[Toxocariasis and functional intestinal disorders. Presentation of 4 cases].

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