Standard dosing of enoxaparin leads to low anti-Xa levels in half of surgical ICU patients. Low levels are associated with a significant increase in the risk of DVT. These data support future studies using adjusted-dose enoxaparin.
Retrorectal tumors are most commonly benign in etiology, of a congenital nature, and have a female predominance. Complete surgical resection is the cornerstone of retrorectal tumor management. A minimal access surgery approach, when feasible, appears to be a safe option for the management of retrorectal tumors, with shorter operative time and length of stay.
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.
