There are two main functions of gastrointestinal tract,digestion and absorption,and barrier function.The latterhas an important defensive effect,which keeps the bodyaway from the invading and damaging of bacteria andendotoxin.It maintains the systemic homeostasis.Intestinaldysfunction would happen when body suffers from diseasesor harmful stimulations.The lesser dysfunction of GI tractmanifests only disorder of digestion and absorption,whereas the more serious intestinal disorders would harmthe intestinal protective mechanism,or intestinal barrierfunction,and bacterial/endotoxin translocation,of intestinalfailure (IF) would ensue.This review disscussed the theoryof the intestinal failure,aiming at attracting recognitionand valuable comments by clinicians.
There are two main functions of gastrointestinal tract, digestion and absorption, and barrier function. Latterly an important defensive effect, which keeps the bodyaway from the invading and damaging of bacteria andendotoxin. It maintains the systemic homeostasis. Intestinaldysfunction would happen when body suffers from diseasesor harmful stimulations. The lesser dysfunction of GI tractmanifests only disorder of digestion and absorption, but the more serious intestinal disorders would harm the intestinal protective mechanism, or intestinal barrier function, and bacterial / endotoxin translocation, of intestinalfailure (IF) would ensue. This review disscussed the theory of the intestinal failure, aiming at attracting recognition and valuable comments by clinicians.
