@med.human: How Hirschsprung Disease Surgery Is Done (3D Animation) Hirschsprung disease surgery is performed to remove the portion of the colon that lacks nerve cells. The surgeon removes the affected segment and connects the healthy intestine to the anus in a pull-through procedure. This restores normal bowel movement by allowing stool to pass through properly innervated bowel tissue. #hirschsprungdisease #pediatricsurgery #colonsurgery #medical3d #3danimation
