HEMORRHOIDS

This study compares a new minimally invasive treatment called superior rectal artery embolization (SRAE) to standard procedures for controlling bleeding from hemorrhoids. About 80 adults with grade I-III hemorrhoids and significant bleeding will be randomly assigned to SRAE or st…

This study tests if an ultrasound-guided nerve block near the tailbone can control pain during hemorrhoid surgery as well as a standard spinal block. Fifty adults having hemorrhoid removal will be randomly assigned to one of the two methods. Researchers will measure pain scores a…

This study tests whether giving ketamine during hemorrhoid removal surgery can reduce pain and the need for narcotic painkillers afterward. About 100 adults with severe hemorrhoids will be randomly assigned to receive ketamine or not while under anesthesia. The main goal is to se…

This study compares two types of nerve blocks to control pain after hemorrhoid surgery. About 64 adults will receive either a pudendal block or a sacral ESP block. The goal is to see which one provides better pain relief and helps people recover faster.

This study tests a procedure that blocks blood flow to hemorrhoids using a small tube inserted through the wrist. It aims to reduce bleeding and other symptoms without the need for surgery. Twenty adults with grade II-IV hemorrhoids will be treated and followed for 24 months to c…

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 looks at whether people with hemorrhoids are more likely to 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 simply to …
