Active clinical trials for "Cholecystolithiasis"

The is a pilot study to evaluate the safety and efficacy of hybrid transvaginal-transabdominal procedures. Diagnostic peritoneoscopy (visualizing the inside of the abdomen), appendectomy (removal of the appendix), and cholecystectomy (removal of the gallbladder) will be performed through a vaginal incision with an additional small incision in the umbilicus.

The aim of the study is to investigate if P6 acupuncture made after induction of general anaesthesia might be effective for the prevention of PONV as ondansetron and if the acupuncture-ondansetron combination could enhance single therapy efficacy in patients undergoing laparoscopic cholecystectomy.

To discuss necessity of cholecystectomy for patients with stones in their bile ducts and gallbladders in the absence of absolute operation indications of cholecystectomy after clearance of bile duct stones with ERCP.

In this prospective study, the investigators assessed the utility of intermittent saline irrigation in reducing the recurrent rate of choledocholithiasis after the endoscopic extraction for common bile duct stones, and it does not increase the rate of procedure-related complications.

This pilot study aims to determine the utility of direct Magnetic Resonance Cholangiopancreatography (MRCP) in the assessment of suspected acute gallstone disease presentations. This will take the form of a randomized controlled trial, the design of which is based on recent internal audit data which indicated that a high proportion of patients ultimately require MRCP prior to diagnosis, treatment and discharge, and suggested that early scan may improve overall costs and outcomes. Patients with symptoms and signs suggestive of suspected gallstone disease and deranged liver function tests/amylase (i.e. suggestive of a potentially obstructive gallstone disease), will be enrolled across the full range of 'front-door' locations for surgical presentations within the hospital (Emergency Department, Surgical Emergency Unit, Ambulatory Assessment Unit), and randomized to one of two diagnostic pathways which are both existing variations in current clinical care: MRCP is used as the first mode of imaging; following a standard care model (ultrasound then MRCP if deemed appropriate). An assessment will then be undertaken of the cost-effectiveness of early MRCP versus standard care, using the primary outcome measure of cost to diagnostic scan report calculated using hospital episode statistics (HES), with secondary outcome measures to assess the overall utility which include length of stay, time to diagnosis, overall cost of admission using HES, in-hospital complications, Patient Reported Outcome Measures (PROMs), readmission and re-attendance rates (ED/GP), and service/radiology costs.

A disposable endoscopy system (NCKU-scope-01) was developed for the evaluation of bile duct stone or neoplasm. This system consists of a camera, light sources, a working channel, and a water injection channel. The endoscope could be inserted into the common bile duct via the working channel of a commercial duodenoscope. This study aims to test the feasibility and safety of this system. The efficacy of stone and neoplasm diagnosis will also be analyzed.

Lignocaine is a local anaesthetic that is widely used in all medical and surgical fields. Many clinical studies have shown that intravenous (IV) lignocaine given in the perioperative period was safe, reduced airway complications, obtunds cough reflex, reduce sore throat, pain, opioid consumption, nausea, length of hospital stay. Multiple animal studies have shown that IV lignocaine was able to lower anaesthetic gas requirements. Desflurane is an anaesthetic gas that has a rapid onset and offset of action. This study aims to evaluate the effect of IV lignocaine infusion on desflurane requirements. Hypothesis of the study is that IV lignocaine infusion reduces desflurane requirements.

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).

The burden of iatrogenic bile duct injury (BDI), the most feared complication of laparoscopic cholecystectomy (LC), is extremely high and the repercussions on the patient's outcomes may be severe ranging from intraoperative repair to liver transplant or patient's death. Different techniques have been proposed to prevent BDI. Our hypothesis is that a fluorescence-based Imaging would allow visualization of the biliary tree anatomy as good as with the Intraoperative Cholangiogram with several main advantages: ease of use lack of invasiveness absence of ionizing radiation to the patient and the operating staff performed prior to any dissection (prior to "critical view of safety") Capacity of enhanced-reality based on virtual cholangiography (computer treatment of MRI images) to guide biliary tree anatomy visualization will be also evaluated in this study. The study requires a 2-month patient participation.

Surgical removal of the gallbladder is needed in 1 million people per year in the USA. The procedure is done by placing four tubes (cannula) from 5 to 10 mm through the abdominal wall. Air is placed in the abdominal cavity and a lighted scope is placed through one cannula. The space in the abdominal cavity can then be seen on a video screen. Thin retractors and dissecting instruments are placed through the other cannula and the gallbladder is removed using the video screen for vision. The gallbladder duct and the artery are usually occluded with clips or stitches. In this study we propose to do the procedure though a single 5 mm incision placed at the umbilicus and a second access through the vagina using a flexible endoscope. The gallbladder will be retracted using strings (sutures) attached to the gallbladder. The dissection will be done using laparoscopic instruments (scissors, knives, dissectors) placed through the laparoscopic port. A flexible grasper may be used in the endoscope to help with retraction. An endoscopic snare or grasper will be used to grasp the gallbladder and remove it from the abdomen through the vagina. This study evaluates the ability to do laparoscopic cholecystectomy with one skin incision and one vaginal incision. This will provide the basis for future studies evaluating decreased pain and costs with transvaginal assisted cholecystectomy.
