Evaluation of intestinal absorption after longitudinal intestinal lengthening for short bowel syndrome.
OBJECTIVE
The aim of this study was to answer if the longitudinal intestinal lengthening and tailoring (LILT) by Bianchi, modified by Aigrain, can allow the child to be weaned from parenteral nutrition (PN) and if the length of the bowel after the procedure can influence the results of the absorption test such as Schilling or D-xylose test.


METHODS
We reviewed the files of 7 children who have had LILT from 1980 to 2003. We performed to explore 2 intestinal function tests: the D-xylose and the Schilling tests. Both were performed early (during the first year after the procedure) and late (during the second year) after the LILT. We used the chi2 and Bartlett's correlation tests for statistical analysis.


RESULTS
There were 6 boys and 1 girl. The surgical indication was short bowel syndrome with parenteral nutrition owing to multiple intestinal atresia (2 cases), severe necrotizing enterocolitis with volvulus (1 case), necrotizing enterocolitis (1 case), intestinal atresia with gastroschisis (2 cases), and volvulus owing to malrotation (1 case). The length of the bowel was significantly different before and after LILT (P < .0001). After LILT, the length of the bowel was significantly correlated with the percentage of PN on energy at 6 months (P = .02) and at 12 months (P = .001). Moreover, the length of the bowel after the procedure was significantly correlated with the results of the D-xylose test during the first year (P = .002) but not with the results after the second year. The length after lengthening influenced neither the results of the Schilling test during the first nor those of the second year after. Four patients were weaned from the PN 21 months in average after the LILT (57%); 1 was not because we had only a 2-month follow-up. The average follow-up was 111 (5 months; range, 4-206).


CONCLUSIONS
Longitudinal intestinal lengthening and tailoring for short bowel syndrome is a good option to allow children to be weaned from the PN. The length of the bowel after the procedure can influence the absorption test such as D-xylose during the first postoperative year but not during the second and does not influence the Schilling test. We think it is not necessary to perform these tests during the follow-up of these patients.
