[Case of abdominal compartment syndrome (ACS) associated with perforating appendicitis].

A 4-year-old girl with perforating appendicitis developed abdominal compartment syndrome (ACS). Appendicitis in children of preschool age is highly likely to rupture, resulting in serious condition. Although we gave priority to systemic management in this ACS case since the child showed disturbed consciousness due to intracranial hypertension as well as hypercytokinemic encephalopathy. However, we should have performed abdominal decompression by laparotomy early. ACS causes progressive multiple organ failure through compromising the respiratory and circulatory systems and injuring multiple organs, leading to generalized inflammatory reactions. We should, therefore, manage ACS patients systemically sharing a notion that they must be treated early with abdominal decompression by laparotomy.
