This patient has no evidence of dilatation. There is stool in several parts of the colon. If you look closely in the right lower quadrant, there is a fine ring of dense material that represents a GI suture line. This patient has had a resection of the cecum and terminal ileum.

Sutures used for GI anastomoses are very fine metallic staples that are laid down by a stapler, and appear as a fine dense chaine on radiographs. Note the differenct appearance of stool in the more proximal colon, which has a more speckled appearance, compared to stool in the distal colon,which has a more solid, mass-like appearance. Note that the folds in the stomach are longitudinal, which is different from folds elsewhere in the GI tract. These longitudinal folds are called rugae.
