Early intra-abdominal hypertension: A reliable bedside prognostic marker for severe acute pancreatitis

Background and Aim: Severe acute pancreatitis (SAP) is commonly associated with intra-abdominal hypertension (IAH). This acute increase of intra-abdominal pressure (IAP) may be attributed to early organ dysfunction, leading to an increased morbidity and mortality. To assess the incidence of raised IAH and its correlation with other prognostic indicators and various outcomes in SAP. Methods and Results: This was a prospective observational study in patients of SAP between July 2009 and December 2010. All patients of SAP who were admitted to the hospital within 2 weeks of onset of pain were included in the study. A total of 35 patients with SAP were included in the study. Among these, 25 (71.4%) were males. All our patients had raised IAP; however, IAH was present in 51.4% (18/35). Patients with IAH were found to have a higher APACHE II score (88.9vs5.9%;P < 0.001), infectious complications (72.2vs5.9%;P < 0.001), circulatory failure (88.9vs0%;P < 0.001), and respiratory failure (100vs41.2%;P < 0.001). All the eight (22.8%) patients who succumbed to sepsis had IAH. Patients with IAH were found to have a significantly longer intensive care unit (ICU) stay (17.72vs12.29 days) and in-hospital stay (24.89vs12.29 days). Conclusion: IAH is a good negative prognostic marker in SAP, seen in up to 51.4%. IAH was found to have a significant negative impact on the outcome in terms of increased mortality, morbidity, in-hospital stay, and ICU stay among the patients of SAP.
