Explicative variables of stool weight, protein absorption, and fat absorption according to multivariate analysis in 90 adult short bowel patients
| Stool weight | Fat absorption | Protein absorption | |
|---|---|---|---|
| *p = 0.08. | |||
| The predictive equations for the three variables are: | |||
| stool weight (g/day) = 2989 + 9.63 × simple carbohydrate intake (g/day) − 12.51 × jejunum length (cm) − 14.31 × ileum length (cm) − 18.75×colon (% in continuity); | |||
| net fat digestive absorption (%) = 52.2 + 0.139 × jejunum length (cm) + 0.248 × ileum length (cm) + 11.35 × ileocaecal valve (yes or no) − 0.142 × fat intake (g/day); | |||
| net protein digestive absorption (%) = 46.5 + 0.153 × jejunum length (cm) + 0.286 × ileum length (cm). | |||
| Jejunum length | p<0.001 | p<0.01 | p = 0.001 |
| Ileum length | p<0.05 | p<0.05 | p<0.01 |
| Radiographic abnormal pattern of remnant small bowel | NS | NS | NS |
| Presence of ileocaecal valve | NS | NS* | NS |
| Per cent of colon in continuity | p<0.001 | NS | NS |
| Simple carbohydrate intake | p<0.001 | ||
| Protein intake | NS | NS | |
| Fat intake | NS | p<0.05 | |
