Morphologic pattern of myenteric neural plexus in colonic diverticular disease. A whole-mount study employing histochemical staining for acetylcholinesterase

The occurrence of DD in sigmoid colon is associated with morphologic alterations in MNP (i.e. the number of ganglia and plexus rarefaction, ganglion size and plexal area involution), which presumably demonstrate the failure of MNP in DD patients.
