PURPOSE: Ultrasonography (US) has good accuracy for diagnosing appendicitis when it is performed by emergency physicians. This study aimed to determine the amount of experience that is required to achieve competency in this field. METHODS: Three novice emergency medicine residents completed a 1-day training course regarding the US diagnosis of appendicitis. Then, they performed appendix US in the emergency department on patients complaining of right lower quadrant pain...

PURPOSE: To evaluate different sonographic signs of strangulating closed-loop obstruction retrospectively. MATERIALS AND METHODS: Over a period of approximately 10 years all documents, US scans and video clips of patients with strangulating intestinal obstruction were reviewed. The following sonographic signs were evaluated: akinetic bowel loops; echo-free luminal content; hyperechoic congestion of the mesentery; free peritoneal fluid; bowel wall thickening; signs of ischemia on color Doppler or contrast-enhanced US...

BACKGROUND: Computed tomography (CT) has largely become standard of care for diagnosing appendicitis at the expense of increased patient radiation exposure, cost, and time to surgical intervention. To date, there are very limited data on the accuracy of bedside ultrasound (BUS) for the diagnosis of appendicitis in adults. OBJECTIVE: The objective of this study is to evaluate test characteristics of BUS for diagnosis of acute appendicitis in the emergency department...

Hypertrophic pyloric stenosis (HPS) is an acute abdominal emergency in infants that often presents to Emergency Departments. The clinical diagnosis of HPS relies on palpation of an olive-sized mass in the right upper quadrant of an infant with a history of projectile vomiting. However, studies have shown that clinicians cannot detect the olive in 11% to 51% of cases. Ultrasonography is the imaging modality of choice to diagnose HPS. HPS has a highly characteristic sonographic appearance that makes it readily identifiable on ultrasound...

STUDY OBJECTIVE: We investigate the performance characteristics of bedside emergency department (ED) ultrasonography by nonradiologist physician sonographers in the diagnosis of ileocolic intussusception in children. METHODS: This was a prospective, observational study conducted in a pediatric ED of an urban tertiary care children's hospital. Pediatric emergency physicians with no experience in bowel ultrasonography underwent a focused 1-hour training session conducted by a pediatric radiologist...

OBJECTIVES: To evaluate the accuracy of emergency physicians using bedside ultrasound to detect appendicitis (BUSA). METHODS: Patients presenting to the emergency department with a clinical suspicion of appendicitis were prospectively enrolled and received a 5-min BUSA. Patients received routine work-up for acute appendicitis as deemed appropriate by the attending physician. Radiologists and consulting surgeons were blinded to BUSA results. The criterion standard for the presence or absence of acute appendicitis was the pathology report for patients who received appendectomies, and telephone follow-up for patients discharged home without surgical intervention...

STUDY OBJECTIVE: To determine the accuracy of diagnosing appendicitis in the pediatric population by using graded compression ultrasonography. DESIGN: Retrospective case review. SETTING: University-affiliated community hospital with an emergency department census of approximately 19,000 pediatric visits per year. TYPE OF PARTICIPANTS: Ninety-eight children (age less than 13 years) with clinically suspected appendicitis who had graded compression sonographic studies during the 24-month study period...

PURPOSE: This study was conducted to investigate the diagnostic value of a new sonographic technique for the detection of intraabdominal free air. METHODS: Seventy-two patients with a suspected gastrointestinal tract perforation were included in the study and prospectively evaluated by sonography and abdominal and chest radiography for the detection of intraperitoneal free air. A new sonographic technique (the scissors maneuver) was used to detect intraperitoneal free air superficial to the liver; the maneuver consists of applying and then releasing slight pressure onto the abdominal wall with the caudal part of a parasagittaly oriented linear-array probe...

BACKGROUND: Plain film radiography (x-ray) is often the initial study in patients with suspected small bowel obstruction (SBO) to expedite patient care. OBJECTIVE: To compare bedside ultrasonography (US) and x-ray for the detection of SBO. METHODS: This was a prospective study using a convenience sample of patients presenting to the emergency department (ED) with abdominal pain, vomiting, or other symptoms suggestive of a SBO. Patients were evaluated with US prior to x-ray and CT...

BACKGROUND: Esophageal foreign body (EFB) and impaction are common gastrointestinal emergencies. Detection with standard imaging can be challenging. Computed tomography is a commonly used non-invasive imaging modality, but is not 100% sensitive and not always feasible. Sensitivity of plain film x-ray varies widely and the addition of a barium swallow can obscure evaluation by subsequent esophagogastroduodenoscopy (EGD). Use of emergency ultrasound (EUS) for detection of EFB in adults has not been previously studied...

BACKGROUND: The use of ultrasonography (US) to diagnose appendicitis is well established. More recently, point-of-care ultrasonography (POCUS) has also been studied for the diagnosis of appendicitis, which may also prove a valuable diagnostic tool. The purpose of this study was through systematic review and meta-analysis to identify the test characteristics of POCUS, specifically US performed by a nonradiologist physician, in accurately diagnosing acute appendicitis in patients of any age...

BACKGROUND: Small bowel obstruction (SBO) is a clinical condition that is often initially diagnosed and managed in the emergency department (ED). The high rates of potential complications that are associated with an SBO make it essential for the emergency physician (EP) to make a timely and accurate diagnosis. OBJECTIVES: The primary objective was to perform a systematic review and meta-analysis of the history, physical examination, and imaging modalities associated with the diagnosis of SBO...
