    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.
