[The determination by computed scintigraphy of the evacuation time of the resected stomach under the administration of salbutamol and dopamine].

The evacuation time (T1/2) of the stomach was determined in the patients with partial gastric resection by a sequential computerized scintigraphic method. The effect of Salbutamol and Dopamine was followed on T1/2 and the scintigraphic surface of the stomach (appreciated indirectly by measuring the longitudinal and transversal diameters). Salbutamol prolongs significantly T1/2, from 6.41 +/- 2.72 minutes to 12.33 +/- 6.45 minutes. The scintigraphic surface of the resected stomach is not slightly modified by Salbutamol. Dopamine prolongs very much T1/2, from 13.00 +/- 4.01 minutes to 75.03 +/- 24.36 minutes, in parallel with the increase of the scintigraphic image of the stomach. Our investigations lead to the conclusion that Salbutamol, given per os, may become a new therapeutic mean in the dumping syndrome.

[Contribution of sequential scintigraphy with 131I-BSP to the differential diagnosis of jaundice (author's transl)].

Patients with constitutional hyperbilirubinemia and with extra intrahepatic cholestasis have been explored by means of sequential scintigraphy, with the following results: 1. in Gilbert's syndrome liver uptake and output of 131I-BSP were normal; 2. in the Dubin-Johnson syndrome liver uptake and plasma clearance of 131I-BSP were normal; the substance was retained for a long period (2 hrs) in the liver without any tendency to be excreted; 3. in the Rotor syndrome 131I-BSP uptake was delayed and liver clearance prolonged; 4. in total biliary obstruction no intestinal activity could be recorded even in the late registrations (the latest after 24 hrs); 5. in partial extrahepatic biliary obstruction there was a normal liver uptake with an abnormal retention in the choledochus and a delayed excretion (more than 2 hrs); and 6. in intrahepatic cholestasis 131I-BSP liver uptake, retention and excretion were delayed; differentiation of these cases from total biliary obstruction is difficult. Late determinations, the last 24 hrs after injection of the tracer, were performed in these cases, in order to exclude a total obstruction with parenchymal injuries, by assessing the enteral output.

[Electronic data processing of liver scintigrams in chronic hepatitis (author's transl)].

Following administration of 150 muCi of colloidal 198Au numerical scintigrams of the liver and the spleen were obtained in about 200 patients with various forms of chronic hepatitis or with liver cirrhosis as well as in 24 control persons. The data so obtained were electronically processed and the relative activities of the liver, the spleen and both liver lobes compared. Differences of diagnostic value were observed between the various stages of chronic hepatitis.
