What is the appropriate evaluation and management for a 39-year-old male presenting with right lower quadrant abdominal pain, nausea, vomiting, and constipation, with suspicion of appendicitis or other surgical conditions?

Surgical Consultation for Right Lower Quadrant Abdominal Pain

CONSULTATION NOTE

DATE: [Current Date] PATIENT: 39-year-old male REASON FOR CONSULTATION: Right lower quadrant abdominal pain, suspected appendicitis

HISTORY OF PRESENT ILLNESS

The patient most likely has acute appendicitis and requires urgent surgical intervention. 1, 2

39-year-old male with no past medical history presenting with right lower quadrant abdominal pain that began two days ago. Pain is associated with nausea and vomiting (three episodes). Patient reports constipation for several days and pressure in abdomen when attempting to urinate. Patient denies fever or diarrhea. Last oral intake was limited to a few sips of water a few hours ago, with last food intake on Wednesday.

PAST MEDICAL HISTORY

• No significant past medical history • Patient mentions prior constipation requiring colonoscopy • Quit smoking cigarettes 15 years ago • No alcohol use • No current medications • No known drug allergies

PHYSICAL EXAMINATION

• Vital Signs: [To be completed during examination] • General: [To be completed during examination] • Abdomen: [To be completed during examination - focus on right lower quadrant tenderness, rebound tenderness, guarding]

ASSESSMENT AND PLAN

Based on the clinical presentation of right lower quadrant pain, nausea, vomiting, and constipation, acute appendicitis is the most likely diagnosis. According to the American College of Emergency Physicians and American College of Radiology guidelines, the following diagnostic and management approach is recommended 1:

1. Laboratory Studies:

   • Complete blood count with differential to evaluate for leukocytosis
   • Basic metabolic panel
   • Urinalysis to rule out urinary tract pathology
   • Pregnancy test if applicable

2. Imaging:

   • CT abdomen and pelvis with IV contrast is the recommended first-line imaging modality for suspected appendicitis in adult patients 1
   • CT findings suggestive of appendicitis include appendiceal dilatation (≥7 mm), wall thickening, periappendiceal fat stranding, and presence of appendicoliths 2, 3

3. Preoperative Management:

   • NPO status
   • IV fluid resuscitation
   • Broad-spectrum antibiotics effective against gram-negative and anaerobic organisms (e.g., piperacillin-tazobactam or ceftriaxone plus metronidazole) 2, 3
   • Adequate pain control with appropriate analgesics

4. Surgical Intervention:

   • Laparoscopic appendectomy is the standard surgical approach for acute appendicitis 3
   • Open appendectomy may be considered based on patient factors and surgeon preference

CLINICAL PEARLS AND PITFALLS

• Diagnostic Challenges: Relying solely on clinical signs and symptoms can lead to delayed diagnosis, especially in patients with atypical presentations 2
• Perforation Risk: Delayed diagnosis increases the risk of perforation, which occurs in 17-32% of patients with acute appendicitis and can lead to sepsis 2, 4
• Imaging Considerations: While clinical evaluation remains important, imaging significantly reduces the negative appendectomy rate from as high as 25% to approximately 1-3% 1, 5
• Antibiotics-Only Approach: While increasing evidence suggests that antibiotics alone may successfully treat uncomplicated appendicitis in selected patients, surgical management remains the standard of care, especially in patients with high-risk CT findings such as appendicolith, mass effect, or significantly dilated appendix (>13 mm) 3

I will proceed with the above evaluation and management plan. Will update the team after imaging results are available to determine the need for urgent surgical intervention.
