Background: To evaluate the possible role and the effectiveness of videothoracoscopy (VATS) in the treatment of pleural empyema., Methods: Personal experience on 40 cases of pleural empyema treated by (VATS) during 5 years is reported. The underlying diseases were: pneumonia (32), pneumothorax (3), tuberculosis (2), abdominal diseases (2) and lung cancer (1). Before VATS at least one thoracentesis was performed to evaluate the characteristic of the pleural fluid., Results: Due to complications related to thick pleural adhesions, in one case (2.5%) the procedure was converted to open surgery, while in the remaining 39 cases VATS was able to achieve a complete cleaning of the pleural space with re-expansion of the pulmonary parenchyma. The improvement of the clinical symptoms were observed after a mean period of 3.5 days (range: 1-12 days). Chest tube was removed in a mean period of 4.8 days (range: 3-11 days); five patients had prolonged air leak from 6 to 10 days after surgery., Conclusions: In conclusion we are of the opinion that VATS has to be considered a very important mean for the treatment of pleural empyema; its use in the fibrinopurulent phase of the disease should give very good results, while in the following phase its indications are controversial.

The authors report their experience about 15 patients surgically treated for chronic large pericardial effusion; in 12 cases the etiology was malignant neoplasm, while in the other 3 cases was inflammatory disease. In 4 patients a simple subxiphoid pericardial drainage was carried out, while in the other cases a pericardial window was performed. These cases were managed using an anterior left thoracotomy in 8 patients and a videothoracoscopy in 3. The authors conclude that pericardial window with videothoracoscopic approach is the preferable procedure, but it cannot be used in every case because a lot of patients have seriously compromised conditions and the use of this technique can be hazardous.

The authors present 2 cases of pulmonary lower lobectomy (right and left) using video-assisted modality. The I patient had a stage I NSCLC and the II had a metastasis from rectal carcinoma. The operation was performed using the modern videoendoscopic means introduced into the thoracic cavity thorough three ports and an anterior 4 cm mini-thoracotomy. The patients had an uneventful postoperative course and no pain or trouble breathing were observed. In conclusion the authors are of the opinion that performing lower pulmonary lobectomy, video-assisted technique is feasible and reliable; in very selected cases it should become the modality of choice.

The authors report their experience of 14 cases of hepatic trauma that underwent surgical treatment. During the period 1987-1990, 42 patients were admitted with diagnosis of hepatic injuries to the surgical department of Ravenna Hospital. 28 of the 42 patients were subjected to repeated abdominal echography and didn't undergo surgical treatment. The authors consider the importance of the abdominal echography whether of the surgical treatment or nonoperative management. Prognosis is always serious, and it is influenced by three factors: the kind of trauma, the concomitant lesions and the general conditions of the patient. The authors, in conclusion, report the per cent of survive and of complications that they have found.

The authors report their experience of transthoracic needle biopsy of the lung based on 68 consecutive cases from 1984 to 1990. In 55 cases significant data has been found: in 44 cases the diagnosis was exact, instead in other 11 cases it was only indicative. The overall complications were 11.7% and in particular were as follow: pneumothorax in 5 cases, hemoptysis in 2 cases and a temporary Horner syndrome in one case. The authors conclude by confirming the utility of transthoracic needle biopsy of intrathoracic tumors in which there is not other way to obtain a diagnosis. This technique is reliable and its complications can be disregarded.

Following an analysis of current treatment strategies for spontaneous pneumothorax and their surrounding controversies, the paper reports the Authors' personal experience. From 1 January 1984 to 31 December 1989 a total of 76 cases of spontaneous pneumothorax were treated, of which 3 were bilateral. The M:F ratio was 9:1 and the age of patients ranged between 16 and 77 years (mean age 39.2); 22 cases were relapses (27.8%). Conservative therapy was used in 12 cases (15.1%); pleural drainage was introduced in 54 cases (68.3%) for a mean of 7.5 days. Fourteen thoracotomies were performed in 13 patients (10.4%): bullectomy was performed 10 times with stapler, whereas pleurodesis was obtained in 9 cases using pleural abrasion and in 5 cases using apical pleurectomy plus pleural abrasion. Axillary thoracotomy at the 5th space was most commonly used. No major complications were observed during the postoperative period and, in spite of the minimum follow-up of 3 months, no cases of relapse were observed in operated patients.

In pigs with acute hepatic failure, induced by one stage hepatic devascularization, plasma amino acids pattern changes markedly. Besides an increase in aromatic amino acid and a decrease in branched chain amino acid levels, urea cycle amino acids levels change. The content of ornithine and citrulline is enhanced, while arginine level drops down dramatically within six hours after surgery. These observations suggest that an enrichment of the arginine content of amino acids solutions recently proposed for the therapy of the hepatic encephalopathy might be useful.

After having discussed the direct and indirect methods to control the patency of porto-systemic anastomoses, the Authors report on their series of 42 cases (28 side-to-side porto-cava shunts, 6 end-to-side porto-cava shunts, 6 spleno-renal shunts, 2 mesenterico-cava shunts) where the postop. control was carried out with portography, hepatic superselective arteriography in 29 cases, transcaval catheterism of the anastomosis in 6 patients, and pre-op., and post-op. echotomography in 15 cases. Portography revealed 39 cases of patent anastomosis and thrombotic occlusion in 3 cases. The typical sign of shunt patency is the visualisation of the inferior V.C. and the less frequent disappearance of right gastric reflux. Furthermore the investigations consented the evaluation of altered post-shunt hepato-portal flow: side-to-side porto-cava shunt (25 patent anastomoses) revealed a complete deviation of portal glow towards the I.V.C. and in 15 cases there was inverted portal flow; portography after splenorenal shunt (5 cases of patent anastomosis) showed a preserved hepatopetal portal flow only in early controls (7 days) while in all long term controls it was hepatofugal. In 13 cases the morphology of the hepatic arterial system was compared before and after surgery; in 12 cases the hepatic artery was larger and its intrahepatic branches more tortuous after surgery Ultrasonography revealed only 8 patent shunts out of 15 examined since the amount of gas in the bowel rendered the exam technically insufficient.

Personal experience with 75 consecutive cases of terminolaterale oesophagojejunal anastomosis by EEA Stapler is reported. A total of 6 intraoperative technical problems were encountered (8%) and consisted either of incomplete suturing of the anastomosis or stapling of the jejunal wall. Postoperative radiology revealed 5 dehiscences (6.6%) and 1 stenosis (1.33%). One patient with dehiscence died (1.33%) of septic complications. One dehiscence of the afferent jejunal stump and minor pleuropulmonary complications were observed in 3 cases. After a brief review of the literature, it is concluded that oesophagojejunal anastomosis by EEA Stapler produces a low incidence of postoperative complications such as the dehiscence, stenosis or bleeding.

The authors report their experience about splenic breakages in the blunt abdominal traumatology. Through the analysis of different parameters (type of accident, other associated lesions, heart frequency, hematocrit, paracentesis, direct radiological inspection of abdomen, gap of time between hospitalization and operation) they try to frame the blunt traumata of abdomen in four differential and orientative classes. As a conclusion; they assert the diagnosis of splenic breakage can be placed in any hospitals, with no need for sophisticated investigations, but following clinico-laboratorial criteria.
