We conducted a retrospective and prospective study and collected 35 cases of ADR, including 21 boys and 14 girls, over a period of 4 years from January 2017 to December 2020. We counted an average of 8.7 cases of ADR per year, more frequent in boys with a sex ratio of 1.5. The majority of our patients were from the Mopti region and were of Dogon ethnicity. Most of the malformations were discovered by the parents since 54.3% of the mothers had given birth in a health center and the malformed children were most often seen in a state of intestinal obstruction or sub-occlusion requiring an emergency colostomy. The diagnosis was made during the systematic examination of the newborn in the delivery room in 8.57% of our patients. 48.6% of our patients had a low form of malformation. 15 patients (42.9%) had an invertogram. The anomalies associated with MAR were dominated by spinal malformations in 4 cases (11.4%).
