Background: Endometriosis is a chronic disorder characterized by the presence of endometrial tissue outside the uterus. Endometrial cells from retrograde menstruation implant on peritoneal surfaces and elicit an inflammatory response, associated with angiogenesis, fibrosis, neuronal infiltration, and anatomical distortion. Affecting an estimated 176 million women worldwide, the condition is sti...

Accumulating evidence has indicated that mast cells can modulate a wide variety of immune responses. Migration and adhesion play a critical role in regulation of tissue mast cell function, in particular, under inflammatory conditions. We previously demonstrated that prostaglandin (PG) E(2) stimulates adhesion of a mouse mastocytoma cell line, P-815, to the Arg-Gly-Asp (RGD)-enriched matrix thro...

BACKGROUND Epithelial ovarian carcinoma is a deadly disease characterized by overt peritoneal metastasis. Individual cells and multicellular aggregates, or spheroids, seed these metastases, both commonly found in ascites. Mechanisms that foster spheroid attachment to the peritoneal tissues preceding formation of secondary lesions are largely unknown. METHODS Cell culture models of SKOV-3, OVC...

BACKGROUND AND OBJECTIVES We present a case of small bowel volvulus around an endotack applied during total extraperitoneal laparoscopic hernia repair (TEP). This complication prompts reconsideration of the role of tacks during extraperitoneal laparoscopic hernia repairs. METHODS We undertook a chart review and provide a case presentation with review of the literature. RESULT A 66-year-old ...

We have read the debate on peritoneal closure by Cheong et al. with interest (Cheong et al., 2001). The authors state that the long term benefits and hazards of non-closure of the peritoneum are unknown, and expect adhesion related problems. Among the various outcome measures concerning long-term morbidity, adhesion formation/reformation is probably one of the most important ones. The presence ...

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 ...

OBJECTIVE Peritoneal adhesions are almost ubiquitous following surgery. Peritoneal adhesions can lead to bowel obstruction, digestive problems, infertility, and pain, resulting in many hospital readmissions. Many approaches have been used to prevent or treat adhesions, but none offer reliable results. A method that consistently prevented or treated adhesions would benefit many patients. We hypo...

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 Intra-abdominal surgical intervention can cause the development of intra-peritoneal adhesions. To reduce this problem, different agents have been tested to minimize abdominal adhesions; however, the optimal adhesion prophylaxis has not been found so far. Therefore, the A-Part(®) Gel was developed as a barrier to diminish postsurgical adhesions; the aim of this randomized controlled s...
