Intolerance to Early Nasogastric and Nasojejunal Enteral Nutrition in Patients with Moderately Severe Acute Pancreatitis

RELEVANCE Early enteral nutrition is an essential element of intensive care for acute pancreatitis. Its intolerance is manifested by high gastric residual volumes, pain syndrome, bloating, diarrhea, nausea and vomiting. The relevance of our study is determined by the lack of information on how the routes of nutrient delivery affect its tolerability considering the gradual «as­per­protocol» increase in nutrition volumes for patients with moderately severe acute pancreatitis.THE AIM OF THE STUDY Was to identify the key factors that determine intolerance to early nasogastric and nasojejunal enteral feeding in ICU patients with the early phase of moderately severe acute pancreatitis.MATERIAL AND METHODS We conducted an open randomized controlled trial. Out of 64 patients with predicted severe course of acute pancreatitis, we identified a cohort with moderately severe acute pancreatitis, in which 17 (51.5%) patients received early enteral nutrition through a nasogastric tube, and 16 (48.5%) via an endoscopically placed nasojejunal tube. The criteria for nutrition intolerance were as follows: nasogastric tube discharge of more than 500±100 ml at a time or more than 500 ml/day in comparison with the enterally administered during this period, increased pain, bloating, diarrhea, nausea and vomiting. Using the method of logistic regression, indicators with prognostic significance were determined. The null hypothesis was rejected at p
