From the Guidelines
The patient's symptoms of severe abdominal pain post-ingestion, with positive ketones, normal liver enzymes, and normal kidney function, in the context of a soft abdomen and no bowel sounds, are most likely indicative of a gastrointestinal issue, such as a bowel obstruction or ileus, which requires immediate medical attention. The presence of positive ketones suggests that the patient may be experiencing reduced caloric intake due to pain with eating, which can lead to a range of complications 1. Given the patient's symptoms and normal test results, it is essential to consider a comprehensive diagnostic approach, including imaging studies, to rule out other conditions such as gastrointestinal perforation, inflammation, or infarction.
The study by Pandharipande et al [@3@] highlights the importance of imaging in determining management, especially in instances where the positive result is not concordant with the initial diagnostic consideration. In this case, a CT scan of the abdomen and pelvis may be necessary to evaluate the patient's symptoms and guide further management. The ACR Appropriateness Criteria 1 also emphasize the role of imaging in evaluating patients with nonspecific abdominal pain, with or without fever, and in immunocompromised patients with acute abdominal pain.
Key considerations in the patient's management include:
- Immediate medical attention to rule out life-threatening conditions such as bowel obstruction or perforation
- Comprehensive diagnostic approach, including imaging studies, to guide further management
- Monitoring of the patient's condition, including vital signs, abdominal examination, and laboratory results, to promptly identify any changes or complications
- Consideration of a gastroenterology consultation for further evaluation and management of the patient's symptoms.
From the Research
Possible Causes of Severe Abdominal Pain
- Acute gastric dilatation is a potential cause of severe abdominal pain post-ingestion, as seen in patients with anorexia nervosa after binge eating 2, 3.
- Idiopathic omental bleeding is a rare cause of acute abdomen, presenting with abdominal pain and potentially life-threatening complications 4.
- Gastrointestinal diseases such as gastroesophageal reflux disease (GERD), epigastric pain syndrome, duodenal ulcers, gastric ulcers, irritable bowel syndrome, and Crohn's disease can cause abdominal pain, but the specific presentation and symptoms may vary 5.
- Total parenteral nutrition-related gastroenterological complications can also cause abdominal pain, although this is more relevant to patients with chronic gastrointestinal failure 6.
Key Considerations
- The presence of positive ketones, normal liver enzymes, and normal kidney function, along with a soft abdomen and no bowel sounds, may indicate a gastrointestinal issue rather than a hepatic or renal problem.
- The patient's symptoms and medical history should be carefully evaluated to determine the underlying cause of the abdominal pain.
- Imaging studies such as computed tomography scans and endoscopy may be necessary to diagnose and manage the condition effectively 2, 3, 4.
