Tubo-ovarian abscess (TOA), is a mass of inflammation in the ovary and fallopian tube, occurring typically after an upper genital tract infection in females of childbearing age.[1] It presents as a pelvic lump, low down tummy ache, vaginal discharge and fever.[1] There may be nausea and abnormal vaginal bleeding.[1] It is a late complication of pelvic inflammatory disease (PID), and can be life-threatening if it ruptures and results in sepsis.[2]

It consists of a walled off mass of pus with defined boundaries that forms in the fallopian tube and ovary.[2] It tends to occur following upper genital tract infection and [[PID}} in females of reproductive age who have sex.[2] It may involve adjacent pelvic organs.[1] A TOA can also develop as a complication of a hysterectomy.[3]: 103  Though rare, TOA can occur without a preceding episode of PID or sexual activity.[4][5] Infection from the cervix or vaginal spread up through the inner lining of the uterus and the fallopian tubes into the peritoneal cavity where it forms a walled-off mass, and often results in peritonitis.[2] A nearby infection such as of the appendix may less commonly extend to form a tubo-ovarian abscess.[2] Other risk factors include IUD insertion, multiple sexual partners, previous PID, and pelvic organ cancer.[2] It may be associated with diabetes and endometriosis.[1] Conditions that may appear similar include appendicitis, diverticulitis, pelvic inflammatory disease, ovarian torsion, inflammatory bowel disease, ectopic pregnancy, ruptured ovarian cyst, bladder infection, and kidney infection.[2] The most frequently reported bacteria isolated from tubo-ovarian abscessess include Escherichia coli, Bacteroides fragilis, Peptostreptococcus, Peptococcus, and aerobic streptococci.[2]

There maybe yellow-green discharge seen from the cervix when looking with a speculum.[2] It may hurt during an internal examination or when the cervix is moved.[2] A blood test usually reveals an elevated white blood cell count.[2] Other tests include pregnancy test, culture of urine, cervical discharge and blood, as well as a wet mount of vaginal discharge for clue cells.[2] An assessment of the abscess can be made using medical imaging; ultrasound, CT scan, MRI.[2] Diagnosis and assessment may be completed with a laparoscopy, during which it can be drained.[2] Treatment is initially with antibiotics given by injection.[2]

The cost of treatment in the United States is approximately $2,000 per patient, which equals about $1.5 billion annually.[6]

Signs and symptoms

Bacteroides fragilis

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.[6][7] It also differs from PID in that it can create symptoms of acute-onset pelvic pain.[8] Typically this disease is found in sexually active women.[4][9] Tubo-ovarian abscess can mimic abdominal tumours.[10]

Complications

Further information: Perioperative mortality

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:

Cause

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).[6] Bacteria recovered from TOAs are Escherichia coli, Bacteroides fragilis, other Bacteroides species, Peptostreptococcus, Peptococcus, and aerobic streptococci.[11] Long term IUD use is associated with TOA.[12] Actinomyces is also recovered from TOA.[12]

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.[8]

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.[14]

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.[6][15] 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  Ampicillin/sulbactam plus doxycycline is effective against C. trachomatis, N. gonorrhoeae, and anaerobes in women with tubo-ovarian abscess. Parenteral Regimens described by the Centers for Disease Control and prevention are Ampicillin/Sulbactam 3 g IV every 6 hours and Doxycycline 200 mg orally or IV every 24 hours, though other regiments that are used for pelvic inflammatory disease have been effective.[16]

Epidemiology

The epidemiology of TOA is closely related to that of pelvic inflammatory disease which is estimated to one million people yearly.[17]
