Limited endoscopic sphincterotomy with balloon dilation（ESBD）is a promising technique in treating common bile duct stones. It had the similar success rate of stone extraction, but its incidence of complications remained uncertain. However, there is no clinical evidence and guideline to define the optimal duration of balloon dilation so far. So we designed a prospective randomized trial to compare the effect of three different duration of balloon dilation during ESBD so that we can find the optimal duration of the balloon dilation.
This study evaluates life quality of patients who were diagnosed with gallbladder benign disease through Gastrointestinal Quality of Life Index (GIQLI) scale. Researchers will establish a database including 20,000 patients. Through observational followup and statistic analysis，identifing a model or scale to standardized surgical indication, help surgeons and patients determine the best treatment decision.
Aimed to evaluate laparoscopic cholecystectomy by retro-infundibular (RI) approach compared to standard laparoscopic cholecystectomy (SLC) in difficult cases with scarred chole-cystohepatic (Calot's) triangle.
This study evaluates the clinical application of cholangiojejunostomy in the surgical treatment of cholelithiasis with Moderate dilatation of common bile duct. Half of participants will receive hepatectomy, cholangiojejunostomy and T-tube Drainage, while the other half will receive hepatectomy and T-tube Drainage.
Endoscopic bile duct stone (BDS) removal is a well-established treatment; however, the preference for basket or balloon catheters for extraction is operator-dependent It is reported that complete endoscopic treatment with a single catheter is more likely when choosing a balloon catheter over a basket catheter for extraction of BDSs≤10mm. However, a study comparing the two catheter types in patients with periampullary diverticulum has not been performed, and there is no strong basis on which to recommend the balloon catheter as a first-line stone removal device. The investigators therefore conducted a multicenter prospective randomized trial to compare catheter performance in patients with periampullary diverticulum.
110 patients with common bile duct (CBD) stones and had one or more anther preoperative predictors for high risk for difficult cholecystectomy admitted to departement of surgery of Minia university hospital for ERCP then laparoscopic cholecystectomy (LC). the patient divided into 2 equal group. in group 1, nasobiliary (NB) catheter was inserted during ERCP after CBD clearance. In group 2, only CBD clearance was done. In all patients LC was done within the same week of ERCP. Tans-nasobiliary Intraoperative cholangiography was done and methylene blue injected at the end of the procedure to detected any leak in NB group
Introduction: Three-dimensional key-hole surgery ('laparoscopic') systems are proven to reduce the time required to complete tasks in laboratory settings. This benefit derives from the addition of binocular depth perception cues when compared to two-dimensional (2D) systems. This year a '4K' laparoscopic system has become commercially available, so-named as it provides a high resolution 2D image with four times the number of pixels of 2D full high definition. The improved visualisation is likely to provide additional non-binocular depth cues. It is currently unclear to what degree improving the resolution of 2D systems can compensate for binocular depth cues. Aim: To determine whether the binocular vision provided by 3D laparoscopic systems provides benefits during laparoscopic cholecystectomy when compared to the monocular vision provided by high-resolution 4K systems. Methods: A randomised controlled trial of 3D HD versus 4K laparoscopic systems will be performed, comparing the time to complete laparoscopic cholecystectomy, and error scores. Impact: This study is a unique, first-of-its-kind investigation into two new surgical technologies, and is the first study to involve a 4K system. The uptake of three-dimensional systems has been curbed by financial cost and the limitations of early 3D technologies. This study aims to determine which system may be the safest, quickest and most cost- effective, in order to guide future investment and technological development towards either 3D or 2D systems. In addition, these systems may also aid in the learning curve of trainee surgeons.
Summary 1. Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. 2. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.
Collection of PROMs (Patient Reported Outcome Measures) data from patients before and after an operation to remove their gallbladder for the treatment of symptomatic gallstones. This PROMs data will provide information to clinicians and trusts about the health gain following this type of surgery and the impact on patient's quality of life. This information will be collected by the implementation of the patient Website aboutmyop.org. This will not only allow patients to complete quality of life (PROMs) questionnaires online, but will also allow them to access information on their condition and necessary surgery, in addition to post-operative follow-up.
