[Diagnosis of pulmonary thromboembolism by transesophageal echocardiography. Report of a case].

We describe the case of a 73-year-old man, admitted after several days of moderate dyspnea, followed by sincopal episode. Transesophageal echocardiography clearly demonstrated a high resolution image indicating thromboembolus of the proximal right main pulmonary artery. The patient's clinical conditions were moderately impaired; a treatment with heparin followed by warfarin was started. At 15 and 30 days interval, TEE controls were performed, showing an incomplete but evident resolution of pulmonary thromboembolism, associated to an improvement of clinical ECG and scintigraphic parameters. Our TEE observation, in accordance with the small number of similar observations reported in literature, showed a clear direct visualization with high resolutive diagnostic possibilities for pulmonary thromboembolism; successful resolution was confirmed by repeated TEE studies.

[An application of mini-invasive surface surgery: the thyroid].

Since its introduction, minimally-invasive surgery has been applied to structures contained in natural cavities such as abdomen, thorax and articulations. At present, its application to surface zones (plastic surgery) gives good results. For this reason, we tried to examine thyroid area through a video-assisted access in a 32 years old woman presenting a nodule with a diameter of about 1 cm, localized in the left parahistmic thyroid area. This approach allowed a good vision of the operative field. In our opinion, this technique could be useful especially to formulate the histological diagnosis of small thyroid nodules for whom the standard surgical biopsy should be considered too invasive.

[Leiomyosarcoma of the duodenum: description of a clinical case].

Leiomyosarcoma of the small bowel is a rare malignant neoplasm, representing only the 8%-22% of duodenal malignancy. Diagnosis is difficult and useful is the TC scan of upper abdomen for the localization, extension and organ origin of the neoplasm. The authors report a clinical case of leiomyosarcoma of III portion of the duodenum, arose with intestinal hemorrhage, treated surgically with duodenocephalopancreatectomy, that nowadays represent the only therapeutic treatment for these tumors.

[Surgical treatment of cervico-mediastinal goiter].

Over the last decades definitions and classifications of cervico-mediastinal goiters have been proposed. According to the definition of Valdoni and Tonelli, from 1968 to 1991 237 patients were operated on for cervico-mediastinal goiter. There were 168 simple forms (141 anterior and 27 posterior) and 69 complex forms according to Borrelly's classification. We analyse and discuss the clinical presentation, the diagnostic procedures and the surgical technique in relation to post-operative complications and long term results. The mean duration of symptoms before surgery in patients with cervico-mediastinal goiter was longer than in subjects with cervical goiters. All but 8 operations were performed through a cervical incision. Two patients, both with advanced tumor, died postoperatively. Post-operative complications were: hemorrhage 0.8%, dysphonia 4.6% and transient hypoparathyroidism 2.9%. A clinical follow-up was available for 194 patients. Permanent dyspnea was observed in 1.0%, dysphonia in 4.6% and transient hypoparathyroidism in 2.9%. Tracheotomy was necessary in 5 cases. Complications were more frequent after total thyroidectomy than after partial resection (p < 0.05), after surgery for malignancy than for benign disease (p < 0.05) and in complex than in simple forms (p < 0.05). Almost all cervico-mediastinal goiters can be treated by a cervical incision. Sternotomy, when required, does not influence mobility and mortality. The lacking of an alternative treatment, the relatively high incidence of malignancy and the risk of acute airway obstruction should induce the early removal of all substernal goiters.

Malignant mesothelioma of the pleura in the Trieste-Monfalcone area, with particular regard to shipyard workers.

A series of 421 malignant pleural mesotheliomas, diagnosed in the Trieste-Monfalcone area, northeastern Italy, were reviewed. A large majority of the patients had been employed in "naval" work (shipbuilding, maritime trades, and dock work). Latency periods (time intervals between first exposure to asbestos and death), showed wide variations from one occupational category to another. Such variations were attributable, but only partly, to differences in the intensity of the exposure to asbestos. Various family cases were identified, including people with and without blood relationships. The data, obtained in the studies on Trieste-Monfalcone mesothelioma, suggest that interactions between asbestos and other factors play a considerable role in the pathogenesis of asbestos-related mesothelioma.

[Short bowel syndrome: etiologic, pathogenetic aspects and principles of treatment].

A significant problem in surgery following massive intestinal resection is the short bowel syndrome characterized by severe fluid and electrolyte loss, watery diarrhoea and malnutrition. Total parenteral nutrition and enteral nutrition are essential in the clinical course of the syndrome; their use for prolonged periods results in the gradual intestinal adaptation and greater absorptive and reservoir capacities of the intestinal remnant. Adjunctive surgery can slow rapid intestinal transit and induce growth of neo-small-bowel mucosa but is not recommended for routine use. The early results of intestinal transplantation in the treatment of short bowel syndrome are encouraging. Furthermore chronic rejection and systemic sepsis with failure of the graft must be considered and indicate that at present this procedure cannot be offered to every patient but will be a potential form of therapy in future.
