Overview
Angiodysplasia must be differentiated from other diseases that cause hematochezia, melena, and iron deficiency anemia , such as hemorrhoids, diverticular disease and colon cancer.
Differentiating Angiodysplasia from other Diseases
Angiodysplasia must be differentiated from diverticulitis, hemorrhoids, colon cancer, massive upper GI bleed and inflammatory bowel disease.
| Diseases | Clinical manifestations | Para-clinical findings | Gold standard | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Symptoms | Physical examination | |||||||||||||
| Lab Findings | Imaging | Histopathology | ||||||||||||
| Symptom 1 | Symptom 2 | Symptom 3 | Physical exam 1 | Physical exam 2 | Physical exam 3 | Lab 1 | Lab 2 | Lab 3 | Imaging 1 | Imaging 2 | Imaging 3 | |||
| Diverticulitis | Abdominal cramps | Bloating | Diarrhoea | Left lower quadrant abdominal tenderness | Bowel sounds hypoactive/normoactive | Fever | Leukocytosis | Elevated ESR and CRP | Radiological test of choice - CT of abdomen and pelvis with contrast | Abdominal Ultrasound | MRI abdomen | Colonoscopy after resolution of inflammation | ||
| Hemorrhoids | Hematochezia | Anal pain | Anal protrusion | Skin tags | Fistulas or fissures | Prolapsed hemorrhoid | External hemorrhoids - distal to dentate line.
Internal hemorrhoids - proximal to dentate line. |
Anoscopy | ||||||
| Colon cancer | Tenesmus | Bowel habits change | Weight loss | Lmyphadenopathies | Abdominal mass | Hepatomegaly (metastasis) | Tumor marker - CEA | CT with contrast chest, abdomen and pelvis | Majority of colorectal cancers are carcinomas. | Colonoscopy | ||||
| Massive upper GI bleed | Hematemesis | Abdominal pain | Melena | Hemodynamic instability | Upper abdominal tenderness | Pale skin | Acute bleeding - normocytic anemia | Elevated BUN-to-Creatinine ratio >30:1 | CT angiography | Endoscopy | ||||
| Inflammatory bowel disease | Bloody diarrhea | Tenesmus | Abdominal pain | Tachycardia, fever, | Occult blood on digital rectal exam | Anal fistulas, abscesses | Microcytic anemia | Leukocytosis | Elevated ESR, CRP | Abdominal X ray - free air, bowel obstruction, toxic megacolon | Barium studies | Ultrasound/CT/MRI | UC- crypt abscess
Crohn's- transmural involvement, granulomas |
Endoscopy |
| Angiodysplasia | Asymptomatic | Occult lower GI bleed | No abdominal pain | Signs of anemia | Systolic ejection murmur (if aortic stenosis) | Rarely, orthostasis or hypotension | Microcytic anemia | Renal and liver function tests | Coagulation studies | Radionuclide scanning | CTA/MRA | Upper GI endoscopy and colonoscopy | Tortuous, dilated veins, venules and capillaries in the colonic mucosa and submucosa | Endoscopy |
