It was done the analysis of the results of 625 open and endoscopic prosthetic and autoplastic hernia repairs made in a planned and emergency basis during the period from 2005 to 2012. The autoplastic group was divided into three subgroups: the plastic by Bassini, Shouldays and Postempski. The prosthesis group was divided into open and endoscopic subgroups. The open prosthesis group was also divided into subgroups in accordance with the options of hernia sac preparation (excised, reseted, untouched) and the reconstruction of the posterior wall of the inguinal canal (without reconstruction, with a single-layer and double-layer plastic). It was noted hematocele scrotum - 19 (3.04%), hematoma of the spermatic cord - 16 (2.56%), wound infiltration with a hemorrhagic component - 13 (2.08%). It was not noted the hemorrhagic complications in the subgroups of open prosthesis without hernia sac preparation. Reducing surgical aggression against inguinal hernias during the operation can reduce the frequency of hematomas. The absence of a clear classification of hematomas brings to difficulties in assessment of the role of specific surgical techniques in the development of postoperative complications after surgery for inguinal hernias.
