Компрессионный способ анастомозирования толстой кишки имплантатами с памятью формы - альтернатива традиционным швам

Research objective. To prove experimentally the possibility of forming a compression colonic anastomoses using nickel-titanium devices in comparison with traditional methods of anastomosis. Materials and methods. In experimental studies the quality of the compression anastomosis of the colon in comparison with sutured and stapled anastomoses was performed. There were three experimental groups in mongrel dogs formed: in the 1 st series (n = 30) compression anastomoses nickel-titanium implants were formed; in the 2 nd (n = 25) – circular stapling anastomoses; in the 3 rd (n = 25) – ligature way to Mateshuk– Lambert. In the experiment the physical durability, elasticity, and biological tightness, morphogenesis colonic anastomoses were studied. Results. Optimal sizes of compression devices are 32 × 18 and 28 × 15 mm with a wire diameter of 2.2 mm, the force of winding compression was 740 ± 180 g/mm 2 . Compression suture has a higher physical durability compared to stapled (W = –33.0; p < 0.05) and sutured (W = –28.0; p < 0.05), higher elasticity (p < 0.05) in all terms of tests and biological tightness since 3 days (p < 0.001) after surgery. The regularities of morphogenesis colonic anastomoses allocated by 4 periods of the regeneration of intestinal suture.  Conclusion. Obtained experimental data of the use of compression anastomosis of the colon by the nickel-titanium devices are the convincing arguments for their clinical application.
