During an appendectomy (
http://wiki.medpedia.com/Appendectomy ) it was once the standard to perform invagination of the appendiceal stump into the cecum. The advent of surgical stapler use rather than suture ligature of the appendix decreased the rate of inversion, and the change from the traditional open appendectomy to the laparoscopic procedure performed more commonly today has decreased this even more. The open procedure is still performed, however, and it is not uncommon for a surgeon to invert the stump during an open appy. Several articles (
