Filter by:This is a longitudinal observational study on patients with gastrointestinal and related disease. The study will be conducted for at least 10 years, following each participant over time, as they either go through relapses and remissions, or progression of their disease.
This study evaluates operative and non-operative management of acute appendicitis (infection or inflammation of the appendix) and acute cholecystitis (inflammation/infection of the gallbladder) in patients with active mild to moderate COVID-19 infection. The hypothesis is that COVID+ patients with uncomplicated acute appendicitis or acute cholecystitis amendable to a laparoscopic procedure can have safe operative outcomes compared to those managed non-operatively.
The Institute of Imaged-Guided Surgery (IHU Strasbourg) has two clinical Magnetic Resonance Imaging (MRI) scanners, one with a 3T (3 Teslas) magnetic field used for diagnosis, the other with a magnetic field of 1,5T (1,5 Teslas) used for the interventional (Pre / per / postoperative). The reference for the visualization of the biliary and pancreatic ducts is a relatively long sequence that needs a breathing-synchronized acquisition leading to artefacts on the images (blur effect). In order to reduce and/or standardize the acquisition time as well as to limit artefacts, accelerated sequences are developed. Such sequence is available in France recently in the form of WIP Siemens (Work In Progress: sequence in test phase at manufacturer to be marketed in the short or medium term on clinical machines). It incorporates a Compressed Sensing (CS) acquisition scheme allowing the acquisition of a 3D (3 dimensions) sequence similar to the usual sequence by drastically reducing the acquisition time, the sequence CS-SPACE. This sequence exists in two forms: - An ultra-rapid sequence acquired in apnea - An accelerated sequence but remaining synchronized with the breath. The study carried out here on a large number of patients, with two different magnetic fields, applied routinely for diagnosis or anticipation of surgery, could be used by the community of radiologists, hepatogastroenterologists and also digestive surgeons Hepatobiliary.
The study is designed to assess the awareness of the SAGES Safe Cholecystectomy Program among polish surgeons, as well as the degree of implementation of this Program during laparoscopic cholecystectomy performed in Poland. It also gathers the opinion of polish surgeons on usefulness of each of the SAGES Safe Cholecystectomy Rules
Randomized controlled trial to demonstrate the safety of early cholecystectomy (<72h) in patients with mild gallstone pancreatitis. The purpose of this study is to demonstrate that there is a shorter hospital stay and no higher complication rates.
It is well established that hemolytic diseases predispose patients to the development of pigment gallstones. Gallstones are noted in at least 5% of children under the age of 10 years, increasing to 40-50% in the second to fifth decades. The co-inheritance of Gilbert's syndrome increases the risk of cholelithiasis four to five-fold. In patients with chronic hemolysis, total bile lipid concentration is decreased and the total bilirubin to total lipid ratio is increased. This suggests that the conjugating capacity of hepatocytes is surpassed by the excessive amount of bilirubin resulting from hemolysis. Increased bilirubin monoconjugate and unconjugated bilirubin can precipitate in bile and form complexes with inorganic ions, mostly calcium, and develop into stones. Patients with hemolytic disorders can also develop biliary sludge, a suspension of precipitated particulate matter in bile dispersed in a viscous, mucin-rich liquid phase . The chemical composition of the precipitates correlates well with the composition of the associated stone and sludge often stands as a harbinger of future stone development. There is strong data suggesting a benefit in treating cholelithiasis with UDCA and also in preventing gallstone development in various high risk scenarios. There are several proposed mechanisms for the positive effect of UDCA in primary prevention of pigment stones. Mucoglycoproteins are present in significant amounts in black pigment stones and contribute to the matrix of gallstones. UDCA suppresses the secretion of protein and decreases the levels of various proteins in bile . It has also been suggested that increased colonic bile salt may solubilize unconjugated bilirubin and may prevent calcium complexing. There is no published data at present on the role of UDCA in prevention and treatment of cholelithiasis in hemolytic diseases. The investigators hypothesise that UDCA can be of benefit to patients with hemolytic disorders in the primary prevention of pigment stones, possible resolution of biliary sludge and existent stones, and reduction of symptomatic episodes of cholelithiasis.
This is a one center, Phase IIa, randomized, double blind, placebo controlled study designed to evaluate the efficacy and safety of two Aramchol doses in subjects 18 to 75 years of age, with newly formed cholesterol gallstones in their gallbladder following bariatric surgery confirmed by gallbladder ultrasound ..
The primary purpose of this study is to compare the effect of lidocaine and dexamethasone on postoperative quality of recovery after laparoscopic cholecystectomy
The trial aims to assess the value of two-regimen antibiotic prophylaxis versus placebo in elective laparoscopic cholecystectomy.
The purpose is to study natural process of gallstones in common bile duct, stones less than or equal to 6 mm. And if the gallstones give any complications under 1 year follow up. The second outcome is to study side-effects of gallstones removed with surgery.
