Brief Summary

Acute pancreatitis is a multi-system disease with an unpredictable clinical course and significant morbidity and mortality Approximately 20% of patients develop multi-organ failure requiring management within a critical care environment However much of the pathophysiology of the disease, particularly understanding why some patients develop life-threatening disease whilst others have a relatively benign course, remains unclear.

It well recognised that intra-abdominal hypertension (IAH) is a cause for organ dysfunction in critically ill patients and is associated with higher morbidity and mortality rates (Sugrue et al., 1999). Abdominal compartment syndrome (defined as an increase in intra-abdominal pressure (IAP) >20mmHg) is associated with new organ failure (Malbrain et al., 2006). The mechanisms believed to contribute to IAH in acute pancreatitis include increased capillary permeability, hypoalbuminaemia and volume overload ("third space losses"), producing retroperitoneal and visceral oedema (Dambrauskas et al., 2009).

Several small studies have recently described the link between intra-abdominal hypertension and adverse outcome in acute pancreatitis ( Dambrauskas et al., 2009; de Waele et al., 2005), however none of the authors appreciate the potential predictive value of there conclusions or the potential as a target for therapeutic intervention to alter the disease course.

This study aims to study the natural history of intra-abdominal pressures in acute pancreatitis and determine whether they truly do have a predictive value or whether they are simply another marker of organ failure in a multi-system disease with notoriously poor outcome.

Detailed Description

Acute pancreatitis is a multi-system disease with an unpredictable clinical course and significant morbidity and mortality (Wilmer, 2004). Approximately 20% of patients develop multi-organ failure requiring management within a critical care environment (Dambrauskas et al., 2009). However much of the pathophysiology of the disease, particularly understanding why some patients develop life-threatening disease whilst others have a relatively benign course, remains unclear.

Many predictive scales have resulted from attempts to predict which patients are likely to develop severe disease (Imrie, Ranson, APACHE-II etc.) (Barreto & Rodriguez, 2007). However none of these scoring systems actually correlate clinical findings with the pathophysiology of the disease process, making comprehension of the rationale for the prognostic value which these scales have been shown to have difficult. This has lead latterly to interest in measurement of intra-abdominal pressures (IAP) as a potential novel method to predict outcome in acute pancreatitis (Buter et al., 2002) since intra-abdominal hypertension can be explained by the disease processes in acute pancreatitis.

It well recognised that intra-abdominal hypertension (IAH) is a cause for organ dysfunction in critically ill patients and is associated with higher morbidity and mortality rates (Sugrue et al., 1999). Abdominal compartment syndrome (defined as an increase in IAP >20mmHg) is associated with new organ failure (Malbrain et al., 2006). The mechanisms believed to contribute to IAH in acute pancreatitis include increased capillary permeability, hypoalbuminaemia and volume overload ("third space losses"), producing retroperitoneal and visceral oedema (Dambrauskas et al., 2009).

Several small studies have recently described the link between intra-abdominal hypertension and adverse outcome in acute pancreatitis ( Dambrauskas et al., 2009; de Waele et al., 2005), however none of the authors appreciate the potential predictive value of there conclusions or the potential as a target for therapeutic intervention to alter the disease course.

This study aims to study the natural history of intra-abdominal pressures in acute pancreatitis and determine whether they truly do have a predictive value or whether they are simply another marker of organ failure in a multi-system disease with notoriously poor outcome.
