Is it worth using the Comprehensive Complication Index over the Clavien-Dindo classification in elderly patients who underwent percutaneous nephrolithotomy?

To compare the Comprehensive Complication Index (CCI) to the Clavien-Dindo classification (CDC) in an elderly population who underwent percutaneous nephrolithotomy (PCNL) and to identify predictors of postoperative complications in this population. We conducted a retrospective cohort study involving patients 60years and older who underwent PCNL at our Institution between 2009 and 2020. Postoperative complications were considered up to 30days after surgery. Both CDC and CCI were calculated to assess patient outcomes. Length of stay (LOS) and admission to the emergency room (ER) were used as surrogates of postoperative complications. We included 244 patients with a median age of 65 [63-69] years. 15.6% presented postoperative complications, and 2.5% multiple complications. LOS had a correlation coefficient of 0.29 (p < 0.001) and ER admissions had a coefficient of 0.27 (p < 0.001) with both CDC and CCI. Cost of hospitalization based on CDC underestimated CCI-based cost of hospitalization in 0.8% (p = 0.049). Higher American Society of Anesthesiology (ASA) physical status (p = 0.02), Charlson Comorbidity Index (p = 0.008), Guy's classification (p = 0.005), and history of urinary tract infection (UTI, p = 0.047) exhibited significant correlations with postoperative complications. Both CDC and CCI equally correlate with LOS and ER admissions following PCNL in elderly patients. However, CDC underestimates cost of hospitalization in comparison to CCI. We found higher ASA physical status, Charlson Comorbidity Index, Guy's classification, and history of UTI as predictors of postoperative complications after this procedure in this population.

Meta-analysis and systematic review of factors predicting conversion to radical nephrectomy following robotic-assisted partial nephrectomy in renal cancer patients.

Evaluating the risk factors for the conversion from robotic-assisted partial nephrectomy (RAPN) to radical nephrectomy (RN). Through a comprehensive database search encompassing PubMed, Web of Science, Embase, and the Cochrane Library, we identified pertinent English-language research published by June 2024. We utilized the NOS scale for quality assessment. The aggregate effect was quantified via the odds ratio (OR), alongside a 95% confidence interval (CI). Sensitivity analyses were conducted using both fixed-effects and random-effects models to evaluate reliability. The meta-analytical process was facilitated by the Stata 18 software suite. Our meta-analysis encompassed a total of 8 retrospective studies and 3 prospective studies, totaling 4056 patients. We found that increasing patient age (OR: 1.04; 95% CI 1.00-1.08; P = 0.005), higher American Society of Anesthesiologists (ASA) scores (3 or above) (OR: 2.74; 95% CI 1.52-4.93; P = 0.001), elevated R.E.N.A.L. scores (7 or above) (OR: 2.49; 95% CI 1.57-3.95; P < 0.001), and the use of off-clamp RAPN (OR: 7.21; 95% CI 2.60-19.93; P < 0.001) significantly raised the odds of surgical conversion. On the other hand, male sex (OR: 1.04; 95% CI 0.67-1.62; P = 0.858), the side of the tumor (OR: 0.97; 95% CI 0.48-1.95; P = 0.936), tumor size (OR: 3.43; 95% CI 0.57-20.55; P = 0.177), body mass index (BMI) (OR: 1.03; 95% CI 0.96-1.11; P = 0.426), clinical stage (OR: 3.78; 95% CI 0.46-30.70; P = 0.214), and the use of single-port RAPN (OR: 0.54; 95% CI 0.16-1.78; P = 0.31) did not show a statistically significant link to an increased conversion risk. This meta-analysis elucidates the critical risk factors for the conversion from robotic-assisted partial nephrectomy to radical nephrectomy, providing significant guidance for preoperative risk assessment and clinical decision-making. However, our findings necessitate validation through studies with larger sample sizes.

Factors Predicting Overnight Admission after Same-Day Mastectomy Protocol and Associated Financial Implications.

Same-day mastectomy (SDM) protocols have been shown to be safe, and their use increased up to four-fold compared to pre-pandemic rates. We sought to identify factors that predict overnight patient admission and evaluate the associated cost of care. Patients undergoing mastectomy from March 2020 to April 2022 were analyzed. Patients' demographics, tumor characteristics, operative details, perioperative factors, 30-day complications, fixed and variable cost, and contribution margin (CM) were compared between those who underwent SDM vs. those who required overnight admission after mastectomy (OAM). Of a total of 183 patients with planned SDM, 104 (57%) had SDM and 79 (43%) had OAM. Both groups had similar demographic, tumor, and operative characteristics. OAM patients were more likely to be preoperative opioid users (POU) (p=0.002), have higher American Society of Anesthesiology (ASA) class (p= 0.028), and more likely to have procedure start time (PST) after 12:00 PM (49% vs. 33%, p=0.033). The rates of 30-day unplanned postoperative events were similar between SDM and OAM. POU (OR 3.62 CI 1.56 - 8.40), PACU length of stay greater than one hour (OR 1.17 CI 1.01 - 1.37), and PST after 12:00 PM (OR 2.56 CI 1.19 - 5.51), were independent predictors of OAM on multivariate analysis. Both fixed ($ 5,545 vs $4,909, p=0.03) and variable costs ($6,426 vs $4,909, p=0.03) were higher for OAM compared to SDM. CM, was not significantly different between the two groups (-$431 SDM vs -$734 OAM, p=0.46). Preoperative opioid use, ASA class, longer PACU length of stay, and PST after noon predict a higher likelihood of admission following planned SDM. OAM translated to higher costs, but not to decreased profit for the hospital.

Burden and mortality of congenital gastrointestinal anomalies: insights from a nationwide cohort study.

Improved perioperative care has enhanced survival in children with congenital gastrointestinal conditions and abdominal wall defects (AWD). However, epidemiological and surgical outcomes in developing nations are still scarce. Our aim was to assess the burden and mortality of common congenital gastrointestinal anomalies and AWD in Malaysia, and their influencing factors. Using the Global PaedSurg study protocol with permission, we performed a prospective cohort study on children presenting for the first time between October 2021 and April 2022 with these conditions: Esophageal atresia (EA), congenital diaphragmatic hernia (CDH), intestinal atresia, gastroschisis, exomphalos, anorectal malformation (ARM) and Hirschsprung's disease. We compared mortality and 30-day outcome data across different geographical regions in Malaysia. There were 228 patients with 242 study conditions (EA n = 28, CDH n = 36, intestinal atresia n = 49, gastroschisis n = 12, exomphalos n = 8, ARM n = 77, Hirschsprung's disease n = 32). Our mortality rate was 8.8%; 60% of these were CDH patients. Factors significantly associated with mortality were CDH diagnosis, central venous access requirement, higher American Society of Anesthesiologists (ASA) score, blood transfusion and ventilation requirement. Diagnosis of CDH is the most important predictor for sepsis on arrival and mortality, therefore measures should be taken for early recognition and aggressive management.

Routine single-incision laparoscopic common bile duct exploration with concomitant cholecystectomy for elderly patients: a 6-year retrospective comparative study.

While single-incision laparoscopic cholecystectomy (SILC) has gained more popularity in recent years, its application to elderly patients needs further evaluation. Few SILC studies regarded this rapidly growing vulnerable population, and single-incision laparoscopic common bile duct exploration (SILCBDE) was never mentioned. We conducted an observational study of 146 routine SILCBDE to address this issue. One hundred forty-six consecutive patients underwent SILCBDE with concomitant cholecystectomies during a period of 6 years (July 2012-June 2016 and July 2018-July 2020). Forty patients with an age of 65years or older were the study target. Characteristics and operative outcomes were compared with the remaining 106 younger patients by retrospective chart review. The primary outcomes include complications and mortality, while the secondary outcomes contain intraoperative blood loss, operative time, procedural conversions, postoperative length of hospital stay, and bile duct stone recurrence. There was no mortality. The bile duct stone clearance rate was 98.6%. The elderly group had higher American Society of Anesthesiologists (ASA) scores, higher comorbidity rate, higher acute cholangitis rate, lower completion intraoperative cholangiography (IOC) rate, longer operative time, more blood loss, longer postoperative hospital stay (p < .001), longer total hospital stay (p < .001), higher procedural conversion rate (p < .05), higher complication rate (p < .001), and the exclusive open conversion (2.5%). The difference in complications derived from Clavien-Dindo grade I. Routine SILCBDE with concomitant cholecystectomy by experienced surgeons is safe and efficacious for elderly patients as for younger patients. Randomized controlled trials are anticipated.

Unveiling Factors Influencing Mortality in Irish Hip Fracture Patients: A Comprehensive Five-Year Analysis

BackgroundHip fractures impose a substantial healthcare burden, contributing to increased morbidity, disability, and mortality. The Irish Hip Fracture Standards (IHFS) were officially employed in 2017, providing specialized pathways for hip fracture care to improve patient outcomes. This study evaluated the performance of our unit regarding hip fracture care and analyzed individual outcome parameters. MethodData spanning five years (2015 to 2019) preceding the COVID-19 era was extracted from our hip fracture repository. Patients aged 60 years and older were included. The dataset integrated demographic information and outcomes, validating mortality events using the Irish death events registry. Mortality rates were measured cumulatively and at various time intervals. ResultsThere were 1,685 hip fractures treated during the study timeframe average patient age was 78, with women constituting 68% of the cohort. The one-year mortality rate was 20.8% (n = 350). Adverse outcomes were observed in older patients, men, and those who had higher American Society of Anesthesiologists (ASA)scores. Patients adhering to IHFS 1 (P ≤ 0.05) and IHFS 2 (P ≤ 0.05) exhibited improved outcomes. Our institution displayed lower compliance rates with IHFS 1 and 2 when compared to standards 3 to 6, with the latter standards showing no significant impact on mortality outcomes. ConclusionWhile our unit's hip fracture care outcomes align well with national averages, resource constraints hinder full compliance with IHFS 1 and 2, emphasizing the need for targeted resource allocation in areas with the greatest impact on outcomes.

POST-MASTECTOMY SURGICAL SITE INFECTION RATES IN FEMALES WITH BREAST CARCINOMA IN PREMENOPAUSAL AGE: A SINGLE CENTER STUDY

Breast surgery, like mastectomy, is generally considered a low-risk procedure for surgical site infections (SSIs), but when SSIs do occur, they can lead to significant complications. Identifying risk factors to improve patient outcomes and minimize complications is essential. Objective: This study aimed to determine the frequency of post-mastectomy surgical site infections (SSI) in premenopausal females with breast carcinoma and to identify the associated risk factors. Methods: This descriptive case study included 100 premenopausal females diagnosed with breast carcinoma who underwent mastectomy at a tertiary care hospital, Shaikh Zayed Hospital Lahore, from April 2024 to August 2024. The age range of participants was 25-45 years, with a mean age of 39 ± 5.3 years. Demographic data, including age, gender, body mass index (BMI), comorbidities, and American Society of Anesthesiologists (ASA) score, were collected. Intraoperative variables such as blood loss (mean: 350 ± 50 ml) and surgery duration (mean: 120 ± 15 minutes) were also recorded. All patients received standard postoperative antibiotic prophylaxis, including cefazolin or clindamycin, for those allergic to penicillin. The surgical site was assessed 30 days postoperatively for signs of infection, including erythema, pus discharge, or fever exceeding 38°C. SSIs were categorized based on the Centers for Disease Control and Prevention (CDC) guidelines into superficial, deep, and organ/space infections. Results: The overall infection rate was 7.5% (n=7). Of these, 4 cases were superficial infections, while 3 involved deeper tissue layers, requiring drainage and further antibiotics. Factors significantly associated with an increased risk of disease in the multivariate logistic regression model included a high wound class (contaminated or dirty; OR: 3.2, p=0.01), elevated ASA score (ASA III-IV; OR: 2.8, p=0.03), high BMI &gt;30 (OR: 3.5, p=0.002), diabetes (OR: 4.1, p=0.001), use of surgical drains (OR: 2.9, p=0.02), and reoperation (OR: 4.3, p=0.005). The mean hospital stay was extended by 4.5 days (from 5.2 ± 1.5 days in non-infected patients to 9.7 ± 3.1 days in infected cases). Conclusion: The study found a post-mastectomy surgical site infection rate of 7.5% in premenopausal females, with significant risk factors including high BMI, diabetes, use of surgical drains, and the need for reoperation. A high wound class and elevated ASA score also predicted increased infection risk. Addressing these modifiable risk factors through optimized perioperative care, such as better glycemic control, judicious use of surgical drains, and minimizing reoperations, may help reduce SSI rates and improve outcomes for breast cancer patients.

374. INCIDENCE AND PREDICTORS OF STRICTURE DEVELOPMENT FOLLOWING ESOPHAGECTOMY: A RETROSPECTIVE ANALYSIS

Abstract Objective Anastomotic stricture (AS) is a well described complication after esophagectomy and not only affects nutritional status but also has a detrimental impact on long-term quality of life. This retrospective study explores the incidence of clinically relevant AS in patients undergoing esophagectomy for cancer and investigates the potentially reversible factors associated with AS. Methods A prospectively entered clinical database of consecutive patients undergoing esophagectomy at a high-volume referral center over a decade (1/2013-12/2022) was queried for the presence of post-operative clinically significant AS, defined as stricture requiring endoscopic dilation. Multiple variables encompassing patient-related risk factors, tumor pathology, prior treatment, operative factors, and post-op complications were included in logistic regression analyses to delineate predictors of stricture formation. Results Of 1015 patients in the database, 115 (11.3%) developed AS requiring at least 1 post-op dilation. Although higher American Society of Anesthesiologists (ASA) grading was associated with elevated AS rate impact with most patients being ASA 2 and 3; 24% and 49% respectfully (p &amp;lt; 0.05). Specific patient factors/comorbidities such as age, peripheral or coronary vascular disease, and diabetes mellitus did not emerge as significant predictors. Surprisingly, neither histology, nor neoadjuvant therapy (chemo or chemoradiation) were associated with AS. Both a cervical anastomosis and a intra-operative pyloromyotomy had a higher AS rate than an intra-thoracic anastomosis (OR 13.3, p=0.006) and patients without a myotomy (p=&amp;lt;0.006). Other operative factors including approach (open vs MIE) conduit type (stomach/jejunum/colon) or width (3/4/5/6 cm) did not impact AS rate. All patients had a hand-sewn anastomosis. No post-operative outcome measures (e.g. leak, epidural use, hypotension) was associated with the development of AS. Conclusion Our results highlight the interplay of patient-related risk factors, tumor pathology, prior treatment, and operative factors in the development of post esophagectomy strictures. Understanding these predictors could potentially influence risk stratification and may facilitate tailored postoperative care strategies for improved patient outcomes.

Long-term quality of life and influencing factors in elderly patients after vertebroplasty based on the EQ-5D-3L Chinese utility scoring system: a retrospective study

BackgroundThe quality of life of elderly patients after vertebroplasty is influenced by various factors. Although the EuroQol 5-Dimension 3-Level (EQ-5D-3L) scale has been widely used to assess quality of life, the factors affecting the long-term postoperative quality of life of elderly vertebroplasty patients in China have not been thoroughly studied.MethodsThis retrospective study included 519 patients aged 65 years and older who underwent elective vertebroplasty. We collected baseline data from these patients and conducted telephone follow-ups 12 months postoperation to evaluate their EQ-5D-3L health utility scores and EuroQol Visual Analogue Scale (EQ-VAS) scores. Univariate and multivariate linear regression models were used to analyse the factors affecting quality of life.ResultsOf the 519 patients, the majority were female (78.0%), aged 65 to 95 years, with an average age of 75.2 years. Twelve months postoperation, pain/discomfort was the most commonly reported issue for 68.4% of patients. The median EQ-5D-3L health utility score was 0.783, with a range between 0.450 and 0.887; the median EQ-VAS score was 75, ranging from 60 to 85. Multivariate linear regression analysis indicated that older age, hormone use, higher American Society of Anesthesiologists (ASA) grades, nondrinking habits, and low albumin levels were found to be independent risk factors affecting long-term quality of life in elderly patients after vertebroplasty. Additionally, a history of tumours, the number of vertebral compression fractures, and bone mineral density were also crucial influencing factors.ConclusionsBased on the use of the EQ-5D-3L Chinese utility scoring system, we evaluated the quality of life of patients aged 65 and above 12 months after vertebroplasty. This study identified several factors related to postoperative quality of life in elderly vertebroplasty patients, providing crucial evidence for further clinical decisions and patient education.

Does neoadjuvant chemotherapy reduce surgical complexity in patients with advanced-stage epithelial ovarian cancer?

BackgroundThis study aimed to determine the effect of neoadjuvant chemotherapy (NACT) on the complex surgical procedures required in addition to staging surgery for the need to achieve a residual tumor 1 cm or less in a population of stage IIIC–IV epithelial ovarian cancer patients.MethodsPatients were referred for NACT if preoperative imaging and/or intraoperative evaluation confirmed that it was not possible to achieve a residual tumor size of 1 cm or less with cytoreductive surgery or if the patient had a poor performance status and a high American Society of Anesthesiologists (ASA) score. Surgical complexity was defined as complex or non-complex.ResultsOne hundred and twenty-six patients with stage IIIC–IV ovarian cancer were included in the study. Primary cytoreductive surgery was performed in 67 patients, and interval cytoreductive surgery was performed in 59 patients after NACT. At least one complex surgery was performed in 74.6% of the patients in the primary cytoreductive surgery group and in 61% of the patients in the NACT group, with no statistically significant difference between the groups. However, the NACT group showed significantly decreased rates of low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy.ConclusionsThe analyses showed no reduction in the requirement for at least one complex surgical procedure in the group of patients who underwent NACT. Nevertheless, this group exhibited a significant decrease in low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy due to their effectiveness in reducing peritoneal disease.

Changes in pituitary adenoma patient presentation and outcomes during the COVID pandemic at a Pituitary Center of Excellence.

The COVID-19 pandemic caused significant disruption to the surgical care of patients. The aim of this study was to analyze the impact of the pandemic on endoscopic endonasal surgery (EES) for patients with a pituitary adenoma. Patients from 2015 to 2022 that had EES for a pituitary adenoma were included in this study. Patients were separated into pre-COVID (January 2015-March 2020) and COVID (March 2020-September 2022) groups. Univariate analysis was done using chi-square, fisher exact tests, and t-tests to compare groups. This study included 492 patients that had EES for their pituitary adenoma. There were 314 patients in the pre-COVID group and 178 patients in the COVID group. Patients in the COVID group had a higher risk analysis index (RAI) frailty score (15 ± 10 pre-COVID vs. 20 ± 9 COVID, P < 0.001) and a higher American Society of Anesthesiology (ASA)physical status score (3 or 4) (72.0% pre-COVID vs. 81.9% COVID, P = 0.02). There were significantly more macroadenoma cases (87.6% pre-COVID vs. 94.4% COVID, P = 0.02) and extrasellar surgical approaches (45.2% pre-COVID vs. 61.2% COVID, P < 0.001) during COVID. There was no significant difference in length of stay (LOS) and readmission rates between groups. Patients that presented during the pandemic tended to be more frail, have more comorbidities, and require additional extrasellar surgical approaches. Despite changes in clinical presentation and operative management, the LOS and readmission rate remained stable during COVID, supporting the safety of this procedure during the recent pandemic.

Determinants of prehospital and in-hospital delay in patients with symptomatic carotid stenosis and their influence on the outcome after elective carotid endarterectomy

BackgroundThis study analyses the determinants of prehospital (index event to admission) and in-hospital delay (admission to carotid endarterectomy (CEA)). In addition, the analysis addresses the association between prehospital or in-hospital...

Effects of anesthesia and perioperative management on mortality in geriatric orthopedic surgery: a retrospective study of 451 patients.

We aimed to investigate the effects of anesthesia methods and perioperative procedures on mortality in geriatric patients operated for hip fracture. This retrospective study included patients over 65 years of age who underwent hip fracture surgery. Demographic data, risk scores, perioperative and anesthesia management were analyzed in terms of mortality. Data from 451 patients who were eligible for the study were analyzed. It was determined that there was no difference in mortality between the anesthesia methods administered to the patients in hip fracture surgery (p>0.05). Being male increased the mortality risk by 4.568 times (95% CI: 1.215-17.168), and a one-unit increase in the number of erythrocyte suspensions given perioperatively increased the mortality risk by 2.801 times (95% CI: 1.509-5.197). Additionally, an American Society of Anesthesiologists (ASA) II score increased the mortality risk by 0.120 times (95% CI: 0.021-0.690), and a higher modified Charlson comorbidity index (mCCI) of 5-7 increased the mortality risk by 0.052 times (95% CI: 0.009-0.289). Although high ASA and mCCI scores, male sex, and blood transfusion were associated with mortality in geriatric hip fracture surgery, we found that the method of anesthesia did not affect mortality.

Functional Outcomes and Satisfaction Rates in Patients Aged 80 Years or Older are Not Clinically Different From Their Younger (65 to 75 Years) Counterparts Following Total Hip Arthroplasty

BackgroundAs the population ages, the proportion of elderly patients requiring total hip arthroplasty (THA) increases, but it is not clear whether older age independently influences outcome. The aim was to assess function, quality of life, and satisfaction after THA in patients ≥ 80 years compared with those aged between 65 and 75 years when adjusting for confounding factors. MethodsA single-center retrospective cohort study was performed between 2010 and 2019. A total 2,367 THAs were performed on patients ≥ 80 years and 5,113 on patients aged 65 to 75 years. The demographic data and length of stay (LOS) were recorded. Preoperative and 2-year postoperative Oxford Hip Scores (OHS), EuroQol (EQ-5D), and satisfaction scores were collected. Clinically meaningful difference was defined as 5 points in OHS and utility of 0.085 in EQ-5D. Regression analyses were performed to adjust for confounding factors. ResultsPatients in ≥ 80-years group were more likely women (P < .001), have higher American Society of Anesthesiolgists grade (P < .001), worse preoperative OHS (mean difference [MD] 2.3, P < .001), and EQ-5D (MD 0.087, P < .001). Both age groups achieved clinically meaningful and statistically significant (P < .001) improvement in OHS and EQ-5D utility at 2 years. When adjusting for confounding variables, the ≥ 80-year-old group had significantly (P < .001) lower improvement in OHS (MD -1.9 points) and EQ-5D (MD −0.055 utility), but these differences were not clinically meaningful. There was no difference (P = .813) in satisfaction between the groups. When adjusting for confounding variables, ≥ 80-year-old group had increased risk of longer LOS (odds ratio 1.27, P < .001). ConclusionsThere were no clinically meaningful differences in hip-specific outcome or health-related quality of life according to age group, and both were equally satisfied with their outcome. The older age group did, however, have longer LOS. Level of evidenceLevel III retrospective cohort study.

Technical Aspects and Outcome of Multi-Staged and Single-Staged Thoracoabdominal Fenestrated Endovascular Aortic Repair.

In some cases of endovascular thoracoabdominal or juxtarenal aortic aneurysm repair, a thoracic endograft in combination with a fenestrated renovisceral device may be needed in order to create a sufficient proximal landing zone. This study aimed to evaluate the technical aspects and postoperative morbidity of a single- or 2-stage approach. Eighty-seven consecutive patients undergoing thoracic endovascular aortic repair (TEVAR) in combination with elective fenestrated repair (fenestrated endovascular aortic repair [FEVAR]; fenestrated Anaconda device) from 2015 to 2022 were included in this retrospective bicentric study. Underlying pathologies, aortic morphology, technical details, and postoperative morbidity were recorded. Single-staged ("1S," n=61) and 2-staged ("2S," n=26) interventions were compared. Indications were thoracoabdominal aneurysms (TAAAs) (Crawford I-IV) (n=56, 64%) and juxtarenal aneurysms (n=31, 36%). In 2S, the proportion of TAAA was higher than in 1S (2S: 77%, 1S: 59%; p=0.001). In 2S, the covered length of the descending aorta was longer (1S: 128±60 mm, 2S: 202±64 mm; p=0.003). Temporary aneurysm sack perfusion (TASP) was established in 11 (18%) of 1S and 1 (4%) of 2S patients (p=0.079), as well as cerebrospinal fluid (CSF) drainage catheter in 48 (79%) of 1S and 19 (73%) of 2S. The rate of spinal cord ischemia (SCI) and the severity of SCI were not different in both groups, with a total of 3 cases of persisting paraplegia. The rate of access complications was higher in 2S (n=6, 23%) than in 1S (n=4, 7%; p=0.027). Postoperative 30 day morbidity did not significantly differ in both groups and neither did 30 day mortality (4.6% in 1S vs 3.8% in 2S; p=0.083). The combination of TEVAR and FEVAR using a fenestrated endograft is feasible and safe. Aortic morphology does not change significantly after endovascular repair. A single-staged strategy is feasible with excellent results, especially in Crawford IV, Crawford V, or juxtarenal aneurysms. Two-staged repair is recommended in cases with long aortic coverage and a higher American Society of Anesthesiologists (ASA) class. Follow-up data are needed to evaluate the long-term stability of the TEVAR/FEVAR interconnection. Our study has revealed the safety and efficacy of the combination of TEVAR and FEVAR in the treatment of TAAAs and juxtarenal aneurysms with compromised supravisceral landing zones. A single-staged concept is not necessary in all cases. Staged procedures may reduce postoperative morbidity in cases with long aortic coverage and higher ASA class.

The outcome of revision total hip arthroplasty for instability.

Instability is a common indication for revision total hip arthroplasty (THA). However, even after the initial revision, some patients continue to have recurrent dislocation. The aim of this study was to assess the risk for recurrent dislocation after revision THA for instability. Between 2009 and 2019, 163 patients underwent revision THA for instability at Stanford University Medical Center. Of these, 33 (20.2%) required re-revision due to recurrent dislocation. Cox proportional hazard models, with death and re-revision surgery for periprosthetic infection as competing events, were used to analyze the risk factors, including the size and alignment of the components. Paired t-tests or Wilcoxon signed-rank tests were used to assess the outcome using the Veterans RAND 12 (VR-12) physical and VR-12 mental scores, the Harris Hip Score (HHS) pain and function, and the Hip disability and Osteoarthritis Outcome score for Joint Replacement (HOOS, JR). The median follow-up was 3.1 years (interquartile range 2.0 to 5.1). The one-year cumulative incidence of recurrent dislocation after revision was 8.7%, which increased to 18.8% at five years and 31.9% at ten years postoperatively. In multivariable analysis, a high American Society of Anesthesiologists (ASA) grade (hazard ratio (HR) 2.72 (95% confidence interval (CI) 1.13 to 6.60)), BMI between 25 and 30 kg/m2 (HR 4.31 (95% CI 1.52 to 12.27)), the use of specialized liners (HR 5.39 (95% CI 1.97 to 14.79) to 10.55 (95% CI 2.27 to 49.15)), lumbopelvic stiffness (HR 6.03 (95% CI 1.80 to 20.23)), and postoperative abductor weakness (HR 7.48 (95% CI 2.34 to 23.91)) were significant risk factors for recurrent dislocation. Increasing the size of the acetabular component by > 1 mm significantly decreased the risk of dislocation (HR 0.89 (95% CI 0.82 to 0.96)). The VR-12 physical and HHS (pain and function) scores improved significantly at mid term. Patients requiring revision THA for instability are at risk of recurrent dislocation. Higher ASA grades, being overweight, a previous lumbopelvic fusion, the use of specialized liners, and postoperative abductor weakness are significant risk factors.

Management of groin hernia repair in Sweden: A register-based comparative analysis of public and private healthcare providers.

Swedish healthcare is in a period of transition with an expanding private sector. This study compares quality of outcome after groin hernia repair performed in a public or private healthcare setting. A cohort study based on data from the Swedish National Hernia Register combined with Patient-Reported Outcome Measures (PROMs) 1 year after groin hernia repair. Between September 2012 and December 2018, a questionnaire was sent to all patients registered in the hernia register 1 year after surgery. Endpoints were reoperation for recurrence, chronic pain, and patient satisfaction. From a total of 87,650 patients with unilateral groin hernia repair, 61,337 PROM answers (70%) were received from 71 public and 28 private healthcare providers. More females, acute and recurrent cases, and patients with high American Society of Anesthesiology (ASA) scores were operated under the national healthcare system. The private sector had more experience surgeons with higher annual volume per surgeon, shorter time on waiting lists, and shorter operation times. No difference was seen in patient satisfaction. Groin hernia repair performed in a private clinic was associated with less postoperative chronic pain (OR 0.85, 95% CI 0.8-0.91) but a higher recurrence rate (HR 1.41; 95% CI 1.26-1.59) in a multivariable logistic regression analysis. Despite private clinics having a higher proportion of experienced surgeons and fewer complex cases, the recurrence rate was higher, whereas the risk for chronic postoperative pain was higher among patients treated in the public sector.

The Prevalence of Difficult Airway and Associated Risk Factors in Pediatric Patients: A Cross-sessional Observational Study.

Difficult airway remains a great challenge in pediatric anesthesia practice. Previously published data show the prevalence of difficult airways in pediatric population varies in a wide range. However, there is a lack of studies in the Asian region. This cross-sectional single-center study was conducted in a tertiary pediatric hospital in China from October 2022 to October 2023. The patients who underwent elective surgery under general anesthesia with tracheal intubation were recruited consecutively. Data on patient characteristics, airway assessment, and airway management information were collected. Multivariable logistic regression analysis was performed to detect the independent variables of difficult airway in pediatric patients. A total of 18,491 pediatric patients were included in this study. The overall incidence of difficult airways was 0.22%, 39% of whom were unanticipated. Very few previous airway management information was available in the patients presented with a known difficult airway. Patients with younger age, higher American Society of Anesthesiologists (ASA) physical status classification grade, and presented for craniofacial and thoracic surgery were associated with higher incidence of difficult airway. Further multivariable logistic regression analysis revealed that age ≤28 days (OR=50.48), age between 28days and 1 year (OR=6.053), craniofacial surgery (OR=1.81), and thoracic surgery (OR=0.2465) were independent risk factors of increased incidence of difficult airway. Our study showed the prevalence of difficult airways in pediatric surgical patients. Patient characteristics, age, and type of surgery were identified as the independent factors associated with increased occurrence of difficult airways. Unanticipated difficult airway was not unusual in our study population, even for the patients with previous surgical history.

Assessment of routine pre-operative group and save testing in patients undergoing cholecystectomy: a retrospective cohort study

Background Routine group and save (G&amp;S) testing is frequently performed prior to cholecystectomy, despite growing evidence that a targeted approach is safe and avoids unnecessary investigations. This retrospective cohort study explored frequency of testing in our unit, and rates of and independent pre-operative risk factors for peri-operative blood transfusion. Methods Health records of 453 consecutive adults who underwent cholecystectomy in a UK NHS trust were reviewed for blood transfusion up to 30 days post-operatively. We compared the need for transfusion against patient demographics, indication and urgency of surgery, and the number of prior emergency hospital attendances with gallstone complications. Logistic regression determined whether prior attendances with complications of gallstones independently predicted the need for transfusion. Results Peri-operative blood transfusions within 30 days of operation occurred in 1.1% of cases, with no requirement for uncrossmatched blood. Patients who received a blood transfusion tended to have higher American Society of Anesthesiologists (ASA) grades (p&lt;0.001), were more likely to have an underlying primary haematological malignancy (20.0% vs. 0.2%; p&lt;0.001) and prior emergency hospital attendances with gallstone complications (median 4 vs. 1; p&lt;0.001). Logistic regression showed each prior emergency attendance was associated with 4.6-fold odds of transfusion (p=0.019). Receiver operating characteristic curve analysis showed an area under the curve of 0.92. Three or more attendances predicted need for transfusion with 60.0% sensitivity and 98.0% specificity. Seventy-four percent had at least one G&amp;S sample taken pre-operatively, costing the trust approximately £3,800 per year in materials. Conclusions Pre-operative G&amp;S testing prior to cholecystectomy may not be routinely required. Increased frequency of prior emergency hospital attendances with gallstone complications and co-morbidities associated with coagulopathies were pre-operative risk factors for post-operative blood transfusion. More selective testing could provide large financial savings for health institutions without compromising patient safety.

Psychiatric Diagnosis Does Not Influence Management or Resolution of Confirmed Fracture-Related Infection.

The purpose of this study was to determine if the presence of a standing Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, psychiatric diagnosis is associated with worse outcomes for patients who develop a confirmed fracture-related infection (FRI). Included patients had open or closed fractures managed with internal fixation and had confirmed FRIs. Baseline demographics, injury information, and outcomes were collected via chart review. All patients who had a diagnosis of psychiatric illness, which included depression, bipolar disorder, anxiety disorder, and schizophrenia, were identified. Patients with and without a psychiatric diagnosis were statistically compared. Two hundred eleven patients were diagnosed with a confirmed FRI. Fifty-seven (27.0%) patients had a diagnosis of a psychiatric illness at the time of FRI diagnosis. Patients with a psychiatric diagnosis had a higher rate of smoking (56% vs 40%, P=.039) and drug use (39% vs 19%, P=.004) and a higher American Society of Anesthesiologists (ASA) classification (2.35±1.33 vs 1.96±1.22, P=.038); however, there were no other demographic differences. Clinical outcomes also did not differ between the groups, as patients with an FRI and a psychiatric diagnosis had a similar time to FRI diagnosis, similar confirmatory FRI characteristics, and a similar rate of reoperation. Furthermore, there was no difference between patients with FRI with and without a psychiatric diagnosis regarding rate of infection resolution (89% vs 88%, P=.718) or time to final follow-up (20.13±24.93 vs 18.11±21.81 months, P=.270). The presence of a psychiatric diagnosis does not affect clinical outcomes in the patient population with FRI. This is the first study exploring the impact of psychiatric illness on patient outcomes after a confirmed FRI diagnosis. [Orthopedics. 2024;47(4):198-204.].
