[Risk factors for delayed bleeding after intestinal polypectomy in children]

Area of Science:

• Pediatric Gastroenterology
• Surgical Oncology
• Clinical Research

Context:

• Intestinal polyps are common in children, necessitating effective and safe removal procedures.
• Delayed bleeding is a potential complication following endoscopic polypectomy, requiring careful management.
• Understanding risk factors is crucial for optimizing treatment strategies and patient outcomes.

Purpose:

• To identify clinical characteristics and risk factors associated with delayed bleeding after intestinal polypectomy in pediatric patients.
• To establish a predictive model for delayed bleeding using clinical and procedural variables.
• To provide evidence-based guidance for surgical intervention in pediatric intestinal polyp cases.

Summary:

• A retrospective analysis of 2,456 children undergoing endoscopic high-frequency electrocoagulation loop resection for intestinal polyps was performed.
• Delayed bleeding occurred in 3.22% of cases, with significant associations found for endoscopic operation time, polyp diameter, and resection method.
• Multivariate logistic regression and ROC curve analyses confirmed these factors as predictors of delayed bleeding.

Impact:

• The study highlights that endoscopic high-frequency electrocoagulation loop resection is associated with a low incidence of delayed bleeding in children.
• Identified risk factors (operation time, polyp diameter, resection method) can inform clinical decision-making and potentially reduce complication rates.
• Findings contribute to the theoretical basis for clinical surgical intervention of intestinal polyps in pediatric populations.
