Demonstration of the increasing activity of acetylcholinesterase (AChE) in a segment
of the colon has proved to be the most accurate diagnostic tool to diagnose Hirschsprung เธ— s
disease. Two methods of histochemical assessment were tried to establish the most appropriate
and effective method for this study within the limitation of available equipment. Lakeเธ— s method
was chosen and was modified as the standard histochemical examination.
