Study Notes
Imaging Techniques
- Chest and Upper Abdomen Visualization: X-rays are commonly used for imaging these areas, providing a quick overview of potential issues.
- Virtual Colonoscopy: Utilizes CT or MRI scans to create detailed images of the colon.
Hiatal Hernia Repair
- Use of Carbon Dioxide Gas: Reduces risk of complications and allows for clearer visualization during laparoscopy.
- Types of Hiatal Hernias:
- Rolling (Paraesophageal) Hiatal Hernia: Characterized by a portion of the stomach rolling up alongside the esophagus.
Peptic Ulcer Disease
- Main Cause: Most commonly caused by Helicobacter pylori infection and the long-term use of NSAIDs.
Stomach Cancer
- Most Affected Area: Typically, the antrum (lower part) of the stomach is most commonly affected.
Positioning During Medical Procedures
- Enema Tube Insertion: The left lateral position is recommended for comfort and ease.
- Reflux accentuation: The supine position can enhance reflux and herniation during barium swallow studies.
Barium Enema
- Purpose: Used to visualize lower gastrointestinal (GI) tract abnormalities and detect issues like tumors or polyps.
Crohn’s Disease
- Main Cause: The exact cause remains unclear, but genetic, immune, and environmental factors play a role.
- Primary Involvement: Mainly affects the ileum, although it can occur anywhere in the GI tract.
- Difference from Ulcerative Colitis: Crohn's disease can affect any part of the GI tract and involves all layers of the bowel wall, while Ulcerative Colitis primarily affects the colon and rectum, limited to the mucosa.
Ulcerative Colitis
- Common Symptom: Characterized by bloody diarrhea.
Malabsorption Syndrome
- Causes: Can be caused by conditions like celiac disease, pancreatic insufficiency, and infections.
Intestinal Obstruction
- Mechanical Causes: Includes adhesions, hernias, and tumors.
- Closed Loop Obstruction: Notable for two ends of a segment being occluded, leading to increased pressure and risk of ischemia.
- Functional (Adynamic) Ileus: Marked by reduced or absent peristalsis and a uniformly dilated appearance on imaging.
Imaging Findings
- Distention of the Large Bowel: Characteristic appearance includes a "coffee bean" sign in cases of sigmoid volvulus.
- Pneumoperitoneum: Most commonly caused by perforation of hollow viscera.
Diverticular Disease
- Common Age Group: Primarily affects individuals over 40.
- Contributing Factors: Low-fiber diet, lack of exercise, and obesity can exacerbate the condition.
- Symptoms: Includes abdominal pain and changes in bowel habits.
- Surgical Recommendations: Surgery is often recommended for recurrent diverticulitis or complications like perforation.
- Preventive Diet: A high-fiber diet is advised to prevent flare-ups.
- Exercise Importance: Regular physical activity can help decrease the risk of diverticulitis.
Pancreatic Cancer
- Most Common Age Group: Typically diagnosed in individuals aged 65-80.
- Median Survival Untreated: Roughly 3-6 months.
- Improved Prognosis: Early detection and surgical resection significantly enhance survival rates.
- Treatment Options: Include surgery, chemotherapy, and palliative care.
Imaging Characteristics
- Significant Signs of Hiatal Hernia: Sliding hiatal hernia is indicated by the presence of a gastroesophageal junction above the diaphragm on imaging.
- Distention Appearance: The large bowel may show a "birds beak" sign in cases of volvulus.
Hypertrophic Pyloric Stenosis
- Affecting Muscle Layer: The muscularis externa layer of the pyloric canal is thicker with increased cell numbers.
- Surgical Procedure: Pyloromyotomy is performed to relieve the obstruction by widening the pyloric channel.
