Abstract
Purpose
To describe symptoms, diagnostic features, treatments, and outcomes of pneumatosis intestinalis (PI) in pediatric patients being treated for acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).
Methods
This retrospective chart review included 514 patients ≤18 years of age diagnosed with ALL or AML between January 1999 and December 2007. PI episodes were identified by radiology report reviews.
Results
Twenty patients with ALL and four patients with AML presented 31 PI episodes. The median time between diagnoses of leukemia and PI was 1.0 month (interquartile range 0.8–6.4 months). Plain radiographs diagnosed all PI episodes. Computerized tomography (CT) and ultrasound were performed in 6 and 13 episodes, respectively. All CT and three ultrasounds demonstrated PI. Thirty episodes occurred exclusively in the colon, most commonly in the ascending (n = 26) and transverse (n = 18) segments. Treatment included complete bowel rest in 27 (87.1%) and intravenous broad-spectrum antibiotics in 29 (93.5%). One case required colectomy. Two episodes were untreated. There were no fatalities associated with PI.
Conclusions
PI is uncommon in children with ALL or AML. Ultrasound is less sensitive than plain radiographs for diagnosis. PI occurred almost exclusively in the colon. With conservative management, most patients had excellent outcome.
