MRI test before surgery for early cervical cancer spread risk
This trial studies whether a special MRI scan can better predict whether early cervical cancer has spread into tiny lymph and blood vessels (lymphovascular space invasion) before surgery. If it works, it may help doctors plan the best treatment after surgery.

Using 68Ga-FAPI PET/CT scan for thyroid cancer lymph nodes
This study uses a special type of PET/CT scan (68Ga-FAPI) to see how well it finds cancer spread in lymph nodes before thyroid cancer surgery. It may help doctors plan your treatment more accurately.

Elacestrant for premenopausal women with early breast cancer
This trial tests a new hormone therapy pill, elacestrant, given alone or with another drug to suppress ovarian function before surgery. It's for premenopausal women with early-stage, hormone receptor-positive, HER2-negative breast cancer to see if it can shrink the tumor.
VillejuifAges 18 years+ - NCT07551375Recruiting
Fast MRI scan to diagnose gallbladder inflammation
This study tests whether a new type of quick MRI scan can reliably detect acute cholecystitis—sudden inflammation of the gallbladder. If it works well, doctors may be able to diagnose this condition faster and help patients get treatment sooner.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07243106Enrolling by invitation
Ultrasound vs physical exam for predicting difficult airway
This trial compares using ultrasound of the airway versus standard physical exams to predict if placing a breathing tube will be difficult. It's for adults having elective surgery with a breathing tube.
Tokat Province, Tokat ProvinceAges 18–60 - NCT06810232Enrolling by invitation
Health factors and longer hospital stay after endoscopy
This study looks at how general health factors (like age and other medical conditions) might affect how long you need to stay in the hospital after a routine stomach or bowel exam called an endoscopy. The goal is to understand which patients may need extra care so hospitals can plan better.
IstanbulAges 18 years+ - NCT07549113Recruiting
Preoperative prep methods for large abdominal wall hernias
This trial compares different ways to prepare your body before surgery to repair a large hernia (bulge in your abdominal wall). The goal is to find the best approach to help you heal well after surgery.
Krasnodar, Krasnodarskiy KrayAges 18 years+ - NCT06543615Enrolling by invitation
Ultrasound stomach check before surgery in sleeve gastrectomy patients
This study uses ultrasound to measure how much stomach content remains after fasting in people who have had sleeve gastrectomy surgery. It aims to understand if the standard 8-hour fasting period is enough for this group before other surgeries.
Cairo, Cairo GovernorateAges 21–45 - NCT06794697Recruiting
Does admission day affect anxiety before heart surgery?
This study looks at whether the day you are admitted to the hospital for planned heart surgery affects your anxiety levels before the operation. The goal is to help hospitals schedule admissions in a way that lowers stress for patients.
RennesAges 18 years+ - NCT06748690Recruiting
Comparing biopsy methods for stomach tumors
This trial compares two ways to take a tissue sample from stomach tumors before surgery to see which works better. The results may help doctors choose the best method for patients.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06023069Recruiting
Walking test before surgery and recovery after
This study checks how well you can walk before your planned surgery and whether that affects how quickly you recover afterward.
StockholmAges 18 years+ - NCT06716892Recruiting
Non-invasive imaging for head and neck tumors
This trial is testing a new, non-invasive imaging technique called MSOT to look at head and neck tumors. It compares images from people with tumors to healthy volunteers, aiming to improve how doctors evaluate tissue before surgery.
Erlangen, BavariaAges 18 years+ - NCT07414251Recruiting
Preparing children for heart procedures
This study looks at how children prepare for heart surgery or a heart catheterization. It will ask families to fill out questionnaires to help improve preoperative care.
Berlin, State of BerlinAges Up to 18 years - NCT07435805Recruiting
Long-term COVID effects in patients preparing for surgery
This study looks at long-term health effects in people who had COVID-19 and are now preparing for surgery. If you had a lab-confirmed COVID-19 infection, you may be asked to fill out a questionnaire during your preoperative anesthesia visit to help researchers understand how COVID affects recovery and health over time.
Elâzığ, ElaziğAges 18 years+ - NCT07581691Recruiting
Ultrasound Stomach Checks Before Surgery in Children
This study tests whether ultrasound scans of the stomach before surgery help keep children safe during anesthesia. Researchers will measure how full the stomach is to make sure children are ready for surgery.
KayseriAges birth–18 years - NCT05092126Recruiting
Testing a pre-surgery breathing and heart check tool
This study is developing and checking how well a pre-surgery evaluation system (using objective body measurements) can predict and help around the time of anesthesia and surgery. You might be asked to complete a clinic screening and provide consent, as long as your results fit their safety and screening thresholds.
Durham, North CarolinaAges 18 years+ - NCT05774678RecruitingPhase 3
Pre-surgery radiation options for invasive breast cancer
This trial compares two schedules of radiation given before mastectomy to see which works better for invasive breast cancer, followed by immediate breast reconstruction. It also studies tiny “biomarker” signals in tissue to learn why one radiation approach may help more.
Houston, TexasAges 18 years+ - NCT07007494Recruiting
Early outcomes and nutrition after weight loss surgery
This study looks at how well patients recover after laparoscopic sleeve gastrectomy and how nutritional scores relate to their early outcomes. It may help doctors improve care for people having this common weight loss surgery.

Common questions
- Are there clinical trials for preoperative evaluation?
- Yes. Clin2 currently lists 31 recruiting preoperative evaluation 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 preoperative evaluation 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 preoperative evaluation 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.
