In 79 patients with duodenal ulcer disease, the selective proximal vagotomy (SPV) with the use of the "Scalpel-1" CO2-laser was performed. In the experiment, it is shown that after dissection of the nerve trunks by the laser scalpel, no regeneration of neural tissue is observed. After laser SPV, the suppression of gastric acid production is more stable than after conventional vagotomy, the number of ulcer recurrences is lower.

[Percutaneous transhepatic cholangiography and cholangiostomy in mechanical jaundice]. / Chreskozhnaia chrespechenochnaia kholangiografiia i kholangiostomiia pri mekhanicheskoi zheltukhe.

Under investigation there were 223 patients with mechanical jaundice, 132 patients were subjected to percutaneous transhepatic cholangiography, 102 patients--to percutaneous transhepatic cholangiostomy. The preoperative drainage of bile ducts was established to be efficient in order to reduce lethality. High diagnostic value of cholangiography is shown. Indications and contraindications to the application of cholangiostomy depending on etiology of jaundice, localization of the tumor, and its spread, degree of hepatic insufficiency and risk of operative procedures are formulated.
