Dirofilaria immitis. A cause of pulmonary coin lesions in human beings

A patient with pulmonary dirofilariasis caused by Dirofilaria immitis is described. Only 29 other cases have been reported in the English literature. This entity has become increasingly recognized in recent years as a cause of solitary pulmonary nodules, and we suggest that it be included in the etiological consideration of coin lesions of the lung.     

Comparative evaluation of nephrotomy methods

Four methods of nephrotomy different in the means of suturing the operation wound of the kidney were studied in experiments in dogs (1--the interrupted suture with the involvement of a wide layer of the parenchyma; 2--the interrupted V-suture with the topical picture of the vessels taken into consideration; 3--the interrupted suture with the topical picture of the vessels taken into consideration; 4--the interrupted suture with hemostasis in the wound). The advantages of the 3d and 4th techniques are shown.     

Comparative evaluation of different methods of esophagogastroplasty

The experience in 102 cases of esophagogastroplasty is analyzed, different methods of formation of gastric transplant both in tumors and cicatricial stenosis of the esophagus and stomach are described. Advantages and disadvantages of 57 intrathoracic and 45 cervical esophago-gastric anastomoses with different methods of gastric tube formation are also described in detail. Overall lethality was 5.9%.     

Ultrasound scanning and invasive methods of examination of the celiac trunk and superior mesenteric artery in the diagnosis and evaluation of results of the surgical treatment of their stenotic lesions

The ultrasound duplex scanning with colored pictures of blood flow in the celiac trunk and superior mesenteric artery with occlusive lesion of them by atherosclerosis or compression by the diaphragm is a highly sensitive and sufficiently accurate research method. It allows to detect disturbances in patency of these vessels, the state of blood flow in them and to assess the results of operative treatment. A comparison of the data of preoperative ultrasound duplex scanning and aortic-arteriography has shown coincidence of the localization and, in most cases, the degree of stenosis of the celiac trunk and superior mesenteric artery. The results of direct electromanometry proved to be similar to those of dopplerography in 88% of cases before the operation and in all the cases after decompression of the celiac trunk.     

Comparative evaluation of surgical methods of rectocele correction

Sixty-three female patients with rectocele were examined before and after surgery. All the patients were divided into 3 groups. Patients of group 1 (n=22) have undergone transvaginal levatoroplasty, of group 2 (n=21)--transperineal levatoroplasty, and group 3 (n=20)--plastic repair of the rectovaginal septum with prolene net through the transperineal approach. Anatomic result, scores by Veksner's constipation scale, dejectiongraphy data (anorectal angle and prolapse of pelvic floor at rest and at dejection, depth of rectocele), sexual function. The recurrences have been revealed in 27.3% patients of group 1, in 9.5% patients of group 2, and in 5% patients of group 3. The worst functional results were achieved in group 2--a significant increase of Veksner's constipation scores (from 10.5 to 16.0), a drastic decrease of anorectal angle smoothing at dejection. The best sexual functional results were achieved in group 3--dyspareunia was diagnosed only in one patient. It is concluded that levatoroplasty should be avoided in female patients with obstructive dejection and in sexually active patients.
