Abstract
The surgical treatment for Hirschsprung’s disease HD has changed in recent decades to reduce the need for extensive surgical dissections Independent of the technique used the surgery includes a colectomy of the aganglionic region beyond the transition zone The presence of ganglion cells in the intraoperative frozen sections determines the extension of the colonic segment to be resectedSince the first description of the transanal endorectal pullthrough TEPT technique by De la Torre and Ortega in 1998 this approach has become the method of choice for the treatment of HD In longaganglionic segment cases proximal to the descending colon the TEPT technique may require laparoscopic or laparotomy assistanceDetermining the location of the transition zone is an essential issue for surgical planning and is even more important during the TEPT procedure because it indicates the location from which biopsies should be taken for frozen pathological evaluation
