Study Notes
Congenital Abnormalities
- Congenital GI disorders often necessitate evaluation of associated organ abnormalities.
- Oesophageal atresia involves the absence or closure of a natural passage, commonly leading to feeding regurgitation after birth.
- Associated conditions include congenital heart defects, genitourinary malformations, and neurologic diseases.
- Oesophageal atresia results in mechanical obstruction with proximal and distal pouches connecting to the pharynx and stomach.
- Fistula complications may include aspiration, suffocation, pneumonia, and severe fluid imbalances.
- Hiatal hernias may present as congenital in infants or acquired later in life, causing symptoms akin to gastroesophageal reflux disease (GERD).
Oesophageal Obstruction
- Proper swallowing involves coordinated peristaltic contractions; dysmotility can disrupt this.
- Nutcracker oesophagus presents as high-amplitude contractions leading to potential obstruction.
- Diffuse oesophageal spasm causes functional obstruction and may lead to diverticula formation.
- Oesophageal stenosis often results from inflammatory scarring, commonly due to chronic reflux or irradiation.
- Dysphagia due to stenosis progresses from solids to liquids, often leading to dietary modifications.
Oesophageal Mucosal Webs and Rings
- Mucosal webs are uncommon projections often seen in women over 40, associated with conditions like gastroesophageal reflux and iron-deficiency anemia.
- Most commonly found in the upper oesophagus, webs cause dysphagia with incompletely chewed food.
- Schatzki rings are thicker, circumferential lesions that may lead to obstruction, treated with myotomy or balloon dilation.
Oesophageal Varices
- Oesophageal varices arise from portal hypertension, caused by liver diseases such as cirrhosis, particularly related to alcohol use.
- Varices develop from collateral channels due to impaired blood flow, leading to a venous plexus in the distal oesophagus.
- Ruptured varices cause massive hematemesis, presenting a medical emergency.
Oesophageal Lacerations
- Mallory-Weiss tears are longitudinal lacerations near the gastroesophageal junction, often related to severe vomiting or alcohol intoxication.
- These lacerations account for up to 10% of upper GI bleeding; they usually heal quickly without surgical intervention.
Oesophagitis
- Chemical oesophagitis results from irritation by substances like alcohol, hot fluids, or medicines lodging in the oesophagus.
- Infectious oesophagitis can occur in immunocompromised individuals, commonly caused by herpes simplex, CMV, or fungi.
Reflux Oesophagitis
- Reflux oesophagitis is mainly caused by gastroesophageal reflux disease (GERD), affecting adults over 40 and presenting with dysphagia, heartburn, and regurgitation.
- Contributing factors include decreased lower oesophageal sphincter tone and increased abdominal pressure from obesity, pregnancy, or hiatal hernias.
- Barrett oesophagus, a complication of chronic GERD, presents intestinal metaplasia, which raises adenocarcinoma risk, predominantly in white males aged 40-60.
Barrett Oesophagus Morphology
- Recognizable by red, velvety mucosa patches extending from the gastroesophageal junction, alternating metaplastic and normal mucosa.
- Sub-classified as long segment (>3 cm) or short segment based on the extent of the affected area.
