Endoscopic laser treatment of benign tracheal stenoses.

We present the technique and results of endoscopic neodymium-yttrium aluminum garnet laser treatment of benign tracheal stenoses. This therapy was used in 15 patients with tracheal stenoses. Benign tracheal granulomas were caused by prolonged tracheal intubation in eight patients, permanent maintenance of tracheostomy tube in five patients, and nonspecific inflammatory process of the trachea in two patients. The clinical picture was dominated by dyspnea and stridor. The achievement of normal tracheal patency required several laser therapy sessions, repeated at 5- to 7-day intervals. In 30% of patients additional laser vaporization was required as well. The immediate and short-term results were encouraging; in all cases the normal tracheal lumen was restored, resulting in alleviation of patients' symptoms.

[Orthotopic liver transplantation in a patient with primary biliary cirrhosis].

In December 1994 an orthotopic liver transplantation was performed in a 46-year old female patient with liver failure due to primary biliary cirrhosis. The patient was discharged on the 31-st postoperative day. The graft was obtained at the multi-organ harvesting. The results of the donor's biochemical tests and the histological estimation of the graft tissue allowed to prognose a successful postoperative course.

[Endoscopic treatment of iatrogenic tracheal stenosis by laser Nd:YAG].

The authors present the technique and results of endoscopic Nd:YAG laser treatment of inflammatory tracheal stenoses. This kind of therapy was employed in 10 patients with tracheal stenosis, resulting from long-term nastotracheal intubation (6 cases), tracheostomy tube after radical laryngectomy (3 cases) and tracheal trauma. The laser fiber was introduced into trachea by the operative channel of a flexible bronchoscope and vaporization of obstructing tissues carried out using contact method in continuous mode of light emission (power 7-20 Watts). The achievement of normal tracheal patency usually required several laser therapy sessions (3-5), repeated in 3-5 days intervals. The short-term results are encouraging: in all cases the normal tracheal was lumen was restored, resulting in alleviation of patients' symptoms. In 3 cases a recurrent tracheal stenosis, requiring additional laser treatment was observed.

Preoperative concurrent chemotherapy and radiotherapy for local-regional and advanced squamous cell carcinoma of the thoracic oesophagus: preliminary results of a pilot study.

Preliminary experience based on the results of a pilot study on preoperative concurrent continuous i.v. infusion chemotherapy and radiotherapy for squamous cell carcinoma of the oesophagus in eight consecutive patients is presented. Chemotherapy consisted of 5-fluorouracil and cisplatin. Radiotherapy (Co-60) was delivered to a total dose of 3000 cGy. Clinical tolerance was good in four of eight patients, but poor in the remaining four, including three septic deaths. Oesophagectomy was performed in five patients with no postoperative deaths. Postoperative complications (Horner syndrome, hydrothorax, abdominal wound dehiscence) were observed in three cases. The response was categorized as complete (CR), partial (PR) or stable disease (SD), based on a comparison of the initial and immediate preoperative imaging studies and on the presence of tumour degeneration and/or necrosis in pathological examination of operative specimens. CR was observed in 1/8 patients, PR in 4/8 and SD in 3/8. Concurrent preoperative chemo- and radiotherapy may be effective as a neo-adjuvant or remission-inducing modality in the combined treatment of oesophageal carcinoma, however, it may also lead to fatal complications.

Cardiac chambers and their walls in cardiomyopathies as evaluated with CT.

Thirty-two patients with cardiomyopathy, 25 with hypertrophic and 7 with dilated form were examined by cardiac catheterisation, left ventriculography, selective coronary angiography and ungated cardiac computed tomography. Diffuse hypertrophy, localized hypertrophy and dilated cardiomyopathy were diagnosed and assessed quantitatively based on CT linear, surface and volumetric parameters of cardiac morphology. Absolute septal thickness and left ventricular mass measured in CT image are the most discriminative attributes.

Case report. Renal oncocytoma.

In a case of renal oncocytic adenoma, a "spoke-wheel" pattern of pathological vessels was observed at arteriography of the highly vascular tumor. Computed tomograpy revealed a solid mass with attenuation value significantly higher than that of the normal renal tissue.
