Abstract

STUDY OBJECTIVE

To determine the distribution of ovarian dermoid cysts in a large series of women.

DESIGN

Observational study (Canadian Task Force classification II-3).

SETTING

University teaching hospitals.

PATIENTS

Three hundred thirty-six women.

INTERVENTION

Evaluation of operative reports.

MEASUREMENTS AND MAIN RESULTS

Dermoid cysts had a mean diameter of 5.6 cm. They were present in the right ovary (48.8 %), left ovary (37.8%), and bilaterally (13.4%). Unilateral cysts were more frequent in the right ovary (56.4%) than in the left (p = 0.002, odds ratio 1.7, confidence interval 1.2-2.3). This was significantly different from the expected 50% (4.45, chi2). A similar predisposition was found when we included women with bilateral cysts (p < 0.01, OR 1.5, CI 1.1-1.9). Patient age and size of cyst did not differ between those with left and right lesions.

CONCLUSION

In this large cohort of women, ovarian dermoid cysts had a predisposition to a right lateral location.

摘要

研究目的

确定大量女性中卵巢皮样囊肿的分布情况。

设计

观察性研究（加拿大工作组分类II-3）。

地点

大学教学医院。

患者

336名女性。

干预措施

评估手术报告。

测量指标及主要结果

皮样囊肿平均直径为5.6厘米。囊肿位于右侧卵巢（48.8%）、左侧卵巢（37.8%）以及双侧（13.4%）。单侧囊肿在右侧卵巢更为常见（56.4%），高于左侧（p = 0.002，优势比1.7，置信区间1.2 - 2.3）。这与预期的50%显著不同（χ² = 4.45）。当纳入双侧囊肿患者时，也发现了类似的倾向（p < 0.01，OR 1.5，CI 1.1 - 1.9）。左侧和右侧病变患者的年龄及囊肿大小无差异。
