Laparoscopic surgery

This trial asks whether routinely identifying and freeing the ureters before cutting uterine vessels during laparoscopic hysterectomy reduces the chance of ureter injury compared with doing so only when specific problems arise. It will include thousands of women having the surger…

This study will test a new mesh implant called ProGYNious for repairing pelvic organ prolapse in 100 women. The goal is to see how well it works and if it is safe. Participants will be followed for complications and quality of life after surgery.

This study compares three ways to remove carbon dioxide gas left in the belly after laparoscopic surgery to see which one reduces pain the most. 150 adults having non-emergency laparoscopic surgery will be randomly assigned to active gas removal, breathing maneuvers, or no extra …

This study compares two painkillers—tegileridine and sufentanil—given as a single shot after laparoscopic surgery in people at high risk of postoperative nausea and vomiting (PONV). The goal is to see if tegileridine, a newer opioid designed to cause fewer side effects, can provi…

This study looks at whether adding a special carbon dioxide monitor through the nose can reduce dangerous drops in oxygen levels in elderly patients (ages 65-80) waking up from anesthesia after laparoscopic abdominal surgery. About 324 participants will be randomly assigned to st…

This study tests whether giving lidocaine through a vein during surgery, plus injecting ropivacaine into the surgical cuts, helps people recover better after laparoscopic colon cancer surgery. About 182 adults will be randomly assigned to get either the lidocaine plus ropivacaine…

This study will develop a machine learning model to predict which patients are at risk of hypothermia (low body temperature) during gynecological laparoscopic surgery. Researchers will collect data from 1,000 female patients before surgery to identify high-risk individuals. The g…
