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.\nResults\nIn 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.\nConclusion\nThe 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.\nSimilar content being viewed by others\nReferences\nGiudice LC, Kao LC (2004) Endometriosis.
