mesoappendix
Pronunciation: mez-oh-ap-PEN-dix
The mesentery of the vermiform appendix containing blood vessels and requiring division during appendectomy.
Full Definition
The mesoappendix is the triangular fold of peritoneum that connects the appendix to the terminal ileum and cecum, serving as the mesentery for the vermiform appendix. It contains the appendicular artery and vein, which are branches of the ileocolic vessels. During appendectomy, careful division of the mesoappendix is essential to control vascular supply while avoiding injury to nearby structures. The term is fundamental to accurate documentation of appendectomy procedures and anatomical descriptions.
Usage
Usage note: Distinguish from other mesenteric structures when documenting appendectomy.
