The study assumes the results of 1010 Lichtenstein's hernioplasties. The goal of the investigation was to estimate the results in dependence of the type of the polypropylene implant. The "lite" mesh was used in 342 cases, the second group of 668 patients had the so called "heavy" mesh endoprosthesis. Comparing the early postoperative period, it was registered, that the patients of the 2nd group had statistically higher rates of wound inflammatory infiltrate - 2.7% in comparison with 0.6% for the 1st group. The late postoperative period was marked by the higher rate of neuralgia among the "heavy" group - 5.2% in comparison with 1.5% for the "lite" group. Thus, the use of "lite" mesh polypropylene implant proved to be much more preferable for the Lichtenstein's hernioplasty.
