ABSTRACT

BACKGROUND: Ileocolic intussusception is considered a pediatric emergency, with concerns for risk of significant morbidity in children with a prolonged intussusception state. Emergent therapy is standard of care, as prior studies have shown poor outcomes in patients with long delays (> 24 h) before intervention. Various factors can result in shorter delays, and there are limited studies evaluating outcomes in these patients. This study aimed to determine if there were differences in reduction success rates associated with short in-hospital time delays. OBJECTIVE: This study is to determine enema success rate and morbidity in patients with documented time delays between intussusception diagnosis and therapeutic enema. MATERIALS AND METHODS: A retrospective evaluation of pediatric patients with intussusception at a single children's hospital between 2007 and 2019 was performed. Patient's records were reviewed for time of symptom onset, radiologic diagnosis, and attempted enema. Ultrasounds and radiographs were reviewed for bowel obstruction, free peritoneal fluid, trapped fluid around the intussusceptum, and absent bowel wall perfusion. Patients were evaluated for efficacy of reduction attempt, requirement for surgical reduction, and complications including bowel resection and bowel perforation. RESULTS: There were 175 cases of ileocolic intussusception requiring enema reduction. Successful reduction occurred in 72.2% (13/18) of cases performed within 1 h of diagnosis; 74.3% (78/105) between 1 and3 h; 73.2% (30/41) between 3 and 6 h; and 81.2% (9/11) with greater than 6 h. Need for bowel resection was not associated with short delays between diagnosis and reduction attempts (p = .07). CONCLUSIONS: There was no difference in intussusception reduction efficacy or complication rate in patients with increasing time between imaging diagnosis of ileocolic intussusception and reduction attempt, including delay intervals up to 8 h.

ABSTRACT

Myositis ossificans is a benign, ossifying, soft-tissue pseudotumor that most commonly occurs in men ages 30-40 years after trauma. Myositis ossificans may also occur in children, but it is extremely rare in those younger than 10 years of age. While myositis ossificans can often mimic malignant soft-tissue tumors, it has many unique findings that can aid in diagnostic differentiation. This differentiation is critical to avoid unnecessary risk with potentially harmful procedures. We present a very unusual presentation of myositis ossificans in the immediate post-birth perinatal period, as well as a review of key imaging findings.
