Is AV fistula patency associated with angiotensin-converting enzyme (ACE) polymorphism and ACE inhibitor intake?
We suggest that pharmacological inhibition of the renin-angiotensin system is of limited value for prevention of arteriovenous fistula stenosis. Alternative strategies to prolong fistula patency should be studied.
Laparoscopic resection of colorectal cancer can achieve excellent results even in "high risk" patients and is associated with significant reductions in length of stay compared with open resection.
