Randomized Controlled Trial Comparative Study
Randomized placebo-controlled trial on local applications of opioids after hemorrhoidectomy.
Hemorrhoidectomy is associated with considerable postoperative pain. This study assessed whether a small dose of morphine or oxycodone administered in the embedded sponge set in the anus at the end of a hemorrhoidectomy intervention reduced postoperative pain. ⋯ The local administration of very low doses of kappa-opioid agonist decreased hemorrhoidectomy postoperative pain through the interaction with specific opioid receptors located on anal mucosa.

Randomized Controlled Trial Comparative Study
Do we still need to restrict preoperative fluid administration in ambulatory anorectal surgery under spinal anaesthesia?
This study was undertaken to determine the effect of a restricted versus a standard intravenous fluid regimen on urinary retention and readiness for discharge after surgery for benign anorectal disease. ⋯ In minor anorectal surgery under spinal anaesthesia with ropivacaine, standard fluid regimen provides stable haemodynamic variables without urinary retention.
