Isolated varices of the gastric fundus--endoscopic diagnosis and surgical treatment.

Isolated gastric varices in patients with portal hypertension are a relatively rare source of bleeding into the gastrointestinal tract. Endoscopy is a very valuable method of diagnosis in such cases. The authors report their own observation of gastric varices, well documented with the endoscopic technique before and after surgery. Varices of the gastric fundus are always an indication to surgical management. On the basis of their own experiences made with 5 patients, the authors recommend a direct intervention in form of an extragastric suture or resection of the convolution of the varicose veins, in selected patients simultaneously complete with a portasystemic shunt.

[Studies of hepatobiliary function with a scintillation camera and electronic data processing)].

The authors performed the sequential scintigraphy after intravenous application of 131I-BSP using the scintillation camera. During the first 60 minutes the pictures of the liver and of the mesogastrium were recorded in one-minute intervals on the digital magnetic tape. The following scintigrams were then recorded after 3 and 24 hours after the injection. Choosing the region of interest the authors noted the histograms above the liver and above the mesogastrium, evaluated then the proportion of impulse rate above the liver and mesogastrium in measured intervals and obtained using the digital computer the velocity coefficient of the radioactivity accumulation in the liver as liver chromoexcretive function parameter. The results were compared with the standard test of the 45-minutes retention of the BSP, with the analysis of the curve measured above the temporal region, with the clinical status as well as with the results of other auxiliary examination methods. According to the first experiences gained when examining 91 individuals the described method proves to be very useful.
