Gastric gland metaplasia after jejunoileal by-pass surgery for morbid obesity.
A 56-year female is described who developed recurrent oxalate nephrolithiasis six years following jejunoileal by-pass surgery for morbid obesity. Subsequently a revision of the jejunoileal by-pass was performed when it was recognized that the site of the anastomosis showed segmental dilatation proximal to the anastomosis. A unique microscopic finding was true gastric gland metaplasia consisting of parietal cells and mucus neck cells in the ileal mucosa of the resected specimen.
