Importance of Pancreatic Enzyme Replacement Therapy after Surgery of Cancer of the Esophagus or the Esophagogastric Junction.

After surgical treatment of cancer of the esophagus or the esophagogastric junction we observed steatorrhea, which is so far seldom reported. We analyzed all patients treated in our rehabilitation clinic between 2011 and 2014 and focused on the impact of surgery on digestion of fat. Reported steatorrhea was anamnestic, no pancreatic function test was made.

Percutaneous intragastric catheter (PIC) for administration of an unpalatable substance to large animals.

We studied an easy and reliable technique for administration of an unpalatable substance to large animals. There were three groups of pigs: group I (n = 6) received 1 g ethanol/kg body weight per day orally with water for 24 days, group II (n = 6) received 2 g ethanol/kg orally with water for 24 days and 4 g ethanol/kg via percutaneous intragastric catheter (PIC) for the next 24 days, group III (n = 6) received 6 g ethanol/kg via PIC for 72 days. The catheter was placed after insufflation of the stomach using an orogastric tube.

Iatrogenic tracheobronchial ruptures - treatment and outcomes.

In the present paper we discuss the indication and follow-up of 42 patients with iatrogenic tracheobrochial ruptures. Thirty-five patients were treated by operation and 7 patients were treated conservatively. In the operated patients, four developed an insufficiency of the tracheal closure and the rupture related mortality was 2.

Does the inactivation of leukocytes in blood transfusions during and following liver transplantation by gamma-irradiation have an impact on rejection and infection rate?

Background: Leukocytes transmitted in blood products exert a variety of immunological side-effects. Experience with bone marrow transplant recipients has shown that these can be induced even by very few cells. In liver transplant recipients, who usually receive large amounts of blood products, the effects of transfused leukocytes with regards to the rates of rejection and infection have not yet been investigated.

Does the expression of c-kit (CD117) in neuroendocrine tumors represent a target for therapy?

Neuroendocrine tumors are very heterogeneous, develop from a variety of tissues, and can be difficult to diagnose. Without the clinical manifestation of metastases, it is often difficult to characterize them as malignant. Even so-called completely (R0) resected tumors can spread clinically visible metastases within a few months after initial surgery.

Arterialisation of the portal vein as a model for the induction of hepatic fibrosis: description of microsurgical models in the rat.

Within the framework of liver transplantation, arterialisation of the portal vein in the case of non-recanalisable thrombosis has been reactivated. However, one of the consequences of this vascular reconstruction is the development of hepatic fibrosis. Clinical experience has shown that the development of fibrosis can be avoided by reducing portal inflow.

Effects of portal vein arterialization on regeneration and morphology in liver transplantation: investigations using the rat model.

Background: Portal vein arterialization (PVA) has been proposed as a technical variant in liver transplantation in the case of non-recanalizable thrombosis. The present study investigates the effects of the arterialized portal vein on the function, morphology, and regenerative behavior of the liver.

Methods: Different PVA techniques, including orthotopic liver transplantation, were used in a rat model.

Pancreatic neuroendocrine tumor with ectopic adrenocorticotropin production upon second recurrence.

We present a 54-yr-old woman with ectopic corticotropin syndrome caused by a neuroendocrine tumor of the pancreas. At initial presentation, the patient suffered from diarrhea, heartburn, and nonspecific abdominal pain. There was no evidence of Cushing's syndrome.

Impact of changing immunosuppressive monotherapy from Cyclosporin A to Tacrolimus in long-term, stable liver transplant recipients.

A number of studies have reported a lower atherogenic lipid profile in liver transplant recipients under tacrolimus (FK506) than in those under cyclosporine A (CyA) immunosuppression. This has mainly been attributed to the steroid-saving effect of FK506. However, the effects of converting CyA to FK506 monotherapy on lipid metabolism have not been specifically investigated.

Anti-CD20 monoclonal antibody treatment of Epstein-Barr virus-induced intrahepatic lymphoproliferative disorder following liver transplantation.

Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorders (PTLDs) are a common cause of death in transplant patients. Their incidence following liver transplantation is reported to be between 0.5% and 4%.

Portal vein arterialisation as a technical option in liver transplantation: impact on function, regeneration, and morphology of the liver following hemihepatectomy in pigs.

Background: Arterialisation of the portal vein has been propagated as a technical variant in liver transplantation. However, the consequences of this unphysiological vascular supply are insufficiently known.

Methods: Twenty-seven healthy pigs were subjected to a left hemihepatectomy and divided into three groups.

Outcome of patients with pre-existing portal vein thrombosis undergoing arterialization of the portal vein during liver transplantation.

Arterialization of the portal vein is being propagated as a technical possibility in liver transplant recipients with pre-existing portal vein thrombosis. In our own small series, portal vein arterialization (PVA) was carried out in four patients undergoing orthotopic liver transplantation. In three of these cases, the portal vein was anastomosed to the aorta via an interposed iliac artery, and in one case, directly to the hepatic artery.

Prognosis of a large cohort of patients with hepatocellular carcinoma in a single European centre.

Background/aim: Only a few follow up data are available for patients with hepatocellular carcinoma (HCC) in Europe and the USA. Therefore, we analysed all HCC patients admitted to our hospital between 1988 and 1999.

Methods: We documented aetiology, stage (HCC: Okuda and UICC classifications, liver cirrhosis: Child-Pugh score), and diagnostic and therapeutic measures of 281 consecutive HCC patients.
