BACKGROUND Postoperative surgical site infections are one of the most frequent complications after open abdominal surgery, and triclosan-coated sutures were developed to reduce their occurrence. The aim of the PROUD trial was to obtain reliable data for the effectiveness of triclosan-coated PDS Plus sutures for abdominal wall closure, compared with(More)
In the last 3 years 9 patients with gastrointestinal stromal tumors (GIST) underwent surgery at our department. All cases were with very atypical process. From these patients 3 interesting cases are described in more details. A 75-years-old woman with gastroscopically verified endoluminal tumour in the proximal third of stomach, 6x7 cm, 76-years-old man(More)
BACKGROUND The purpose of this study was to review surgical experience with gastrointestinal stromal tumours (GISTs) at a single tertiary university hospital, and to identify morphological and genetic prognostic markers of tumour progression. METHODS Forty-eight GISTs from 39 patients were reviewed retrospectively. The prognostic significance of DNA copy(More)
While the oncological outcome of patients with rectal cancer has been considerably improved within the last decades, anorectal, urinary and sexual functions remained impaired at high levels, regardless of whether radical surgery was performed open or laparoscopically. Consequently, intraoperative monitoring of the autonomic pelvic nerves with simultaneous(More)
BACKGROUND Intravital microscopy allows direct visualization of the hepatic microvasculature. We report on a novel application of this technique using a chamber model that simulates the conditions of pneumoperitoneum. METHODS For this purpose, we designed a peritoneal cavity chamber for rats. In the present study, we evaluated the technical procedure(More)
BACKGROUND The transmembrane glycoprotein CD133 (cluster of differentiation 133; also known as Prominin or PROM1) has been described as a potential stem cell marker in colorectal cancer and is associated with higher tumorigenic potential and resistance to radiochemotherapy (RCT). In this study, CD133 expression was evaluated in pre-RCT tumor biopsies and(More)
BACKGROUND AND AIMS The impact of laparoscopy on tumor progression is still unclear. This study investigated the effect of CO(2) pneumoperitoneum on the intra-abdominal growth of human colon carcinoma independently of the effect of the immune system. METHODS SCID mice underwent either median laparotomy or laparoscopy. Human colon carcinoma cells were(More)
Basaloid squamous cell carcinoma (BSCC) and carcinosarcoma of the esophagus are rare entities, making up fewer than 2% of esophageal malignancies. Comparative genomic hybridization (CGH) in 1 case of BSCC and 2 cases of carcinosarcoma and subsequent array CGH in 1 case each of BSCC and carcinosarcoma revealed common chromosomal gains at 2p25.3-2p12,(More)
In gastrointestinal stromal tumors (GISTs), the occurrence of an epithelioid/mixed phenotype has been correlated to PDGFRA mutations, gastric localization and favorable outcome. On the other hand, the prognostic significance of an epithelioid/mixed growth pattern occasionally observed in GISTs with KIT mutation is unclear. The aim of this study was to(More)
Adenocarcinoma of the small intestine arising from heterotopic gastric mucosa is extremely rare. In this report, we present the case of a 68-year-old woman who complained of abdominal pain, weight loss and subileus. Gross examination of resected small bowel revealed multiple flat polypous lesions with cysts in the ileal submucosa, one of which containing an(More)
