HEMORRHOIDS

This study compares a new minimally invasive treatment called superior rectal arterial embolization (SRAE) to standard procedures for controlling bleeding from hemorrhoids. SRAE blocks the blood supply to hemorrhoids without cutting or damaging the anal area. The trial will enrol…

This study tests a new, less invasive way to treat bleeding hemorrhoids by blocking the artery that supplies them. It involves a small tube inserted through the wrist, done as a day case under local anesthetic. Twenty adults with grade II-IV hemorrhoids who prefer not to have sur…

This study tests whether a single dose of ketamine given during hemorrhoid surgery can lower pain and reduce the number of opioid pain pills needed afterward. About 100 adults with severe hemorrhoids will take part. Participants are asleep during the procedure and won't know if t…

This study tests whether injecting botulinum toxin (Botox) into the anal muscle one week before hemorrhoid surgery can lower pain after the operation. About 292 adults with severe hemorrhoids will receive either Botox or a placebo injection. Researchers will track pain levels, pa…

This study tests a newer numbing technique called a sacral block against a standard saddle block for pain relief during hemorrhoid surgery. About 50 adults will be randomly assigned to one of the two methods. The main goal is to see how well each controls pain in the first 24 hou…

This study compares two types of pain blocks for adults having hemorrhoid surgery. The goal is to see which block provides better pain control and helps people recover faster. About 64 participants will be enrolled.

This study aims to find out if people with hemorrhoids are more likely to also have varicose veins in their legs. Researchers will use ultrasound to check the leg veins of 400 adults—half with hemorrhoids and half without. No treatments or medications are involved; the goal is si…
