Review Meta Analysis Comparative Study
Systematic review of perioperative selective decontamination of the digestive tract in elective gastrointestinal surgery.
Studies on selective decontamination of the digestive tract (SDD) in elective gastrointestinal surgery have shown decreased rates of postoperative infection and anastomotic leakage. However, the prophylactic use of perioperative SDD in elective gastrointestinal surgery is not generally accepted. ⋯ This systematic review and meta-analysis suggests that a combination of perioperative SDD and perioperative intravenous antibiotics in elective gastrointestinal surgery reduces the rate of postoperative infection including anastomotic leakage compared with use of intravenous antibiotics alone.

Despite advances in medical therapy, there remains no effective preventive or non-surgical therapeutic option for fibrostenotic Crohn's disease (CD). Symptomatic recurrences are common, necessitating reintervention. Intestinal fibroblasts mediate stricture formation, but their exact source is unclear. Recent evidence indicates that circulating fibrocytes drive fibrosis through differentiation into fibroblasts and the production of extracellular matrix proteins. The aim of this review is to describe current understanding of the pathophysiology underlying fibrosis in CD, the cellular and molecular biology of fibrocytes and their role in CD. ⋯ Levels of circulating fibrocytes are raised in conditions marked by exaggerated fibrosis. These and other observations prompt a characterization of fibrocyte activity in CD with a view to investigating a pathogenic role.

Half of patients with colorectal cancer develop liver metastases. There remains great variability between hospitals in rates of liver resection for colorectal cancer liver metastases (CLM). This study aimed to determine how many patients with potentially resectable CLM are not seen by specialist liver surgeons. ⋯ A considerable number of patients with potentially resectable CLM are not assessed by specialist liver teams. Improved referral rates could greatly improve resection rates for CLM, which may improve outcomes for patients with colorectal cancer.

Conventional endovascular aneurysm repair (EVAR) needs a proximal aortic seal zone that is free from aortic branch vessels. The modified application of conventional EVAR devices using adjuvant chimney or periscope grafts is described as a pragmatic alternative to custom-made fenestrated and branched endografts. This systematic review examined the application and outcomes of chimney or periscope grafts for aortic aneurysm. ⋯ These highly selected data support the potential value of chimney and periscope graft techniques for patients with challenging aortic aneurysm morphology. There is a lack of medium- and long-term follow-up data.
