RESUMEN

BACKGROUND: Delirium is a common and potentially serious complication after major surgery. A previous history of depression is a known risk factor for experiencing delirium in patients admitted to the hospital, but the generalised risk has not been estimated in surgical patients. METHODS: We conducted a systematic review and meta-analysis of studies reporting the incidence or relative risk (or relative odds) of delirium in the immediate postoperative period for adults with pre-operative depression. We included studies that defined depression as either a formal pre-existing diagnosis or having clinically important depressive symptoms measured using a patient-reported instrument before surgery. Multilevel random effects meta-analyses were used to estimate the pooled incidences and pooled relative risks. We also conducted subgroup analyses by various study-level characteristics to identify important moderators of pooled estimates. RESULTS: Forty-two studies (n = 4,664,051) from five continents were included. The pooled incidence of postoperative delirium for patients with pre-operative depression was 29% (95%CI 17-43%, I2 = 99.0%), compared with 15% (95%CI 6-28%, I2 = 99.8%) in patients without pre-operative depression and 21% (95% CI 11-33%, I2 = 99.8%) in the cohorts overall. For patients with pre-operative depression, the risk of delirium was 1.91 times greater (95%CI 1.68-2.17, I2 = 42.0%) compared with patients without pre-operative depression. CONCLUSIONS: Patients with a previous diagnosis of depression or clinically important depressive symptoms before surgery have substantially greater risk of experiencing delirium after surgery. Clinicians and patients should be informed of these increased risks. Robust screening and other risk mitigation strategies for postoperative delirium are warranted, especially for patients with pre-operative depression.

RESUMEN

BACKGROUND: Combined pre-operative bowel preparation with oral antibiotics (OAB) and mechanical bowel preparation (MBP) is the current recommendation for elective colorectal surgery. Few have studied racial disparities in bowel preparation and subsequent post-operative complications. METHODS: This retrospective cohort study used 2015-2021 ACS-NSQIP-targeted data for elective colectomy for colon cancer. Multivariate regression evaluated predictors of post-operative outcomes: post-operative ileus, anastomotic leak, surgical site infection (SSI), operative time, and hospital length of stay (LOS). RESULTS: 72,886 patients were evaluated with 82.1% White, 11.1% Black, and 6.8% Asian or Asian Pacific Islander (AAPI); 4.2% were Hispanic and 51.4% male. Regression accounting for age, sex, ASA classification, comorbidities, and operative approach showed Black, AAPI, and Hispanic patients were more likely to have had no bowel preparation compared to White patients receiving MBP+OAB. Compared to White patients, Black and AAPI patients had higher odds of prolonged LOS and pro-longed operative time. Black patients had higher odds of post-operative ileus. CONCLUSIONS: Racial disparities exist in both bowel preparation administration and post-operative complications despite the method of bowel preparation. This warrants exploration into discriminatory bowel preparation practices and potential differences in the efficacy of bowel preparation in specific populations due to biological or social differences, which may affect outcomes. Our study is limited by its use of a large database that lacks socioeconomic variables and patient data beyond 30 days.

RESUMEN

STUDY DESIGN: Systematic Review. OBJECTIVES: To evaluate which cervical deformity correction technique between anterior cervical discectomy and fusion (ACDF) and anterior cervical corpectomy and fusion (ACCF) produces better clinical, radiographic, and operative outcomes. METHODS: We conducted a meta-analysis comparing studies involving ACDF and ACCF. Adult patients with either original or previously treated cervical spine deformities were included. Two independent reviewers categorized extracted data into clinical, radiographic, and operative outcomes, including complications. Clinical assessments included patient-reported outcomes; radiographic evaluations examined C2-C7 Cobb angle, T1 slope, T1-CL, C2-7 SVA, and graft stability. Surgical measures included surgery duration, blood loss, hospital stay, and complications. RESULTS: 26 studies (25727 patients) met inclusion criteria and were extracted. Of these, 14 studies (19077 patients) with low risk of bias were included in meta-analysis. ACDF and ACCF similarly improve clinical outcomes in terms of JOA and NDI, but ACDF is significantly better at achieving lower VAS neck scores. ACDF is also more advantageous for improving cervical lordosis and minimizing the incidence of graft complications. While there is no significant difference between approaches for most surgical complications, ACDF is favorable for reducing operative time, intraoperative blood loss, and length of hospital stay. CONCLUSIONS: While both techniques benefit cervical deformity patients, when both techniques are feasible, ACDF may be superior with respect to VAS neck scores, cervical lordosis, graft complications and certain perioperative outcomes. Further studies are recommended to address outcome variability and refine surgical approach selection.

RESUMEN

BACKGROUND: N-Acetylcysteine (NAC) is a recognized antioxidative agent that facilitates the conjugation of toxic metabolites. In recent years, NAC has been routinely used to limit ischaemia-reperfusion injury in liver transplantation. There remains, however, contradictory evidence on its effectiveness in liver resection. This meta-analysis examines the effectiveness of NAC in improving outcomes following hepatectomy. METHODS: A comprehensive search of the MEDLINE, EMBASE, and Cochrane databases was performed to identify relevant randomized controlled trials (RCTs) published since database inception until November 2023. The outcomes of Day 1 biochemical markers (lactate, ALT, bilirubin, and INR), length of stay, transfusion rates, and morbidity were extracted. Quantitative pooling of data was based on a random-effects model. The study protocol was registered on PROSPERO (Registration no: CRD42023442429). RESULTS: Five RCTs reporting on 388 patients undergoing hepatectomy were included in the analysis. There were no significant differences in patient demographics between groups. Post-operative lactate was lower in patients receiving NAC (WMD -0.61, 95% CI -1.19 to -0.04, I2 = 67%). There were, however, no differences in the post-operative INR (WMD -0.04, 95% CI -0.19 to 0.12, I2 = 96%) and ALT (WMD -94.94, 95% CI -228.46 to 40.38; I2 = 67%). More importantly, there were no statistically significant differences in length of stay, transfusion rates, and morbidity between the two groups. CONCLUSION: The administration of NAC in liver resection did not alter important biochemical parameters suggesting any real effectiveness in reducing hepatic dysfunction. There were no improvements in the clinical outcomes of length of stay, transfusion rates, and overall morbidity.

RESUMEN

BACKGROUND: The modality of thoracoabdominal aortic repair (TAAR) is mainly based on left heart bypass (LHB) in western countries, while in our team, it is mainly based on a unique technique, normothermic iliac perfusion, and there is a lack of systematic reports and long-term results. To describe the operative technique and summarize the patient characteristics and outcomes of TAAR with normothermic iliac perfusion in our team in the last decade. Meanwhile, to explore the influence of different previous surgical history on prognosis. METHODS: 137 consecutive patients who received TAAR with normothermic iliac perfusionby single surgeon from 2012 to 2022 were retrospectively analyzed. Operative details were described and data were grouped according to previous surgical history. Early operative mortality and adverse events were summarized. Survival over time was estimated by the Kaplan-Meier curve. RESULTS: The average age of the cohort was 42.39 ± 11.76 years old, 70.07% were male. 63 (46%) patients had no previous surgery, 53 (39%) patients had total arch replacement with frozen elephant trunk (TAR_FET), and 21 (15%) patients had thoracic endovascular aortic repair (TEVAR). Operative mortality was 4.38%, the incidence of early paraplegia was 6.57%, and previous surgery had no significant effect on prognosis (p = .294). Cumulative survival was 92.1% at 3 years and 90.8% at 5 years. CONCLUSIONS: The normothermic iliac perfusionfor TAAR is feasible regardless of previous surgery, as long as there are no complicating factors. And the early outcomes are satisfactory and the long-term outcomes are reliable.

RESUMEN

INTRODUCTION: Major colorectal surgery is associated with 20 to 40% reduction in physiological and functional capacity and higher level of fatigue 6 to 8 weeks after surgery. The primary aim of this study was to analyse the effects of a multimodal prehabilitation program in colorectal cancer patients to improve functional capacity. The secondary outcome was to evaluate postoperative complications and length of postoperative hospital stay as well as to determine the costs of implementation and indirect costs. METHODS: A single centre, single-blind, randomized controlled trial was conducted. Patients of age > 18 years undergoing elective colorectal resection for colonic cancer were eligible. Exclusion criteria were metastatic disease, severe walking impairments, renal failure stage > 2, ASA score > 3, preoperative chemo-radiation therapy. Patients have been randomized either to prehabilitation intervention groups, receiving 4-week trimodal prehabilitation (physical exercise and nutritional and psychological support) or to control receiving no prehabilitation. Both groups followed enhanced recovery programs and received rehabilitation accordingly. The primary outcome for functional capacity was measured by the 6-Minute Walking Test (6MWT) 4 and 8 weeks after surgery; to evaluate post-operative complications the Clavien-Dindo classification was used. RESULTS: An interim analysis of 71 patients undergoing colorectal surgery was performed, with 35 assigned to interventional arm and 36 to control arm. Baseline characteristics were comparable in both groups. The prehabilitation group showed a significant increase in mean 6MWT distance pre-operatively compared to the control group, with an increase of 96 m (523 ± 24.6 vs. 427 ± 25.3, p = 0.01). At 4 and 8 weeks, the prehabilitation group maintained significant improvements, with an increase of 103 m (514 ± 89 vs. 411 ± 115, p = 0.003) and 90 m (531 ± 82 vs. 441 ± 107, p = 0.008), respectively. There were no statistical significant differences in post-operative complications and hospital length of stay between the two groups. CONCLUSIONS: The preliminary results of this study indicate that it is feasible to implement a prehabilitation protocol lasting approximately 4 weeks. This protocol appears to yield a significant improvement in the physical performance of patients with colon cancer undergoing elective colorectal resection at 4 and 8 weeks after surgery.

RESUMEN

Routine pre-Fontan cardiac catheterization remains standard practice at most centres. However, with advances in non-invasive risk assessment, an invasive haemodynamic assessment may not be necessary for all patients.Using retrospective data from patients undergoing Fontan palliation at our institution, we developed a multivariable model to predict the likelihood of a composite adverse post-operative outcome including prolonged length of stay ≥ 30 days, hospital readmission within 6 months, and death and/or transplant within 6 months. Our baseline model included non-invasive risk factors obtained from clinical history and echocardiogram. We then incrementally incorporated invasive haemodynamic data to determine if these variables improved risk prediction.Our baseline model correctly predicted favourable versus adverse post-Fontan outcomes in 118/174 (68%) patients. Covariates associated with adverse outcomes included the presence of a systemic right ventricle (adjusted adds ratio [aOR] 2.9; 95% CI 1.4, 5.8; p = 0.004), earlier surgical era (aOR 3.1 for era 1 vs 2; 95% CI 1.5, 6.5; p = 0.002), and performance of concomitant surgical procedures at the time of Fontan surgery (aOR 2.5; 95% CI 1.1, 5.0; p = 0.026). Incremental addition of invasively acquired haemodynamic data did not improve model performance or percentage of outcomes predicted.Invasively acquired haemodynamic data does not add substantially to non-invasive risk stratification in the majority of patients. Pre-Fontan catheterization may still be beneficial for angiographic evaluation of anatomy, for therapeutic intervention, and in select patients with equivocal risk stratification.

RESUMEN

Background: Colorectal surgery in patients with inflammatory bowel disease (IBD) and cirrhosis has increased morbidity, which may preclude surgery. Preoperative transjugular intrahepatic portosystemic shunt (TIPS) is postulated to reduce surgical risk. In this retrospective single-center study, we characterized perioperative outcomes in patients with IBD and cirrhosis who underwent preoperative TIPS. Methods: We identified patients with IBD and cirrhosis who had undergone preoperative TIPS for portal decompression between 2010 and 2023. All other indications for TIPS led to patient exclusion. Demographic and medical data were collected, including portal pressure measurements. Primary outcome of interest was perioperative outcomes. Results: Ten patients met the inclusion criteria. The most common surgical indications were dysplasia (50%) and refractory IBD (50%). TIPS was performed at a median of 47 days (IQR 34-80) before surgery, with reduction in portal pressures (22.5 vs. 18.5 mmHg, P < .01) and portosystemic gradient (12.5 vs. 5.5 mmHg, P < .01). Perioperative complications occurred in 80% of patients, including surgical site bleeding (30%), wound dehiscence (10%), systemic infection (30%), liver function elevation (50%), and coagulopathy (50%). No patients required re-operation, with median length of stay being 7 days (IQR 5.5-9.3). The 30-day readmission rate was 40%, most commonly for infection (75%), with 2 patients having intra-abdominal abscesses and 1 patient with concern for bowel ischemia. Ninety-day and one-year survival was 100% and 90%, respectively. Patients with primary sclerosing cholangitis (PSC)-cirrhosis were noted to have higher perioperative morbidity and a 30-day readmission rate. Conclusions: In patients with IBD and cirrhosis, preoperative TIPS facilitated successful surgical intervention despite heightened risk. Nevertheless, significant complications were noted, in particular for patients with PSC-cirrhosis.

RESUMEN

BACKGROUND: To evaluate outcomes of low with high intraabdominal pressure during laparoscopic colorectal resection surgery. METHODS: A systematic search of multiple electronic data sources was conducted, and all studies comparing low with high (standard) intraabdominal pressures were included. Our primary outcomes were post-operative ileus occurrence and return of bowel movement/flatus. The evaluated secondary outcomes included: total operative time, post-operative haemorrhage, anastomotic leak, pneumonia, surgical site infection, overall post-operative complications (categorised by Clavien-Dindo grading), and length of hospital stay. Revman 5.4 was used for data analysis. RESULTS: Six randomised controlled trials (RCTs) and one observational study with a total of 771 patients (370 surgery at low intraabdominal pressure and 401 at high pressures) were included. There was no statistically significant difference in all the measured outcomes; post-operative ileus [OR 0.80; CI (0.42, 1.52), P = 0.50], time-to-pass flatus [OR -4.31; CI (-12.12, 3.50), P = 0.28], total operative time [OR 0.40; CI (-10.19, 11.00), P = 0.94], post-operative haemorrhage [OR 1.51; CI (0.41, 5.58, P = 0.53], anastomotic leak [OR 1.14; CI (0.26, 4.91), P = 0.86], pneumonia [OR 1.15; CI (0.22, 6.09), P = 0.87], SSI [OR 0.69; CI (0.19, 2.47), P = 0.57], overall post-operative complications [OR 0.82; CI (0.52, 1.30), P = 0.40], Clavien-Dindo grade ≥ 3 [OR 1.27; CI (0.59, 2.77), P = 0.54], and length of hospital stay [OR -0.68; CI (-1.61, 0.24), P = 0.15]. CONCLUSION: Low intraabdominal pressure is safe and feasible approach to laparoscopic colorectal resection surgery with non-inferior outcomes to standard or high pressures. More robust and well-powered RCTs are needed to consolidate the potential benefits of low over high pressure intra-abdominal surgery.

RESUMEN

The use of cannabis as a method of chronic pain relief has skyrocketed since its legalization in states across the United States. Clinicians currently have a limited scope regarding the effectiveness of marijuana on surgical procedures. This systematic review aims to determine the effect of current cannabis use on the rate of failure of spinal fusions and overall surgical outcomes. A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. PubMed, Embase, and Scopus were searched, identifying studies assessing spinal fusion with reported preoperative cannabis use. Outcomes of interest included reoperation due to fusion failure or pseudoarthrosis with a follow-up time of at least six months. Subgroups of cervical fusions alone and lumbar fusions alone were also analyzed. Certainty in evidence and bias was assessed using the GRADE criteria and ROBINS-I tool (PROSPERO #CRD42023463548). Four studies met the inclusion criteria, with a total of 788 patients (188 in the cannabis user group and 600 in the non-user group). The rate of revision surgery among cannabis users was higher than that in non-users for all spinal fusions (RR: 3.58, 95% CI: 1.67 to 7.66, p = 0.001). For cervical fusions alone, there remained a higher rate of revision surgery for cannabis users compared to non-users (RR: 4.47, 95% CI: 1.93 to 10.36, p = 0.0005). For lumbar fusions alone, there was no difference in the rates of revision surgery between cannabis users and non-users (RR: 1.21, 95% CI: 0.28 to 7.73, p = 0.79). Cannabis use was shown to be associated with a higher rate of pseudoarthrosis revisions in spinal fusions on meta-analysis. On subgroup stratification by spine region, cannabis use remained associated with pseudoarthrosis revisions on cervical fusions alone but not lumbar fusions alone. Further research with larger, randomized studies is required to fully elucidate the relationship between cannabis use and fusion, both in general and by spinal region.

RESUMEN

BACKGROUND: Total knee arthroplasty (TKA) is considered the gold standard treatment for patients who have advanced hemophilic knee arthropathy. However, special considerations are required for these patients. This prospective study reports on the need for soft-tissue procedures, implant types, complication rates, mean 53.3 months implant survivorship, and patient-reported outcome measures of TKA in hemophilic patients. METHODS: There were twenty primary TKAs that were performed on 15 hemophilic patients from 2012 to 2023. The mean follow-up was 53.3 months (range, 6 to 128). The necessity for additional soft tissue procedures, implant type, complications, and revision rates were recorded. Knee Injury and Osteoarthritis Outcome Score, Knee Society Score, Hemophilia-specific Quality of Life Questionnaire for Adults, Hemophilia Activities List, and range of motion, were compared preoperatively and at the last follow-up. RESULTS: At the last follow-up, implant survivorship was 90%. There were 2 revisions: one for aseptic loosening and one for periprosthetic joint infection. Additional soft tissue procedures included 2 quadriceps snips (10%). Tibial augments, tibial stubby stems, and both tibial and femoral traditional stems were used in one (5%), 4 (20%), and one (5%) TKAs, respectively. A constrained posterior-stabilized bearing was necessary in one case. Clinically and statistically significant improvements were found between the preoperative and final follow-up values of all patient-reported outcome measures, knee flexion (73 versus 108 °, P < 0.001), and flexion contracture (11 versus 4 °, P = 0.002). CONCLUSIONS: This study showed that TKA, in patients who have hemophilic knee arthropathy, is a reliable treatment option that improves knee function and patients' quality of life with acceptable implant survival rates at midterm follow-up (mean 53.3 months). Standard implants and approaches can be used in most cases. Despite good outcomes, hemophilic patients carry additional risks for complications that require specific considerations. It is paramount for these patients to be treated in specialized centers by experienced surgeons to achieve good results.

RESUMEN

PURPOSE: Currently no guidance exists within the literature regarding diagnostic criteria or the long-term outcomes for paediatric patients with acute compartment syndrome (ACS). We conducted a retrospective cohort study reviewing all cases of paediatric ACS managed at a single tertiary referral centre with the aim of characterising the factors responsible for the eventual outcomes. METHODS: The patient cohort was identified retrospectively by interrogating the hospital coding system for all paediatric patients between January 2014 and November 2022. The electronic emergency department, inpatient and operative notes as well as clinic letters for each patient were reviewed and data collected regarding presentation, associated injuries, management and subsequent complications plus length of follow-up. The data was analysed to determine if differences in presentation or management affected long term outcome. RESULTS: The final cohort consisted of 34 patients with a mean age of ten years at the time of presentation. The mean time from presentation to fasciotomy was 27.6 h (range 3.0 - 66.6). There was an overall complication rate of 37.5% with a mean follow-up period of 21 months. Patients who had direct closure of their fasciotomy wounds had a significantly lower complications rate and fewer operations compared to those who healed via other wound coverage methods or secondary intention (p < 0.05). CONCLUSIONS: Significantly higher complication rates were observed in patients who were unable to have direct wound closure following emergency fasciotomy. This information may be utilised to rationalise long term treatment plans and in counselling of patients and parents.

RESUMEN

OBJECTIVES: Hypermetabolism is associated with clinical prognosis of cancer patients. The aim of this study was to explore the association between basal metabolic rate (BMR) and postoperative clinical outcomes in gastric cancer patients. METHODS: We collected data of 958 gastric cancer patients admitted at our center from June 2014 to December 2018. The optimal cutoff value of BMR (BMR ≤1149 kcal/day) was obtained using the X-tile plot. Logistic and Cox regression analyses were then performed to evaluate the relevant influencing factors of clinical outcomes. Finally, R software was utilized to construct the nomogram. RESULTS: A total of 213 patients were defined as having a lower basal metabolic rate (LBMR). Univariate and multivariate analyses showed that gastric cancer patients with LBMR were more prone to postoperative complications and had poor long-term overall survival (OS). The established nomogram had good predictive power to assess the risk of OS in gastric cancer patients after radical gastrectomy (c-index was 0.764). CONCLUSIONS: Overall, LBMR on admission is associated with the occurrence of postoperative complications in gastric cancer patients, and this population has a poorer long-term survival. Therefore, there should be more focus on the perioperative management of patients with this risk factor before surgery.

RESUMEN

BACKGROUND AND METHODS: Pancreatico-duodenectomy (PD) carries significant morbidity and mortality, with very few modifiable risk factors. Radiological evidence of sarcopenia is associated with poor outcomes. This retrospective study aimed to analyse the relationship between easy-to-use bedside nutritional assessment techniques and radiological markers of muscle loss to identify those patients most likely to benefit from prehabilitation. RESULTS: Data were available in 184 consecutive patients undergoing PD. Malnutrition was present in 33-71%, and 48% had a high visceral fat-to-skeletal muscle ratio, suggestive of sarcopenic obesity (SO). Surgical risk was higher in patients with obesity (OR 1.07, 95%CI 1.01-1.14, p = 0.031), and length of stay was 5 days longer in those with SO (p = 0.006). There was no correlation between skeletal muscle and malnutrition using percentage weight loss or the malnutrition universal screening tool (MUST), but a weak correlation between the highest hand grip strength (HGS; 0.468, p < 0.001) and the Global Leadership in Malnutrition (GLIM) criteria (-0.379, p < 0.001). CONCLUSIONS: Nutritional assessment tools give widely variable results. Further research is needed to identify patients at significant nutritional risk prior to PD. In the meantime, those with malnutrition (according to the GLIM criteria), obesity or low HGS should be referred to prehabilitation.

RESUMEN

We conducted a systematic review to examine perioperative outcomes for adults undergoing minimally invasive Roux-en-Y gastric bypass (RYGB) with and without concurrent cholecystectomy (CCE). We reviewed the literature using OVID MEDLINE(R), Embase, Cochrane CENTRAL, Web of Science, and medRxiv and identified studies published between 1946 and May 2023. We identified a total of 2402 studies with 11 included in the final analysis (combined 149,356 patients). Studies suggested increased operative time associated with RYGB-CCE, with mixed results regarding length of stay and rates of bile duct injury. Presently available data is not robust enough to conclude whether minimally invasive RYGB with CCE harms or benefits patients compared to RYGB alone.

RESUMEN

OBJECTIVE: As the population ages, vascular surgeons are treating progressively older, multimorbid patients at risk of peri-operative complications. An embedded physician has been shown to improve outcomes in general and orthopaedic surgery. This systematic review and meta-analysis aimed to investigate the impact of surgeon-physician co-management models on morbidity and mortality rates in vascular inpatients. DATA SOURCES: PubMed, Scopus, Embase, conference abstract listings, and clinical trial registries. REVIEW METHODS: Studies comparing adult vascular surgery inpatients under co-management with standard of care were eligible. The relative risks (RRs) of death, medical complications, and 30 day re-admission between co-management and standard care were calculated. The effect of co-management on the mean length of stay was calculated using weighted means. Risk of bias was assessed using the Methodological Index for Non-Randomised Studies, and certainty assessment with the GRADE analysis tools. RESULTS: No randomised controlled trials were identified. Eight single institution studies between 2011 and 2020 with 7 410 patients were included. All studies were observational using before-after methodology. Studies were of high to moderate risk of bias, and outcomes were of very low GRADE certainty of evidence. Co-management was associated with a statistically significant lower relative risk of death (RR 0.64, 95% confidence interval [CI] 0.44 - 0.92; p = .02), cardiac complications (RR 0.47, 95% CI 0.25 - 0.87; p = .02), and infective complications (RR 0.49, 95% CI 0.35 - 0.67; p < .001) in vascular inpatients. No statistically significant differences in length of stay (standard mean difference -0.6 days, 95% CI -1.44 - 0.24 days; p = .16) and 30 day re-admission (RR 0.96, 95% CI 0.84 - 1.08; p = .49) were noted. CONCLUSION: Early results of physician and surgeon co-management for vascular surgery inpatients showed promising results from very low certainty data. Further well designed, prospective studies are needed to determine how to maximise the impact of physicians within a vascular service to improve patient outcomes while using hospital resources effectively.

RESUMEN

OBJECTIVE: To compare the peri-operative outcomes of radical prostatectomy (RP) for locally advanced, node-positive, and metastatic prostate cancer (PCa), as determined through pathological staging, using the American College of Surgeons National Surgical Quality Improvement Project. METHODS: We identified RP procedures performed between 2019 and 2021. Patients were stratified by pathological staging to compare the effect of locally advanced disease (T3-4), node positivity (N+) and metastasis (M+) vs localised PCa (T1-2 N0 M0). Baseline demographics and 30-day outcomes, including operating time, length of hospital stay (LOS), 30-day mortality, readmissions, reoperations, major complications, minor complications and surgery-specific complications, were compared between groups. RESULTS: Pathological staging data were available for 9276 RPs. Baseline demographics were comparable. There was a slightly higher rate of minor complications in the locally advanced cohort, but no significant difference in major complications, 30-day mortality, readmissions, or rectal injuries. Node positivity was associated with longer operating time, LOS, and some slightly increased rates of 30-day complications. RP in patients with metastatic disease appeared to be similarly safe to RP in patients with M0 disease, although it was associated with a longer LOS and slightly increased rates of certain complications. CONCLUSIONS: For patients with pathologically determined locally advanced, node-positive, and metastatic PCa, RP appears to be safe, and is not associated with significantly higher rates of 30-day mortality or major complications compared to RP for localised PCa. This study adds to the growing body of literature investigating the role of RP for advanced PCa; further studies are needed to better characterise the risks and benefits of surgery in such patients.

RESUMEN

BACKGROUND: This study aimed to characterize changes in patient demographics and outcomes for same-day discharge total hip arthroplasty (THA) over a 10-year period at a single orthopaedic specialty hospital. METHODS: A consecutive series of 1,654 patients between 2013 and 2022 who underwent unilateral THA and were discharged on the same calendar day were retrospectively reviewed. Patient demographics, including age, sex, body mass index (BMI), age-adjusted Charlson Comorbidity Index, and American Society of Anesthesiologists (ASA), were collected. Readmissions, complications, and unplanned visits were recorded for 90 days postoperatively. In order to compare the demographics of patients over time, patients were divided into 3 groups: Time Group A (2013 to 2016), Time Group B (2017 to 2019), and Time Group C (2020 to 2022). RESULTS: The mean age, BMI, ASA score, and CCI increased significantly across each time group. Age increased from 57 years (range, 23 to 77) to 60 years (range, 20 to 87). The BMI increased from 28.1 (range, 18 to 41) to 29.4 (range, 18 to 47). The percentage of patients aged > 70 years almost doubled over time, as did the percentage of patients who had a BMI > 35. Overall complications increased from 3.44 to 6.82%, reflective of the changing health status of patients. Readmissions increased from 0.57 to 1.70% over time. Despite this, there were no readmissions for any patient within the first 24 hours of surgery. CONCLUSIONS: Our study has 3 important findings. We identified a worsening patient demographic over time with an increasing percentage of patients of advanced age and higher BMI, ASA, and age-adjusted Charlson Comorbidity Index. Also, there was also an increase in readmissions, complications, and unplanned visits. In addition, despite this worsening patient demographic, there were no readmissions within 24 hours and a low rate of readmissions or unplanned visits within the first 48 hours across all time periods, suggesting that same-day discharge-THA continues to be safe in properly selected patients.

RESUMEN

INTRODUCTION: Ankylosing Spondylitis (AS) patients with acute spinal fractures represent a challenge for practicing spine surgeons due to difficult operative anatomy and susceptibility to complications. RESEARCH QUESTION: Does intraoperative CT-navigation improve outcomes in patients with ankylosing spondylitis undergoing surgery? METHODS: A retrospective review was carried out at our centre from 05/2016-06/2021 to identify AS patients presenting with a traumatic spinal fracture, managed surgically with posterior spinal fusion (PSF). Cohorts were categorised and compared for outcomes based on those who underwent PSF with intraoperative CT-navigation versus those surgically managed with traditional intraoperative fluoroscopy. RESULTS: 37 AS patients were identified. 29/37 (78.4%) underwent PSF. Intraoperative navigation was used in 14 (48.3%) cases. Mean age of the entire cohort was 67.6 years. No difference existed between the navigated and non-navigated groups for mean levels fused (5.35 vs 5.07; p â€‹= â€‹0.31), length of operation (217.9mins vs 175.3mins; p â€‹= â€‹0.07), overall length-of-stay (12 days vs 21.9 days; p â€‹= â€‹0.16), patients requiring HDU (3/14 vs 5/15; p â€‹= â€‹0.09) or ICU (5/14 vs 9/15; p â€‹= â€‹0.10), postoperative neurological improvement (1/14 vs 1/15; p â€‹= â€‹0.48) or deterioration (1/14 vs 0/15; p â€‹= â€‹0.15), intraoperative complications (2/14 vs 3/15; p â€‹= â€‹0.34), postoperative complications 4/14 vs 4/15; p â€‹= â€‹0.46), revision surgeries (3/14 vs 1/15; p â€‹= â€‹0.16) and 30-day mortality (0/14 vs 0/15). CONCLUSION: This is the first study that compares surgical outcomes of navigated vs non-navigated PSFs for AS patients with an acute spinal fracture. Although limited by its retrospective design and sample size, this study highlights the non-inferiority of intraoperative navigation as a surgical aid in a challenging cohort.

RESUMEN

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European AAOCA Registry (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres. METHODS: EURO-AAOCA is a prospective, multicentre registry including 13 European centres. Herein, we evaluated differences in clinical presentations and management, treatment decisions and surgical outcomes across centres from January 2019 to June 2023. RESULTS: A total of 262 AAOCA patients were included, with a median age of 33 years (12-53) with a bimodal distribution. One hundred thirty-nine (53.1%) were symptomatic, whereas chest pain (n = 74, 53.2%) was the most common complaint, followed by syncope (n = 21, 15.1%). Seven (5%) patients presented with a myocardial infarction, 2 (1.4%) with aborted sudden cardiac death. Right-AAOCA was most frequent (150, 57.5%), followed by left-AAOCA in 51 (19.5%), and circumflex AAOCA in 20 (7.7%). There were significant differences regarding diagnostics between age groups and across centres. Seventy-four (28.2%) patients underwent surgery with no operative deaths; minor postoperative complications occurred in 10 (3.8%) cases. CONCLUSIONS: Currently, no uniform agreement exists among European centres with regard to diagnostic protocols and clinical management for AAOCA variants. Although surgery is a safe procedure in AAOCA, future longitudinal outcome data will hopefully shed light on how to best decide towards optimal selection of patients undergoing revascularization versus conservative treatment.
