## Core Concept
The treatment of Bartholin's abscess involves managing the infection and addressing the underlying cause. Bartholin's abscess is a common gynecological condition that occurs when the Bartholin glands, located on either side of the vaginal opening, become infected and form an abscess.

## Why the Correct Answer is Right
The correct answer, **Incision and drainage**, is the treatment of choice for Bartholin's abscess because it allows for the immediate relief of symptoms by draining the abscess. This procedure involves surgically opening the abscess to drain the pus, which helps to reduce pain, swelling, and the risk of further complications. After the procedure, the abscess cavity may be packed with gauze to help it heal from the inside out.

## Why Each Wrong Option is Incorrect
* **Option A: Antibiotics alone** - While antibiotics may be used as adjunct therapy to manage or prevent the spread of infection, they are not sufficient as standalone treatment for a Bartholin's abscess that has already formed. The abscess needs to be drained to resolve the infection.
* **Option B: Ultrasound-guided aspiration** - This method may be considered for a Bartholin cyst, but it is not typically the first-line treatment for a Bartholin's abscess.
* **Option D: Marsupialization** - Although marsupialization (a surgical procedure that creates a new pathway for glandular secretions to exit the body) can be a treatment for recurrent Bartholin cysts or abscesses, it is not typically the initial treatment of choice for an acute Bartholin's abscess.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that **Word catheter placement** can also be an effective treatment for Bartholin's cysts or abscesses. This involves placing a small catheter (like a Word catheter) into the cyst or abscess to allow continued drainage over several weeks. However, for an acute abscess, incision and drainage often provide more immediate relief.

## Correct Answer Line
**Correct Answer: C. Incision and drainage.**
