FACTORS INCREASING INTRA-ABDOMINAL PRESSURE IN PATIENTS WITH A COMPLICATED COURSE OF ACUTE PANCREATITIS

Abstract

Relevance. The frequency of development of intra-abdominal hypertension in patients with a complicated course of acute pancreatitis is 60-70% and leads to an increase in the mortality rate up to 62%. Acute peripancreatic fluid collection, occurring in 65.2-88.9% of patients with moderate and severe acute pancreatitis in the early period of the disease, is one of the causes of increased intra-abdominal pressure.
 Objective: to assess the effect of acute peripancreatic fluid collection on intra-abdominal pressure and the effectiveness of paracentesis with drainage of the abdominal cavity as a method of treatment of intra-abdominal hypertension in patients with complicated course of acute pancreatitis in the early period of the disease.
 Methods. The study included 60 patients with a complicated course of acute pancreatitis, who were divided into two groups depending on the features of the selected treatment tactics: the main group (paracentesis, drainage of the abdominal cavity was additionally performed) – 30 patients, the comparison group (conservative therapy was applied) - 30 patients. Intra-abdominal pressure indicators were compared in the studied groups and performed a comparative analysis of the dependence of its changes on the amount of exudate removed from the abdominal cavity.
 Results. When using paracentesis and drainage of the abdominal cavity in the early period in patients with a complicated course of acute pancreatitis, a significant difference was obtained between the intra-abdominal pressure indicators in the studied groups after one day (8.7±1.5 vs. 14.7±3.3 mm Hg (p<0.0001)) and after 7 days (10.5±1.3 vs. 12.7±2.5 mm Hg (p=0.0001)). In the patients of the main group, a decrease in intra-abdominal pressure was observed on the first day after paracentesis, followed by an increase after three days and stabilization after 6 days, and an average negative correlation was found between the amount of exudate removed from the abdominal cavity and changes in intra-abdominal pressure with the Pearson coefficient r = - 0.4418.
 Conclusions. The use of paracentesis, drainage of the abdominal cavity in patients with complicated course of acute pancreatitis in the early period of the disease can be considered as a safe and effective method of treatment of intra-abdominal hypertension in this category of patients.
