 narrowing of the esophagus(distal) near the junction with the stomach (squamocolumnar jxn).  sequelae of gastroesophageal reflux– induced esophagitis. (GERD) ~10%

 “Chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus”

 Decreased basal lower esophageal sphincter (LES) pressure and LES relaxations allow refluxate to enter esophagus  Decreased acid clearance allows acidic refluxate to remain in the esophagus  Refluxate of acid and pepsin injures the esophageal mucosa  Decreased basal lower esophageal sphincter (LES) pressure and LES relaxations allow refluxate to enter esophagus  Decreased acid clearance allows acidic refluxate to remain in the esophagus  Refluxate of acid and pepsin injures the esophageal mucosa

 Heartburn  Regurgitation of sour materials  Heartburn  Regurgitation of sour materials

 Barium esophagram  Endoscopy  Esophageal manometry  24 hour pH monitoring

 Goals:  Relieve dysphagia and restore swallowing  Treat the underlying GERD  promote healing of esophagitis  prevent stricture recurrence

 Stricture Dilatation  Initial means of relieving dysphagia.  Dysphagia resolves when the stricture can be dilated to 14 mm  Esophageal resection  Patients with undilatable strictures Kahrilas P J. Gastroesophageal reflux disease. JAMA. (1996); 276: 983–988. [PubMed]PubMed

 Antacids  Widely used to self-medicate for heartburn  Useful in treating mild GERD

 Anti secretory Agents  PPI (Proton Pump Inhibitors)  Specifically inhibit the H + /K + -ATPase enzyme system at the secretory surface of the gastric parietal cell, resulting in a potent antisecretory effect  Promotes healing of erosive esophagitis in chronic GERD  omeprazol (20mg/d)  lansoprazole(30 mg/d)  pantoprazole (40 mg/d)  esomeprazole (40 mg/d)  rabeprazole (20 mg/d)

 Anti secretory Agents  H 2 -receptor antagonists  competitive antagonists of histamine at the parietal cells H 2 receptor, suppressing the normal secretion of acid by parietal cells and the meal-stimulated secretion of acid.  cimetidine, 300 mg  ranitidine, 150 mg bid  famotidine, 20 mg bid  nizatidine, 150 mg bid

 Antireflux Surgery  Fundoplication (laparoscopic; open surgery)  gastric fundus (upper part) of the stomach is wrapped, or plicated, around the lower end of the esophagus and stitched in place  Increases LES pressure  alleviates chronic heartburn in people whose condition cannot be controlled by either lifestyle changes or medication

 Weight reduction  Head elevation during sleep  elimination of factors that increase abdominal pressure.  Abstinence from smoking and alcohol  Avoid fatty foods, coffee, chocolate, mint, orange juice
