Pancreaticobiliary Reflux in Patients Without Cholelithiasis

Pancreaticobiliary Reflux

Pancreaticobiliary reflux has been found in patients with cholelithiasis and gallbladder cancer associated with normal pancreaticobiliary union. However, the presence of pancreaticobiliary reflux has not been studied in patients without gallstones (healthy gallbladders). The authors believe that pancreaticobiliary reflux might be a normal phenomenon in patients with and without gallstones, although in patients with cholelithiasis it might constitute a pathological condition associated with dismotility of the biliary tree and the sphincter of Oddi.

Comparing Epidural Versus General Anesthesia for LESS Cholecystectomies

Cholelithiasis

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.

Randomized Trial Comparing Gastric Bypass With and Without Cholecystectomy

Roux-en-Y Gastric BypassCholecystitis; Gallstone1 more

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.

Impact of Video Editing Training for Novice Trainees in Laparoscopic Cholecystectomy

Gallstone; Colic

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.

Multibending vs Conventional Endoscope for Direct Peroral Cholangioscopy

Common Bile Duct CalculiBiliary Tract Cancer2 more

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.

Rate of Duodenal-biliary Reflux Increases in Patients With Recurrent Common Bile Duct Stones

Common Bile Duct Gall StonesCommon Bile Duct GallStones

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.
