Epidemiology and Treatment of Surgical Infection after Ankle Arthroscopy: A Systematic Review.

Background: Ankle arthroscopy is indicated for both diagnosis and treatment of a large spectrum of common ankle disorders. It has certain advantages over the open procedure; however, it is important to recognize that there are some complications associated with it. Infections after this procedure are quite uncommon, with an overall estimated incidence of 2%. Given the low incidence of infections after ankle arthroscopy, not a great deal of literature on the topic has been published. The present review aims to provide an overview of the incidence, diagnosis, and treatment of infections after ankle arthroscopy. Methods: A systematic review of the literature indexed in the PubMed, MEDLINE, and Cochrane Library databases using search term "ankle arthroscopy infections" was performed in November 2023. No restrictions were applied concerning the date of publication. The Preferred reporting items for systematic reviews and meta-analyses (PRISMA) were followed. Among all surgical operations for the treatment of ankle and foot pathologies, we included articles with a described superficial or deep infection after ankle arthroscopy. Results: The search resulted in 201 studies. Only 21 studies met our inclusion criteria, and they were included in this systematic review. We evaluated 1706 patients who underwent 1720 arthroscopic tibiotalar procedures at an average age of 42 years old. Out of the 1720 procedures, 41 (2%) were complicated by infection. We divided infectious complications into superficial (68%; 28/41) and deep (32%; 13/41) infections. The most common pathogen isolated was Staphylococcus aureus. Arthroscopic arthrodesis was found to be the most affected by deep infections. Conclusions: Infection after ankle arthroscopy is an uncommon complication. Superficial infections were successfully treated with antibiotics, while surgical debridement, arthroscopic drainage, and intravenous antibiotics were necessary in cases of deep infections. Considering the amount of information on pathogens associated with knee and shoulder infections, there is still a lack of literature on pathogens associated with ankle infections, which makes their management difficulty.

Principles of Empirical and Therapeutic Antimicrobial Therapy

The goal of this review is to discuss basic principles for the appropriate use of antibiotics in the surgical patient, largely focusing on the treatment of intra-abdominal infections. Limited pharmacologic data on common antibiotics are provided. Current reference sources and institutional guidelines should be used for specifics on dosing and administration. This review covers general principles, including treatment of surgical infections, laboratory tests, pharmacokinetics and pharmacodynamics, adverse reactions, antimicrobial resistance, and antibiotic prophylaxis in surgical patients. In addition, specific considerations of appropriate antimicrobial therapy, such as acute cholecystitis/cholangitis, pancreatitis, appendicitis, diverticulitis, Clostridium difficile, and skin and soft tissue infections are presented. Tables list high-risk factors in intra-abdominal infections, empirical antibiotic based on risk stratification for the treatment of community-acquired intra-abdominal infections, dose adjustments for obese patients, most common isolated pathogens from intra-abdominal infections, 2005–2010, with resistance trends, adaptation of Tokyo guidelines on severity scoring and recommended antimicrobial therapy, and recommended antibiotics for necrotizing soft tissue infections.

Different Surgeon, Different Duration: Lack of Consensus on the Appropriate Duration of Antimicrobial Prophylaxis and Therapy in Surgical Practice.

Background: The principles of antimicrobial stewardship promote the appropriate prescribing of agents with respect to efficacy, safety, duration, and cost. Antibiotic resistance often results from inappropriate use (e.g., indication, selection, duration). We evaluated practice variability in duration of antimicrobials in surgical infection treatment (Rx) or prophylaxis (Px). Hypothesis: There is lack of consensus regarding the duration of antibiotic Px and Rx for many common indications. Methods: A survey was distributed to the Surgical Infection Society (SIS) regarding the use of antimicrobial agents for a variety of scenarios. Standard descriptive statistics were used to compare survey responses. Heterogeneity among question responses were compared using the Shannon Index, expressed as natural units (nats). Results: Sixty-three SIS members responded, most of whom (67%) have held a leadership position within the SIS or contributed as an annual meeting moderator or discussant; 76% have been in practice for more than five years. Regarding peri-operative Px, more than 80% agreed that a single dose is adequate for most indications, with the exceptions of gangrenous cholecystitis (40% single dose, 38% pre-operative +24 hours) and inguinal hernia repair requiring a bowel resection (70% single dose). There was more variability regarding the use of antibiotic Px for various bedside procedures with respondents split between none needed (range, 27%-66%) versus a single dose (range, 31%-67%). Opinions regarding the duration of antimicrobial Rx for hospitalized patients who have undergone a source control operation or procedure varied widely based on indication. Only two of 20 indications achieved more than 60% consensus despite available class 1 evidence: seven days for ventilator-associated pneumonia (77%), and four plus one days for perforated appendicitis (62%). Conclusions: Except for peri-operative antibiotic Px, there is little consensus regarding antibiotic duration among surgical infection experts, despite class 1 evidence and several available guidelines. This highlights the need for further high-level research and better dissemination of guidelines.

Aortic Complications Related to Mycobacterium bovis after Intravesical Bacille Calmette-Guérin Therapy - a Systematic Review

Aortic complications after intravesical Bacillus Calmette-Guérin (BCG) application are a rare complication of the treatment of non-muscle invasive bladder cancer. The aim of this systematic review was to perform a descriptive analysis of previously published studies and to discuss the particular challenges of diagnosis and treatment of this rare complication. A literature search was performed in PubMed (1949-2021) and Web of Science (1900-2021) using the search terms "mycobacterium" OR "bovis" OR "BCG" AND "aorta" OR "aneurysm". In a staged review process, publications with the following inclusion criteria were included in data analysis: original paper, full-text availability in English or German and aortic complication after intravesical BCG instillation. We focused on the analysis of BCG-specific medical history data as well as treatment strategies in relation to patient outcome and the occurrence of graft infections during follow-up. A total of 60 individual cases were described in 55 published articles. BCG-induced mycotic aortic aneurysms can occur in all segments of the thoracoabdominal aorta, but the infrarenal aortic segment was most commonly affected (65% of cases). The most common configuration was saccular outpouchings (65%). Concomitant infections in other tissues were typical (65%). Patients with mycotic aneurysm presented with or without consecutive aortic rupture in 28% and 63%, respectively. Diagnosis was based on a combination of pathological and microbiological examinations. A common treatment algorithm was surgical infection treatment (85%) and antitubercular therapy (83%). Performed simultaneously, they resulted in a long-term survival of 81%. Graft infection after initial aortic repair with alloplastic material (n=40) developed in ten patients (25%) during follow-up. Diagnosis of mycotic aneurysms or vascular complications after intravesical BCG application is exceptionally challenging and a high level of suspicion is required. Diagnosis is based on obtaining sample material of affected regions and the combination of patient's history, clinical presentation and pathological or microbiological examinations. Currently, no consensus guideline for optimal medical treatment options of aortic complications secondary to BCG instillation exists. The combination of surgical treatment and supportive antitubercular therapy seems to achieve the best results. Since the risk of prosthetic infection after the use of alloplastic materials remains high (25%), we strongly suggest evaluating autologous or allogenic aortic replacement during initial aortic repair.

Clinical profile of patients on prophylactic parenteral antibiotics with combined parenteral and pre-operative intra-incisional antibiotic administration in reducing surgical site infection

A number of observations by nineteenth-century physicians and investigators were critical to our current understanding of the pathogenesis, prevention, and treatment of surgical infections. In 1846, Ignaz Semmelweis, a Magyar physician, took a post at the Allgemein Krankenhaus in Vienna. He noticed that the mortality from puerperal (

Rational antimicrobial therapy and wound healing stimulation in patients with surgical infection

The objective of the study was to develop the problem of complex treatment of surgical infections of the skin and soft tissues (SISST).The studies were carried out in 201 patients with SISST who were treated at the Department of Purulent Surgery of the Hospital Surgery Clinic of the EE “Vitebsk State Medical University” in 2017–2020. As a result, it was developed: a protocol for a rational use of antibiotics in the patients with SISST, an effective regimen for use of antiseptic drugs, a method for treating purulent wounds with autologous bone marrow aspirates.For 13 years, there have been significant changes in the etiological structure of gram-negative problematic pathogens in patients with purulent wounds. The share of K.pneumoniae increased approximately 8 times (by 12.25 %; p < 0.05), and A.baumannii ‒ 9 times (by 14.69 %; p < 0.05). The share of MRSA remained virtually unchanged. The resistance of problem microorganisms to almost all antibacterial drugs significantly increased. For MRSA-induced SISST, glycopeptides (vancomycin) should be recommended as a drug of choice, and oxazolidinones (linezolid) and glycylcyclines (tigecycline) should be recommended as a reserve; K. pneumoniae ‒ colistat and tigecycline; P. aeruginosа ‒ carbapenems (doripenem) and colistat; A. baumannii ‒ penicillins or cephalosporins with sulbactam (ampicillin + sulbactam) and colistat.It was found that septomyrin and 0.02 % chlorhexidine bigluconate have the greatest activity against the leading representatives of the microflora of purulent wounds. With a combined use of septomirin and chlorhexidine, the bacterial contamination of wounds decreased below the critical level already on the 2nd day after surgical treatment (p < 0.01).To stimulate wound healing, sternocentesis is performed and automyeloaspirate is taken. The curettage of the wound and the aspirate introduction into the wound edges and the application to the wound surface are performed. It has been established that, along with the pelvic bones, the sternum can be an alternative source of red bone marrow. The myeloaspirate volume obtained by sternal puncture varied from 10 to 140 ml. The developed method allows us to reliably reduce the duration of the 2 phase of the wound process by 7 days (р < 0.01).

Use of ornidazole in the treatment of anaerobic infection in surgery

One of the most complex problems of modern surgery is the treatment and prevention of anaerobic infection. Main place in overcoming of this infectious complication is devoted to urgent surgical intervention and correct early empiric antibacterial therapy. Special place in the combined empiric antibacterial treatment is devoted to 5-nitroimidazoles. Modern data about clinical efficacy of ornidazole in the treatment of surgical infectious complications is presented in the article. We performed a comparison of therapeutic activity and physical-chemical properties, pharmacokinetic and pharmacodynamic features of ornidazole with the first representative of 5-nitroimidazole class – metronidazole. Taking into account antiprotozoal and antianaerobic activity of ornidazole, it is recommended to be used in the schemes of combined therapy of severe generalized anaerobic infections and purulent processes of different localization; treatment and prevention of surgical infections after intraabdominal, thoracic, proctological and dental surgical interventions.

Clinical Evaluation a New Treatment for Infection After Ventriculoperitoneal Shunt.

To explore a new surgical treatment for infection and obstruction of ventriculoperitoneal shunt in hydrocephalus. Two cases of post-operative infection of ventriculoperitoneal shunt were analyzed retrospectively. One case was cryptococcal infection, the other case was Acinetobacter lwoffii. The number of cerebrospinal fluid cells was high, the infection of ventriculoperitoneal shunt was generally complicated with abdominal obstruction, and the hydrocephalus was aggravated again, The authors try to pull out the drainage tube at the end of abdominal cavity for external drainage, combined with intravenous antibiotics, completely control of infection, and then use the original shunt device for intraventricular jugular shunt. The authors explore that this method is simple, safe and effective, and it is an effective and feasible method for the treatment of infection after ventriculoperitoneal shunt.

Bacteriophage Therapy as a Potential Management Option for Surgical Wound Infections.

To investigate the potential role of bacteriophages in the treatment of surgical infections, we conducted a retrospective analysis of four surgical patients who have sought treatment at the Eliava Phage Therapy Center, Tbilisi, Georgia. Two patients had chronic osteomyelitis, one presented with a diabetic foot ulcer, and the fourth patient had developed a severe infectious complication after skin grafting surgery. Patients were treated with different combinations of bacteriophage preparations, based on the sensitivity of the isolated bacterial strain toward commercially available bacteriophages. The treatment lasted on average for 1 month, and positive results were obtained in all four cases: the wounds have healed, the general health status of the patients has improved. No allergic or adverse reactions have been observed throughout the treatment.

Treatment of CSF leakage and infections of dural substitute in decompressive craniectomy using fascia lata implants and related anatomopathological findings

Purpose Decompressive craniectomy (DC) is widely used to treat raised intracranial pressure (ICP) in cranial trauma and stroke. It is accompanied by numerous complications. The aim of our study is to assess the surgical treatment of infections related to the use of a dural substitute with concurrent CSF leakage performed at our institution. Material and methods A retrospective analysis of a series of 72 patients who underwent DC between 2011 and 2017 was performed. Seven cases (9%) showed infection related to the use of xenograft (bovine pericardium) and coexisting CSF leakage. Epidural/subdural empyemas were observed in seven cases; three in conjunction with an intracerebral abscess. For reconstruction, free anterolateral thigh fascia lata flaps were used, based on the size of the defect. Results After removal of the dural substitute and the implant of free fascia lata, infection and CSF leaks resolved in all. An anatomopathological examination of the implant at the later time of cranioplasty (CP) showed the tissue had become vascularized exhibiting integration with the native dura. No complications related to the harvesting of the fascia lata were observed. Conclusions Fascia lata is a validated source of autologous grafts; it is cost-free and would appear to be the biological material most similar to the dura mater. The implanted material appears to maintain a lasting vitality when covered over with a well-vascularized scalp, even after a period of months, achieving a successful suppression of infection. Subsequent skull reconstruction is performed safely and easily using artificial bone.

Modern problems of modelling and treatment of soft tissues abscesses

Increase of the frequency of soft tissues pyoinflammatory diseases and purulent-septic complications against the background the antibiotic-resistance of organism dictates the necessity of search of rational new surgical technologies and preparations with the intense bactericidal effect. Period of the connective tissue (cicatrix) formation on a place of wound defect of the operated purulent abscess of soft tissue (PAST) is defined by the speed of the granulations and epithelial tissue formation. Therefore, one of the task of experimental surgery is search of new methods of the effective postoperative influence on terms of the regeneration and complete obliteration of the PAST cavity. The perspective direction in treatment of surgical infection is application of metals nanoparticles. In treatment of pyoinflammatory processes it is applied the preparation Eplan and also zinc oxide nanoparticles which have bactericidal, antiinflammatory and regenerative effects. However, till now it was not carried out experimental works on modelling and surgical treatment of PAST with local application of the laser technologies in combinations with Eplan and metals nanoparticles.

Surgical Treatment of Chronic Osteomyelitis

Introduction.In this study, we analysed the results of applying various surgical methods in the combined treatment of inflammatory diseases of bones and joints.Materials and methods.The work was based on data from a multi-dimensional cohort study using non-concurrent (historical) control. A retrospective study included the analysis of medical records covering the period of 2009–2016 (1059 patients). A prospective study consisted in analysing the effectiveness of modern surgical methods in the combined treatment of inflammatory diseases of bones and joints in patients hospitalised to the Septic Surgery Department of the G.G. Kuvatov Republican Clinical Hospital (Ufa, Russia) in 2017–2018 (285 patients).Results and discussion.An analysis of the authors’ own data revealed that injuries (73.21%) and infectious complications after receiving surgery on bones and joints (15.03%) are the most common causes of osteomyelitis. In most cases, the following list of measures is optimal for diagnosing suspected osteomyelitis of various etiologies: X-ray, general clinical tests supplemented by the fistulography or CT of the affected area prior to surgery, as well as the examination of surgical material after surgery. The use of modern methods for surgical debridement and surgical repair of bone defects in the combined treatment of patients with chronic osteomyelitis can significantly reduce the relapse rate. It is recommended that patients with osteomyelitis be treated at large in-patient surgical facilities, which include a specialised department for the treatment of surgical infections and corresponding support services.Conclusion.Apparently, there is no one most optimal method for treating osteomyelitis. The optimal effect in the treatment of osteomyelitis is achieved through a personalised set of therapeutic measures using the following methods: laser vaporisation, negative-pressure wound therapy, ultrasonic cavitation in the focus of inflammation, as well as surgical repair of the post-trepanation bone defect or wound.

390. Treatment and Outcome of Methicillin-Resistant Staphylococcus aureus Hip and Knee Prosthetic Joint Infection

BackgroundMethicillin-resistant Staphylococcus aureus (MRSA) total hip and knee prosthetic joint infections (PJI) can be highly morbid and difficult to treat. Other clinical factors notwithstanding, explantation is usually recommended, although comparative treatment data are lacking. We sought to compare the success of implant retention to two-stage exchange in MRSA-infected PJI to better understand treatment options in this difficult cohort.MethodsA retrospective cohort of hip and knee PJIs from 2009 to 2016 were identified by ICD code and surgical treatment. All cases met MSIS criteria for PJI, and had culture-confirmed MRSA from synovial or intra-articular tissue culture. PJIs were either treated with exchange arthroplasty or debridement with antibiotic and implant retention (DAIR). Success was defined as no further surgical treatment for infection at two years. Kaplan–Meier estimates were used to calculate the 2-year survival rate free from treatment failure. Univariate logistic regression was performed to identify risk factors associated with treatment failure.Results65 MRSA PJIs were identified with 42 undergoing explantation and 23 undergoing DAIR. Demographics, Charlson comorbidities, infection type (early post-operative, hematogenous or late chronic), and history of prior PJI were not significantly different between treatment groups. Survivorship at two years was 75% (95% confidence interval [CI] 61–88%) for exchange compared with 29% (95% CI 10–48%) for DAIR, P = 0.0002. Within the exchange group, knee PJIs were more likely to fail than hip PJI (odds ratio [OR] 7.1, CI 1.3–38, P = 0.02), and patients with diabetes were more likely to fail (OR 17, CI 1.6–178, P = 0.02).ConclusionMRSA PJIs treated with DAIR have worse outcomes than those treated with prosthesis exchange. Further investigation is needed to identify predictors of DAIR success, to optimize surgical treatment choice, and to improve outcomes of these difficult infections.

399. Treatment and Outcome of Prosthetic Joint Infection in Unicompartmental Knee Arthroplasty

BackgroundUnicompartmental knee arthroplasty (UKA) is an increasingly popular alternative to total knee replacement due to easier recovery and greater satisfaction. However, limited evidence guides the management of periprosthetic joint infection (PJI) in UKA specifically. We retrospectively reviewed the largest cohort of UKA PJI to date, providing our experience in a high volume tertiary institution.MethodsAn institutional PJI database was queried from 2008 to 2016 to identify all PJI cases with an index procedure of UKA. Treatment, diagnostic criteria, Charlson Comorbidity Index (CCI) and microbiology data were collected. Success was defined as no further surgical treatment for infection at 2 years. A chi-square test or Fisher’s exact test was used for comparisons between treatment success and failure groups. Survival probability was calculated using the Kaplan–Meier method.ResultsA total of 24 UKA PJIs were identified with 22 meeting MSIS criteria. Median age at infection was 65.9 years (range, 50.8–87.4), median BMI was 26.7 kg/m2 (range, 21.2–49.5), 75% male (18/24).The average follow-up time was 2.83 years. 9 patients presented with early (4 weeks of symptoms). 63% (15/24) of PJI cases were staphylococcal and 8.3% (2/24) were culture negative. Patients were either treated with 1 stage exchange (n = 3, 100% success), two-stage exchange (n = 5, 80% success) or implant retention (n = 16, 75% success). Overall survivorship was 79% at 2 years (95% confidence interval [CI], 63%–95%). Overall there was no significant association between success and CCI (P = 0.46), infection type (P = 0.29), surgical therapy (P = 0.62), and microorganism (P = 0.05).ConclusionIn this series, UKA PJIs tended to present more often as early post-operative or hematogenous infections. We observed no significant benefit with revision surgery and therefore conclude that implant retention should be considered as first-line surgical treatment. Outcomes of UKA PJI appear comparable to those in TKA PJIs.Disclosures All authors: No reported disclosures.

The Bacteriological Profile of Surgical Site Infections in Orthopaedic Implant Surgeries in South-East Nigeria

Background: Knowledge of the common bacteria that cause surgical site infection (SSI) and their antibiotic sensitivity is mandatory if treatment of surgical infection is to be successful. The threat of the emergence of resistant strains of bacteria is ever-present. Hence, a sensitivity directed therapy is paramount for the successful eradication of organisms with minimal risk of development of antibiotic resistance. Aim: The aim is to identify the common bacteria that cause SSI in orthopaedic implant surgeries in our hospital. Method: This is a prospective longitudinal study that includes all orthopaedic surgeries involving the use of implants within one year. Patients that had major orthopaedic surgeries involving implant were followed up and their wounds inspected for signs of SSI on postoperative days 3, 7, 14, 42 and 90. Wound swab was taken for microscopy, culture and sensitivity analysis from those who had wound infection, based on the CDC guidelines. Results: One-hundred and sixteen patients met our inclusion criteria and were included in the analysis. There were 62 males and 54 females. The mean age of the participant was 39.62 years (SD = 15.02 years). Fracture fixation with plates and screws was the most common implant surgery done. The incidence of SSI was 2.6%, and Escherichia coli was the most common isolated pathogen. All the SSIs were superficial incisional type, and the infection was monomicrobial in 67% of cases and polymicrobial in 33%. All of the isolated pathogens were sensitive to Imipenem and Gentamycin. Conclusion: Superficial incisional SSI is the most common type of SSI in this study. Escherichia coli is the most frequent pathogen in SSI affecting implant surgeries in our hospital. Gentamycin and Imipenem should be used for the prophylaxis of SSI in our environment.

Antimicrobial Peptides.

Bacterial resistance to available antibiotics has resulted in enhanced efforts at antibiotic stewardship but also has led to investigation into alternative methods for managing surgical infections. Antimicrobial peptides (AMPs) are naturally occurring compounds produced by all prokaryotic and eukaryotic cells that have potential as an alternative to conventional antibiotics. The published literature was reviewed for investigations that were relevant to infections commonly seen by surgeons and the potential applicability of AMPs for surgical care. Antimicrobial peptides are low-molecular-weight peptides with activity against bacteria, fungi, and viruses. Experimental evidence shows that AMPs have activity against highly resistant bacteria identified from human infections. Furthermore, these peptides can be designed as semi-synthetic or totally synthetic constructs for potential clinical use. Antimicrobial peptides appear to have in vivo activity in limited animal studies, but the experimental models for evaluation of these peptides need more clinical relevance. These products are in clinical evaluation at present but are limited in number and are being evaluated primarily for topical applications. Antimicrobial peptides have considerable in vitro evidence that supports their use for the prevention and treatment of surgical infections. Better experimental and clinical trial efforts are needed to move this technology toward applicability in surgical care.

The surgical treatment of infection secondary to pancreatic and (or) peri-pancreatic necrosis

Several minimally invasive techniques were used to treat infection secondary to pancreatic and (or peri-pancreatic) necrosis recent years, including percutaneous catheter drainage (PCD), endoscopic transluminal treatment, min-incision surgery, video-assisted minimally invasive technique and laparoscopic surgery. We should grasp the indication of each technique. PCD/ endoscopic transluminal surgery usually acted as initial therapy. Open surgery is still effective, and acts as a rescue operation when minimally invasive techniques fail. Key words: Acute pancreatitis; Necrosis; Infection; Minimally invasive treatment; Percutaneous catheter drainage (PCD); Endoscopic transluminal drainage (ETD)

Сравнительные аспекты бактериологической диагностики, течения и результатов лечения впервые выявленного туберкулеза, изолированного и при его сочетании с хронической обструктивной болезнью легких

Despite the use of modern methods of diagnostics and treatment of surgical infections, there is a steady tendency to the increase in severe complications after acute odontogenic infections (abscesses, sepsis, mediastinitis, and secondary intracranial complications). Sepsis associated with purulent-inflammatory processes of the maxillofacial area mainly develops in the presence of background pathology (68.4%). Patients without background disease (64.8% and 83.9%, respectively) predominate in the group of patients with systemic inflammatory response syndrome and local forms of purulent infections. The most common background pathology involves the respiratory and cardiovascular systems (60%), and rarely - diabetes mellitus, mainly of the second type (about 20%). The background diseases of the digestive system include chronic viral and toxic hepatitis, the disease of operated stomach, alcoholic disease. Isolated cases are those of chronic renal failure requiring hemodialysis (2.4 percent).
