Although many patients with locally advanced rectal cancer undergo restaging imaging after neoadjuvant chemoradiotherapy and before surgery, the benefit of this practice is unclear. The purpose of this study was to examine the impact of reimaging on outcomes. ⋯ Imaging restaging after neoadjuvant chemoradiotherapy in patients with locally advanced rectal cancer rarely changes treatment and does not improve survival. In a subset of patients at higher risk for worse outcome, reimaging may be beneficial.

Posttraumatic hepatic artery pseudoaneurysm is a potentially devastating complication after complex liver injury. Increasing computed tomography (CT) use may lead to more frequent identification of posttraumatic hepatic complications. This study was designed to determine the rate of hepatic pseudoaneurysm after traumatic liver injury. ⋯ The incidence of hepatic artery pseudoaneurysm increases with higher grade liver injury. Aggressive surveillance for hepatic pseudoaneurysm with interval CT-angiography 5-7 d postinjury may be warranted, especially for grade IV and V injuries.
