THE REDUCTION en masse of a groin hernia is an extremely rare occurrence, as evidenced by the fact that to date only about 200 cases have been recorded in the world literature. This entity may be defined as a displacement of a hernia tumor without relief of the incarceration or strangulation. It was first described in 1702 by Saviard. In 1931, Pearse made an extensive review of the world literature and was able to collect 190 cases, including one of his own.7 He stated that reduction en masse has a frequency of one in 13,000 herniae. In 1941, Casten and Bodenheimer found 15 cases and added two of their own.9 A further ten cases have been reported by Wolfe, 1939; Cole, 1941; Cooley, 1942; Crowe, 1943; Chappell, 1950; Bailie, 1953; Millard, 1955; Murdock, 1959; Renton, 1962; and Brady, 1964.* Since forcible taxis has been abandoned and emphasis placed
