Surgical complications of the haemolytic uraemic syndrome

During the first outbreak of haemolytic uraemic syndrome (HUS) to be reported in Australia, 22 children were admitted to the Women's and Children's Hospital, Adelaide. The outbreak was caused by an entero-haemorrhagic Escherichia coli strain (EHEC) of serotype 011:H-, a strain rarely implicated as a cause for HUS. In all 22 patients, the onset of HUS was preceded by a gastrointestinal (GI) prodrome. All patients had diarrhoea. In 17 (73%), the diarrhoea became bloody; in 20 (86%) there was vomiting; in 15 (65%) there was abdominal pain; and in 12 (50%) all three symptoms were present. Abdominal symptoms continued to complicate the course of 4 patients. Two of these underwent exploratory laparotomy, both had gangrenous colon excised, and both survived. The 2 remaining patients were successfully treated non-operatively. One further patient underwent appendicectomy before the diagnosis of HUS was made. There was 1 death during this epidemic. In patients with HUS and GI involvement, optimal surgical management requires careful consideration of the indications for, and the timing of, surgical intervention.V. V. Varjavandi, W. D. A.

Segmental omental infarction in childhood: a typical case diagnosed by CT allowing successful conservative treatment

Segmental omental infarction (SOI) is an uncommon cause of right lower quadrant pain in children that is often misdiagnosed as appendicitis. During the last decade, imaging findings of SOI have proved to be sufficiently typical to avoid unnecessary surgery in the majority of reported adult patients. The condition has a spontaneous favourable evolution under medical treatment. In children the surgical option remains controversial. We report a typical case of SOI in a 10-year-old boy. The diagnosis was suspected by sonography, unambiguously confirmed by multidetector CT and successfully treated conservatively. This report emphasizes the use of CT in selected acute abdominal situations, peculiarly in obese children, to avoid unnecessary surgery
