Surgical image (above left) shows a massively dilated transverse colon (held between the fingers) and massively dilated small bowel to the left of the image. Examination of the splenic flexure of the colon (above right) reveals a transition zone between the transverse colon and descending colon (center of image). Further dissection near the transition zone shows a tight stricture at the transition zone (below in the center of the image).
