jejunojejunostomy

His landmark 1963 guide to medical terminology, for instance, teaches reporters how, by understanding prefixes, suffixes and roots, they can differentiate between a colotomy, a colostomy, and a colectomy and handle an occasional jejunojejunostomy as well.

The mesenteric defect in such cases, called Petersen's defect, is located between the transverse colon and the mesentery of the alimentary limb (the segment of the jejunum from the jejunojejunostomy until the connection with the proximal segment of the stomach) at the level of the jejunojejunostomy.
