[Endogenous steatorrhea during total parenteral nutrition. Study of 22 patients with gastrointestinal diseases].

Abstract

Endogenous steatorrhea has only been evaluated in patients with non-pathological digestive tract. We decided, therefore, to study this parameter in 22 consecutive patients submitted to total parenteral nutrition for severe gastrointestinal diseases. The determination of steatorrhea, creatorrhea, and fecal clearance of alpha 1-antitrypsin was performed by three days stool collections. After 10 days of parenteral nutrition, 13 of the 22 patients still had measurable stool losses and 106 fecal collections were done. In these 13 patients, fecal weight was 610 +/- 130 g.d-1, (mean +/- SEM), steatorrhea was: 3.1 +/- 0.4 g.d-1, creatorrhea was: 1.7 +/- 0.6 g.d-1, alpha 1-antitrypsin clearance was: 58 +/- 13 ml.d-1 (N less than 10 ml.d-1). The mean endogenous steatorrhea was therefore 5 fold larger than normal and creatorrhea 1.8 fold larger than normal. This discrepancy could be due to metabolism of nutrients by colonic bacterial flora. The comparison of patients with and without increased endogenous losses showed significant differences in the mean number of intestinal lesions (1.4 +/- 0.3 versus 0.5 +/- 0.2) and in the presence or absence of ileal involvement (p less than 0.05). A positive correlation was found between steatorrhea and stool weight but not between steatorrhea and creatorrhea or fecal clearance of alpha 1-antitrypsin. This first study of pathological endogenous steatorrhea does not suggest a relationship of this parameter with protein losing enteropathy. The main contribution to increased endogenous losses may be related to increased epithelial cell renewal of the intestine associated with malabsorption. The role of bacterial overgrowth in the gut cannot be ruled out by the present data.
