The relationship between the level of thirteen different substances and enzymes in blood and peritoneal fluid and the duration of mechanical intestinal obstruction: an experimental study on rats.

Our data suggest that peritoneal fluid and blood ammonia levels and blood aldolase levels rise according to duration of the intestinal obstruction. Since the results were not available to determine cut-off levels, future research is required to confirm these results and determine whether ammonia or aldolase can be used in clinical practice to predict the presence and duration of a mechanical intestinal obstruction.
