Preoperative integrated neo-adjuvant radio-chemotherapy was performed in 8 patients suffering from NSCLC bronchial carcinoma at stages IIIA-IIIB (N3 mediastinal). After treatment, 7 patients underwent apparently radical pulmonary exeresis, whereas the patient with adenocarcinoma (T2 N2 M0) was not operated due to the recurrence of disease following supraclavicular lymph node metastasis. Preoperative radio-chemotherapy allows the sub-staging of the disease and the insertion of these patients into the operating programme.
A case of jejunum-ileum multiple diverticulosis observed during a cholecystectomy due to cholelithiasis, is reported. Stress is laid on this unusual localization of diverticulosis in the small intestine. The clinical picture can be silent or present an acute or chronic symptomatology and radical surgical treatment can performed or not. When the disease involves all the intestine, without presenting serious inflammatory phenomena and without clinical symptoms (as in the case observed), medical and not surgical treatment can be envisaged.
After some general observations on liver echinococcosis (epidemiology, liver topographic anatomy, diagnostics), various surgical techniques proposed for the treatment of this disease are described. Case series observed from 1967 to 1978 and the technique of choice, cystotomy with partial cysto-resection, are presented. The favourable results obtained are underlined.
A series of malignant cancers of the oesophagus operated in the period 1968-1978 is reported. The importance of preoperative denutrition is considered and the various nutritional techniques are outlined, with a note on their advantages and defects. Right intrathoracic oesophagogastroplasty carried out in malignant cancers of the middle third of the oesophagus is particularly discussed. This surgical technique is held to be preferable to intestinal transpositions in substitution of the oesophagus, and the results obtained in this series support the opinion.

The conclusions contained in recent and past literature regarding the heterotopic pancreas are reviewed. A case of accessory pancreas located in the stomach, whose clinical, radiological and endoscopic aspects simulated a carcinomatous process, is reported. The case is studied anatomo-pathologically and important aspects, including surgical, noted.
1) Haemobilia must be kept in mind as a cause of gastrointestinal haemorrage. 2) The presence of an hepatic artery aneurysm gives a peculiar triad of symptoms: abdominal pain, gastrointestinal haemorrage and jaundice. 3) Selective angiography is the elective diagnostic aid. 4) The diagnosis may be difficult also at operation, because the aneurysms can be very small. 5) The most used surgical treatment are ligation of the hepatic artery, the excision of aneurism, the endoaneurysmorrhaphy or the end-to-end anastomosis.
Liposarcoma is one of the more common tumours of the soft retroperitoneal tissues. It usually occurs in aged subjects and displays a marked contrast between its malignant histological picture and its protracted, poorly symptomatic clinical picture. Eventually, compression or invasion of nearby organs appears, whereas the patient's general condition is not affected. Two personal cases are described.
A case of bile duct obstruction due to Fasciola hepatica is presented. The evolution, aetiopathogenesis, symptomatology, diagnosis and therapy of this rare syndrome are then discribed.
A case of gastric leiomyosarcoma (primary maliganant mesenchymal neoplasia of non-lymphoblastic origin) personally observed, is presented. The pathological anatomy, aetiopathogensis, symptomatology and diagnosis of this disease are described as well as the surgical treatment of the case.
True and pseudo-cysts of the pancreas are described and their aetiology, pathology, laboratory tests, radiological examination, differential diagnosis, symptomatology and surgical management are illustrated. A series of 22 cases of pancreatic cyst is presented. Surgical management consisted of 14 cystogastrostomies, 3 cystoduodenostomies, 2 resections of the tail of the pancreas, 1 internal drainage between the fistular segment of the gland and the gastric cavity, and 2 external drainages with a Pezzer tube. It is felt that internal drainage is the operation of choice. Of the surgical techniques available, a preference is expressed for cystogastrostomy and cystoduodenostomy.
From 1980 to 1990, 1505 patients underwent thoracotomy as definitive treatment for non small cell lung cancer. Computed tomography (CT) of the chest has been used routinely since 1984 for assessment of mediastinal lymph node involvement. A total of 235 cervical mediastinoscopies and 71 anterior parasternal mediastinotomies were performed on the same patient population as preoperative staging when CT scan demonstrated mediastinal lymph nodes larger than 1 cm. Radical resections showed a constant increase in number from 70.1% in the period 1980-84 to 82.7% in the period 1985-90. Exploratory thoracotomies and thoracotomies with residual tumor showed a parallel reduction: 14.5% in 1980-84 to 7.4% in 1985-90 for the former, 15.4% in 1980-84 to 9.8% in 1985-90 for the latter. The percentage of N2 disease to the total number of thoracotomies decreased from 23.6% in 1980-81 to 11.2% in 1989-90. We conclude that a selective use of cervical mediastinoscopy and anterior parasternal mediastinotomy, based upon the results of CT scan, may have contributed to reduce the number of exploratory thoracotomies and thoracotomies with residual tumor.
In the ten-year period 1982 to 1991, 94 patients underwent pleural abrasion as definite treatment for spontaneous pneumothorax. Surgical indications included: 1) third recurrence of homolateral pneumothorax, 2) second recurrence of homolateral pneumothorax in the presence of alternating pneumothorax, and 3) persistent air leak with incomplete lung re-expansion in the presence of spontaneous pneumothorax treated with pleural drainage for more than 10 days. No deaths were observed in the present series. Post-operative complications were minimal and all reversible, including two cases of pleural effusion, one case of hemothorax, and one case of Horner's syndrome. Eighty cases were followed up from 7 to 91 months. No recurrences occurred during the follow-up period. Clinical, radiological and functional results appear satisfactory. Pleural abrasion seems to represent a valid surgical option in the treatment of recurrent or persistent spontaneous pneumothorax.
The paper reports the authors' ten-year experience of the surgical treatment of cancer of the esophagus. A total of 625 patients with esophageal carcinoma were observed during the period 1980-89 of whom 490 were admitted to hospital and, of the latter, 172 (35.1%) were operated with a sectile rate of 86% (148 patients). Data from this period were analysed both retrospectively and prospectively using a computerised system. There were 105 radical operations (70.9%) and 43 palliative operations (29.1%). The 3-year actuarial survival rate was 21.7% and the difference between radical and palliative resections was at the limit of significance (p less than 0.1).
