The Authors study the statistics of the Verona Surgical Centre, concerning 5 cases of colovesical fistula. They support the two-time operation, that is, the colon resection with colo-colic anastomosis sheltered by a decompressive transversostomy and stitching of the vesical breach. They affirm the usefulness of the operation according to Hartmann in patients facing a greater operative risk.
The Authors describe 2 cases of anorectal melanoma, which underwent operation in the Surgical Clinic of Verona in the years 1981-83. They review the literature confirming the high malignancy of this neoplasm, the poor prognosis forecasting a demolishing surgical treatment only. They, at last, once again affirm the principle whereby the results of such surgery are proportional to the stage of evolution the neoplasm is caught in, and the difficulty to reach a precocious diagnosis is therefore one of the main reasons for the scanty remote results of such surgery.
The Authors, on the basis of the casuistry of the Verona Surgical Centre, concerning the interventions for Crohn's disease from 1973 up to 1983, and comparing the data of literature, study the problem of appendicectomy in Crohn's disease. They suggest the operation of appendicectomy both when there are signs of appendicopathy in course, joined to a pathology of the last ileum ansa, and in presence of apparently sound appendix and clear signs of ileum Crohn's disease. They think it opportune to avoid appendicectomy only in presence of clear signs of involvement of caecum by the morbid process.
The Authors face the problems involved in the colonic familial polyposis, with particular attention to the surgical treatment of subjects bearing neoplastic degeneration. They, moreover, report their clinical experience, and compare it with the experience of other centres.
The Authors show a case of rectal ampulla carcinoid, and review the literature thereabout. They suggest the removal through sphincter according to Mason, which technique, in their opinion, can ensure a satisfying radicalness when the diameter of carcinoid is shorter than 2 cm.
The authors show their experience about the surgical treatment of colonic perforations in course of neoplastic disease. Their casuistry is compared with those of other centres.
The authors report their experience in the surgical treatment of the cancer of splenic flexure. The neoplasiae arising in such place are usually diagnosed in a more advanced phase than in the other colon segments. This results in a survival at a shorter interval.
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.
Personal experience of 135 operations on the left colon and the rectum, with simultaneous formation of decompressive transversotomy, is presented. According to the Authors, decompressive transversotomy is the sole method capable not of avoiding anastomotic dehiscences, but of ensuring that they do not become clinically manifest, and hence of reducing the mortality connected therewith. The doubts sometimes raised with regard to the method seem in the Authors' opinion to be linked to technical shortcomings in performance of the transversotomy itself.
The routine technique used by the Authors for performance of decompressive transversotomy in operations on the left colon and the rectum is described. The technique for extraperitoneal closure of the stoma is described in detail: the method is easy to perform and does not involve any noteworthy postoperative complications. Long-term follow-ups demonstrate that there are no functional disorders connected with adhesion of the organ to the abdominal wall.

The authors describe one case of cystadenoma of the bile ducts removed by left hemi-hepatectomy. They stress the importance of a complete angiographic examination, both in the arterial and in the venous return phase, for diagnostic purposes and correct planning of the surgical procedure.
Following a brief introduction in which they outline the frequency of colonic angiomatosis and its characteristic symptom triad, the authors describe one case of this condition come to their observation and treated surgically. Next they discuss the classification, differential diagnosis versus other colonic diseases and disorders, available diagnostic aids, and therapeutic resources. They stress in particular the difficulty of diagnosing this condition correctly, to the point where definite recognition is often made only by exploratory laparotomy.
