[Tension-free plasty in the surgery of abdominal wall hernias].

The article presents an experience with application of tension-free plasty of the anterior abdominal wall using reticular endoprostheses. New endoprostheses of Reperen are developed and applied, a method of sutureless fixation of polypropylene net in the abdominal wall tissues is proposed when performing plasty for great ventral hernias. Advantages of new methods are shown compared with analogs both in selective and in emergency surgery, in different age groups of patients.

[Experimental-clinical reasons for application of endoprostheses of reperen for plasty of the abdominal wall].

The work presents results of a morphological investigation of tissues in the zone of implantation of synthetic material in creation of experimental model of ventral hernia. A comparative characteristic of a reaction of tissues on reperen and polypropylene is given. A number of principal advantages of reperen as compared with polypropylene were detected in plasty of hernial hilus.

[Comparative assessment of short-term outcomes of cholecystectomy in minimally-invasive surgical procedures for chronic calculous cholecystitis].

A randomized blind trial was carried out for comparative evaluation of short-term results of surgical treatment of chronic calculous cholecystitis in 100 patients after laparoscopic cholecystectomy and in 100 patients after minimally-invasive cholecystectomy. Both groups contained geterogenous patients (morphology in gall bladder zone, concomitant diseases). Statistically significant (p=0.
