Abdominal compartment syndrome and acute pancreatitis.

Significant visceral edema associated with massive fluid resuscitation, paralytic ileus and formation of pancreatic ascites in patients with severe acute pancreatitis (SAP) can lead to abdominal compartment syndrome (ACS) that can contribute to the early development of multiple organ dysfunction syndrome (MODS), especially in the early stages of the disease. The prevalence of intra-abdominal hypertension (IAH) in SAP is about 40% and a manifest ACS occurs in about 10% of the patients warranting close monitoring of intra-abdominal pressure (lAP) in all patients with the severe form of the disease. Although nonsurgical management utilizing percutaneous drainage of ascites or continuous hemodiafiltration may decrease IAP, most patients require decompressive laparostomy and temporary abdominal closure. The primary aim in managing the ensuing open abdomen is delayed fascial closure during initial hospitalization. On many occasions a planned hernia approach, either with early skin grafting over the exposed bowel or managing the ASC primarily with a subcutaneous linea alba fasciotomy, is the only available option. The development of ACS in patients with SAP seems to be associated with increased mortality.
