Peritoneal dissemination is a frequent metastatic route for cancers of the ovary and gastrointestinal tract. Tumour cells metastasize by attaching to and invading through the mesothelial cell (MC) monolayer that lines the peritoneal cavity. Metastases are influenced by carcinoma-associated fibroblasts (CAFs), a cell population that derives from different sources. Hence, we investigated whether ...

BACKGROUND Formation of intra-abdominal adhesions depends, in part, on the activity of serine proteinases. Matrix metalloproteinases (MMP) are required for epithelialization of skin wounds but their involvement in mesothelialization of peritoneal wounds and in adhesion pathogenesis is not known. Early tumor necrosis factor-alpha (TNF-alpha) levels have been proposed to reflect propensity to adh...

BACKGROUND Peritoneal dissemination is one of the main causes of death in gastric cancer patients. Transforming growth factor-beta1 (TGF-β1), one of the most potent fibrotic stimuli for mesothelial cells, may play a key role in this processing. The purpose of this study is to elucidate the effects of TGF-β1 on regulation of gastric cancer adhesion to mesothelial cells. METHODS Peritoneal tiss...

PURPOSE Here, we aimed to investigate the role of connective tissue growth factor (CTGF) in peritoneal carcinomatosis (PC) associated with colorectal cancer (CRC) and to characterize the underlying mechanism of CTGF mediating adhesion. EXPERIMENTAL DESIGN A cohort of 136 CRC patient specimens was analyzed in this study. CRC cell lines were used for in vitro adhesion assay and in vivo peritone...

Background: An incisional hernia is a bulge or protrusion that occurs near or directly along a prior abdominal surgical incision. Various surgical techniques including Open tissue repair, double breasting, darning, open and laparoscopic meshplasty have been used to repair the incisional hernias. In this era, we have selected topic ‘Pre-peritoneal versus on-lay meshplasty in incisional hernia re...

A study was designed to investigate the possibility of reducing peritoneal adhesion formation in mice by pretreatment with allopurinol. Allopurinol, at a dose of 35 mg/kg of body weight/d significantly reduced the severity of peritoneal adhesions (P < .001), and also the neutrophil response to ischemia (P < .05). Tissue myeloperoxidase activity at the site of ischemic injury was significantly l...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1217. 65 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9557-2. Peritoneal adhesions occur in up to 93% of adults after peritoneal trauma during surgery. Most adhesions are asymptomatic but can cause female ...

A surgical trauma results within minutes in exudation, platelets, and fibrin deposition. Within hours, the denuded area is covered by tissue repair cells/macrophages, starting a cascade of events. Epithelial repair starts on day 1 and is terminated by day 3. If repair is delayed by decreased fibrinolysis, local inflammation, or factors in peritoneal fluid, fibroblast growth starting on day 3 an...
