Gastrointestinal Tract Diseases

  1. 1. Artesia Fistulae Stenosiscauses the esophagus an abnormal a gradual narrowing to end in a blind- connection (fistula) of the tube that ended pouch rather between the carries food to the than connecting esophagus and the stomach. It occurs normally to the trachea when scar tissue stomach. builds up in the tube.
  2. 2. a defect or hole in the diaphragm thatallows the abdominal contents to move into the chest cavity
  3. 3. Types Bladder Cardiac Colonic Kommerell Duodenal and Jejunal Epiphrenic Gastric Killian-JamisonMeckels - a true congenital diverticulum, is a smallbulge in the small intestine present at birth. It is avestigial remnant of the omphalomesenteric duct(also called the vitelline duct or yolk stalk), and is the most frequent malformation of the gastrointestinal tract Rokitansky-Aschoff Traction esophageal Urethral Zenker’s
  4. 4. a condition that causes severe projectile non-bilious vomiting in the firstfew months of life. There is narrowing (stenosis) of the opening from the stomach to the first part of the small intestine known as the duodenum,due to enlargement (hypertrophy) of the muscle surrounding this opening(the pylorus, meaning "gate"), which spasms when the stomach empties.
  5. 5. dilatation and hypertrophy of the colon Hirschsprung disease Acquired Toxic a disorder of the gut which colonic enlargement an acute form of colonic is caused by the failure of associated with chronic distension. It is the neural crest cells to constipation, but with characterized by a very migrate completely during normal ganglion cell dilated colon (megacolon), fetal development of the innervation. accompanied by abdominal intestine, eventually distension (bloating), and forming Auerbachs plexus sometimes fever, abdominalThe affected segment of the pain, or shock. colon fails to relax, causing an obstruction
  6. 6. The earliest stools of an infant. Unlike later feces,meconium is composed of materials ingested duringthe time the infant spends in the uterus: intestinal epithelial cells, lanugo,mucus, amniotic fluid, bile, and water.
  7. 7. It is characterized by incomplete LESrelaxation, increased LES tone, and lack of peristalsis of the esophagus (inability ofsmooth muscle to move food down the esophagus)
  8. 8. Gastroesophageal refluxdisease (GERD) is a condition in which the stomachcontents (food or liquid) leakbackwards from the stomachinto the esophagus (the tube from the mouth to the stomach). This action can irritate the esophagus,causing heartburn and other symptoms.
  9. 9. Normal tissue lining the esophagus -- the tube that carries food from the mouth to the stomach -- changes to tissue that resemblesthe lining of the intestine. About 10%-15% of people with chronic symptoms of GERD develop Barretts esophagus.
  10. 10. a type of chronic stomach inflammation due to the action of the immune system against stomach tissue and its components. It causes destruction of the stomach tissue with progressive atrophy of the stomach. AKA Autoimmune atrophic gastritisAutoimmune metaplastic atrophic gastritis
  11. 11. Stomach polyps Mass of form incells that response form on tothe inside inflamma of the tion or stomach other making damage polyps. to the lining of the stomach.
  12. 12. Any blockage or narrowing of the arteries feeding blood to the bowels can result in ischemic bowel disease. Possible blockages include tumors andblood clots, while the narrowing happens through a process called atherosclerosis. Atherosclerosis begins when the arterys inner wall becomes damaged. Possible culprits include smoking, infection, diabetes and high blood pressure. The arterial wall will try to repair itself, but in theprocess cholesterol builds up on the arterys inside surface. As this "plaque" becomes thicker, the artery becomes narrower and blood flow is reduced. It is at this point that ischemic bowel syndrome enters the picture.
  13. 13. A small vascular malformation of the gut. It is a common cause of otherwise unexplainedgastrointestinal bleeding and anemia. Lesionsare often multiple, and frequently involve thececum or ascending colon, although they canoccur at other places. Treatment may be with endoscopic interventions, medication, or occasionally surgery.
  14. 14. a condition characterized by inflammation of the appendix. It is classified as a medicalemergency and many cases require removal of the inflamed appendix, either by laparotomy or laparoscopy. Untreated, mortality is high, mainly because of the risk of rupture leading to peritonitis and shock.
  15. 15. an inflammation of the peritoneum, the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs. Peritonitis may be localized or generalized, and may result from infection (often due to rupture of a hollow organ as may occur in abdominaltrauma or appendicitis) or from a non-infectious process.
