A case of intrapericardial diaphragmatic hernia with stomach and colon migration is reported. Stress is laid on the problem of early diagnosis, as the condition is usually asymptomatic: the scpra-umbilical median laparotomy approach route is proposed.

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.

BACKGROUND: After the liver, the lungs represent the most frequent site of metastasis from primary tumours. Surgical treatment of lung secondary neoplasms leads to a significant improvement in survival. METHODS: Between 1960-1997, 178 patients with lung metastases underwent surgery at the Thoracic Surgery Department of Turin University in a total of 193 operations. A retrospective study was made in order to identify the prognostic factors which influenced final survival in this population. RESULTS: Overall survival was 47% after 2 years and 20% after five years. Prognosis was not influenced by the size of metastases, the type of surgery, adjuvant therapy and the number of operations on the same patient. On the other hand, useful prognostic factors were found to be the histological type of the primary tumour, the original site of the neoplasm, the number of metastases and, above all, the disease-free interval (DFI). CONCLUSIONS: Lung metastasectomy is an important therapeutic aid in selected patients, whereas the preoperative evaluation of the above prognostic factors enables a reasonably precise prognosis to be made in most patients.
