UW Flashcards
guy has bubbles in his urine also has diverticulitis and UTI, this is most commonly due to diverticular disease and presents with pneumaturia (air) , fecaluria, or urinary tract infection. Abdominal CT scan with oral or rectal (not intravenous) contrast can confirm the diagnosis by showing contrast material in the bladder with thickened colonic and vesicular walls
**Colovesical fistula **
guy has has watery diarrhea and in past her had his cecum and lower small bowl removed, this can develop after ileocecal resection due to colonic bacteria entering the small intestine. The gold standard for diagnosis is* jejunal aspirate* with a quantitative culture of intestinal fluid; however, this test is invasive. Instead, SIBO can be confirmed with a carbohydrate breath test.
Small intestinal bacterial overgrowth (SIBO)
woman incsidntly found Dense mass in liver on CT with central scaring , asymptomatic, this is a benign liver lesion due to an aberrant congenital artery. It is usually found incidentally in young women and is marked by the presence of a stellate central scar and radiating fibrous bands.
Focal nodular hyperplasia
woman with Women on long-term oral contraceptives, what liver mass
Hepatic adenoma
livre mass with Acute or chronic liver injury (eg, cirrhosis)
Regenerative nodules
liver mass with Systemic symptoms
Chronic hepatitis or cirrhosis
Elevated ɑ fetoprotein
Hepatocellular carcinoma
inliver Single/multiple lesions
Known extrahepatic malignancy
Liver metastasis
this occurs when the cecum and ascending colon twist on their mesentery, forming a closed-loop obstruction. Progressive abdominal pain and distension, along with nausea/vomiting, are typical. Abdominal x-ray may reveal a large, dilated loop of colon.
Cecal volvulus
this (eg, due to malignancy) can cause abdominal distension and pain; however, x-ray typically reveals an enlarged gastric bubble with decompressed bowel distally.
Gastric outlet obstruction
can cause self-resolving episodes of abdominal pain and vomiting. However, because the mechanical obstruction occurs in the distal small bowel (ie, ileum), x-ray typically reveals multiple, dilated small-bowel loops
leocolic intussusception (prolapse of the ileum into the colon)
(intestinal obstruction due to dysfunctional peristalsis) typically causes generalized distension of the large and small bowel on x-ray.
Paralytic ileus
can cause colonic dilation on x-ray. However, x-ray typically reveals diffuse dilation of the colon within its normal anatomic arrangement rather than a single, dilated colonic loop, as in cecal volvulus. In addition, patients typically appear toxic (eg, fever, altered sensorium) and often have bloody diarrhea.
Toxic megacolon
is a life-threatening complication of esophageal instrumentation. Clinical presentation may include severe chest/back pain, fever, and a widened mediastinum on chest x-ray. Water-soluble contrast esophagography can confirm the diagnosis.
Esophageal perforation
Patients with this disease, especially those who have required intestinal surgery in the past, are at high risk for future complications and often need aggressive management with biologic and/or immunomodulator therapy. Smoking is strongly associated with increased severity and progression of this disease
severe Crohn
Rapid onset of periumbilical pain (often severe)
Pain out of proportion to examination findings
Hematochezia, risk factor are Atherosclerosis and Hypercoagulable disorders and Laboratory studies typically show leukocytosis, elevated hemoglobin, elevated amylase, and metabolic acidosis. we need to do Mesenteric angiography if diagnosis is unclear adn CT (ifpreferred)
Acute mesenteric ischemia
