Study Notes
Gastroenterology Lecture Notes
- The lecture covered topics in gastroenterology.
- The team members included Daniela Dobru (course coordinator); Danusia Onisor; Adina Andone; Crina Pop; and Andrei Ioanovici.
- The timetable for Module 2 (2023/2024) outlined the daily schedule of lectures, electives, and internships.
- Subjects included a holistic approach to neuroimmunology, preventive cardiology, and imaging diagnosis in patients with gastroenterological disorders.
- Internships in gastroenterology and nephrology were also part of the schedule.
- Specific topics within the module included Barrett's esophagus, dyspeptic syndrome, gastritis, peptic ulcers, diarrhea, constipation, inflammatory bowel disease, colorectal cancer, chronic pancreatitis, gall bladder disease, chronic viral hepatitis, and cirrhosis.
- Evaluation included a practical exam (30%), a theoretical exam (50%), and attendance at clinical presentations.
- Minimum performance standards for the course were listed.
Gastroesophageal Reflux Disease (GERD)
- GERD is a condition where stomach contents return into the esophagus.
- Frequent symptoms and damage to the esophagus or respiratory system.
- Etiology includes: functional or mechanical problems of the lower esophageal sphincter (LES); excessive acid or bile reflux; specific foods (coffee, alcohol, chocolate, fatty meals); and medications (beta-agonists, nitrates, calcium channel blockers, anticholinergics, hormones like progesterone, and nicotine).
- Additional factors contributing to GERD symptoms or injury: transient lower esophageal sphincter relaxations (TLESRs); hiatal hernia; poor acid clearance from the esophagus; diminished salivary flow; reduced mucosal resistance to injury; increased acid production; delayed gastric emptying of solids; and obstructive sleep apnea.
- Hiatal hernias can contribute to reflux by issues with LES movement and length of the high-pressure zone (HPZ).
- Types of hiatal hernias exist (sliding, rolling, mixed).
- Diagnostic tests are sometimes unnecessary depending on the patient's symptoms and history.
Diagnostic Tests
- Investigations for GERD are warranted in patients with alarm symptoms, inconclusive trial results, or unusual symptoms.
- Mandatory tests include upper GI endoscopy (confirming complications, evaluating anatomy).
- Optional tests include 24-hour pH probe testing (confirming diagnosis with unclear history or atypical symptoms), and upper GI series (delineating anatomy and gastric emptying).
- During endoscopy, characteristic findings include linear erosions in the distal esophagus.
- Different grades of esophageal lesions are assessed.
Management of GERD
- Treatment approaches followed stepwise to manage GERD, with goals including symptom control, healing of esophagitis, and prevention of complications.
- Treatment strategy is based on lifestyle modifications, medication use (antacids, H2RAs, PPIs), and surgical interventions (corrective antireflux surgery).
- Factors used in determining treatment type are duration and frequency of symptoms; quality and timing of symptoms; alcohol and tobacco use; dietary choices; current medications; and other present conditions.
Special Populations
- Specific treatment approaches for infants (supportive therapy, diet modifications and postural management)
- Treatment for pregnancy (antacids)
- Management of the elderly (emphasis on endoscopy and avoiding prokinetics for diagnosis and treatment.)
Refractory Reflux
- A case with symptoms that do not respond to standard proton pump inhibitor (PPI) treatment.
Barrett's Esophagus and Esophageal Cancer
- Diagnosis: Distal esophagus lined with columnar epithelium (minimum 1 cm), presence of specialized intestinal metaplasia (histologically).
- Associated risk factors: chronic GERD, advancing age, male gender, obesity, alcohol and nicotine exposure.
- Prevalence has increased (likely due to improved diagnostic technology)
Pathophysiology
- Barrett's esophagus is an acquired disorder where columnar epithelium replaces the normal squamous epithelium in the distal esophagus.
- Pathophysiology is linked to chronic reflux of gastric contents.
- Classic presentation includes older white males with long-standing GERD and obesity.
Surveillance Guidelines
- Biopsy specimens are collected from every quadrant at 2-cm intervals along the esophageal segment.
- Focal lesions (nodules and ulcerations) are important indicators for further evaluation
- High-Grade Dysplasia (HGD) triggers specific management options (observation, endoscopic mucosal resection, photodynamic therapy, or esophagectomy).
- Low-Grade Dysplasia (LGD) intervention is less intensive following a 6-month observation period.
Treatment Options
- Treatment for complications of GERD may include surgical interventions as corrective anti-reflux surgery.
- Options range from radiofrequency ablation, cryotherapy, endoscopic mucosal resection (EMR), to esophagectomy depending on specific diagnosis and severity.
