The effect of experimental liver transplantation on pH and the acid-base equilibrium by active and passive veno-venous bypass was examined. It is concluded that the use of active veno-venous bypass may considerably decrease but not completely prevent the development of metabolic acidosis by elimination of the phase.
Based on review of the literature and on their own material, authors have established that pancreatitis, following biliary and gastric operations, develops mostly at interventions performed on the papilla of Vater and/or around its region. The characteristic signs of the early postoperative. (2nd-4th day) pancreatitis are essentially confined to the pancreas (i.e. necrosis, abscess, erosion, bleeding, fistula). The time of early surgical intervention and the type of solution vary by patients. Recognition of the spreading of autolysis is possible by sonographic or computer tomographic control which also help in diagnosing further complications and indicating additional operations. Prognosis is poor and lethality is high and, consequently, the gastric or biliary operations involving the papilla of Vater or its region should be performed with particular caution. Postoperative pancreatitis can be a specific risk-factor of these operations.
Changes in heparin level during orthotopic liver transplantation were studied in experiments without the administration of heparin in dogs. It was established that the changes in heparin level might probably not play a role in giving rise to coagulopathy observed during liver transplantation. Their data also indicated that the rise in heparin level had originated not from the re-perfused liver but from the release of endogenous heparin.
Technique and advantages of thoracal sympathectomy, using the mediastinoscope, are described in this paper. Clear-cut evidence was produced to lasting suspension of sympathetic action during the follow-up period.
The lymph flow of the thoracic duct, the protein content of the lymph, bile flow and bile composition are studied during the first three hours of the recirculation phase in experimental liver transplantation. It is established that the lymph flow and the protein content of the thoracic duct decrease as a result of the interruption of hepatic lymph flow of a high protein concentration. The change in bile composition and flow is due to the reduced bile acid excretion of the transplanted hepatic tissue.
