The presented case involves a 65-year-old African American male who reports a two-day history of intermittent epigastric pain radiating to the back, which has worsened over time, accompanied by vomiting after lunch. The initial subjective documentation provides relevant patient history; however, additional information could enhance understanding and aid diagnosis. For instance, further details about the character, intensity, duration of the pain, and any alleviating or aggravating factors would be valuable. Clarification regarding the nature of the vomitus—such as presence of blood or bile—would also be informative. Additionally, assessing for associated symptoms like nausea, diarrhea, jaundice, or dizziness could help narrow the differential diagnosis. Details about recent food intake, alcohol consumption, or recent trauma might also be pertinent, given the suspicion of abdominal pathology.
Reviewing the objective findings, vital signs reveal hypotension (BP 91/60), elevated heart rate (P 76), and normal temperature (98.2°F), which could suggest hemodynamic compromise or ongoing bleeding. Physical exam notes epigastric tenderness with guarding but no rebound or palpable mass, indicative of an acute intra-abdominal process. Nonetheless, additional objective data could strengthen the assessment. For example, documenting bowel sounds, assessing for rigidity or peritoneal signs, and inspecting for signs of jaundice or abnormal pulsations would be advantageous. Laboratory data, such as complete blood count, serum amylase and lipase, liver function tests, and a basic metabolic panel, should be included to better characterize the patient's condition. Auscultation findings, respiratory assessment, and further abdominal exam details would also provide a more comprehensive objective picture.
The current assessment lists differential diagnoses including abdominal aortic aneurysm (AAA), perforated ulcer, and pancreatitis. While these are reasonable considerations based on the presentation—epigastric
pain radiating to the back, hypotension, and guarding—the documentation does not specify supporting evidence such as imaging or lab results. The suspicion of AAA might be supported if pulsatile abdominal masses are palpable or via ultrasound; however, the absence of mention limits certainty. Perforated ulcer and pancreatitis fit the symptomatology, but confirmation through diagnostics such as imaging or lab testing is vital. Hence, while the assessment directionally aligns with the subjective and objective findings, it remains preliminary.
Appropriate diagnostic tests for this patient include abdominal ultrasound and contrast-enhanced computed tomography (CTA). An abdominal ultrasound is useful for detecting AAA and evaluating vascular anatomy rapidly at bedside. CTA provides detailed visualization of the aorta, and can better identify a rupture or aneurysm and other intra-abdominal pathology such as perforation or pancreatic inflammation. Laboratory testing should include serum amylase, lipase, white blood cell count, liver function tests, and blood cultures if infection or perforation is suspected. In the context of suspected perforated ulcer, an upright abdominal and chest X-ray could reveal free air under the diaphragm, indicative of perforation. These diagnostic outcomes would help differentiate between the listed differential diagnoses and guide urgent management.
Accepting or rejecting the current preliminary diagnosis hinges on diagnostic findings. If imaging confirms an abdominal aortic aneurysm, especially if ruptured, surgical intervention becomes urgent. Conversely, elevated lipase with imaging consistent with pancreatic inflammation would corroborate pancreatitis. Given the presentation, a perforated ulcer remains a significant concern, especially with vomiting and epigastric tenderness. The initial assessment remains broad; thus, definitive diagnostics are crucial before confirming any diagnosis.
Three differential diagnoses to consider include: 1) Abdominal Aortic Aneurysm (AAA) rupture, given the hypotension, abdominal tenderness, and potential pulsatile mass—supported by studies such as Olsson et al. (2010), which emphasize rapid diagnosis of AAA rupture is life-saving (Olsson et al., 2010). 2) Acute pancreatitis, evidenced by epigastric pain radiating to the back, elevated lipase, and guarding—as described by Banks et al. (2013), early recognition and management improve outcomes (Banks et al., 2013). 3) Peptic ulcer disease with perforation, supported by the history of epigastric pain and vomiting—perforation is a surgical emergency and can be diagnosed via free air on imaging, per O’Connell et al. (2020). Each diagnosis requires targeted workup, including imaging and laboratory testing, grounding clinical suspicion in evidence-based practice.
