Proposed veinextractor is used for dissection and extraction of varicose and thrombosed veins of the low limbs. It consists of thin pivot, the head of vohich looks like hemicylinder, lateral and buttend sides are made ovalshaped, conjugated between themselves and sharpened. The application of the veinextractor has enabled to decrease traumatisation and to improve cosmetic effect of the operation.
The morphological analyses of variations of colon fixation in 200 cadavers and 73 patients have been done. 3 variants of the colon position and anomalies of its fixation were distinguished. The methods of surgical correction of the colon position are recommended. 27 patients were operated on with positive results.
Examination of 305 liver specimens of human cadavers of various age and study of the findings of intravital contrast examination of the duct and vascular system in 130 patients aged from 22 to 84 years revealed changes in the architectonics of the vessels and bile ducts in pathological processes. In healthy individuals the enlargement of the length and diameter of the vessels and ducts and increase in the depth of distribution of their intrahepatic branches from the surface of the liver ware regular in character and depended on the size of the liver and the age; they were marked by a straight linear course without sharp bends and dilatations. The length, diameter, the angles at the junction, and the direction of the course of the vessels and ducts changed sharply in inflammatory processes in the liver and bile ducts, focal lesions, and cirrhosis. Irregular enlargement of the diameter of the vessels and ducts and their marked tortousness were noted. The changes in the duct system were in direct dependence on the pressure in the biliary tract, the higher the pressure, the greater was the dilatation of the ducts at all levels.
An original clamp was used in suturing a duodenal stump after gastric resection in 77 patients. The complex relief of the blades of the clamp holds the duodenum reliably during application of the sutures and ensures their air-tightness. The trauma inflicted to the duodenum in this case is minimal. During resection of the stomach in 37 patients the author used the clamp in closure of the lesser curvature. Incompetence of the duodenal stump was not encountered.

A study of 156 preparations of the liver of adults, and as well examination of 62 patients has shown, that in inflammatory processes in the liver and bile ducts, the considerable changes in the length, diameter, angles of the confluence of the bile ducts occurred. With increase in the pronouncement of biliary hypertension, their diameter increases.
