Large bowel obstruction: an unusual presentation of salmonella enterocolitis in infancy.

An infant with a large-bowel obstruction due to Salmonella B enterocolitis is presented. The clinical and radiologic findings were suggestive of Hirschsprung's disease with total colonic aganglionosis. Due to further deterioration, an ileostomy was performed. Pathologic examination disclosed ganglia in the colon. At laparatomy, 1 month later the colon, which was almost completely obliterated, was resected and an ileorectal anastomosis carried out. The patient remained a carrier of a multiple antibiotic-resistant group B Salmonella strain, and 2 months later died as a result of severe gastroenteritis.
