Hirschsprung disease (HSCR) is a disorder caused by the failure of neural crest migration leading to an aganglionic colon and functional obstruction. Transabdominal Yancey-Soave pull-through is one of the definitive therapies for this condition. Prognostic factors, including sex, aganglionosis type, age at definitive surgery, nutritional status, eosinophilia and lymphocytosis, might influence the outcomes of the pull-through. We evaluated the functional outcomes of HSCR patients after Yancey- Soave surgery and associated them with the prognostic factors.The study included Hirschsprung patients aged ≥3 and 0.05).Our study shows that eosinophilia and lymphocytosis might not affect the functional outcome of patients with HSCR following Yancey-Soave surgery. In addition, sex, aganglionosis type, age at definitive surgery and nutritional status might not influence the functional outcome after definitive surgery. Further, a more extensive study is essential to clarify our findings.
