Artery Blocking vs Rubber Bands for Internal Hemorrhoids
This trial compares two treatment methods for internal hemorrhoids that haven't improved with diet, fiber, or creams. One method blocks blood flow to the hemorrhoids using a catheter (a thin tube); the other uses rubber bands to cut off blood supply. Both are minimally invasive procedures.

PET Imaging Scan for Detecting Cancer Using New Radioactive Tracer
This study tests a new type of imaging scan (PET/CT or PET/MR) that uses a radioactive tracer to help doctors better detect and diagnose various cancers. The scan targets a specific protein found in tumors, which may help identify cancer more accurately than standard imaging.

Chemotherapy, radiation, and immunotherapy for anal cancer
This study tests a combination of chemotherapy, radiation therapy, and an immunotherapy drug (anti-PD-1 antibody) for anal squamous cell cancer. The trial enrolls patients at different stages of disease to see if adding immunotherapy improves outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07556718RecruitingPhase 2
Amitriptyline for IBS-like Symptoms in Stable Crohn's Disease
This study tests whether a medication called amitriptyline can help reduce belly pain and bowel problems in people whose Crohn's disease is well-controlled. Amitriptyline is an older antidepressant that may help with pain and bowel symptoms even when inflammation is quiet.
Ann Arbor, MichiganAges 18–65 - NCT07557173Recruiting
Better Bowel Prep for Repeat Colonoscopy After Failed Cleaning
This trial tests three different bowel-cleaning preparations for patients who need a repeat colonoscopy because their bowel wasn't clean enough the first time. The goal is to find which preparation works best to get your colon ready for a successful second procedure.
BeneventoAges 18 years+ - NCT07552402Recruiting
Oral Paclitaxel Plus Fruquintinib for Advanced Stomach Cancer
This trial tests a combination of two oral drugs (paclitaxel and fruquintinib) for advanced stomach cancer that has already been treated with one round of chemotherapy. The goal is to see if this combination helps control the cancer better than other standard second-line treatments.
Shijiazhuang, HebeiAges 18–75 - NCT07553143Recruiting
Melatonin before gallbladder removal surgery
This study tests whether taking melatonin (a natural sleep hormone) before elective gallbladder removal surgery helps patients recover better and feel less pain or discomfort afterward. Melatonin may help reduce stress on the body during surgery.
Dhaka, Dhaka DivisionAges 18–60 - NCT07558083RecruitingPhase 3
Tracking colorectal cancer response using blood tests
This study tests whether a simple blood test can track how well your colorectal cancer is responding to first-line chemotherapy. By monitoring cancer markers in your blood, doctors may be able to detect treatment changes earlier than traditional imaging.
Mechelen, AntwerpenAges 18 years+ - NCT07558447Recruiting
Studying Tiny Particles to Predict Chemotherapy Nerve Damage
This study looks at tiny particles in your blood to understand and potentially predict nerve damage caused by certain chemotherapy drugs. Researchers will monitor you before, during, and after your cancer treatment to see if these particles can help warn doctors about this common side effect.
MilanAges 18 years+ - NCT07557251RecruitingPhase 1
Combination immunotherapy for advanced liver cancer with hepatitis B
This trial tests a new combination of three drugs (BRII-5395, sintilimab, and bevacizumab) for advanced hepatocellular carcinoma (liver cancer) in patients with hepatitis B who have not responded well to previous treatments. The goal is to evaluate whether this combination is safe and effective.
BeijingAges 18–70 - NCT07558304Recruiting
Comparing two stent placements for bile duct blockage from cancer
This trial compares two ways of placing a metal stent to open a blocked bile duct caused by cancer. The goal is to see which method works better and has fewer complications.
Porto Alegre, Rio Grande do SulAges 18 years+ - NCT07559578Recruiting
Colostomy Care Training for Nursing Students

Minimally invasive reflux surgery for Asian patients with severe heartburn
This trial tests a newer, less invasive surgical procedure called TIF (Transoral Incisional Fundoplication) for patients with severe acid reflux and regurgitation that hasn't improved with high-dose medications. The procedure is done through the mouth rather than the abdomen, and researchers will follow patients for 5 years to see if it works and is safe in Asian populations.

Using MRI to study blood flow before TIPS in cirrhosis
This study uses an advanced MRI technique (called 4D-flow) to look at blood flow in the liver before and after a TIPS procedure (a small tube that helps lower blood pressure in the liver). The goal is to better understand how TIPS affects blood flow and outcomes, which may help improve care for people with cirrhosis.
