Fecal Microbiota Transplantation for the Treatment of Refractory Hepatic Encephalopathy After TIPS Surgery
This is a single-center, prospective, open-label, parallel-group exploratory clinical study designed to evaluate the safety and preliminary efficacy of fecal microbiota transplantation combined with standard medical therapy in patients with refractory overt hepatic encephalopathy after transjugular intrahepatic portosystemic shunt. The study also aims to explore whether adjunctive prebiotic supplementation may …
External Oblique Intercostal Plane Block for Postoperative Analgesia After Major Upper Abdominal Surgery
Postoperative pain after laparoscopic major upper abdominal surgery (e.g., gastric, hepatic, gallbladder, pancreatic surgery) is often severe, and inadequate analgesia may lead to increased opioid use, opioid dependence, and poor functional recovery. Current analgesic techniques such as neuraxial block have safety concerns (e.g., hypotension, neurological injury), while transversus abdominis plane …
Comparison of Vacuum-Assisted and Conventional Ureteral Access Sheath in Retrograde Intrarenal Surgery
This study aims to compare the efficacy and safety, the ratio of stone-free rates, and complications of two types of access sheaths used in retrograde intrarenal surgery to treat upper urothelial stones. The access sheath types are those with vacuum aspiration and the conventional ones.
Transcutaneous Electrical Nerve Stimulation for Acute Postoperative Pain After Video-Assisted Thoracoscopic Surgery
This randomized, double-blind, sham-controlled study aims to evaluate the effects of transcutaneous electrical nerve stimulation (TENS) on acute postoperative pain, sleep quality, and quality of life in patients undergoing video-assisted thoracoscopic surgery (VATS). Participants will be randomly assigned to either an active TENS group or a sham TENS group. TENS …
Connectome-guided Onco-functional Resection With Tractography-Extended Neuronavigation in Brain Tumor Surgery
Brain tumor surgery in so-called "eloquent" brain areas aims to remove as much tumor as possible while preserving neurological functions. Standard surgical planning typically focuses on discrete, anatomically defined cortical regions. However, modern neuroscience demonstrates that most brain functions arise from distributed networks of interconnected areas rather than isolated spots …
Researching the Useful of Barb Suture in Obese Patients Undergoing Posterior Cervical Surgery
Through a single-center, exploratory clinical study, the safety and effectiveness of using barb wire in the incision and suture of posterior cervical surgery in obese patients were evaluated, providing a basis for its wide clinical application in posterior cervical surgery.
EASIX Score and Post-Induction Hypotension in Frail Patients Undergoing Non-Cardiac Surgery
Post-induction hypotension (PIH) is a common and clinically significant hemodynamic complication following general anesthesia induction. Frail patients are particularly vulnerable due to impaired vascular reactivity and endothelial dysfunction. The Endothelial Activation and Stress Index (EASIX), calculated from routine laboratory parameters (LDH, creatinine, and platelet count), may serve as a preoperative …
Specialist Nurse-Led Nursing Management for Patients Undergoing Head and Neck Cancer Surgery
The goal of this clinical trial is to evaluate the effectiveness of a multidisciplinary specialist nurse-led perioperative nursing management model for patients undergoing head and neck cancer surgery. The study aims to improve perioperative recovery, reduce postoperative complications, and enhance the quality of nursing care for patients with head and …
Nerve Transfer Surgery to Restore Upper-limb Function After Cervical Spinal Cord Injury
The goal of this prospective, open-label cohort study is to assess functional outcomes in individuals with cervical spinal cord injury who have undergone nerve transfer surgery to restore upper limb function. The main questions it aims to answer are: Does nerve transfer improve hand function in individuals with cervical spinal …
The Application of Infrared Thermography in the Prediction of Skin Healing in Surgery
This study investigates whether infrared thermography, a harmless and non-invasive thermal camera technique, can help monitor how surgical wounds heal after skin surgery. The goal is to detect wound problems earlier, such as infection or delayed healing, and to support doctors in making timely clinical decisions.
