What is dyspepsia? Picture credithttp://blog.givelify.com/wp-content/uploads/2014/07/Princess_Bride_That_Word.jpg

Functional dyspepsia “presence of symptoms thought to originate in the gastroduodenal region, in the absence of any organic, systemic, or metabolic disease” Rome III diagnostic criteria (at least 1 of) Bothersome postprandial fullness Early satiation Epigastric pain Epigastric burning No evidence of structural disease

Functional dyspepsia Differential diagnosis Functional (nonulcer) dyspepsiaUp to 70 percent Peptic ulcer disease15 to 25 percent Reflux esophagitis5 to 15 percent Gastric or esophageal cancer< 2 percent Abdominal cancer, especially pancreatic cancerRare Biliary tract diseaseRare Carbohydrate malabsorption (lactose, sorbitol, fructose, mannitol)Rare Gastroparesis Rare HepatomaRare Infiltrative diseases of the stomach (Crohn disease, sarcoidosis)Rare Intestinal parasites (Giardia species, Strongyloides species)Rare Ischemic bowel diseaseRare Medication effects (Table 3)Rare Metabolic disturbances (hypercalcemia, hyperkalemia)Rare PancreatitisRare Systemic disorders (diabetes mellitus, thyroid and parathyroid disorders, connective tissue disease)Rare Loyd RA and McClellan DA.

Upper gastrointestinal alarm symptoms ● Age ≥55 years with new onset dyspepsia ● Chronic gastrointestinal bleeding ● Dysphagia ● Progressive unintentional weight loss ● Persistent vomiting ● Iron deficiency anaemia ● Epigastric mass ● Suspicious barium meal result taken from National Institute for Health and Care (formerly Clinical) Excellence referral guidelines for suspected cancer

Functional dyspepsia treatment Diet and lifestyle – weight loss – smoking and alcohol cessation – Avoid certain foods (e.g., fatty foods) Medication – acid suppression therapy (e.g., PPIs) – H. pylori eradication therapy – prokinetic drugs (e.g., metoclopramide, cisapride, domperidone) – antidepressants and psychologic therapies Alternative therapies (e.g., accupuncture) Ford AC.

What is GERD? Picture credithttp://blog.givelify.com/wp-content/uploads/2014/07/Princess_Bride_That_Word.jpg

Definition “GERD should be defined as symptoms or complications resulting from the reflux of gastric contents into the esophagus or beyond, into the oral cavity (including larynx) or lung. GERD can be further classified as the presence of symptoms without erosions on endoscopic examination (nonerosive disease or NERD) or GERD symptoms with erosions present (ERD).” Katz et al, Guidelines for the diagnosis and management of gastroesophageal reflux disease. Am J Gastroenterol 2013; 108:308 – 328.

Peptic ulcers can be deadly Rudyard Kipling J. R. R. Tolkien James Joyce

Ulcer complications ● bleeding ● perforation ● penetration

Management of acute bleeding from a peptic ulcer Clinical status At presentation ● Assess hemodynamic status (pulse and blood pressure, including orthostatic changes). ● Obtain complete blood count, levels of electrolytes (including blood urea nitrogen and creatinine), international normalized ratio, blood type, and cross-match. ● Initiate resuscitation (crystalloids and blood products, if indicated) and use of supplemental oxygen. ● Consider nasogastric-tube placement and aspiration; no role for occult-blood testing of aspirate. ● Consider initiating treatment with an intravenous proton-pump inhibitor (80-mg bolus dose plus continuous infusion at 8 mg per hour) while awaiting early endoscopy; no role for H2 blocker.† ● Perform early endoscopy (within 24 hours after presentation). ● Consider giving a single 250-mg intravenous dose of erythromycin 30 to 60 minutes before endoscopy. ● Perform risk stratification; consider the use of a scoring tool (e.g., Blatchford score16 or clinical Rockall score17) before endoscopy. At early endoscopy Perform risk stratification; consider the use of a validated scoring tool (e.g., complete Rockall score17) after endoscopy.
