Single-stage versus multi-stage pull-through for Hirschsprung's disease: practice trends and outcomes in infants.

Purpose: The aim of this study was to evaluate surgical treatments and outcomes in a multi-institutional cohort of neonates with Hirschsprung's disease (HD).

Methods: Using the Pediatric Health Information System (PHIS) from 1999 to 2009, neonates diagnosed with HD were identified and classified as having a single stage pull-through (SSPT) or multi-stage pull-through (MSPT). Diagnosis and classification algorithms and clinical variables and outcomes were validated by multi-institutional chart review.

Sentinel lymph node biopsy in pediatric soft tissue sarcoma patients: utility and concordance with imaging.

Background: The purpose of this study was to report our experience with sentinel lymph node biopsy (SLNB) for pediatric soft tissue sarcomas to add to the limited literature about its feasibility, utility, and concordance with pre-operative imaging, including CT and (18)F-FDG PET (PET) scanning.

Methods: Medical records of patients with a sarcoma who underwent SLNB as part of their treatment for a soft tissue sarcoma at our institution from 2000 to 2011 were identified and reviewed.

Results: Eight patients underwent SLNB for soft tissue sarcoma during the study period.
