[Cystic dilatation of the choledochus associated with stenosis of the hepatic duct bifurcation. An analysis of a clinical case]. / Dilatazione cistica del coledoco associata a stenosi della biforcazione dei dotti epatici. Analisi di un caso clinico.

The authors report a case of cystic dilatation of the choledochus associated with narrow stenosis at the confluence of the left and right hepatic ducts which was found to be inflammatory on histological examination. This pathology is becoming an increasingly more commonplace clinical finding. The case reported here is particularly interesting owing to the onset of the disease and the way in which it was treated. An attempt was made to treat the patient using a simple operation which was to the least radical possible. The authors take this opportunity of reviewing the literature on the subject.

[Cancer of the rectum and sigmoid. Our experience]. / Il cancro del retto-sigma. Nostra esperienza.

The paper reports the Authors' experience during the period 1989-91 and refers to 80 operated cases of rectum-sigma cancer. Given that data reported in the literature affirm that the limit of oncological safety is 1.5-2 centimetres distal from the tumour, and owing to their use of mechanical staplers, the Authors were able to use the preferred anterior section followed by low or very low colo-rectal anastomosis in 96% of cases. Miles' technique for abdomino-perineal amputation was only resorted to in 4% of cases. Tumours parameters, short- and medium-term complications and the results of a short-term follow-up are all discussed. The Authors compare their experience with that of other researchers reported in the literature.

[Neurilemmoma of the stomach. Presentation of a case]. / Il neurilemmoma dello stomaco. Presentazione di un caso.

The paper describes a recent case of neurilemmoma of the stomach. Following a review of the literature, the Authors focus their attention on the diagnostic difficulties and the choice of therapy. Tomography, arteriography and gastroscopy with multiple biopsies may at times be misleading depending on the development of the tumour. Most Authors agree that local resection or, when possible, enucleation are the most appropriate forms of therapy.
