Study Notes
Upper GI Tract
- Consists of esophagus, stomach, and small intestine
- Common disorders: Gastroesophageal reflux disease (GERD), Peptic ulcer disease (PUD), Gastroenteritis
Esophagus
- Tube-like structure from mouth to stomach
- Two sphincters: Upper esophageal sphincter (UES) and Lower esophageal sphincter (LES)
Stomach
- Consists of fundus, body, and pylorus
- Two sphincters: LES and pyloric
- Phases: Cephalic (vagus nerve, acetylcholine), Gastric (HCl acid, pepsinogen, gastrin, intrinsic factor), Intestinal (small intestine sends signals to slow stomach emptying)
Small Intestine
- Consists of duodenum, jejunum, and ileum
- Lined with villi for absorption of nutrients
- Releases hormones: Cholecystokinin, secretin
- Ducts from liver and pancreas enter duodenum
- Enterohepatic circulation: bile acids from ileum to liver
Gastroesophageal Reflux Disease (GERD)
- Signs and symptoms: Dysphagia, Heartburn, Epigastric pain, Regurgitation, Dyspepsia
- Diagnosis: Endoscopy and manometry
- Treatment: Lifestyle changes, PPIs, antacids, Laparoscopic antireflux (fundoplication), Endoscopic radiofrequency delivery, LINX Reflux Management System
Hiatal Hernia
- Stomach pushes up through opening in diaphragm
- May be asymptomatic
- Signs and symptoms: Dysphagia, Epigastric discomfort
- Diagnosis: Endoscopy
- Treatment: PPIs, histamine-2 blockers, surgery
Pyloric Stenosis
- Constriction of pyloric sphincter
- Can be congenital
- Signs and symptoms: Gastroparesis, Projectile vomiting, Firm abdomen over pylorus
- Surgical repair needed
Acute Gastritis
- Inflammation of stomach lining
- Causes: Medications (aspirin, NSAIDs, corticosteroids), Infection, Acute stress, Bile reflux, Alcohol abuse
- Complaints: Heartburn, Epigastric pain
- Diagnosis: Endoscopy
- Treatment: Remove causative agents, PPIs, histamine-2 receptor antagonists
Chronic Gastritis
- Caused by Helicobacter pylori
- Treatment: Reduce acid levels and protect gastric lining, Antibiotic therapy, Lifestyle changes
Peptic Ulcer Disease (PUD)
- Treatment: Reduce acid levels and protect gastric lining, Antibiotic therapy, Lifestyle changes
- Therapeutic endoscopic treatment: Thermal coagulation therapy, Hemostatic clips, Fibrin sealant, Hemostatic nanopowder spray
- Surgical treatment: Vagotomy, Gastric drainage
Hernia
- Intestinal protrusion through abdominal wall
- More common in males
- Types: Inguinal (most common), Reducible, Incarceration, Strangulation
- Symptoms and severity depend on location and extent
- Diagnosis: Patient history and physical examination
- Treatment: Herniorrhaphy (hernia repair)
Gastroenteritis
- Irritation of lining of stomach, small or large intestine by pathogen or toxin
- Infectious microorganisms: Norovirus, Rotavirus, Shigella, E. coli, Giardia
- Transmitted person to person, water- or foodborne
- Increased fluid shift into lumen of intestine, resulting in diarrhea
- Damage of villi by pathogen or toxins
Celiac Disease
- Hypersensitivity reaction to gluten
- Gluten-derived protein (gliadin) causes symptoms
- Unknown cause; autoimmune disease
- Gluten ingestion results in bloating and gas
- Steatorrhea (loss of fat in stools) may develop
- Malnutrition is a concern
