Malabsorption secondary to Meckel's diverticulum.

This case report of a patient with a large Meckel's diverticulum with associated stagnation and bacterial proliferation demonstrates the resultant metabolic and nutritional alterations that have classically been described with the blind loop syndrome. A lesion as large as the one presented herein has rarely been reported with iron, vitamin B12, and folic acid deficiency anemias secondary to the contaminated small bowel (ileum) syndrome. A discussion of the pathophysiology, diagnosis, and treatment of this disorder and the multiple disease entities incorporated in the contaminated small bowel syndrome are included.
