Cheatle slit

Chea·tle slit

(chē'tĕl),
a longitudinal incision into the antimesenteric border of the small intestine, which, when closed transversely, creates a larger lumen than would be possible by simple end-to-end anastomosis; currently modified to include longitudinal incisions into the cut ends of the transected small intestine or other tubular structures, allowing a wide caliber elliptic anastomosis to be performed.
