Histochemical diagnosis of Hirschsprung's disease and a comparison of the histochemical and biochemical activity of acetylcholinesterase in rectal mucosal biopsies.

چکیده
Three hundred and seventy-two rectal mucosal biopsies, taken from 150 children and young adults with chronic constipation, were subjected to histochemical and biochemical analysis of acetylcholinesterase to excude Hirschsprung's disease. The relative merits of the procedures were compared. The histochemical method was considered to be the most practical for laboratories handling small numbers of biopsies but the biochemical estimation of acetylcholinesterase activity was found to be a useful complementary procedure and an accurate quantitative assessment of enzyme activity.

متن کاملClinical evaluation of the histochemical diagnosis of Hirschsprung's disease.
The histochemical staining of suction rectal biopsies for acetylcholinesterase (AChE) activity is a safe and accurate diagnostic tool in the management of patients with symptoms and signs of Hirschsprung's disease. In this study 101 patients who have undergone AChE analysis of suction rectal biopsies are presented in order to correlate histochemical findings with subsequent clinical course afte...
متن کاملExperience with a cholinesterase histochemical technique for rectal suction biopsies in the diagnosis of Hirschsprung's disease.
Cryostat sections from 160 rectal suction biopsies were stained for cholinesterases by the method of Karnovsky and Roots (1964) in an attempt to facilitate the diagnosis of Hirschsprung's disease. The method proved at least as reliable as experienced assessment of paraffin haematoxylin-eosin sections, and appeared to offer the advantages of reduced scanning fatigue and superior demonstration of...
متن کاملAcetylcholinesterase histochemistry of rectal suction biopsies in the diagnosis of Hirschsprung's disease.
Rectal suction biopsy with acetylcholinesterase (AChE) histochemistry has gained increased acceptance as the means of definitely diagnosing Hirschsprung's disease (HD) as well as of excluding this diagnosis when evaluating children with low intestinal obstruction or chronic constipation since the report of Meier-Ruge et al. in 1972. But this AChE histochemical study has not been reported yet in...

Background and purpose: Hirschsprung’s disease (HD) is the most common etiology of neonatal intestinal obstruction. Definite diagnosis is based on demonstration of aganglionosis in seromuscular and full tickness rectal biopsy. Because of problems and complications of full tickness and seromuscular rectal biopsies, mucosal-submucosal rectal biopsy is prefered,but interpretation of these biopsi...
