Differential Diagnosis
Diverticulitis
- Most likely given the LLQ tenderness, bloody diarrhea, and abdominal pain.
Gastroenteritis
- Acute diarrhea and nausea suggest viral or bacterial etiology, though bloody stool favors bacterial causes.
Infectious Colitis
- Bacterial pathogens are a concern, especially with recent food exposure at the senior center.
Ischemic Colitis
- Considered due to LLQ pain and bloody diarrhea, particularly in older adults with vascular comorbidities.
Inflammatory Bowel Disease (IBD)
- Less likely given the acute onset and patient’s age but remains a possibility.

Plan
- Labs
- CBC w diff, BMP, LFTs, Lipase, GI PCR Panel, Respiratory PCR Panel
- Imaging
- CTAP with IV Contrast
Results
CTAP with IV contrast:
- Findings of Colitis(wall thickening from the hepatic flexure of the colon to the sigmoid,and also most likely of the rectum).
- Postoperative findings
- No acute appendicitis
GI PCR: CAMPYLOBACTER SPP DNA DETECTED
#Campylobacter diarrhea associated with Colitis
- Start Maalox MAX 400-400-40 mg/5mL Suspension (5 mL every 6 hours)
- Start Famotidine 20 mg Tablet (twice a day for 30 days)
- Directed the patient to stay hydrated with oral fluids to prevent dehydration.
- Recommend following the BRAT diet (Bananas, Rice, Applesauce, Toast) to help with gastrointestinal recovery.
- Symptoms should improve in the next few days with treatment and hydration.
