Electrophysiological Activity of the Anorectum in Children Suspected of Hirschsprung Disease

January 20, 2015 updated by: Naftali Freud, Rabin Medical Center

The Elactrophysiological Response of the Colon, in Normal Bowel, and Large Bowel Lacking Ganglia in Children With Suspected Hirschsprungs Disease.

Children with chronic constipation, suspected of having hirschsprungs disease, who are admitted for rectal biopsy will be included in the study. During the procedure, electrophysiological reading from the site chosen for biopsy will be done. Correlation between electrophysiological data and histopathology will be analyzed.

Study Overview

Status

Unknown

Detailed Description

Hirschsprungs disease is found in 1:5000 newborns, the disease is caused by aganglionosis of the colon, leading to severe constipation and possible bowel obstruction. The diagnosis is based on leveling biopsies taken from the rectum and colon. Treatment is supportive if complications had arisen, and surgical for definitive correction of the pathophysiological condition which is the cause of the disease. Currently, clinicians rely on histopathology, for diagnosing the disease, and planning surgical correction. The main goal of Surgical treatment will be the creation of a continuous patent and innervated bowel, in which effective propulsive peristalsis is taking place. This is achieved by resection of aganglionic colon, and anastomosis of normal colon with normal ganglia, to anus. Today surgeons await histopathology report for the diagnosis of Hirschsprungs disease, and frozen section biopsies taken when in surgery to ascertain the level of ganglionated bowel.

In this study the investigators aim to correlate electrophysiological reading, from colon suspected of Hirschsprungs disease. If correlation is found, or a specific pattern which is diagnostic of the disease may be found, the electrophysiological study may offer a new way of diagnosing the disease, which is not invasive and allows prompt diagnosis in contrast to histopathology which is time consuming. A reliable electrophysiological study for Hirschsprungs disease may be helpful in early and correct diagnosis, with a noninvasive procedure as compared to a biopsy of the colonic wall. Children with chronic constipation, suspected of having hirschsprungs disease, who are admitted for rectal biopsy will be included in the study. During the procedure, electrophysiological reading from the site chosen for biopsy will be done. Correlation between electrophysiological data and histopathology will be analyzed. The actual reading will be carried out by a custom made electrode by GAELTEC DEVICES LTD : DUNVEGAN : ISLE OF SKYE : SCOTLAND.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Child suspected of Hirschsprung disease
Children admitted for biopsy, so that Hirschsprungs desease may be ruled out or diagnosed, whom are planned for rectal biopsy, by clinical decision.
Children admitted for rectal biopsy, due to chronic constipation and suspected of Hirschsprungs disease, will undergo electrophysiological reading from the rectal inner wall, at thechosen site for biopsy before biopsy is performed. Histopathology and readings will be analyzed for corelation
