ABSTRACT
The paper provides a comparative analysis of the results of treatment in the patients with disk hernia at the lumbosacral levels, who have been endoscopically operated on by a modified procedure described by J. Destandau and by the routine procedure. In the study group, 58 patients (31 males and 27 females) were operated on. The results of treatment were assessed, by using the MacNab spinal endoscopic intervention scale: there were good results in 88% of cases, fair results in 8.6%, and poor ones in 3.4% (2 patients). In the control group, these were 77.4, 17.8, and 4.8%, respectively. The procedure proposed by the authors for fenestration of the intervertebral disk may extend indications for endoscopic diskectomy and its capacities in ossified disk hernias. Two-stage traction of the root may minimize its injury, particularly in herniated median and paramedian disks.

The paper presents the results of morphological study of 668 cases of adenomas of the hypophysis on the basis of light optical and electron microscopy techniques, immunohistochemical analysis and a number of other methods. Correlation between cellular, tissue and hormonal characterization of adenomas and their capacity for invasive, infiltrative growth and relapses have been studied.

In 5 of 35 patients who died from giant adenomas of the hypophysis the tumor invaded the orbit through the superior orbital suture from the cavernous sinus. All five patients had hormonally active hypophyseal adenomas. Analysis of the neuroophthalmological complex of symptoms revealed the presence of a marked chiasmal syndrome combined with mild exophthalmos and oculomotor disorders. These data together with the results of X-ray diagnosis may show the degree of tumor spread.
