Filter by:Laparoscopic cholecystectomy has an increased incidence of extrahepatic biliary injury or bleeding. The common hepatic duct is on the medial border of the Calot triangle and at risk of injury. So, The investigators describe a new safety triangle with a more critical view of safety that is far from dangerous. Retrospectively, from December 2019 until March 2023, the investigators will review the medical records for patients who underwent laparoscopic cholecystectomy. The patients underwent cholecystectomy using a new technique in approaches to critical safety with recorded video and available follow up data were included. The patients who had intraoperatively extensive gallbladder adhesion that interfere with the dissection in this area, improper visualization of the cystic duct, patients whose did not operate by this new technique and patients whose have not video record of laparoscopic cholecystectomy will excluded from the study.
A single-blinded, prospective randomized parallel controlled clinical trial was designed and conducted from December 2019 to November 2020. 82 patients with a gallstone, gallbladder polyp and other benign gallbladder diseases were enrolled in this study. Finally, 82 patients were randomly divided into the Micro Hand S surgical robot group and the da Vinci surgical robot group. Standard robot-assisted transabdominal cholecystectomy was conducted using the Micro Hand S robot or the da Vinci robot. The success rate of operation, assembly time, operation time, intraoperative hemorrhage, time to first flatus, postoperative pain, comprehensive complication index, resident time and patient satisfaciton were recorded. The aim of the study is to determine whether the newly developed Chinese Micro Hand S surgical robot results in non-inferiority outcomes in cholecystectomy compared with the prevalent da Vinci robot.
In laparoscopic cholecystectomy method, Insufflation of CO2 in abdominal cavity causes positioning of the diaphragm upwards, a decrease in lung's volume and its compliance, an increase in the airway resistance, mismatch between the atelectasis and the ventilation perfusion. Although there are numerous studies in laparoscopic surgery, only a few of them investigate the effects of laparoscopic surgery on the cardiopulmonary and the respiratory mechanics. The investigator aimed To examine the effects of pressure-controlled and volume-controlled ventilation modes on cerebral oximetry and blood gases in laparoscopic cholecystectomy operations.
The importance of multimodal analgesia for postoperative pain management is well known and regional anesthesia techniques are commonly prefferred to provide better analgesia. Erector spinae plane block (ESB) is a new defined and effective regional anesthesia technique. But two injections can be unconfortable for some patients. With this study, we aimed to compare the analgesia effect of bilateral and unilateral ESP block for laparoscopic cholecystectomy.
