This study tests a new surgical method for removing non-cancerous or early cancerous growths (submucosal tumors) located where the stomach meets the esophagus. The technique combines two types of scopes (laparoscope and endoscope) with a special step to prepare the blood vessels …

This study compares two surgical methods for treating pelvic organ prolapse, a condition where pelvic organs drop from their normal position. Researchers will randomly assign 86 women to receive either laparoscopic lateral suspension (a keyhole surgery) or transvaginal sacrospino…

This study tests a new AI tool called GAPS-Agent that helps doctors plan surgeries for lung cancer. The tool is designed to assist less experienced doctors in making complex decisions. Researchers will compare AI-generated plans to those from a standard AI, and expert surgeons wi…

This study looks at stored tissue samples from 100 people with advanced osteosarcoma to check for loss of the MTAP protein. Researchers want to see how common this loss is and whether it relates to cancer spread or immune system activity. No new treatment is given; the goal is to…

This study involves 320 adults with advanced rectal cancer who received standard chemoradiotherapy and surgery. Researchers are building a computer model that uses MRI scans and patient data to predict whether the cancer has completely disappeared after treatment. The goal is to …

This study explores whether a simple breathing test done before surgery can help predict when a patient's oxygen levels might drop dangerously low during lung surgery. Researchers will measure how air moves through the lungs while patients breathe normally, then track oxygen leve…

This study looks back at 193 people with stomach, appendix, or colon cancer who had surgery with or without heated chemotherapy (HIPEC). Researchers want to see if HIPEC affects how quickly the bowels start working again after surgery and whether it leads to more complications. T…
