Study Notes
Upper GI Pathology
- Upper GI system encompasses the organs from the mouth to the duodenum.
- Learning objectives include clinical presentations of upper GI diseases, characterizing the upper GI system, and introducing diseases of the esophagus, stomach, and duodenum.
Upper GI System
- Duodenoyeyunal flexure (Angle of Treitz): The junction of the duodenum and jejunum.
- Suspensory muscle of the duodenum (Treitz ligament): Anatomical structure in this region.
- Duodenum blockage: Potentially occurs due the superior mesenteric artery.
Clinical Manifestations
- Bleeding: A symptom associated with upper GI diseases.
- Obstruction: Characterized by vomiting without abdominal distension, often involving acid and bile.
- Acid and bile: Found in vomitus in certain cases of upper GI obstruction.
Diagnostic Implications
- Upper GI endoscopy: Diagnostic tool for upper GI pathology.
- ERCP (Endoscopic Retrograde Cholangiopancreatography) and ultrasonography: Used in conjunction with endoscopy for comprehensive assessment.
Mouth
- Inflammatory conditions: Gingivitis, dental caries, glossitis, tonsilitis, pharyngitis, and parotiditis.
- Infections and other factors: Infections, radiation exposure, and autoimmune diseases can cause mouth inflammation.
- Motor impairment: Difficulties with chewing and swallowing (dysphagia).
- Neuropathies, myopathies and Collagenopathies: Related to nerve, muscle or connective tissue diseases.
- Salivation disturbances: Disruptions in saliva production, often linked to inflammation, obstructions or tumors.
- Neoplasms: Epidermoid carcinoma, lymphoma, Kaposi's sarcoma are potential cancers affecting the mouth.
Esophagus
- Inflammations (esophagitis): Infections, radiation therapy, and autoimmune disorders often lead to esophageal inflammation.
- Motor impairment: Affecting swallowing (dysphagia), often due to conditions involving nerves, muscles or connective tissue.
- Neoplasms: Epidermoid carcinoma, adenocarcinoma, and lymphoma are examples of esophageal cancers.
- Anatomical alterations: Fistulas, atresia, and perforations can be present in the esophagus.
- Tumors and cysts: Malignant and benign lesions in the esophagus.
Dysphagia
- Oropharyngeal dysphagia: Issues with initial stages of swallowing (movement coordination, swallowing initiation, choking, and aspiration).
- Esophageal stenosis: Difficulty swallowing, progressing from solids to liquids, and resulting in food retention and regurgitation.
Esophago-gastric Junction
- Achalasia: Condition impacting the lower esophageal sphincter (LES).
- GERD (Gastroesophageal reflux disease): Stomach contents returning to the esophagus, leading to symptoms like heartburn and regurgitation.
- Hiatal hernia: Passage of abdominal contents through the esophageal hiatus; can produce GERD-like symptoms.
- Cancer: Cancers impacting the esophagogastric junction
Achalasia
- Reduced ganglionic cells in LES: Leading to hypertonic LES.
- Progressive dysphagia: Swallowing difficulty worsening over time.
- Esophageal dilation: Enlargement of the esophagus.
- Diagnosis: Manometry, biopsy
- Treatment: Dilatation, sphincterotomy
GERD
- Hypotonic LES: Lower esophageal sphincter doesn't function effectively, allowing stomach contents to reflux.
- Symptoms: Heartburn, regurgitation, and nonspecific symptoms.
- Esophagitis and Barrett's esophagus: Inflammation and precancerous changes in the esophagus.
- Diagnosis: pH monitoring, endoscopy
- Treatment: Medications (PPIs), dietary changes, fundoplication
Hiatal Hernia
- Passage of abdominal contents through esophageal hiatus: Portion of stomach protruding into the chest.
- Types of hiatal hernias: Sliding, paraesophageal, and mixed.
- Symptoms: Can cause GERD-like symptoms; symptoms may depend on the type of hernia.
- Diagnosis: Upper endoscopy, gastrointestinal transit studies.
- Treatment: Medications, dietary changes, fundoplication.
Cancer
- Neoplasms (cancers) in the esophagus and stomach: Epidermoid carcinoma, adenocarcinoma.
- Symptoms: Obstruction, weight loss, and distant disease.
- Diagnosis: Endoscopy and imaging techniques assessing distant disease.
- Treatment: Surgery, chemotherapy, radiation therapy, and palliative care.
Stomach
- Inflammations (Gastritis): Acute or chronic conditions, including infections, drug reactions, and autoimmune diseases can all lead to gastric inflammation.
- Motor impairment (Gastroparesis): Slowed emptying of the stomach, causing symptoms like nausea, vomiting, and early satiety (feeling full quickly).
- Neoplasms: Adenocarcinoma, GIST (Gastrointestinal stromal tumor) and MALT (mucosa-associated lymphoid tissue).
- Anatomical alterations/ulcers: Ulcers of the stomach lining.
- Pyloric obstruction: Blockage of the stomach opening (pylorus) to the small intestine.
Gastroparesis - Causes and Diagnosis
- Defective gastric emptying without physical obstruction: Stomach cannot empty properly.
- Types of gastroparesis: Primary (related to gastric pacemaker dysfunction), secondary (due to autonomic nerve dysfunction, muscular disorders, medications).
- Diagnostic tests: History, physical examination, motility studies like gastric emptying tests.
Acute and chronic Gastritis
- Acute gastritis: Sudden inflammation of the stomach, often caused by NSAIDs, alcohol, or infections like H. pylori.
- Chronic gastritis: Long-term inflammation, can be associated with autoimmune conditions or persistent infections.
- Pernicious anemia: Deficiency in Vitamin B12.
- Menetrier's disease: Characterized by inflammation.
- Specific systemic diseases: e.g Crohn's disease
Helicobacter pylori (H. pylori)
- Gram-negative spiral bacteria: Causes gastritis.
- Adhesion proteins: Aid bacterial attachment to gastric mucosa.
- Urease enzyme: Facilitates bacterial survival in the stomach's acidic environment.
- Toxins: GagA, VacA cause inflammation.
- Pathology: Acute and chronic gastritis, peptic ulcers, and stomach cancer.
Peptic Ulcer
- Duodenal ulcers: Most frequent type.
- Gastric ulcers: Occur later in life; often asymptomatic.
- Clinical manifestations: Epigastric pain or discomfort (often relieved by food).
- Diagnosis: Endoscopy.
Complications of Peptic Ulcer
- Perforation: A serious complication, potentially fatal.
- Outlet obstruction: Narrowing of the pyloric opening.
- Bleeding: Significant blood loss, potentially life-threatening.
- Penetration and fistulas: Perforation of adjacent organs leading to an abnormal connection or fistula.
Upper GI Bleeding
- Most common GI emergency: Represents a significant clinical concern.
- Mortality: Can range from 10%.
- Causes: Varices (due to liver disease), peptic ulcers, hiatal hernias, gastric cancers, and vascular malformations.
- Clinical manifestations: Hematemesis (vomiting blood), melena (black, tarry stools), hematochezia (bright red blood in stools), and cardiovascular compromise.
- Management: Endoscopy, resuscitation, surgical interventions (e.g., Sengstaken-Blakemore tube), and consideration of liver transplantation in certain cases.
