[Clinical aspects of mature ovarian teratoma: result of 695 cases].

Abstract

OBJECTIVE:

To evaluate the clinical aspects of mature ovarian teratoma.

METHOD:

We retrospectively studied 695 patients operated in PUMC Hospital between January 1990 and December 2000.

RESULTS:

Laparoscopy surgery had shorter hospitalization day, less blood loss during surgery, shorter operation time compared with laparotomy (P < 0.001). Routine contralateral wedge resection was done in 601 cases, among which 459 had normal inspection and palpatation. Only one (0.22%) was pathologically confirmed bilateral tumor. Torsion was the major complication (7.5%). Average tumor size of torsion was (10.2 +/- 4.5) cm. Probability of torsion increased as the tumor enlarged, which was less than 4.4% when the tumor size was less than 6 cm and greater than 10% if size greater than 8 cm. Rupture, infection, and malignant transformation were rare.

CONCLUSIONS:

Laparoscopy is superior to laparotomy in the treatment of mature ovarian teratoma. If the contralateral ovarian is within normal configuration, contralateral wedge resection is unnecessary. When the tumor size is greater than 8 cm in diameter, it will have more chance to twist.
