EGS SO10 - Restructuring of emergency surgical service in DGH leads to significant reduction in time to cholecystectomy for gallstone pancreatitis in line with international guidance

Abstract Background The International Association of Pancreatology guidelines suggest that patients with mild biliary pancreatitis undergo cholecystectomy during their initial hospital admission. A single-center retrospective study was conducted to examine adherence to this guideline following a significant overhaul of emergency surgical services. Our team, with support from the surgical ambulatory emergency care network, revolutionized care through an Emergency Surgery Unit (EmSU) system. This included surgical assessments with ambulation, coordinated radiology appointments, semi-emergency theatre lists twice a week in addition to NCEPOD theatre sessions, and an emergency roster split by patient gender, ensuring a balanced caseload for the surgeons on duty each week. Method A retrospective study of patients with mild biliary pancreatitis for three years before (n = 107) and after (n=108) the EmSU system. Cholecystectomy on index admission was recorded, as was overall time to surgery (days). Data was analysed using GraphPad Prism Version 9.5.1. Data is expressed as Mean ± SEM. Percentages underwent Arcsine transformation prior to inferential analysis. Groups of data were analysed using Students T-Tests. Results The percentage of patients operated on index admission increased 13.1-fold (4.8% to 62.9%; P < 0.01). Days to surgery saw a 10.1-fold reduction (332.5 ± 41.1 to 32.9 ± 6.3 days; P < 0.0001). Conclusion The adoption of our EmSU system has drastically improved care for patients with gallstone pancreatitis, bringing it much closer to best practice guidance. Further improvement is likely with increased buy-in from all members of staff.

EGS SO32 - Management of Spontaneous Oesophageal Perforations in the era of Endo-Vacuum Therapy- Preliminary Results of a Single-Institution Study

Abstract Background Spontaneous Oesophageal Perforation (SOP) is a rare gastro-intestinal surgical emergency with devastating morbidity and mortality. Given the rarity of the entity, there is no up-to-date evidence on outcomes in the context of centralized esophagogastric services neither consensus guidelines nor standardized treatment algorithms on how these should be optimally managed. Endoscopic Vacuum Therapy (EVT) has emerged as safe and effective option particularly in cases where major invasive surgery would otherwise be deferred. Herein, we sought to explore the effectiveness, patient benefit and related morbidity/mortality by exploring the strategy outcomes in SOPs prior to and during periods where EVT was available. Method A single-centre retrospective cohort study incorporating all consecutive patients (N=72) presented or transferred to our tertiary oesophagogastric unit for SOP management between 01/01/2009-31/12/2023 was undertaken. Patients with anastomotic leak post-surgery or perforation secondary to malignancy, iatrogenic, traumatic or food bolus were excluded. Primary study-outcomes were treatment type including non-operative, EVT after 01/01/2018 or other endoscopic therapy, surgical operation including laparotomy, thoracotomy, primary defect repair or over a T-tube, disconnection with oesophagostomy, stenting or other interventional radiology procedures and their rate of success or failure. Secondary outcomes were length of stay, 90-day complications requiring re-intervention or re-admission, 30-, 90-day, 1-year mortality. Results In 2009-2017 pre-EVT period, 25/72 patients were managed a) 18/25 surgically with thoracotomy and T-tube, b) non-surgical 7/25, four were palliated. 30-day, 90-day mortality were 4/25 and 2/25, 90-day morbidity Clavien-Dindo >IIIa 14/25 (56%), 90-day reintervention 8/25 (32%), median LOS 27 days. In 2018-2023 EVT period , 47/72 patients were treated with a) laparotomy, left thoracotomy, defect repair over t-tube, chest drainage in 18/47, b) non-surgical 15/47, c) endoscopy 6/47, d) EVT in 14/47. 30-day mortality was 6/47, 90-day mortality 2/47, 90-day morbidity Clavien-Dindo >IIIa 32/47 (68%), 90-day reintervention 26/47 (55.3%), median LOS 34 days. 1-year mortality was 5/25 and 3/47 respectively. Conclusion EVT therapy appears to be a feasible additional treatment modality in the management of spontaneous oesophageal perforations. Optimal patient selection, therapeutic endoscopic expertise, knowledge of the technique, multidisciplinary approach and team collaboration are essentials for favourable outcomes. Of note, management of oesophageal perforations in a dedicated UGI centre is directly related to patient outcomes and is recommended as soon as such a diagnosis is confirmed.

EGS SO20 - Management & outcomes from oesophageal perforations at a tertiary centre

Abstract Background Oesophageal perforations, whilst rare, are a challenging surgical emergency. Traditionally associated with high morbidity and mortality, outcomes have progressively improved over the past 25 years, likely due to advances in medical care and specialised management in high volume tertiary centres. This study examines the management strategies and outcomes from oesophageal perforations at our tertiary unit. Method A retrospective cohort analysis was conducted on consecutive emergency cases of thoracic and junctional oesophageal perforations from January 2019 to June 2024. Data on patient demographics, baseline characteristics, management strategies and clinical outcomes were extracted from the patient’s electronic records. Kaplan-Meier survival curves were generated using the management approach and the extent of perforation as the predictive variables. Results 51 patients (mean age 47 years, 66% male) were treated for oesophageal perforations. The predominant aetiology was spontaneous (80%, n=41). Contained perforations were identified in 57% (n=29) of patients based on imaging, endoscopic, or operative findings. Conservative management was applied in 57% (n=29) of cases. Among those requiring intervention, 11 (58%) underwent surgery, while the remainder underwent endoscopical via vacuum therapy (32%, n=6) or stenting (11%, n=2). The mean in-hospital stay was 11 days (IQR 7-29). The 30-day mortality rate was 18% (n=9). Survival analysis revealed improved survival probabilities with contained perforations and non-surgical management strategies (p=0.023 and 0.001 respectively). Conclusion Our results demonstrate that the outcomes from oesophageal perforations continue to improve, reflecting ongoing advancements in therapeutic management. Furthermore, whilst surgery was once the mainstay, there appears to be a safe, increasing shift towards more conservative and endoscopic management.

MS O01 - HPB Outcomes following Cholecystostomy Insertion for Acute Cholecystitis: A National Registry-based Study

Abstract Background Acute cholecystitis (AC) is a commonly encountered surgical emergency. In cases of severe AC or cholangitis, or in patients with significant comorbidities, percutaneous cholecystostomy (PC) may be employed. International data suggest PC is associated with significantly worse patient outcomes, but limited data exist in the Irish context. Method All patients with AC presenting to public hospitals in Ireland between January 2017 and July 2023 were identified using the National Quality Assurance and Improvement System (NQAIS). Data were collected on patient demographics including age, co-morbidities, length of stay/LOS, operative intervention, endoscopic intervention, critical care admissions, in-patient mortality, and readmissions. All patients managed with PC were identified, and their outcomes compared to patients managed without PC. Results In total, 20,886 patients were admitted with AC. 975 (5%) patients underwent PC and 19,911 patients (95%) were managed without percutaneous cholecystostomy. In comparison to non-cholecystostomy cohort, the PC cohort was older (median 72 v 58 years, p<0.001), less likely to be female (39% v 57% p<0.001), had proportionally longer LOS (<0.001), higher mortality rates (<0.001), were more likely to be admitted to critical care (<0.001), and more likely to be re-admitted to hospital within 30 days (<0.001). Conclusion Cholecystostomy insertion occurs in older patients with more comorbidities. These patients have higher in-hospital mortality rates, higher rates of critical care admission, longer LOS, and increased 30-day readmission rates.

Professionalism assessment of students in clinical education through Situational Judgment Test (SJT).

The study aims to assess the situational judgment capability of students in various professions, including medicine, surgical nursing, anesthesia nursing, and emergency medical technology, using a validated and adapted Situational Judgment Test (SJT). The cross-sectional study was conducted at Qom University of Medical Sciences in 2023-2024. The study consisted of two steps: (1) adaptation and validity assessment of the SJT in various health professions, and (2) evaluation of students' situational judgment capability using the adapted SJT. Participants included 207 students from surgical nursing, anesthesia nursing, medicine, and emergency medical technology departments, selected through stratified random sampling. The SJT included 10 constructed-response scenarios developed by Alkhuzaee and colleagues in 2022. The validation and adaptation process utilized consensus methods, and the SJT was modified to a selected response format based on a knowledge-based approach. Scores ranged from 0 to 30. Cohen's method and norm-referencing standard deviation were used to calculate a cut-off score. Data were analyzed using descriptive statistics (frequency, mean, standard deviation) and inferential statistics (independent t-test, ANOVA, and ANCOVA). The face and content validity of the adapted SJT with a selected-response format was confirmed by expert agreement. The reliability of the SJT was approved, with a Cronbach's Alpha of 0.81. The mean score of students' situational judgment in professionalism was 11.90 (SD 4.54). Students' professions significantly impacted their situational judgment scores (F (3.201) = 3.67, p = 0.01, Partial Eta Squared = 0.052). The adaption and validation of SJT with a selected response format were confirmed by experts who evaluated the situational judgment capabilities of students in different clinical professions. The reliability of the SJT was acceptable-Cohen's method as a standard-setting approach assisted in identifying students needing support and training. The moderate level of situational judgment capacity confirmed the development of the educational program for the improvement of non-cognitive and non-technical skills such as judgment and decision-making in the field of professionalism.

Using Deep Learning, Optuna, and Digital Images to Identify Necrotizing Fasciitis

Necrotizing fasciitis, which is categorized as a medical and surgical emergency, is a life-threatening soft tissue infection. Necrotizing fasciitis diagnosis primarily relies on computed tomography (CT), magnetic resonance imaging (MRI), ultrasound scans, surgical biopsy, blood tests, and expert knowledge from doctors or nurses. Necrotizing fasciitis develops rapidly, making early diagnosis crucial. With the rapid progress of information technology and systems, in terms of both hardware and software, deep learning techniques have been employed to address problems in various fields. This study develops an information system using convolutional neural networks (CNNs), Optuna, and digital images (CNNOPTDI) to detect necrotizing fasciitis. The determination of the hyperparameters in convolutional neural networks plays a critical role in influencing classification performance. Therefore, Optuna, an optimization framework for hyperparameter selection, is utilized to optimize the hyperparameters of the CNN models. We collect the images for this study from open data sources such as Open-i and Wikipedia. The numerical results reveal that the developed CNNOPTDI system is feasible and effective in identifying necrotizing fasciitis with very satisfactory classification accuracy. Therefore, a potential future application of the CNNOPTDI system could be in remote medical stations or telemedicine settings to assist with the early detection of necrotizing fasciitis.

Successful pregnancy outcome following selective uterine artery embolization in a case of perforating gestational trophoblastic neoplasia

Gestational trophoblastic neoplasia (GTN) includes a range of premalignant and malignant disorders of trophoblastic tissue. Invasive mole can present as a surgical emergency with rapidly progressive and highly vascular trophoblasts causing uterine perforation. Often hysterectomy is resorted to as a life-saving measure but in women desirous of future fertility, other options should be considered. We present the case of a nulliparous woman who presented with hemoperitoneum following perforating GTN. She was pale with stable vitals. Serum beta hCG at presentation was 98,156IU/L. Ultrasound pelvis revealed a highly vascular heterogenous hypoechoic mass of 5.8cm×5.5cm×6.5cm in the region of fundus and anterior myometrium showing significant internal and peripheral vascularity and displacing endometrium posteriorly. Ultrasound guided tap revealed hemoperitoneum. We decided for uterine artery embolization following clinical stabilization of the patient followed by chemotherapy. Figure 1 shows CT angiography done prior to uterine artery embolization. She conceived spontaneously two years later and was followed up closely in antenatal period. She was induced at 38 completed weeks due to oligohydramnios and decreased fetal movements and vaginally delivered a healthy baby with no postnatal complications. Fertility sparing procedures should be considered as a first possible option in selective cases. Multidisciplinary approach in high-risk cases is a key to optimal outcome.

Common error traps in anesthesia for neonatal surgical emergencies.

Neonatal surgical emergencies are challenging, often high-risk procedures for the pediatric anesthesiologist. Though each emergency presents different anesthetic challenges, several error traps exist that are common to all procedures in this patient population. These error traps include errors in surgical timing, airway management, maintenance of normothermia and normoglycemia, and recognition of pharmacologic and physiologic differences. In this narrative review, we will discuss each error trap to aid the clinician in recognizing, planning for, and mitigating adverse events.

Epidemiology and outcomes of critically ill patients in the emergency department of a tertiary teaching hospital in Rwanda.

The introduction of Emergency Medicine in Rwanda in 2015 has been associated with a mortality reduction in patients presenting to Kigali University Teaching Hospital (KUTH). In the context of increasing numbers of critically ill patients presenting to Emergency Departments (ED) globally, the aim of this study was to describe the characteristics of critically ill patients, the critical care interventions performed, and the outcomes of critically ill patients presenting to the KUTH ED with the goal of informing future research into the root causes of mortality of critically ill ED patients and of identifying high yield topics for didactic and procedural training. A descriptive observational prospective cohort pilot study analyzed all patients ≥15 years who presented to KUTH between April and June 2022 with modified South African Triage Scores of Red with alarm, Red without alarm, and Orange. Of 320 patients, 66.9% were male and median age was 40 years. Patients were triaged as Orange (65.3%), Red without alarm (22.8%), and Red with alarm (11.9%). Presentations were categorized as: medical emergencies (48.0%), traumatic injury (44.5%), and surgical emergencies (7.6%). Median length of stay was 31h (IQR 28, 56) and boarding was 23h (IQR 8, 48). Overall mortality was 12.2% and highest among medical emergencies (16.5%, p = 0.048) and increased significantly with triage color: Red with alarm (47.4%), Red without alarm (16.4%), and Orange (4.3%, p < 0.0001). Cardiopulmonary resuscitation (CPR) (10.3%), endotracheal intubation (8.8%), and vasopressor administration (3.1%) were the most frequent critical interventions performed. Survival after cardiac arrest was 9.1% and 32.1% after intubation. Mortality was associated with the following interventions: CPR, intubation, and use of vasopressors (p < 0.05). This pilot study identified the most common critical care interventions performed and a high mortality among patients who required these interventions in the ED of a tertiary teaching hospital in Rwanda. These findings will inform didactics and procedural training for emergency care providers. Future research should focus on the root causes of mortality in these specific patient populations and identify areas of system strengthening to reduce mortality.

Idiopathic pneumoperitoneum after gynecological surgery: a report of two clinical cases

Abstract Pneumoperitoneum, characterized by the presence of air in the peritoneal cavity, is usually associated with severe clinical conditions, such as perforations of hollow viscera, often requiring urgent surgical intervention. However, in rare cases, pneumoperitoneum occurs without an identifiable cause, thus classified as idiopathic pneumoperitoneum. We present two clinical cases of women who developed pneumoperitoneum after extensive gynecological surgeries. In the first case, a 63-year-old woman underwent elective hysterectomy and bilateral adnexectomy due to a large adnexal mass. In the second case, a 55-year-old woman had a similar surgical history. Both patients were treated conservatively, with a positive outcome. Idiopathic pneumoperitoneum is a diagnostic and therapeutic challenge, especially in the postoperative context. The cases presented underscore the importance of rigorous diagnostic evaluation and a cautious therapeutic approach, suggesting that idiopathic pneumoperitoneum may represent a benign and self-limiting phenomenon rather than a surgical emergency.

028. Traumatic Diaphragmatic Rupture with Unstable Hemodynamic: A Case Report of a Rare Surgical Trauma Emergency

Background: Traumatic diaphragmatic rupture (TDR) with unstable hemodynamics is a life-threatening condition often masked by other injuries, necessitating timely diagnosis and treatment. This case report illustrates the significance of rapid response and resuscitation in managing a 17-year-old female patient with TDR following a severe traffic accident. Case: A 17-year-old female patient was admitted after a motorcycle accident, arriving at the hospital 4 hours and 10 minutes post-incident. She displayed respiratory distress (SpO2: 80% on FM) and severe hemodynamic instability (BP: 70/40 mmHg, HR: 121 bpm). Grade IV traumatic diaphragmatic rupture (AAST) was confirmed alongside multiple injuries. Resuscitation began with intubation, 1 L of crystalloid fluid, and a 1-unit PRC transfusion. Initial management improved her BP to 80/60 mmHg; however, it later dropped to 60/40 mmHg. A FAST Ultrasonography (USG) revealed free echogenic fluid in the hepatorenal space, prompting emergency exploratory laparotomy. Intraoperatively, a diaphragmatic rupture was identified, with herniation of the liver, stomach, and colon. Surgical interventions included diaphragmatic repair and chest tube insertion. Postoperatively, the patient required vasopressors (dobutamine and epinephrine) to stabilize her hemodynamics (BP: 100/60 mmHg, HR: 83 bpm). Conclusion: Early diagnosis and aggressive resuscitation are vital in managing TDR with unstable hemodynamics, underscoring the necessity for rapid assessment and intervention.

Late Phase Testicular Torsion in Pre-Geriatic Age: A Case Report

Background: Testicular torsion is a urological emergency caused by a twist of spermatic cord, which result in testicular tissue ischemia and requiring immediate surgery. The incidence occurred generally in children and adolescents, rarely found in adults. Severe Scrotal pain is the most common manifestation of testicular torsion. The definitive treatment for testicular torsion is surgery, either one of orchidopexy or orchidectomy. The prognosis of testicular torsion depends on the onset of symptoms and the decision time for surgery. Case Report: A 52-year-old man presented to emergency department with a history of gradual severe right-sided scrotal pain (visual analogue scale 8) radiated to the right groin in the last 3 day before admission. Previously, the patient's genitals were hit by the table. On physical examination, the testicles were found to be asymmetrical, swollen, redness, tenderness, and the testicle felt hard and immobilized, either the cremaster reflex or the Phren sign test were negative. The TWIST score was 6 (high risk for testicular torsion). Orchidopexy and orchidectomy were performed immediately without Scrotal Doppler Ultrasonography due to operational problems. Histopathology examination of the orchidectomy specimen impression showed an inflammation sign with exudative fluid presentation. Conclusion: Gradual Severe scrotal pain manifestations should be suspected as testicular torsion as soon as possible before it evolves into later phase. One of the causes of late phase testicular torsion is late admission to Hospital. Surgical emergency action should be taken considering theemergency state without waiting for ideal sonography

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.

Multicenter comparison of non-operative techniques of intussusception reduction: saline versus air versus barium

Purpose: Intussusception is a common pediatric surgical emergency and non-operative reduction is its first line of management. We aimed to compare 3 contemporary techniques of intussusception reduction.Methods: A retrospective study was performed in 3 tertiary care centers in India from January 2017 through December 2019. In the 3 centers, the primary reduction techniques were ultrasound-guided saline reduction (USR), fluoroscopy-guided pneumatic reduction (FPR), and fluoroscopy-guided barium reduction (FBR), respectively. As per these techniques used, we compared clinical characteristics, such as the successful reduction.Results: A total of 255 patients underwent one of the 3 reduction techniques in the study period. Reduction was successful in 90.3%, 85.1%, and 87.7% in the USR, FPR, and FBR groups, respectively (P = 0.961). Mean time to reduction was shorter in the FPR group (30.8 ± 8.9 seconds), compared with the USR (575.0 ± 242.3 seconds) and FBR groups (495.0 ± 118.4 seconds; P &lt; 0.001). Recurrence rates were 11.8%, 20.3%, and 15.8% in the USR, FPR, and FBR groups, respectively (P = 0.522). No association was found between the patients’ age or symptom duration and the successful reduction. One patient in the USR group, 3 in the FPR group, and 4 in the FBR group reported second recurrences. Perforation occurred in 1 patient in the FPR group while no complications occurred in the other groups. There was no in-hospital mortality.Conclusion: All 3 techniques are equally effective, with FPR requiring a shorter time than the other 2 techniques. The reduction technique should be chosen based on the strengths and weaknesses of each technique, as well as local availability.

Colon Cancer With Bladder Invasion: A Single Center Experience.

The aim of our study was to investigate the outcome of colon cancer with bladder invasion after surgical intervention. Between 2011 and 2022, a total of 41 patients diagnosed with colon cancer and bladder invasion underwent surgical procedures at Taichung Veterans General Hospital. The impact of various risk factors on overall survival (OS) was assessed using Kaplan-Meier analyses and Cox proportional hazards models. Among the enrolled patients, 21 underwent radical cystectomy, while 20 underwent partial cystectomy. Twelve had tumors located in the rectum, 19 in the sigmoid colon, and 10 in both the rectum and sigmoid colon. The median OS was 71.8 months in stage 2, 50.8 months in stage 3, and 11.2 months in stage 4 (p=0.061). Median OS was 71.8 months in patients with negative surgical margins and 10.5 months in those with positive surgical margins (p=0.003). In multivariate regression analysis, positive surgical margins [hazard ratio (HR)=3.64, 95% confidence interval (CI)=1.28-10.34, p=0.015] and emergency operations (HR=4.57, 95%CI=1.34-15.55, p=0.015) significantly impacted OS. Complete resection of colon cancer with bladder invasion can yield excellent oncologic outcomes. The decision between partial and radical cystectomy should balance surgical margin clearance and the preservation of quality of life. Both surgical margin involvement and emergency operations are independent risk factors for OS.

Preoperative mortality risk evaluation in abdominal surgical emergencies: development and internal validation of the NDAR score from a national multicenter audit in Senegal

IntroductionAbdominal surgical emergencies have a high mortality rate. Effective management primarily relies on the early identification of patients at high risk of postoperative complications. The objective of our study was to determine the prognostic factors associated with poor outcomes from abdominal surgical emergencies in Senegal and to establish a predictive score for mortality for preoperative risk evaluation (NDAR (New Death Assessment Risk) score).MethodologyThis was a retrospective national cross-sectional study conducted over one year in 14 regions of Senegal. Adult patients (aged > 15 years) who presented with a traumatic or non-traumatic abdominal surgical emergency were included. The studied variables included clinical and paraclinical data. The variable of interest was death within 30 days of the surgery. Logistic regression was used to identify the factors independently associated with mortality. Risk factors identified after logistic regression analysis were weighted using odds ratio (OR) values rounded to the nearest whole number. The predictive capacity of the score was evaluated by analyzing the ROC (Receiver Operating Characteristic) curve based on the area under the curve (AUC).ResultsA total of 1114 patient records were included, with a mortality rate of 4.4%. Diagnoses were observed in patients included appendicitis in 39.8% of cases (n = 444), followed by peritonitis in 22.3% (n = 249), intestinal obstruction in 18.5% (n = 205), strangulated hernias in 10.5% (n = 117), and abdominal trauma in 6.1%. Logistic regression, established the following scores: age > 40 years (score 2), ASA status grade 2 or higher (score 1), presence of a positive QSIRS score (score 2), diagnosis of peritonitis (score 2), diagnosis of intestinal obstruction (score 1), and the presence of intestinal necrosis (score 3). The score is positive if the total is strictly greater than 5, indicating a 17.7% risk of mortality. This score had a high predictive capacity with an AUC of 0.7397.ConclusionThis study enabled the establishment of a score that allows for the early identification of at-risk patients, even in constrained resource settings, facilitating appropriate perioperative management and timely surgical intervention to reduce the risk of complications. This approach, focused on early recognition of high-risk patients, is crucial for improving clinical outcomes in abdominal surgical emergencies.

Unveiling patterns in pediatric appendectomy: A comparative study on healthcare resource capacity and surgical decisions in Brazil.

Appendicitis is the most prevalent surgical emergency in children. This study examined hospital infrastructure, surgical techniques, patient demographics, and hospitalization parameters to assess the provision of safe and adequate care within the Brazilian public healthcare system. Pediatric hospitalizations for acute appendicitis in 2022 were extracted from the Brazilian national database. We included all hospitalizations for patients aged 0-16years with a primary ICD-10 diagnosis of acute appendicitis who underwent an operation. Parameters of interest were the type of surgical approach, mortality, and total cost of hospitalization. Facilities were defined as basic-facility, full-facility, and pediatric according to the level of pediatric resources available. In 2022, there were 29,983 pediatric appendectomies due to acute appendicitis. Of these, 90.2% were open appendectomies. Most occurred in basic-facility general hospitals (53.0%), followed by full-facility (35.2%) and pediatric hospitals (11.8%). Full-facility hospitals had a higher median cost (USD126.3, IQR 99.5-154.4) compared to basic (USD96.8, IQR 87.6-130.1) and pediatric hospitals (USD103.0, IQR 91.9-117.5), though the cost difference between basic and pediatric was not significant (p=0.367). Death was a rare event across all levels of hospital infrastructure and for all types of procedures performed. The majority of hospitalizations for acute appendicitis occurred in hospitals with minimal pediatric infrastructure. Open appendectomies remain the most predominant procedure across all hospital types.

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.

A Case-control Study on the Correlation between Serum Bilirubin Levels and Various Types of Appendicitis

Background Acute appendicitis is one of the most common types of surgical emergencies. Among laboratory factors, hyperbilirubinemia has recently been identified as a strong predictor of preoperative perforation and gangrene. Aim This study aimed to investigate the correlation between serum bilirubin levels and types of appendicitis. Methods This case-control study was conducted in 2022 using the convenience sampling method on 100 patients who were referred to the emergency department of Imam Khomeini Hospital in Jiroft with abdominal pain. These patients were diagnosed with appendicitis based on the initial clinical examinations. The white blood cells and total bilirubin levels were measured for all the patients. Intraoperative macroscopic findings were recorded by the surgeon, and the pathological results of the specimen were reported. Data was analyzed using SPSS 24, including descriptive and inferential statistics at the significance level of P&lt;0.05. Results Among 100 patients aged between 28.5±14.8, 48% were men, and the rest were women. There was a significant difference between the mean of bilirubin levels in patients with complicated and uncomplicated appendicitis (P &lt;0.01). The results of logistic regression analysis showed that the period of onset of symptoms to hospitalization, leukocytosis level, and preoperative total bilirubin level were significant variables for diagnosing complicated appendicitis (P&lt;0.05). Conclusion In this study, we found that patients with complicated appendicitis had higher total bilirubin levels than patients with uncomplicated appendicitis. Therefore, patients with hyperbilirubinemia and clinical symptoms of appendicitis should be considered as more probable cases of perforation than those with normal bilirubin levels.
