Are We Overdoing Pediatric Lower Gastrointestinal Endoscopy?

Area of Science:

• Pediatric Gastroenterology
• Diagnostic Endoscopy

Background:

• Lower gastrointestinal endoscopy (LGIE), including colonoscopy, is frequently used in children for rectal bleeding, abdominal pain, and diagnosing inflammatory bowel disease (IBD).
• However, the diagnostic yield for isolated symptoms like rectal bleeding and recurrent abdominal pain in otherwise healthy children is not well-established.

Purpose of the Study:

• To evaluate the indications and outcomes of pediatric lower gastrointestinal endoscopy.
• To identify potential strategies for optimizing the use of colonoscopy in pediatric patients.

Main Methods:

• A retrospective analysis of 999 pediatric lower gastrointestinal endoscopy/colonoscopy procedures performed between January 2001 and December 2010.
• Data collected included demographics, indications, findings, diagnoses, and complications.

Main Results:

• 39% of colonoscopies were normal. Suspected IBD was the most common indication (45%), with IBD confirmed in 63% of those cases.
• Rectal bleeding (20% of cases) and recurrent abdominal pain (5% of cases) had high rates of normal findings (72% and 100%, respectively).
• The procedure had a low perforation rate (0.2%) and a 52% cecal intubation rate.

Conclusions:

• Pediatric colonoscopy is safe but often yields normal results, suggesting potential overuse.
• Strategies like conservative management for anal fissures, fecal calprotectin screening for suspected IBD, and avoiding endoscopy for isolated recurrent abdominal pain could improve efficiency.
