A 30 years old multiparous woman is found to have a 5 — 6 cm cyst in one ovary. The most appropriate line of management would be :
**Core Concept**
The management of ovarian cysts involves a delicate balance between the risk of malignancy and the potential complications of surgical intervention. The decision to operate is often influenced by the size, symptoms, and ultrasound characteristics of the cyst.
**Why the Correct Answer is Right**
The correct answer is based on the principles of managing ovarian cysts in asymptomatic women. A 5-6 cm cyst is considered large enough to warrant surgical evaluation, but the patient is asymptomatic and multiparous, indicating a lower risk of malignancy. The surgical approach of choice is laparoscopic ovarian cystectomy, which involves the removal of the cyst while preserving the ovary. This approach minimizes the risk of adhesions, reduces the risk of ovarian failure, and allows for the preservation of fertility.
**Why Each Wrong Option is Incorrect**
**Option A:** Expectant management is generally reserved for small asymptomatic cysts (<4 cm) or those with a high risk of malignancy.
**Option B:** Ovarian tumor markers such as CA-125 are not specific enough to diagnose ovarian cancer and are not used to guide management.
**Option C:** Hormonal treatment with GnRH agonists or oral contraceptives may be used to shrink small cysts, but is not indicated for large cysts.
**Clinical Pearl / High-Yield Fact**
The "Rule of Twos" states that ovarian cysts 4 cm have a higher risk of malignancy. This can guide management decisions.
**Correct Answer: D.**
