The authors report on a retrospective study 20 cases of intussusception in senegalese children. The diagnosis is essentially clinical. In difficult cases plane abdominal X-rays, barium meal and echography are indispensable exams. In our context the diagnosis is most of the time late and it is due to the unknown nature of the affection and early consultation to the traditional practitionners. The lateness of the diagnosis leads to the lateness of the management. This explains the importance of intestinal necrosis noticed in our serie and the high mortality rate which is 10%. The authors suggest recommendations to ameliorate the prognosis of this ailment which is good elsewhere.
