Transnasal endoscopy (TNE) was first developed in Milwaukee, WI. Children’s Wisconsin is one of a few centers in the nation that can offer upper endoscopy without sedation. TNE is an unsedated procedure that allows your child’s doctor to examine and collect biopsies, or tissue samples, of your child’s esophagus, stomach and small bowel.

They care for every aspect of a child's health, including their physical, social, dental and mental well-being.
