[Efficacy of continuous intercostal analgesia versus epidural analgesia on post-thoracotomy pain].

The authors compare the efficacy of epidural morphine analgesia with continuous intercostal extrapleural block using bupivacaine 0.5% after thoracotomy. They affirm that antalgic treatment in thoracotomised patients is the most important factor in preventing the onset of major complications that may negatively influence the results of surgery.

[A carcinoid with cecal localization. Apropos a case].

An observed case of carcinoid tumor of the large-bowel in a 68-year-old woman leads to an analysis of the clinical-diagnostic and therapeutic aspects of this rare gastrointestinal tumour. Carcinoid tumour represents 0.8-1.

[CT-guided FNA in the diagnosis of lung opacities. Our experience].

Between January 1989 and December 1994 we accomplished 130 CT-guided transthoracic fine needle aspirations (FNA) in 120 patients. Ten patients underwent a second FNA because of the negativity and doubts of the first. Diagnosis was targeted in 114 (95%) patients and 89% showed cytological evidence of malignancy.

[Spigelian hernia: apropos of two cases].

Two observed cases of spigelian hernias in 54 years and 62 years old men leads to an analysis of the diagnostic clinical and therapeutic aspects of this rare abdominal pathology. It represents 1-2% of all abdominal hernias and can occur anywhere along the semicircular line of Douglas, but in 90% of cases its most frequent localization is from the level of the umbilicus to the inguinal area. Diagnosis can be difficult because of non-specificity of symptoms.

[Pleuro-pericardial cysts. Case reports and clinical-diagnostic as well as therapeutic considerations].

Three patients with pleuropericardial cysts are reported. The authors accoding to what exists in literature confirm the congenital origin of this relatively rare pathology. It is benign and rapresents 6-19% of all mediastinal neoplasms.

[Stomach leiomyosarcoma. Clinico-diagnostic considerations and therapeutic criteria].

An observed case of leiomyosarcoma of the stomach in a 67 year old man leads to an analysis of the diagnostic, clinical and therapeutical aspects of this myoid tumour in the digestive tract representing 50-60% of cases. Symptoms are aspecific and gastric bleeding is the most common sign (50%). leiomyosarcoma always presents considerable problems of diagnosis and represents the most important among the various examined diagnostic investigations but it is maintained that surgery many times plays a primary role in the diagnosis of this tumour.

[Thoracic neurinoma: a case of a giant neurinoma].

Having observed 6 cases of benign tumours deriving from nerve sheaths, one of which was of exceptional size (19 x 11 x 10 cm), with an endothoracic localization over the past 5 years, the Authors analyse the etiopathogenetic problems, anatomo-clinical symptoms and the possible methods of treating these endothoracic tumours. Neurinomas represent between 60 and 70% of mediastinal neurogenic tumours which account for 20% of all cancers of the mediastinum. Their typical localization is the posterior mediastinum, along the paravertebral grooves, and the dimensions of these tumours vary between 3 and 8 cm, although on rare occasions they reach 15 cm.

[Intrathoracic hemangiopericytoma localized in the mediastinum].

The paper reports a case of intrathoracic hemangiopericytoma localised in mediastinum which was brought to the authors attention and treated surgically. Having analysed the tumour's macro- and microscopic histological and biological features and the most suitable methods of diagnosis, the authors stress that, in line with international literature, radical surgery extended to the surrounding tissues is the elective surgical treatment for hemangiopericytoma in a mediastinal site.

[Hamartochondroma of the lung. Apropos 11 cases].

The authors take the opportunity of 11 cases of pulmonary hamartomas observed during the last 10 years, to specify the clinical and diagnostic problems and the therapeutic possibilities of this rare pulmonary neoplasm. The hamartochondroma is found mainly in the male sex, between the age of the fifth and sixth decades of life; the size of the neoplasm varies from 2 to 4 cm, rarely exceeding 10 cm. In 8 cases the operation was the simple enucleation of the hamartochondroma or its removal by atypical resection: in only one case, become of the conspicuous dimensions of the neoplasm, was it necessary to perform a typical lobectomy.
