[Abdominal compartment syndrome: significance, diagnosis and treatment].

A pathological increase of intraabdominal pressure (IAP) is frequently observed in severely ill patients suffering from surgical diseases. This may lead to the abdominal compartment syndrome (ACS) which is characterized by an IAP >20 mmHg (>2.67 kPa) and failure of one or more organ systems. The mortality of ACS exceeds 60%. Knowledge concerning the sequelae of ACS is abundant, however, measurement of IAP is not routinely performed even if patients present with corresponding risk factors. This is probably due to a variable incidence of ACS and scepticism regarding the results of bladder pressure measurement. However, measurement of IAP can now be performed semi-automatically, continuously and in a standardized fashion. The therapy of ACS, i.e. decompression laparotomy and laparostomy, is undisputed. Since a heterogeneous group of patients can be affected, monitoring of IAP is indicated in patients needing intensive care. A consistent registration of IAP will improve knowledge and guidelines regarding the therapy of a pathologically increased IAP. Nevertheless, patients in whom ACS is suspected should be decompressed as soon as possible.
