[Colonic stenosis following necrotizing enterocolitis in newborn infants. Apropos of 3 cases].

Three cases of double left colic stenosis revealed at one month of age by subobstruction are reported. Recovery was obtained by surgery. The evolution of radiological data in one case, and of histological changes observed on the resected sigmoid colon in the two other cases favor the assumption that cicatricial stenosis occurred likewise. These cases also confirm the existence of a benign expression of necrotising enterocolitis, most common with a colonic localization. Such stenosis due to submucous connective sclerosis strengthens the hypothesis that a transitory mesenteric ischemia is responsible for the necrotizing enterocolitis in newborns.
