What is the appropriate management for a patient who presents repeatedly to the emergency department with abdominal pain despite normal ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and laboratory studies?

Management of Recurrent Emergency Department Visits for Abdominal Pain with Negative Workup

After comprehensive imaging (US, CT, MRI) and laboratory studies have ruled out acute pathology, further repetitive imaging is not indicated and management should shift from diagnostic pursuit to addressing functional pain disorders, central sensitization, and establishing outpatient continuity of care.

Stop the Imaging Cycle

The evidence is clear that repeat imaging in patients with recurrent, low-risk abdominal pain after negative initial workup has minimal diagnostic yield and exposes patients to unnecessary radiation 1. Approximately one-third of ED patients with abdominal pain never receive a definitive diagnosis despite extensive workup 2. When imaging has already included US, CT, and MRI with normal results, the probability of finding new acute pathology on repeat imaging is extremely low.

Key Points on Imaging Futility:

• Studies show repeat CT frequency ranges from 2-47% but diagnostic yield that changes management varies widely (5-67%), with most changes occurring when the index CT was not truly negative 1
• One case report documented a patient with 46 imaging studies over one year for recurrent abdominal pain, all negative 3
• Avoid repeated and useless X-ray exposure whenever possible 4

Recognize Central Sensitization and Functional Pain

This clinical presentation strongly suggests a disorder of gut-brain interaction (formerly called functional GI disorders) or central sensitization syndrome 5, 3. These are real, physiologic conditions—not "all in the patient's head."

Clinical Features to Recognize:

• High pain severity (average pain scores 7/10) despite negative workup 5
• Symptom resolution between episodes
• Multiple prior ED visits for similar complaints
• High rates of anxiety (PROMIS T-score 56.0) and pain interference (T-score 60.8) 5
• Central Sensitization Inventory scores often demonstrate severe underlying sensitization 3

Immediate ED Management Strategy

1. Avoid Opioids

Despite high pain severity, opioid administration (occurring in ~50% of these patients) perpetuates the cycle and does not address the underlying pathophysiology 5. Opioids can worsen functional GI disorders and contribute to opioid-induced hyperalgesia.

2. Provide Appropriate Analgesia

• Consider non-opioid analgesics (NSAIDs if not contraindicated, acetaminophen)
• Antispasmodics for cramping pain
• Consider low-dose anxiolytics for acute anxiety component

3. Patient Education

Counsel the patient about central sensitization and functional pain disorders 3. Explain that:

• Their pain is real and physiologic
• The nervous system has become hypersensitive
• Repeated imaging will not help and carries risks
• Effective treatments exist but require outpatient management

Establish Outpatient Care Plan

The critical intervention is establishing appropriate follow-up, not ordering more tests 5, 3.

Referrals to Arrange:

• Primary care physician for coordination
• Gastroenterology for evaluation of disorders of gut-brain interaction (IBS, functional dyspepsia, centrally mediated abdominal pain syndrome)
• Pain management or chronic pain clinic for central sensitization
• Behavioral health for cognitive-behavioral therapy, which has strong evidence for functional GI disorders

Biopsychosocial Assessment:

The evidence shows these patients have significant social determinants of health issues and psychosocial factors that require addressing 5:

• Screen for anxiety and depression
• Assess pain interference with daily activities
• Identify barriers to outpatient care access

Red Flags That Would Warrant Re-evaluation

Only pursue additional imaging if NEW concerning features develop:

• Fever with hemodynamic instability
• Peritoneal signs on examination
• Significant change in pain character or location
• New laboratory abnormalities (leukocytosis, elevated inflammatory markers)
• Unintentional weight loss
• GI bleeding
• Age >50 with new-onset symptoms (consider malignancy)

See the patient twice if severe acute pain with normal initial workup 4—but this means clinical re-examination, not automatic repeat imaging.

Common Pitfalls to Avoid

1. Ordering "just one more CT" to reassure the patient or yourself—this reinforces illness behavior and the belief that imaging will solve the problem 1

2. Dismissing the patient's pain as "not real"—functional pain disorders have demonstrable pathophysiology and require specific treatment 5, 3

3. Prescribing short courses of opioids without explanation—this is associated with patient dissatisfaction and perpetuates ED utilization 3

4. Failing to establish outpatient follow-up—without a care plan, the 30-day return rate is approximately 11% 5

Special Considerations

• Elderly patients may show atypical presentations—maintain higher suspicion for serious pathology in this population 4
• Consider abdominal wall pain (musculoskeletal)—often overlooked and can mimic visceral pain 4
• Pregnancy status—always check beta-hCG in women of reproductive age before any imaging decisions 6

The goal is to break the cycle of repetitive ED visits and imaging by addressing the underlying pain disorder through appropriate outpatient management, not by continuing the diagnostic pursuit that has already been exhaustive and unrevealing.
