Final answer:
Diverticulitis is the likely diagnosis for a 69-year-old male with fever, leukocytosis, and LLQ pain. A CT scan can confirm the diagnosis. The recommended GI antibiotic strategies for diverticulitis include MAG or Ciprofloxacin + Metro. Recurrent UTIs with air and fecal material in the U/A may suggest a complication like colovesical fistula.
Step-by-step explanation:
The diagnosis for a 69-year-old male with fever, leukocytosis, and LLQ pain is diverticulitis. Diverticulitis is a digestive disease in which tiny pouches in the wall of the large intestine become infected and inflamed. A CT scan is commonly used for diagnostic testing to confirm diverticulitis.
In terms of the GI antibiotic strategies for diverticulitis, the recommended options include MAG (Metro, Amox, Genta) or Ciprofloxacin + Metro.
If the patient presents with recurrent UTIs weeks later and the urinalysis (U/A) shows air and fecal material, it may indicate a complication of diverticulitis, such as a fistula formation between the colon and urinary system. This condition is known as colovesical fistula.
