Multiple enteroliths in a chronically obstructed duodenal loop after Roux-en-Y biliary diversion.

A case of chronic mechanical obstruction of the duodenal loop due to stricturing of the enteroenterostomy after diversion following a Polya gastrectomy for bile reflux gastritis is reported. The dilated loop contained several hundred enteroliths. The clinical and chemical evidence strongly supports the view that the enteroliths were formed in the intestinal loop. This complication of Roux-en-Y reconstruction has not previously been recognized.
