Bartholin Gland Cyst and Abscess

Why Incision and drainage with Word catheter is correct

• A symptomatic Bartholin abscess is treated with drainage; the standard outpatient procedure is incision at the mucocutaneous junction with insertion of a Word (balloon) catheter left in place for 4-6 weeks to allow epithelialization of a new ostium.
• This both relieves the acute abscess and lowers the high recurrence seen with simple drainage alone; antibiotics are generally not required after adequate drainage in a healthy, afebrile patient without surrounding cellulitis.

Why the others are wrong

• Oral antibiotics and warm sitz baths alone — antibiotics are reserved for surrounding cellulitis, immunocompromise, pregnancy, sepsis, or high MRSA risk; a fluctuant abscess needs drainage, not antibiotics alone.
• Surgical excision of the Bartholin gland — reserved for refractory or recurrent disease because of bleeding and dyspareunia risk; it is not first-line for an initial acute abscess.
• Observation with reassessment in two weeks — appropriate for an asymptomatic cyst, not an exquisitely tender abscess causing inability to sit or walk.
• Needle aspiration of the abscess cavity — aspiration is tempting as a quick, less invasive way to decompress the abscess, but it creates no lasting drainage tract: the puncture seals over, the duct stays obstructed, and the abscess often recurs; a Word catheter allows a new ostium to epithelialize.

Why A tender fluctuant mass at the posterior introitus is correct

• The Bartholin greater vestibular glands sit deep to the posterior third of the labia majora and drain through short ducts that open into the vestibule at roughly the 4 and 8 o'clock positions just outside the hymenal ring.
• Ductal obstruction traps mucus and produces a cyst, and secondary polymicrobial infection converts it to an abscess that enlarges rapidly over days and becomes exquisitely painful with sitting and ambulation.
• The expected finding is therefore a unilateral tender fluctuant mass at the posterior introitus, distorting the labium and the vestibule on one side while the contralateral side is normal.
• A tender fluctuant mass at the posterior introitus — the anatomic location of the Bartholin duct orifice, and fluctuance indicates a drainable abscess rather than a simple cyst.

Why the others are wrong

• Grouped vesicles on an erythematous vulvar base — primary genital herpes, which produces painful clustered vesicles and shallow ulcers with inguinal adenopathy rather than a solitary deep unilateral mass.
• A tender periurethral mass that drains pus with milking — a urethral diverticulum or infected Skene gland, which lies in the midline beneath the anterior vaginal wall and typically causes postvoid dribbling and dysuria.
• A firm mobile nodule within the right labium majus — an epidermal inclusion cyst or lipoma, which is chronic, nontender, and not fluctuant.
• A tense ecchymotic swelling of the right labium majus — a vulvar hematoma, tempting because it also causes painful unilateral labial swelling, but it follows blunt trauma such as a straddle injury, coitus, or delivery, which nothing in her history suggests, and its bluish discoloration would be obvious on inspection.

Treatment of an abscess is incision and drainage with Word catheter placement rather than simple lancing, and a new solid vulvar mass in a woman over 40 warrants biopsy to exclude carcinoma.
