An alternative approach to pyogenic hepatic abscess in childhood.

ABSTRACT

Childhood pyogenic hepatic abscess is rare and remains a difficult diagnostic problem. Seven cases in six children were treated over a 13 year period. There was a recurrence in one patient 7 years after the first presentation. Four patients had identified predisposing factors, namely, chronic granulomatous disease, acute appendicitis, previous abdominal surgery and umbilical vein catheterization, while the other two were cryptogenic. There were no specific symptoms and signs but the combination of unexplained pyrexia, upper abdominal tenderness, hepatomegaly and leucocytosis should raise the suspicion of hepatic abscess. Four cases were diagnosed by ultrasound, one by radionuclide scan and the other two at laparotomy. Treatment in the earlier years was by transabdominal drainage. In the later part of the series, percutaneous catheter drainage using ultrasound guidance was achieved with satisfactory result. Ultrasonography can provide an early diagnosis and effective treatment can be achieved with percutaneous catheter drainage in combination with appropriate antibiotic therapy.
