The results of treatment of 221 patients for inguinal hernia, including preperitoneal hernioplasty in 117 and hernioplasty according to Lichtenstein method in 104 of them, were analyzed. After the operation the testis shells watering had occurred in 6 patients, the postoperative cicatrix infiltrate--in 6, operative wound hematoma--in 4. The hernia recurrence had occurred, while fol-lowing patients up from 6 months till 4 years, in one patient only after operation, performed according to Lichtenstein method. In patients, to whom preperitoneal plasty of inguinal canal was per-formed, a specific complications, associated with the operation performance, were absent. Preperitoneal plasty secures a safe strengthening of hernial gates. The net implant fixation in preperi-toneal space permits to escape the feeling of a "foreign body" pres-ence in inguinal area of the patients.
