Two terms should be defined at the outset. The first is "nonspecific," by which is meant "of unknown or undetermined origin." The second is "right portion of the colon," by which is meant "the cecum, ascending colon and hepatic flexure."

This study of surgical resection for nonspecific ileocolitis was prompted by a recent review of malignant lesions of the right portion of the colon. The present review is based on the records of 100 patients for whom the terminal portion of the ileum and the right portion of the colon were resected for nonspecific inflammatory disease. Resection in these 100 cases was performed by eleven different surgeons.

In an attempt to evaluate the results of possible surgical procedures, the cases were classified into the divisions of "stage operation" suggested by Lovelace and one of us (Mayo). This has been modified as in table 1.
