Filter by:The main purpose of this study is to investigate the region-specific cause of gallbladder stone incidence in Jeju Self-Governing Province, Korea.
The purpose of this study is to determine whether the magnetic compressive anastomosis has a better outcomes than traditional manual anastomosis on superior bilioenteric anastomosis.
Central South University in collaboration with Tianjin University developed the first domestically produced Chinese minimally invasive surgical (MIS) robot system which named "Micro Hand S" in 2013. Recently, as the domestic surgical robot research project's main section, this new MIS robot had been authorized to enter the clinical trial stage by the Ethics Committee of the Third Xiangya Hospital at Central South University.
This is a randomized double-blind placebo-controlled trial with a total of 100 patients who are free of gallstones at baseline. The study involves taking an oral drug (Ursodeoxycholic Acid 250mg) or a placebo twice daily for a period of six months and undergoing a total of three abdominal ultrasounds (at 6 months, at 12 months, and at 18 months) to check for gallstones.
The Study is designed to compare the effectiveness of Near Infrared Fluorescence Cholangiography (NIFC) to standard white light imaging (WLI) in visualizing and identifying the main biliary and hepatic structures (Cystic Duct, Right Hepatic Duct, Common Hepatic Duct, Common Bile Duct, Cystic-CBD junction, Cystic-Gallbladder junction and any Accessory Ducts) during laparoscopic cholecystectomy. The aim is to demonstrate that NIFC performs better than standard white light (WLI) alone in visualizing and identifying extra-hepatobiliary structures (Cystic Duct, Right Hepatic Duct, Common Hepatic Duct, Common Bile Duct, Cystic-CBD junction, Cystic-Gallbladder junction, and any Accessory Ducts) before and after dissection during Laparoscopic Cholecystectomy (LC).
Radiation exposure may put endoscopists at risk when performing endoscopic retrograde cholangiopancreatography. Although non-radiation endoscopic retrograde cholangiopancreatography was reported in pregnant women in previous reports, it remains unclear whether endoscopic retrograde cholangiopancreatography is also effective and safe when endoscopists were not expose to radiation. This study was to evaluate the effectiveness and safety of nonradiation-to-endoscopist endoscopic retrograde cholangiopancreatography in patients with complexity level I/II.
Cholecystectomy has been made with benign conditions usually. The aim of this study is to compare the macroscopic evaluations of the cholecystectomy specimens with it's histopathological examinations.
Randomized controlled trial to demonstrate the safety of early cholecystectomy (<72h) in patients with mild gallstone pancreatitis. The purpose of this study is to demonstrate that there is a shorter hospital stay and no higher complication rates.
Pneumoperitoneum is formed with CO2 during laparoscopic abdominal operations. Effect of pneumoperitoneum on coagulation factors is not well known. In our study the investigators aimed to compare the general anesthesia(GA) and combined spinal-epidural anesthesia (CA) during laparoscopic cholecystectomy(LC) with effect on coagulation factors. Fifty patients will be randomly assigned to either the Laparoscopic cholecystectomy under Combined anaesthesia (25 patients) or Laparoscopic cholecytectomy under general anaesthesia (25 patients). All patients has symptomatic gall stone disease or polyp of gall bladder.
Rationale: Several clinical feasibility studies have shown the potential benefit of near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG) for enhanced and earlier biliary anatomy visualization during laparoscopic cholecystectomy with the aim to reduce the number of vascular and biliary injuries. Although the incidence of injuries is low (0.7%), the impact on patients in terms of morbidity, quality of life and costs are dramatic. The Critical View of Safety (CVS) technique is regarded as the safety valve in conventional laparoscopic cholecystectomy (CLC). It is hypothesized that standard application of near-infrared fluorescence imaging during laparoscopic cholecystectomy can be useful to obtain establishment of CVS (at least 5 minutes) earlier and with more certainty regarding visualization when compared to conventional laparoscopic imaging alone. Study design: A multicenter randomized controlled trial with two study arms. Patients scheduled for an elective laparoscopic cholecystectomy will be recruited and randomized at the outpatient clinic (n = 308 total). One group will undergo near-infrared fluorescence cholangiography assisted laparoscopic cholecystectomy (NIRF-LC) and the other group will undergo conventional laparoscopic cholecystectomy (CLC). Compared with standard care, patients in the NIRF-LC group have to receive one preoperative intravenous injection of ICG. This is the only additional minimally invasive action for the patient. Initially, patients participating in this study will not benefit from the application of NIRFC during the surgical procedure. The administration of ICG and the modified laparoscope itself are not related with any kind of additional risk for the patient. Despite the encouraging results from several (pre)clinical feasibility studies, wide clinical acceptance of the routine use of ICG fluorescence laparoscopy is still lacking due to the absence of reliable and validated clinical data. A randomized clinical study is desirable to assess the potential added value of the NIRF imaging technique during laparoscopic cholecystectomy. Strong evidence in favor of routine implementation of this new imaging technique during laparoscopic cholecystectomy, will probably lead to worldwide routine application of the NIRF technique. Therewith long term sustainability of this research project is guaranteed.
