Not long after Lichtenstein and Shulman (1986) introduced their subaponeurotic repair, Nyhus (1989) expressed concern regarding subprosthetic incarceration. Even though interstitial recurrence was not encountered over the subsequent decade or more, one of us (AIG) was referred three cases over the past 3 years. Two men and a woman suffered from chronic inguinodynia 1-6 years following a Lichtenstein procedure for unilateral primary inguinal herniation. A mass, in an unusual location (spigelian line) was palpated in one, the other two required ultrasound studies for diagnosis. All at surgery revealed indirect sacs, and one also had a separate protrusion in the lateral triangle of the groin. Two were repaired laparoscopically, the other using a bilayer connected prosthetic device. Our hypothesis is that this painful complication is now appearing because of recent modifications to the operative technique. An overlay lax dome-shaped prosthesis cannot be relied on to always initially collapse the inguinal canal. Mini-dissection, by limiting exposure, may prevent placement of the keyhole in the mesh close enough to the internal inguinal ring. Studies are under way to determine the validity of these conclusions. [ABSTRACT FROM AUTHOR] |
