Appendicectomy stumps: 'to bury or not to bury'.

A prospective randomized trial of 130 patients was carried out to compare simple ligature with invagination of the appendix stump. There were 64 and 66 patients, respectively, in the two groups and they were well matched for age, sex, weight and severity of appendicitis. One patient in the invagination group developed wound infection but there was no infection in the other group. This difference was not statistically significant (P greater than 0.5) and there was no evidence of adhesive ileus in either group after a mean follow-up period of nine months. We recommend simple ligature of the appendix stump as a safe procedure.
