[Surgical treatment of bronchial fistulas after pneumonectomy].

The results of surgical treatment of 9 patients with bronchial fistulas after pneumonectomy have been analysed. During the reoperation the bronchial stump was wrapped by the omental flap with vascular pedicle (omentoplasty). In 6 patients omentoplasty was used in urgent repeated transpleural operations, in 3--during the late operations from transsternal transpericardial approach. Wedge resection of the tracheal bifurcation with omentoplasty from transsternal transpericardial approach was performed in 2 patients with a short bronchial stump. 2 patients died after surgery: one--from cardiopulmonary failure, the other one--from the relapse of bronchial fistula. Omentoplasty in patients with primary bronchial fistulas proved to be effective. It is advisable to perform reoperations during the 1st day after complications developed.

[Balloon-catheter devices for selective administration of drugs into portal veins].

A balloon-catheter device was designed by means of which part of an organ or zone of the abdominal cavity can be isolated for their administration of medicinal preparations for diagnostic and therapeutic purposes. The authors suggested a new method for regional perfusion-infusion in diffuse and local diseases of the liver and the organs of the pancreaticoduodenal zone. It makes it possible to supply the drug to the pathological process by the drip and stream method at a rate similar to that of physiological blood flow. The method was used in a complex with surgery in 73 patients with diffuse and localized diseases of the pancreas, liver, biliary system, and spleen. The result was positive in 60 patients. The method is recommended for application in surgical clinics engaged in the management of abdominal pathology.

[Prevention of bronchial fistula and empyema after resection and removal of the lung].

Pulmonectomies in 231 patients and resections of a lung in 320 patients were followed by the development of bronchial fistulas in 33 patients (5.9%): after pneumonectomy--in 17 patients (7.3%) and after lobe- and bilobectomy in 16 patients (5%). Empyema of the pleura was noted in 20 patients (3.6%): in 12 patients (5.2%) and 8 patients (2.5%) correspondingly. Seventeen of 53 patients with these complications died. The use of a manual method of suturing the bronchus without a stump with the local application of fibrinogen, complex bronchological sanitation and intraoperative bronchofibroscopy (drainage of the pleural cavity after pneumonectomy with the following filling of the cavity with an antiseptic solution and formation of the selective pneumoperitoneum) allowed to decrease the incidence of bronchial fistulas in 102 patients to 2.9%, and empyema of the pleura--to 1.9%.

[Methods of excluding the liver from the general circulation for its subsequent perfusion].

Methods of exclusion of the liver from the general blood circulation for its further perfusion were studied in 316 experiments in corpses of humans and dogs. Original caval and portal canules constructed by the authors were used in 180 experimental operations in dogs weighing from 10 to 35 kg to prove the possibility of occlusion of the vena cava inferior above and below the liver to take blood from the hepatic veins and to return it into the liver after saturation with oxygen and drugs through the portal vein tributaries and hepatic artery.

[Artificial circulation method in operations on the liver].

The method of parallel and isolated artificial circulation in the liver is described on the basis of 97 experimental operations on dogs of various weights. The paper gives a brief description of the apparatus for the regional perfusion of the liver and portable oxygenator. The composition of the perfusate and main criteria of the liver perfusion adequacy are considered, including the hemodynamic shifts and disorders in the hepatic functions under the artificial circulation in the liver. The perfusion is estimated in different temperature regimens, the advantages of the hyperthermal perfusion over normal and hypothermal ones being also shown. The method of artificial circulation is recommended in vast resections of the liver, in transplantation and in the treatment of hepatic malignancies.
