Study Notes
Endoscopy and Diagnostic Tools
- Various endoscopic techniques include therapeutic and diagnostic procedures, essential for evaluating gastrointestinal disorders.
- Esophageal pH monitoring and manometry are critical for diagnosing gastroesophageal reflux disease (GERD).
- Endoscopic Retrograde Cholangiopancreatography (ERCP) aids in visualizing the bile duct and pancreas.
- Wireless video endoscopy utilizes a capsule that records data non-invasively on a belt, offering a comfortable alternative.
Salivary Gland Disorders
- Xerostomia refers to dry mouth due to decreased saliva, leading to oral burning and swallowing difficulties.
- Common causes include infections (like mumps), salivary calculi, and tumors.
Oral Cavity Conditions
- Aphthous ulcers are recurrent, painful lesions occurring in up to 20% of the population, particularly in women prior to menstruation.
- Stomatitis may arise from non-infective causes (trauma, vitamin deficiencies) or infections (herpes simplex, candida).
- Oral signs of systemic conditions include geographic tongue and atrophic glossitis.
Esophageal Anatomy and Function
- The esophagus measures approximately 25 cm and has upper (UES) and lower esophageal sphincters (LES) with high resting pressure to prevent reflux.
- Peristalsis involves primary and secondary contractions to move food while tertiary contractions may indicate dysfunction.
Symptoms of Esophageal Disorders
- Common symptoms include dysphagia (difficulty swallowing) and odynophagia (painful swallowing).
- Heartburn and regurgitation are key indicators of GERD, often exacerbated by dietary factors (fat, chocolate, alcohol).
Hiatus Hernia
- Hiatus hernia occurs when part of the stomach protrudes through the diaphragm, leading to reflux symptoms and reduced pressure gradients.
- Clinically significant features include regurgitation, choking, and atypical chest pain linked to esophageal spasms.
Complications of Esophageal Conditions
- Barrett's esophagus is a pre-malignant condition with a 40-120 fold increased relative risk of esophageal cancer, despite an absolute risk of only 0.1%-0.5% per year.
- Other complications include esophagitis and benign strictures, with rare occurrences of Cameron lesions in large hiatal hernias.
Investigative and Management Approaches
- In young patients without alarming features, empirical treatment often suffices.
- Endoscopic procedures can provide interventions for patients presenting with symptoms of fullness, nausea, or upper abdominal pain postprandially.
