Study Notes
Disorders of the Gastrointestinal Tract
- Anorexia, loss of appetite, vomiting, constipation, diarrhea, abdominal pain, and evidence of gastrointestinal bleeding are clinical manifestations of many gastrointestinal disorders.
- Vomiting involves forceful stomach emptying via esophageal reverse peristalsis. It's often preceded by nausea and retching, except in projectile vomiting which directly stimulates the vomiting center.
- Constipation is categorized as functional (low-residue diet), slow-transit (impaired colonic function), or pelvic floor dyssynergia-anismus. Secondary constipation arises from neurogenic, drug-related, endocrine/metabolic issues, or obstruction.
- Diarrhea can be osmotic (excessive fluid draw), secretory (excessive fluid secretion), or motility-related (excessive motility).
- Abdominal pain can be visceral (originating from organs) or parietal (originating from peritoneum) due to stretching, inflammation, or ischemia.
- Gastrointestinal bleeding can manifest as hematemesis, melena, or hematochezia. Occult bleeding needs tests for detection.
- Dysphagia is difficulty swallowing, caused by mechanical or functional esophageal obstruction. Achalasia is a functional dysphagia related to esophageal innervation and relaxation loss.
- Gastroesophageal reflux disease (GERD) is chyme regurgitation into the esophagus, causing esophagitis from acidic gastric content exposure.
- Hiatal hernia is the stomach protruding through the esophageal opening of the diaphragm.
- Gastroparesis is delayed gastric emptying without mechanical obstruction. Pyloric obstruction arises from narrowings or blockages of the pylorus.
- Intestinal obstruction prevents normal chyme movement, often due to torsion, herniation, or tumors (mechanical). Paralytic ileus causes functional obstruction. Severe consequences include fluid loss, hypovolemia, shock, necrosis, and perforation.
- Gastritis is acute or chronic gastric mucosa inflammation. Regurgitation of bile, anti-inflammatory drugs, alcohol, infection (H. pylori), and some system diseases are associated.
- Chronic fundal gastritis is rare, with autoimmune response against parietal cells leading to gastric atrophy and pernicious anemia. Chronic antral gastritis is frequent, related to H. pylori and NSAIDs. Alkaline reflux gastritis arises from bile and pancreatic secretion reflux into the stomach.
- Peptic ulcers are mucosal inflammation and ulceration due to high gastric acid secretion or barrier disruption. Duodenal, gastric, and stress ulcers are the types, often associated with H. pylori and NSAIDs. Duodenal ulcers occur near the duodenum, generally with rapid gastric emptying, and resolve with food or antacids. Gastric ulcers commonly occur in the antrum.
- Zollinger-Ellison syndrome causes chronic gastric acid secretion and ulcers due to gastrinoma.
Other Disorders
- Stress ulcers (acute mucosal damage) result from severe illness, trauma, neural injury, or burns.
- Postgastrectomy syndromes are post-surgical complications.
- Malabsorption syndromes comprise impaired nutrient digestion or absorption. Pancreatic insufficiency is associated with inadequate digestive enzyme production. Lactase deficiency inhibits lactose digestion, causing osmotic diarrhea. Bile salt deficiency may prevent fat absorption, resulting in fatty stools.
- Ulcerative colitis is an inflammatory bowel disease causing colonic and rectal mucosal ulceration, frequent relapses. Crohn's disease involves the entire GI tract, often with skip lesions and granulomas. Microscopic colitis is chronic inflammation affecting microscopic levels of the colon. Irritable bowel syndrome (IBS) is a brain-gut interaction disorder with altered bowel habits.
- Diverticula are sac-like outpouchings in the colon wall. Diverticulosis is their presence, and diverticulitis involves inflammation. Appendicitis is obstruction causing inflammation and potential complications.
- Vascular insufficiency in the intestines arises from insufficient blood flow due to mesenteric vessel occlusion leading to ischemia and necrosis with symptoms including abdominal pain, fever, bloody diarrhea, hypovolemia, and shock.
- Portal hypertension, ascites, hepatic encephalopathy, jaundice, and hepatorenal syndrome are complications from liver disorders. Portal hypertension is high portal venous pressure due to resistance. Ascites is fluid build-up in the peritoneal cavity. Hepatic encephalopathy arises from unmetabolized toxins (ammonia) by the impaired liver. Jaundice is yellowing due to elevated bilirubin.
- Various hepatitis types cause liver inflammation (necrosis, Kupffer cell hyperplasia, infiltration). Fulminant hepatitis is a severe and often fatal complication of hepatitis B or C infection.
- Cirrhosis is an irreversible liver disease characterized by fibrosis, and nodular regeneration that leads to impaired function. Alcoholic liver disease arises from acetaldehyde-induced impairment of hepatocyte function. Non-alcoholic fatty liver disease represents fat build-up in hepatocytes and can advance.
- Primary biliary cirrhosis damages intrahepatic bile ducts through inflammatory destruction. Secondary biliary cirrhosis arises from bile duct obstruction. Primary sclerosing cholangitis involves fibrosis of medium and large bile ducts.
- Cholelithiasis involves gallstone formation (cholesterol or pigmented stones). Cholecystitis is related to gallstone-induced gallbladder inflammation. Acute pancreatitis is serious inflammation frequently due to biliary obstruction or alcohol. Chronic pancreatitis is recurrent inflammation usually related to alcoholism or recurrent acute pancreatitis.
- Cancers of the esophagus, stomach, colon, rectum, gallbladder, and pancreas are discussed, along with their risk factors and symptoms.
