[Endoscopic retrograde catheterization of Vater's ampulla in the diagnosis of bilio-pancreatic diseases].

The technique, indications and contraindications for endoscopic retrograde cholangiopancreatography are discussed. Some of the most demonstrative cholangiographic and pancreatographic pictures are described and the reasons that have led to a marked reduction in complications immediately after the examination are analysed. Therapeutical aids for limiting any slight disturbances connected with the examination are also presented. Finally, some morphological data useful for differentiating between inflammatory and neoplastic lesions in the juxta- and intrapancreatic biliary excretory way and the pancreas itself are considered.

[Criteria of diagnostic evaluation and results of surgical treatment in chronic pancreatitis].

Correct diagnostic evaluation of chronic pancreatitis pictures must of necessity be directed to recognition of recurrent and stable forms and identification of the pathogenetic cause of the clinical forms. This objective seems to be achieved more than satisfactions by the diagnostic protocol employed personally, the first stages of which include X-ray of the abdomen for the identification of possible pancreatic calcification, ultrasonography and computed axial tomography for the analysis of organ's morphology and structure, intestinal absorption and pharmacodynamic tests of the papillary excretory complex for the evaluation of functional state of the pancreas. At a second time, this diagnostic protocol includes endoscopic pancreatography for the analysis of the excretory duct and identification of possible calcareous concretions in its lumen, and district angiography, for information on the extreme viscero-vascular implications and the possibility of coexistence of district portal hypertension pictures. The resulting information dominates therapeutic choices by indicating the usefulness of performing a papillo-sphincteroplasty to handle the biliary aetiology in recurrent forms and Wirsung septoplasty for ductal ostial stenoses. The choice of shunts and resections is confirmed to the stable forms, with the use of the former in the event of ductal dilatation and of the latter in the absence of this and in the presence of more or less marked gland fibrosis. Derivative procedures also control treatment of chronic post-pancreatitis pseudocyst, with a clear-cut prevalence of cysto-gastric shunts over all the other possibilities.(ABSTRACT TRUNCATED AT 250 WORDS)

Hemangioma of the small bowel. Case report.

Cavernous hemangioma is a very rare disease if located in the ileum, but not an uncommon lesion if it occurs in the large bowel. The Authors report a case of small bowel cavernous hemangioma, and consider clinical, diagnostic and therapeutic aspects for an exact evaluation of the lesion.

Endoscopic polypectomy of the large bowel: management of cancer-bearing polyps.

From January 1974 to May 1979, among 2,338 endoscopic examinations of the large bowel, 184 polypectomies were performed. Forty-two cases of familial polyposis coli were excluded from this study. Of the remaining 142 cases, 21 had cancer foci: fourteen were mucosally confined carcinomas, and seven submucosally invading carcinomas. Endoscopic polypectomy was considered a radical treatment for the former and not satisfactory for the latter. Therefore macroscopic type of polyp, location of carcinoma in the polyp, and lymphatic and venous permeation were the main criteria evaluated for the strategy of treatment in cases of submucosally invading carcinoma-bearing polyps. Radical resections are necessary in cases of semipedunculated polyp with carcinoma located near the base, and in cases of pedunculated polyps with carcinoma extending to the stalk. However, as general criteria for the management of submucosally invading carcinoma-bearing polyps have not yet been established, radical resections are indicated in cases which do not fit the generally accepted criteria, in order to attempt a curative treatment. Endoscopic polypectomy therefore seems to be of great value in the early detection of colorectal cancers and their treatment.
