GI / Nutritional Flashcards
Most common causes of appendicitis
- Fecalith (MC)
- Inflammation
- Malignancy
- Foreign Body
Vomiting usually occurs ________ pain in appendicitis
After
RLQ with LLQ palpation
Rovsing Sign
Appendicitis
RLQ pain with internal and external hip rotation with flexed knee
Obturator Sign
Appendicitis
RLQ pain with right hip flexion/extension (right leg against resistance)
Psoas Sign
Appendicitis
Diagnosis for appendicitis
- CT scan
- Ultrasound
- Leukocytosis
Otherwise healthy infant aged 2-3 months seems to be in pain, cries for more than 3 hours a day for more than 3 days a week, for more than 3 weeks
Colic
Severe paroxysmal crying that occurs mainly in late afternoon
Colic
Transient relaxation of LES leading to esophageal mucosal injury
GERD
Complications of GERD (4)
- Esophagitis
- Stricture
- Barrett’s esophagus
- Esophageal carcinoma
Sign/symptoms of GERD
- Heartburn (hallmark) - sometimes retrosternal and postprandial
- Regurgitation (acidic taste)
- Dysphagia, cough at night
Alarm symptoms of GERD
- Dysphagia
- Odynophagia
- Weight loss
- Bleeding (suspect malignancy)
Diagnosis of GERD
Clinical diagnosis
- Endoscopy often first
- Esophageal manometry
- 24 hour ambulatory pH monitoring - gold standard
Lifestyle modifications for GERD
Elevation of head of bed by six inches Avoid recumbency for three hours after eating Eat small meals Avoid certain foods Decrease fat and EtOH intake Weight loss smoking cessation
Pharmacological therapy for GERD
- Antacids and OTC H2 receptor antagonists
- PPI and prokinetic agents (cisapride)
- Nissen fundoplication if refractory
Dyssynergic defecation, slow transit, and IBS-constipation type
Primary causes of constipation
DM, hypothyroid, hypercalcemia, intestinal mass, Parkinson’s disease, anal stricture, and medications
Secondary causes of constipation
Alarm symptoms of constipation
- Hematochezia
- Weight loss
- Fam hx of colon CA
- Anemia
- Heme positive stools
- Severe persistent constipation
Diagnosis of constipation
- Rectal exam - r/o masses, fissures, sphincter tone
2. Colonoscopy if alarm sx
Treatment of constipation
- Increase fluids, exercise, develop bowel pattern
- Fiber of 25 g daily
- Bulk/osmotic laxatives
- Prunes are an alternative
Hypertrophy and hyperplasia of the muscular layers of the pylorus
Pyloric Stenosis
Most common cause of intestinal obstructioni n infancy
Pyloric stenosis
95% of pyloric stenosis present in the first ___________ of life, and the condition rarely presents after ____________
3-12 weeks
> 6 months
Physical exam signs of pyloric stenosis
Signs of dehydration/malnutrition
Hypochloremic metabolic acidosis
Jaundice
Olive-shaped, nontender, mobile, hard pyloric
Diagnosis of pyloric stenosis
- Ultrasound - first line
2. Upper GI contrast (string sign)
Treatment of pyloric stenosis
- Rehydration
2. PYloromyotomy
Intestinal segment invaginates/telescopes into adjoining intestinal lumen, leading to bowel obstruction
Intussusception
Most patients with intussusception are between ______________ of age
6-18 months
Intussusception most commonly occurs at the:
Ileocolic junction
Intussusception often occurs after:
Viral infection
Lead points for intussusception
- Meckel diverticulum
- Enlarged mesenteric lymph node
- Hyperplasia of peyer’s patches
- Benign/malignant tumor
- Henoch-schonlein purpura
- Foreign body
Classic triad of intussusception
- Vomiting
- Abdominal pain
- Passage of blood per rectum “currant jelly stool”
Physical exam of intussusception
“Dance’s Sign”
Sausage-shaped mass in RUQ or hypochondrium and emptiness in RLQ
Diagnosis of intussusception
Barium contrast enema (often diagnostic and therapeutic)
Radiographs - lack of gas in the bowels
Management of intussusception
Barium or air insufflation
Hydration (IV fluids)
Surgical resection if refractory
Congenital absence of ganglion cells leading to functional obstruction
Hirschsprung disease
Hirschsprung disease occurs most commonly in the:
Distal colon and rectum (75%)
Increased incidence of hirschsprung disease in:
Males and down syndrome
