Abstract
BACKGROUND The optimal diagnosis and treatment of appendicitis remains controversial. This systematic review details the evidence and current best practices for the evaluation and management of uncomplicated and complicated appendicitis in adults and children. METHODS Eight questions regarding the diagnosis and management of appendicitis were formulated. PubMed, Embase, CINAHL, Cochrane and clinicaltrials.gov/NLM were queried for articles published from 2010 to 2022 with key words related to at least one question. Randomized and non-randomized studies were included. Two reviewers screened each publication for eligibility and then extracted data from eligible studies. Random effects meta-analyses were performed on all quantitative data. The quality of randomized and non-randomized studies was assessed using the Cochrane Risk of Bias 2.0 or Newcastle Ottawa Scale, respectively. RESULTS 2792 studies were screened and 261 were included. Most had a high risk of bias. Computerized tomography scan yielded the highest sensitivity (> 80%) and specificity (> 93%) in the adult population, although high variability existed. In adults with uncomplicated appendicitis, non-operative management resulted in higher odds of readmission (OR 6.10) and need for operation (OR 20.09), but less time to return to work/school (SMD - 1.78). In pediatric patients with uncomplicated appendicitis, non-operative management also resulted in higher odds of need for operation (OR 38.31). In adult patients with complicated appendicitis, there were higher odds of need for operation following antibiotic treatment only (OR 29.00), while pediatric patients had higher odds of abscess formation (OR 2.23). In pediatric patients undergoing appendectomy for complicated appendicitis, higher risk of reoperation at any time point was observed in patients who had drains placed at the time of operation (RR 2.04). CONCLUSIONS This review demonstrates the diagnosis and treatment of appendicitis remains nuanced. A personalized approach and appropriate patient selection remain key to treatment success. Further research on controversies in treatment would be useful for optimal management.

Abstract
Abstract
Background
Acute appendicitis is an infrequent pathology in children under 4 years of age, and its diagnosis is a clinical challenge that can lead to late detection. The intention of this study is to describe the clinical and surgical findings and to explore factors and outcomes associated with appendiceal perforation in patients under 4 years of age with histologically confirmed acute appendicitis. Cross-sectional study of historical data is on patients with a pathologic diagnosis of appendicitis. Clinical, surgical, and pathological variables were described. The relationship between the presence of perforation and associated factors and outcomes was explored using odds ratios (OR) and 95% confidence intervals.
Results
Seventy-five patients were found between 2013 and 2019. Seventy-four cases presented with pain on palpation, 56 (75%) with signs of peritoneal irritation, and 70 (93%) with sepsis on admission to the emergency room. An ultrasound was done on 57 patients (76%), and only 26 (45%) were suggestive of appendicitis. Forty-one (55%) cases were operated on by open surgery and 34 (45%) by laparoscopy. In 61 (81%), they were perforated, and 48 (64%) presented peritonitis. Perforation was associated with increased hospital days (OR = 2.54 [1.60−4.03]), days of antibiotics (OR = 4.40 [2.09−9.25]), and admission to intensive care (OR = 9.65 [1.18−78.57]).
Conclusions
Abdominal pain reported by parents, pain on abdominal palpation, and clinical criteria of sepsis on admission to the emergency room are common features. Acute appendicitis complicated by perforation leads to high morbidity due to longer antibiotic treatment, hospitalization days, admission to PICU, and postoperative ileus.

Abstract
RATIONALE AND OBJECTIVES At our institution, on-call radiology residents perform emergent ultrasounds (US) outside of departmental working hours. The aim of the study was to evaluate radiology resident-performed US for clinically suspected acute appendicitis in women under the age of 40. MATERIALS AND METHODS Retrospective review of 104 consecutive US scans outside of departmental working hours by radiology residents, and 104 consecutive US studies scanned during departmental working hours by sonographers, in women under the age of 40 for clinically suspected appendicitis . RESULTS Appendix visualization rate was 27% for the resident group (sonographer group: 30%, p = 0.759). The sensitivity and specificity of US for appendicitis were 63% (95% confidence interval: 41%-81%) and 98% (95% CI: 91%-100%), respectively for the resident group (sonographer group: 69% [95% CI: 41%-89 %] and 98% [95% CI: 92%-100%], respectively). An alternative cause for right lower quadrant pain was offered in 17% of resident group cases (sonographer group: 21%, p = 0.598). Follow-up CT or MRI was performed in 47% of resident cases (sonographer group: 44%, p = 0.781). Residents performed more focused US (i.e. not imaging the pelvic organs), at 34% (sonographer group: 1%, p < 0.001). When only focused scanning was performed by residents, there was a trend toward increased downstream imaging (CT or MRI), odds ratio = 2.76 (95% CI: 0.99-7.70). CONCLUSIONS Out-of-hours US scans performed by radiology residents had similar performance characteristics compared to departmental sonographers. We discovered an increased rate of downstream imaging in cases in which residents performed limited scans and did not document visualization of the pelvic organs.

Abstract
BACKGROUND Ultrasound has the first line investigation role in the diagnosis of acute appendicitis in children. The purpose of this study was to perform a quality assessment review on the visualization rate of appendix on ultrasound in children in the community hospital setting. METHODS A retrospective chart review of the abdominal ultrasound findings for the visualization of the appendix was performed on paediatric patients ranging from 5 to 18 years. Data were collected from the two community hospitals of Toronto by using hospital electronic medical record for the ultrasound findings in patients presented with abdominal pain. RESULTS Data from two community hospitals indicated visualization rate of the appendix as 11.0% and 23.2% for site 1 and site 2 respectively. In cases where the ultrasound was repeated the visualization rate remains the same. A two-proportion z-test was performed to find whether the visualization of appendix increases the likelihood of diagnosing appendicitis. The results revealed that the visualization of an appendix (P=0.52), significantly improved the diagnosis of appendicitis (z=34, P<0.001). CONCLUSION Visualization of an appendix on ultrasound increases the likelihood of correctly diagnosing appendicitis. In our study, we found low visualization rate of appendix on ultrasound that could be the result of many factors that contribute towards the low visualization rate of an appendix on ultrasound. Hence, the challenges in identifying appendix should be minimized to improve the visualization and diagnosis of appendicitis on ultrasound.

Abstract
Radiology reports are the principal form of communication with the referring provider. Unfortunately, they can be a form of communication riddled with errors and inscrutable statements burying the intended meaning, failing to achieve the main task for which it was made: communicating key imaging findings as they pertain to the clinical question being posed. Structured reporting is a multifaceted and modular solution to problematic reports, with variable iterations and benefits. Structured reports have been adapted across departments and even national societies, with standardized format, content and language. Newer developments include contextual reporting and common data elements. Herein, we discuss the various forms and levels of structured reporting and the latest advancements, as well as the general acceptance within radiology. We also discuss some areas for improvement as the practice of structured reporting matures.

Abstract
Background To determined the accuracy of ultrasound in diagnosis of acute appendicitis in children keeping histopathology as gold standard. Methods A prospective evaluations of all ultrasound for appendicitis from January 1, 2014, to June 15, 2017, was conducted at our hospital. A diagnostic protocol was implemented to reduce radiation exposure employing US as the initial imaging modality followed by CT for non-diagnostic US studies in patients with an equivocal clinical presentation. The imaging, operative findings, and pathology of 223 patients (females 80, males 143, age less than 14years) with diagnosed appendicitis were collected. The sensitivity, specificity, predictive value, and negative appendectomy rate were also analyzed. All those patients which had subjected to surgery were included to evaluate the true result of ultrasound in diagnosis of appendicitis. Results Of the 223 pediatric appendectomies performed in this time period, a total of 192 (86%) were diagnosed by ultrasound. The histopathology of 8 was normal (3.6%), CT done in 11 and three was normal. The negative appendectomy rate was 3.6%. US were the sole imaging modality in all patients. Conclusions In the diagnosis of acute appendicitis in children, ultrasound is useful and accurate mode, which results in a significant decrease in negative appendectomies with no increase in the number of CT scans. This has important implications in the reduction of childhood radiation exposure. Study design cross sectional validation. Total 223 Diagnose as acute appendicitis on initial clinical basis and follow by ultrasound study. All went for surgery, 8 patient negative by histopathology. Diagnosis by ultrasound 192 out of 223, Sensitivity 86%. Accuracy reaches 92% with secondary signs on ultrasound finding.

Abstract
OBJECTIVE To evaluate the accuracy of ultrasonography for the diagnosis of acute appendicitis in adults, to calculate the negative appendicectomy rate in operated patients and the accuracy of pre-defined diagnostic categories and to identify statistically significant signs and symptoms of acute appendicitis in ultrasonography. MATERIAL AND METHODS Descriptive prospective study in which we collected the findings of the urgent ultrasonographies ordered in a one-year period for adult patients with pain in the right iliac fossa (RIF), along with their symptoms. We classified them in 5 different diagnostic categories presented in the radiological report: normal appendix, non-visible appendix and no secondary signs, non-conclusive, probable appendicitis, certain appendicitis. By mean of the Stata14 software descriptive analysis, T-test and Chi-square were performed and the data were compared with the final pathological report. RESULTS Population: 139 patients (45% men, 55% women), mean age: 32,68 (15-84). Prevalence of acute appendicitis: 50,35% (70/139). Negative appendicectomy rate: 0%. Negative predictive value for the categories 1,2 and 3 taken together: 90,78%. Positive predictive value for the categories 4 and 5 taken together: 100%. Ultrasound sensibility and specificity 90% and 100%, respectively. Statistically significant signs and symptoms (p<0.05): RIF pain, fever, leukocytosis, left shift, visible appendix, non-compressibility, hyperechogenic fat, appendicolith and free fluid. CONCLUSION Ultrasound is very accurate for the diagnosis of acute appendicitis in adults.

Abstract
OBJECTIVE Diagnosing pediatric appendicitis is difficult because clinical findings are nonspecific. Improved accuracy can be obtained with ultrasound (US), CT, or MRI, despite considerable variation in their use at different institutions. This article reviews the evidence for best practices in imaging pediatric appendicitis. CONCLUSION When each modality is optimally used, a stepwise imaging approach that begins with graded compression US and proceeds to CT or MRI in select cases is currently best practice.
