Concurrent acute cystitis, pancolitis, and tubo-ovarian abscess following laparoscopic ovarian cystectomy: a case report.

BACKGROUND: Inadequate surgical interventions can lead to serious complications such as tubo-ovarian abscesses in the upper female genital system, often resulting from untreated pelvic inflammatory disease. Pelvic inflammatory disease, caused by infections like Chlamydia trachomatis and Neisseria gonorrhoeae, leads to scarring and adhesions in the reproductive organs, with common risk factors including intrauterine device use and multiple sexual partners. Pelvic inflammatory disease primarily affects sexually active young women and can manifest with varied symptoms, potentially leading to complications like ectopic pregnancy, infertility, and chronic pelvic pain if untreated. CASE PRESENTATION: This case report presents a unique scenario involving a 17-year-old sexually inactive female who experienced concurrent tubo-ovarian abscess, acute cystitis, and pancolitis following laparoscopic ovarian cystectomy. Pelvic inflammatory disease and its complications are well-documented, but the simultaneous occurrence of acute cystitis and pancolitis in this context is unprecedented in the medical literature. The patient's presentation, clinical course, and management are detailed, highlighting the importance of considering diverse and severe complications in individuals with a history of gynecological surgeries. CONCLUSIONS: Our case report highlights the need for healthcare professionals to remain vigilant for atypical presentations of gynecological complications and emphasizes the value of interdisciplinary collaboration for optimal patient care. We encourage further research and awareness to enhance understanding and recognition of complex clinical scenarios associated with gynecological procedures.

Tubo-ovarian abscess caused by Clostridioides difficile after eight months of surgery: Case report and review of extraintestinal abdominal abscess cases.

We present a case of tubo-ovarian abscess (TOA) caused by Clostridioides difficile (CD) in a 43-year-old female. Despite lacking a history of sexually transmitted diseases, the patient had undergone paraovarian cystectomy nine months before admission. Transvaginal ultrasonography performed eight months post-surgery revealed left ovarian enlargement, accompanied by subsequent lower abdominal pain and fever exceeding 38 °C. As oral antibiotic treatment was ineffective, the patient was admitted to our hospital. Computed tomography upon admission revealed a massive TOA. Surgical drainage of the abscess was performed, and CD was identified in the culture from the pus. The TOA was treated with a three-month course of metronidazole and oral amoxicillin/clavulanic acid. While CD is commonly associated with colitis, extraintestinal manifestations are exceptionally rare. This case represents the inaugural report of TOA resulting from CD. A literature review on abdominal and pelvic CD abscesses found that patients undergoing surgical drainage had a favorable prognosis. Therefore, surgical intervention plays an important role in the management of CD abscesses.

Risk factors for antibiotic therapy failure in women with tubo-ovarian abscess: A systematic review and meta-analysis.

AIM: Medical therapy with antibiotics only and surgical drainage are the treatment options of tubo-ovarian abscess (TOA). It is not yet known exactly which cases need surgical treatment. The aim of this systematic review and meta-analysis was to evaluate the risk factors leading antibiotic therapy failure in women with TOA. METHODS: We searched the following databases from inception to June 1, 2022: PubMed, Ovid MEDLINE, The Cochrane Library, and Scopus. We also searched reference lists of eligible articles and related review articles. The observational cohort, cross-sectional, and case-control studies were included in the meta-analysis. At least four review authors independently selected eligible articles, assessed risk of bias, and extracted data. The random effect model was used in the meta-analysis. RESULTS: A total of 29 studies, including 2890 women, were included in the study. The age, abscess size, history of intrauterine device use, postmenopausal status, history of diabetes mellitus, fever, white blood cell count, erythrocyte sedimentation rate, C-reactive protein level, and history of pelvic inflammatory disease were found as significant risk factors for antibiotic therapy failure in women with TOA. CONCLUSIONS: The findings of this study clarified the risk factors for antibiotic therapy failure in women with TOA.

Bilateral or unilateral tubo-ovarian abscess: exploring its clinical significance.

OBJECTIVES: To assess the characteristics of patients with unilateral and bilateral tubo-ovarian abscess (TOA). METHODS: Women diagnosed with TOA during 2003-2017 were included in this retrospective cohort study. TOA was diagnosed using sonography or computerized tomography and clinical criteria, or by surgical diagnosis. Demographics, sonographic data, clinical treatment, surgical treatment, and post-operative information were retrieved. RESULTS: The study cohort included 144 women who met the inclusion criteria, of whom 78 (54.2%) had unilateral TOA and 66 (45.8%) had bilateral TOA. Baseline characteristics were not different between the groups. There was a statistical trend that women with fewer events of previous PID were less likely to have with bilateral TOA (75.3% vs. 64.1%, respectively; p = 0.074). Women diagnosed with bilateral TOA were more likely to undergo surgical treratment for bilateral salpingo-oophorectomy compared to unilateral TOA (61.5% vs. 42.3%, respectively; p = 0.04). There was no difference in maximum TOA size between groups. CONCLUSIONS: This study detected a trend toward increased need for surgical treatment in women diagnosed with bilateral TOA. These findings may contribute to determining the optimal medical or surgical treatment, potentially leading to a decrease in the duration of hospitalization, antibiotic exposure, and resistance. However, it is important to acknowledge that the results of the current study are limited, and further research is warranted to validate these potential outcomes.

Endometriosis is a risk factor for recurrent pelvic inflammatory disease after tubo-ovarian abscess surgery.

PURPOSE: To evaluate the clinical outcomes and prognosis of patients undergoing laparoscopic surgery for tubo-ovarian abscess (TOA) and identify risk factors for pelvic inflammatory disease (PID) recurrence. METHODS: We conducted a retrospective cohort analysis including 98 women who underwent laparoscopic surgery for TOA at the Department of Obstetrics and Gynecology at the Bern University Hospital from January 2011 to May 2021. The primary outcome studied was the recurrence of PID after TOA surgery. Clinical, laboratory, imaging, and surgical outcomes were examined as possible risk factors for PID recurrence. RESULTS: Out of the 98 patients included in the study, 21 (21.4%) presented at least one PID recurrence after surgery. In the univariate regression analysis, the presence of endometriosis, ovarian endometrioma, and the isolation of E. coli in the microbiology cultures correlated with PID recurrence. However, only endometriosis was identified as an independent risk factor in the multivariate analysis (OR (95% CI): 9.62 (1.931, 47.924), p < 0.01). With regard to the time of recurrence after surgery, two distinct recurrence clusters were observed. All patients with early recurrence (≤ 45 days after TOA surgery) were cured after 1 or 2 additional interventions, whereas 40% of the patients with late recurrence (> 45 days after TOA surgery) required 3 or more additional interventions until cured. CONCLUSION: Endometriosis is a significant risk factor for PID recurrence after TOA surgery. Optimized therapeutic strategies such as closer postsurgical follow-up as well as longer antibiotic and hormonal therapy should be assessed in further studies in this specific patient population.

Image-guided drainage management of tubo-ovarian abscess and the role of C-reactive protein measurements in monitoring treatment response: a single-center experience.

PURPOSE: We aimed to compare the results of image-guided drainage in addition to antibiotic therapy (antibiotherapy) with antibiotherapy alone in the treatment of tubo-ovarian abscesses (TOAs) and evaluate C-reactive protein (CRP) levels in predicting the success of antibiotherapy. METHODS: This was a retrospective study of 194 patients hospitalized with TOA. Patients were divided into the following two groups: those who underwent image-guided drainage in addition to parenteral antibiotherapy and those who did not undergo image-guided drainage and received antibiotherapy alone. CRP levels on the day of admission (day 0), day 4 of hospitalization (day 4), and day of discharge (last day) were recorded. The percentage of decrease in CRP levels during day 4 and the last day compared with that on day 0 was calculated. RESULTS: A total of 106 patients (54.6%) underwent image-guided drainage with antibiotherapy, whereas 88 patients (45.4%) did not undergo drainage and received antibiotherapy alone. At admission, the mean CRP level was 203.4 (± 96.7) mg/L and was similar in both groups. The mean decrease in the CRP level on day 4 compared with that on day 0 was 48.5% and was statistically higher in the group that underwent image-guided drainage. Antibiotherapy failed in 18 patients, and a statistically significant difference was observed between treatment failure and the rate of decrease in the CRP level on day 4 compared with that on day 0. According to the receiver operating characteristic (ROC) analysis, if the CRP level measured on day 4 decreased by < 37.1% compared with that on day 0, the probability of treatment failure would increase (area under the curve = 0.755; 95% confidence interval, 0.668-0.841; sensitivity, 73.6%; specificity, 60%). CONCLUSIONS: Image-guided drainage combined with antibiotherapy in the treatment of TOA has high success rates, lower recurrence rates, and lower surgical requirement, and the mean decrease in the CRP level on day 4 can be monitored at treatment follow-up. In patients receiving antibiotherapy alone, if the CRP level on day 4 decreases by < 37.1%, the treatment protocol should be changed.

Ovarian Clear Cell Carcinoma and Rectal Adenocarcinoma Detected by Tubo-Ovarian Abscess: A Case Report.

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital. Laparoscopic abscess drainage was performed, and pathological findings confirmed the presence of ovarian clear cell carcinoma inside the abscess. The tumor marker carcinoembryonic antigen (CEA) was elevated, and rectal cancer was diagnosed by a gastrointestinal endoscopy. Abdominal computed tomography (CT) showed a left adnexal abscess with an air image inside, and penetration of the abscess wall and rectal cancer were observed. Histopathologically, there was an accumulation of neutrophils around the rectal tumor cells. We concluded that the rectal cancer had penetrated the existing ovarian tumor and formed TOA. Non-gynecological diseases may be associated with TOA. It is necessary to consider the possibility that other clinical diseases may be associated with the trigger of TOA.

Factors associated with an unfavorable clinical course in hospitalized patients with pelvic inflammatory disease: a retrospective cohort study of 117 patients from a Japanese academic institution.

BACKGROUND: This study aimed to determine the factors associated with an unfavorable clinical course (emergency surgery and/or prolonged hospitalization) in patients requiring hospitalization owing to pelvic inflammatory disease (PID). METHODS: A retrospective study was performed on 117 patients diagnosed with PID who were admitted to our hospital between January 2014 and December 2018. Multivariate regression analysis was conducted to determine the factors associated with emergency surgical intervention, and prolonged hospitalization in a subgroup of successful expectant management (n = 93). RESULTS: The average age (mean ± standard deviation) of the patients was 41.2 ± 12.5 years; 16 (13.7%) were postmenopausal; 81 patients (69.2%) complicated with a tubo-ovarian abscess (TOA) of which 59 (72.9%) had an ovarian endometrioma; and 19 patients (16.2%) had a history of various intrauterine manipulations. Emergency surgery was performed in 24 patients (20.5%), and patients with TOA underwent emergency surgery more often than did patients without TOA (25.9% vs. 8.3%, p = 0.03), and TOA was associated with longer length of hospital stay (17.1 days vs. 8.0 days, p = 0.01). Smoking, postmenopausal status, past medical history of PID, and high C-reactive protein (CRP) level at admission were significantly associated with emergency surgery. In patients with successful expectant management, obesity (body mass index ≥ 30) and high WBC and CRP level at admission were significantly associated with prolonged hospitalization. CONCLUSIONS: Of the patients requiring hospitalization owing to PID, TOA was associated with both emergency surgery and prolonged hospital stay. Patients with increased inflammatory markers and obesity should be considered to be at a high risk for unfavorable clinical course in the management of PID.

High risk and low prevalence diseases: Tubo-ovarian abscess.

INTRODUCTION: Tubo-ovarian abscess (TOA) is a rare but serious condition that carries with it a high rate of morbidity and even mortality. OBJECTIVE: This review highlights the pearls and pitfalls of TOA, including diagnosis, initial resuscitation, and management in the emergency department (ED) based on current evidence. DISCUSSION: TOA is associated with pelvic inflammatory disease (PID) as well as intrauterine devices, uterine procedures, multiple sexual partners, diabetes mellitus, and immunocompromised states. While usually arising from a gynecologic infection, TOA can be associated with a gastrointestinal source. History and physical examination are limited, demonstrating predominantly lower abdominal pain, but a minority of patients will present with vaginal symptoms. Half of patients will exhibit systemic illness to include fever, nausea, and vomiting. Laboratory evaluation may reveal elevations in white blood cell count and other inflammatory markers. Transvaginal ultrasound and computed tomography (CT) may be utilized for diagnosis, though CT has higher sensitivity and can differentiate this disease from similarly presenting gastrointestinal pathology. Initial medical management includes antibiotics. Surgical intervention is indicated in those who fail initial medical therapy, which is more likely in those with bilateral abscesses, large abscesses, and older patients. CONCLUSIONS: An understanding of TOA can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Laparoscopic Repair of a Colo-Ovarian Fistula.

OBJECTIVE: To demonstrate a laparoscopic approach to managing a colo-ovarian fistula. DESIGN: Narrated video outlining surgical technique. SETTING: Colo-ovarian fistulas are a rare entity with a lack of systematized evidence to guide surgical treatment [1-3]. Available case reports describe open en-bloc resection of the colon and adnexal organs with colorectal anastomosis [3]. We present a case of a colo-ovarian fistula managed laparoscopically with discoid resection of the fistulous tract, a technique used for rectosigmoid endometriosis [4]. INTERVENTION: A 51-year-old G0 presented with fevers, leukocytosis, and computed tomography imaging showing a peripherally enhancing adnexal complex highly suspicious for tubo-ovarian abscess that was refractory to antibiotics and interventional-radiology guided drainage. The patient elected for definitive surgery with hysterectomy, bilateral salpingo-oophorectomy, and indicated procedures.

Longitudinal change in serum inflammatory markers in women with tubo-ovarian abscess after successful surgical treatment: a retrospective study.

High levels of serum inflammatory markers are related to extended hospitalisation and more severe disease in the case of tubo-ovarian abscess (TOA). There is scarce information on the serial measurement of inflammatory markers during the postoperative follow-up period of surgically treated TOA. The present study aimed to assess the postoperative longitudinal changes in serum inflammatory markers following surgery for TOA. In this retrospective cohort study, patients who underwent surgery for TOA between January 2010 and March 2020 were reviewed. All inflammatory markers peaked within 48 hours after surgical intervention and then declined with time. The predicted mean of white blood cell count (WBC) to return to normal was 2.5 days (95% CI: 1.0-4.3), which was followed by neutrophil to lymphocyte ratio (NLR) (7.1 days, 95% CI: 4.7-10.8) and C-reactive protein (CRP) (+14 days). In conclusion, serum inflammatory markers increase in the very early post-operative period. While the normalisation period is very slow, it may not be appropriate to use CRP for evaluating the treatment success of TOA surgery. However, WBC and NLR measurements might be useful for follow-up and predicting the need for medical or surgical intervention.Impact statementWhat is already known on this subject? Serum inflammatory markers such as C-reactive protein, white blood cell count, and neutrophil to lymphocyte ratio are usually elevated in women with tubo-ovairan abscess, and high levels of these markers are associated with extended hospitalisation and more severe disease.What do the results of this study add? Our results indicate that the serum inflammatory markers increase and peak within the first 48 hours after surgery for tubo-ovarian abscess. Normalisation of white blood cell count is the fastest in successfully treated patients. However, normalisation of C-reactive protein is slowest, reaching 14 days and might not be as feasible as white blood cell count and neutrophil to lymphocyte ratio in postoperative patient follow-up.What are the implications of these findings for clinical practice and further research? The serum inflammatory markers should be interpreted with caution within 48 hours after surgical treatment for tubo-ovarian abscess. Instead of C-reactive protein white blood cell count, and neutrophil to lymphocyte ratio measurements can be preferred in post-operative follow-up to predict the need for further medical or surgical intervention.

The prediction of surgical intervention in patients with tubo-ovarian abscess.

The aim of this study was to compare the clinical characteristics of patients with tubo-ovarian abscess (TOA) who responded to medical treatment and those who underwent surgical intervention due to medical treatment failure. Electronic medical records were evaluated retrospectively to identify patients who were diagnosed with TOA. Demographic, clinical, and laboratory data including white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were compared between the medical treatment group and the surgical intervention group. Patient age, TOA diameter, WBC count, CRP, and ESR were significantly different between the groups. On multiple regression analysis, significant correlations were identified between age (p = .001), ESR (p = .045), and failure of medical treatment. TOA diameter (p = .065) showed a borderline association with surgical intervention. The risk of needing surgical intervention in TOA patients can be predicted using ESR in addition to age and TOA size as risk factors.IMPACT STATEMENTWhat is already known on this subject? For patients diagnosed with a tubo-ovarian abscess (TOA), the size of TOA and the patient's age are helpful for early identification of patients who are likely to need surgical treatment. Inflammatory markers such as C-reactive protein and white blood cell are also associated with the risk of surgical intervention.What do the results of this study add? Erythrocyte sedimentation rate (ESR) in addition to the size of TOA and the patient's age is a useful marker in determining whether to undergo surgery in patients with TOA.What are the implications of these findings for clinical practice and/or further research? ESR combined with the patient's age and the size of TOA is clinically useful in predicting the need for early surgical intervention in patients with TOA. Large prospective controlled studies are required to establish relationship between inflammatory markers and the risk of surgical intervention.

HEALTHCARE-ASSOCIATED TUBO-OVARIAN INFECTIONS IN UKRAINE: RESULTS OF A MULTICENTER STUDY (2020-2022).

OBJECTIVE: The aim: To determine the current prevalence of healthcare-associated tubo-ovarian infections in female and antimicrobial resistance of the responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and methods: We performed a retrospective multicenter cohort study was based on healthcare-associated infections surveillance data. Definitions of health¬care-associated tubo-ovarian infections were used from the CDC/ NHSN. The susceptibility to antibiotics was determined by disk diffusion method according to the EUCAST. RESULTS: Results: Among all the 1,528 of women in this study, the prevalence of healthcare-associated tubo-ovarian infections was 31.2%. Of these cases, Salpingitis, Oophoritis, and tubo-ovarian abscess were 47.5%, 34% and 18.5%, respectively. Of all cases tubo-ovarian infections in female, 74.7% were detected after hospital discharge. The predominant pathogens were: Escherichia coli (27.7%), Enterobacter spp. (12.2%), Klebsiella pneumoniae (9.6%), Staphylococcus aureus (8.2%), Pseudomonas aeruginosa (8.1%), and Enterococcus faecalis (7.5%), followed by Proteus mirabilis (5.1%), Streptococcus spp. (4.5%), Staphylococcus epidermidis (4.4%), and Acinetibacter spp. (4%). Methicillin-resistance was ob¬served in 16.8% of S. aureus (MRSA). No strains S.aureus and E. faecalis resistant to vancomycin. The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 24.7%. The prevalence of ESBL production among E. coli isolates was 28.6% and among K. pneumoniae 12.8%. Resistance to third-generation cephalosporins was observed in 14.9% E.coli and 11.3% K. pneumoniae isolates. Carbapenem resistance was identified in 11.3% of P.aeruginosa isolates. CONCLUSION: Conclusions: A healthcare-associated tubo-ovarian infections of the female in Ukraine is a common occurrence and many cases are caused by pathogens that are resistant to antibiotics.

Risk factors for the development of tubo-ovarian abscesses in women with ovarian endometriosis: a retrospective matched case-control study.

BACKGROUND: The purpose of this study was to assess the risk factors associated with the development of tubo-ovarian abscesses in women with ovarian endometriosis cysts. METHODS: This retrospective single-center study included 176 women: 44 with tubo-ovarian abscesses associated with ovarian endometriosis and 132 age-matched (1:3) patients with ovarian endometriosis but without tubo-ovarian abscesses. Diagnoses were made via surgical exploration and pathological examination. The potential risk factors of tubo-ovarian abscesses associated with ovarian endometriosis were evaluated using univariate analysis. The results (p ≤ 0.05) of these parameters were analyzed using a multivariate model. RESULTS: Five factors were included in the multivariate conditional logistic regression model, including in vitro fertilization, presence of an intrauterine device, lower genital tract infection, spontaneous rupture of ovarian endometriosis cysts, and diabetes mellitus. The presence of a lower genital tract infection (odds ratio 5.462, 95% CI 1.772-16.839) and spontaneous rupture of ovarian endometriosis cysts (odds ratio 2.572, 95% CI 1.071-6.174) were found to be statistically significant risk factors for tubo-ovarian abscesses associated with ovarian endometriosis. CONCLUSIONS: Among the factors investigated, genital tract infections and spontaneous rupture of ovarian endometriosis cysts were found to be involved in the occurrence of tubo-ovarian abscesses associated with ovarian endometriosis. Our findings indicate that tubo-ovarian abscesses associated with ovarian endometriosis may not be linked to in vitro fertilization as previously thought.

Perioperative Complications of Laparoscopic versus Open Surgery for Pelvic Inflammatory Disease.

STUDY OBJECTIVE: To compare complications in patients undergoing laparoscopic vs open surgery for acute pelvic inflammatory disease (PID). DESIGN: We performed a retrospective cohort study of patients who underwent surgery for PID, using the American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2015. Propensity score matching was used to balance baseline characteristics and compare complications in patients who underwent laparoscopic vs open surgery. SETTING: Surgical management of acute PID. PATIENTS: Patients with a preoperative diagnosis of PID were identified using International Classification of Diseases, Ninth Revision, codes. We excluded patients with chronic PID, gynecologic malignancy, and those for whom the surgical route was unknown. INTERVENTIONS: Surgery for acute PID. MEASUREMENTS AND MAIN RESULTS: The study included 367 patients. The mean age was 43.0 ± 11.1 years, body mass index was 30.9 ± 11.2 kg/m2, and American Society of Anesthesiology class was 2 (interquartile range 2-3). Preoperative signs of sepsis were noted in 33.8% of the patients, and septic shock was present in 1.4%. Hysterectomy was performed in 67.6%, oophorectomy in 12.0%, and salpingectomy in 4.6%. Complications were experienced by 114 patients (31.1%), 11 (3.0%) of which were potentially life-threatening. Multivariate logistic regression identified the following to be independently associated with complications: laparoscopy (adjusted odds ratio [aOR] 0.48; 95% confidence interval [CI], 0.3-0.8; p <.01), operative time (aOR 1.01; 95% CI, 1.00-1.01; p <.01), appendectomy (aOR 2.36; 95% CI, 1.0-5.4; p = .04), elevated international normalized ratio (aOR 2.30; 95% CI, 1.3-4.2; p <.01), and low hematocrit level (aOR 2.53; 95% CI, 1.4-4.5; p <.01). Propensity scores were calculated and used to generate a matched cohort of patients who underwent laparoscopic vs open surgery; the groups were similar, with p <.05 for all covariates. After balancing confounding variables, a laparoscopic approach to surgery remained significantly associated with a lower risk of complications (coefficient -0.07; 95% CI, -0.11 to -0.02; p = .008). CONCLUSION: Laparoscopy was associated with lower complication rates than open surgery in this well-matched cohort of patients who underwent surgery for acute PID.

A novel case of bilateral tubo-ovarian abscesses attributed to Ruminococcus gnavus without gastrointestinal involvement.

Ruminococcus gnavus is a Gram-positive anaerobe and normal gut commensal in the human host. There have been a small number of reported cases of infections attributed to R. gnavus, and no cases of urogenital infections have previously been published. We describe here a case of bilateral tubo-ovarian abscesses (TOAs) which cultured a pure growth of R. gnavus in a young female with concurrent deep infiltrating endometriosis and evidence of pelvic inflammatory disease. This case provides an insight into the behaviour of R. gnavus as a coloniser of the human host and provides further incentive to investigate its potentially pathogenic role in inflammatory conditions such as pelvic inflammatory disease.

Impact of early surgical management on tubo-ovarian abscesses.

This 5-year retrospective study aimed to investigate whether early surgical management improves outcomes in patients presenting with a tubo-ovarian abscess (TOA). Patient characteristics, investigation results and treatment outcomes were compared. 50 women were diagnosed with a TOA during the study period. Nineteen (38.0%) were treated with antibiotics (medical group) and thirty one (62.0%) were treated surgically on admission (early surgical group). The early surgical group was associated with a high success rate of 96.8% and the lowest risk of readmission within 12 months (16.1%). There was no significant difference in the length of stay between the early surgical and the successful medical group.Impact StatementWhat is already known on this subject? Tubo-ovarian abscess (TOA) is an inflammatory mass that forms most commonly as a complication of untreated pelvic inflammatory disease (PID). Traditionally, TOAs are treated first with broad-spectrum intra-venous antibiotics, with surgical intervention considered after 72 h. It is not known whether early surgical intervention would be beneficial to patient outcomes compared to traditional management.What do the results of this study add? In this study, we have demonstrated a high success rate with early surgical management. Readmission rate was lowest in the early surgical group compared to the medical and late surgical group. This suggests that early surgical intervention may be beneficial, compared to the standard management of trialling antibiotics and then proceeding to surgery 72 h later.What are the implications of these findings for clinical practice and/or further research? Our study suggests that early surgery may be beneficial in the management of TOAs. Although we were unable to demonstrate statistical significance, our data suggest that it would be worthwhile to investigate white blood cell (WBC) and C-reactive protein (CRP) further as a potential predictor for failure of medical management. In the future, more studies comparing early surgical management with medical and late surgical management could inform clinicians of the best mode of treatment for these patients.

Pelvic inflammatory disease among users and non-users of an intrauterine device.

The correlation between pelvic inflammatory disease (PID) and a present intrauterine device (IUD) has been debated. We aimed to evaluate the differences between IUD users and non-users among women hospitalised with a diagnosis of PID. Our hypothesis was that the role of a present IUD among PID patients is minimal, if any. We performed a retrospective cohort study during 2010-2018 in a tertiary university hospital. Overall, 474 hospitalised patients were diagnosed with PID. Of these, 121 patients were IUD users. The patients without an IUD were younger and had lower gravidity and parity. Among the patients without an IUD, higher rates of prior history of PID and fever at presentation were noticed. In 23.9% (29/121) of women, the IUD was inserted less than four weeks prior to the PID diagnosis. The patients with an IUD insertion-associated PID, had lower rates of tubo-ovarian abscess (2 (6.9%) versus 24 (26.0%), OR [95% CI] 0.18 (0.04-0.84), p = .02) at presentation, as well as a shorter length of stay (LOS) (median 4 versus 5 days, p = .05). In a patient in whom the IUD was retained, hospitalisation period was shorter (median LOS 4 days versus 5 days, p = .007). PID inpatients who carry an IUD represent a specific subset of patients with a milder disease.Impact statementWhat is already known on this subject? The correlation between pelvic inflammatory disease (PID) and a present intrauterine device (IUD) is debateable.What the results of this study add? PID inpatients who carry an IUD represent a specific subset of patients with milder disease.What the implications are of these findings for clinical practice and/or further research? Our results show that in IUD users with PID, the practice of IUD removal as part of their PID treatment is of little benefit.

The role of "penumbra sign" and diffusion-weighted imaging in adnexal masses: do they provide a clue in differentiating tubo-ovarian abscess from ovarian malignancy?

PURPOSE: To evaluate the role of "penumbra sign", diffusion-weighted imaging (DWI), and the apparent diffusion coefficient (ADC) value in differentiating tubo-ovarian abscess (TOA) from ovarian malignancy. MATERIAL AND METHODS: Thirty-six patients with 50 adnexal masses (tubo-ovarian abscess, n = 24; ovarian malignancy, n = 26), who underwent magnetic resonance imaging (MRI) with DWI, were retrospectively evaluated. "Penumbra sign" (hyperintense rim on T1W images), diffusion restriction, and mean apparent diffusion coefficient (ADC) values from cystic (c-ADC) and solid (s-ADC) components were evaluated for all the masses. RESULTS: "Penumbra sign" on T1W images was significantly more common in the TOA group (n = 21, 87.5%) than in the ovarian malignancy group (n = 2, 7.7%) (p < 0.001). Similarly, diffusion restriction in the cystic component was more frequent in the TOA group (n = 24, 100% vs. n = 2, 10.5%; p < 0.001). In contrast, diffusion restriction in the solid component was more common in the ovarian malignancy group (n = 5, 20.8% vs. n = 26, 100%; p < 0.001). The mean c-ADC value was significantly lower in TOAs (p < 0.001). A c-ADC value of 1.31 × 10-3 mm2/s may be an optimal cut-off in distinguishing TOAs from ovarian malignancies. Conversely, the mean s-ADC value was significantly lower in the ovarian malignancy group (p < 0.001). An s-ADC value of 0.869 × 10-3 mm2/s may be an optimal cut-off in differentiating ovarian malignancies from TOAs (p < 0.001). ROC curve analysis showed that c-ADC values had a higher diagnostic accuracy than s-ADC values. CONCLUSIONS: "Penumbra sign" on T1W images, diffusion characteristics, and ADC values provide important clues in addition to conventional MR imaging features in differentiating TOA from ovarian malignancy.

Can the Need for Invasive Intervention in Tubo-ovarian Abscess Be Predicted? The Implication of C-reactive Protein Measurements.

STUDY OBJECTIVE: To evaluate the clinical parameters of hospitalized patients with pelvic inflammatory disease (PID) for the presence of tubo-ovarian abscess (TOA) and predict the need for intervention. DESIGN: A prospective cohort study. SETTING: A tertiary care university medical center. PATIENTS: Ninety-four patients were diagnosed with complicated PID and hospitalized between 2015 and 2017. INTERVENTIONS: Patients with PID were treated with parenteral antibiotics according to Centers for Disease Control guidelines. Demographic, clinical, sonographic, and laboratory data for patients with PID were analyzed. Inflammatory markers including C-reactive protein (CRP), white blood cells (WBCs), erythrocyte sedimentation rate (ESR), and clinical parameters were collected at admission and during hospitalization. MEASUREMENTS AND MAIN RESULTS: Forty-eight of 94 patients (51.1%) hospitalized with complicated PID were diagnosed with TOA sonographically. CRP levels were the strongest predictor of TOA, followed by WBC count, ESR, and fever on admission. The areas under the receiver operating characteristic (ROC) curve for CRP, WBC, ESR, and fever were .92, .75, .73 and .62, respectively. CRP specificity was 93.4% and sensitivity was 85.4% for predicting TOA, with cutoff value of 49.3 mg/L. Twelve patients (25%) failed conservative management and underwent surgical intervention including laparoscopy (n = 7), computed tomography (CT)-guided drainage (n = 4), and laparotomy (n = 1). In this group, CRP levels significantly increased from admission to day 1 and day 2 during hospitalization (128.26, 173.75, and 214.66 mg/L, respectively; p < .05 for both). In the conservative management group, CRP levels showed a plateau from admission to day 1 and then a decrease until day 3 (110, 120.49, 97.52, and 78.45 mg/L, respectively). CONCLUSION: CRP is a sensitive, specific inflammatory marker for predicting TOA in patients with complicated PID, and levels >49.3 mg/L suggest the presence of TOA. In the TOA group, CRP level trends correlated well with success or failure of conservative management. Increasing CRP levels during treatment may be used as an indicator of the need for invasive intervention, and daily CRP measurements can help predict the need for invasive intervention.
