Here are represented our results according to making and clinical using of different TiNi devices for treatment of digestive system diseases. Constructions for perfoming of compression anastomoses, cliping of tubular structures during laparoscopic operations and perforated ulcer plastic. Materials of experimental investigations and clinic experience of 220 cases treatment are represented.

The reduction of the endoscopic methods of the inguinal hernia surgical treatment to the everyday practice of the surgery departments led to the better results of treatment. However, the recurrence rate remain sat the level of 2.2-4.4%, and the rate of the intraoperative and postoperative complications is 8%. The paper describes treating 78 patients (59 pations underwent the reduction of the endoscopic methods of the inguinal hernia surgical treatment to the everyday practice of the surgery departments led to the better results of treatment and 19 patients underwent the laparoscopic transabdominal hernia repair with the usage of porous nickelid titanium. in the period from 2000 to 2016. It shows a procedure of installing porous nickelid titanium, gives the obtained results of the procedure and analizes the experience of world literature. The procedure of the laparoscopic hernia repair allows to lessen the injury rate of the surgery, to lessen the possibility of the postoperative complications and to simplify the medical staff work.

The article contains the results of a study of nickelid titanium devices used for the formation of compression anastomoses in patients with digestive system diseases and describes the techniques of compression fistula formation using these devices.Besides, the article presents clinical experience in the formation of anastomoses between the organs of gastrointestinal tract for the treatment of eighty-seven patients with various pathologies of digestive organs. One hundred and nine compression anastomoses were applied in our clinic. Anastomotic dehiscence was found in three cases (2,7%) which are described in details in the article. In all patients, the devices evacuated from the digestive tract in a natural way. The average period of device rejection accounted for 14 days. Fibrotic scope examination performed after an operation showed that created anastomoses corresponded to the dimensions of used structures. A soft scar by primary healing type was formed on the parts with compression anastomosis. Using nickelid titanium devices for the formation of compression anastomoses between the gastrointestinal organs will improve the quality of fistula formation, reduce mortality and postoperative complications.

А review of domestic and foreign literature on compression methods for the formation of colonic anastomoses is presented in the paper.Despite advances in the improvement of the manual suture of the colon, the frequency of postoperative complications remains high – 68.7%, while mortality ranges from 1% to 26%. Thus, it was not possible to achieve the absolute reliability of the traditional manual suture in the formation of colonic anastomoses.Compression anastomosis has an advantage over manual. When forming an anastomosis using a compression method, a decrease in time was noted, ease of creating an anastomosis, a significant decrease in postoperative complications and a high quality of the formed anastomoses, confirmed by morphological studies.

Summarizing the experience of research and treatment of 218 patients (134 (61.5%) men and 84 (38.5%) women) with pathological symptoms frolicking after surgery on the stomach and duodenum. The average age of patients was (56.7 ± 13.7) years old. The authors formulated the obligatory scope of examination of patients to select possible options for reconstruction of the gastrointestinal tract. The results of the developed methods are demonstrated, confirming the need to restore the natural passage of food, and, if necessary, the creation of functionally active formations that prevent the occurrence of a retrograde pathological flow of contents from the distal parts of the digestive tract to the proximal.
