The Alteration Of Intestinal Flora In Patients With Reconstruction Of The Upper Gastrointestion Tract

Objective To investigate changes in species and amounts of intestinal flora after reconstruction of upper digestive tract,and the relationship with the infective complications.Methods Forty-five patients with advanced malignancy being performed reconstruction of upper gastrointestinal tract was prospectively observed.The species of bacteria and counts of the colony forming units(CFU) were measured from juice taking from the upper jejunum through nasointestinal tube during operation,the second day and the fifth day after operation.Results There weren't significant changes of intestinal flora in species and amounts between groups(p> 0.05.) No any signs of bacterial translocation were seen.Conclusion The data suggest that there are no disorder of intestinal flora and bacterial translocation during the perioperative period after upper digestive tract reconstruction successfully.
