title: [Abdominal compartment syndrome].
abstract: Abdominal compartment syndrome (ACS) is defined by the deleterious effects of intraabdominal hypertension (IAH) on the pulmonary, cardiovascular, splanchnic, urinary and central nervous system. Abnormal and sudden increase in the volume of any component of the intraperitoneal or retroperitoneal space (occurRing postoperatively or subsequent to hemorrhagic trauma, referfusion edema, penumoperitoneum, intestinal distention, acute pancreatitis...) causes IAH. Sustained IAH leads to ACS which if left unrecognized or untreated is always fatal. Measurement of urinary bladder pressure is the best validated technique for diagnosis of IAH. It should be used routinely for minimally invasive surveillance of intra-abdominal pressure (IAP) in patients with severe thoraco-abdominal trauma or after major abdominal operations. Medical management of IAH is of limited efficacy making expedient surgical decompression the treatment of choice for ACS. Surgical decompression of the abdomen and temporary closure is generally recognized as effective in clinically patent ACS but the pressure threshold indicating the need for decompression remains controversial. No data are available from controlled randomized trials and current guidelines are based on the experience of large trauma centers. The few available prospective clinical series report survival rates in the 38 to 71% range after surgical decompression for ACS. These studies are difficult to compare due to methodological features but it would appear that centers using the lowest pressure threshold for decompensation (< 20 mmHg) have the highest survival rates. Despite the available physiological arguments, indications for prophylactic temporary abdominal coverage (TAC), e.g. in trauma patients or for early decompression in IAH patients without clinical ACS, have not been validated in clinical practice. The potential morbidity of decompression procedures, TAC, and subsequent abdominal wall reconstructions require comparative studies of these treatment options with available pharmacological and non-surgical means to lower IAP.
