Tubo-ovarian abscesses (TOA) are one of the late complications of pelvic inflammatory disease (PID) and can be life-threatening if the abscess ruptures and results in sepsis. It consists of an encapsulated or confined ‘pocket of pus’ with defined boundaries that forms during an infection of a fallopian tube and ovary. These abscesses are found most commonly in reproductive age women and typically result from upper genital tract infection.[1][2] It is an inflammatory mass involving the fallopian tube, ovary and, occasionally, other adjacent pelvic organs. A TOA can also develop as a complication of a hysterectomy.[3]:103
Patients typically present with fever, elevated white blood cell count, lower abdominal-pelvic pain, and/or vaginal discharge. Fever and leukocytosis may be absent. TOAs are often polymicrobial with a high percentage of anaerobic bacteria. The cost of treatment is approximately $2,000 per patient, which equals about $1.5 billion annually.[1] Though rare, TOA can occur without a preceding episode of PID or sexual activity.[4][5]

Signs and symptoms
The signs and symptoms of tubo-ovarian abscess (TOA) are the same as with pelvic inflammatory disease (PID) with the exception that the abscess can be found with magnetic resonance imaging (MRI), sonography and x-ray.[1] It also differs from PID in that it can create symptoms of acute-onset pelvic pain.[6]
Cause
Chlamydia trachomatis and Neisseria gonorrhoeae are the most commonly implicated microorganisms. The development of TOA is thought to begin with the pathogens spreading from the cervix to the endometrium, through the salpinx, into the peritoneal cavity and forming the tubo-ovarian abscess with (in some cases) pelvic peritonitis. TOA can develop from the lymphatic system with infection of the parametrium from an intrauterine device (IUD).[1] Bacteria recovered from TOAs are Escherichia coli, Bacteroides fragilis, other Bacteroides species, Peptostreptococcus, Peptococcus, and aerobic streptococci.[7] Long term IUD use is associated with TOA.[8] Actinomyces is also recovered from TOA.[8]
Diagnosis
Laparoscopy and other imaging tools can visualize the abscess. Physicians are able to make the diagnosis if the abscess ruptures when the woman begins to have lower abdominal pain that then begins to spread. The symptoms then become the same as the symptoms for peritonitis. Sepsis, occurs if left untreated.[3]:103 Ultrasonography is a sensitive enough imaging tool that it can accurately differentiate between pregnancy, hemorrhagic ovarian cysts, endometriosis, ovarian torsion, and tubo-ovarian abscess. Its availability, the relative advancement in the training of its use, its low cost, and because it does not expose the woman (or fetus) to ionizing radiation, ultrasonography an ideal imaging procedure for women of reproductive age.[6]
Prevention
Risk factors have been identified which indicate what women will be more likely to develop TOA. These are: increased age, IUD insertion, chlamydia infection, and increased levels of certain proteins (CRP and CA-125) and will alert clinicians to follow up on unresolved symptoms of PID.[9]
Treatment
Treatment for TOA differs from PID in that some clinicians recommend patients with tubo-ovarian abscesses have at least 24 hours of inpatient parenteral treatment with antibiotics, and that they may require surgery.[1][10] If surgery becomes necessary, pre-operative administration of broad-spectrum antibiotics is started and removal of the abscess, the affected ovary and fallopian tube is done. After discharge from the hospital, oral antibiotics are continued for the length of time prescribed by the physician.[3]:103
Treatment is different if the TOA is discovered before it ruptures and can be treated with IV antibiotics. During this treatment, IV antibiotics are usually replaced with oral antibiotics on an outpatient basis. Patients are usually seen three days after hospital discharge and then again one to two weeks later to confirm that the infection has cleared.[3]:103
Complications
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
Complications of TOA are related to the possible removal of one or both ovaries and fallopian tubes. Without these reproductive structures, fertility can be affected. Surgical complications can develop and include:
- Allergic shock due to anesthetics
- A paradoxical reaction to a drug
- Infection
Epidemiology
The epidemiology of TOA is closely related to that of pelvic inflammatory disease which is estimated to one million people yearly.[11]
