OBJECTIVE Transanal endoscopic microsurgery (TEM), a minimally invasive technique has been employed in the excision of benign and well-selected malignant rectal tumours since June 1998. We present a prospective descriptive study and analyse the currently accepted indications. PATIENTS AND METHODS Over a 4-year period 100 patients underwent TEM for(More)
BACKGROUND The 24-hour continuous infusion of 5-fluorouracil (5-FU) and folinic acid (FA) as part of several new multidrug chemotherapy regimens in advanced gastric cancer (AGC) has shown to be effective, with low toxicity. In a previous phase II study with 3-weekly bolus 5-FU, FA and mitomycin C (MMC) we found a low toxicity rate and response rates(More)
In the obstructed gut, nitric oxide (NO) may influence intestinal barrier function and translocation of bacteria. By using a novel experimental approach, we investigated the effect of supplementation and inhibition of NO synthesis on the time interval necessary for translocation of green fluorescent protein-transfected Escherichia coli (GFP-uv E. coli) in a(More)
BACKGROUND Existing animal models provide only indirect information about the pathogenesis of infections caused by indigenous gastrointestinal microflora and the kinetics of bacterial translocation. The aim of this study was to develop a novel animal model to assess bacterial translocation and intestinal barrier function in vivo. METHODS In anaesthetized(More)
BACKGROUND Primary intestinal non-Hodgkin's lymphoma (I-NHL) is much less frequent than gastric lymphoma and has hardly been studied in prospective trails. To the surgeon, patients frequently present with abdominal emergencies. PATIENTS AND METHODS A consecutive series of patients subjected to surgery because of I-NHL between 1998 and 1999 was evaluated(More)
BACKGROUND Infections are frequent complications and determine clinical course and outcome in severe pancreatitis. A novel animal model was used to assess minimal transit time of bacterial translocation (BT) across the gut mucosa in vivo using green fluorescent protein-transfected Escherichia coli and intravital video microscopy. METHODS Three hours after(More)
OBJECTIVE In experimental studies of capillary blood flow that use intravital video microscopy, organs are exposed in observation chambers implanted into the animal. In this article we describe an abdominal cavity chamber for intravital video microscopy of gut mucosa microcirculation during increased intra-abdominal pressure. DESIGN Prospective,(More)
BACKGROUND Intraoperative hyperthermic peritoneal chemotherapy (IHPC) after total gastrectomy for advanced, serosa-penetrating gastric cancer has been demonstrated in several studies to reduce the incidence of peritoneal carcinosis and to prolong survival. METHODS In a prospective pilot study, nine patients with advanced gastric cancer were selected to(More)
A simple technique to produce your own atraumatic suture is described. All that is needed is a simple injection needle and any kind of thread.The thread is introduced into the cavity of the needle and fixed by squeezing its end after having broken the hub. This method is very easy to apply and extremely economical.
The prognosis of peritoneal spread from gastrointestinal cancer and subsequent malignant ascites is poor, and current medical treatments available are mostly ineffective. Targeted chemotherapy with intraperitoneal prodrug activation may be a beneficial new approach. L293 cells were genetically modified to express the cytochrome P450 enzyme 2B1 under the(More)
