Abstract

OBJECTIVE:

The aim of this study was to determine the diagnostic value of push enteroscopy in patients with chronic diarrhea and malabsorption of unclear origin.

METHODS:

From January, 1997, to September, 1999, 16 consecutive patients with chronic diarrhea and biological signs of intestinal malabsorption but no evidence of celiac disease were explored by push enteroscopy. Previous duodenal histological findings had been normal in seven patients and abnormal but inconclusive in nine patients. Endoscopic and histological findings in the duodenum and in the jejunum were compared.

RESULTS:

Push enteroscopy with jejunal biopsy yielded a diagnosis in comparison with duodenal biopsy in two of 16 (12%) patients, respectively, in two of the nine (22%) patients with abnormal but inconclusive findings on duodenal biopsy, and none of the seven patients with normal duodenal histology. In the two patients in whom jejunal biopsy had diagnostic value but duodenal biopsy did not, the final diagnoses were invasive intestinal lymphoma and microsporidiosis.

CONCLUSION:

Push enteroscopy had diagnostic value in only 12% of patients with malabsorption of unclear origin, all of whom had had abnormal but inconclusive duodenal histological findings. Push enteroscopy with jejunal biopsy appears to have limited diagnostic value in patients with chronic diarrhea and malabsorption, especially when duodenal biopsies are histologically normal.
