Objective of the research is to study strength properties of author’s enteroenteroanastomosis single-layer suture by the method of pneumompression. Matherial and Methods. Experiment was carried out on 45 rabbits of «butterfly» breed. There were three groups of animals. Author’s single-layer precise suture was fulfiled in the first group. Author’s single-layer precise interrupted suture was made in second group rabbit. In third (control) group Albert-Schmieden suture was used. Animals were taken off the experiment on 1, 3, 5, 14 and 30 days after a surgery. Strength properties were studied at the same terms by pneumopression. Results. Anastomoses pneumopression displayed progressive decreasement of strength properties in both precise suture groups to third day up to 111.2±1.7 and up to 98,3±6,0 mm.Hg. in a control group. Strength decreasement for both precise suture groups came to 16.2%, whereas for control group - 36%. Rupture pressure was rising from fifth day in precise suture groups up to 120.7±2.4 mm.Hg., and to 114.3±7.0 mm.Hg. in the control group to 198,8±3,8 and 172,0±8,5 mm. Hg correspondently in the second week of postoperative period. Futher data not significantly changed. Conclusions. Single-layered precise suture techniques of anastomoses formation with microsurgery showed to be beneficial as for Albert-Shmiden’s suture rupture pressure was much more variable in all stages of repair. It demonstrates authentically better outcomes in author’s single-layer precise intestinal suture methods.
