Esophagus What is Esophagitis? Inflammatory changes to the lining of the esophagus (squamous epithelium) Esophagitis Symptoms: Dysphagia Chest Pain Odynophagia Causes: GERD (#1) Radiation Pills Caustic Ingestion Eosinophilic Infiltration Infection Diagnostic Tests: Gold Standard: Endoscopy Bravo Study: Ambulatory Esophageal pH Infectious Esophagitis: THINK Immunocompromised! Agents that can cause esophagitis due to mucosal injury: Bisphosphanates Aspirin Iron salts NSAID’s Potassium chloride tablets Quinidine Tetracycline There are various scales available to quantify esophagitis severity. The Hetzel-Dent scale utilizes a rating of 0 to 4, with 0 indicating no abnormalities and grade 4 indicating deep peptic ulcerations or confluent erosions involving more than 50% of the mucosal surface of the distal 5 cm of esophageal squamous mucosa CMV (Chemo/HIV) Ganciclovir (5mg/kg IV q 12 hours x 3-6 weeks) Candida Fluconazole 100mg/d P.O. x 1421 days Suspect in patients w/ DM or recent steroid or ABX treatment Herpetic Acyclovir 400mg 5x daily for 10 days Famciclovir 500mg BID or Valacyclovir 500mg BID x 10 days Eosinophilic Esophagitis: Affects children to adults 20-40 y.o Males > females (3:1) History of allergies, eczema, asthma or GERD is common “Feline esophagus” on EGD Often causes solid food dysphagia due to esophagitis and Trachealisation – “Feline Esophagus” dysmotility CBC w/ diff. reveals eosinophilia – systemic response to something allergic Consider checking tTG for celiac disease and consider food allergy testing Treat acid suppression aggressively with PPI b.i.d. For 68 wks and may consider Montelukast (Singulair) 10mg daily or Budesonide susp 1mg B.I.D. Achalasia: Idiopathic motility disorder involving loss of peristalsis in the distal 2/3 of smooth muscle and impaired relaxation of LES. Likely the result of neuronal abnormalities Dysphagia (solids & liquids), Chest Pain, Weight loss Age 25 and greater Also consider Scleroderma or late stage Chagas’ disease (South American Trypanosomiasis) Esophageal Varices: Dilated submucosal veins that develop in patients with underlying Portal Hypertension / Cirrhosis and may result in serious upper GI bleeding in 1/3 of patients. Usually occurs in distal 5 cm of esophagus Higher mortality rate than any other source of UGI bleeding. Identified via upper endoscopy Actively Bleeding Treatment = ABC’s, page GI or Surgery stat Management: Emergency stabilization (fluids IVs etc) Treat underlying coagulopathy (if present) Endoscopy with banding or injection sclerotherapy Balloon tamponade (if hemorrhage is too vigorous) Mallory-Weiss Tear: Non-penetrating mucosal tear at the GE junction caused by retropulsion of the gastric cardia into the chest during repeated vomiting/retching ~ 5% of GI bleeds Small, fresh hematemesis Common in young adults or those with history of ETOH abuse Diagnosis is confirmed endoscopically (EGD) Boerhaave’s Syndrome: Caused by a sudden increase in intraesophageal pressure + negative intrathoracic pressure caused by straining or vomiting. Tear most often occurs @ left posterolateral aspect of the distal esophagus and can extend several centimeters. Often associated with alcoholism or hx. of peptic ulcer disease Can lead to Mediastinitis GERD: Also known as Pyrosis or old fashioned “heartburn” Refers to backflow of gastric acid and/or duodenal contents (bile acid) into the esophagus and past the LES (lower esophageal sphincter) without associated belching or vomiting. Affects 20% of adults who report at least weekly episodes, 10% of adults report daily heartburn. Symptoms: History of vomiting or retching followed by acute, severe retrosternal chest and upper abdominal pain. Odynophagia Fever Cyanosis Shock Pathophysiology: 1. Impaired acid neutralization by saliva and HCO3 2. Impaired esophageal motility 3. LES (inappropriate relaxation) 4. Hiatal hernia 5. Delayed gastric emptying (Gastroparesis) Typical (Esophageal) Clinical Presentation: Heartburn *classic* Bitter taste in the throat Acid regurgitation Risk Factors: Obesity Delayed gastric emptying Pregnancy Systemic sclerosis Hiatal hernia Recumbency Smoking Alcohol use Medication such as CCB’s, nitrates, Theophylline Consuming large meals (within 3 hours before bedtime) – one of the main things that will help with nocturnal reflux Wearing tight belts Foods: chocolate, coffee, peppermint, or fatty food, garlic Dysphagia Odynophagia Waterbrash Atypical (Supraesophageal) Presentation: Chest pain Laryngitis (Hoarseness) Asthma Sinusitis Chronic cough Aspiration pneumonia Tooth decay Recurrent sore throat Frequent throat clearing Globus sensation Treatment: Antacids (Tums, Rolaids) neutralize secreted HCl H2-receptor antagonists (H2RAs) block the histamine receptor, interfering with one of the stimulation pathways Proton pump inhibitors (PPIs) block acid at its source in the proton pump of the parietal cell. (1st Line) Omeprazole (Prilosec) 20 mg Lansoprazole (Prevacid) 15 to 30 mg Rabeprozole (Aciphex) 20mg Pantoprozole (Protonix) 40mg Esomeprazole Magnesium (Nexium) 40mg Omeprazole w/Sodium Bicarb (Zegerid) 40mg Dexlansoprazole (Dexilant) 60mg Side Effects of PPI’s: HA, diarrhea, nausea Prokinetic drugs (Zelnorm, Reglan) Antireflux surgery (Nissen Fundoplication) Esophagitis secondary to GERD: Severe Reflux from GERD (incompetent LES) can lead to esophagitis. Diagnostic Histology: Intraepithelial Eosinophils The severity of symptoms is not related to the degree of histologic esophagitis Consequences: bleeding, stricture, Barrett esophagus Treatment: Lifestyle modification elevate head of bed, no bedtime snacks no smoking/alcohol decrease meal size and fat intake avoid caffeine (chocolate, coffee, tea, cola) peppermint, citrus fruit Medications – antacids, H2 receptor blockers, proton pump inhibitors Barrett’s Esophagus: A self-protective mechanism by which squamous epithelium in the distal esophagus is replaced by columnar epithelium (gastric). 3 types of gastric columnar epithelium, **Intestinal metaplasia is the type that increases the risk of adenocarcinoma. Secondary to chronic refluxinduced injury – compensation by the body but this causes a lot of cellular turnover Affects ~ 10,000 people per year in U.S. 5 year survival rate < 15% if you have adenocarcinoma Pay attention to GERD complaints in old, white males with truncal obesity. (Sutton’s Law) “Tongue” of Barrett’s Treatment: long-term PPI therapy and adherence to anti-reflux measures Advised to have repeat endoscopic surveillance at 2 to 3 year intervals Incidence of Barrett’s evolving into esophageal adenocarcinoma is 2 in 200. Squamous Cell Esophageal Cancer: Blacks > whites Most prevalent worldwide Associated with: ETOH Tobacco abuse Human Papilloma Virus > 50% involve distal third of esophagus Overall 5- year survival rate is < 15% for either form of Esophageal Cancer Adenocarcinoma Esophageal Cancer: Prominent in whites Incidence rising Associated with Obesity Most cases arise from Barrett’s changes and chronic GERD Involves distal third of esophagus Overall 5- year survival rate is < 15% for either form of Esophageal Cancer More Nodular: More Spread out: Esophageal Web: A thin, diaphragm-like membrane of squamous mucosa Mid to upper esophagus May be multiple Congenital or may be related to Plummer – Vinson Syndrome Plummer-Vinson Syndrome: Predominately in Caucasians Female > male; 40-70 years old Esophageal “Schatzki Rings” Smooth, circumferential and thin mucosal structures found at the GE junction (distal). Lead to dysphagia Strongly associated with Hiatal Hernias Suspected secondary to GERD Treatment = Esophageal Dilation Esophageal Strictures: Most found in mid to distal esophagus Majority result from chronic inflammation and GERD Usually benign Can be associated with Barrett’s Esophagus May also be caused by burns Pills that got stuck and disintegrated the tissue Predominant findings are dysphagia with a history of iron-deficiency anemia. Treatment: Esophageal Dilation Balloon Method: Maloney-Dilator Method: Zenker’s Diverticulum: Protrusion of pharyngeal mucosa @ PE junction (posterior protrusion most common). Caused by loss of elasticity of UES Usually older patients Symptoms: Halitosis Dysphagia Nocturnal Choking Diagnosis: Barium Swallow Tx: Surgery Benign Esophageal Tumor: Leiomyoma The most common Submucosal, nodular lesions Most are asymptomatic, although larger lesions can cause dysphagia. Endoscopic ultrasonography** is test of choice because endoscopic biopsies are generally Stomach Peptic Ulcer Disease: Include both Gastric and Duodenal ulcers ~ 10% of adults develop PUD in their lifetime Epigastric Pain (dyspepsia) often described as gnawing, dull, “hunger-like” discomfort. Most common cause of Upper GI bleeding Duodenal Ulcers 5x more common, younger patients Pain relieved with food or antacids, recurs 2-4 hours after a meal, or a strong nocturnal component (3) major causes : NSAIDS – inhibit prostaglandin synthesis. Prostaglandins are known to increase mucosal blood flow, increase bicarb and mucous secretion and stimulate mucosal repair. Aspirin is the most ulcerogenic NSAID (beware of BC, Goody’s powders and Alkaseltzer). H. pylori – gram neg. bacillus that resides in the mucous gel coating the epithelial cells of the stomach. Suspected to cause a defect in protective barrier that can then lead to chronic gastritis and ulcer formation. Zollinger-Ellison (ZE) syndrome – benign gastrin-secreting tumor Gastric Ulcers more common in ages 55-70 , high association with cancer Pain aggravated by food and associated with weight loss and “fear of eating” Associated symptoms: Nausea, Anorexia, Abdominal bloating, vomiting, melena, weight loss, hematemesis usually located in the pancreas or duodenal wall that results in uninhibited secretion of gastrin (Hypersecretion) and constant acid production. Leads to development of peptic ulcers in 90% of patients; diarrhea is common. < 1% of PUD is caused by ZE syndrome, may be associated with MEN type 1 Complications: Perforation Diagnosis: Upper Endoscopy with biopsy is diagnostic test of choice. CBC, BUN if suspected GI bleeding. H.pylori serology gives limited information for active involvement of H.pylori. Need gastric biopsy to confirm active infection. Consider checking a fasting serum Gastrin level if peptic disease is persistent (to r/o ZES). Need to stop PPI therapy before testing. Management: Pharmacotherapy is directed at reduction of acid secretion, preserving mucosal defenses, and eradication of H.pylori infection. Proton pump inhibitors are currently the treatment of choice for PUD, given their high safety and efficacy profile. Combination antibiotic regimens with PPI are most effective in eradicating H.pylori. Regular, well balanced diets with elimination of caffeine, sodas, acidic foods, NSAID’s, ETOH and smoking. Gastritis: superficial inflammation and erosions of gastric mucosa without penetration into the submucosa or muscularis. Patients are usually asymptomatic but can progress to dyspepsia, anorexia, nausea and vomiting. Accounts for < 5% of GI bleeds. Acute Gastritis: NSAIDs Biphosphonates Potassium Macrolides ETOH Stress Viruses Bacteria Chronic Gastritis: Helicobacter pylori Autoimmune Lymphocytic Bile Reflux Eosinophilic Gastric Cancer: Most neoplasms of the stomach are malignant and most of those are adenocarcinoma. Adenocarcinoma of the stomach is the 2nd most frequent cause of cancer world-wide. Incidence has declined in Westernized countries; attributable to improved diet and refrigeration (has eliminated the need for salting, smoking, preserved foods.) Commonly associated with: NSAID’s Prolonged stress (physiologic) due to severe medical or surgical illness Heavy ETOH consumption Caffeine abuse, and H.pylori. ** Psychological Stress Diagnosis: Endoscopy with biopsies for H.pylori. Treatment: Proton Pump inhibitors and cessation of offending medication, ETOH, or caffeine.
