Infectious Disease Compendium

Diverticulosis/itis

Diagnosis

Abdominal pain, CT best diagnostic tool.

Epidemiologic Risks

Mid to old age.

Microbiology

Bowel flora Escherichia coli, anaerobes and streptococci.

Empiric Therapy

A third generation cephalosporins PLUS metronidazole is my fav, po therapy or beta lactam allergy would be a quinolone PLUS metronidazole OR tmp/sulfa PLUS metronidazole. Amoxicillin/clavulanate alone should be fine as well.

Specific Therapy

10 - 14 days total.

Pearls

If the tic perforates, laproscopic resection has worser (yes, worser) outcomes (PubMed).

And there was one study in England where uncomplicated diverticulitis was treated with observation and they did as well as those with antibiotics(Pubmed. I don't know. I doubt I would have the courage to do this without another study to back it up.
