Definition
The Bartholin glands are located bilaterally on either side of the vaginal opening. These glandular structures produce a mucous secretion that contributes to lubrication of the vaginal vestibule. When the glandular excretory duct becomes obstructed, the secretion cannot drain properly and may accumulate within the gland, leading to the formation of a Bartholin gland cyst.
If the cystic content becomes infected, a purulent collection surrounded by inflammatory tissue may develop, configuring the clinical picture of a Bartholin gland abscess.
Bartholin gland cyst and abscess represent relatively frequent clinical conditions in gynecologic practice.
Causes
Clinical studies indicate that the Bartholin gland cyst primarily results from obstruction of the glandular duct, with consequent fluid accumulation. The obstruction may be caused by local inflammatory phenomena, infections, or trauma to the vaginal vestibule.
When the cystic content becomes infected, an abscess may develop. Several microorganisms can be involved in the infectious process. Among the most frequently isolated are Escherichia coli, a bacterium belonging to the intestinal flora, and pathogens responsible for sexually transmitted infections, such as Neisseria gonorrhoeae and Chlamydia trachomatis.
Symptoms
Small, uninfected Bartholin cysts may be completely asymptomatic and are often identified incidentally during gynecologic examination. When the cyst increases in volume, the patient may perceive a swelling or palpable mass near the vaginal introitus. An uninfected cyst is generally not painful but may be tender on palpation.
Cyst infection can evolve rapidly within a few days, with formation of an abscess. At this stage, the following may appear:
- Painful and tender swelling near the vaginal opening
- Discomfort while walking or sitting
- Pain during sexual intercourse
- Fever
In most cases, the cyst or abscess develops unilaterally, involving only one side of the vaginal vestibule.
In the absence of treatment, a cyst may become infected and progress to an abscess. If the purulent collection spreads to the surrounding tissues, systemic spread of the infection may occur, with possible sepsis. Specialist evaluation is indicated in case of progressive pain, fever, or rapidly evolving swelling.
Prevention
No specific strategies are available to prevent the formation of a Bartholin gland cyst. Some measures may help reduce the risk of cyst infection and subsequent abscess formation: adoption of safer sex practices, particularly the use of condoms, and maintenance of adequate intimate hygiene habits.
In women older than 40 years, in the presence of a Bartholin gland cyst, the physician may recommend a biopsy, with sampling of tissue for analysis to rule out vulvar malignancy.
Treatment
Treatment of Bartholin gland cyst or abscess depends on several factors, including the size of the lesion, the intensity of pain, and the presence of infection. In some situations, particularly with small and asymptomatic cysts, conservative measures may be sufficient.
When the cyst is voluminous or symptomatic, surgical drainage may be required. In the presence of infection, antibiotic therapy may be indicated to control the inflammatory process.
A minimally invasive therapeutic option is CO₂ laser treatment, used by Prof. Violante Di Donato in the management of these conditions. The laser allows vaporization and removal of the cyst while preserving the structure of the Bartholin gland. The procedure is generally performed in an outpatient setting and entails reduced recovery times.
Effectiveness of CO₂ laser treatment
In a study published in 2016, 31 patients were treated with CO₂ laser for Bartholin gland cysts in an outpatient setting. During the procedure, after skin incision, the laser beam allowed opening, drainage, and vaporization of the abscess cavity.
In the study, no intraoperative or postoperative complications were observed. Only 5 patients experienced a recurrence. Patients also reported minimal intraoperative pain.
The results indicate that CO₂ laser treatment can be safely performed in an outpatient setting, with low recurrence rates and high patient satisfaction. The minimally invasive approach allows preservation of the gland and reduces the risk of complications.
What to expect during and after treatment
Thanks to the minimally invasive approach, CO₂ laser treatment has an average duration of approximately seven minutes. The procedure begins with skin disinfection using antiseptic and administration of local anesthesia. The surgeon then uses the laser to perform small incisions allowing drainage of the abscess.
The cavity is then cleansed with sterile saline solution. During the procedure the laser vaporizes the tissue of the cystic capsule, reducing the risk of recurrence. Postoperative recovery is generally rapid, with resumption of daily activities in a short time.
Frequently asked questions
The Bartholin glands are two small mucous glands, normally the size of a pea, located bilaterally at the base of the labia minora in the posterior portion of the vaginal vestibule. Their excretory ducts open into the vestibule approximately at the 4 and 8 o'clock positions.
These glands contribute to lubrication of the vaginal vestibule, although their possible removal does not compromise overall lubrication thanks to the presence of other vestibular glands.
Ref.: [1, 2]
Initial symptoms of Bartholin gland inflammation include pain (56.9% of cases), local swelling (30.3%), and, less frequently, fever (12.7%). When the glandular duct becomes obstructed, a cyst may form; if infection occurs, an abscess develops.
Uninfected cysts may be asymptomatic, while abscesses cause intense pain and palpable swelling.
Ref.: [3, 4, 5]
Many uninfected and asymptomatic Bartholin cysts may regress spontaneously without specific treatment. Among conservative measures, warm sitz baths may be useful, as they promote spontaneous drainage of the gland and may relieve symptoms.
However, infected cysts or abscesses with a diameter greater than 2 cm rarely resolve spontaneously and require surgical drainage.
Ref.: [4]
Healing times vary depending on the therapeutic technique used. Marsupialization presents average healing times of approximately 4.3 ± 1.1 weeks, compared to approximately 6.7 ± 1.8 weeks for the Word catheter and 7.5 ± 2.0 weeks for incision and drainage. With appropriate treatment, clinical resolution generally occurs within two weeks.
Ref.: [6, 7]
Spontaneous rupture of an abscess can result in pus drainage and temporary improvement of symptoms. However, simple spontaneous drainage does not eliminate the cause of duct obstruction. In the absence of definitive treatment ensuring stable drainage, the risk of recurrence remains high.
Ref.: [5]
Medical or surgical treatment is indicated when:
- The cyst or abscess exceeds 2 cm in diameter
- Significant pain limits daily activities
- Signs of infection appear, such as fever, redness, or local warmth
- Cellulitis of surrounding tissues is present, requiring antibiotic therapy
- Recurrent episodes occur
Recurrences are reported in up to 37% of cases. The main associated factors include:
- Type of initial treatment: simple incision and drainage may have recurrence rates of up to 34.5%, while marsupialization is approximately 8.3%
- Escherichia coli infection, more frequent in recurrent forms (56.8%) compared to primary episodes (37%)
- Persistent obstruction of the glandular duct
- Same-side localization in 81% of recurrences
The average time to a new recurrence is approximately 32 ± 50 months.
Ref.: [6, 8]
Classical marsupialization is a surgical procedure that creates a permanent opening of the cystic cavity by suturing the cyst wall to the surrounding vestibular mucosa.
Alongside the traditional scalpel technique, the CO₂ laser may be used for fenestration, vaporization, or excision of the Bartholin gland cyst. Available data indicate that marsupialization is an effective procedure, associated with reduced recurrence rates, shorter healing times, and good tolerability for patients.
CO₂ laser treatment represents a minimally invasive procedure that can be performed in an outpatient setting for the management of Bartholin gland cyst or abscess. In a study published in 2016, 31 patients underwent CO₂ laser treatment. During the procedure, after a small skin incision, the laser beam allows opening of the cavity, drainage of the content, and vaporization of the cystic capsule. The procedure is generally performed under local anesthesia and has an average duration of approximately seven minutes.
In the study, no intraoperative or postoperative complications were observed. Only 5 patients experienced a recurrence and patients reported minimal intraoperative pain. These data indicate that CO₂ laser treatment can be safely used in an outpatient setting, with low recurrence rates, good tolerability, and rapid recovery times. Furthermore, the minimally invasive approach allows preservation of the gland and reduces the risk of complications.

Prof. Violante Di Donato, gynecologic oncology surgeon at Sapienza University of Rome, has published several scientific studies on the use of CO₂ laser in the treatment of Bartholin gland conditions:
- CO₂ laser therapy of the Bartholin's gland cyst: surgical data and functional short- and long-term results
- CO₂ laser treatment for Bartholin gland abscess: ultrasound evaluation of risk recurrence
- The impact of CO₂ laser for treatment of Bartholin's gland cyst or abscess on female sexual function: a pilot study
- Bartholin gland cancer
An association exists between Bartholin cysts or abscesses and certain sexually transmitted infections, particularly gonorrhea. One study reported Neisseria gonorrhoeae infection in 10% of patients with abscess, compared to 3% of patients without abscess.
However, the main cause of the condition is mechanical obstruction of the glandular duct rather than poor hygiene. The most frequently isolated pathogens are Escherichia coli (22–44%) and Streptococcus species (approximately 10%).
Ref.: [3, 8, 9]
The scientific literature does not identify specific preventive strategies for the formation of Bartholin gland cysts or abscesses. Some reasonable measures include:
- Screening and treatment of sexually transmitted infections
- Maintenance of adequate genital hygiene
- Timely treatment of symptomatic cysts
The choice of an appropriate surgical technique, such as marsupialization rather than simple incision and drainage, may contribute to reducing the risk of recurrence.
