Memphis, TennesseeAges Any age - NCT05304286Recruiting
Study of brain and pain in long-lasting post-surgery pain
This trial studies what’s happening in the brain and how pain is processed in people with pain that lasts long after surgery. It may help researchers understand chronic post-surgical pain and find better ways to treat it.
Boston, MassachusettsAges 12 years+ - NCT05421650Recruiting
Surgery to remove pelvic lymph node spread in cervical cancer
This trial studies whether surgically removing cancerous pelvic or nearby lymph nodes before or as part of standard treatment improves outcomes for women with certain cervical cancers. It focuses on people whose scans suggest lymph node metastasis can be safely removed.
BengaluruAges 20–70 - NCT05433467Recruiting
CT-guided locating for tiny liver cancer before surgery
This study tests a CT-guided method to find and precisely locate very small liver cancer spots before surgery. It may help surgeons remove the tumor more accurately when standard scans cannot clearly see it.
Yangzhou, JiangsuAges 18 years+ - NCT05434819Recruiting
Ablation study during heart surgery for atrial fibrillation
This trial looks at whether a special heart rhythm treatment called “ablation” works well when done during certain heart operations. It may help reduce atrial fibrillation (AF) symptoms or future abnormal rhythm episodes for people who are already having surgery.
Hamilton, OntarioAges 18 years+ - NCT05460793Recruiting
Surgery timing trial for brain bleeding after a stroke
This trial looks at whether starting brain surgery within 8 hours after a type of stroke called intracerebral hemorrhage (bleeding in the brain) can improve outcomes. It’s for adults with a certain amount and location of bleeding and without common causes like an aneurysm or malformation.
AmsterdamAges 18 years+ - NCT05502523Recruiting
Blood test DNA levels after lung surgery
This study looks at how different lung surgical techniques affect levels of tumor DNA in the blood before and after surgery for early-stage lung cancer. It may help doctors choose surgical approaches and use a blood test to monitor cancer after surgery.
Abington, PennsylvaniaAges 18 years+ - NCT05543941Recruiting
Test advanced irrigation during knee, hip, or shoulder replacement
This trial studies a cleaning solution used during surgery to lower the risk of complications and improve outcomes after joint replacement. It may be an option if you’re having a planned knee, hip, or humerus (shoulder) replacement and meet the specific health and allergy requirements.
Vancouver, British ColumbiaAges 18 years+ - NCT05561907Recruiting
Endoscopic vs. surgical bypass for stomach blockage from cancer
This trial compares two ways to bypass a blockage in your stomach caused by cancer near the pancreas or duodenum. Both approaches create a new connection so food can pass through, but one uses a camera-guided tube (endoscopic) and the other is surgical. The study will see which works better for your symptoms and quality of life.
New Brunswick, New JerseyAges 18 years+ - NCT05565118RecruitingPhase 1
Brain activity study during surgery for high-grade glioma
This early-stage study measures electrical brain activity during brain tumor surgery to see if it can predict tumor return or progression. You may be offered the additional measurements while your surgeon removes a suspected or known high-grade glioma.
Cleveland, OhioAges 18 years+ - NCT05600569Recruiting
Thoracic surgery registry study in Spain
This is a registry (a secure log) that collects information about patients who undergo thoracic (chest) surgery. It helps researchers understand what surgeries are being done and may improve planning and care over time.
ZaragozaAges Any age - NCT05652361Recruiting
AI guidance system for robotic rectal cancer surgery
This trial tests a machine-learning (AI) system that may help guide surgeons during robotic rectal cancer operations. It’s meant to support safer, more accurate surgery while comparing outcomes to standard surgical guidance.
Dresden, SaxonyAges 18 years+ - NCT05713149Recruiting
Treating pressure sores with surgery and anti-bacterial medicines
This study looks at whether combining a surgical skin flap with anti-bacterial treatment can improve pressure sores that are complicated by bone infection (osteomyelitis). It targets adults who have nerve/movement problems that put them at high risk for these sores.
GarchesAges 18 years+ - NCT05877300RecruitingPhase 1
Test a new esophagus implant to rebuild a short esophagus segment
This Phase 1 study tests the safety and feasibility of a new esophagus implant for people who need only a short (about 6 cm or less) section of their esophagus rebuilt after serious injury or scarring. If it does not work, you must be willing to have a planned “rescue” surgery later.
Los Angeles, CaliforniaAges 18 years+ - NCT05899933Recruiting
Compare two surgical treatments for peri-implantitis
This study compares two different surgical approaches to treat peri-implantitis, an infection/inflammation around dental implants. You may be enrolled because you have a qualifying implant and meet health and medication requirements.
AthensAges 18–80 - NCT05906810Recruiting
Treating gum inflammation around implants to improve blood vessel function
