BACKGROUND: The hypothesis was that ultra-high-frequency (UHF) ultrasound can distinguish ganglionic from aganglionic bowel during surgery for Hirschsprung disease. The aim was to assess UHF ultrasound for differentiating ganglionosis from aganglionosis in children undergoing rectosigmoid Hirschsprung disease surgery. METHODS: The child's intestine …

BACKGROUND: Developing new diagnostic imaging methods that provide detailed visualization of the histoanatomy of tissues and organs requires precise histomorphometric evaluation. With a particular focus on bowel, this study aimed to develop and validate a computer program for reliable and efficient assessment …

Background/Objectives: Intraoperative frozen biopsies are essential during surgery for Hirschsprung’s disease (HD). However, this method has several limitations with the need for a faster and real-time diagnostic alternative. For this, consistent histoanatomical and morphometric differences between aganglionic and ganglionic bowel must be …

To make surgery more precise and to shorten anesthesia-times for children undergoing surgery for Hirschsprung's disease, ultra-high frequency ultrasound (UHFUS) has been suggested to replace peroperative biopsy. The study's aim was to determine quantitatively whether aganglionic and ganglionic bowel segments could be …

Abstract Introduction Hirschsprung’s disease (HD) is characterized by aganglionosis in the bowel wall, requiring resection. Ultra-high frequency ultrasound (UHFUS) imaging of the bowel wall has been suggested to be an instantaneous method of deciding resection length. The aim of this study was …

Ultra-high-frequency ultrasound (UHFUS) has a reported potential to differentiate between aganglionic and ganglionic bowel wall, referred to as histoanatomical differences. A good correlation between histoanatomy and UHFUS of the bowel wall has been proven. In order to perform more precise and objective …

It has been shown that ultra-high frequency (UHF) ultrasound applied to the external bowel wall can delineate the histo-anatomic layers in detail and distinguish normal bowel from aganglionosis. This would potentially reduce or lessen the need for biopsies that are currently mandatory …
