[Invasion of the chest wall in primary lung neoplasms].

The authors analyse a series of 5 patients who underwent pulmonary and parietal resection between 1990 and 1993 due to non.microcytoma bronchogenic carcinoma with invasion of the thoracic wall. The patients comprised four men and one woman aged between 45 and 69 years old. Thoracic pain was present in two patients. Pulmonary resection with extrapleural stripping was performed in two patients whereas a block resection from one to five ribs and the corresponding intercostal spaces was performed in the other three patients. The authors' approach is not to perform these operations according to rigid protocols but to adapt them according to the local status of tumour invasion. Therefore to resort to extrapleural resection when there is a free cleavage plane between parietal pleura and rib wall; resection in block of the wall where the carcinoma has infiltrated the endothoracic fascia or deeper. The authors do not report any major complications and record a postoperative mortality rate of 0%. In two cases the thoracic wall was reconstructed using a sheet of Gore-Tex which did not provoke rejection phenomena. Radiotherapy was carried out in cases with positive lymph nodes. The series presented here is too recent to provide significant data regarding survival. However, the only factor seen to influence prognosis in the five patients was the presence or otherwise of lymph node metastasis, irrespective of the histological type and operation performed. The five year survival rate of T3N0M0 patients is in fact similar to that of T2N0M0 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hepatic resection. A contribution and its analysis].

The authors outline their experience in the field of resective hepatic surgery, both with regard to benign and malignant pathologies, and analyse the results in relation to indications and techniques, but also focusing attention on the assessment of postoperative functional alterations, in order to evaluate the hepatic reserve and the organ's response to demolitive surgery. All operations were carried put in the First Division of Surgery at the Ospedale Civile, Asti, from January 1989 to September 1992. In all cases, even in major hepatectomies, a "trans-parenchymal" technique was adopted. Before surgery tests were carried out in relation to the topography of disease, its nature, associated pathologies and the functional hepatic reserve. Operative mortality was zero and morbidity was negligible, probably because rigorous selection criteria and indications for surgery were adopted. Morbidity was even restricted in the two patients suffering from HCC on cirrhosis (?) and this may probably be attributed to the limitation of resection to solely oncological purposes and their classification as Child-Pugh's stage A. The results regarding the liver response to demolitive surgery appear to be indicative and revealed a highly significant and discriminating difference between elective and emergency surgery.

[Major and minor complications in carotid surgery].

The Authors report their experience of major and minor complications in carotid surgery. They analyse the causes and emphasize that a thorough preoperative study and a quick surgical technique are very important in reducing the rate of complications in this essentially preventive form of surgery.

[Surgical treatment of liver metastases of colorectal carcinoma. Our experience and review of the literature].

The authors describe their personal experience of the surgical treatment of hepatic MTS caused by colon-rectum ca. Following a review of the literature, including therapeutic protocols which do not always agreed, the problems inherent to the number, site, size and appearance of MTS themselves are discussed. Different approaches are compared in an attempt to clarify this pathology about which still very little is known. There is often uncertainty regarding the cases which should be treated surgically, and there is certainly a need for a greater number of case studies so as to avoid relying on the sensitivity and experience of the individual surgeon.

[Parietal damage in intestinal infarction. Clinical and anatomo-pathological considerations].

The physiopathology of parietal damage due to acute ischaemia is reviewed on the basis of a personal series of more than 70 cases. The reported data (not particularly abundant) is examined and an attempt made to draw conclusions that, free from mere theoretical and abstract value, may materially help the surgeon in his by no means easy decision to revascularize or resect an intestinal segment.

[Reimplantation of the inferior mesenteric artery during surgery of abdominal aortic aneurysm. Current trends].

After a review of world literature and on the basis of personal experience, the problem of ischaemic colitis following abdominal aortic aneurysmectomy is examined. After remarks on the aetiopathogenesis and clinical picture of the condition the paper stresses the need for early detection of patients at high risk, to prevent a clinical picture that is insidious but serious and tends to develop rapidly. The use of preoperative angiography to study the SMA and IMA as well as intraoperative stump-pressure measurement is considered essential. The paper concludes that ischaemic colitis following abdominal aortic reconstruction can be avoided in a large percentage of cases by IMA implantation on the Dacron prosthesis, a surgical technique that is easy and not time-consuming.

[Surgical therapy of the kinking of the internal carotid artery. Indications and limitations].

Surgical treatment of a case of symptomatic kinking of the internal carotid suggested a review of the problem on the basis of the national and international literature. Opinions are not only extremely distant but not infrequently antithetical. In such a heterogeneous subjects that is often difficult to interpret, the most interesting approaches are examined in the light of new experimental and clinical findings.

Urinary sodium levels related to jaundice duration in the assessment of postoperative risk of hepatorenal syndrome in elderly patients undergoing surgery for biliary obstruction.

The early diagnosis of hepatorenal syndrome (HRS) is based chiefly on biochemical alterations and in particular, the relationship between urinary sodium levels and duration of jaundice seems to offer the most reliable prognostic index. Urinary sodium levels were determined in 32 elderly patients, who underwent surgery for benign or malignant biliary obstruction, without, major organ resection; in this group 4 patients died of HRS (12.5 per cent). The diagnostic accuracy of the method reached 97 per cent.
