ABSTRACT
This chapter explains the key principles in the management of complex pediatric colorectal diagnoses. It provides case-based presentations, radiographic images, and operative images with multiple choice questions to test knowledge. The position of the anus in the female infant seems to be a source of uncertainty in the pediatric surgical field. The labia and tissue lateral to the anus are flattened in order to see the anatomy better. The perineal body is adequate and the anus is positioned within the sphincter complex. By performing the maneuver, it is easier to establish the size of the perineal body. On initial examination, the perineal body appears short, but when the buttocks are separated, the perineal body is shown to be of an adequate size. The anus is then calibrated with increasing size of Hegar dilator and confirmed to be of an adequate size.
