Ascariasis is the largest and most prevalent human helminthes. It’is more frequent in underdeveloped countries because of poor hygiene and low socio economic conditions. Ascaris can lead to hepatic, pancreatic and intestinal complications. Intestinal obstruction is more frequent in children. We report two cases of ascariasis infestation presented with bowel obstruction. Both patients were from rural area. Because of the volvulus with necrosis of ileal loop, the first patient underwent an intestinal resection with end to end anastomosis. The second patient was diagnosed first as an appendicular peritonitis; it’s during surgery that we discover the presence of an intestinal blockage with parasite. His management was more conservative: jejunum enterotomy was performed and the worms were removed. Both patients receive albendazole in the post operative course, with satisfaisant clinical evolution. Pediatrician should be aware of the abdominal complications; an early recognition of this condition can prevent serious complications, morbidity and mortality.
