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 - NCT07695649Recruiting
Minimally invasive surgery for grade 3 hemorrhoids
This study tests a less invasive surgery for severe hemorrhoids (grades 3 and 4). If you have not had hemorrhoid surgery before and do not have other anal problems, you may be able to join.
Palma de MallorcaAges 18 years+ - NCT07534761Recruiting
Minimally Invasive Surgery for Severe Hemorrhoids
This trial tests a minimally invasive surgical approach for severe internal hemorrhoids (Grade III or IV). The goal is to help patients with significant hemorrhoid symptoms who need surgery, using techniques that may cause less pain and faster recovery than traditional methods.
Palma, Balearic IslandsAges 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.
AthensAges 18 years+ - 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+ - 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 - 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 - 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 - 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+ - NCT06660680Enrolling by invitationPhase 3
Methylene blue for pain after hemorrhoid surgery
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.
Hefei, AnhuiAges 18–75 - 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+ - NCT04248205RecruitingPhase 4
Ketamine to reduce pain after hemorrhoid surgery

Common questions
- Are there clinical trials for hemorrhoids?
- Yes. Clin2 currently lists 37 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.
