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).

Conditional survival accounts for the time already survived after surgery and may be of additional informative value. The aim was to assess conditional survival in patients with oesophageal cancer and to create a nomogram predicting the conditional probability of survival after oesophagectomy. ⋯ The probability of achieving 5-year overall survival after oesophagectomy for cancer increases with each additional year survived. The proposed nomogram predicts survival in patients after oesophagectomy, taking the years already survived into account.
