An excellent classification for boundaries of hernias was formulated by Meyer, 4 5 who described six boundaries: paracecal sulci, cecal fossa, cecal recess, superior ileocecal recess, inferior ileocecal recess, and retrocecal recess. Paracecal sulci are lateral depressions of the peritoneum invested on the cecum, but recesses may be absent.
A retrocecal recess is formed by the cecum anteriorly, the iliac fossa posteriorly, the right colic gutter laterally and the mesentery medially.
