[Research of the durability of connective tissue complexes formed in the implantation area of various types of allograft during the experiment].

The aim of the study is to examine in the experiment on the animals the mechanical properties of connective tissue complexes formed in alloplasty area using the intraperitoneal on lay mesh and sublay methodologies with further comparison of them. The experiment has been conducted on 12 rabbits of Russian chinchilla breed. Animals were distributed in the following way: the first group--operated by intraperitoneal on lay mesh methodology (n = 6) through implantation of composite grid Proceed with one-side celullose coating produced by "Ethicon" company. The second group--performed modeling of preperitoneal plastic using two-component composite grid with large-pores Ultrapro produced by "Ethicon" company (n = 6). For the tensometric evaluation of the strength of implant integration into the red wall was used entire area of anterior red wall together with the implanted transplant. According to the deflection diagrams and dynamometer rates defined the maximum burden rates which is equivalent of muscular tissue budge against polymeric matrix. Statistically significant distinctions during 14 days were not detected; however strength during 30 days in the first group was 3 times higher than in the second group. We consider that the methodology of intraperitoneal on lay mesh can be considered as operation of choice of surgery treatment of the umbilical hernias.

[Laparoscopic gastric shunting as the surgery of choice in patients with morbid obesity and concomitant methabolic syndrome].

Experience of laparoscopic gastric shunting application in accordance to the Fobi - Capello procedure in 15 patients, suffering morbid obesity (MO), was adduced. The surgical intervention technique was adduced, first results were analyzed, which are witnessing the effective lowering of the excessive body mass while followup to 6 mo postoperatively.

[Surgical treatment of duodenal fistulae].

The experience of surgical treatment of 10 patients with external intestinal fistulae was analyzed. The plot of the operation was to exlude the duodenum from the digestion by performing the retrocolic gastroenteroanastomosis after Roux or on the ultrashort loop. Early operation prevent septic complications and electrolyte disbalance. Duodenal fistulae, developed on the background of pancreonecrosis or after endoscopic retrograde cholangiopancreaticography, necessitate the external choledochial drainage.

[Surgical treatment of the patients, suffering alimentary--constitutional obesity].

The results of surgical treatment of 105 patients, suffering alimentary-constitutional obesity, using intragastric balloon placement. operative procedures of regulated gastric banding, longitudinal gastric resection, gastric and biliopancreatic shunting, were analyzed. The changes dynamics in the carbohydrate and lipid metabolism indices was estimated. Algorithm of the obesity surgical treatment, depending on the body mass index and concomitant diseases presence, was elaborated.

[Surgical tactics in the ulcer pyloroduodenal stenosis in decompensation stage].

In the ulcer pyloroduodenal stenosis the stages of complete and noncomplete decompensation are suggested. In 73% of observations, while performing an adequate preoperative preparation it was possible to convert pyloroduodenal stenosis from the stage of complete decompensation into the stage of noncomplete decompensation, in which the performance of organpreserving operation is possible. In the patients, suffering pyloroduodenal stenosis in the stage of noncomlete decompensation, resection of 2/3 of stomach is performed.

[Methods of Barrett disease diagnostics].

Chromoesophagoscopy and photodynamic diagnosis are objective methods for diagnostic Barrett disease. Those methods can give us more detailed information about morphological changes in mucosa of esophagus.
