[Computed tomography in the diagnosis of salivary gland neoplasms].

To evaluate the efficiency of computed tomography (CT) in the diagnosis of salivary neoplasms, 68 patients (50 with benign tumors of the salivary glands, 10 with theirs malignant tumors, 8 with salivary cysts) were examined. The authors revealed the high informative value of CT in the diagnosis of salivary bulky lesions. CT defined the site of a tumor, the benign or malignant pattern of its growth, the extent of tumorous invasion.

[Computed tomography of the pleura].

The paper examines CT images of the pleura and interlobar culci in health and in disease. For this, 403 patients were examined (420 CT studies), of whom 218 had pleural lesion and 185 formed a control group. The complex of studies involved computed tomography (CT) as compared with conventional radiation studies.

[The functional results of distal subtotal gastric resections in cancer patients].

It was clinically proven that a gastrojejunostomy with Rue-type anastomosis, following the subtotal gastric resection has better functional results. This method does not cause as many late postoperative disorders as Billroth I and Billroth II operations. So, it is better to use the Rue-type anastomosis for treatment of distal stomach cancer stage I-III.

[X-ray semiotics of sialolithiasis in functional digital subtraction sialography].

Twenty-seven patients with sialolithiasis were examined using functional subtraction sialography developed by the authors. Differential diagnostic signs characterizing the degree of involvement of the salivary gland were defined. High efficacy of the method helps correctly plan the treatment strategy.

[The etiology of sialolithiasis].

The authors have revealed dilatation of the excretory ducts of salivary glands involved in sialolithiasis and of other salivary glands in a patient. A hypothesis on the primary etiological role of ductal ectasia in the development of sialolithiasis in case some other additional factors are present is put forward. The authors recommend resorting to computer-aided tomography and functional digital subtraction sialography of the salivary glands for the diagnosis of sialolithiasis and discuss the advantages of these methods in comparison with other ones.
