We report 4 cases of adults patients, suffering from irritable bowel s
yndrome, which had been attributed late to toxocariasis and for whom t
he treatment led to recovery. Hypereosinophilia was present only in 3
cases. These cases show that toxocariasis is not limited anymore to if
s two classical expressions: visceral larva migrans and ocular toxocar
iasis. So it ir;useful to think of if to confirm and treat it in the c
ase of patients suffering from irritable bowel syndrome. This enables
shorter diagnosis delay (14 months in average for our patients) and th
is is essential for therapeutic efficiency.
