Recruiting studies
- NCT03972956Recruiting
Collecting samples during cancer or surgery visits
This trial looks at collecting (taking) medical samples from people who need surgery for colorectal cancer, stomach (gastric) cancer, or a non-cancer condition. It may help researchers better understand these diseases and improve how treatment is planned.
Wuhan, HubeiAges 18–80 - NCT04248205RecruitingPhase 4
Ketamine to reduce pain after hemorrhoid surgery
This trial tests whether ketamine can lessen pain after hemorrhoidectomy (surgery for severe hemorrhoids). It may help reduce how much pain medicine you need during recovery.
Oklahoma City, OklahomaAges 18–100 - NCT06175325Recruiting
Embolization for hemorrhoids: a procedure without surgery
This trial tests a minimally invasive procedure called embolization (blocking the blood supply) to treat hemorrhoids that bleed or come back. It may be a good option if you want to avoid surgery.
Stoke-on-TrentAges 18 years+ - NCT06798155Recruiting
Music to prevent pain after anal surgery
This study tests whether listening to a specific set of music before and after surgery for hemorrhoids, fistula, or anal fissure can help reduce pain. You would use a phone or tablet app to listen to short music sessions.
Saint-DenisAges 18 years+ - NCT06969274Recruiting
Nerve Block vs. Spinal Block for Hemorrhoid Surgery
This study compares two ways to numb the area for hemorrhoid surgery: an ultrasound-guided nerve block near the tailbone (sacral erector spinae plane block) versus a traditional spinal 'saddle block.' The goal is to see which provides better pain relief and fewer side effects.
CairoAges 18–65 - NCT07026513Recruiting
Aminaphtone and lidocaine spray for hemorrhoids
This trial tests a medication called aminaphtone taken by mouth, combined with a lidocaine spray, to treat painful internal hemorrhoids. It may help reduce symptoms without surgery.
TrevisoAges 18–85 - NCT07159334Recruiting
Lidocaine vs Nitroglycerin for Pain After Hemorrhoid Surgery
This study compares a lidocaine ointment versus a nitroglycerin (GTN) ointment for pain relief after hemorrhoid removal surgery. It aims to see which works better for patients with advanced hemorrhoids.
Lahore, Punjab ProvinceAges 18–60 - NCT07399860RecruitingPhase 2
Botox before hemorrhoid surgery to reduce pain after surgery
This trial tests whether injecting botulinum toxin (Botox) into the anal muscle before hemorrhoid removal surgery can lower pain after the operation. It is for people with advanced hemorrhoids that have not gotten better with other treatments and who are already planning to have surgery.
Moscow, MoscowAges 18 years+ - NCT07404774Recruiting
stitch and laser treatment for hemorrhoids
This trial is testing a combined treatment for hemorrhoids that are causing symptoms. It uses a technique to stitch the hemorrhoid tissue back in place (suture mucopexy) plus a laser to shrink blood vessels. The goal is to see if this approach works well for people with grades II, III, or IV hemorrhoids, even if they've had other treatments before.

Common questions
- Are there clinical trials for hemorrhoids?
- Yes. Clin2 currently lists 33 recruiting hemorrhoids studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a hemorrhoids trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a hemorrhoids trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
