Study Comparing Limited and Extensive Neck Surgery in Oral Cancer Patients With Neck Spread
Oral cavity squamous cell carcinoma (OCSCC) frequently metastasizes to cervical lymph nodes, and the extent of neck dissection remains an area of ongoing debate in patients with clinically node-positive (cN1) disease. While modified neck dissection (MND, levels I-V) is widely practiced, selective neck dissection (SND, levels I-IV) may provide equivalent …
Pre-incisional Infiltration With Ropivacaine Plus Triamcinolone for Relieving Postoperative Pain After Thoracoscopic Surgery
Video-assisted thoracoscopic surgery (VATS) is less invasive compared to traditional thoracotomy, but it is still reported that the incidence of acute pain following VATS exceeds 80%. Inadequate postoperative analgesia may trigger a series of adverse physiological stress responses, increase the occurrence of postoperative complications, and affect the rehabilitation process. If …
Pre-incisional Infiltration With Ropivacaine Plus Triamcinolone for Relieving Postoperative Pain After Laparoscopic Surgery
Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. Studies have shown that up to 80% of patients experience postoperative …
Pre-incisional Infiltration With Ropivacaine Plus Diprospan for Relieving Postoperative Pain After Laparoscopic Surgery
Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery, but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. Studies have shown that up to 80% of patients experience postoperative …
Surgery Plus Postoperative Radiotherapy for T4 Sinonasal Adenoid Cystic Carcinoma: A Prospective Observational Study
This observational study follows patients with T4 stage sinonasal adenoid cystic carcinoma (a rare cancer of the nasal cavity/sinuses) who receive standard treatment: surgery followed by postoperative radiotherapy. The main goal is to measure the 3-year progression-free survival rate (the percentage of patients alive without cancer growth or spread). We …
Bilateral Erector Spinae Plane Block Versus Bilateral Oblique Subcostal Transversus Abdominis Plane Block for Postoperative Analgesia in Colorectal Surgery
This study aims to compare the ultrasound-guided bilateral erector spinae plane block (ESPB) and oblique subcostal transverse abdominal plane block (OSTAPB) for postoperative analgesia in colorectal surgery.
Management of Bone Loss in Orthopaedic Surgery Using the Masquelet Technique or Transport Nails
This is a single-center prospective observational study comparing two techniques for reconstructing bone loss in the lower limbs. The aim of the study was to compare the results of reconstructions using the Masquelet technique with reconstructions using electromagnetic transport nails. The primary endpoint was time to bone healing. This study …
The Necessity of Surgery in Patients With mGC Achieving Radiological Response After Conversion Therapy
The core of this study lies in directly addressing the most pressing clinical uncertainty in the current field: For patients with advanced metastatic gastric cancer who have achieved significant radiological remission after conversion therapy, should the addition of radical surgical intervention on top of the best medical treatment bring clear …
The Effect of Combined Iron Protocols on Perioperative Allogeneic Transfusion
The goal of this clinical trial is to learn if a combined iron supplementation regimen can reduce the need for blood transfusions in adults with iron-deficiency anemia undergoing major elective cardiac surgery. The trial will also look at whether this regimen is safe and well tolerated. The main questions it …
Intraperitoneal Infusion of Analgesic for Postoperative Pain Management
The study is a prospective, double-blinded, placebo-controlled multi-center trial to measure if postoperative pain and the amount of narcotics used are reduced by a clinically significant amount in women undergoing minimally invasive hysterectomy receiving a continuous infusion of intraperitoneal (IP) local anesthetic (LA) or a continuous infusion of LA combined …
