    Notes: Summary We have developed a technique for allotransplantation of the pancreas in pancreatectomized dogs. This method employs a graft of the whole pancreas and duodenum (P-D) which is placed in a heterotopic position with drainage of exocrine secretions of the grafted pancreas into the recipients jejunum via the graft duodenum. Venous return from the P-D allograft is directed into the systemic rather than the portal venous system. Panereatectomized dogs with such P-D allogrâfts have survived many months if immunosuppressive drugs are given to prevent rejection. We have also found that the P-D graft can survive in vitro without circulation and retain the ability to secrete insulin when stimulated by blood glucose perfusion after as long as 24 h of in vitro preservation. Preservation is done with a chamber which combines hypothermia to 5 °C and hyperbaria to 4 atmospheres of oxygen. Armed with this knowledge, we have made P-D allografts combined with renal allografts in five patients with insulin dependent, juvenile onset diabetes mellitus with terminal nephropathy. Two of these patients have left the hospital and have normal function of the P-D and renal allografts. Neither patients has required insulin since transplantation, 11 months and 7 months ago. P-D allotransplantation is now planned for insulin dependent, juvenile onset diabetics who have significant but not terminal nephropathy or retinopathy. If P-D allotransplantation is found to slow, cause to regress, or prevent the vascular deterioration characteristic of diabetes mellitus, then it may become the most frequent organ transplant because of the increasing incidence of diabetes mellitus.

    Description / Table of Contents: Zusammenfassung Der Vorteil der vorliegenden Perfusionsstudie des Pankreas in vitro ist der, daß er eine Vorhersage der funktionellen Lebensfähigkeit des perfundierten Pankreas in direkter Beziehung zur spezifischen Organfunktion erlaubt. Das Pankreas mit Duodenum wurde Hunden entnommen und für 3 Std mit einer Blut-Ringer-Lactatlösung mit einem Membranoxygenator, einer Pulspumpe und einem Wärmeaustauscher bei 37°C perfundiert. Aufgrund der vorliegenden Untersuchungen erweisen sich der Insulinausstoß nach Glucosegabe und die Pankreassekretion nach Sekretin-Reiz als besonders zuverlässige Kriterien in der Beurteilung der Lebensfähigkeit des Organs. Der durchschnittliche Sauerstoffverbrauch des Pankreas liegt bei 0,77 ml 02/100 g. Ein durchschnittlicher Flow von 80 ml/min bei einem Druck von 75 mm Hg erweist sich in der vorliegenden Versuchsanordnung als nützlich. Makroskopische und histologische Untersuchungen bestätigen die Ergebnisse.
    Notes: Summary An advantage of the current perfusion-test in vitro is that it allows prediction of the functional viability of the perfused pancreas in direct relation to the specific organ function. The canine pancreas including the duodenum has been perfused for 3 h with a membrane oxygenator, a pulsatile pump and a heat exchanger at a temperature of 37°C. Among the criteria used in this study the insulin-output into the venous blood in response to glucose administration as well as pancreassecretion after secretin stimulation were found to be the most reliable indications as to the viability of the pancreas. This is further supported by an average oxygen consumption of 0.77 ml 02/100 g at a constant flow of 80 ml/min and a pressure of 75 mm Hg, and the macroscopical and histological findings.
