[The influence of anatomical and functional failure of the abdominal wall on the prognosis of postoperative ventral hernias].

It was analyzed the results of clinical and ultrasound examination of the abdominal wall in 180 patients with different surgical diseases of the abdominal cavity. All patients were divided into 3 groups of 60 persons on the basis of the preoperative examination results. The first group included patients without clinical and ultrasound disorders, the second and the third - with mild and severe anatomical and functional failure of the abdominal wall.

[Influence of lifting of muscular aponeurotic tissues of the hypogastrium area on quality of life in abdominoplasty patients].

An analysis of complex clinical and ultrasonic investigations of the abdominal wall and the following surgery in 42 women with ventral hernia of big size accompanied by the ptosis of the abdomen was made. The patients were divided into two groups, each consisting of 21 patients.The endoprosthesis replacement of defect of the abdominal wall was made with standard polypropylene implant in the first group.

[The choice of polypropylene endoprosthesis for abdominal wall plasty].

The study (on 27rabbits) of postponed tissue reaction of abdominal wall was done after web space plasty of standard, light and superlight polypropylene endoprostheses on 30th, 60th and 120th days. It was stated, that the standard polypropylene prosthesis was the most suitable for endoprosthesis replacement of abdominal wall in strangulated ventral hernia. The light polypropylene endoprosthesis should be used in the uncomplicated hernia.

[Indications and results of preventive endoprosthezing of the abdominal wall during operations on organs of the abdominal cavity and retroperitoneal space].

Complex examination and treatment of 120 patients with anatomo-functional insufficiency of the abdominal wall was made after operations on organs of the abdominal cavity and retroperitoneal space. In the 1st group (60 patients) the abdominal wall was sutured by traditional methods. In the 2nd group (60 patients) laparotomy was followed by implantation of polypropylene endoprosthesis by over-aponeurotic method, and suturing of the lateral wall--by sub-aponeurotic method.

[Comparative assessment of national and foreign endoprostheses for hernioplasty].

The used foreign endoprostheses have redundant strength, and great number and stiffness of implanted material might be a cause of complications and result in patients' discomfort associated with decreased mobility of the anterior abdominal wall. Less material consumption of endoprostheses results in increased porosity and less thickness facilitating rapid integration of the grid into the elastic and strong connective tissue scar. Company "Lintex" has developed and produced endoprostheses from polypropylene and polyvinylenfluoride monothreads in heavy, standard and light version, which allows their choice with a glance to the particular surgical situation.

[Prophylactics and treatment of postoperative hernias of the lateral abdominal walls using polypropylene endoprosthesis].

An analysis of complex examination and treatment of 151 patients after planned and performed surgical interventions on organs of the retroperitoneal space was made. The patients were divided into 4 groups. The first group (of comparison) included 46 patients who were treated by lumbotomy for different diseases of organs of the urinary system.

[The application of immobilized forms of sodium hypochlorite in complex treatment of diffuse purulent peritonitis].

Complex examination and the following treatment of 380 patients with diffuse purulent peritonitis were analyzed. The patients were divided into 2 groups. The first group included 245 patients to whom the sanitization of the abdominal cavity used traditional antiseptics.

[A new approach to treatment of the intraabdominal hypertension syndrome in patients with diffuse peritonitis].

Results of treatment of 49 patients with diffuse purulent peritonitis were analyzed. The patients were divided into two statistically similar groups. The control group of patients consisted of 27 patients treated using traditional methods.

[Quality of life after operations in the abdominal and retroperitoneal cavities: the influence of the abdominal wall anatomic-functional insufficiency].

120 patients with abdominal wall anatomic-functional insufficiency were examined and treated. All patients were divided in 2 similar groups 60 patients each. Patients of the first group had traditional laparotomy wound closure, whereas patients of the second group overcame polypropylene mesh implantation.

[The efficiency of antiadhesive means with "mezogel" having a barrier effect after dissection of the adhesions in patients with acute adhesive intestinal obstruction].

An antiadhesive absorbable means "Mezogel" produced by the firm "Lintex" (St. Petersburg) after intraperitoneal administration to animals in experiments was shown to reliably effectively reduce the degree of a recurrent adhesion process, and in 40% of the cases to completely prevent repeated formation of adhesions in the abdominal cavity. The use of "Mezogel" for intraperitoneal administration after dissection of adhesions in patients with acute adhesive intestinal obstruction results in relieving the course of the nearest and long term postoperative periods and reducing the number of recurrences, thus improving quality of life of the patients.

[Meshed implants of polyvinylidene fluoride in treatment of abdominal wall hernias].

The authors analyze the results of experimental and clinical investigations for comparative studying a new meshed implant of polyvinylidene fluoride as an endoprosthesis of the anterior abdominal wall with postoperative hernias. It was shown that the polyvinylidene fluoride prosthesis is a good alternative of polypropylene prosthesis. Its physico-chemical properties allow reliable prostheses of the abdominal wall, and its biological compatibility is higher as compared with polypropylene prosthesis.

[Prophylaxis of postoperative ventral hernias with polypropylene endograft].

Results of clinical examination of abdominal cavity at 450 patients with various abdominal surgical diseases are analyzed. Special scale has been developed for risk assessment of postoperative hernia, identification of absolute and relative indications for abdominal endografting. Overall 47 patients according to absolute indications underwent preventive plastic surgery with polypropylene endograft during abdominal operations.

[Preventive plasty of the abdominal wall with endoprosthesis "Esfil" in operations on organs of the abdominal cavity].

An analysis of clinical and US investigations of the abdominal wall in 210 patients with different surgical diseases of the abdominal cavity allowed division of the patients into three groups: without clinical and ultrasonic alterations, with a mild degree and with a severe degree of the anatomo-functional weakness of the abdominal wall. Indications for preventive endoprosthesis of the abdominal wall were determined using the method of quantitative evaluation of risk factors of postoperative hernias developed by the authors. Preventive endoprosthesis of the abdominal wall with a polypropylene endoprosthesis "Esfil" was fulfilled during operation on organs of the abdominal cavity in 11.

[The tension-free hernioplasty with a polypropylene endoprosthesis "Esfil" in patients with incarcerated abdominal hernias of great and giant size].

In experiments in 24 rabbits it was found that endoprosthesis had no negative effects on the course of the wound process and did not prevent elimination of infection from the wound. "Esfil" was used for plasty of the abdominal wall in 38 patients with incarcerated postoperative, umbilical and inguinal hernias of great and giant sizes. No patient had rejections of the synthetic material, no recurrent hernias during the first year after operation.

[Choice of a method of plasty of the anterior abdominal wall in patients with postoperative ventral hernias].

The individual characteristics of the structure of the anterior abdominal wall were studied for revealing the anatomical preconditions for the formation of postoperative ventral hernias in order to substantiate efficient methods of surgical treatment. It was established that patients with brachiomorphous build had anatomical features facilitating the formation of ventral hernias. The greatest strength of the fascio-aponeurotic complex of the anterior abdominal wall is characteristic of patients with a dolichomorphous constitution, while the least strength of the fascio-aponeurotic complex of the anterior abdominal wall is characteristic of patients with brachiomorphous constitution.

[The experimental grounds and clinical application of domestic endoprosthesis "Esfil" for plasty of the abdominal wall].

An investigation of physico-mechanical properties and a histological examination of meshed endoprostheses "Esfil" ("Lintex" St.Petersburg) and nets "Prolene" ("Ethicon") implanted into the abdominal wall of 66 Chinchilla rabbits was carried out under experimental conditions. The comparative experimental investigation has shown that both materials possess sufficient physico-mechanical properties to resist intra-abdominal pressure and when implanted they cause an inconsiderable inflammatory reaction followed by the formation of a solid connective tissue capsule.

[An epidemiological study of herpetic viral infections in the Republic of Byelarus].

Studies on the epidemiology of infections caused by Herpes simplex virus, cytomegalovirus and Epstein-Barr virus in different age groups of the population of the Republic of Belarus, carried out over the period of many years, are summarized. The frequency of clinical manifestations of different forms of herpetic viral pathology in newborns, children and adults in different regions of the republic was studied. More frequent cases of the most severe clinical forms of herpetic viral infections (encephalitides, generalized infection) were noted in persons having immunodeficient states of different etiology, as well as among the population residing on the territory with unfavorable radiation conditions as a consequence of the catastrophe in the Chernobyl nuclear electric power station.

[The clinico-electrophysiological assessment of the efficacy of microwave resonance therapy in the rehabilitative treatment of patients with cerebral palsy in the form of spastic diplegia].

As indicated by EEG and EMG data, adjuvant microwave resonance therapy included in the complex of routine aftertreatment of 24 children with spastic diplegia improved therapeutic efficacy and promoted positive trends in the patient's condition of 63% of those treated. The changes in ENMG parameters induced by microwave resonance therapy reflect shifts in the function of peripheral neuromotor system via optimisation of suprasegmental effects.

[In vitro activity of surgical suture materials containing cephalosporin antibiotics].

Surgical threads containing cefazolin and cefoperazone were studied comparatively. Cefazolin was shown to incorporate into the structure of caproamide threads in an amount of 20 per cent by the thread weight while the cefoperazone incorporation amounted only to 3.7 per cent.

[Use of polypropylene single thread as the suture material].

The authors studied the results of using polypropylene monothread as suture material in 254 patients who underwent planned and emergency operations for various diseases. It was found that polypropylene monothread used for suturing the skin, deeper located tissues, granulating wounds is sufficiently elastic, acapillary, strong, and biologically inert owing to which there is no need to remove it until complete healing of the wound even in considerable exposition. The monothread causes a less traumatizing effect than does a thread of natural silk when drawn through the tissues.
