To assess the frequency of and risk factors for intolerance to enteral nutrition through nasogastric (NG) or nasojejunal (NJ) tube feeding in patients with moderately severe acute pancreatitis.

Patients and Methods:

Patients who underwent enteral nutrition via the nasojejunal tube or nasogastric tube, from January 2012 to December 2017, were enrolled. Demographic and etiological data, admission variables, enteral nutrition related variables, and radiological variables were evaluated using univariate and multivariate analysis.


A total of 568 patients were included, with 235 (41.4%) receiving nasojejunal tube feeding and 333 (56.8%) receiving nasogastric tube feeding. Tube-feeding intolerance was observed in 184 patients (32.4%), occurring at a median of 3 days (range, 1-5 days) after the start of enteral nutrition. The variables independently associated with risk of intolerance to tube feeding were hypertriglyceridemia (odds ratio, 8.13;95% CI, 5.21-10.07; P = 0.002), the presence of systemic inflammatory response syndrome (odds ratio, 6.58;95% CI, 3.03-8.34; P = 0.002), acute gastrointestinal injury-III status (odds ratio, 5.51;95% CI, 2.30-7.33; P = 0.02), the time from admission to commencement of enteral nutrition (odds ratio, 7.21;95% CI, 2.16-9.77; P = 0.001), and pancreatic infection (odds ratio, 6.15;95% CI, 4.94-8.75; P = 0.002) Patients with tube-feeding intolerance required prolonged enteral nutrition (P < 0.001) and had longer hospitalizations (P < 0.001).


Tube-feeding intolerance accounts for a considerable proportion in patients with moderately severe acute pancreatitis. The presence of hypertriglyceridemia, systemic inflammatory response syndrome and acute gastrointestinal injury grade III or pancreatic infection and the time from admission to commencing enteral nutrition increase the risk for tube-feeding intolerance.
