Figure 22.12 Mechanical ileus in an 11-year-old domestic longhair with a history of vomiting. Obstruction was secondary to marked
thickening of the jejunal wall likely caused by lymphoma. Euthanasia was performed without necropsy. (a) In the left lateral
recumbent projection, gas can be seen in the pylorus (P) and the duodenum (D) is distended with gas. (b) On the right lateral
projection, gas is now seen in the fundus (F), body of the stomach, and duodenum (D). (c) Ventrodorsal projection. (d) An ultrasound
scan shows fluid in the distended stomach. The gastric wall measured 0.42 cm between the calipers. (e) The jejunum was distended
proximal to the obstruction. Fluid could be seen moving to and fro without progressing through the intestine. (f) The duodenum was
distended with fluid. Calipers are placed to measure the adjacent pancreas.
