Hemorrhage caused by inflammatory vessel erosion represents a life-threatening complication after upper abdominal surgery such as pancreatic head resection. The gold standard therapeutic choice is an endovascular minimally invasive technique such as embolization or stent placement. Hepatic arterial hemorrhage in presence of pancreatitis and peritonitis is a(More)
Esophageal perforations are life threatening emergencies associated with high morbidity and mortality. We report on 22 consecutive patients (age 20-86; 13 female and 9 male) with an oesophageal perforation treated at the university hospital Duesseldorf. The patients' charts were reviewed and follow-up was completed for all patients until demission, healed(More)
Rectovaginal fistuale (RVF) are a serious and disabling problem for the patients and a surgical challenge for the treating physicians. The most common causes of RVF are postoperative complications, inflammatory bowel disease, complications of radiotherapy, obstetric complications, and neoplasia. Therapeutic options are diverse and results often(More)
The association of EpCAM expression with the progression of gastric cancer remains unclear. Here, we investigated the expression of EpCAM in gastric cancer subtypes and correlated the data to tumor cell proliferation and clinicopathologic factors. The intratumoral expression of EpCAM was assessed in 163 primary gastric cancers (61 diffuse-, 62 intestinal-,(More)
INTRODUCTION Down-regulation of E-cadherin (CDH1) and epithelial-mesenchymal transition (EMT) are considered critical events for invasion and metastasis of colorectal carcinoma. Here we tested whether the important regulators of E-cadherin expression SNAI1 and TWIST1 are already detectable in human colorectal adenomas. METHODS RNA was extracted from a set(More)
BACKGROUND In intestinal epithelium, tyrosine kinase receptor Ephrin B3 (Eph B3) maintains the architecture of the crypt-villus axis by repulsive interaction with its ligand ephrin-B1. While loss of Eph B3 is linked to colorectal cancer initiation, overexpression of Eph B3 in cancer cell lines inhibits growth and induces functional changes with decreased(More)
Intrahepatic endometriosis is one of the rarest forms of atypical endometriosis; only eighteen cases have been reported in the English literature. We describe the case of a 32-year-old woman, who presented with persistent, non-cyclical upper right quadrant abdominal pain, a central liver cyst, and no history of endometriosis. Three years previous, she was(More)
Cytochrome P450 epoxygenases (CYP450) have been recently shown to promote malignant progression. Here we investigated the mRNA and protein expression and potential clinical relevance of CYP2C9 in esophageal cancer. Highest expression was detected in esophageal adenocarcinoma (EAC; n=78) and adjacent esophageal mucosa (NEM; n=79). Levels of CYP2C9 in EAC and(More)
Snail1 is a transcription regulator of E-cadherin. The loss of E-cadherin seems to be a crucial step in the process of Epithelial-mesenchymal transition (EMT). EMT initiates invasion and proliferation in many tumours. Overexpression of Snail1 is known to be associated with poor outcome in several solid tumours. The aim of this study was to analyse its(More)
To date, very little is known about the development of benign organic hyperinsulinism and its metastatic potential. Typical morphologic, biochemical, or genetic differentiations for benign or malign tumor course of insulinomas do not exist. As signaling pathways may affect pancreatic cancer development and the maintenance of the neoplastic phenotype, the(More)
