The increase in diet VR after the 2nd week of EN in
control group patients was an unexpected finding. We
have no clear explanation for this. Nevertheless, the
importance of this finding would be anecdotal if we
consider that a great number of our patients receive EN
in the first 2 weeks and that this period is also when
EN-related GI complications preferentially occur. Other
authors [7, 27] have also pointed out that the increase in
gastric residuals is appreciated mainly during the 1st days
of EN, a period in which the impairment in gastric
motility also occurs preferentially.
