ABSTRACT

BACKGROUND: Late metastasizing into pancreatic tissue is a special hallmark of renal cell carcinomas (RCC). A very low prevalence leads to scarce data about therapy, prognosis and spreading pathways. The aim of the study was to analyze whether a high fat content in the pancreas facilitates RCC metastases formation. A model for density measurement of pancreatic tissue has been developed and evaluated. Pancreatic fat content was measured comparing Hounsfield units (HU) of CT scans. METHODS: In a consecutive single centre retrospective database of 3600 patients with pancreatic resections, only 12 patients (0.3%) cases of RCC metastases in the pancreas were found. HU were measured in 3 pancreatic regions: head, body and tail in patients' CT scans. HU values were compared to a control population and results aligned with recent literature. RESULTS: We revealed a prevalence of pancreatic metastases of RCC in 0.3% of cases. The formation of RCC in the pancreas occurred within 14 ± 5.6 years after initial diagnosis of RCC. 83.3% of the patients were alive after a follow-up period of up to 48 months. Clinical data analysis revealed an affinity for metastatic formation to lipomatous pancreas. This could be objectivized by HU analysis in CT scans. CONCLUSION: Pancreatic metastases occur late after the first diagnosis of renal carcinoma and show an affinity for lipomatous pancreatic tissues. Due to its rarity in occurrence, multicentric studies are highly recommended to further analyze this correlation between fatty pancreas and RCC.

ABSTRACT

BACKGROUND: Tuberculosis (TB) is among the 10 leading causes of global deaths and is a special threat to immunocompromised patients with human immunodeficiency virus (HIV). Due to migration from endemic areas cases in central Europe can also increase. OBJECTIVE: This article gives an overview of background information, detection methods, treatment and the role of surgery in abdominal manifestation of a systemic infection. MATERIAL AND METHODS: A PubMed search was carried out using the following keywords: abdominal TB, incidence, symptoms, diagnostics, treatment and surgery. RESULTS: The detection of TB in cases of abdominal manifestation can be carried out via percutaneous biopsy; however, laparoscopy is recommended due to the better detection rate, low complication rate and its ability to differentiate other diseases, such as peritoneal carcinomatosis and lymphomas. Antituberculous drugs are the primary treatment. An acute abdomen can occur in up to approximately 30% of cases. Complications such as strictures and perforations require surgical treatment. CONCLUSION: Although the prevalence of TB is decreasing, the infection causes more than 1 million deaths per year. The correct diagnosis can be impeded by a misleading clinical presentation. A multidisciplinary approach enables rapid and efficient diagnostics and treatment.
