Our technique of combined renal and segmental pancreas transplantation.

This case, however, confirms our hypothesis that intraperitoneal positioning of a segmental pancreatic graft into the Douglas' pouch and an end to side arterial anastomosis bring several advantages as far as venous thrombosis and tryptic lesions are concerned.

[Controlled results of standardized X-ray examination technique (author's transl)].

2000 patients were examined in our hospital within a period of 1 1/2 years using a standardized technique of x-ray examination of the stomach. Of these examinations, the gastroscopic, histological and partly also surgical results are now available from 241 patients. Hypotonic double-contrast technique, a highly dense, low-viscosity barium preparation and standardized documentation by means of 12 to 14 images taken with a 100 mm camera, have proved successful. The article reports on the accuracy of the x-ray examination based on these 241 results.

[Juvenile cadaver kidneys as suitable donor organs].

As several authors stated within the last few years and according to our experience as well cadaveric kidneys of young children are suitable for transplantation. Considering the shortage of transplantable organs en-bloc-transplantation should not be performed, even if this provides the opportunity to remove one kidney in case of surgical complications. On the other hand by transplanting a single organ one donor may help two recipients. Since it is known that kidneys of babies under 18 months do not guarantee sufficient function in adults, it should be a rule that kidneys of children under 18 months have to be transplanted en-bloc, whereas kidneys of older children can be transplanted solitarily without hesitation. Long term results with baby kidneys do in no way differ from kidneys of adults.

[Lymphocytic infiltrations in normal and pathological thyroid glands (so-called focal lymphocytic thyroiditis) (author's transl)].

A series of 1004 goitres removed surgically before (1959) and after (1970, 1975) the introduction of the iodine prophylaxis reveals an impressive increase in lymphocytic infiltration of the thyroid gland parenchyma. So-called focal lymphocytic thyroiditis is closely associated with the functional state of the organ. Furthermore, there is an increase in focal thyroiditis, especially in younger persons, after the introduction of iodine prophylaxis. Autoantibodies or clinical signs of inflammation were not found in these cases. Focal lymphocytic thyroiditis is seen as the expression of a regulatory function of the immunological system over the thyroid gland.

Expandable metal stents versus laser combined with radiotherapy for palliation of unresectable esophageal cancer: a prospective randomized trial.

BACKGROUND/AIMS: Because of the short life expectancy of patients with esophageal cancer, relief of dysphagia associated with low morbidity and mortality must be the aim of any therapeutic strategy. METHODOLOGY: A total of 39 patients with unresectable esophageal cancer were randomly allocated to either receive combined laser-percutaneous radiotherapy (group 1, n = 21) or to have a self-expanding metal stent placed (group 2, n = 18). Some patients in group 2 required initial laser therapy (group 2a, n = 8). Treatment efficacy was evaluated on the basis of improved dysphagia, restenosis, hospital stay, survival time and costs. RESULTS: Both treatments were able to significantly improve dysphagia. Restenosis occurred in 43% of group 1 and 22% of group 2 patients. In group 1, 2 patients had severe bleeding episodes and 2 patients developed esophago-tracheal fistulas. One group 1 patient died due to uncontrollable bleeding and 1 patient to recurrent aspiration. No treatment-related death was observed in group 2. Hospital stay was 30.0 (mean: 5.4) days in group 1, 18.9 (mean: 4.2) days in group 2a and 7.1 (mean: 3.1) days in group 2b. There was no statistical difference between the 3 groups with regard to survival. Costs were highest in group 1 and lowest in group 2b. CONCLUSIONS: The treatment of unresectable esophageal cancer with self-expanding metal stents appears to be simple, safe, as good as laser combined with radiotherapy and cost efficient.

Cell profiles in serial bronchoalveolar lavage after human heart-lung transplantation.

The aim of this study was to investigate serial changes in bronchoalveolar lavage (BAL) cell profiles after human heart-lung transplantation and to assess the clinical value of BAL cytology in the differential diagnosis of complications in the transplanted lung. BAL was performed serially on 23 occasions on four patients. Elevated counts of neutrophils (4-48%) were observed in all preparations, with peak values in the early postoperative phase, in bacterial infections and in cytomegalovirus pneumonitis. In the last condition, BAL cytology also showed relative lymphocytosis (less than or equal to 50%) with high proportions (less than or equal to 50%) of HLA DR-positive T lymphocytes. No characteristic light microscopic pattern was observed in acute pulmonary rejection. However, scanning electron microscopy revealed elevated counts (greater than 5%) of "villous" macrophages in BAL obtained during or shortly after episodes of rejection. BAL cytology may be helpful in differentiating viral and bacterial infections, while scanning electron microscopy seems to be more suitable to the diagnosis of acute pulmonary rejection.
