[Current methods of surgical treatment of perforated pyloroduodenal ulcers]. / Sovremennye sposoby khirurgicheskogo lecheniia perforativnoi piloroduodenal'noi iazvy.

Because of the unsatisfactory long-term results, closure of a perforative duodenal ulcer should be performed in exceptional cases, for strict indications. At the modern stage of the development of surgery, vagotomy with organ-preserving operation is the most substantiated method for treating a perforative pyloroduodenal ulcer. In choice of a method of vagotomy, it is expedient to form the clinical groups. Use of vagotomy at the toxic stage of peritonitis (up to 18 h from the moment of perforation) do not lead to deterioration of the immediate results of the operation and is substantiated pathogenetically. Total postoperative lethality was 4.6%. The main cause of death together with delayed performance of the operation was a pronounced character of concomitant diseases. After vagotomy with the organ-preserving operation, there were no lethal outcomes.

[New method of thymus transplantation]. / Novyi metod transplanatatsii vilochkovoi zhelezy.

A surgical procedure for correction of T-system immunity deficiency in primary immunodeficient states and malignant neoplasms in children is described. To ensure a high physiological activity of the transplant, to prevent anti-recipient reaction and to maintain laminar blood flow in the transplant, thymus glands were obtained from fetuses and separated from breast bone. Blood channel reconstruction was performed before the gland transplant was washed and connected to the patient's blood flow. Thymus transplantation was carried out in 25 cases and neither acute rejection nor anti-recipient reaction were observed. Immune response indices returned to normal within 6-7 months.
