[Advantages and limits of rigid rectosigmoidoscope and flexible colonoscope in childhood]
Insights
Pediatric proctosigmoidoscopy and colonoscopy yield similar diagnostic rates. Colonoscopy offers higher histological confirmation, but shorter procedures are preferred due to common lower tract pathology in children.
Area of Science:
- Pediatric Gastroenterology
- Endoscopy
- Colorectal Surgery
Context:
- Rigid proctosigmoidoscopy and colonoscopy are diagnostic tools for pediatric lower gastrointestinal issues.
- Over a decade, 220 proctosigmoidoscopies and 71 colonoscopies were performed in children.
Purpose:
- To compare the diagnostic yield and limitations of rigid proctosigmoidoscopy versus colonoscopy in pediatric patients.
- To analyze indications and outcomes for these endoscopic procedures in pediatric populations.
Summary:
- Both proctosigmoidoscopy and colonoscopy achieved 81% positive diagnoses.
- Colonoscopy provided superior histological confirmation (85%) compared to proctosigmoidoscopy (51%).
- Pediatric endoscopy predominantly uses shorter instruments due to prevalent lower tract pathology and rarity of extensive neoplastic lesions.
Impact:
- Colonoscopy is an increasingly valuable complementary tool for pediatric colonic pathology.
- Understanding the strengths of each endoscopic method optimizes diagnosis in pediatric patients.
- This analysis informs procedural choices for pediatric lower gastrointestinal evaluations.
Abstract:
During the past ten years 220 pediatric proctosigmoidoscopies with the rigid instrument in 182 infants and children, and 71 colonoscopies in 62, were performed. Advantages and limits of these two instruments are discussed. The indications and results of the different procedures are presented. Positive diagnoses were obtained in 81% with both techniques while the histological examination was positive in 85% of specimens obtained by colonoscopy and only in 51% of the proctosigmoidoscopical ones. Colonoscopy has increasingly became a complementary method for colonic pathology in children, in comparison with adult medicine, however, pediatric indications have been handled mostly with the shorter instrument for two main reasons: 1) Pediatric colonic pathology affects predominantely the lower tract; 2) Neoplastic lesions, in which total colonoscopy with biopies at different levels is mandatory, are extremely rare in children.
