We investigated whether surgical methods, age, parity and obesity were correlated to endometriosis in patients who had hysterectomy.
This research was surveyed and reviewed of patients who underwent total abdominal hysterectomy, laparoscopic hysterectomy and vaginal hysterectomy in Kyungpook National University Hospital from 1999 to 2006, based on clinical recordings and pathologic reports. Based on these data, we investigated whether age, parity, obesity and pathologic diagnosis were correlated to prevalence rate of endometriosis. Also we investigated the correlations with anatomic lesion of endometriosis and surgical methods. SPSS version 12.0 chi- square test was conducted as the statistical data.
The total 4,830 cases of hysterectomy were undergone. Out of these, endometriosis was found at 125 cases (2.5%). Among them, 76 cases of endometriosis were found at 2,260 cases of abdominal hysterectomy (3.3%). 31 cases of endometriosis were found at 1,589 cases of vaginal hysterectomy (1.95%), and 18 cases of endometriosis were found at 981 cases of laparoscopic hysterectomy (1.83%). The correlation with laparoscopic hysterectomy and endometriosis had the statistically significant high rate (P<0.005). For anatomic site of endometriosis, 109 cases were found at ovary (87.2%), 7 cases were found at uterosacral ligament (5.6%), 4 cases were found at peritoneum (3.2%), 3 cases were found at cul-de-sac (2.4%), 3 cases were found at ovarian fossa (2.4%), 1 case was found at abdominal wall, rectal wall, vaginal wall and small intestine (0.8%), respectively. Age, parity, patologic diagnosis and obesity did not show the significant correlation with the prevalence rate of endometriosis (P>0.05).
Even the prevalence of endometriosis was low (2.5%) in total cases of hysterectomy, laparoscopic hysterectomy had more prevalence rate of endometriosis than other types of hysterectomy. because suspicious lesions were inspected carefully, Magnified laparoscopic view make us to identify suspicious endometriotic lesion more clearly than other type of hysterectomy.
