It is formed by a fold of peri- toneum, the ileocecal fold (plica ileocecalis), or "bloodless fold" of Treves, the upper border of which is attached to the ileum, opposite its mesenteric attach- ment, while the lower border, passing over the ileocecal junction, joins the mesentery of the appendix, and sometimes the appendix itself; hence this fold is sometimes called the ileoappendicular fold. Between this fold and the mesen- tery of the vermiform appendix is the inferior ileocecal fossa. It is bounded above by the posterior surface of the ileum and the mesentery; in front and below by the ileocecal fold and behind by the upper part of the mesentery of the appendix.

In some cases it is sufficiently large to admit the index finger and extends upward behind the ascending colon in the direction of the kidney; in others it is merely a shallow depression. It is bounded and formed by two folds: one, the external parietocolic fold, or the superior cecal fold, which is attached by one edge to the abdominal wall from the lower border of the kidney to the iliac fossa and by the other to the postero-external aspect of the colon; and the other, the inferior cecal or mesentericoparietal fold, which is in reality the insertion of the
