Indications for laparotomy in infection with verotoxigenic Escherichia coli.

Verotoxigenic types of Escherichia coli have emerged as serious and important human pathogens. The clinical disease most frequently manifests as a painful form of bloody diarrhea, which can progress to life-threatening systemic microangiopathic hemolytic anemia, known as the hemolytic-uremic syndrome (HUS). Three children with hemorrhagic enteritis due to verotoxigenic E. coli are presented to illustrate the unique diagnostic, therapeutic, and operative management dilemmas associated with this disease. When contemplating surgery, one should seek to determine the anatomic and transmural extent of the disease.
