Laparoscopic surgery for endometriosis: How often do we need to re-operate?

This study aimed to examine the rate of re-operation in women with endometriosis over a 10-year period. This was a retrospective study set in a university hospital in the UK. Notes of all women diagnosed with endometriosis were reviewed and data entered on a standard proforma. A total of 486 out of 988 procedures were for treatment of endometriosis. Some 240 (49%) had pelvic pain and 246 (51%) had subfertility. The mean age of those women who had a re-operation was lower than those who did not have any further operations. Using logistic regression, three factors were found to be the most important factors influencing the likelihood of women having re-operation - in decreasing order of importance, these factors were: (1) age, (2) pregnancy achievement and (3) improvement of symptoms. Re-operation occurred in 51% of our study population, the information may be useful for guidance of our patients.
