CO2 laser knife was applied in 18 thoracic operations. The laser knife can be used for the sterile and ablastic cutting of skin, soft parts, ribs, sternum, bronchi and lung parenchyma. By its use intraoperative bleeding is substantially diminished.

Two operations each were performed on two children for malignant mediastinal tumours which had been inoperable, in the first place. The tumours not removable at the first attempt were reduced in size by radiotherapy and cytostatics and could then be removed in a second session.
In the post decade seven patients have been operated for pulmonary arteriovenous fistula at the 3rd Department of Surgery of the Semmelweis University Medical School, Budapest. Three of the patients were adults, the others being children and adolescents. Fistules were localized in the left lower lobe in four cases, and in the right upper lobe in three cases. Two of the patients displayed bilateral fistules. The type of the operation was lobectomy in six cases and enucleation in one case. The symptoms, the diagnostic and surgical methods and the results obtained are discussed.
Operations were performed on 20 children for Pectus excavatum in five years. 'Turn over' of the sternum was chosen as surgical approach. About five years have passed from those operations, and results still are better than those obtained from earlier methods based on stabilisation of the sternum.

Of the 1029 thoracic surgeries carried out since 1950 at the Second and later at the Third Surgical, University Clinic in Budapest on infants, children, and adolescents 215 were cases to correct some developmental anomaly. Pulmonary cysts--both single and multiple--represent the largest number, followed by lung-sequestration, lobar emphysema, and bronchial arterioma. To assess the late results, 106 ex-patients were invited to the clinic for check-up. They had beed operated at least 10 years before; the longest follow-up time was 23 years. Eighty-nine (83.9%) of the 106 patients appeared at the clinic. One pulmonectomized for a polycystic lung (0.9%) died in the meantime; 16 were not available. The 89 patients were submitted to a clinical examination, including radiological examination, spirometry, and ECG. With one exception (Kartagener syndrome), they were found in good condition and free of complaints. They carried on some studies or worked in different jobs. There were no relapses. They developed very satisfactorily no matter whether their operations took place in infancy, childhood or adolescence. The surgical intervention did not affect growth and development. Congenital pulmonary malformations and disorders should be treated by surgery, and the long-term results are better if the operation is performed at the proper time.

The etiology and treatment of acute pancreatitis are discussed. The two main principles are conservative and surgical treatment. Biliary decompression was chosen as an elective method in the surgical treatment of acute pancreatitis, if signs of bile stasis and tension of the common bile duct could be seen. Peritoneal or peripancreatic dialysis were also applied. Five patients were treated in this way; according to literature and our experience it is a good, short and curative intervention for the treatment of acute pancreatitis.
The authors have retrospectively reviewed 390 autopsy reports from their surgical clinic, to establish the frequency of chronic and acute lung complications in surgical patients. The retrospective analysis revealed that pneumonia was the most frequent acute pulmonary complication among patients who died in the surgical department. In postoperative cases, pneumonia contributed to or was responsible for 65% of all deaths.
