Do preoperative glucose levels predict risk of complications in orthopaedic surgery?

Post-operative hyperglycemia is a known risk factor for post-surgical complications. The predictive value of pre-operative blood glucose levels, however, is less understood. This study aimed to determine if pre-operative screening blood glucose levels affect the rate of post-operative infection or wound complications. We also investigated if case urgency or anatomic location alters this relationship. A single-institution retrospective chart review was performed to evaluate patients treated between 2018 and 2021. Subjects ≥ 18years with closed, non-infected orthopaedic diagnoses requiring surgery were included. Case urgency, demographics, comorbidities, blood glucose level within twelve h prior to surgery, and hemoglobin A1c level within 3months of surgery, were collected. Infections and wound complications were recorded as outcomes. A total of 775 subjects with a mean age of 61 (range 18-96) were identified, including 543 elective and 232 trauma patients, with a mean pre-operative fasting glucose value of 127.7mg/dL (range, 49-388mg/dL) and average HbA1c of 6.9%. The odds of infectious complications were increased by a factor of 1.01 for every 1-point increase in blood glucose (95% CI 1.01-1.02; p < 0.01). Pre-operative blood glucose levels greater than 137mg/dL were associated with an increase in wound complications, but not deep infections. Infection rates stratified by anatomic site and case urgency were not impacted by pre-operative glucose levels. The increased risk of poor wound healing in patients with pre-operative hyperglycemia demonstrates that day of surgery point-of-care blood glucose screening can be a useful risk stratification tool.

A systematic review comparing different approaches for inflatable penile prosthesis revision: partial-component exchange, complete-component exchange, or reservoir "drain and retain".

In cases of a noninfected malfunctioning inflatable penile prosthesis (IPP) device, surgeons often opt to exchange all of the device rather than the defective component for fear of an increased infection rate and future mechanical dysfunction. To assess whether partial-component exchange of an IPP device has comparable outcomes to complete explant and replacement of an IPP device with or without a retained reservoir. A systematic review was conducted following the PRISMA 2020 and AMSTAR guidelines. Searches were performed on MEDLINE (Ovid), PubMed, and the Cochrane Library from inception to June 2023, identifying studies reporting outcomes and complications of revision surgery for noninfected malfunctioning IPP devices. Three groups were compared: those undergoing single- or 2-component exchange, those with complete explantation and replacement, and those with replacement of all components while retaining the primary reservoir. Analysis included 11 articles comprising 12 202 patients with complete device replacement, 234 with partial device exchange, and 151 with retained reservoirs following revision. Mean ages ranged from 62 to 68 years, with median follow-up times between 3 and 84 months. Partial-component exchange showed a higher infection rate (6.3%) as compared with complete replacement (2.7%) and reservoir retention (3.9%). Similarly, partial exchange had a higher complication rate (23.9%) when compared with complete replacement (11.3%) and reservoir retention (19.6%). Mechanical failure rates for partial exchange were similar across the 3 groups (10%, 2.8%, and 5.8%, respectively). Partial-component exchange during IPP revision is associated with higher infection and perioperative complication rates but comparable rates of mechanical failure as compared with complete-component replacement, with or without retaining the original reservoir.

#1487 Preoperative ultrasound vascular mapping as a predictor of arteriovenous fistula survival: a prospective cohort study

Abstract Background and Aims The morbidity and mortality of hemodialysis (HD) patients is directly related to the vascular access (VA) type. The arteriovenous fistula (AVF) is considered the VA of choice. When compared to the use of catheter, the use of AVF encompasses a lower infectious complications rate and a higher survival rate. The use of catheter has been independently associated with an increased risk of morbidity and mortality, especially during the first year of treatment. It is essential that HD programs maintain a high incidence and prevalence of AVF as a VA. For that reason, a multidisciplinary management is mandatory, with the collaboration of nephrologists, vascular surgeons, radiologists, and nurses. All patients who have an indication of AVF should have a prior ultrasound vascular mapping performed by the nephrologist to determine the most appropriate type of AVF. According to guidelines, there are several factors that increase the risk of AVF failure including advanced age, history of smoking, diabetes mellitus and peripheral vascular disease, among others. Therefore, the aim of this study is to determine the benefits of performing a preoperative ultrasound vascular mapping in terms of AVF survival. The secondary objective is to associate some risk factors to a higher rate of AVF failure. Method We conducted a prospective cohort study between January 2020 and December 2023. The viability of AVF was compared between AVF resulting from a preoperative ultrasound vascular mapping and those AVF without previous mapping. A multivariate analysis was performed with the entire population to determine the factors related to AVF survival. Results This study analyzed a total of 136 AVF, both native and prosthetic. Our population included 106 patients, mostly men (69.79%), with a median age of 68 years old (IR: 56-76), and history of smoking in a 39.10%, of diabetes in a 42.43%, and of peripheral vascular disease in a 17.54%. A preoperative ultrasound vascular mapping was previously performed in 107 AVF (78.7%). A total of 93 AVF were functional (68.4%). Regarding the analyzed risk factors of AVF failure (including advanced age and history of smoking, diabetes mellitus and peripheral vascular disease, and elbow/wrist AVF), we observed that advanced age and elbow AVF were related to higher survival of the AVF (p = 0.048 and p = 0.01 respectively). In the multivariate analysis we observed that advanced age and elbow AVF were independent predictors of AVF survival (p = 0.038 and p = 0.001, respectively). When comparing the cohorts, in the AVFs were the preoperative vascular ultrasound was performed, 78 AVF were functional (72.9%). In the AVFs were no mapping was performed, 15 AVF were functional (51.7%). This difference was statistically significant (p = 0.03). This implies a 21.2% increase in the probability of AVF survival when performing our AVF mapping. Conclusions The performance of a preoperative ultrasound vascular mapping by the nephrologist in our population has been associated to a significant increase in AVF survival. For that reason, we consider that it is an indispensable tool for the creation and monitoring of VA. When analyzing risk factors classically associated to AVF failure, we found that advanced age and elbow AVF were independent predictors of higher AVF survival. Other risk factors, such as history of diabetes mellitus, smoking, and peripheral arterial disease, were not significantly related to AVF failure in our population.

Donor Site Outcomes Following Autologous Breast Reconstruction with DIEP Flap: A Retrospective and Prospective Study in a Single Institution

Background: The deep inferior epigastric perforator artery (DIEP) free flap is the most commonly performed autologous breast reconstruction. Despite the relative reduction in donor site complications compared to nonmuscle-sparing options, there is still high morbidity associated with this surgery. The purpose of this study is to compare outcomes and complications at our institution and to discuss potential quality improvement initiatives. Methods: A retrospective cohort study was performed looking at patients who underwent delayed or immediate autologous breast reconstruction with a DIEP flap over a 6-year period (2015-2021) at our institution. Complication rates for abdominal infection, seroma, hematoma, wound dehiscence, delayed wound healing, umbilical necrosis, subjective abdominal weakness, abdominal bulge, and hernia were calculated. Additionally, a prospective cohort study was conducted using a portable ultrasound device to detect postoperative changes in the abdominal donor site, including fluid collections and postoperative edema. Results: One hundred seventeen patients underwent autologous breast reconstruction with a DIEP-free flap. Forty-one percent of patients experienced 1 or more donor site complications. Complication rates were 16.2%, 12.8%, 1.7%, 15.4%, 8.5%, 4.3%, 0%, 10.3%, and 2.6%, respectively, for the list above. There was a higher proportion of complications in patients who smoked within the past 3 months and those who had a body mass index (BMI) between 35 and 39.9, although this was not statistically significant. Bilateral reconstructions had higher rates of umbilical necrosis (24.5% vs 7.8%) and wound dehiscence (9.4% vs 0%) compared to unilateral. Twenty-one patients were included in the prospective analysis. No significant changes in abdominal wall edema were found. Twenty-four percent of the patients had detectible collections on ultrasound, and these were associated with wound dehiscence and the need for debridement. Discussion: Our institutional abdominal donor site complication rates in DIEP reconstruction patients are higher than those published in the literature. Similar complication rates were identified regardless of smoking status, BMI, and unilateral/bilateral surgery. Quality improvement initiatives could be considered and implemented to reduce future complications.

Do alpha blockers reduce the risk of urinary retention post-transperineal prostate biopsy? A systematic narrative review.

Transperineal Prostate Biopsy (TPB) is a commonly used technique for the diagnosis of prostate cancer due to growing concerns related to infectious complications associated with transrectal ultrasound-guided prostate biopsy (TRUSB). TPB is associated with an infective complication rate of near zero, however, acute urinary retention (AUR) remains the leading complication causing morbidity. Previously in TRUSB, there was weak evidence that alpha-blockers reduce AUR rates, and their usage has been extrapolated to clinical practice with TPB. This review aims to explore if there is an evidence base for using alpha-blockers to prevent AUR following TPB. A systematic approach was used to search Ovid Medline and Embase using keywords related to "Transperineal" and "Retention". Articles were then screened by applying inclusion and exclusion criteria to find studies that compared alpha-blocker recipients to no alpha-blocker use in the perioperative period and the subsequent effect on AUR in TPB. 361 records were identified in the initial search to produce 5 studies included in the final review. No randomised controlled trials (RCTs) were identified. One observational study showed a reduction in AUR rate from 12.5% to 5.3% with a single dose of tamsulosin. A previous systematic review of complications associated with prostate biopsy concluded there may be a potential benefit to alpha-blockers given in the TPB perioperative period. Three observational studies demonstrated a harmful effect related to alpha-blocker use; however, this was well explained by their clear limitations. Based on this review and the extrapolation from TRUSB data, perioperative alpha-blockers may offer some weak benefits in preventing AUR following TPB. However, there is significant scope and need for an RCT to further develop the evidence base further given the significant gap in the literature and lack of a standard alpha blocker protocol in TPB.

Frequency of Mortality and Adverse Outcomes of COVID-19 in Hospitalized Type 2 Diabetics with a History of Sitagliptin or Metformin Use

Background: The relationship between various blood glucose-lowering treatments for type 2 diabetes mellitus (T2DM) and the mortality and complication rates of COVID-19 infection holds significant relevance. Objectives: This retrospective study aimed to investigate the clinical progression of COVID-19 in T2DM patients previously treated with sitagliptin, metformin, or a combination of both. Methods: The study reviewed the medical records of T2DM patients with COVID-19 who had received treatment with sitagliptin, metformin, or both. Participants were selected from those admitted to Naft Hospital in Ahvaz, Iran, from March 2020 to March 2022. Data on mortality and adverse outcomes related to COVID-19 were gathered from the medical records. Results: The study included 529 diabetic patients treated with metformin (n = 197), sitagliptin (n = 231), or both (n = 101) for a minimum of three months. The overall mortality rate among diabetic patients was 15.1%, with the metformin group showing the highest mortality rate at 28.9% (P &lt; 0.0001). Significant differences were observed among the three treatment groups in terms of the frequency of acute respiratory failure (P &lt; 0.0001), stroke (P = 0.002), pulmonary embolism (P &lt; 0.0001), and the necessity for ICU admission (P &lt; 0.0001). Nonetheless, the incidence of myocardial infarction did not significantly differ between the groups. Conclusions: The findings suggest that sitagliptin use for blood sugar control in T2DM patients may help reduce adverse outcomes and the risk of death due to COVID-19. Mortality and morbidity rates were found to be higher in patients treated with metformin compared to those in the other groups.

After Primary Shoulder Arthroplasty Appropriate Vancomycin Antibiotic Prophylaxis Does Not Lead to Increased Infectious Complications When Compared to Cefazolin

INTRODUCTIONIn primary shoulder arthroplasty (SA), intravenous (IV) cefazolin has demonstrated lower rates of infectious complications when compared to IV vancomycin. However, previous analyses included SA cohorts with both complete and incomplete vancomycin administration. Therefore, it is currently unclear whether cefazolin still maintains a prophylactic advantage to vancomycin when it is appropriately indicated and sufficiently administered at the time of surgical incision. This study evaluated the comparative efficacy of cefazolin and complete vancomycin administration for surgical prophylaxis in primary shoulder arthroplasty with respect to infectious complications. METHODSA retrospective cohort study was conducted utilizing a single institution total joint registry database, where all primary SA types (hemiarthroplasty, anatomic total shoulder arthroplasty, reverse shoulder arthroplasty) performed between 2000 to 2019 for elective and trauma indications using IV cefazolin or complete vancomycin administration as the primary antibiotic prophylaxis were identified. Vancomycin was primarily indicated for patients with a severe self-reported penicillin or cephalosporin allergy and/or MRSA colonization. Complete administration was defined as at least 30 minutes of antibiotic infusion prior to incision. All included SA had at least 2 years of clinical follow-up. Multivariable Cox proportional hazard regression was used to evaluate all-cause infectious complications including survival free of prosthetic joint infection (PJI). RESULTSThe final cohort included 7,177 primary SA, 6,879 (95.8%) received IV cefazolin and 298 (4.2%) received complete vancomycin administration. Infectious complications occurred in 120 (1.7%) SA leading to 81 (1.1%) infectious reoperations. Of the infectious complications 41 (0.6%) were superficial infections and 79 were (1.1%) PJIs. When categorized by administered antibiotics, there were no differences in rates of all infectious complications (1.6% vs. 2.3%; P = .352), superficial complications (0.5% vs. 1.3%; P = .071), PJI (1.1% vs. 1.0%; P = .874), or infectious reoperations (1.1% vs. 1.0%; P = .839). On multivariable analyses, complete vancomycin infusion demonstrated no difference in rates of infectious complications compared to cefazolin administration (hazard ratio [HR], 1.50 [95% confidence interval (CI), 0.70 to 3.25]; P = .297), even when other independent predictors of PJI (male sex, prior surgery, and Methicillin-resistant Staphylococcus aureus colonization) were considered. CONCLUSIONSIn comparison to cefazolin, complete administration of vancomycin (infusion to incision time greater than 30 minutes) as the primary prophylactic agent does not adversely increase the rates of infectious complications and PJI. Prophylaxis protocols should promote appropriate indications for the use of cefazolin or vancomycin, and when necessary, ensure complete administration of vancomycin to mitigate additional infectious risks after primary SA.

Trends in Elbow Ulnar Collateral Ligament Repairs and Reconstructions and an Analysis Between Low- and High-Volume Surgical Centers: A 10-Year Study in New York State.

Elbow ulnar collateral ligament (UCL) reconstruction (UCLR) is the gold standard for operative treatment of UCL tears, with renewed interest in UCL repairs. To (1) assess trends in rates of UCLR and UCL repair and (2) identify predictors of complications by demographic, socioeconomic, or surgical center volume factors. Descriptive epidemiology study. Patients who underwent UCLR or UCL repair at New York State health care facilities between 2010 and 2019 were retrospectively identified; concomitant ulnar nerve procedures among the cohort were also identified. Surgical center volumes were classified as low (<99th percentile) or high (≥99th percentile). Patient information, neighborhood socioeconomic status quantified using the Area Deprivation Index, and complications within 90 days were recorded. Poisson regression analysis was used to compare trends in UCLR versus UCL repair. Multivariable regression was used to determine whether center volume, demographic, or socioeconomic variables were independent predictors of complications. A total of 1448 UCL surgeries were performed, with 388 (26.8%) concomitant ulnar nerve procedures. UCLR (1084 procedures; 74.9%) was performed more commonly than UCL repair (364 procedures; 25.1%), with patients undergoing UCL repair more likely to be older, female, and not privately ensured and having undergone a concomitant ulnar nerve procedure (all P < .001). With each year, there was an increased incidence rate ratio for UCL repair versus UCLR (β = 1.12 [95% CI, 1.02-1.23]; P = .022). The authors identified 2 high-volume centers (720 UCL procedures; 49.7%) and 131 low-volume centers (728 UCL procedures; 50.3%). Patients undergoing UCL procedures at high-volume centers were more likely to be younger and male and receive workers' compensation (all P < .001). UCL repair and ulnar nerve-related procedures were both more commonly performed at low-volume centers (P < .001). There were no significant differences in 3-month infection, ulnar neuritis, instability, arthrofibrosis, heterotopic ossification, or all-cause complication rates between low- and high-volume centers. The only significant predictor for all-cause complication was Medicaid insurance (OR, 2.91 [95% CI, 1.20-6.33]; P = .011). A rising incidence of UCL repair compared with UCLR was found in New York State, especially among female patients, older patients, and nonprivate payers. There were no differences in 3-month complication rates between high- and low-volume centers, and Medicaid insurance status was a predictor for overall complications within 90 days of operation.

Risk factors of early infectious complications after ureterorenoscopy for stone disease: a prospective study.

To prospectively evaluate the rate and associated risk factors of early infectious complications after ureterorenoscopy for urolithiasis. After ethical committee approval, 400 therapeutic retrograde ureterorenoscopy procedures between August 3, 2020 and November 24, 2021 were included for analysis in a single-center study. Postoperative infection was defined as an afebrile urinary tract infection, fever (≥ 38°C) with pyuria (≥ 300WBC/μL) or proven urinary pathogen, and urosepsis. The primary outcome was the rate of infectious complications after ureterorenoscopy. Secondary outcomes were the perioperative factors that increased the risk of infectious complications within 30days of surgery using univariate and multivariate logistic regression analysis. Twenty-nine of four hundred (7.3%) patients developed an infectious complication within 30days after ureterorenoscopy. Ten (2.5%) patients developed an afebrile urinary tract infection, eight (2.0%) developed fever with pyuria, five (1.3%) febrile urinary tract infection, and six (1.5%) urosepsis. On univariate analysis, preoperative stent-type JFil® pigtail suture stent was significantly associated with the dependent variable (p < 0.001). On multivariate logistic regression analysis, older age (OR 1.035; 95% CI 1.006-1.070; p = 0.02) was found to be significantly associated with developing a postoperative infectious complication. A 7.3% rate of postoperative infectious complications and 1.5% urosepsis rate were observed after therapeutic ureterorenoscopy, without the need of intensive care admission. The only significant risk factors were preoperative stent type (JFil® pigtail suture stent) on univariate analysis, and older age on multivariate logistic regression analysis. Further multicentric prospective observational data are needed in this field.

Assessment of Effectiveness and Safety of Aspiration-Assisted Nephrostomic Access Sheaths in PCNL and Intrarenal Pressures Evaluation: A Systematic Review of the Literature.

Background: Different suction-assisted nephrostomic sheaths have been developed for percutaneous nephrolithotomy (PCNL). Objectives: (1) To examine PCNL techniques performed with different aspiration-assisted sheaths (Clear Petra® sheath, Superperc, SuperminiPCNL, and a miniPCNL patented sheath), with specific regard to effectiveness and safety outcomes in adult and paediatric patients; (2) to extrapolate intrarenal pressure (IRP) data during these procedures. Methods: A systematic literature search was performed in accordance with PRISMA guidelines. Relevant articles up to 8 February 2024 were included. Results: Twenty-five studies were selected, thirteen retrospective and twelve prospective. The use of four different aspirating sheaths for miniPCNL was reported: Clear Petra® sheath, Superperc, SuperminiPCNL, and a miniPCNL patented sheath. Stone free rates (SFRs) across techniques ranged from 71.3% to 100%, and complication rates from 1.5% to 38.9%. Infectious complication rates varied from 0 to 27.8% and bleeding complication rates from 0 to 8.9%. Most complications were low grade ones. The trend among studies comparing aspiration- and non-aspiration-assisted miniPCNL was towards equivalent or better SFRs and lower overall infectious and bleeding complication rates in suction techniques. Operation time was consistently lower in suction procedures, with a mean shortening of the procedural time of 19 min. Seven studies reported IRP values during suction miniPCNL. Two studies reported satisfactory SFRs and adequate safety profiles in paediatric patient cohorts. Conclusions: MiniPCNL with aspirating sheaths appears to be safe and effective in both adult and paediatric patients. A trend towards a reduction of overall infectious and bleeding complications with respect to non-suction procedures is evident, with comparable or better SFRs and consistently shorter operative times. The IRP profile seems to be safe with the aid of aspirating sheaths. However, high quality evidence on this topic is still lacking.

Infection risk reduction with povidone-iodine rectal disinfection prior to transrectal prostate biopsy: an updated systematic review and meta-analysis

BackgroundTo prevent infectious complications after transrectal ultrasound-guided prostate biopsy (TRUS-PB), some studies have investigated the efficacy of rectal disinfection using povidone-iodine (PI) and antibiotic prophylaxis (AP).ObjectiveTo summarize available data and compare the efficacy of rectal disinfection using PI with non-PI methods prior to TRUS-PB.Evidence acquisitionThree databases were queried through November 2023 for randomized controlled trials (RCTs) analyzing patients who underwent TRUS-PB. We compared the effectiveness of rectal disinfection between PI groups and non-PI groups with or without AP. The primary outcomes of interest were the rates of overall infectious complications, fever, and sepsis. Subgroups analyses were conducted to assess the differential outcomes in patients using fluoroquinolone groups compared to those using other antibiotics groups.Evidence synthesisWe included ten RCTs in the meta-analyses. The overall rates of infectious complications were significantly lower when rectal disinfection with PI was performed (RR 0.56, 95% CI 0.42–0.74, p < 0.001). Compared to AP monotherapy, the combination of AP and PI was associated with significantly lower risk of infectious complications (RR 0.54, 95% CI 0.40–0.73, p < 0.001) and fever (RR 0.47, 95% CI 0.30–0.75, p = 0.001), but not with sepsis (RR 0.49, 95% CI 0.23–1.04, p = 0.06). The use of fluoroquinolone antibiotics was associated with a lower risk of infectious complications and fever compared to non-FQ antibiotics.ConclusionRectal disinfection with PI significantly reduces the rates of infectious complications and fever in patients undergoing TRUS-PB. However, this approach does not show a significant impact on reducing the rate of sepsis following the procedure.

The Association Between Duration of Antibiotics and Infectious Complications Following Radical Cystectomy: Analysis of the 2019-2021 NSQIP Database

ObjectivesTo identify the impact of the duration of peri-operative antibiotics on infectious complications following radical cystectomy. MethodsThe National Surgical Quality Improvement Project (NSQIP) targeted database was queried for patients undergoing radical cystectomy from 2019-2021. Baseline patient characteristics were collected. Antibiotic duration was classified as <24 hours (short), 24-72 hours (intermediate) or >72 hours (long). Infectious complication data was collected including surgical site infection (SSI), urinary tract infection (UTI), organ space infection, pneumonia, sepsis, and clostridium difficile infection up to 30 days after surgery. Univariate and multivariable analyses were performed to compare duration of antibiotic therapy to infectious outcomes. ResultsOf the 4,363 patients who underwent radical cystectomy, 3,250(74%), 827(19%) and 286(6.6%) received short, intermediate, and long duration of peri-operative antibiotics respectively. Infectious complication occurred in 954(22%) patients, including 227(5.2%) SSI, 280(6.4%) UTI, 268(6.1%) organ space infection, 87(2%) pneumonia, and 378(8.7%) sepsis. Clostridium difficile infection occurred in 89(2%) patients. On multivariable analysis, there was no significant difference in overall infectious complication rates with long duration antibiotics. However, intermediate duration of antibiotics in open surgery was associated with a decreased risk of SSI (OR 0.58; 95%CI 0.37-0.91) compared to those treated with short term antibiotics. ConclusionsDespite guideline recommendations, 26% of patients in this database received >24 hours of peri-operative antibiotics without decreased risk of overall infectious complication. An intermediate course of antibiotics decreased risk of SSI in open surgery compared to the guideline recommend <24-hour course. Greater education regarding antibiotic stewardship and further studies investigating infectious complications are warranted.

Comparison of Complication Rates and Surgical Costs for Total Ankle Replacements Performed in the Outpatient vs Inpatient Setting

Introduction/Purpose: Increasing data has highlighted the safety and cost-effectiveness of outpatient hip, knee, and shoulder arthroplasty. However, limited evidence – mainly small, single institution case series – has explored complication rates and costs between outpatient and inpatient total ankle arthroplasty (TAA) surgeries. Methods: Utilizing Medicare claims from 2016 to 2019, we retrospectively identified patients ≥65 years of age who underwent TAA based on CPT coding. Patients on Medicare HMO, under age 65, and dual-eligible patients were excluded. Within this dataset, we compared surgeries performed in the outpatient versus inpatient setting. We compared groups based on readmission, all-complication, and infection rates within 1-year of TAA using logistic regressions controlling for age, sex, race, and comorbidity. To help mitigate bias, we also performed a propensity matched model with the same variables. Data were reported as percentage point (PPT) differences (95% CI) between groups, with a positive number indicating higher complication rates and costs among patients treated in the inpatient setting. Results: In total, 8,281 total ankle arthroplasty cases were identified (outpatient: 5,524 and inpatient: 2,757. Compared to inpatient cases, outpatient TAA surgeries were performed on younger, healthier (as assessed by Charlson Comorbidity Index (CCI) scores) patients who were more likely to be female (p &lt; 0.001). In logistic regression analyses, outpatient TAA cases had lower readmission, all-complication, infection, mortality, and device-associated complication rates (p &lt; 0.001) as compared to inpatient surgeries. Further, outpatient surgeries had sizable cost reductions compared to inpatient surgeries (p &lt; 0.001). Conclusion: TAA performed in the outpatient setting appears to have less complications and decreased cost compared to inpatient procedures – though inpatient surgeries were presumably riskier as they were performed on older patients with increased co-morbidities. When clinically appropriate, though, TAA as an outpatient procedure appears to provide substantial reductions in cost with notable reductions in surgical risk.

Eyeing Risks: A Critical Analysis of the Use of Periorbital Steroids in Fronto-orbital Advancement.

To evaluate the outcomes associated with two techniques of periorbital steroid administration in bilateral fronto-orbital advancement (FOA). Multi-institutional retrospective chart review. Two high volume, tertiary US craniofacial centers. Patients who underwent FOA between 2012 and 2021. Patients were divided into three cohorts based on method of steroid administration. Groups GEL and INJ represent those who received steroids in the form of triamcinolone soaked gelfoam or direct injection of dilute triamcinolone to the frontal/periorbital region, respectively. Group NON did not receive any periorbital steroids. Peri-operative outcomes including hospital length of stay and complications were evaluated based on method of periorbital steroid administration. Variables predictive of infectious complications were assessed using stepwise logistic regression. Four hundred and twelve patients were included in our sample (INJ:249, GEL:87, NON:76). Patients in the INJ group had a higher ASA class (P < .001) while patients in the NON group were significantly more likely to be syndromic (P < .001) and have multisuture craniosynostosis (P < .001). Rate of infectious complications for each cohort were NON: 2.6%, INJ: 4.4%, and GEL: 10.3%. There was no significant difference between groups in hospital length of stay (P = .654) or rate of post-operative infectious complications (P = .061). Increased ASA class (P = .021), increased length of stay (P = .016), and increased intraoperative narcotics (P = .011) were independent predictors of infectious complications. We identified a dose-dependent relationship between periorbital steroids and rate of postoperative infections, with key contributions from ASA class, hospital length of stay, and dose of intraoperative narcotics.

Vacuum-assisted mini-percutaneous nephrolithotomy is associated with lower rates of infectious complications compared to vacuum-cleaner procedure in patients at high risk for infections: a single-center experience

PurposeTo evaluate the impact of vacuum-assisted mini-percutaneous nephrolithotomy (vamPCNL) vs. vacuum-cleaner mPCNL (vcmPCNL) on the rate of postoperative infectious complications in a cohort of patients with high risk factors for infections.MethodsWe retrospectively analysed data from 145 patients who underwent mPCNL between 01/2016 and 12/2022. Patient’s demographics, stones characteristics and operative data were collected. vamPCNL and vcmPCNL were performed based on the surgeon’s preference. High-risk patients were defied as having ≥ 2 predisposing factors for infections such as a history of previous urinary tract infections, positive urine culture before surgery, stone diameter ≥ 3 cm, diabetes mellitus and hydronephrosis. Complications were graded according to modified Clavien classification. Descriptive statistics and logistic regression models were used to identify factors associated with postoperative infectious complications.ResultsvamPCNL and vcmPCNL were performed in 94 (64.8%) and 51 (35.2%) cases, respectively. After surgery, infectious complications occurred in 43 (29.7%) participants. Patients who developed infectious complications had larger stone volume (p = 0.02) and higher rate of multiple stones (p = 0.01) than those who did not. Infectious complications occurred more frequently after vcmPCNL than vamPCNL (55.9% vs. 44.1%. p = 0.01) in high-risk patients. Longer operative time (p < 0.01) and length of stay (p < 0.01) were observed in cases with infectious complications. At multivariable logistic regression analysis, longer operative time (OR 1.1, p = 0.02) and vcmPCNL (OR 3.1, p = 0.03) procedures were independently associated with the risk of infectious complications post mPCNL, after accounting for stone volume.ConclusionOne out of three high-risk patients showed infectious complications after mPCNL. vamPCL and shorter operative time were independent protective factors for infections after surgery.

Nomogram for Predicting Infectious Complications Following Curative Gastrectomy Using Clinical and Laboratory Parameters.

Postoperative infectious complications are prevalent and significantly impact the prognosis and hospital stay duration after curative gastrectomy. This study aimed to identify predictive factors and develop a nomogram for predicting infectious complications prior to patient discharge. Between April 2019 and December 2023, clinicopathological data of 237 patients with gastric cancer who underwent curative gastrectomy at the Eunpyeong St. Mary's Hospital were retrospectively reviewed. C-reactive protein (CRP), white blood cell (WBC) count, neutrophil-lymphocyte ratio (NLR), and procalcitonin (PCT) levels were analyzed. Overall, 58 patients experienced postoperative complications, with 33 patients developing infectious complications. Univariate analysis revealed that the open approach, esophagus involving resection, advanced stage, and operation time were risk factors for infectious complications among clinicopathologic characteristics. Significant associations with laboratory parameters and body temperature (BT) were observed from postoperative day (POD) 1 to 5, with the highest area under the curve (AUC) observed for POD 5 data in receiver operating characteristic (ROC) analysis. Multivariate analysis incorporating clinicopathologic features and laboratory parameters on POD 5 identified age (OR=2.98), approach (OR=4.05), operation time (OR=2.74), WBC count (OR=4.09), NLR (OR=9.74), and CRP (OR=2.62) as selected factors. The developed nomogram stratified patients into low-risk (<10%), intermediate-risk (10~50%), and high-risk (≥50%) groups, corresponding to actual infectious complication rates of 1.84%, 28.3%, and 71.43%, respectively. This study presents a novel estimating model for infectious complications following curative gastrectomy. The utilization of this model in patient discharge planning can aid in identifying individuals who require additional treatment, thereby minimizing unexpected readmissions.

Antimicrobial prophylaxis protocol based on rectal swab culture before prostate biopsy to prevent infectious complications: a prospective randomized comparative study.

To evaluate the benefit of targeted antibiotic prophylaxis (TAP) based on rectal swab culture in comparison with standard empiric antimicrobial prophylaxis in patients undergoing transrectal ultrasound-guided needle biopsy of the prostate (TRUS-BP), as well as to assess rate of fecal carriage of Fluoroquinolone-resistant Enterobacterales FQRE. We prospectively analyzed data that randomized 157 patients within two groups: (G1) TAP according to rectal swab performed 10days before PB; (G2): empirical antibiotic prophylaxis with ciprofloxacin. Prevalence of FQRE digestive carriage and risk factors were investigated. Incidence of infectious complications after (TRUS-BP) in each group was compared. G2 included 80 patients versus 77 in G1. There was no difference between the two groups regarding age, diabetes, prostate volume, PSA, number of biopsy cores, and risk factors for FQRE. In G2, the prevalence of FQRE digestive carriage was 56.3% all related to E. coli species. In the case of digestive carriage of FQRE, TAP according to the rectal swab culture with third-generation cephalosporins was performed in 73.3%. Patients with FQRE had history of FQ use within the last 6months in 17.8% (p = 0.03). Rate of febrile urinary tract infection after PB was 13% in G1 and 3.8% in G2 (p = 0.02). Incidence of FQ resistance in the intestinal flora of our local population was prevalent. Risk factor for resistance was the use of FQ within the last 6months. TAP adapted to rectal swab, mainly with third-generation cephalosporins, significantly reduced the rate of infectious complications after (TRUS-BP).

Risk factors for shunt-dependent hydrocephalus after spontaneous subarachnoid hemorrhage

IntroductionSubarachnoid hemorrhage (SAH) is one of the most frequent neurosurgical emergencies, most of them due to intracranial aneurysm rupture. Hydrocephalus is a prevalent complication with a high rate of complications. The aims of this study are to identify predictors of shunt-dependent hydrocephalus following aneurysmal SAH and to quantify the complications arising from ventriculoperitoneal shunts. MethodsThis study is about an observational retrospective analytic study of the patients with spontaneous SAH admitted to Miguel Servet Universitary Hospital between 2017 and 2022. Patients’ clinical and radiological characteristics, type of treatment, diagnoses and treatment of hydrocephalus, complications of ventriculoperitoneal shunts and mortality are some of the data achieved in this study. A descriptive study of these variables has been done and, subsequently, the most relevant variables have been statistically analyzed to identify patients with increasing risk of shunting for hydrocephalus. This study was authorized by the Ethics Committee prior to its elaboration. ResultsA total of 359 patients with spontaneous SAH were admitted to Miguel Servet Universitary Hospital between 2017 and 2022, with an intrahospitalary death rate of 25,3%. 66,3% of the total of patients with SAH were due to intracranial aneurysm rupture (n = 238). 45,3% of the patients with aneurysmal SAH required an external ventricular drain (EVD) to treat acute hydrocephalus. 11,7% (n = 28) developed a shunt-dependent hydrocephalus. Statistical significance was found between shunt-dependent hydrocephalus and the following: high score in modified Fisher scale and placement of EVD. The mean interval from EVD to ventriculoperitoneal shunt placement was 26,1 days. The mean rate of reoperation of patients after shunt was 17,7%, mostly due to infection. ConclusionsThe most significant risk factor for shunt-dependent hydrocephalus after aneurysmal SAH was high Fisher grade and previous need of EVD. Shunt infections is the main cause of shunt reoperation. Early shunt placement in selected patients might reduce the rate of infectious complications.

Atrial Fibrillation Catheter Ablation among Cancer Patients: Utilization Trends and In-Hospital Outcomes.

Background: Atrial fibrillation (AF) catheter ablation in cancer patients has been evaluated in very few studies. We aimed to investigate utilization trends and in-hospital outcomes of AF catheter ablation among cancer patients in a large US inpatient registry. Methods: Utilizing the National Inpatient Sample (NIS) database, patients who underwent AF catheter ablation between 2012 and 2019 were identified. Sociodemographic, clinical data, in-hospital procedures and outcomes were collected. Baseline characteristics and in-hospital outcomes were compared between patients with and without cancer. Results: An estimated total of 67,915 patients underwent AF catheter ablation between 2012 and 2019 in the US. Of them, 950 (1.4%) had a cancer diagnosis. Patients with a cancer diagnosis were older and had higher Charlson Comorbidity Index, CHA2DS2-VASc and ATRIA bleeding indices scores. A higher rate of total complications was observed in cancer patients (10.5% vs. 7.9, p < 0.001), driven mainly by more bleeding and infectious complications. However, no significant differences in cardiac or neurological complications as well as in-hospital mortality rates were observed and were relatively low in both groups. Conclusions: AF catheter ablation in cancer patients is associated with higher bleeding and infectious complication rates, but not with increased cardiac complications or in-hospital mortality in a US nationwide, all-comer registry.

Confirmation of negative urine culture status after appropriate antibiotic treatment prior to endourological stone procedures: Is it really necessary?

To evaluate the necessity of confirmation for a negative urine culture test outcome after an appropriate antibiotic regimen for urinary tract infection (UTI) prior to endoscopic stone removal procedures. 170 cases receiving an appropriate antibiotic treatment for culture proven UTI based on test outcomes before endoscopic stone removal were evaluated in two groups: Group 1 (n = 85) Patients in whom a second urine culture test was performed to ensure “negative urine culture” status prior to the procedures after receiving antibiotic therapy and Group 2 (n = 85). Patients receiving the same antibiotic therapy without any additional urine culture test before the procedures. Cases were comparatively evaluated with respect to the statistical significance of post-operative infective complications (fever, sepsis), duration of hospital stay and readmission rates during early post-operative period. Our findings demonstrated no significant difference regarding the rate of infective complications (presence of fever, incidence of septic findings), hospitalization period and readmission rates between the two groups. Although the presence of a negative urine status has been confirmed by urine culture test in group 1 cases, no additional urine culture test was performed with this aim in group 2 cases (negative urine culture was confirmed only with urinalysis) and the outcomes regarding the infective problems were found to be similiar. Our current findings indicate that a second urine culture test may not be a “must” if the patients receive an appropriate antibiotic regimen based on the sensitivity test outcomes for a reasonable time period.
