**Core Concept**
Endocervical polyps are benign growths that arise from the cervical canal, often causing abnormal vaginal bleeding. The treatment of choice aims to remove the polyp while preserving the surrounding tissue and maintaining normal cervical function.

**Why the Correct Answer is Right**
Polypectomy is the preferred treatment for endocervical polyps due to its effectiveness and minimal invasiveness. This procedure involves the removal of the polyp through a diagnostic procedure like colposcopy or a minor surgical intervention. The polyp can be removed using a loop electrosurgical excision procedure (LEEP) or by sharp dissection. This approach allows for the removal of the polyp while preserving the surrounding cervical tissue and maintaining normal cervical function.

**Why Each Wrong Option is Incorrect**

* **Option A:** Vaginal hysterectomy is an extensive surgical procedure involving the removal of the uterus and vagina, which is not indicated for the treatment of endocervical polyps.
* **Option B:** Conisation refers to the removal of a cone-shaped sample of tissue from the cervix, which is often used for diagnostic purposes or to treat cervical intraepithelial neoplasia (CIN). It is not the treatment of choice for endocervical polyps.
* **Option D:** Radiotherapy is a treatment that uses ionizing radiation to kill cancer cells and is not indicated for the treatment of benign conditions like endocervical polyps.

**Clinical Pearl / High-Yield Fact**
It is essential to differentiate between endocervical polyps and cervical cancer, as the latter requires a more aggressive treatment approach. A thorough histopathological examination of the removed polyp is necessary to rule out any malignant changes.

**✓ Correct Answer: C. Polypectomy**
