospective study.
Fifty-one pre-menopausal patients underwent surgical laparoscopy due to chronic pelvic pain, dysmenorrhoea and/or for ovarian cysts. In 44 patients, endometriosis was diagnosed. The pre- and post-operative pain score was determined using a standardized questionnaire with a visual analogue scale. Patients with peritoneal endometriosis were divided into two different groups depending on their pre-operative pain score: group A had a pain score of 3 or more, while group B a pain score of 2 or less. Patients without peritoneal endometriosis were classified as group C, and patients without endometriosis were classified as group D. The pre- and post-operative pelvic pain and/or dysmenorrhoea was analysed according to the different types of endometriotic lesions.
In groups A and C, the post-operative pain score decreased by at least 2 grades or more (p < 0.0). In group D, the post-operative pain score showed no significant reduction.
The present study suggests that the surgical excision of endometriotic lesions—including peritoneal implants—is an effective treatment of endometriosis-associated pelvic pain and/or dysmenorrhoea.
