Diverticular disease and LGIB Flashcards
4 types of Diverticular disease
I) asymptomatic diverticulosis (most common)
2) painful diverticulosis (contraction of hypertrophied colonic muscle)
3) diverticular bleeding
4) diverticulitis
Painfull diverticulosis
luminal narrowing, pencil-thin stools, and pain before defecation
Treat with bulking agents such as psyllium
Diverticular bleeding usually originates in the
sigmoid
the most common cause of colonic bleeding in the elderly
Diverticular bleeding
angiodysplasia is next on the list and often results in more severe bleeds.
Treatment of Diverticular bleeding
Stabilize patient if needed, rule out UGI bleed with NG aspirate or endoscopy
BUN/Cr>30:1 suggests what?
UGI bleed
Diagnose diverticular bleeding with
colonoscopy or technetium-tagged RBC scan. Angiography works if bleeding is severe or continuous.
Diverticulitis signs and symptoms
1) LLQ pain
2) fever
3) high WBC
4) LLQ tenderness-may be localized, rebound tenderness
Diagnosis of diverticulitis
CT is most useful in assessing diverticulitis: It may show areas of thickened sigmoid colon or pericolic fluid accumulation.
Avoid GI colonoscopy on any patient with diverticulitis.
Treat mild diverticulitis in a patient able to drink and without peritoneal signs
outpatient metronidazole (Gram-neg anaerobic) plus either ciprofloxacin or TMP/SMX (Gram neg aerobic) and close follow-up.
Mod to severe diverticulitis
Inpatient parenteral treatment 1)dual-drug therapy such as (best!): aminoglycoside or ciprofloxacin + clindamycin or metronidazole 2)single-drug therapy such as: • ticarcillin/clavulanic acid • imipenem/cilastatin • cefotetan
follow up after treatment of diverticulitis
Perforation from sigmoid colon cancer can present similarly to diverticulitis, so follow up in patients > 50 with a flexsig/colonoscopy after the acute condition resolves.
the most frequent congenital GI anomaly
Meckel diverticulum
when does meckel diverticulum ulcerate and bleed?
Although < 1/2 of these diverticula have gastric mucosa, only these ulcerate and bleed
