Short-term outcomes with routine use of size ≥40 femoral heads in THA: A retrospective cohort study.

Background: Using larger femoral heads during total hip arthroplasty (THA) may result in a more stable hip. Greater volumetric wear and frictional torque, however, may result in increased postoperative complications. The purpose of this study was to compare outcomes of patients with femoral head size ≥40 mm compared to those with femoral head size <40 mm. Materials and methods: A retrospective chart review of 504 THAs performed by a single surgeon at a single institution from 2009 to 2016 was conducted. Following exclusions, 131 THAs were identified with femoral heads ≥40 mm and 348 THAs were identified with femoral heads <40 mm. In addition to demographic data, all postoperative complications were recorded. Plain radiographs were used to rule out/in periprosthetic osteolysis and/or acetabular loosening. Chi-square tests and Student's t-tests were used to compare categorical and continuous variables, respectively. Results: Mean follow-up period for the entire cohort was 5.5 years. Complications with ≥40 mm femoral heads included 1 superficial infection and 1 deep periprosthetic joint infection (PJI). There were no cases of dislocation, osteolysis, acetabular loosening, or trunnionosis. In contrast, complications with <40 mm femoral heads included 9 dislocations and 7 PJIs. Conclusion: The routine use of large femoral heads (≥40-mm) during THA appears to be a safe option for patients at short-term clinical follow-up. Notably, 0 patients had a clinical course complicated by dislocation, osteolysis, acetabular loosening, or trunnionosis. Level of evidence: Level III Retrospective Cohort Study.

The effect of puboperiurethral suspension stitch placement on climacturia after robot-assisted laparoscopic radical prostatectomy.

BACKGROUND: Climacturia is defined as urine leakage associated with orgasm and can negatively affect patients' quality of life. The high prevalence of climacturia after radical prostatectomy (RP) has led to continued efforts to reduce climacturia rates. It has been shown that puboperiurethral suspension stitch placement during RP assists in the recovery of urinary continence. AIM: To evaluate the impact of puboperiurethral suspension stitch placement during RP on post-RP climacturia. METHODS: We conducted a retrospective study of patients who underwent nerve-sparing robot-assisted laparoscopic RP (RALP) at our institution between 2016 and 2023. The patients were categorized into 2 groups: Group 1 (n = 32) that underwent nerve-sparing RALP with puboperiurethral suspension stitch placement and Group 2 (n = 62) that underwent nerve-sparing RALP alone. Patients who were not able to achieve penetration at the last follow-up visit were excluded from the study. The clinical history, parameters of prostate cancer, details of medical and surgical treatments, and follow-up data were evaluated. OUTCOMES: Differences in sexual and urinary function, climacturia rates, and complications between nerve-sparing RP with and without puboperiurethral suspension stitch placement. RESULTS: There were no significant differences between the groups in terms of surgical complications. The mean follow-up time was 14.62 ± 3.55 months in Group 1 and 14.43 ± 4.44 months in Group 2 (P = .42). Postoperative erectile functions were similar between the groups. At the last follow-up visit, climacturia was present in 4 patients (12.5%) in Group 1 and 24 patients (38.7%) in Group 2 (P = .016). The long-term stress urinary incontinence rates were similar between the groups. CLINICAL IMPLICATIONS: This study provides comparative results on postoperative climacturia rates between nerve-sparing RALP groups with and without puboperiurethral suspension stitch placement. These results show that puboperiurethral suspension stitch can help to prevent postoperative climacturia after RP. STRENGTH AND LIMITATIONS: This is the first study in the literature that evaluates the effect of puboperiurethral suspension stitch on climacturia. The limitations include the single-center, retrospective design with potential selection bias, possible inaccuracies in the recorded medical data, and challenges in controlling confounding variables. CONCLUSION: Our study demonstrated that puboperiurethral suspension stitch was a feasible option for the prevention of climacturia after RALP without an increased risk of complications.

Laparoscopic colectomy for patients with poor American Society of Anesthesiology classifications.

INTRODUCTION: The American Society of Anesthesiologists (ASA) classification is used to assess the fitness of a patient for surgery. Whether laparoscopic surgery is appropriate for colorectal cancer patients with poor ASA performance status (PS) remains unclear. METHODS: Among 4585 patients who underwent colorectal surgery between 2016 and 2023, this study retrospectively reviewed all 458 patients with ASA-PS ≥3. Patients were divided into two groups: patients treated by open surgery (O group, n = 80); and patients treated by laparoscopic surgery (L group, n = 378). We investigated the impact of surgical approach on postoperative complications in patients with colorectal cancer and ASA-PS ≥3. RESULTS: Operation time was longer (170 min vs. 233 min, p < .001), blood loss was less (156 mL vs. 23 mL, p < .001), postoperative complications were less frequent (40.0% vs. 25.1%, p = .008), and hospital stay was shorter (23 days vs. 14 days, p < .001) in L group. Univariate analysis revealed rectal cancer, open surgery, longer operation time, and blood loss as factors significantly associated with postoperative complications. Multivariate analysis revealed open surgery (odds ratio [OR] 2.100, 95% confidence interval [CI] 1.164-3.788; p = .013) and longer operation time (OR 1.747, 95% CI 1.098-2.778; p = .018) as independent predictors of postoperative complications. CONCLUSION: Laparoscopic surgery provides favorable outcomes for colorectal cancer patients with poor ASA-PS.

From diagnosis to postoperative challenges: a comprehensive case report on 2q37 deletion syndrome with CHD.

Chromosomal 2q37 deletion syndrome, marked by developmental delays, distinctive facial features, and a spectrum of congenital anomalies, presents significant challenges in the cardiac management of affected individuals. This paper details the case of an 8-month-old male with 2q37 deletion syndrome, manifesting atrial and ventricular septal defects, patent ductus arteriosus, and right ventricular outflow tract stenosis, leading to a demanding postoperative course. Despite an initially stable post-surgery phase, the onset of junctional ectopic tachycardia necessitated prolonged veno-arterial extracorporeal membrane oxygenation support, highlighting the syndrome's potential for intricate postoperative courses. The complexities encountered in this case, including extended renal replacement therapy and delayed thoracic closure, underscore the syndrome's multisystem impact and the critical need for tailored, multidisciplinary care approaches. This report contributes to the growing body of knowledge on the cardiac implications of 2q37 deletion syndrome, emphasising the importance of individualised surgical strategies and the ongoing exploration of genotype-phenotype correlations in this rare genetic disorder.

Machine learning as a tool predicting short-term postoperative complications in Crohn's disease patients undergoing intestinal resection: What frontiers?

The recent study, "Predicting short-term major postoperative complications in intestinal resection for Crohn's disease: A machine learning-based study" investigated the predictive efficacy of a machine learning model for major postoperative complications within 30 days of surgery in Crohn's disease (CD) patients. Employing a random forest analysis and Shapley Additive Explanations, the study prioritizes factors such as preoperative nutritional status, operative time, and CD activity index. Despite the retrospective design's limitations, the model's robustness, with area under the curve values surpassing 0.8, highlights its clinical potential. The findings align with literature supporting preoperative nutritional therapy in inflammatory bowel diseases, emphasizing the importance of comprehensive assessment and optimization. While a significant advancement, further research is crucial for refining preoperative strategies in CD patients.

Impact of the Prognostic Nutritional Index on the Development of Sialocele or Salivary Fistula, After Parotidectomy.

PURPOSE: Sialocele or salivary fistula formation is common after parotidectomy. This study aims to evaluate the predictive value of the prognostic nutritional index in the development of salivary fistulas and sialoceles after parotidectomy. METHODS: Patients who underwent parotidectomy at our clinic and were diagnosed with benign salivary gland masses were included in the study. Patients who developed postoperative sialoceles or salivary fistulas were identified. Various factors were assessed, including surgical technique, tumour size, gender, age, prognostic nutritional index, and the volume of the excised mass. Variables associated with sialocele or salivary fistula were later included in a multiple logistic regression model. Possible factors related to the formation of sialocele or salivary fistulas were analysed. RESULTS: The study comprised 158 patients (95 male and 63 female). The frequency of sialocele or salivary fistula development was 13.9% (n = 22). The multiple logistic regression model found that the prognostic nutritional index(PNI) was linked to the occurrence of sialocele or salivary fistula (ORs = 0.9, 95% CI = [0.9], p = 0.003). Warthin tumour was associated with an elevated risk of sialocele or salivary fistula (ORs = 0.38, 95% CI = [0.184, 0.79], p = 0.009). ROC analysis demonstrated that the PNI had a specificity of 90% and a sensitivity of 68%. No significant associations were observed between the excised tumour size, surgical technique with the development of sialocele or salivary fistula. CONCLUSION: Prognostic nutritional index can be utilised as an independent risk factor for the development of sialocele, or salivary fistula.

Assessment of Complications and Length of Hospital Stay Associated With Surgical Emergencies in Patients With Concurrent COVID-19 Infection.

The delivery of surgical services was profoundly affected by the COVID-19 pandemic, resulting in the postponement of elective surgeries and a shift in focus to essential emergency procedures. Our study aimed to assess the impact of concurrent COVID-19 infection on complications, hospital stay, and recovery following emergency surgery. A retrospective matched cohort study was conducted between July 2020 and February 2022 at a tertiary care hospital in India. Data from 48 patients with COVID-19 infection in the immediate preoperative period was compared with 48 matched controls not infected with the virus. The data collected included patient demographics, surgical procedures, duration of hospital stay, and postoperative complications. Patients with concurrent COVID-19 infection had notably longer mean hospital stays (13.44 days) than the controls (6.63 days) (P = 0.002). An elevated proportion of COVID-19-positive patients experienced discharge delays (36 out of 48, 75%), compared to just six of the 48 non-COVID-19 patients (12.5%) (P ≤ 0.001). Postoperative findings in the COVID-positive cohort revealed elevated rates of pulmonary complications (5/48, 10.4%), higher rates of postoperative ICU admissions (8/48, 16.7%), and persistently elevated D-dimer levels extending beyond postoperative day seven (18/48, 37.5%). This suggests that emergency surgery in patients with COVID-19 is linked to significantly lengthier hospital stays, increased discharge delays, and a greater prevalence of adverse events in the postoperative period when compared to controls. These findings underscore the need for enhanced perioperative strategies and preparedness for potential future pandemics.

Postoperative challenges addressed through nursing care of patients receiving lower extremity tumor prosthesis.

BACKGROUND: Patients with primary Bone Sarcoma and Giant Cell Tumors in the lower extremities often require major surgery involving tumor prostheses. The postoperative course for this patient group can be complex and influenced by various factors and challenges that demand careful nursing care. This study aims to identify challenges related to the nursing care of individuals with primary bone tumors following surgery for tumor prostheses in the lower extremities. METHODS: A retrospective cohort study of 15 patients treated at Rigshospitalet, Copenhagen, Denmark, between November 5. 2016, and April 1. 2020 was conducted by medical record review, focusing on challenges related to postoperative nursing care. All patients with the surgery code "Bone Excision" were identified within the surgery booking system and screened for eligibility. RESULTS: Patients experienced postoperative challenges such as severe pain, prolonged time to mobilization (mean: 4 days), and defecation (mean: 5 days). The mean length of stay at the Rigshospitalet was 13 days. Furthermore, eleven patients (73%) reported disrupted sleep and nausea. CONCLUSION: Patients undergoing tumor prosthesis surgery in the lower extremities face considerable postoperative challenges that contribute to a prolonged hospital stay. These challenges, including severe pain, delayed mobilization, and gastrointestinal issues, significantly impact recovery. The findings highlight the urgent need for targeted nursing interventions to address these issues effectively. Enhanced pain management protocols, early mobilization strategies, and comprehensive postoperative care plans are essential to improve patient outcomes and reduce the length of hospital stays. Addressing these challenges through dedicated nursing care is crucial for optimizing the recovery process for patients receiving lower extremity tumor prostheses.

TCD-Guided management in carotid endarterectomy: a retrospective study.

BACKGROUNDː: Stroke, primarily resulting from ischemic conditions, is the foremost cause of mortality and long-term impairment and is frequently associated with narrowing of the carotid arteries. Although carotid endarterectomy (CEA) is the treatment of choice, it carries the risk of cerebral ischemia and reduced blood flow. Transcranial Doppler (TCD) ultrasound offers a nonintrusive method to assess cerebral blood circulation during CEA, potentially enhancing surgical outcomes. The objective of this study was to assess the clinical utility and safety of TCD monitoring during CEA and to identify factors influencing postoperative complications. METHODS: This retrospective analysis included 158 CEA patients (from January 2021-August 2023) who underwent TCD monitoring and whose data were compared to historical standard care data. The primary outcomes were operation duration and artery occlusion time. Secondary outcomes included carotid shunt usage, seven-day postoperative complications, and six-month carotid artery patency. Logistic regression identified factors linked to adverse reactions, and a predictive model was evaluated with a receiver operating characteristic (ROC) curve. RESULTSː: Comparative analysis indicated significant reductions in both the duration of surgery (113.26 ± 7.29 min) and artery occlusion time (21.85 ± 2.92 min) for patients monitored with TCD (P < 0.001) and an increase in carotid shunt implementation (25% as opposed to traditional care). The observed postoperative complications were minor, with a nonsignificant trend that favored the use of TCD-monitored procedures (1% vs. historical rates). Factors such as patient age and plaque echogenicity were found to be predictive of postoperative issues, with plaque echogenicity emerging as a significant predictive factor (OR = 10.70, 95% CI: 2.14-202, P = 0.02) upon multivariate analysis. The predictive model exhibited high precision (AUC = 0.93). CONCLUSION: This retrospective evaluation suggested that TCD monitoring in the CEA may reduce procedural time and potentially decrease postoperative complications, supporting its use for personalized surgical planning.

Timing of total joint arthroplasty post-COVID-19: an evaluation of the optimal window to minimize perioperative risks.

BACKGROUND: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are commonly performed orthopedic procedures. This study aimed to evaluate the impact of COVID-19 status on postoperative complications and mortality in patients undergoing THA and TKA. METHODS: A total of 110,186 underwent either THA or TKA. Patients were grouped based on their COVID-19 status, gathered from the National COVID-19 Cohort Collaborative (N3C) in the 12 weeks preceding surgery and compared for various variables, including age, sex, BMI, and Charlson Comorbidity Index (CCI) scores. COVID-19 status was defined as a positive test result that was closest to the date of surgery regardless of testing positive previously. Postoperative complications such as venous thromboembolism (VTE), sepsis, surgical site infection, bleeding, acute kidney injury (AKI), 30-day, and 1-year all-cause mortality were examined. To compare the variables, an odds ratio with a 95% confidence interval was calculated with a significant level set at P < 0.05. Logistic regression using R programming was utilized for these calculations. RESULTS: Univariate analysis was performed and rates of VTE (1.02% vs. 3.35%), 30-day mortality (0.25% vs. less than 5%), and 1-year mortality (1.42% vs. 5.43%) were higher in the COVID-19-positive group for THA patients (P < 0.001). For TKA patients, only 30-day mortality was significantly higher in the COVID-19-positive group (P = 0.034). Multivariate logistic regression revealed that a positive COVID-19 diagnosis within two weeks of surgery and a CCI score > 3 were significant predictors of postoperative complications and mortality for both TKA and THA. CONCLUSIONS: Patients with a positive COVID-19 diagnosis within 12 weeks of THA or TKA carried a significantly higher risk for postoperative complications and mortality. In addition, a CCI score > 3 is also a significant risk factor. These findings emphasize the importance of vigilant preoperative screening and risk stratification in the era of COVID-19.

Impact of rapid response system in mortality and complications post-orthopedic surgery: a retrospective cohort study.

BACKGROUND: Rapid response systems (RRSs) are used in hospitals to identify and treat deteriorating patients. However, RRS implementation and outcomes in orthopedic and surgical patients remain controversial. We aimed to investigate whether the RRS affects mortality and complications after orthopedic surgery. METHODS: The National Health Insurance Service of South Korea provided the data for this population-based cohort study. Individuals who were admitted to the hospital that implemented RRS were categorized into the RRS group and those admitted to a hospital that did not implement the RRS were categorized into the non-RRS group. In-hospital mortality and postoperative complications were the endpoints. RESULTS: A total of 931,774 adult patients were included. Among them, 93,293 patients underwent orthopedic surgery in a hospital that implemented RRS and were assigned to the RRS group, whereas 838,481 patients were assigned to the non-RRS group. In multivariable logistic regression analysis, the RRS group was not associated with in-hospital mortality after orthopedic surgery compared with the non-RRS group (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.80, 1.08; P = 0.350). However, the RRS group was associated with a 14% lower postoperative complication rate after orthopedic surgery than the non-RRS group (OR 0.86, 95% CI 0.84, 0.86; P < 0.001). CONCLUSIONS: The RRS was not associated with in-hospital mortality following orthopedic surgery in South Korea. However, RRS deployment was related to a decreased risk of postoperative complications in patients undergoing orthopedic surgery.

Oral Extrusion of a Screw After Anterior Cervical Spine Plating: A Case Report.

Although anterior cervical discectomy and fusion (ACDF) is one of the most common surgical procedures performed for the treatment of cervical disease, it is associated with a variety of postoperative complications. Esophageal perforation is a rare but very serious post-ACDF complication, and cases in which screws extrude through the mouth are even rarer. Herein, we present the case of a 61-year-old woman who visited our emergency center with oral extrusion of a screw 6 months after undergoing ACDF. Although diagnostic imaging did not confirm esophageal perforation, the oral extrusion of the screw was clear evidence of the complication. To the best of our knowledge, this is the first reported case of oral screw extrusion without confirmed esophageal injury. This case suggests that screw migration and esophageal perforation can occur depending on the patient's underlying condition, and if the symptoms are mild, conservative treatment alone may be sufficient to treat the perforation.

Why do patients stay in hospital after enhanced recovery thoracoscopic wedge resection? A prospective observational study.

OBJECTIVES: This single-centre prospective observational study aimed to investigate reasons for prolonged hospitalization (over the median length of stay [LOS]) after enhanced recovery thoracoscopic (ERAS 3-port VATS) wedge resection. METHODS: All patients were evaluated twice daily by an investigator for reasons of hospitalization. Each reason was analysed individually. Predictors for prolonged hospitalization were identified using a multivariable backward stepwise logistic regression model. RESULTS: A total of 150 consecutive patients (lymphadenectomy 8.7%) were included from November 2022 to December 2023, with a median LOS of 1 (interquartile range 1-2) day. Of these, 55 patients (36.7%) experienced prolonged hospitalization. The main reasons included postoperative pain (16.0%), air leak (14.7%), and social factors (14.7%), followed by oxygen dependency (7.3%), gastrointestinal factors (5.3%), urinary factors (4.7%), pneumonia (1.3%), pleural effusion (1.3%), chylothorax (0.7%), atrial fibrillation (0.7%), confusion (0.7%), and fatigue (0.7%). Multivariable analysis revealed that an increase in percentage of predicted forced expiratory volume in 1 second (FEV1%pre) by 1% (odds ratio [OR] 0.41, P = 0.023) and percentage of predicted diffusing capacity for carbon monoxide (DLCO%pre) by 1% (OR 0.95, P = 0.002) decreased likelihood of prolonged hospitalization. Conversely, each additional pack-year (OR 1.01, P = 0.028) and living alone (OR 3.55, P = 0.005) increased the risk of prolonged hospitalization. CONCLUSIONS: Prolonged hospitalization (LOS > 1 day) after ERAS 3-port VATS wedge resection, with 8.7% lymphadenectomy, was mainly due to pain, air leak, and social factors. Smokers with decreased FEV1%pre or DLCO%pre and patient living alone were at increased risk.

Patient sex and use of tranexamic acid in liver transplantation.

Background: Differences in medical treatment between women and men are common and involve out-of-hospital emergency care, the intensity of pain treatment, and the use of antifibrinolytic treatment in emergency trauma patients. If woman and man receive different antifibrinolytic treatment in highly-standardized major transplant surgery is unknown. Methods: We conducted a retrospective cohort study on patients who underwent liver transplantation at Heidelberg University Hospital, Heidelberg, Germany between 2004 and 2017. Logistic regression analyses were performed to determine if sex is associated with the administration of TXA during liver transplantation. Secondary endpoints included venous thrombotic complications, graft failure, mortality, myocardial infarction, hepatic artery thrombosis, and stroke within the first 30 days after liver transplant as well as length of hospital stay and length of intensive care unit stay. Results: Out of 779 patients who underwent liver transplantation, 262 patients received TXA. Female sex was not associated with intraoperative administration of TXA [adjusted OR: 0.929 (95% CI 0.654; 1.320), p = 0.681]. The secondary endpoints graft failure (13.2% vs. 8.4%, women vs. men, p = 0.039), pulmonary embolism (3.4% vs. 0.9%, women vs. men, p = 0.012), stroke (1.7% vs. 0.4%, women vs. men, p = 0.049), and deep vein thrombosis (0.8% vs. 0%, women vs. men, p = 0.031) within 30 days after liver transplantation were more frequent in women. Mortality, myocardial infarction, and other secondary endpoints did not differ between groups. However, in women, the use of TXA was associated with a lower rate in thromboembolic complications. Conclusion: Our data indicate that different from other scenarios with massive bleeding complications the administration of TXA during liver transplantation is not associated with sex. However, sex is associated with the risk for complications, and in woman TXA might have a preventive effect on the rate of thromboembolic complications. Reasons underlying the observed sex bias rate remain uncertain.

Early non-compliance to ERAS in gynecological open surgery for malignancies, and post-operative complications: a multicenter, prospective, observational, cohort study.

BACKGROUND: Open surgical procedures for gynecological malignancies have a potential risk of post-operative complications and hence prolonged hospitalization, despite adherence to an Enhanced Recovery After Surgery (ERAS) protocol. PRIMARY OBJECTIVE: To investigate the relationship between non-compliance to an ERAS protocol in the post-operative setting and the rate of post-operative complications, in women who underwent open surgery for gynecological malignancies. STUDY HYPOTHESIS: Early non-compliance with the ERAS protocol increases the risk of post-operative complications. TRIAL DESIGN: Multicenter, prospective, observational, cohort study. MAJOR INCLUSION CRITERIA: Patients with histologically proven gynecological cancer (endometrial, uterine, tubo-ovarian, and cervical) undergoing elective open surgery and managed according to ERAS guidelines. EXCLUSION CRITERIA: Patients with post-operative recovery in an intensive care unit, undergoing anterior or total pelvic exenteration or intraperitoneal chemotherapy. Previous radiotherapy or previous non-gynecological major abdominal surgery. PRIMARY ENDPOINT: Association of non-compliance with the ERAS protocol using five selected indicators on post-operative day 2 with the rate of 30-day post-operative complications. SAMPLE SIZE: 600 patients will be enrolled in the study. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: At present, 106 patients have been recruited. Based on this, the accrual should be completed in 2025. Results should be presented at the end of 2025. TRIAL REGISTRATION: NCT05738902.

The Effects and Risk Factors of Femoral Neck Shortening after Internal Fixation of Femoral Neck Fractures.

Backgroud: Internal fixation has been established as a treatment of choice in relatively young patients with femoral neck fractures. Due to the characteristics of femoral neck anatomy and blood supply, complications such as malunion, nonunion, avascular necrosis, and femoral neck shortening can occur after internal fixation of femoral neck fractures. Unlike other complications such as avascular necrosis or nonunion, femoral neck shortening has not been relatively well studied. This study aimed to investigate the risk factors and clinical outcomes of femoral neck shortening after internal fixation of femoral neck fractures. Methods: From June 2012 to July 2022, among 102 patients who underwent internal fixation of femoral neck fractures, 94 patients who met inclusion and exclusion criteria were retrospectively analyzed. Internal fixation of the femoral neck was done with cannulated compression screws or a femoral neck system. Patients were divided into 2 groups; femoral neck shortening (≥ 5 mm) and no shortening (< 5 mm) according to measurement on follow-up hip anteroposterior (AP) simple radiographs compared with postoperative hip AP simple radiographs. Demographic and radiographic data were compared between the 2 groups. The modified Harris Hip Score (mHHS) and a visual analog scale (VAS) were used to evaluate the clinical outcomes. Results: Among 94 patients, femoral neck shortening was observed in 33 (35.1%). In chi-square test, Pauwels angle, Garden type III or IV (displacement), and cortical comminution were significantly correlated with neck shortening (p < 0.05). In the multifactorial logistic regression test, cortical comminution was significantly correlated with femoral neck shortening (p < 0.01). The shortening group showed significantly lower clinical scores in terms of mHHS and VAS (p < 0.01). Conclusions: The femoral neck shortening group showed significantly lower clinical scores of mHHS and VAS than the no-shortening group. The presence of cortical comminution in preoperative hip computed tomography is a risk factor of femoral neck shortening after internal fixation of femoral neck fractures.

Iatrogenic Brachial Artery Injury During Long Proximal Humeral Interlocking System (PHILOS) Plating.

Iatrogenic vascular injuries are rare but potentially serious complications that can occur during orthopedic procedures involving the proximal humerus. We present a case report of a patient who sustained a brachial artery injury during a long Proximal Humeral Interlocking System (PHILOS) plating procedure for a proximal humeral fracture. A 62-year-old female patient with a left humerus proximal 1/3 shaft fracture underwent open reduction and internal fixation with a long PHILOS plate. During the procedure, difficulty was encountered in achieving adequate plate positioning due to osteoporotic bone and fracture comminution. Upon insertion of a distal second last screw, brisk brachial artery bleeding was encountered. Immediate hemostasis measures were taken, and a plastic surgeon was consulted. The brachial artery injury was identified and repaired with a cephalic vein graft harvested and flushed. Postoperatively, the patient developed median nerve neuropraxia. This case highlights the risk of iatrogenic brachial artery injury during left humerus proximal 1/3 shaft fracture fixation, especially in cases with technical challenges due to osteoporotic bone or comminution. Prompt recognition, involvement of vascular surgery, and appropriate management are crucial in mitigating potential devastating consequences. Associated neurological complications, such as nerve injuries, can also occur and should be monitored. Meticulous surgical technique, anatomical awareness, and vigilant monitoring are essential to minimize the risk of vascular and neurological complications during these procedures. Iatrogenic brachial artery injury is a rare but potentially serious complication of humerus proximal 1/3 shaft fracture. Early recognition, multidisciplinary involvement, and appropriate management strategies are crucial in optimizing patient outcomes and preventing long-term morbidity.

Influence of preoperative HbA1c levels on the occurrence of postoperative complications in patients undergoing coronary artery bypass grafting.

OBJECTIVE: To explore the impact of preoperative HbA1c levels on postoperative complications in coronary heart disease patients undergoing coronary artery bypass grafting (CABG). METHODS: From September 2020 to November 2022, 98 patients with coronary heart disease who were preparing to receive CABG treatment in a cardiac surgery department of a certain hospital were included in the study using the retrospective analysis. According to the preoperative serum hemoglobin A1C (HbA1c) test results, patients were divided into a low-level group (HbA1c < 5.7%, 20 cases), a medium level group (HbA1c: 5.7% ~ 7.0%, 59 cases), and a high level group (> 7%, 19 cases). The surgical outcomes and postoperative complications among the three groups were compared. RESULTS: There was no statistically significant difference in the number of bypass grafts, mechanical ventilation time, and hospitalization time among the three groups of patients (P > 0.05). The high-level group stayed in the ICU longer than the other two groups, while the middle level group had a longer stay than the low-level group (P < 0.05). Within one year of postoperative follow-up, the occurrence of postoperative complications was 20.00%, 32.20%, and 47.37%, respectively, with no statistically significant difference (P > 0.05). Among them, the incidence of acute kidney injury in the high-level group was higher than that in the other groups (P < 0.05), but the correlation difference between the middle and low level groups is P > 0.05. The incidence of infection in the middle level group was higher than that in the low level group (P < 0.05), but the incidence of infection in the high and low level groups was P > 0.05 compared to the medium level group. CONCLUSION: For patients with coronary heart disease undergoing CABG, the higher the preoperative HbA1c level, the longer their postoperative stay in the ICU, and the higher the risk of acute renal function damage.

Association between postoperative complications and hospital length of stay: a large-scale observational study of 4,495,582 patients in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) registry.

BACKGROUND: Precise estimates of risk-adjusted increases in postoperative length of stay (LOS) associated with postoperative complications across a range of complications and operations are not available in the existing literature. METHODS: Associations between preoperative characteristics, postoperative complications and postoperative LOS were tested using medians, interquartile ranges, and nonparametric rank sum tests in a retrospective cohort study using the 2005-2018 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) dataset. A negative binomial model was used with postoperative LOS as the dependent variable and preoperative characteristics and postoperative complications as independent variables. The model was applied to estimate each patient's postoperative LOS with and without each postoperative complication to measure the association between each complication and risk-adjusted change in postoperative LOS. RESULTS: A total of 4,495,582 patients were included. After risk-adjustment, occurrence of each postoperative complication was associated with significantly increased postoperative LOS (between + 3.9 and + 20.1 days, p < 0.0001). The longest risk-adjusted postoperative LOS increases were associated with prolonged ventilator use (+ 20.1 days), wound disruption (+ 19.4 days), and acute renal failure (+ 17.1 days). CONCLUSION: Occurrence of any postoperative complication was associated with increased risk-adjusted postoperative LOS. Degree of increase varied by complication. These data could be useful for patient counseling, allocation of resources, discharge planning, and quality improvement efforts.
