The authors propose to confer on the Ogilvie's syndrome the same impor
tance that the sudden death or the malignant syndrome have, with regar
d to the complications of schizophrenia and of neuroleptic drugs. Lite
rature, medical teaching and research are concerned. This functionnal
occlusion can be letal through an intestinal necrosis, with or without
a surgical intervention - a total colectomy being the therapeutic rul
e. The anticholinergic effects of neuroleptics are incriminated, but o
ther non-psychotropic drugs as well as non-anticholinergic drugs can b
e involved Preventive measures based upon pharmacoepidemiologic survey
s or on neuroleptic monotherapy remain hazardous. All the intervenants
in the field could benefit from both formation and information. The c
linical and radiological emergence of an intestinal dilatation is the
only alarming sign that is constant and relevant. Three cases are reca
lled and three others are described here.
