We have carefully analyzed the causes of recurrence in our 1,211 hernioplasties performed over a 22-year period. In addition to recording our overall recurrence rate, we have divided the hernias into four categories based upon the pathologic anatomy and then studied the causes of recurrence for each group. We have suggested a formula for the uniform reporting of more short-term follow-up studies so that more meaningful data will be available to surgeons in the future. Our overall recurrence rate is now 3.5%, but projects to 4.2% at the end of 25 years.
