RESUMO
For the first time in experiment on animals ways of surgical treatment of 'sharp ulcer bleedings' stomach and a duodenal gut with application microporous nikelid-titanic implants are developed, the morphological picture healing processes in ulcer defect with implanted microporous nicelid-titanic plate is studied. Introduction in 'ulcer defect' microporous Ti-Ni implants, the sated 7,5% a solution capropher, provides a stable hemostasis, reduces risk of relapse of bleedings (p < or = 0,05). Possibility of performance of operations by the developed technique is proved at sharp ulcer bleedings of a stomach and a duodenal gut.

Data experimental a substantiation of a new way of formation are fluxious compression thin-large intestine anastomosis by devices from nicelid titanic alloys are cited. Advantages compression a seam in comparison with manual are shown at studying of mechanical durability, elasticity, biological tightness, a morphological picture of preparations, irrigography. The analysis of postoperative complications is carried out.

Morphological changes in the wall of the large intestine were studied after its manual suturing by a double-row interrupted suture with modern suture threads. Light and scanning electron microscopy showed "fuse properties" and "sawing effect" of polyfilament twisted threads (e.g. vicryl). Monofilament threads were free from these drawbacks and therefore were preferable. Metal elastic threads on the basis of titanium-nickelide alloys caused no inflammatory changes in tissues.

The method of creation of compressive terminal colon anastomosis with implants of TN-10 titanium nikelid was developed. Experimental studies carried out on 60 mongrel dogs demonstrated higher physical strength and biological containment of these anastomoses compared with manual and mechanical ones. Regeneration completed earlier after surgery and was accompanied by less inflammation. Clinical study was carried out in 54 patients. There were no lethal outcomes, insufficiency of anastomosis was seen in 1 (1.9%) case.

The article analyses the treatment of hemorrhoids in our country and abroad, where outpatient treatment with latex rings is applied most frequently. The authors conducted 238 hemorrhoidectomies under conditions of outpatient clinics. They developed an operative method consisting in preventive compression of the base of the hemorrhoids with designs of alloy with "memory" of the shape. This method was used in 118 hemorrhoidectomies. No life-threatening complications occurred. Late-term recurrences were recorded in 1.6% of cases. It is claimed that hemorrhoidectomy can be performed in outpatient clinics if certain rules are observed. The is convenient for the patients and economically profitable for the State.
