[Primary multiple colorectal cancer in elderly patients].

Primary multiple malignancy or polyneoplasia, which is regarded as an one-time or a sequence of malignant focal formation, is by no means a rarity nowadays. However, its treatment involves quite an array of complex problems. Primary multiple malignancy frequency ranged 0.04-11%.

[Experience in surgical treatment of injuries of the major vessels].

Eighty-one patients were treated for injuries to the main vessels. They underwent operations at the Novgorod Regional Hospital and in surgical departments of the Novgorod Region. The injuries of the vessels were open in 90.1% and closed in 9.9% of patients. Among 125 reconstructive operations good results with restoration of arterial and venous blood flow and maintained function of the limb were produced in 67.9% and satisfactory results in 9.9% of patients. Amputation of the limb was carried out in 13 patients (16.0%). Mortality was 7.4% (six patients). The authors emphasize that early admission of patients to the hospital and the therapeutic tactics in a vascular trauma guarantee preservation of the injured limb, restoration of its function, and save the patient's life.

[Surgical treatment of recurrent aortic-iliac-femoral occlusions].

At the department of vascular surgery of the Novgorod Regional Hospital 455 reconstructive operations for atherosclerotic occlusions in the aorto-ileo-femoral segment were performed in 1984-1991. Thrombotic reocclusion occurred in 58 patients (12.7%) for which a second operation had to be conducted, early thromboses of the reconstructed segment were encountered in 16 patients (3.5%) and late thromboses in 42 (9.2%). The work analyses the causes of early and late reocclusions, substantiates the surgical tactics, and discusses the technical characteristics of the operation. Thrombectomy with reconstruction of the distal anastomosis and the draining paths was the main method of treatment. It was conducted in 12 patients with early and in 21 patients with late reocclusions. The results of surgical treatment are shown. It is concluded that repeated reconstructive operations are a sufficiently effective measure for preserving the function of the earlier operated on limb; they made it possible to produce positive immediate results in 81.0% and late-term results in 64.3% of patients.

[Artificial normovolemic hemodilution with preoperative blood preservation in reconstructive operations in the aorto-iliac region].

The artificial normovolemic hemodilution allows to improve results of planned aortobifemoral shunts in patients with the Leriche syndrome. The method was used in 45 of 138 operations of this kind. The level of postoperative complications was reduced from 33.3% to 22.2%, that of anemia--from 25.8 to 13.3%, postoperative lethality became lower (from 11.8 to 4.4%).

[Surgical treatment of occlusive diseases of the brachiocephalic arteries].

Experience of the department of vascular surgery of the Novgorod Regional Hospital from 1985 is analysed. The department has the standard sets of instruments, equipment, and roentgenodiagnostic apparatus which allow catheter, selective, and puncture angiography to be carried out. Thirty-six operations were performed on 28 patients. All were conducted under endotracheal anesthesia with medicamentous protection of the brain. One patients died from reflex cardiac arrest. No complications occurred in the other operations and their results were positive. It is concluded that reconstructive operations on the brachiocephalic trunks can be successfully performed in angiosurgical departments of regional and city hospitals with a personnel skilled in diagnosis and a trained angiosurgeon and anesthesiologist on the staff.

[Postoperative mortality in acute cholecystitis and various ways of its reduction].

Operations were performed on 1166 patients with acute cholecystitis in a group of surgical hospitals of the Novgorod region in the period from 1983 till 1986. Sixty eight of them died (5.8%). Among the immediate causes of death the first place is occupied by purulent complications, the second place -- by acute cardiovascular insufficiency. It is stressed that elderly and senile patients prevailed among those who died after operations for acute cholecystitis (83.8%). The role of timely admission to the hospital and early operations of patients with acute cholecystitis in getting favourable results is stressed.
