Active clinical trials for "Gallstones"

While gold standard in the treatment of symptomatic gall stones is laparoscopic cholecystectomy with instruments introduced through multiple abdominal wall incisions, transvaginal access to the peritoneal cavity offers an alternative avoiding injury of the abdominal wall. Transvaginal hybrid-NOTES cholecystectomy has been demonstrated effective and safe. However it has not been demonstrated up-to-date if intraoperative cholangiography is feasible during such procedure. This observational case series describes success and technical feasibility of intraoperative cholangiography during transvaginal cholecystectomy. The investigators hypothesis is that cholangiography is feasible equal to conventional laparoscopic cholecystectomy.

The purpose of the study is to determine if adding Benadryl improves sedation for patients scheduled to undergo ERCP or EUS procedures.

This study is a prospective, comparative, controlled, blinded study that will enroll a total of 70 adults that will undergo elective laparoendoscopic single-site incision gallbladder removal. The objective of this study is to compare Epidural versus General Anesthesia for postoperative pain, length of hospital stay, outcomes, and cost of post-cholecystectomy patients.

The main objective of this pilot study is to show feasibility to collect peri-operative and postoperative clinical data of the study group of gastric bypass without cholecystectomy compared with the control group of gastric bypass with cholecystectomy. Our hypothesis is that the approach without cholecystectomy would be superior in terms of a decrease of perioperative adverse events and postoperative complications, as well as lenght of operation, lenght of hospital stay, overall costs with a very low risk of biliary complication in the follow up. These findings could be helpful to build a baseline for a future randomized controlled multicenter study allowing significance of these results and help orientate surgeons towards best surgical care of the gallbladder with confirmed absence of stones in the obese patient undergoing gastric bypass.

Surgical practice training often suffers from poor educational efficiency due to the technical difficulties of the cases, the lack of resources and the cases in the operating room. The video editing training method is not included in the standard surgical training, but it has the advantage of reducing trial and error and errors during surgery, simplifying training time, and cost-effective. Investigators analyzed whether the video editing teaching method has effective value for trainees compared to the traditional teaching method. The primary purpose of the study is the trainee's learning achievement in terms of surgical skills. Learning achievement is measured as the difference in pre- and post-educational test scores (The Global Operative Assessment of Laparoscopic Skills (GOALS)) to compare the difference in achievement. The secondary objective of the study was to evaluate the satisfaction with the video editing method as an educational method by conducting a questionnaire survey to all the trainees participating in the study. In addition, the degree of postoperative pain, postoperative hospitalization period, postoperative readmission and the need for additional procedures were compared and analyzed.

The aim of this study is to evaluate the usefulness of a newly developed multibending ultra-slim upper endoscope for the successful direct peroral cholangioscopy (POC) without assisting accessory in comparison with conventional ultra-slim endoscope. The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.

Virtual reality devices are widely accepted tools to familiarize surgical novices with the principles of laparoscopy. Free Virtual reality training will be tested against basic training and efficacy assessed in a randomized controlled trial of surgical novices.

The aim of this study is to improve the technique of laparoscopic cholecystectomy by using a flexible endoscope passed through a single umbilical skin incision, as previously reported, now with the use of Manually Articulating Devices (Ethicon Endo-Surgery, Inc.) through the endoscope.

This study proposes evaluation of an educational tool, a laparoscopic virtual reality simulator. The purpose of this study is to determine whether training on the LapSim Simulator transfers to improved laparoscopic cholecystectomy operative performance in an animal model.

ERCP is the primary choice for removal of common bile duct stone (CBDS) currently. However, 4-24% patients underwent recurrence after successful clearance of CBDS. Stone re-formation due to chronic inflammation of biliary duct is generally considered an important cause of CBDS recurrence, which is associated with duodenal-biliary reflux (DBR) after sphincterotomy. Although it was believed that DBR was the important cause of CBDS recurrence, the direct evidence was still lacking. Here we conducted a case control study to investigate the DBR rate in patients with recurrent CBDS after ERCP.
