Review
A best evidence topic in general surgery was written according to a structured protocol, to address the question: in adult patients with perianal abscesses, should postoperative wound packing be undertaken considering the rates of pain experienced, wound healing and abscess recurrence? The literature search identified 159 papers on Ovid, Embase and Medline and 48 on PubMed. These were independently screened, and three articles were included in this review as these offered the best information to answer the question. One was a systematic review without meta-analysis, one was a randomised controlled trial and one was a multicentre observational study. Review of these articles led the authors to conclude that routine postoperative packing of perianal abscesses following incision and drainage is costly, associated with increased pain and confers no protection against recurrence of abscesses or formation of fistulae.

BACKGROUND AND STUDY AIMS
Liver abscesses are rare in the Western pediatric population and data on predisposing factors and etiology are scarce. We aimed to describe predisposing factors, microbiological characteristics, and treatment.
PATIENTS AND METHODS
Retrospective analysis of children admitted to two tertiary care hospitals in Belgium from 1 January 1996 to 31 December 2019. We analyzed clinical features, predisposing factors, imaging characteristics, microbiological data, treatment, and outcome in children with a liver abscess and compared these data with the literature.
RESULTS
We collected 24 cases with a male to female ratio of 1.4 and a median age of 3.2 years at time of diagnosis. Survival was 95.8%. Invasive culture specimens were obtained in 83.3% and showed growth of bacteria in 55%. Parenteral antibiotics were administered before invasive culture sampling in 80%. Liver abscesses were cryptogenic in four (16.7%) patients. Hepatobiliary disease was the most prevalent predisposing factor (n = 6; 25%), followed by recent antineoplastic therapy for malignancies (n = 5; 20.8%), intra-abdominal surgical pathology (n = 4; 16.7%) and umbilical venous catheters (n = 2; 8.3%). In two patients there was a parasitic origin (n = 2; 8.3%) and in one it was caused by Bartonellosis. There was no diagnosis of chronic granulomatous disease (CGD) in our cohort.
CONCLUSIONS
Pediatric liver abscesses have a favorable outcome in the developed world. Whenever feasible, invasive abscess culture specimens should be obtained. In patients presenting with a cryptogenic liver abscess or atypical disease course, immunological workup should be ensured.

INTRODUCTION
Subperiosteal orbital abscess (SPOA) is a serious suppurative complication of pediatric sinusitis. The objective of this study is to stratify patient selection into those best treated medically versus surgically based on clinical outcomes.
METHODS
This is a retrospective review of patients diagnosed with SPOA complicating sinusitis treated at a tertiary care pediatric hospital from 2002 through 2016. SPOA was diagnosed by CT scan. Characteristics evaluated include demographics, abscess size, location, and measurements, length of hospital stay, medical and surgical interventions, presenting symptoms, and complications.
RESULTS
A total of 108 total SPOA secondary to sinusitis patients were included. A majority, 72.2%, were male with an average age at presentation of 6.8 years. The mean ± standard deviation abscess cubic volume was 0.98 ± 1.27 cm (median(range) = 0.44(0.01-7.34 cmcm)). With an abscess volume of 0.510 cm, there was a sensitivity of 71.2% and a specificity of 84.4% for needing surgical drainage. Those with large abscesses at our volume threshold were 13 times more likely to require surgery than those with small abscesses, OR: 13.41, 95%CI: 5.02-35.86, p < .001. Patients that required surgery had an abscess closer to the orbital apex with the majority, 25 (61.0%), being the most proximal to the apex, p = .004. The likelihood of surgery decreased with increased distance from the orbital apex in medial abscesses (OR:.92, 95%CI: 0.86-0.98, p = .009).
CONCLUSION
In the pediatric population, SPOA is a serious consequence of sinusitis. This study provides evidence supporting that larger abscess size is a significant risk factor for requiring surgery. The appeal of our study is that it provides evidence and support that employ clinical parameters already assessed as standard practice in evaluating these patients. In summarizing the clinical translational relevance of our study, when determining whether to treat a patient with surgery and antimicrobial/medical therapy vs. non-surgical medical therapy alone, the clinician should focus on size of 0.510 cm or larger for abscesses in any location as a relative indication for surgery.

BACKGROUND
Perianal abscesses are a common surgical emergency. Due to their perceived ease, drainage is often delegated to junior trainees with varying levels of experience. The purpose of this study is to evaluate the current trend in perianal abscesses management at our institution, and identify factors that predict subsequent fistula formation or abscess recurrence.
METHODS
All acute patients admitted to a major teaching hospital who required surgical drainage of a perianal abscess were analysed over a two-year period from January 2019 to December 2020. Patient demographics, clinical and laboratory findings were retrospectively reviewed. Proceduralist experience, operative management strategy and recurrence rates (fistula or abscess) were analysed.
RESULTS
The mean age of patients was 43 years old, and 73% were male. Trainees performed 96% of the procedures. Re-presentation with a fistula or abscess recurrence requiring further surgery was 31%. Comorbidities of IBD, diabetes, or malignancy were present in one-third of patients and significantly increased the risk of recurrence (P = 0.01). Searching for a fistula tract was performed in 41% of cases but did not reduce recurrence (P = 0.9). Seton insertion occurred in 10%, and fistulotomy in 2%.
CONCLUSION
Perianal abscess drainage at our institution is almost exclusively performed by trainees, the majority of which occurs after-hours. Patients who present with a fever, inflammatory bowel disease, diabetes mellitus or malignancy are at an increased risk of recurrent abscess or a subsequent fistula after drainage, and input from an experienced surgeon may be of value when considering seton insertion or fistulotomy.

BACKGROUND
The purpose of this study was to identify risk factors for abscess formation in acute bacterial prostatitis, and to compare treatment outcomes between abscess group and non-abscess group.
METHODS
This is a multicenter, retrospective cohort study. All patients suspected of having an acute prostatic infection underwent computed tomography or transrectal ultrasonography to discriminate acute prostatic abscesses from acute prostatitis without abscess formation.
RESULTS
A total of 31 prostate abscesses were reviewed among 142 patients with acute prostatitis. Univariate analysis revealed that symptom duration, diabetes mellitus and voiding disturbance were predisposing factors for abscess formation in acute prostatitis. However, diabetes mellitus was not related to prostate abscess in multivariate analysis. Patients with abscesses <20 mm in size did not undergo surgery and were cured without any complications. In contrast, patients with abscesses >20 mm who underwent transurethral resection had a shorter duration of antibiotic treatment than did those who did not have surgery. Regardless of surgical treatment, both the length of hospital stay and antibiotic treatment were longer in patients with prostatic abscesses than they were in those without abscesses. However, the incidence of septic shock was not different between the two groups. A wide spectrum of microorganisms was responsible for prostate abscesses. In contrast, Escherichia coli was the predominant organism responsible for acute prostatitis without abscess.
CONCLUSION
Imaging studies should be considered when patients with acute prostatitis have delayed treatment and signs of voiding disturbance. Early diagnosis is beneficial because prostatic abscesses require prolonged treatment protocols, or even require surgical drainage. Surgical drainage procedures such as transurethral resection of the prostate were not necessary in all patients with prostate abscesses. However, surgical intervention may have potential merits that reduce the antibiotic exposure period and enhance voiding function in patients with prostatic abscess.

Surgery is the most important treatment for perianal abscesses. However, the gut microbiota of patients with perianal abscess and the effects of perianal abscess on the gut microbiota after surgery are unknown. In this study, significant changes in interleukin 6 and tumor necrosis factor- in the blood of healthy subjects, patients with perianal abscesses, and patients after perianal abscess surgery were identified. 16S rRNA gene sequencing technology was used to detect the changes in the gut microbiota among 30 healthy individuals and 30 patients with perianal abscess before and after surgery. Venn diagrams and alpha diversity analyses indicated differences in the abundance and uniformity of gut microbiota between the healthy individuals and patients with perianal abscesses before and after surgery. Beta diversity analysis indicated that the grouping effects among the control, abscess, and surgery groups were good. The classification and compositional analysis showed significant differences in the gut microbiota between healthy individuals and patients with perianal abscesses before and after surgery. LEfSe analysis, random forest analysis, and ROC curve analysis showed that (AUC = 0.7467) and (AUC = 0.72) could be potential biomarkers for the diagnosis of perianal abscess. The functional prediction results showed that the differential microbiota is significantly enriched in the pathways related to nutrition and drug metabolism. This study may have important implications for the clinical management and prognostic assessment of patients with perianal abscesses.

Review
BACKGROUND
Traditionally, emergency department (ED) physicians rely on their clinical examination to differentiate between cellulitis and abscess when evaluating skin and soft tissue infections (SSTI). Management of an abscess requires incision and drainage, whereas cellulitis generally requires a course of antibiotics. Misdiagnosis often results in unnecessary invasive procedures, sedations (for incision and drainage in pediatric patients), or a return ED visit for failed antibiotic therapy.
OBJECTIVE
The objective was to describe the operating characteristics of point-of-care ultrasound (POCUS) compared to clinical examination in identifying abscesses in ED patients with SSTI.
METHODS
We systematically searched Medline, Web of Science, EMBASE, CINAHL, and Cochrane Library databases from inception until May 2015. Trials comparing POCUS with clinical examination to identify abscesses when evaluating SSTI in the ED were included. Trials that included intraoral abscesses or abscess drainage in the operating room were excluded. The presence of an abscess was defined by drainage of pus. The absence of an abscess was defined as no pus drainage upon incision and drainage or resolution of SSTI without pus drainage at follow-up. Quality of trials was assessed using the QUADAS-2 tool. Operating characteristics were reported as sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-), with their respective 95% confidence intervals (CI). Summary measures were calculated by generating a hierarchical summary receiver operating characteristic (HSROC) model.
RESULTS
Of 3,203 references identified, six observational studies (four pediatric trials and two adult trials) with a total of 800 patients were included. Two trials compared clinical examination with clinical examination plus POCUS. The other four trials directly compared clinical examination to POCUS. The POCUS HSROC revealed a sensitivity of 97% (95% CI = 94% to 98%), specificity of 83% (95% CI = 75% to 88%), LR+ of 5.5 (95% CI = 3.7 to 8.2), and LR- of 0.04 (95% CI = 0.02 to 0.08).
CONCLUSION
Existing evidence indicates that POCUS is useful in identifying abscess in ED patients with SSTI. In cases where physical examination is equivocal, POCUS can assist physicians to distinguish abscess from cellulitis.

Journal of Ultrasound Dec 2022To explore the value of an ultrasound contrast agent (Sonovue) as an interventional treatment for periappendiceal abscesses.
OBJECTIVES
To explore the value of an ultrasound contrast agent (Sonovue) as an interventional treatment for periappendiceal abscesses.
METHODS
From January 2019 to December 2020, 30 patients were recruited who were admitted to Jinan Central Hospital due to periappendiceal abscesses. Before the operation, 2.5 ml of SonoVue contrast agent was injected intravenously to determine the non-enhanced area of liquefaction and necrosis in the abscess cavity. The puncture sites were selected. Percutaneous catheterization and drainage (PCD) were performed under contrast-enhanced ultrasound guidance. After the operation, 1 ml of diluted SonoVue suspension was injected through the drainage tube to observe the position of the drainage tube, the degree of drainage and the development of the abscess.
RESULTS
An ultrasound contrast agent was used preoperatively to assess the extent of the abscess. Liquefaction and necrosis were observed in the abscess cavity. CEUS showed hyperenhancement in the wall of the abscess in the arterial phase and the liquefied necrotic area in the abscess cavity was not enhanced before PCD. CEUS allowed operators to confidently identify the puncture site. Amongst the 30 cases of PCD, 27 cases showed the clear positioning of the drainage tube. The head of the drainage tube was placed in the ideal position and development could be seen in the abscess cavity. The diffusion effect of the contrast agent was good with no spillover and the drainage was unobstructed. Abscess development was observed in 3 patients after puncture injection of the contrast agent but the head of the drainage tube was not in the predetermined position. After adjusting the position of the drainage tube, CEUS was repeated and showed a strong diffusion effect of the contrast agent.
CONCLUSIONS
Intravenous injection of Sonovue before PCD of periappendiceal abscesses can evaluate the extent of the abscess, liquefaction and necrosis in the abscess cavity. The approach can also provide guidance for the placement of the drainage tube. After the operation, a diluted contrast agent was injected through the drainage tube. The position of the drainage tube and the flow direction of the contrast agent could be seen. This approach has good value for clinical applications to accurately judge the position of the drainage tube.

Review
BACKGROUND
Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus (PVL-SA) strains are frequently associated with large, recurring abscesses in otherwise healthy young individuals. The typical clinical presentation and the recommended diagnostic evaluation and treatment are not widely known.
METHODS
This review is based on pertinent publications retrieved by a selective search in PubMed, with special attention to international recommendations.
RESULTS
PVL-SA can cause leukocytolysis and dermatonecrosis through specific cell-wall pore formation. Unlike other types of pyoderma, such conditions caused by PVL-SA have no particular site of predilection. In Germany, the PVL gene can be detected in 61.3% (252/411) of skin and soft tissue infections with S. aureus. Skin and soft tissue infections with PVL-SA recur three times as frequently as those due to PVL-negative S. aureus. They are diagnosed by S. aureus culture from wound swabs and combined nasal/pharyngeal swabs, along with PCR for gene detection. The acute treatment of the skin abscesses consists of drainage, followed by antimicrobial therapy if needed. Important secondary preventive measures include topical cleansing with mupirocin nasal ointment and whole-body washing with chlorhexidine or octenidine. The limited evidence (level IIb) concerning PVL-SA is mainly derived from nonrandomized cohort studies and experimental analyses.
CONCLUSION
PVL-SA skin infections are easily distinguished from other skin diseases with targeted history-taking and diagnostic evaluation.

UNLABELLED
Kidney abscess is an unusual entity in childhood with few studies about its clinical characteris tics.
OBJECTIVE
To report the clinical presentation, diagnosis, and therapy used in a cohort of 20 children with kidney abscess.
PATIENTS AND METHOD
retrospective study of cases of kidney abscess during a 10-year period at the Hospital Roberto del Río. The analysis of clinical, laboratory, and imaging characteristics were evaluated as well as the treatment usedfor this condition.
RESULTS
20 cases were reported among which 65% were women with a median age of 3.6 years. The most com mon clinical presentation was fever, vomit, and dysuria. Eighty percent of patients presented an increase of inflammatory parameters, 88% presented positive urine culture, and the most common organism identified was Escherichia Coli (77.8%). The diagnosis was mostly made through kidney ultrasound (75%) followed by an abdominal CT scan (35%). 93% of abscesses were unilateral. About 95% of the patients only required antibiotic treatment. Vesicoureteral reflux was diagno sed in 28% of the patients with no sphincter control, and only one of them presented high-grade reflux. In patients with sphincter control, bladder and bowel dysfunction (BBD) was diagnosed in 90% of the cases. Forty four percent of the patients with late DMSA renal scintigraphy presented renal scarring.
CONCLUSIONS
In this series, pediatric kidney abscess appears with persistent fever despite the treatment, requiring prolonged antibiotic therapy and rarely surgical drains. We su ggest a study aimed at detecting modifiable factors, such as vesicoureteral reflux in patients with no sphincter control and BBD in patients with sphincter control, as well as identifying renal paren chymal sequels in all patients.
