a, b Longitudinal section through the well healed duodenal-ileal anastomotic site. Note the apposition of all intestinal layers. The duodenal mucosa is contiguous with the ileal mucosa. Fibrous connective tissue (blue in trichrome stain) separates the muscle layers of the two portions of the intestine. The serosa appears slightly edematous. The lymphatics in the ileal submucosa appear dilated. There is no evidence of infection, inflammation or dehiscence at the anastomotic site. a H & E stain; b Masson’s trichrome stain.
