Methylene blue for pain after hemorrhoid surgery
Treatments studied
Part of Digestive system clinical trials.
This trial tests whether injecting methylene blue (a dye) into the area around the anus during hemorrhoid surgery can reduce pain after the operation. If you are having Milligan-Morgan surgery for mixed hemorrhoids, this study may help find a way to make your recovery more comfortable.
