Continuous peritoneal dialysis in acute experimental pancreatitis in dogs. Effect of aprotinin in the dialysate medium.

In 27 beagle dogs, acute necrotizing pancreatitis was induced by retrograde injection of autologous bile and trypsin into the main pancreatic duct. Animals were randomly assigned to the following treatments: group 1--(9 dogs) aprotinin 600,000 KIU/d by i.v.

[Hemodynamic status in liver cirrhosis with portal hypertension: a retrospective study on 49 patients].

The Authors report on the data obtained and their evaluation by means of analysis of seven variables and four indices, in 49 cirrhotic patients with portal hypertension and in 10 control patients. Haemodynamic analysis offers the possibility of identifying the dynamic transition stages of a response to stress showing varying degrees of compensation and establishing categories of patients on the basis of cardiovascular and metabolic parameters in relation to liver damage. The Authors, according to Siegel studies, retain that this is a valid method which enables us to obtain useful information on the haemodynamic status of the cirrhotic patient with portal hypertension.

Bilateral percutaneous cervical cordotomy: immediate and long-term results in 36 patients with neoplastic disease.

Thirty-six patients with neoplastic disease suffering from chronic bilateral pain were subjected to bilateral percutaneous cervical cordotomy. The technique and precautions to be taken in bilateral percutaneous cervical cordotomy performed either in one or two stages are described using a traditional or Levin's thermocouple-monitored electrode. The sequelae, complications and immediate and long-term results are reported.

Presence of duodenopancreatic feedback in minipigs and possible interference from the bile.

In two minipigs chronic pancreatic and duodenal fistulas, which allowed the diversion and the intestinal replacement of pancreatic secretion, were prepared. In a third minipig a chronic biliary fistula was also prepared so the bile secretion could be fed back into the intestine through a duodenal catheter. In these animals a chronic gastric fistula was made so gastric secretion could also be collected.
