Releif of severe fecal impactions with water-soluble contrast enemas.

High fecal impaction resulted in complete bowel obstruction in 2 children following renal transplantation and in one adult on chemotherapy and narcotics. The usual methods of relief failed, and water-soluble contrast enemas with a high osmolality were employed. Fluoroscopic control assured placement of the enema fluid at the site of obstruction, where it was very effective in relieving the impaction. It is suggested that such high-osmolality enemas be considered in patients with severe high fecal impactions before surgery is contemplated.
