[Emergency surgery problems: selective decompression of esophagogastric varices].

The physiopathological premisses of portosystemic anastomosis and the modern approach to this question are explained. Stress is laid on the general and haemodynamic advantages offered by selective shunts and 6 cases (4 distal splenorenal and 2 coronarocava shunts) are presented. As yet the postoperative period is not long enough to enable a final judgement to be formed. However, it can be stated that the success of this form of management is primarily determined by the proper choice of candidates, i.e. patients with non-decompensated initial cirrhosis and unimpaired portal hepatic flow.

[Villose polyps of the duodenum].

A case of villous polyps of the duodenum is reported, world-wide series also being considered. The various symptomatologies and percentages of malignant transformation and localization are described and stress laid on the superiority of endoscopy to radiography owing to the fact that it gave: 1) exact site and nature diagnosis of the lesion during the haemorrhagic phase; 2) exact histological and topographical diagnosis, following the haemorrhage, paving the way to the subsequent surgery.

[Use of the computer in intensive care. A program for instruction and diagnosis of changes in acid-base equilibrium].

A method for assessing the acid-base balance in patients admitted to the Intensive Care Department, making use of the Graphic Display option of a minicomputer is presented. Patient condition can be plotted on present graphs whose coordinates are the pH and PACO2 measured at successive moments. It is thus possible to visualise the behavior of acid-base balance over a period, as well as the extent of renal or respiratory compensation. The data relating to a group of patients are reported by way of illustration.

[Intraoperative choledochoscopy].

Intraoperative choledochoscopy is examined and the instruments mostly employed for this purpose are described, with particular reference to the Olympus CHF B2, and personal modifications to the same, as used in the present study. The indications for the examination and the technique required are explained. It is especially useful in diseases of the bile ducts, and superior to cholangiography, which often fails to diagnose intrahepatic calculosis and small, multicentered tumours. A series of images relating to calculosis of the bile ducts, biliary neoplasia, the choledochus in lesions of the head of the pancreas, and the normal appearance of the bile ducts is presented.

[Long-term results of gastric resection with reconstruction, using the Billroth I method].

Clinical, radiological and endoscopic results at follow-up about 1-5 yr after surgery in a series of 62 patients subjected to Billroth I resection are compared with those in the literature. Recurrence of ulcers was observed in 8% (as opposed to 5% with the Billroth II). In addition, there was a marked reduction in the incidence of post-resection diseases, with less serious forms of dumping, sounder digestion, and smaller weight losses.

[Problems in emergency surgery. Massive pulmonary embolism. Clinical and diagnostic aspects].

In spite of the many advances in diagnosis, pulmonary embolism is still hard to identify, one problem stemming from the similarity of its clinical signs with heart and lung conditions. The present study was carried out on 17 patients affected by massive pulmonary embolism. Clinical aspects and diagnostic problems are discussed, with particular regard to the data supplied by chest X-ray, catheterism of the right cardiac cavities and angiopneumographic investigation.

[Problems in emergency surgery: acute mesenteric vascular occlusion].

Twenty-one cases of acute mesenteric occlusion are presented. Stress is laid on the difficulty of reaching a diagnosis in time to enable disobstruction to be carried out. In the reported series, diagnosis was established 1-8 days after the onset of symptoms. When radical surgery was performed (extensive resection occasionally coupled with right hemicolectomy), postoperative mortality was high and transit and nutritional problems brought about by the shortness of the residual gut were encountered.
