Evaluation of the absorptive area and capacity of short bowel patients using Dxylose absorption test / 肠外与肠内营养

ABSTRACT

O bjectiveTo investigate the effectiveness of D-xylose absorption test in evaluating the ab-sorptive capacity of the remnant small bowel in short bowel patients.M ethods5 hr urine D-xylose ex-cretion,1hr,2hr,3hr serum D-xylose levels and AUC was compared between the short bowel patients(n=22) and the healthy control(n=50).The correlationship among the D-xylose absorptive capacity,the remnant small bowel length and area,and protein absorptive capacity were analyzed.For the 6 pa-tients receiving rehabilitative therapy,theirD-xylose and protein absorption capacities before and after the therapy were also stud ied.R esu lts5hr urine D-xylose excretion,1hr,2hr,3hr serum D-xylose levels and AUC were all significantly lower in short bowel patients compared to control group(P
