[Videothorascopic surgery--initial experience].

Practical experience with the miniinvasive laparoscopic technique in abdominal surgery logically led to extension of this method to thoracic surgery. Video-assisted thoracoscopic operations hold their place in the treatment of spontaneous pneumothorax, pleural syndrome, benign tumours of the thoracic wall etc. A curative solution of malignant diseases by this route is so far controversial and is reserved only for specially defined cases. Experience from the authors' department is based on nine-month use of a thoracoscopic apparatus. The authors operated a total of 21 patients thoracoscopically, incl. pneumothorax 6x, fluidothorax 10x and tumourous disease of the lungs or mediastinum 5x. The use of thoracoscopy is controversial in metastases of the lungs and in thymectomy. With regard to the authors are against thoracoscopic indications in the latter conditions contemporary technical possibilities.

[Stab and gunshot thoracoabdominal injuries].

The authors give an account of their experience with the treatment of punctures and gunshot injuries of the chest and abdomen in 43 patients hospitalized at the Surgical Clinic of the Third Medical Faculty, Charles University Prague 10 between 1989 and 1992. Injuries of the chest were recorded 15 times, abdominal injuries in 25 patients and concurrent injuries of the chest and abdomen in three patients. To ensure treatment of penetrating injuries the authors present an algorithm which comprises differentiated care as well as some non-interventional diagnostic methods (ultrasonography, computed tomography). Based on analysis of their own results and data in the literature, the authors recommend in casualties with penetrating chest injuries and abdominal injuries early indicated surgical revision which alone ensures adequate treatment with minimal diagnostic errors. They also draw attention to the necessity to ensure effective first aid and rapid transport of casualties to prevent the development of irreversible changes as a result of haemorrhage, as observed in a single patient who died after a piercing heart injury.

[Diagnostic and therapeutic approaches to spontaneous pneumothorax].

Based on a retrospective study of 33 patients with spontaneous pneumothorax, the authors present their experience with the diagnostic and therapeutic procedure. In the majority of patients treatment was started by active suction drainage of the chest. After re-expansion of the lung another X-ray examination was made, incl. computed tomography of the chest, and endoscopic examination (bronchoscopy, thoracoscopy). On account of a relapse of pneumothorax in three patients thoracoscopy was performed and in seven patients thoracotomy. The operated patients recovered and are without signs of relapse of pneumothorax.

[Use of Nutramin VLI Spofa for parenteral nutrition in the early post-injury period in polytrauma].

The solution of branched-chain amino acids of gradually increasing concertration ranging from 22.7 to 43 per cent was administered to 15 patients with polytrauma as part of parenteral nutrition. Parenteral nutrition was started with during 24 hours after the trauma. The effect of parenteral nutrition was objectified by a twenty-four hour balance of water, ions, energy and nitrogen and by a follow-up of kinetics of amino acids in the plasma. It was found out that the increase of the share of branched-chain amino acids up to 43 per cent resulted in a pharmacodynamically efficient level of valine. There occurred gradual adjustment both of the levels of other aminoacids in the plasma and other metabolic changes including the restoration of proteosynthesis.

[Parenteral nutrition using branched-chain amino acids (Nutramin VLI Spofa) in the early postoperative period in patients with intra-abdominal inflammatory diseases].

In 19 patients with intraabdominal septic conditions hospitalized at the Surgical Clinic of the Medical Faculty of Hygiene, Charles University, Prague 10 in 1987-1988, the effect of the gradually increasing ratio of branched amino acids administered in parenteral nutrition was investigated. The administration of branched amino acids (Nutramin VLI Spofa) was started already on the first day after operation. By increasing the ratio to 43% of branched amino acids gradual normalization of metabolic changes occurred, incl. normalization of free amino acid plasma levels.
