Introduction: Recently, management of anorectal malformation (ARM) emphasis on good intestinal functional outcomes after definitive procedure. This study analyzed the patients’ outcomes following operation related with the predictive variables. Methods: We applied the Krickenbeck classification and Rintala scoring system to define ARM type and functional outcomes, respectively. Results: This study ascertained 72 patients: 38 males and 34 females. According to Rintala scoring system, 94.4%, 90.2%, 60%, 83.3%, and 60% patients showed no soiling, no constipation, ability to hold back defecation, defecation frequency of every other day to twice a day, and feels/reports the urge to defecate, respectively. In addition, none of patients had either accident or social problem. Rintala score of normal and good have been shown in 14 (19.4%) and 55 (76.4%) patients, respectively. Female patients had a 4.2-times higher risk for showing a more/less often frequency of defecation compared with male patients (95% confidence interval (CI)=1.03-17.1; p=0.035). Conclusions: ARM patients’ functional outcomes after procedure in our institution are considered relatively good. In addition, the frequency of defecation in male patients after definitive surgery is better than female patients.
