[Insular tumours of the pancreas (author's transl)].

The use of immunohistochemistry and radioimmunological assay of the pancreatic polypeptides in the plasma has contributed substantial advances to the histophysiopathology and preoperative diagnosis of tumours of the endocrine pancreas and the related functional syndromes. Consequently, in addition to furthering knowledge on clinical pictures already known for some time, it has been possible to define new categories of the disease which were previously misunderstood or confused with others. The physiopathology and diagnostic methodology (clinical, biohumoral and instrumental) of each main known syndrome (insulinoma, Zollinger-Ellison Syndrome, Verner-Morrison disease and glucagonoma) are described in detail; there are notes on hormonal syndromes that are not fully known and which constitute a field of research in evolution (pluriendocrine and carcinoid syndromes, polypeptidoma, somatostatinoma, nesidioblastosis). The problems of preoperative preparation, intraoperative diagnostic tactics and surgical technique are illustrated. Lastly the possibilities of alternative therapeutic treatment are outlined.

[Palliative treatment of esophageal cancer].

The AA. describe the indications, the technique and the complications of application of oesophageal endoprosthesis (Celestin or Haring) for palliative treatment of oesophageal cancer and they value the results of 34 applications of these prosthesis that were executed about Surgical Clinic in Verona with satisfactory results during the period 1974-77. They show the improvement of survival conditions in these patients, the rareness of complications, the absence of absolute contra-indications.

[A case of choleretroperitoneum (clinical study)].

The AA. report one case of "choleretroperitoneum". They discuss the techniques of diagnosis that they have used, outlining the importance of A.C.T. (Axial Computerizing Tomography) and of Transduodenoscopic Cliolangiography, that have permitted a preoperative diagnosis and an exact surgical treatment of this case.

[Exocrine pancreas cancers: our experience (author's transl)].

The AA. report 136 cases of exocrine pancreas carcinomata that they have observed in 8 years in Surgical Hospital in Verona and they tackle diagnostic problems and surgical therapy. They confirmed the utility for the diagnosis of echotomography (ECO), computerizing axial tomography (T.A.C.), retrograde-endoscopic-cholangio-pancreatography (PTC). Considering the survival, at a distance of the cases that had an operation and life quality, the AA. incline, if possible, for a destroying surgical operation.

[Major hepatic resections for angioma].

6 cases of solitary angioma of the liver, treated with major hepatic resections, are presented (2 rt hemihepatectomies - 2 lt hemihepatectomies - 1 lt lateral sect. and 1 segmentectomy of the VIth). Their anatomopathological definition (solitary angioma, multiple angiomas, hemangiomatosis) is discussed in relation to the various therapeutic possibilities. From the diagnostic standpoint, an outstanding part is played by angiography. In addition to demonstrating the presence of hepatic mass, C.A.T. can, according to their experience, also allow diagnosis of quality on the basis of demonstration of vascular lacunae. It is considered that the treatment of choice of for solitary angiomas is surgery, which must be performed by skilled surgeons and consist in hepatic resections conduced by typical route. This is especially true for the giant forms, owing to their particular tendency to growth and spontaneous rupture. For small angiomas it is considered better in principle to remove them, generally by small cuneiform resections, unless they are situated in sites difficult to attack surgically and with high risk. In this case frequent check-up is necessary since, although they are sometimes found to be stationary and even in exceptional cases regressive, personal experience (2 cases) has demonstrated a tendency to expansion.

[Major hepatic resections for carcinoma of the biliary tract].

The Authors report their experience regarding two primitive tumours of the confluent and one tumour of the gall bladder involving the biliary confluent, all treated by major hepatic demolitions--one left hemihepatectomy and two extended right hemihepatectomies--with removal of the biliary tree en bloc and appropriate reconstruction. These highly demolitionary operations were performed with the aim of achieving greater radicality. The indications for such type of operation, dictated by notions of tumoral biology and reasons of surgical technique, are discussed. The Authors make a comparison of their experience with the data obtained from literature, which up to now reports only twenty-two; no statistical judgment on the effectiveness of the method is therefore possible, even if the results obtained and the theoretical presuppositions would seem to confirm its validity.

[Cystadenocarcinoma of the pancreas. Considerations on a clinical case].

A case of pancreatic cystoadenocarcinoma treated surgically four years earlier as a pancreatic pseudocyst is reported. The problems of differential diagnosis between cystic tumours (cystoadenoma and cystoadenocarcinoma) and the more common pseudocystic lesions are analysed. Stress is laid on the importance of correct intra-operative diagnosis, mainly based on multiple biopsy of the cyst wall, and the need for radical exeresis.

[Cavitary carcinomas of the lung with a pseudocystic aspect. Description of 2 clinical cases].

In this paper the Authors describe two cases of carcinoma of the lung with cavitary aspects that came under their observation. There are various hypotheses on the formation of such cavities: it is possible that the neoplastic cells may have a growth trend in a centrifugal direction, or that the cavity is due to a necroic-colliquaive process of the mass itself or to extensive phenomena of autophagism. In other cases the neoplastic cells carpet already existing air cysts, giving the appearance of thin wall cavitation. It is precisely this type of cavitation that poses problems of differential diagnosis. In fact, when other instrumental investigations such as bronchoscopy or needle biopsy, always combined with cytology of the sputum, are not decisive, a relatively certain diagnosis can be obtained only by observing the evolution of the picture for some time, as was the case in the patients referred to above.

The cancer of the papilla of Vater. Diagnosis, treatment and long term results.

Survey of 18 cases of cancer in the Papilla of Vater, which were observed during the years between 1971 and 1979 at the Surgical Clinic of Padua University - Seat of Verona - with particular regard to the diagnostic means and their reliability. The histological investigations gave the following results: All lesions were found to be adenocarcinomas; 6 cases well differentiated, 4 cases fairly well differentiated, 2 cases little differentiated, 3 cases indifferentiated. The following operations were carried out: 15 Duodenopancreatectomies, 3 Internal derivations of the biliary flow, one of which associated with gastroenteroanastomy. Of all the patients who underwent to the radical operation, 1 survived 3 years after the operation, and then was lost to the follow-up, 2 were surviving 19 months after the operation, 2 were surviving 12 months after the operation, 1 was surviving 10 months after the operation, 1 died 18 months after the operation, 7 died between the 2nd and the 12th month after the operation, 1 died in the postoperative period. Of those patients who underwent the palliative operation, none survived longer than one year.

[Alteratiions of calcium and phosphorus metabolism in patients treated with duodenoencephalopancreatectomy].

In a followup study of 14 patients treated by duodeno-cephalo-pancreatectomy at least one year before, the authors detected radiological evidence of bone tissue reshuffling in 64 per cent of the cases. Of these, 70 per cent showed high serum alkaline phosphatase content not attributable to cholestasis, liver metastasis, or specific bone disease. The authors call attention to the significance of this biochemical parameter for diagnostic purposes and therapeutic guidance.

[A case of duodenal schwannoma (clinical study)].

Taking a case of duodenal schwannoma, that they had observed, as a starting point, on the base of their experience and the data of literature, the authors discuss the epidemiological, of classification and anatomo-pathological aspects of this rare neoplastic form. They particularly outline the clinical aspect, the diagnostic pre-operating iter and the correct and radical surgical behaviour that must be practiced during laparatomy.

[The problems of surgical tactics in the treatment of pancreatic pseudocysts and related complications].

On the basis of 45 cases of operated pseudocyst, the Authors tackle the problem of surgical tactis in treatment of these lesions and any complications. The paper outline the contribution that recent diagnostic methods--such as endoscopic retrograde cholangiopancreatography, computed tomography and ultrasonography--have made to solution of the problem and establishes the criteria for emergency or elective operation. In the first condition, consisting in cases of complications (haemorrhagic, suppurative, perforative etc.), abnormal development of pseudocysts and serious impairment of the patient's general conditions, the treatment of the pseudocyst generally takes the form of external drainage. The second condition, obtainable after a sufficient period of "ripening", usually consists in a cysto-digestive shunt or cysto-parenchymal demolition in view of the high morbidity arising from external drainage. Surgical treatment of the pseudocyst is completed by therapy of any basic chronic pancreatitis and by correction of probable associated lesions affecting the bile and digestive tracts and the splanchnic venous circulation. In the reported cases, 28 patients were treated by cysto-digestive shunt, 8 by cysto-parenchymal demolition and 9 by external drainage. There were 37 combined operations.
