Upper gastrointestinal fiberoptic endoscopy in pediatric patients

Area of Science:

• Pediatric Gastroenterology
• Endoscopic Procedures
• Gastrointestinal Diagnostics

Background:

• Pediatric patients with gastrointestinal symptoms often require endoscopic evaluation.
• Traditional radiographic studies have limitations in diagnosing certain upper gastrointestinal conditions in children.
• Advancements in endoscopic technology aim to improve diagnostic yield and patient comfort.

Purpose of the Study:

• To evaluate the diagnostic efficacy of endoscopy in pediatric patients with various gastrointestinal complaints.
• To compare the performance of different endoscopic prototypes in visualizing specific upper gastrointestinal regions in children.
• To assess the effectiveness and safety of sedation and anesthesia protocols for pediatric endoscopy.

Main Methods:

• 163 endoscopic procedures were performed on 142 pediatric patients aged 1 month to 20 years.
• Patients presented with symptoms including chronic abdominal pain, nausea, vomiting, dysphagia, odynophagia, retrosternal pain, hematemesis, and melena.
• Comparison of diagnostic findings between endoscopy and radiographic studies was conducted. Specific endoscope models (GIF-P2, GIF-P1, CF-P, GIF-D) and sedation regimens were utilized.

Main Results:

• Endoscopy identified the source of symptoms in a higher percentage of patients compared to radiographic studies for chronic abdominal pain (21/66 vs. 15/66), nausea/vomiting/dysphagia (19/31 vs. 14/31), and upper GI bleeding (26/34 vs. 4/28).
• The GIF-P2 prototype demonstrated superior visualization of the esophagus, stomach, and duodenum in patients under 10 years old, including infants as young as 3-5 kg.
• Functional abdominal pain was the most common diagnosis for chronic abdominal pain. Foreign bodies were removed, and caustic ingestions were identified. Sedation with diazepam and meperidine was effective in school-aged children, while general anesthesia was preferred for younger children.

Conclusions:

• Pediatric endoscopy is a highly effective tool for diagnosing upper gastrointestinal disorders, surpassing radiographic methods in sensitivity for conditions like bleeding and pain.
• The GIF-P2 endoscope offers enhanced visualization in younger pediatric patients, facilitating better examination of the upper gastrointestinal tract.
• Appropriate sedation and anesthesia management are critical for the safety and success of endoscopic procedures in the pediatric population.
