Esophageal Disorders Flashcards
Hiatal Hernia
Diaphragmatic hernia, esophageal hernia
Herniation of portion of stomach into esophagus through an opening in diaphragm
Most common abnormality found on upper GI x-ray
Sliding Hiatal Hernia
Stomach slides through opening with pt is supine, goes back into abdominal cavity when pt is standing upright
Most common type
Paraesophageal Hiatal Hernia
Esophogastric junction remains in place but fundus and greater curvature of stomach roll up through diaphragm
Acute parasophageal hernia is a medical emergency
Causes of hiatal hernia
Many factors
Structural changes, weaken diaphragm muscles
Increased intraabdominal pressure (obesity, pregnancy, heavy lifting)
Hiatal hernia clinical manifestations
May be asymptomatic
Heartburn
Dysphagia
Hiatal hernia complications
GERD Esophagitis Hemorrhage from erosion Stenosis Ulcerations of herniated portion Strangulation of hernia Regurgitation with tracheal aspiration Increased risk of respriatory problems
Hiatal hernia lifestyle modifications
Eliminate alcohol Elevate HOB Stop smoking Avoid lifting/straining Reduce weight, if appropriate Use antisecretory agents and antacids
Hiatal Hernia Surgical Therapy
Reduction of herniated stomach
Herniotomy (excision of hernia sac)
Herniorrhaphy (closure of hiatal defect)
Gastropexy (antireflux procedure)
*Laparoscopically: Nissen or Toupet techniques used
*Thoracic or open abdominal used depending on individual pt
Gastropexy
Attachment of the stomach supdiaphragmatically to prevent reherniation
Nissen Fundoplication
Fundus of stomach is wrapped around distal esophagus, fundus is then stuffed into itself
Esophageal Cancer
Malignant neoplasm of esophagus
Comes from structural changes
\
Squamous Cell
Changes due to damage that leads to cancer
Adenocarcinomas
Arise from glands lining esophagus
Resemble cancers of stomach and small intestine
Risk factors for esophageal cancer
Smoking Excessive alcohol intake Barrett's metaplasia Central obesity History of achalasia
Barrett’s metaplasia
Seen in long term bulimics and long term GERD
