AI analysis of CT scans for lung health before chest surgery
This study uses a computer program (deep learning) to analyze your chest CT scan and lung function test results before surgery. The goal is to see if the AI can help doctors better assess your lungs and plan your operation.
Guangzhou, GuangdongAges 18–75 - NCT07660679Recruiting
Carotid ultrasound before liver transplant surgery
This study looks at whether measuring the thickness of the carotid artery (the main artery in the neck) before a planned liver transplant can help doctors predict and manage blood flow changes during surgery. It may help patients get safer care during their transplant.
DiyarbakırAges 18 years+ - NCT06894797Recruiting
Chemo and radiation before and after surgery for rectal cancer
This study tests a sequence of chemotherapy and radiation before and after surgery for rectal cancer. It compares giving more chemo between the end of radiation and surgery (consolidation) versus giving some chemo before radiation starts (induction). The goal is to see which order works better.
BeijingAges 18–75 - NCT06808022Enrolling by invitation

Numbing Block to Reduce Pain Medicine During Nose Surgery
This study tests whether a special numbing injection in the upper jaw (bilateral maxillary block) helps reduce the amount of pain medication needed during septorhinoplasty—a surgery to reshape the nose and straighten the septum. The goal is to find ways to use less strong pain medication during surgery.
Yenimahalle, AnkaraAges 18–65 - NCT07628205Enrolling by invitationPhase 2
Botulinum Toxin to Help Close Large Belly Wall Hernias
This study tests whether injecting botulinum toxin (Botox) before surgery can help close large holes in the belly wall by relaxing the muscles and making it easier to bring the edges together. This might reduce complications and improve healing after surgery.
Legnano, MilanoAges 18 years+ - NCT07192978Recruiting

- How do I know if I qualify for a preoperative 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 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.
