Background: Perianal surgeries have been associated with considerable postoperative pain and discomfort. Perianal intradermal injection of methylene blue has been shown to ablate perianal nerve endings and bring about temporary pain relief.

The primary outcome measure was pain score and analgesic use. Secondary outcomes were complications. Results: There were 25 patients in the methylene blue ar.. Read More»
