154 patients in the late period of closed trauma of spinal cord were followed up, 40 patients were examined by means of MRT method. There was a progredient course of disease in 20.3% of cases, mainly in patients with compression of spinal cord.

The analysis of results of magnetic resonance tomography was performed in 289 patients with neurological complications of lumbar osteochondrosis. Among such patients radicular and reflectoral syndromes were observed in 184 patients while diskogenic lumbar-sacral radiculomyeloischemias--in 105 ones. The high informativity of the method was demonstrated in visualisation of localisation, direction and sizes of intervertebral disks' hernias at lumbar osteochondrosis as well as in establishment of such factors which predisposed diskogenic radiculomyeloischemias' development.

A total of 44 patients with sequelae of spinal injuries in the periods of 2 months to 46 years were studied by X-ray, neurological and NMR techniques and divided into 3 groups: (1) those with open injuries, (2) those with closed injuries concurrent with compression of the spinal marrow and/or roots of the cauda equina; 3) those with closed injuries without compression. It was shown that NMR tomography enabled the status of the vertebral canal and spinal marrow to be assessed and indications for surgical interventions to be specified. Spinal compression may in later periods result in post-traumatic progressive myelopathy appeared as atrophy of the spinal marrow and myelomalacia (with cyst formation in 18% of cases).

Magnetic resonance tomography (MRT) was used in examinations of 172 patients with spinal cord abnormalities. Thirty-eight cysts were detected: 25 in syringomyelia, 5 in intramedullary tumors, 4 posttraumatic and 4 postoperational ones. Based on the MRT patterns, two types of syringomyelia were distinguished, the occlusive and idiopathic ones.

The production of autoantibodies (AAB) to the specific antigen of myelin-containing components of the nervous tissue galactocerebroside (GalC) was revealed in 117 patients with traumatic injuries to the spinal cord of various severity in periods of 18 months to 46 years after the injury. The degree of nervous system destruction, the type of the course of posttraumatic myelopathy, and the level of production of AAB to GalC were found interrelated. The existence of AAB provides evidence of sensitization of the immune system to nervous tissue antigens in spinal cord injury, while the level of AAB to GalC reflects the activity of the continuing destructive process due to the injuring effect of AAB under conditions of impaired permeability of the blood-brain barrier and shows the desirability of desensitization therapy.

Since 1982 the authors perform early (on the 4th-10th day) reoperations in extensive necroses of the sigmoid colon which had been transposed downwards after abdomino-anal resection of the rectum. The reoperation consists in resection of the affected segment of the intestine (usually the whole remaining sigmoid colon) and downward retransposition of the descending or the left half of the transverse colon. Nine such operations were performed; in 8 patients the results were favorable, one 70-year-old female patient died.

Echoencephalographic data on the ventricular system in 66 patients during the acute period of cerebral concussion are reported. Forty-seven of them showed statistically significant signs of mild intracranial hypertension. Fourteen out of 31 subjects who had a repeated examination prior to discharge from the hospital displayed no improvement in their echoencephalographic parameters.

The work analyzes the first twelve observations of a through ilioperineal drainage after simultaneous abdomino-perineal extirpation and abdomino-anal resection of the rectum. The authors present convincing data concerning high efficiency of the proposed method of drainage. It has a number of advantages over other methods: it markedly accelerates the healing of the postoperative wound, preventing postoperative complications (suppurations, retroperitoneal phlegmons etc).

The paper analyzes the complex clinico-experimental studies carried out by the surgeons, endoscopist, roentgenologist, and morphologist. Under special attention were the immediate and the late results of such variants of plastic and reconstructive operations on the large intestine when the remaining right portions of the large intestine were used for the substitution of defects of the left ones (coloplasty). Per 120 plastic and reconstructive operations there were 38 complications with 5 lethal outcomes (4,1%).

The analysis of 257 radical operations of the rectum for cancer, made comparatively for 2 decades period, indicated that the increase of the experience and skill of surgical specialists and current successes in practical surgery and anesthesiology ran parallel to the increased amount of sphincter-preserving operations - from 15% in 1964 to 52% in 1976. The advantages of abdomino-anal resection with a pull-through procedure are emphasized.

To precisely determine the process spread in gastric cancer, in 90 patients left prescalene biopsy was performed simultaneously with the operative procedure on the stomach. In 20% of the patients the histological examination of serial sections showed gastric cancer metastases in non-enlarged supraclavicular lymph nodes. In vast majority of the observations a supraclavicular metastasis diagnosed only histologically was a manifestation of the tumor process spread.
