Flexible fiberoptic colonoscopy is a safe and effective diagnostic tool for pediatric patients, particularly for evaluating inflammatory bowel disease and rectal bleeding. It offers high diagnostic accuracy and can change initial radiographic diagnoses.
Area of Science:
- Pediatric Gastroenterology
- Endoscopic Procedures
- Diagnostic Imaging
Background:
- Colonoscopy is an essential tool for diagnosing pediatric gastrointestinal conditions.
- Previous studies have established the utility of colonoscopy in adults, but data in pediatric populations are less extensive.
- Understanding the safety, efficacy, and diagnostic yield of pediatric colonoscopy is crucial for clinical practice.
Purpose of the Study:
- To review the utility and outcomes of flexible fiberoptic colonoscopies in pediatric patients.
- To compare the diagnostic accuracy of colonoscopy with barium enema in children.
- To assess the safety and complication rates of colonoscopy in this age group.
Main Methods:
- Retrospective review of 139 fiberoptic colonoscopies performed between 1975 and 1982 on 113 patients aged 1 month to 20 years.
- Procedures were performed under sedation (meperidine and diazepam) or general anesthesia.
- Indications included rectal bleeding, inflammatory bowel disease assessment, and evaluation of abdominal pain, diarrhea, or fever.
Main Results:
- The cecum was reached in 84% of diagnostic examinations.
- Colonoscopy findings agreed with barium enema in 46/75 patients, showed superiority in 25, and barium enema was superior in 4.
- Colonoscopy changed radiographic diagnoses in several cases and revealed greater extent of disease in others; 10/26 patients with polyps had bleeding significant enough to cause anemia. Five minor complications occurred, with no major complications.
Conclusions:
- Flexible fiberoptic colonoscopy and polypectomy are useful procedures in childhood when performed by experienced physicians.
- Colonoscopy is highly sensitive and accurate for evaluating colonic disease in children.
- Colonoscopy and barium enema are complementary, with barium enema often preceding colonoscopy, though exceptions exist.
Abstract:
A review was made of 139 fiberoptic colonoscopies performed between 1975 and 1982 on 113 patients aged 1 month to 20 years. General anesthesia was used in four procedures. All others were done under sedation with meperidine (mean dose 2.9 mg/kg) and diazepam (mean dose 0.5 mg/kg). Indications were rectal bleeding in 52 patients; assessment and surveillance of known inflammatory bowel disease in 33 patients; and diagnostic evaluation of abdominal pain, diarrhea, and/or fever in 28 patients. The cecum was reached in 84% of diagnostic examinations. Comparison of findings on colonoscopy with barium enema in 75 patients showed agreement in 46, colonoscopic superiority in 25, and barium enema superiority in four. Bleeding sufficient to cause anemia was seen in 10/26 patients with polyps. Five minor complications and no major complications occurred. Flexible fiberoptic colonoscopy and polypectomy may be done usefully in childhood by physicians well versed and experienced with these procedures. Colonoscopy and biopsy changed the radiographic diagnosis from ulcerative colitis to Crohn's disease in several cases and indicated greater extent of colonic disease in several cases of ulcerative colitis and Crohn's disease. Colonoscopy is usually the most sensitive and accurate diagnostic tool for the evaluation of colonic disease, but barium enema and colonoscopy are complementary tests and barium enema should usually precede colonoscopy, with certain exceptions.
