Study Notes
Dysphagia
- Dysphagia categorized into solid food only and solids and liquids.
-
Solid food only:
- Intermittent: Esophageal ring causes.
- Progressive:
- With heartburn: Peptic stricture.
- Without heartburn: Linked to old age or carcinoma.
-
Solids and liquids:
- Intermittent: Chest pain associated with Diffuse Esophageal Spasm (DES).
- Progressive:
- With heartburn: Scleroderma.
- Without heartburn: Nocturnal symptoms indicate achalasia, a condition of lack of relaxation.
- Mechanical causes of dysphagia include benign/malignant strictures, esophageal webs/rings, diverticula, hernias, and inflammatory conditions.
- Functional causes include achalasia, scleroderma, and DES.
- Oropharyngeal dysphagia often results from neurological deficits (e.g., ALS, diabetic neuropathy, MS).
Esophagitis
- Inflammation of the esophageal mucosa categorized as:
- GERD: Acid-related damage.
- Medication-associated: Certain antibiotics and NSAIDs.
- Infectious: Cytomegalovirus, herpes, candidiasis.
- Eosinophilic: Antigen sensitivity, notably in young white males.
- Symptoms include painful swallowing (odynophagia), dysphagia, heartburn, and retrosternal pain.
- Diagnosis confirmed via endoscopy.
- Management tactics vary based on cause including:
- GERD: Reflux treatments.
- Medication: Adjustments.
- Infectious: Antimicrobial therapy.
- Eosinophilic: PPIs, steroids.
- Major complications include recurrence leading to esophageal stricture.
Gastritis
- Inflammation of gastric mucosa, often infectious; Helicobacter Pylori is the most common cause.
- Autoimmune gastritis more prevalent in women; other less common causes include Crohn's, IBS, and ischemic conditions.
- Primarily affects the antrum of the stomach, notably impacting mucus cells.
- Causes encompass:
- Increased gastrin production.
- Epithelial cell injury.
- NSAIDs, alcohol, autoimmune diseases.
- H. pylori can create toxins leading to cell injury.
- Acute gastritis characterized by inflammation and increased acid secretion.
- Chronic gastritis leads to gland atrophy and metaplasia, decreasing acid and intrinsic factor production, increasing risk for cancer and MALT lymphoma.
- Symptoms include heartburn, iron deficiency, and cognitive decline.
- Diagnosis aided by CBC, stool tests, endoscopy, and breath tests.
- Treatment involves avoiding irritants, PPIs, and antibiotics as needed.
Esophageal Motility Disorders
- Disorders like diffuse spasm, scleroderma, and achalasia cause esophageal dysphagia.
- Spasms characterized by hyperdynamic, non-propulsive contractions due to various factors like decreased nitric oxide and inflammation.
- Presentation can vary from asymptomatic to intermittent dysphagia or chest pain, exacerbated by temperature changes.
- Diagnosis through manometry showing increased pressure contractions and barium swallow displaying corkscrew patterns.
- Management options include peppermint oil, calcium channel blockers, PPIs, and localized botulinum injections for severe cases.
Scleroderma
- An autoimmune disorder causing esophageal atrophy, scarring, and decreased lower esophageal tone.
- Characterized by diminished peristalsis and massive reflux.
- Diagnosed with AntiSci70 test, where 95% of CREST patients test positive.
- Includes features like calcinosis, Raynaud's, esophageal dysmotility, sclerodactyly, and telangiectasia.
- Treatment involves immunosuppression, PPIs, endoscopic dilation for strictures, and surgical fundoplication if necessary.
Achalasia
- Characterized by degeneration of ganglion cells, leading to esophageal dysfunction and diminished peristalsis.
- Lower esophageal sphincter fails to relax, leading to megacolon and regurgitation of undigested food.
- Diagnosed via barium swallow showing "bird beak sign."
- Management includes muscle fiber stretching techniques like balloon dilation, botulinum toxin, oral nitrates, and calcium blockers.
Esophageal Carcinoma
- Eighth most prevalent cancer; sixth leading cause of cancer death, more common in males.
- Two primary types:
- Squamous cell carcinoma: prevalent globally, linked to diet.
- Adenocarcinoma: more common in the U.S., associated with Barrett’s esophagus.
- Symptoms: bleeding, dysphagia, significant weight loss, iron deficiency, and pain (odynophagia).
- Diagnosis involves barium swallow, endoscopy, and biopsy.
- Treatment focuses on early detection for surgical resection, chemotherapy, and palliative care options.
Gastroesophageal Reflux Disease (GERD)
- Symptoms: esophagitis, chest pain, heartburn, regurgitation, cough, dysphagia.
- Water brash due to hypersalivation from gastric contents reflux.
- Diagnostic methods include symptom evaluations and potential endoscopy if treatment fails.
- 24-hour pH monitoring can indicate acid reflux.
Esophageal Tears and Perforations
- Includes Mallory-Weiss Syndrome and Boerhaave’s Syndrome; more common in males.
- Often linked to alcohol use; tears account for 10-15% of upper GI bleeds.
- Symptoms can range from asymptomatic to chest/epigastric pain, often post-vomiting.
- Diagnosis often confirmed through symptoms and endoscopy.
- Management involves fluids, transfusion, and specialized tubes for pressure.
Peptic Ulcer Disease
- Most ulcers occur in the duodenum; major cause is H. pylori infection.
- Other factors: NSAIDs, corticosteroids, smoking, and chronic diseases.
- Gastric ulcers occur primarily in the lesser curvature of the stomach, while duodenal ulcers are more common.
- Symptoms include epigastric pain, nausea, and possible occult bleeding.
- Diagnosis through EGD can reveal ulcers; treatment includes lifestyle modifications, PPIs, and antibiotics.
Gastric Cancer
- Third most common cancer death, particularly prevalent in Eastern Asia and Eastern Europe.
- Associated risk factors: nitrosamines, genetics, H. pylori, longstanding gastritis.
- Intestinal gastric carcinoma presents as nodular; diffuse is infiltrative with poor prognosis.
- Presentation includes epigastric discomfort, nausea, weight loss, and potential hematemesis.
