[Are breast biopsies adequately funded? A process cost & revenue analysis]. / Ist die Mammabiopsie ausreichend finanziert? Eine Prozesskosten & Erlösbetrachtung.

PURPOSE: The objective of the study was to determine whether the various breast biopsy procedures specified in the S 3 guidelines are sensibly represented within the current German health system as considered from a cost evaluation perspective. MATERIALS AND METHODS: This prospectively designed multicenter study analyzed 221 breast biopsies at 7 institutions from 04/2006 to 01/2007. Core needle biopsies, vacuum-assisted biopsies and surgical open biopsies under sonographic or mammographic guidance were evaluated. During an analysis of process costs, the individual process steps were recorded in diagrammatic form and assigned to the true consumption of resources. The actual resource consumption costs were entered. A process-related breakeven analysis was conducted to check whether the reimbursement of individual biopsy types covers the costs. RESULTS: Only sonographically guided core needle biopsy and surgical open biopsy are adequately reimbursed in the current German health system. All other breast biopsies indicate a negative profit margin. The principal reasons for under-funding are found in the area of reimbursement of investment and non-personnel costs. CONCLUSION: The reimbursement of breast biopsies must be improved in order to guarantee nationwide care of the population using the breast biopsy methods recommended in the S 3 guidelines and to avoid disincentives with respect to breast biopsy indications.

[Diagnostic and therapeutic strategies in hepatocellular adenoma]. / Diagnostische und therapeutische Strategie beim hepatozellulären Adenom.

While liver hemangioma and focal nodular hyperplasia are not considered an indication for surgery in asymptomatic patients resection has been recommended for hepatocellular adenoma because of the risk of rupture and malignant transformation. Problems arise from differential diagnosis and the appropriate surgical radicality including the indication for liver transplantation. This retrospective analysis deals with 58 patients who underwent surgery for hepatocellular adenoma: resection of different extension: n = 54, liver transplantation n = 4. In 39.6% of the patients the tumor was an incidental finding. In 62.0% of the character of the lesion was unclear prior to surgery. Tumor rupture and bleeding occurred in 17.2%, malignant transformation in 6.9%. Surgical morbidity was 27.6%, mortality 5.2% with the transplant patients alive for 1.5, 7, 9 and 10 years. Two and five years after resection 2 patients developed hepatocellular carcinoma in the liver remnant. The results confirm the indication for surgery in hepatocellular adenoma. Diagnostic approach for solid liver tumors without serum increase of tumor markers should rule out FNH and hemangioma. In all other patients surgery should be considered whenever possible with the radicality of malignant disease. Liver transplantation can be discussed even in asymptomatic patients with multiple adenoma.
