Abstract

There are few objective studies in the surgical literature on the strength of an inguinal hernia repair during the immediate postoperative period. To provide the relevant advice and recommendations on physical activities during the period of convalescence, a study on the strength of the Shouldice repair was carried out. Twenty-eight Shouldice repairs were performed on 17 fresh human cadavers (11 male, 17 female, mean age 79.9±6.2 years). Following the excision of the transversalis fascia, the breaking strength and tissue elasticity were measured using an automated test device. All tissue ruptures occurred outside the limits of the Shouldice repair. Mean breaking strength was 53.9±20.1 N, showing no significant differences between males and females. The measured overall elasticity of tissue samples was 4.6±2.3 N/cm. Again there was no marked difference between genders. However, breaking strength and elasticity were found to be significantly affected by age. The Shouldice repair demonstrated a higher tensile strength when compared to the surrounding tissue. Strength after a Shouldice repair of the floor of the inguinal canal was found to be several times higher than could be attained under physiologic conditions. Therefore, an early postoperative return to normal activity can be recommended.
