Objective: We aimed to use the consensus opinion of a group of expert emergency physicians to derive a set of emergency diagnoses for acute abdominal pain that might be used as clinically significant outcomes for future research.

Methods: We conducted a cross-sectional survey of a convenience sample of emergency physicians with expertise in abdominal pain. These experts were authors of textbook chapters, peer-reviewed original research with a focus on abdominal pain or widely published clinical guidelines. Respondents were asked to categorize 50 possible diagnoses of acute abdominal pain into 1 of 3 categories: 1) unacceptable not to diagnose on the first emergency department (ED) visit; 2) although optimal to diagnose on first visit, failure to diagnose would not be expected to have serious adverse consequences provided the patient had follow-up within the next 2–7 days; 3) if not diagnosed during the first visit, unlikely to cause long-term risk to the patient provided the patient had follow-up within the next 1–2 months. Standard descriptive statistical analysis was used to summarize survey data.

Results: Thirty emergency physicians completed the survey. Of 50 total diagnoses, 16 were categorized as “unacceptable not to diagnose in the ED” with greater than 85% agreement, and 12 were categorized as “acceptable not to diagnose in the ED” with greater than 85% agreement.

Conclusion: Our study identifies a set of abdominal pain conditions considered by expert emergency physicians to be clinically important to diagnose during the initial ED visit. These diseases may be used as “clinically significant” outcomes for future research on abdominal pain.

Objective: Pneumonia is a well-known cause of acute abdominal pain in children. However, the utility of chest radiography in this setting is controversial. We sought to determine the prevalence of pneumonia in children under 12 years of age who had abdominal pain and underwent abdominal radiography when visiting an emergency department (ED). We also aimed to describe the signs and symptoms of children diagnosed with pneumonia in this context.

Methods: We conducted a retrospective analysis of electronic data from ED visits to a tertiary care centre by children 12 years of age and under who were seen between June 1, 2001, and June 30, 2003, and who underwent both an abdominal and a chest radiograph during the same visit, or an abdominal x-ray at a first visit as well as a chest x-ray in the 10 days following the initial visit.

Results: Of 1584 visits studied, 30 cases of pneumonia were identified, for a prevalence of 1.89% (95% confidence interval 1.22%-1.56%). If chest radiography had been limited to children who presented with fever, cough and symptoms of an upper respiratory tract infection (URTI), the diagnosis of pneumonia would have been missed in only 2/1584 visits (0.13%).

Conclusion: Children aged 12 years and under presenting to the ED with acute abdominal pain and in whom an abdominal radiograph is requested need only undergo a chest radiograph in the presence of cough, fever or other symptoms of a URTI.

A 28-year-old male with atraumatic abdominal pain and transient hypotension was assessed using bedside emergency department (ED) ultrasonography and contrast enhanced helical computed tomography (CT). Both tests revealed free intraperitoneal fluid, but neither detected a splenic defect. The patient subsequently underwent splenectomy for a ruptured spleen. His serology for typical viral causes was negative. This article discusses spontaneous splenic rupture, the role of imaging in diagnosis, and the limitations of ED ultrasound and contrast enhanced helical CT.
