Placement of self-expanding metal stents is an effective and safe definitive procedure in the palliation of malignant colorectal obstruction. In operable patients, it provides a useful option to avoid colostomy, by facilitating safer single-stage surgery.
NASH patients have a higher prevalence of small intestinal bacterial overgrowth which is associated with enhanced expression of TLR-4 and release of IL-8. SIBO may have an important role in NASH through interactions with TLR-4 and induction of the pro-inflammatory cytokine, IL-8.
Summary
Gastric antral vascular ectasia, or ‘watermelon stomach’, is a rare but important cause of gastrointestinal blood loss and anaemia, which has characteristic endoscopic and histological features. The pathogenesis of this condition remains unclear; however, many associated disorders have been documented. Various medical, surgical and endoscopic therapeutic modalities have been attempted with variable success. Leading contenders for the therapeutic modality of choice include hormonal therapy, endoscopic Nd:YAG laser and argon plasma coagulation. Randomized controlled trials to identify the ideal treatment method are lacking at present.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
