Prevention of ischemic orchitis during inguinal hernioplasty.

Ischemic orchitis and testicular atrophy remain the most dreaded complications of inguinal hernioplasties. The current study examines these complications in a series of hernia repairs during a period of 20 years. The incidence of the complications in the ten year period from 1971 to 1981 was compared with the experience since 1981, from which time all distal indirect hernia sacs were left in place and increasing experience was gained in properitoneal repairs of recurrent hernias. The incidence of ischemic orchitis in primary hernia repairs was reduced from 0.65 per cent (11 instances in 1,682 repairs) to 0.03 per cent (one in 3,634 repairs). The incidence in recurrent hernia repairs was reduced from 2.25 per cent (seven in 311 repairs) to 0.97 per cent (eight in 827 repairs). These data have led us to emphasize the importance of minimizing cord dissection by leaving intact all significant distal hernia sacs and not dissecting beyond the pubic tubercle. Additionally, properitoneal repairs should be considered for repairs of recurrent hernias not only to reduce further recurrences but also to avoid testicular complications.
