Multicenter Study Observational Study
Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study.
This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. ⋯ There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Randomized Controlled Trial
Perianal block with ropivacaine as a supplement to anaesthesia in proctological surgery: double-blind randomized placebo-controlled trial (PERCEPT).
The benefit of a perianal block as an adjunct to general or regional anaesthesia is debated. This RCT aimed to compare pain at 24 h and up to 14 days after proctological surgery in patients with and without a perianal block. ⋯ Perianal block as an adjunct to general or regional anaesthesia should be recommended for proctological surgery. It yields a reduction in pain, a reduced need for opioids, and a faster recovery with minimal risk of adverse events. Registration number: NCT03405922 ( http://www.clinicaltrials.gov).
