What is the appropriate aganglionic bowel length on contrast enema for attempting single stage transanal endorectal pull-through in Hirschsprung disease?

This study establishes surgical planning criteria for single-stage transanal endorectal pull-through in Hirschsprung disease, finding that aganglionic bowel length under 52 cm on contrast enema and patient age over 10 months predict successful single-stage repair without laparoscopic assistance. The research addresses the significant discrepancy between radiologic and pathologic measurements of affected bowel length.
