Recurrences after prosthetic repair of inguinal hernias by the lichtenstein technique

Abstract

We report a 3.4% incidence of hernial recurrence (all recurrences were reoperated) after inguinal hernia repair by the Lichtenstein technique: 14 reoperated recurrences (in 13 patients) in a series of 440 inguinal hernias (375 primary and 65 recurrent) in 379 patients (62 bilateral) over 5 years (1994–1998). Some 2/3 of all recurrences appeared within a year of surgery. Eleven of these patients were operated on for bilateral and/or recurrent groin hernia, and eleven also showed at least one risk factor for recurrence, such as obesity and other general diseases (specially pulmonary and hepatic). The incidence of recurrence was 0.7% (2 in 272) for primary unilateral hernia, 3.8% for primary bilateral hernia (2 in 52), 11.1% for recurrent unilateral hernia (5 in 45) and 40% for recurrent bilateral hernia (4 in 10). Recurrences were 5 indirect hernias, 4 direct hernias and 5 femoral hernias. Indirect recurrence was attributed to technical errors, but femoral and direct hernias seem to be the consequence of a poor indication for the Lichtenstein technique. Log-rank tests showed very significant statistical differences (p<0.01) in the risk of hernial recurrence between recurrent and primary hernias. We suggest that certain conditions should be contraindications for the standard Lichtenstein technique (bilateral groin hernia, recurrent hernia, obesity, chronic pulmonary and liver disease), and propose for these either a preperitoneal repair or some modifications of the Lichtenstein technique (an extremely floppy mesh and simultaneous femoral repair with the mesh).
