The role of wedge resection in contralaterality of benign cystic teratoma of the ovary.

Over a 5-year period, 402 women with benign cystic teratoma of the ovaries were seen at Siriraj Hospital. Fifty patients had bilateral ovarian tumors (12.44%). In 47 of these patients, bilateral involvement was evident on clinical examination. One hundred and seventy three patients with a visually normal opposite ovary had 3 (1.16%) identifiable tumors in that ovary by incidental ovarian operations. This 1.16% incidence of occult covert bilaterally is quite low and suggests that routine bivalving of wedge resection of a clinically normal opposite ovary is not necessary since peri-tubo-ovarian adhesion, pain and adhesion, pain and infertility are the common result. However, the possibility of such an occult tumor is not zero.
