Teaching and Practicing Congenital Hand Surgery in Cambodia - Lessons Learnt.

The global burden of surgical conditions is becoming increasingly prevalent in the developing world. Hand surgery, in particular congenital hand surgery, presents with its own challenges, particularly the unique skill sets needed, multidisciplinary nature and heterogeneity of cases. The aim of this review article is to present our experience of practising congenital hand surgery in Cambodia, and to explore the feasibility of teaching this specialty in developing countries within a meaningful and sustainable framework. Since 2013, a group of hand surgeons and therapists have visited the Children Surgical Centre in Cambodia. A community-oriented curriculum was developed following the initial visits, with analysis of data and local surgeon's skill sets. These were further refined using the Pareto analysis and selected competency procedures to develop entrustable professional activities (EPAs). Common paediatric hand cases were identified and taught to the local surgeons. Essential elements of this model include the need for measurable outcomes, clear curriculum goals, long-term partnerships and information technology support.

Opioid Use Following Spine Surgery in Ambulatory Surgical Centers Versus Hospital Outpatient Departments.

Retrospective cohort study. To assess the association between undergoing spine surgery in an ambulatory surgical center (ASC) vs a hospital outpatient department (HOPD) and (a) perioperative opioid prescription patterns and (b) prolonged opioid use. Data from the Merative MarketScan Database included patients aged 18-64 who underwent single-level or multilevel anterior cervical discectomy and fusion (ACDF) or lumbar decompression between January 2017 and June 2021. Primary outcomes included receipt of a perioperative opioid prescription, perioperative oral morphine milligram equivalents (MMEs), and prolonged opioid use (defined as opioid prescription 91-180days post-surgery). Secondary outcomes included the number of perioperative opioid prescriptions filled (single/multiple) and type of initial perioperative opioid filled (potent/weak). Analysis of prolonged opioid use was limited to opioid-naive patients. Propensity score matching (1 ASC to 3 HOPD cases) and logistic regression models were used for analysis. The study included 11,654 ACDF and 26,486 lumbar decompression patients. For ACDF, ASCs had higher odds of an initial potent opioid prescription (OR = 1.18, 95% CI 1.08-1.30, P < .001) and higher total adjusted mean MMEs (+21.14, 95% CI 3.08-39.20, P = .02). For lumbar decompression, ASCs had increased odds of an initial potent opioid (OR = 1.23, 95% CI 1.16-1.30, P < .001) but lower odds of multiple opioid prescriptions (OR = 0.90, 95% CI 0.85-0.96, P < .001). There was no significant association between the surgery setting and prolonged opioid use. Differences in perioperative opioid prescribing were observed between ASCs and HOPDs, but there was no increase in prolonged opioid use in ASCs. Further research is needed to optimize postoperative pain management in different outpatient settings.

DYNAMICS OF MORPHOFUNCTIONAL PARAMETERS OF RESISTANT DIABETIC MACULAR EDEMA AFTER SURGICAL TREATMENT

Anti-angiogenic injections are currently established as the «gold standard» for treating diabetic macular edema (DME). Vitreoretinal surgery is indicated in cases involving an epiretinal membrane or vitreoretinal traction syndrome. Some physicians consider it feasible to perform vitrectomy with the removal of the internal limiting membrane in patients with this condition.The objective of this study is to assess changes in the morphofunctional parameters of the retina in patients with resistant forms of DME who have undergone surgical intervention. At the N.I. Pirogov National Medical and Surgical Center, 75 patients diagnosed with DME unresponsive to conservative therapy (anti-vascular proliferation therapy, retinal laser coagulation) were operated on. All patients were divided into three groups based on the type of intervention.Evaluation of best-corrected visual acuity after surgery revealed a statistically significant improvement in this parameter among patients in the second and third groups compared to those in the first group six months post-operation. Patients in the third group showed a notable reduction in retinal thickness in the foveal area one month after the intervention. A significant decrease in edema was observed in patients from the second and third groups compared to those in the first group over the period from one month to one year. When assessing light sensitivity, a significant improvement in parameters was noted in patients from the second and third groups compared to the data from the first group one week after the surgery.The results confirm the high effectiveness of vitreoretinal surgical intervention in patients with resistant diabetic macular edema, affirming the possibility of selecting a surgical approach.

AHP SO06 - A case report of the nutritional and multi-disciplinary team (MDT) management of an emergency oesophageal perforation associated with Eosinophilic Oesophagitis (EOE)

Abstract Background EOE once considered rare, is a chronic inflammatory condition of the oesophagus presenting as dysphagia and food impaction in children and adults. Awareness and management of EOE is variable despite an increasing prevalence and the condition deemed the most common cause of oesophageal perforation in adults and children by the British Society of Gastroenterology (BSG). This case review aims to increase the awareness of EOE, highlight the clinical presentation of EOE, discuss considerations for the nutritional management and the importance of an MDT approach to the care of this condition in relation to the BSG consensus guidelines. Method The patient was admitted to a specialist oesophago-gastric surgical centre in the Northwest of England. A retrospective review of the patient’s case notes was completed. This included exploration of all inpatient and outpatient contacts stored in the electronic patient records system. Results 18-year-old underweight male with IgE-mediated nut allergy and odynophagia, developed complex multi-site oesophageal perforations following OGD. Management included 40-day endoluminal vacuum therapy and extensive nutritional support. Although initial biopsies lacked diagnostic quality and conclusive results, EOE was subsequently confirmed. Dietetic evaluation included nutritional status, atopic history, symptoms, and dietary intolerances. MDT discussions influenced care continuity and patient compliance. Feeding delays attributable to frequent theatre visits impacted continued weight loss; addressed with allergen-free enteral and parenteral feeding, and dietary reintroduction, following six-food elimination once perforations had healed. Healthy BMI was achieved through patient’s preferred long-term management of normal diet and Budesonide. Conclusion Increased awareness of EOE is paramount for patients presenting with unexplained oesophageal perforation. Obtaining biopsy samples as per BSG guidance supports earlier diagnosis and management plan. A thorough clinical history including childhood eating behaviours, atopic history, dietary intolerances and symptom presentation from the patient and relatives gathers collateral information to support diagnosis and treatment planning. Joint discussions regarding pharmaceutical management, dietary elimination and reintroduction are important to achieve remission. The case highlights the importance of collaborative MDT working with the surgical, medical and dietetics whilst empowering the patient to make informed decisions regarding the nutritional and medical management of condition.

Cardiovascular surgery and the importance of dental consultation

Introduction: A health system is based on meeting the needs of the population, which presents cultural and social differences when defining these needs and health-related problems and when using available health care services.Methods: A bibliographic review was conducted using the terms "health system", "dental consultation", "cardiovascular surgery" to search databases.Development: Valve surgery involves a comprehensive patient care process that covers from the request to leaving the surgical center, with the aim of providing information, comfort and safety. This process includes several phases such as surgical indication and presurgical evaluation, whose purpose is to identify risk factors and optimize perioperative care to reduce morbidity and mortality.Conclusions: The oral cavity can contribute to the development of pathologies such as caries and periodontal disease, which are risk factors for cardiovascular conditions. Infective endocarditis (IE), a bacterial infection of the heart valves, may be associated with oral foci in 10-20% of cases. For this reason, organizations such as the American Heart Association recommend dental consultation before valve surgery to minimize risks.

Experience of using robot-assisted (da Vinci) operations in the treatment of common endometriosis

Background. Currently, genital endometriosis is considered as one of the most severe conditions in women of reproductive age, which has detrimental consequences for social, professional and psychological functioning. It ranks third in the structure of gynecological diseases after inflammatory diseases of the female reproductive system and uterine fibroids. Because of this, it acquires a more pronounced social significance and ceases to be only a medical problem. Aim. To study the results of surgical treatment of patients with severe forms of genital endometriosis using the da Vinci surgical robotic complex.Materials and methods. A retrospective analysis of the treatment results of 51 patients operated on at the N.I. Pirogov National Medical and Surgical Center for the period from January 2015 to July 2024, who underwent robot-assisted (da Vinci) operations for deep endometriosis involving neighboring organs. The duration of surgery and hospital stay, the amount of blood loss, the frequency of intra- and postoperative complications, the clinical course of the disease in the long-term postoperative period, the frequency of detection of residual infiltration in the postoperative period, and the implementation of reproductive plans were analyzed.Results. The duration of the surgical intervention was 220.8 ± 21.87 minutes. The postoperative bed-day was 6.9 ± 1.5 bed days. The average blood loss was 160.2 ± 67.58 ml. There were no intraoperative complications. Postoperative complications accounted for 7.8 %. Residual infiltration occurred in 11.7 % of cases. 94.1 % of the patients had no clinical symptoms of endometriosis in the long-term postoperative period. The pregnancy rate was 31.9 %.Conclusion. Surgical treatment of deep endometriosis using da Vinci surgical robotic complex in the amount of radical removal of endometrioid infiltrate has a positive effect on both the clinical course of the disease and the reproductive potential of a woman. Real-time fluorescence navigation has demonstrated additional imaging capabilities in robotic surgery for deep endometriosis, potentially increasing the radicalism of surgical treatment of infiltrating endometriosis and may lead to a reduction in recurrence rates.

Outpatient versus inpatient total shoulder arthroplasty: A meta-analysis of clinical outcomes and adverse events.

In recent years, orthopaedic procedures have increasingly shifted from inpatient to outpatient settings. This trend includes total shoulder arthroplasty (TSA), which is being performed more frequently in outpatient facilities and ambulatory surgical centres. The purpose of this study was to compare the clinical outcomes and rates of adverse events between outpatient and inpatient TSA. PubMed, Cochrane, and Google Scholar (pages 1-20) databases were screened for articles comparing outpatient to inpatient TSA through June 2024, using relevant and holistic search terms. Non-comparative articles and those utilizing national databases were excluded from our study. Data on complications, myocardial infarction (MI), thromboembolic events, anaemia/transfusions, infections, readmissions, emergency department (ED) visits, revision surgery, and patient reported outcome measures at one year (Visual Analog Scale [VAS] and American Shoulder and Elbow Surgeons [ASES] score) were extracted. A total of 14 articles were included in our study, involving 1070 outpatient and 1330 inpatient TSA patients. Patients in the inpatient group were older and had a higher ASA compared to the patients in the outpatient group. The outpatient TSA group was found to have significantly lower rates of overall complications (odds ratio [OR] = 0.59, p = 0.001), medical complications (OR = 0.43, p < 0.001), and readmissions (OR = 0.47, p = 0.008), as well as higher mean ASES scores (81.4 vs. 78.5, p = 0.01) when compared to the inpatient TSA group. There were no significant differences in rates of ED visits (p = 0.27), revisions (p = 0.06), and VAS scores (p = 0.15) between inpatient and outpatient TSA groups. TSAs performed in the outpatient setting had a lower rate of overall adverse events, medical complications, readmissions, and a higher ASES score compared to inpatient TSAs. However, since patients in the inpatient group had higher ASA and were older, our results support the safety of the outpatient TSA based on the current selection criteria.

Safety of thyroidectomy as day care surgery at a rural setting in Eastern Uganda.

The practice of day care surgery is less embraced in many low-middle-income countries (LMIC), and even less for some procedures considered major such as thyroidectomy. Here we examine the safety of day care thyroidectomy at Kyabirwa Surgical Center, a stand-alone day care surgery center in rural Eastern Uganda. This was a retrospective cohort study conducted between 2019 and 2023. All patients who had day care thyroidectomy were included. Demographics, diagnosis, investigation findings, pathology reports, and surgery outcomes were collected. Postoperative follow-up data up to 30days were also collected. Data were analyzed using R version 4.3.2. A total of 51 patients underwent same-day thyroidectomy, with an average age of 44.9±12.1years and 98% female. Procedures included total thyroidectomy (5, 9.8%), subtotal thyroidectomy (26, 51.0%), and lobectomy (20, 39.2%). Average size of the glands was 7.9±2.21cm. The majority 46 (90.2%) were of benign pathology. All patients were discharged by the evening of the same day. Complications encountered included hypocalcemia (1), hypertrophic scar (1), seroma (2), and transient recurrentlaryngeal nerve injury (1). Overall complications rate was 9.8%. Gland size was statistically significant between patients with no complications (7.68±2.06cm) versus complications (9.90±2.82, p<0.05). With overall low complication rates, these findings suggest that thyroidectomy can safely be performed on a day care basis in a rural LMIC setting with suboptimal health care delivery.

Mental Health Status Of Nursing Professionals Working In The Surgical Center

Background: In Brazil, nursing professionals, including Nurses, Nursing Technicians, and Nursing Assistants, represent the majority of healthcare workers. As of April 2024, there are over 2 million nursing professionals registered in the country. These workers face increasing stress levels, with mental disorders related to work activities now accounting for 30% of global mental health issues. Nursing professionals in surgical centers provide critical psychological support to patients, offering comfort, stress relief, and care throughout the surgical process. This proposal aims to conduct a literature review to assess the mental health of nurses working in surgical blocks. Materials and Methods: This research is a Systematic Literature Review focused on the mental health of nursing professionals in the surgical block, analyzing studies from the past five years. Searches were conducted in databases like LILACS, MEDLINE, and Scopus, using specific inclusion and exclusion criteria. Articles were selected based on relevance, and data from these studies were extracted and critically evaluated. Results: This study reviewed seven articles on mental health issues among nurses in surgical centers, identifying stressors like work overload, lack of resources, and emotional strain. Key factors include poor work environment, long shifts, and insufficient support. Findings emphasize the need for better staffing, improved management, and emotional support to reduce burnout. The research advocates for structural interventions to improve nurses' well-being and patient safety. Conclusion: Stress and mental illness among nurses in surgical centers are influenced by organizational factors and workload. The review highlights the urgent need for interventions to improve their mental health and hospital efficiency

Optimizing pediatric tonsillectomy outcomes with an opioid sparing anesthesia protocol: Learning and continuously improving with real-world data.

This quality improvement initiative is a continued pursuit to optimize outcomes by iteratively improving our opioid sparing anesthesia protocol for tonsillectomy with or without adenoidectomy at our pediatric ambulatory surgical center through data driven Plan-Do-Study-Act cycles. From 1/2015 through 12/2023, our standardized tonsillectomy protocol underwent nine procedure-specific perioperative Plan-Do-Study-Act cycles, three procedure-specific postoperative prescription Plan-Do-Study-Act cycles, and four general ambulatory surgical center enhanced recovery Plan-Do-Study-Act cycles. We analyzed data from the medical record using statistical process control charts. The primary outcome measure was the percent of patients requiring intravenous opioid in the post anesthesia care unit. Secondary outcomes included maximum post anesthesia care unit pain score, the percent of patients requiring treatment for nausea and/or vomiting in the post anesthesia care unit, and the number of postoperative opioid prescription dosages. Balancing measures were average post anesthesia care unit length of stay, percent of patients with prolonged Post Anesthesia Care Unit length of stay (>120 min), and 30-day reoperation rate. A total of 5654 tonsillectomy with or without adenoidectomy cases were performed at our ambulatory surgical center from 2015 to 2023. The incidence of intravenous opioid administered in the post anesthesia care unit initially rose with opioid free anesthesia launch, but subsequently decreased below the target of 10%. Maximum post anesthesia care unit pain scores rose from mean 3.6 to 4.5, but subsequently returned to the baseline of 3.5, while the incidence of postoperative nausea and/or vomiting improved. The average post anesthesia care unit length of stay increased by 10 min with opioid free anesthesia; however, prolonged post anesthesia care unit stay and 30-day reoperation rates were unchanged. The continued refinement of our opioid sparing anesthesia protocol has led to reduced perioperative and home opioid use, stable maximum post anesthesia care unit pain scores, and improved postoperative nausea and vomiting rates, with only a slight increase in mean post anesthesia care unit length of stay.

Long-term results of carotid body tumours surgery and predictive analytics on metastatic disease and recurrence.

The determination of clinico-surgical predictors of carotid body tumour (CBT) metastasizing and/or recurrence. Patients with CBT but without a history of its previous treatment who had received inpatient medical aid at a tertiary surgical centre during the period 2011-2021 were retrospectively reviewed to obtain baseline data. Primary endpoints of the study were CBT metastasizing and/or local recurrence after radical surgery (composite endpoint) and overall survival. Secondary endpoint of the study was primary patency of carotid arteries that had been repaired/reconstructed as a result of CBT removal. Suspected predictors of CBT metastasizing/recurrence were young age of CBT onset, positive family history, multifocal paraganglioma, Shamblin type III CBT, carotid bifurcation and/or internal carotid artery (ICA) reconstruction as a result of CBT excision. To detect CBT metastasizing/recurrence, prospective imaging-based whole-body screening was suggested to patients. Fifty-three patients met the eligibility criteria. The overall survival rate was 100% at a median follow-up time of 68 months (interquartile range [IQR] 27‒104.5 months). The primary patency of repaired carotid arteries (n = 9) was 88.9% at a median follow-up time of 99 months (IQR 15.5‒116.5 months). Thirty-nine patients underwent the prospective whole-body screening. Eight (20.5%) patients were diagnosed with metastatic disease (n = 6) or local recurrence (n = 2). Patients with CBT metastasizing/recurrence were younger at age of CBT onset (p = .011), more frequently had Shamblin type III CBT (p = .004) and the necessity for carotid artery repair/reconstruction (p = .041) than patients without metastasizing/recurrence. These two groups were similar in terms of gender (p = .682), the prevalence of multifocal paraganglioma (p = .167) and positive family history (p = .180). Only the belonging of a CBT to Shamblin type III was defined as a statistically significant predictor of CBT metastasizing/recurrence in both univariable and multivariable binary logistic regression analyses (odds ratio 30; 95% confidence interval: 2.649-339.739; p = .006 and odds ratio 75.409; 95% confidence interval: 1.082-5254.557; p = .046, respectively). Multifocal paraganglioma as a predictor exhibited a strong tendency towards statistical significance (p = .09 and p = .072, respectively). Other suspected predictors didn't reach the level of statistical significance either in univariable (p = .151 for positive family history) or in multivariable (p = .211 for age of CBT onset; p = .734 for carotid artery reconstruction/repair) binary logistic regression analyses. Shamblin type III CBT has high potential for metastasizing and recurrence. Patients with Shamblin type III CBT and/or multifocal paraganglioma should be considered for genetic testing as well as preoperative whole-body radiological imaging and long-term postoperative whole-body imaging-based follow-up.

A Retrospective Analysis of Emergency Versus Elective Surgical Outcomes in Colon Cancer Patients: A Single-Center Study.

Introduction: Emergency surgical interventions for colon cancer are often associated with poorer outcomes compared to elective surgeries due to the advanced state of the disease and the urgency of intervention. This retrospective study aimed to evaluate the management of emergency management of colon cancer and to evaluate differences in patient outcomes. Conducted at a single surgical emergency center, the study analyzed 182 cases, focusing on demographics, tumor characteristics, surgical methods and patient outcomes. Material and Methods: A retrospective observational study was conducted, involving 182 cases who underwent surgery for colon cancer in a single surgical emergency center. Data was collected from hospital records, encompassing demographic details, tumor characteristics, surgical intervention detail and outcomes, alongside with inflammatory profiles. Statistical analyses included descriptive statistics and t-tests with standard significance at p < 0.05. Results: The study showed that emergency cases had significantly poorer in-hospital survival rates (75.42%) compared to elective surgeries. Inflammatory markers such as Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio were higher in emergency cases, suggesting heightened systemic stress. Emergency surgery was also associated with a higher incidence of ostomy and postoperative complications. Conclusions: Emergency surgery for colon cancer is linked to more advanced tumors, increased physiological stress and lesser clinical outcomes. Early detection strategies and active targeted screening could reduce the need for emergency interventions. Future research should focus on early diagnosis protocols and enhancing public health strategies to minimize emergency presentations, thereby leading to better outcomes for colon cancer patients.

Lifestyle Recommendations for Patients Before and After Thoracic Aortic Surgery: A Framework Analysis

Abstract Background Patients receive many different recommendations after thoracic aortic surgery. Unfortunately, there is much variation in recommendations between different surgical centers. This variation in recommendations creates uncertainty and anxiety in patients. Therefore, we aimed to provide an overview with clear lifestyle recommendations for patients before and after thoracic aortic surgery. Methods Documentary research and a framework analysis were used to analyze brochures, website texts, and health care protocols. These documents consisted of lifestyle recommendations for patients before and after thoracic aortic surgery (direct information) or cardiac surgery (indirect information). An analytical framework was constructed and all lifestyle recommendations for patients before and after thoracic aortic surgery were coded through indexing, charting, and mapping by two researchers (N.K. and H.v.Z.). The first draft with lifestyle recommendations was prepared by two researchers (N.K. and H.v.Z.). Feedback from all authors involved patients and consulted health care professionals was processed in the final draft. Results In total, 170 documents were analyzed. Indexing revealed 414 lifestyle recommendations, which were included in the first draft. Charting, mapping, removal of duplicates, and processing of feedback resulted in a final draft with 52 lifestyle recommendations about behavioral change, body weight, nutrition, cessation of alcohol and drug use, cessation of smoking, wound healing, sedentary behavior and physical activity, mental well-being, and family and close relatives. Conclusion This study provides an overview of clear lifestyle recommendations for patients before and after thoracic aortic surgery. This overview is the first step because follow-up research is needed on which lifestyle recommendations are necessary and evidence-based. The overview of lifestyle recommendations serves as a foundation, after which individual customization can be provided.

Chest Wall Hydatid Disease: Surgical management and risk Factors for Recurrence and Mortality

Background Hydatidosis of the thoracic wall differs from other hydatid localizations in its pathophysiology, diagnostic, and therapeutic management. It is a little-studied entity. The objectives of our work were to describe its surgical management and to analyze the factors that may influence recurrence and mortality. Methods A retrospective, descriptive, longitudinal, and multicenter study on four university hospital surgical centers of Tunis, from January 1995 to December 2022 including operated hydatid cysts of the thoracic wall. Overall survival (OS) and cumulative recurrence rates were calculated. Univariate and multivariable Cox regression analyses were performed to identify recurrence and mortality risk factors. Results Forty-nine patients were included. The mean age was 41 ± 17 years [8-76]. The main presenting sign was thoracic parietal swelling (n=22). Chest ultrasound and CT scan showed multivesicular formation in 17 and 33 cases, respectively. Muscle involvement was in the intercostal (n=4), paravertebral (n=13), and pectoralis major (n=3) muscles. Bone involvement was vertebral (n=11), costal (n=12), costo-vertebral (n=21) and sternal (n=2). A posterolateral thoracotomy was performed (n=20). Surgical excision at various levels of the chest wall with spinal stabilization (n=15) was performed. Sixty-three percent of the patients received antiparasitic medical treatment. Recurrence occurred in 37% of cases. Four patients died from hydatidosis-related complications. Factors could be independently associated with recurrence such as male gender, and vertebral involvement. The presence of a visceral hydatid cyst located at a distance from the parietal lesion at the time of diagnosis and the occurrence of postoperative infectious complications could increase mortality. Conclusions Chest wall hydatidosis represents a rare medical condition where surgery remains the preferred treatment modality. However, it carries a substantial burden of morbidity and mortality, influenced by various factors. Further large-scale studies are necessary to gain a deeper understanding of these factors and to optimize management strategies accordingly.

Intraoperative Cost Comparison of Endoscopic Carpal Tunnel Release With WALANT Versus MAC Anesthesia.

The cost of endoscopic carpal tunnel release (ECTR) has historically been shown to be significantly higher than the cost of open carpal tunnel release (OCTR). Setting and anesthetic technique drive costs in hand surgery; ambulatory surgical center (ASC) settings demonstrate lower costs when compared to hospital-based settings and local-only anesthetic techniques demonstrate savings over general anesthesia. The purpose of this study is to compare wide awake local-only anesthesia technique (WALANT) to monitored anesthetic care (MAC) for ECTR performed in an ASC setting. This study includes 481 ECTR under WALANT and 405 ECTR under MAC, performed between January 2019 and December 2021 in an ASC. Utilizing previously reported direct operating room costs, overhead, and material costs, we calculated a final cost for each procedure. We also report our complication rates: intraoperative conversion to OCTR and late revision to OCTR. Intraoperative times were shortest for ECTR performed under WALANT (22 min) versus ECTR under MAC (25 min). The total cost for ECTR under WALANT was most cost-effective at $1341.28 versus ECTR under MAC at $1634.00. Both techniques demonstrated a low complication profile. Our intraoperative process flow, staffing model, and ASC setting resulted in cost savings making ECTR an economically feasible option.

The Waiting 4 Surgery study: burden of in-hospital care

Abstract Introduction Patients with coronary artery and valvular diseases with surgical indication represent a significant proportion of hospitalizations. The Waiting 4 Surgery study (W4S) aims to better study this group of patients, their burden of hospital care and identify those with event-free admissions. Purpose In this work, we analyze both the economical and hospital-care burden of this group of patients. Methods Retrospective study of consecutive patients admitted between 2019 and 2021 with coronary artery and/or aortic valve diseases waiting for coronary artery bypass graft (CABG), aortic valve replacement (AVR; surgical or percutaneous) or both. Total admission time and the cost associated with the hospitalization were analyzed. For event-free hospitalization, the following events were considered: death, re-infarction, cardiac pulmonary arrest (CPA), stroke, ventricular tachycardia, acute heart failure (AHF), rest chest pain and reintroduction of intravenous (IV) drugs. We performed a secondary cost analysis for patients with event-free hospitalization after the first 5 days of admission. Results Total of 184 patients were included, mean age 67.9 years, 70.1% male, 71.2% submitted to CABG and 20.7% to AVR (6.5% to both). During admission 23.9% of patients reintroduced IV drugs, 20.1% had chest pain, 5.4% had AHF and 2.2% had CPA. No deaths, strokes of re-infarctions were observed. The total time of hospitalization was 3 259 patients/days, representing an occupation rate of 18.6% and a total cost of 1 898 447€ (10 318€/patient and 632 816€/year). Mean admission time was 17.6 days. Total cost for CABG and AVR patients was 1 479 613€ and 594 562€, respectively. Total of 115 patients had an event-free hospitalization (62.5%). The total time of event-free hospitalization was 1 650 patients/days, representing an occupation rate of 9.42% and a total cost of 979 710€ (6 575€/patient and 326 570€/year). Mean event-free admission time was 14.3 days. Total cost for CABG and AVR in event-free patients was 863 155€ and 223 258€, respectively. Conclusion The W4S study demonstrates the impact patients waiting for surgery represent in hospital care: a very high economic and logistic burden. The majority of patients showed an event-free admission, and identifying such patients for early discharge and ambulatory management together with surgical centers should be a priority.

Using Atrial Fibrillation Burden Trends and Machine Learning to Predict Near-Term Risk of Cardiovascular Hospitalization.

Atrial fibrillation is associated with an increased risk of cardiovascular hospitalization (CVH), which may be triggered by changes in daily burden. Machine learning of dynamic trends in atrial fibrillation burden, as measured by insertable cardiac monitors (ICMs), may be useful in predicting near-term CVH. Using Optum's deidentified Clinformatics Data Mart Database (2007-2019), linked with the Medtronic CareLink ICM database, we identified patients with >1 days of ICM-detected atrial fibrillation. ICM-detected diagnostic parameters were transformed into simple moving averages over different periods for daily follow-up. A diagnostic trend was defined as the comparison of 2 simple moving averages of different periods for each diagnostic parameter. CVH was defined as any hospital, emergency department, or ambulatory surgical center encounter with a cardiovascular diagnosis-related group or diagnosis code. Machine learning was used to determine which diagnostic trends could best predict patient risk 5 days before CVH. A total of 2616 patients with ICMs met the inclusion criteria (71±11 years; 55% male). Among them, 1998 (76%) had a planned or unplanned CVH over 605 363 days. Machine learning revealed distinct groups: (A) sinus rhythm (reference), (B) below-average burden, (C) above-average burden, and (D) above-average burden with decreasing patient activity. The relative risk was increased in all groups versus the reference (B, 4.49 [95% CI, 3.74-5.40]; C, 8.41 [95% CI, 7.00-10.11]; D, 11.15 [95% CI, 9.10-13.65]), including a 21% increase in CVH detection over prespecified burden thresholds of duration (≥1 hour) and quantity (≥5%). The area under the receiver operating characteristic curve increased from 0.55 when using hourly burden amounts to 0.66 when using burden trends and decreasing patient activity (P<0.001), a 20% increase in predictive power. Trends in atrial fibrillation were strongly associated with near-term CVH, especially above-average burden coupled with low patient activity. This approach could provide actionable information to guide treatment and reduce CVH.

Preoperative predictors of difficult early laparoscopic cholecystectomy among patients with acute calculous cholecystitis in Egypt

BackgroundEarly laparoscopic cholecystectomy (ELC) in the setting of acute calculous cholecystitis (ACC) requires to be performed by highly-skilled surgeons to avoid complications. The purpose of this study is to identify preoperative factors that would predict difficult ELC among patients with ACC prior to proceeding with surgery.MethodsWe retrospectively reviewed all patients who received ELC within 10 days from the onset of symptoms of ACC between August 1, 2018, and December 31, 2022. They were divided into 2 groups according to the difficulty of surgery.Results149 patients with ACC received ELC during the study period. ELC was considered difficult in 52 patients (35%). Five preoperative factors were identified as significant predictors of difficult ELC (DELC) on multivariate analysis: duration of acute attack ≥ 4 days from the onset of symptoms till surgery (OR 34.4, P < 0.001), ultrasound showing largest gallstone size > 20 mm (OR 20.2, P = 0.029), ultrasound showing gallstone impaction in Hartmann’s pouch (OR 7.2, P = 0.017), history of prior episode(s) of acute attack (OR 6.8, P = 0.048), and diabetes mellitus (OR 5.8, P = 0.046).ConclusionCareful preoperative assessment of patients with ACC is crucial among junior surgeons with limited surgical expertise prior to proceeding with ELC to identify those at risk of DELC to potentially reduce postoperative morbidity and mortality. If encountered, a management plan should be made, and surgery should proceed only upon confirming the availability of experienced surgeons in the field of biliary and laparoscopic surgery to supervise or assist in the procedure. Alternatively, such group of patients should rather be transferred to more advanced surgical centers which offer higher level of care to maintain patient safety and optimal surgical outcomes. More importantly, bail-out procedures should always be resorted to whenever DELC is encountered intraoperatively to prevent further surgical damage.

Ultrasound for infantile midgut malrotation: Techniques, pearls, and pitfalls.

Midgut malrotation with volvulus is a surgical emergency with potentially devastating outcomes which include short gut syndrome necessitating long-term parenteral nutrition, overwhelming sepsis, and death. The clinical presentation is most frequently with bilious vomiting in the first days-weeks of life, which is non-specific and common. Timely imaging investigation is therefore crucial to prevent delays to diagnosis and treatment and avoid unnecessary surgical exploration in infants with non-surgical bilious vomiting. Fluoroscopic upper gastrointestinal contrast series (UGI) has been the first-line imaging modality to investigate midgut malrotation at pediatric surgical centers worldwide. However, there is a growing body of evidence to indicate that ultrasound (US) has greater diagnostic accuracy than UGI in this context. Furthermore, US offers the benefits of accessibility, portability, lack of ionizing radiation, and the ability to identify alternative diagnoses, and is beginning to attract significant attention and consideration in the literature. Over the last 3years, we have transitioned to an "US-first" pathway for the investigation of midgut malrotation in infants with bilious vomiting. This pictorial essay illustrates our comprehensive approach, describes unique troubleshooting techniques, and highlights the variably published pitfalls we have encountered with the aim of encouraging wider adoption.
