Children with single ventricle viscus sickness (SVCD) have poor growth in youth. Tube‐assisted feeding (TF) is employed to boost weight gain, however its impact on long‐term growth remains unknown. We tend to sought-after to match the longitudinal growth of SVCD patients receiving TF when initial viscus surgery with those fed entirely orally. A complete of 134 patients was included; sixty fourth were male and sixty eight underwent the Norwood operation. One third of patients (44) received TF. Adjusting for age, TF patients had a median of 0.56 lower weight‐for‐age z‐score (WAZ) than non‐TF patients (P = 0.007) through the age of half dozen years. Longitudinal height wasn't tormented by TF standing (P = 0.15). In an exceedingly sub analysis of Norwood patients, TF patients had lower WAZ at initial hospital discharge despite longer LOS. TF patients had diminished WAZ when adjusting for complications, interstage hospitalizations, and temporal arrangement of later operations.
