When analyzing original articles since the sixteenth century, it becom
es apparent that ail surgical techniques for repair of the inguinal he
rnial orifice can be traced back to two simple repair principles. The
first is reinforcement of the anterior wall of the inguinal canal and
tightening of the external inguinal ring (Stromayr 1559, Purmann 1694,
Czerny 1877), and the second is reinforcement of the posterior wall o
f the inguinal canal and the tightening of the internal inguinal ring,
either externally (Lucas-Championniere 1881, Bassini 1889, Lotheissen
1898, McVay 1942, Shouldice 1945, Lichtenstein 1987, Stoppa 1989) or
via an intraabdominal approach by laparotomy (Tait 1891) or laparoscop
ically (Ger 1990, Velez and Klein 1990). We have tried to provide a sy
stematic order to the diverse procedures of surgery of inguinal hernia
s according to their repair principles. We also point out their histor
ical development.
