UpToDate performs a continuous review of over 350 journals and other resources. Updates are added as important new information is published. The literature review for version 14.2 is current through April 2006; this topic was last changed on May 4, 2005. The next version of UpToDate (14.3) will be released in October 2006.
INTRODUCTION — The two Bartholin's glands secrete mucus to provide moisture for the vulva; they are the homologue of the bulbourethral glands in the male. These glands are located bilaterally in the vulvovaginal area at approximately the four and eight o'clock positions on the posterior-lateral aspect of the vaginal orifice (show figure 1). Each gland is approximately one-half centimeter (cm) in size and drains into a duct 2.5 cm long. The ducts emerge onto the vestibule, one at each side of the vaginal orifice, just below the hymenal ring. A normal Bartholin's gland is not palpable, except possibly in very thin women.
Cysts and abscesses are the most common disorders of the Bartholin's glands, occurring in 2 percent of women; carcinoma is rare [1]. However, many vaginal and vulvar lesions mimic Bartholin's gland disorders and should be considered in the differential diagnosis of a vulvovaginal mass (show table 1).
BARTHOLIN'S GLAND CYSTS — Chronic inflammation can obstruct the orifice of the Bartholin's gland duct. This leads to cystic dilatation of the duct, but not the gland, proximal to the obstruction.
Clinical manifestations and diagnosis — Bartholin's cysts average from 1 to 3 cm in size and are usually asymptomatic. Larger cysts may be associated with vulvar pain, discomfort during sexual intercourse, or difficulty sitting or ambulating.
The diagnosis is clinical and based upon findings of a soft, painless mass in the medial labia majora or lower vestibular area. Most such cysts are detected during a routine pelvic examination or by the woman, herself.
Treatment — No intervention is necessary for asymptomatic Bartholin's cysts, except in women over age 40 in whom a biopsy should be considered to exclude a carcinoma (see "Bartholin's gland carcinoma" below). Bartholin's cysts are usually sterile, thus they do not require antibiotic therapy [1].
Cysts that are disfiguring or symptomatic can be treated by the techniques illustrated below. There are no large clinical trials that provide data for guiding therapeutic decisions.
Incision and drainage — Incision and drainage may be performed with or without packing. The cyst should be lanced at or behind the hymenal ring to prevent vulvar scarring. However, we do not recommend this procedure alone since there is a tendency for cysts to recur because outflow is obstructed when the incised tissue e

es reapproximate.
Word catheter — Incision and drainage can be supplemented by placement of a Word catheter (show picture 1). This catheter is a balloon-tipped device that can be placed into the cyst cavity immediately after incision and drainage (show figure 2). The bulb of the catheter is then inflated and left in place for at least two to four weeks to promote formation of an epithelialized tract for drainage of glandular secretions; the end of the catheter is tucked into the vagina to minimize discomfort. The catheter can be removed in the office when the tract appears well epithelialized. In our practice, we try this method first as it can be performed as an outpatient procedure in the office or emergency ward setting under local anesthesia. (See "Word catheter placement for treatment of Bartholin's cysts and abscesses").
Marsupialization — Marsupialization refers to a procedure whereby a new ductal orifice is created by excising a 1 to 2 cm oval portion of the vulvar roof of the cyst behind the hymenal ring. The proximal duct wall is then everted onto the introital mucosa with sutures, thus creating a fenestration for egress of glandular secretions. This procedure can often be performed with local anesthesia (show figure 3) [2]. We resort to this method after failure of one or two placements of a Word catheter.
Sclerotherapy — Silver nitrate sticks can be inserted into the cyst cavity to necrotize the cyst wall. After incision and drainage, a crystalloid silver nitrate stick 0.5 cm in length and diameter is placed deep into the cavity. Mild burning may occur. After 48 hours, the patient returns to the office and the vulva is cleansed to reveal the incision site. Necrotized tissue with the remaining silver nitrate particles are removed.
In one report of 52 patients with either a Bartholin's cyst or abscess treated with this procedure, all patients showed complete healing within 15 days, although two women had recurrences within the first two months [3]. One of these patients was treated with excision and the other by repetition of the same method with no recurrences. In addition, a randomized controlled trial found silver nitrate insertion was as effective as excision of Bartholin's cysts or abscesses [4]. Comparison of sclerotherapy with more traditional and less invasive procedures than excision has not been performed. Studies that compare sclerotherapy with incision and drainage and Word catheter insertion and/or with marsupialization will help in deciding the role of sclerotherapy.
Excision — Excision of the entire Bartholin's gland and duct is the definitive procedure for both cysts and abscesses. It is usually considered after other methods have repetitively failed because it is not an office procedure and has higher morbidity, including excessive bleeding, hematoma formation, cellulitis, and dyspareunia.
