Active clinical trials for "Gallstones"

Short-term studies have shown that patients with short bowel syndrome (SBS) often develop cholestasis or cholelithiasis. In this retrospective cohort study, we aimed to define the incidence, risk factors, and clinical consequences of cholelithiasis in adults with SBS over an extended time period.

It is a cross sectional study in which we are tying to determine frequency of type of gall stones in our setup(Lahore, Pakistan).

Background. X-ray cholangiography has a high sensitivity and specificity of detecting bile duct stones and is the gold standard. There are no studies describing the sensitivity and specificity of IFC for bile duct stone detection. Research question. What is the sensitivity of IFC to visualize bile duct stones? Method. Prospective study with 40 patients undergoing planned laparoscopic cholecystectomy with preoperative magnetic resonance cholangiopancreatography (MRCP) (gold standard) and intraoperative IFC, X-ray cholangiography and choledochuscopy in that order. Primary outcome. Sensitivity of visualization of bile duct stone by fluorescent cholangiography and secondary outcome is visualization of anatomy.

Comparing the use of surgical robotics during a Cholecystectomy, comparing different platforms and approaches (multi port verses single port).

Aims: To prospectively investigate the accuracy of surgeon-performed ultrasound for the detection of gallstones. Methods: 179 adult patients, with an acute or elective referral for an abdominal ultrasound examination, were examined with a right upper quadrant ultrasound scan by a radiologist as well as surgeon. The surgeons had undergone a four-week long education in ultrasound before participating in the study. Ultrasound findings of the surgeon were compared to those of the radiologist, using radiologist-performed ultrasound as reference standard.

Compliance to the clinical pathway, postoperative complication and total cost of the hospitalisation of patients undergoing elective cholecystectomy for symptomatic cholecystolithiasis were collected over two different periods: using a clinical pathway in form of a paper based check-list (group 1, n=118) or a clinical pathway integrated into the paper based medical treatment and nursing documentation (group 2, n=123). Outcome measures were compliance of the clinical pathway and total costs per case.

Background Laparoscopic cholecystectomy is a very common procedure. Postoperative pain, especially around the umbilical port is dominating the first postoperative week. Single Incision Laparoscopic cholecystectomy (SILC) has been proposed to diminish postoperative incisional pain and improve cosmetic results, but results are not convincing and the risk of formation of an umbilical trocar-site hernia is not properly investigated. This study aimed to investigate the risk of umbilical trocar-site hernia formation after SILC vs. conventional 4-port laparoscopic cholesystectomy. Methods This is a cohort registry study with prospective questionnaire and clinical follow-up on 239 patients having a SILC from 1/1 2009 to 1/6 2011 vs. 478 mathed patients having a conventional laparoscopic cholecystectomy (consecutively from one month before and after SILC. They are matched for age, gender, date of operation, and surgeons skills (database from intraoperatively registered data). Primary endpoint is umbilical trocar-site hernia formation (operation for a umbilical hernia or clinical hernia). The H0 hypothesis is that there is not difference between SILC and conventional. Exclusion criteria are: death, operation for acute cholecystitis. The included patients will be sent a questionnaire asking for operation for a hernia in the area, suspicion of a hernia, and perioperative data that we do not have in the database. Futhermore those patients who suspect a hernia will be invited to aclinical exam by a medic to state the diagnosis. Furthermore we patients are asked to report if they have chronic pain and/or discomfort.

The aims of this study were to investigate what measures were taken when common bile duct stones (CBDS) were found intraoperatively in Sweden during the period May 2005 to December 2009 by using data from this population-based nationwide registry, and analyze the outcome in terms of complications and success rates of bile duct clearance in relation to various stone sizes and interventions used. In order to further characterize the natural course of CBDS of various sizes, particular interest was focused on patients with positive findings where no peroperative measures to clear the bile ducts were taken or planned postoperatively.

The objective of this study is to prospectively compare laparoscopic ultrasound to transabdominal ultrasound for the detection of gallbladder pathology in obese patients presenting for laparoscopic gastric bypass. We hypothesize that laparoscopic ultrasound will be more sensitive and specific for cholelithiasis than transabdominal ultrasound in morbidly obese patients.

This study aims to determine the repeatability and reproducibility of Quantitative Magnetic Resonance Cholangiopancreatography (MRCP). Imaging scientists at Perspectum Diagnostics have developed a hessian-based mathematical model to enhance conventional MRCP to a 3D geometric model of the biliary tree, 'Quantitative MRCP'. This enables advanced quantitative measurement of bile duct width, orientation, branching point and curvative metrics. The technology has been validated against 3D printed phantoms for accuracy, and early clinical research has demonstrated the technology has potential for clinical impact, with improvement in radiologist performance versus conventional non-enhanced MRCP imaging (Vikal et al 2017). Quantitative MRCP aims to act as a tool to not only improve assessment of the current status of the biliary tree, but also act as a mechanism to track change within the ducts. Thus, it must be established that any change between scans is due to change in the physiology of the individual and not due to a quirk or fault of the technology. In order to achieve this a series of scans will be performed on an individual over a short period of time, for which the condition of the biliary tree within that individual can be assumed to be constant. Between each scan, subject and coil repositioning will occur. The study will recruit a group of adult volunteers, from both diseased groups and healthy groups in order to achieve a range of physiological biliary metrics.
