Portal vein occlusion to increase the size of the future liver remnant (FLR) is well established, using portal vein ligation (PVL) or embolization (PVE) followed by resection 4–8 weeks later. Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) combines PVL and complete parenchymal transection, followed by hepatectomy within(More)
Most cancer deaths are caused by metastases, resulting from circulating tumor cells (CTC) that detach from the primary cancer and survive in distant organs. The aim of the present study was to develop a CTC gene signature and to assess its prognostic relevance after surgery for pancreatic ductal adenocarcinoma (PDAC). Negative depletion fluorescence(More)
BACKGROUND Portal vein ligation (PVL) or embolization (PVE) are standard approaches to induce liver hypertrophy of the future liver remnant (FLR) prior to hepatectomy in primarily non-resectable liver tumors. However, this approach fails in about one third of patients. Recently, the new "ALPPS" approach has been described that combines PVL with parenchymal(More)
AIMS Despite curative surgery for pancreatic ductal adenocarcinoma (PDAC), most patients develop cancer recurrence and die from metastatic disease. Understanding of the patterns of failure after surgery can lead to new insights for novel therapeutic modalities. The aim of the present study is to describe the patterns of recurrence after curative resection(More)
As our understanding of pancreatic cancer evolves, evidence is growing to support a role for cancer stem cells in this devastating disease. Cancer stem cells constitute a distinct subpopulation in the tumor and are considered to drive both tumorigenesis and metastasis; these cells are thought to be highly resistant to standard treatment modalities. Here we(More)
The aim of this study was to determine the incidence of symptomatic gallstone disease requiring cholecystectomy (CCE) after laparoscopic Roux-en-Y gastric bypass (LRYGBP) and to identify the peri-operative risk factors associated with postoperative symptomatic gallstone disease. Between August 2003 and November 2009, 724 patients underwent LRYGBP at the(More)
BACKGROUND In the elderly, there is no guideline for the treatment of irreparable rotator cuff lesions. The results of open or arthroscopic repair are variable. We hypothesized that the use of a reversed arthroscopic subacromial decompression (RASD) would yield comparable results. MATERIAL AND METHODS Between January 2004 and December 2006, thirty-eight(More)
Epithelial cell adhesion molecule (EpCAM) has been used as surrogate marker for the quantification of circulating tumour cells (CTC). Our aim was to prospectively study the value of a real-time RT-PCR assay for EpCAM detection in the peripheral blood and peritoneal cavity of patients undergoing pancreatectomy for pancreatic ductal adenocarcinoma (PDAC).(More)
PURPOSE The purpose of this study was to analyze changes in serum electrolyte concentration and renal function after hip arthroscopy. METHODS We studied 10 consecutive patients (4 men and 6 women; median age, 30.5 years [range, 20 to 50 years]) undergoing hip arthroscopy. Operating time, traction time, and perfusion volume of lactated Ringer solution (in(More)
Flank pain is caused by a variety of pathologies of which urinary stone disease is the most frequent. Eosinophilic ureteritis is a rare stenosing condition of the ureter. Eosinophilic ureteritis can cause flank pain and/or unilateral hydronephrosis. On pathological examination it is characterised by a marked infiltration of the submucosal layers by(More)
