AXR AP (left) shows the cecostomy tube lying medial in position to the cecum. AP image during injection of water soluble contrast through the cecostomy tube (above right) shows opacification of the retroperitoneum rather than the cecum. After the cecostomy tube was removed and replaced, an AP image during injection of water soluble contrast through the new cecostomy tube (below right) shows opacification of the cecum.
