Time-course evaluation of intestinal structural disorders in a porcine model of intra-abdominal hypertension by mechanical intestinal obstruction

Fig 2

Mechanical intestinal obstruction with competent ileocaecal valve in humans (A-C) and a porcine model (D-F). (A) Nondistended colon (no stenosing rectal tumor). (B) Distended colon moderately with competent ileocaecal valve (red circle) and stenosing rectal tumor. (C) Colon with great distention with competent ileocaecal valve (red circle) and stenosing rectal tumor. (D) Anatomical representation of colon in a porcine model. (E) Distal ileum section (red circle) and transrectal catheterization with Foley catheter for perfusion of solution. (F) Distended colon in a “closed loop” colonic obstruction model by increased intraluminal perfusion.
