Correlation study of lesion anatomical characteristics and pain symptoms in patients of ovarian endometriosis cyst

Objective To explore the anatomical distribution characteristics of pelvic endometriosis lesion,size of the cyst,tissue adhesion degree and the correlation with the pain symptoms in patients with ovarian endometriosis cyst. Methods 342 cases of patients with ovarian endometriosis cyst who has underwent gynecologic laparoscopic surgical treatment in our hospital were selected as the research objects.According to the pain symptoms,they were divided into the pain group(195 cases) and the painless group(147 cases). The influence of cyst growth area and size on the pain symptoms were compared,and whether there were cyst adhesion and the relationship between adhesion area and pain were analyzed. Results The operation time of pain group was longer. The average operation time was 81. 2 min in pain group while it was 62. 1 min in painless group. The bleeding volum was 74. 3 mL in pain group which was higher than 56. 2 mL in the painless group. The average diameter of cyst was 11. 26 cm in the Pain group,and it was 6. 10 cm painless group. Rate of adhesions in patients of pain group was significantly higher than that of the painless group. Adhesion occured most frequently in ovary,followed by the fallopian tubes. Conclusion Pain symptoms have a close relation with cyst diameter and degree of surrounding tissue adhesion. As the cyst diameter get larger and the surrounding tissue adhesions grow broader,the pain symptoms would be more significant in patients.
