Q.how will you manage a TOA 9cm, with fever ,SIRS ?
Introduction
Complication of untreated PID (15% to 35%)
- Delay in treatment
- Virulent organism
Most common in women of reproductive age
Nulliparous 60%
Definition
- Inflammatory mass
- involving the tube and/or ovary
- Occasionally involve bowel bladder
- characterized by the presence of pus
Mortality (in severe sepsis) 5-10%
Aetiology
Polymicrobial 30-40%
- Ascending/upper genital tract infection →pus discharge in to peritoneal cavity through tubes →PID →TOA
- 2ry to other intra-abdominal pathology-Appendicitis , Diverticulitis ,Pyelonephritis
- Direct spread,
- Hematogenous spread

- STD-GC, Chlamydia, BV( GV,Pepto strepto coccus),
- E.coli, Hib
- TB-Mycoplasma tuberculosis, genitalium
- IUCD-Actinomyces
- Anaerobes-bacteroids
- GAS-Strep Pyo
- GBS-Strep Agalacties-GBS
Risk factors
- Age:>45 years more severe,
- Paradoxically Risk factors more in younger age
- Previous episode of PID –delay in treatment, virulence of the organism IUCD
- Sex
- Early onset
- Non-use of barrier contraception Earlier age at first sexual intercourse
- Multiple sexual partners
- Immune
- Diabetes
- Immunocompromised states
- Co-existing endometriosis ( eg more risk after OR for IVF: however routine Ab prophylaxis not indicated):theories Immune dysfunction. walls of endometriomas more susceptible for bac invasion than ovary cortex, blood act as good culture media
- OR in IVF introduce infection
Diagnosis
Clinical+ inflammatory +radiological markers
DD
Gyn | Non Gyn |
Endometrioma or other ovarian cyst malignancy Ectopic pregnancy | Appendicular massDiverticulitis |
Hx
- Fever +Diarrhea( TOA suggestive than PID)
- Abdominal/pelvic pain
- LOA
Vaginal discharge
- Presence/absence of risk factors
- Fertility wish
In severe cases
Tachycardia ,RR increases ,Low BP, High lactate So
— TOA more likely than PID
Ex
- Pyrexia
- Adnexal tenderness (bilateral or unilateral)
- Adnexal mass on abdominal palpation/bimanual examination
- Cervical discharge
- Cervical excitation
Ix
In all | Ill patients |
HCG in all reproductive age | |
Blood WBC Elevated WBC >15( higher than PID)Elevated ESR ( higher than PID)Elevated CRP( with clinical signs :most sensitive predictor TOA) Swabs– vaginal , rectal, urethral Positive Neisseria gonorrhoeae and/or Chlamydia trachomatis testsConsider HIV and other STI testing | Consider blood culture,CVS-lactate ,MAPRS- SpO2Coag- INR |
TOA more suggestive than PID- diarhrhea, Mass, CRP, WBC, ESR, USS cog wheel
Imaging
USS
First line imaging to guide diagnosis and treatment
Mass | complex /solid and cystic adnexal mass ( when withour pyrexia consider CA) |
Tube: | Pyosalpinx-elongated, dilated, fluid filled mass with partial septae and thick walls |
Cogwheel sign( tube)-sensitive marker of TOA: pathognomonic of acute tubal inflammation | |
Ovary | Tubovarian complex ovary =PCO appearance with adhered tube |
Uterus | Enlarged uterus with ill defined margins and endometrium |
FF | Echogenic complex FF |

“Cogwheel sign”- thickened endosalpingeal folds (pathognomonic of acute tubal inflammation)

Tubo-ovarian complex-inflammed ovary can acquire a reactive polycystic appearance because of oedema and adhere to tube to ovary. Lies in the D VS tumors which lie anterior superior to uterus

CT
- Adv:
- If USS is inconclusive or symptoms suggest other pathology
- Can see
- Details
- anteriorly displaced mesosalphinx
- septated tubal mass,
- thick peritoneum,
- thick uterosacrals( DD-endometriosis),
- hazy pelvic fat
- rectosigmoid involvement, ureter involvement( HU/HN)
- Help to refine the diagnosis
- Origin: Can see GI origin ,
- ovarian vein entering TOA sensitivity 94%, sp 100%( VS appendicular abcess),
- gas inside suggest bowel pathology eg.appendicular abcess,
- Disadv: delay in treatment
MRI
- Adv: Less radiation, higher sen 95% spe 89% than USS, good for pregß
- Diadv: More limited resource/not readily available/accessible
Management
MDT-CA, micro, radiology, venerology
HDU if ill


Initial management
- Admit and commence IV antibiotics
- Exclude systemic sepsis
- If +, “Sepsis Six” protocol
BUFALO
- Blood cultures
- Monitor UOP
- IV fluids
- IV broad spectrum antibiotics
- Measure serum Lactate
- High flow O2
If acute abdomen :may need immediate surgery
Do Quick assestment AMPLE FS, RF
Definitive management :
depends on stability, fertility wish, prev surgery, size of abcess, expertise
- Medical
- USS/CT guided drainage
- Surgical -salphigo oophorectomy
1.Medical
- IV broad spectrum antibiotics
- Ability to penetrate the abscess cavity
- Remain active within the abscess
- Be active against commonest pathogens
(IV clindamycin, metronidazole ,cefoxitin penetrate, active in abcess and reduce size)
Regimes

Duration
- Evidence is lacking
- Wait for 24 -48 hours to respond
- With Clinical improvement (70%), settling of pyrexiaàchange to oral and continue for 14 days , modify according to cultures
- Longer course needed- large abscess, after a gynecological intervention
Predictors of lack of response to medical therapy
- Size of abscess (>5cm)
- Age>40years
- Higher initial white cell count
- Smoking
2.USS/CT guided drainage
- Rapid symptom improvement,
- resolution of pyrexia,
- decreased length of hospital stay
- Minimally invasive and well tolerated
- Avoids risks associated with surgery and anaesthesia resolution with aspiration alone 88%
- Specimen for culture
- Disadv: High recurrence rate
Routes
- Transabdominal
- Transvaginal
- Transrectal
- Trans gluteal
USS guided aspiration | Catheter placement Indications |
Small, single abscess with clear fluids | Larger, bilateral, multiloculated abscess with thick viscous material |
3.Surgical
Indications
- Failure to respond to antibiotics 24 to 48 hours
- Acute abdomen with rupture of abscess is suspected
- Rapid clinical deterioration
- Chronic Abcess , >8cm
- Consider at low threshold for post menopausal due to risk of malignancy 47%( TOA in PM is rare 1.7%)
Role of diagnostic laparoscopy:
- Mild PID endometritis, salpingitis: subtle changes may miss on laparoscopy.
- If patient stable no need to do diagnostic laparoscopy on all PID. Medical Rx will suffice
Options
- Unilateral or bilateral Salpingo-oophorectomy ( no fertility wish)- Best
- Drainage
- Pelvic clearance ( more morbidity)
Routes (size of abscess, previous surgical history, fertility wishes, skills)
- Laparotomy
- Laparoscopy
Laparotomy | Laparoscopy | |
indication | Previous significant abdominal surgery Large abscess Co-existing eg. IBD | Fertility wishes |
Adv | thorough exploration of pelvis and bowelsThorough wash out of pelvis and abdomen with possible reduction in pus remnants Advances laparoscopic skills not required | Quicker recoverySmaller incisionsLess postoperative painMore fertility |
concerns | Intra op AbPus swabPut a large drain: drain forming pusTechnical difficult: morbidity | No routine diagnostic laparoscopy |
Technical difficulty
- Fragile necrotic tissue –difficult to handle result in tissues collapsing and haemorrhaging
- distorted anatomy :Oedema, thickened peritoneium- difficult to visualize and
- adherent ureter, bladder, bowel àdamage, internal iliac arteryà lacerations
- Consider
- Detailed consent
- interval surgery after 6 weeks of acute episode eg, persistant adenexial mass
Post op-
- Continue IV antibiotics and refine with the pus culture + ABST report
- Look for ileus and manage ( irritation, catheter tip)
- Monitoring
- 4 hourly observation,
- daily FBC and CRP,
- daily senior clinician review
- MEWS-vitals ,UOP
- Drain :monitor
- Counselling? Fertility à may need IVF
- Treat partners to prevent reinfection
- optimize nutrition: N/V/Appetite low
- DVT prophylaxis( stockings, LMWH if repeat Surgery unlikely)
- Fluctuating pyrexia –further imaging ( subphrenic, thoracic abcess)
Long term complications
Tissue damage, adhesions, scarring ,fistulae è SF, CPP, Ectopic
- Chronic pelvic pain
- One third of women with TOA
- Related to severity and number of episodes
- No change in medical or Sx Mx
- Subfertility
Laparoscopy and drainage ( better) | Medicle Antibiotics alone |
Fertility 32-63%Laparoscopy should be considered for all who wish fertilityConsider salpingectomy or occlusion at surgery in preparation for IVF( liase with fertility team) | Fertility 4-15% |
- Ectopic pregnancy
Special Circumstances-
Intrauterine devices
- Relationship between IUCD and Actinomyces israelii ( multi abcess ,granulation tissue and fibrosis)
- Well respond to penicillin
- Removal is associated with better short-term clinical outcomes
- Risk of pregnancy –need EC
Pregnancy TOA-
Fetal risk | Maternal |
MiscarriagePreterm labour ChorioamnionitisIUD | Death |
- Optimal treatment depends on severity of infection and gestational age
- Appendix abcess more common
- Ix-MRI to establish the diagnosis safe in pregnancy
