Abstract
In a 6-yr period, lesions were identified by enteroclysis in 26 patients with melena or recurrent gastrointestinal bleeding undiagnosed by other modalities. These included 9 Meckel''s diveticula, 3 metastatic lesions, 3 primary carcinomas, 1 lipoma, 4 leiomyomas, 5 surgically created blind pouches, 1 carcinoid, and 1 idiopathic dilatation of the ileum. When the standard diagnostic procedures used to investigate chronic gastrointestinal blood loss are unrevealing, enteroclysis should be performed. The method is fast, accurate, is done in 1 sitting, and can be productive in the diagnostically difficult patient.
