[Pre- and postoperative correction of hyposiderosis in surgical treatment of portal hypertension].

In order to study iron metabolism disorders in patients with portal hypertension syndrome, to determine clinical significance of hyposiderosis and to work out effective method of its correction, 94 patients with cirrhosis of the liver complicated by portal hypertension were examined. As a result of determination of these disorders of iron metabolism methods for treatment of hypochromal anemia and hyposiderosis have been worked out. Hemotransfusions, administration of iron-containing preparation Ferrum-lec and combination of these methods were used for treatment.

[Prevertebral abscess and endotracheal intubation in patients with infectious spondylitis of cervical vertebrae].

The course of hypostatic abscess in cervical spondylitis is analyzed, and its clinico-roentgenological manifestations are presented. The differential diagnosis between prevertebral abscess and thyroid tumors is described. The modes of application of endotracheal undulation in patients with cervical spondilitis and prevertebral abscess are suggested.

[Immunomorphologic characteristics of bedsores].

Biopsies and blood of 36 patients with bedsores developing due to spinal cord trauma were studied. Pronounced alterations in the blood content of IgA, IgM, IgG, a significant increase in circulating immune complexes (CIC) content and a decrease of neutrophil leukocyte chemotactic activity were found. The authors conclude that an immune system dysfunction occurs in patients with bedsores as well as secondary immune deficiency and immunoglobulin and CIC deposition in the granulation tissue vessels.

[Minimal interventions in the surgery of osteochondrosis of the lumbar spine].

The authors consider that puncture decompression of the intervertebral disc with using the endoscopic technique and laser evaporation is a method allowing to rapidly and effectively help patients with the root syndrome. All the manipulations are made with local anesthesia. The patients started walking on the second day after operation.

[Reconstructive operations on soft tissues in the treatment of bedsores in patients with spinal injuries].

The paper presents the results of plastic operations on 54 trochanterian bedsores in 48 patients with complicated spinal injury. Early positive results were obtained in 100% of cases when various modifications of a skin-subcutaneous flap was applied in 16 patients with 17 bedsores. There were relapses in 4 patients following a year.

[Microsurgical and endoscopic laser diskectomy in osteochondrosis of the lumbar spine].

Experimental studies have revealed that a pulse surgical laser based on alumo-yttrium garnet with neodymium ensures bloodless diskectomy and evaporation of a pulposus nucleus in the volume sufficient for decompression of the intervertebral disk. Biomechanical studies of spinal resistance following puncture endoscopic laser decompression of the intervertebral disk (PELDID) and microsurgical laser diskectomy (MLD) have demonstrated that these surgical interventions fail to disturb the stability of the spinal portion operated on. A total of 75 patients with radicular syndrome were operated on with the proposed procedures: 32 with PELDID and 43 with MLD.

[Joint prosthetics using carbon implants].

A group of "Intost" materials based on carbon were developed by the I. M. Sechenov Moscow Medical Academy jointly with the Research Institute of Graphite.

[Late results of the surgical treatment of calculus-free cholecystitis].

On the grounds of the experience with 72 cases of non-calculous cholecystitis the authors describe the characteristic features and sequelae of the disease. The authors recommend to use endoscopy methods widely with the goal to differentiate this pathology from any other biliary pancreato-duodenal pathology in order to elaborate adequate surgical indications for patients suffering from non-calculous cholecystitis.

[Cancer of th e exrahepatic bile ducts].

The authors have summarized their experience with observations and treatment of 101 patients with cancer of extrahepatic bile ducts. Based on personal authors' findings it is concluded, that cancer of bile passages can frequently develop against the background of cholelithiasis. Taking into account little efficacy of surgical therapy, the prophylaxis of cancer development, namely an early operation for cholelithiasis, is believed by the authors to be the most effective measure.
