title: Preliminary results of a prospective randomized study of Cooper's ligament versus Shouldice herniorrhaphy technique.
abstract: Surgeons have developed many methods for the repair of direct inguinal hernias. The Cooper's ligament (McVay) repair and the Shouldice repair are widely used techniques. To determine the recurrence rates with differing techniques performed in a surgery residency program, we conducted a prospective randomized study for elective adult direct inguinal herniorrhaphies. Three hundred and eight elective direct inguinal herniorrhaphies in 269 adult patients were performed by residents in general surgery supervised by staff surgeons. Patients had yearly follow-up physical examinations (compliance rate of 87 percent) during an average follow-up period of 36.4 months. The recurrence rate was 8.8 percent for the McVay repair and 6.6 percent for the Shouldice repair (not significant). Bilateral inguinal hernias (repaired six weeks apart) had a recurrence rate of 12.8 percent, while the recurrence rate for unilateral repairs was 5.6 percent (p = <0.05). We found no significant difference in recurrence rates between the McVay and Shouldice herniorrhaphy techniques. However, there was an increase in hernia recurrence with either technique when bilateral direct inguinal herniorrhaphies were performed.
