Mesentery is a double fold of peritoneum that suspends the small intestine from the posterior abdominal wall, relevant in simulation for bowel handling and mesenteric dissection training. The mesosalpinx is a separate fold of peritoneum: it is the upper margin of the broad ligament, it encloses the fallopian tube, and it carries the tubal blood supply and lymphatic vessels. It is also called the mesentery of the fallopian tube.

Materials

Material	Visual	Tactile	Simulator	Notes
Flat Bed Sheet			Meckel's Diverticulectomy Simulator	Unrolled portion of the same bed sheet; the bunched end forms the mesentery root attachment to the bowel.
Cotton Stuffing			Acute Appendicitis Simulator	Cotton or gauze in plastic wrap forms the mesoappendix carrying the appendiceal artery.
Cloth, Knitted	-	-	Appendectomy Simulator
Surgical mask (scrub-cap material) + yarn			Open Appendectomy Simulator (Matthews)	Scrub-cap material folded around a length of red yarn forms the mesoappendix that carries the appendiceal artery.^[1]
Castable silicone			Laparoscopic Appendectomy Simulator (Roche)	Roche: Ecoflex 00-10 (Shore 00-10) forms the mesoappendix. The component is single-use and is replaced together with the appendix.^[2]
