Recruiting studies
- NCT04187261Recruiting
Audit of surgical care for hip fractures
This trial is an audit, meaning researchers review existing hospital records to understand what happens after hip fractures are treated with surgery. It may help improve how hip fracture care is documented and delivered at their hospital.
Karachi, SindhAges 1–100 - NCT04192825Recruiting

This trial studies different care and management approaches for people with Crohn’s disease who have an anal infection or drainage area and are planning a drainage procedure. It may help improve how care is planned around the drainage procedure and follow-up.
RennesAges 18 years+ - NCT04219956Recruiting
Low-sugar diet aims to reduce belly-surgery pain
This study tests whether a special diet low in polyamines (a food-related substance) can reduce pain after major abdominal surgery. It compares pain control while you use a patient-controlled morphine pump or take opioid tablets by mouth after surgery.
BrestAges 18 years+ - NCT04235764Recruiting
Testing a new bladder-tumor surgery tool for removed tissue
This trial studies a redesigned surgical instrument used during bladder tumor removal, to see if it can improve how the removed tissue samples are collected. It may help future patients by supporting better study of bladder tissue during cancer care.
Bethesda, MarylandAges 18–120 - NCT04268849RecruitingPhase 3
IV vs oral iron after weight-loss surgery
This Phase 3 study compares taking iron through an IV versus by mouth to treat iron-deficiency anemia after Roux-en-Y gastric bypass or sleeve gastrectomy. The goal is to see which method works better and is safer for improving iron levels and blood counts.
Baltimore, MarylandAges 18 years+ - NCT04319848RecruitingPhase 1
Tissue-engineered cornea transplant for specific eye swelling conditions
This Phase 1 trial tests a new, lab-made tissue transplant to improve corneal clarity in people with certain types of corneal endothelium failure (eye swelling) caused by specific conditions. The main goal is to check safety and see if vision and corneal health improve.
SingaporeAges 21–80 - NCT04330846Recruiting
Study of new narrowing in Crohn’s treated with two approaches
This study looks at treatments for a new (de novo) narrow area in the bowel from Crohn’s disease. It aims to see which treatment works better at relieving blockage-type symptoms for the safest, most effective option.
Badalona, BarcelonaAges 18–80 - NCT04373655Recruiting
Lymph node surgery after chemotherapy for invasive breast cancer
This trial studies how doctors should operate on lymph nodes after you finish chemotherapy given before surgery. It may help improve treatment planning for people whose breast cancer has spread to nearby lymph nodes, but not to distant organs.
Esslingen am NeckarAges 18 years+ - NCT04431024Recruiting
Testing imaging and biopsy options for people with BAP1 risk
This study looks at how well advanced scans, liquid biopsy tests, and small follow-up procedures can find early mesothelioma in people with a high-risk BAP1 gene condition. It may help catch cancer earlier when treatment could work better.
Bethesda, MarylandAges 30–120 - NCT04451278Recruiting
Brain scan study to predict outcomes after epilepsy surgery in kids
This trial uses resting-state brain MRI (a scan while you’re not doing a task) to help predict how well children with hard-to-treat epilepsy may do after surgery. If you qualify, you would help researchers see whether the scan can forecast prognosis.
Paris, PARISAges 6–18 - NCT04455282Recruiting
Blood test-guided surgery for gastroesophageal cancer
This trial studies blood-based biomarkers to help doctors choose the best individualized surgical treatment for gastroesophageal junction adenocarcinoma. If you qualify, you’ll get standard care plus additional testing to see whether the blood results can guide surgery more precisely.
Cologne, North Rhine-WestphaliaAges 18 years+ - NCT04493996Recruiting
Cognitive training before heart surgery to protect memory
This trial tests whether brain-focused cognitive training before elective heart surgery can help reduce memory and thinking problems afterward. If you qualify, you may do language-based thinking exercises and complete short brain tests around the time of surgery.
Bad NauheimAges 18 years+ - NCT04498221Recruiting
Mapping lymph flow in oropharyngeal cancer with scans
This study uses a special dye or tracer to map how lymph fluid travels from an oropharyngeal (throat) cancer to nearby lymph nodes. It may help doctors understand the most likely spread pattern and plan future treatment more accurately.
LondonAges 18 years+ - NCT04506008RecruitingPhase 2
Radiation followed by surgery for soft tissue sarcoma
This trial tests a treatment plan where you first get a shorter (hypofractionated) course of radiation and then have surgery to remove the tumor. It may help control the cancer locally in certain soft tissue sarcomas and improve surgical outcomes.
Nashville, TennesseeAges 18 years+ - NCT04515459RecruitingPhase 2
Pre-surgery exercise and care program for limb sarcoma
This Phase 2 trial tests a “prehabilitation” program done before surgery to help people with arm or leg (limb) sarcoma be better prepared for their operation. It may help improve how well patients tolerate treatment and recover by planning supportive care around the weeks before surgery.
ToulouseAges 16 years+ - NCT04527705Recruiting
Testing endodontic retreatment in one versus two visits
This study compares doing tooth root-canal retreatment in one visit versus two visits. It’s meant to see which approach leads to better outcomes for teeth with infection at the root tip (apical periodontitis).
Sant Cugat del Vallès, BarcelonaAges 18–75 - NCT04552145Recruiting
Physical therapy versus surgery for lumbar spinal stenosis
This study compares physical therapy to surgery to help relieve symptoms from narrowing in the lower spine. It looks at which treatment works best for walking discomfort caused by spinal stenosis.
LillehammerAges 50–80 - NCT04570553Recruiting
Testing a tool during surgery for early endometrial cancer
This study looks at how well a surgical tool is used during standard surgery for early endometrial cancer, and whether it relates to test results from fluid taken in the abdomen. It may help surgeons improve how samples are collected and interpreted during routine care.
York, PennsylvaniaAges 18 years+ - NCT04578301Recruiting
Predicting who develops serious liver worsening after surgery
This study looks at your liver health before and after surgery to predict the risk of “acute-on-chronic liver failure,” which means a sudden worsening of liver function on top of an existing liver condition. If you qualify, your doctors may use study data to better identify who needs closer monitoring after surgery.
BonnAges 18 years+ - NCT04606030Recruiting
Tested lymph surgery for breast-cancer–related arm swelling
This trial studies a specialized lymph surgery (called VLNT, moving lymph tissue) to treat swelling in an arm caused by breast cancer treatment. It may help reduce lymphedema that doesn’t fully improve with compression and elevation.
Chicago, IllinoisAges 18–75 - NCT04623502Recruiting
Study of kidney and bladder cancer metabolism during surgery
This study looks at how kidney and bladder (urothelial) tumors use fuel by taking samples during surgery or biopsy. It may help researchers learn what drives these cancers and guide better future treatments.
Dallas, TexasAges 18 years+ - NCT04635657Recruiting
Testing brain function after meningioma surgery
This study measures how thinking and memory change after surgery to remove a meningioma near the front or side of the brain. It may help doctors better understand what to expect and how cognitive recovery can differ from person to person.
Columbus, OhioAges 18–89 - NCT04638790RecruitingPhase 3
First treatment chemotherapy study for newly diagnosed Hodgkin lymphoma

Common questions
- Are there clinical trials for surgical?
- Yes. Clin2 currently lists 1,195 recruiting surgical 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 surgical 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 surgical 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.
