Background: Cholecystitis is treated by in various types of hospitals by different specialists, and treatment strategy is influenced by logistical and medical reasons and personal preference. This may significantly impact hospital stay and other outcomes. Purpose: To determine the variation in treatment of cholecystitis in the Netherlands and its impact on outcome. Methods: Nation-wide cohort study of all patients diagnosed and treated for cholecystitis during a 6 month period. The primary outcome will be the proportion of patients with an acute cholecystitis in which the guideline is followed. This group will be compared to those in which the guideline is not followed, focussing on total hospital stay and complications. Secondary aims are to determine: factors related to guideline compliance; the best method of cystic duct closure; the best treatment strategy for a >7-day existing cholecystitis; factors predictive for concomitant common bile duct stones; strategies following gallbladder drainage. Multivariable analysis and propensity score matching will be used when appropriate for the etiological study aims. The TRIPOD guideline for prediction modelling will be used for the predictive study aims. Hospitals will receive their own results, set out against the national average and best practices, thereafter subsequent changes in hospital practice will be recorded. Conclusion: This study will determine the variation in treatment of cholecystitis in the Netherlands and its impact on clinical outcome. Its results will serve as an important incentive to create optimal, uniform cholecystitis treatment in the Netherlands.
Migration of stones from the gallbladder to the common bile duct (CBD) facilitated by gallbladder contractions can be listed as a complication of gallstones disease. In the case of common bile duct stone (CBDs) migration, an endoscopic cholangiopancreatography (ERCP) should be offered for both symptomatic and asymptomatic patients fit for the procedure. An ERCP with an adequate endoscopic sphincterotomy obtains a complete biliary clearance in about 80-90% of the patients[5]. Whilst most cases are successfully treated with such first-line approaches, about 10-15% need alternative and/or adjunctive techniques to achieve bile duct clearance. These conditions are generally defined as "difficult" bile duct stones, a broad category of cases that encompasses very different scenarios. In the case of irretrievable CBDs, the European Society of Gastrointestinal Endoscopy (ESGE) recommends the endoscopic placement of a temporary biliary plastic stent to warrant biliary drainage. Since their introduction, fully covered self-expanding metal stents (FCSEMS) have rapidly been adopted for the treatment of benign biliary conditions such as strictures, leaks, or bleeding. In a recent retrospective study it has been shown that FCSEMS are useful in the approach of difficult lithiasis of CBD with no significant adverse events associated. Moreover, a promising FC-SEMS with a particular prosthesis design (flare type - Niti-S "S-Type" Taewoong) could be even more useful since it reduces the frequent complication of fully covered stents which is the migration of the prosthesis. However, prospective data on the effectiveness and on the adverse events rate on the use of SEMS for incomplete stone CBDs clearance are still lacking. Therefore, the investigators aim to estimate the incidence of adverse events, complete biliary clearance, and migration rate after 3-6 month from ERCP index (stent positioning), comparing plastic stents vs FC-SEMS (Niti-S "flare type" - Taewoong).
The MINERVA (Machine learnINg for the rElapse Risk eValuation in Acute biliary pancreatitis) project stems from the need in the clinical practice of taking an operational decision in patients that are admitted to the hospital with a diagnosis of acute biliary pancreatitis. In particular, the MINERVA prospective cohort study aims to develop a predictive score that allows to assess the risk of hospital readmission for patients diagnosed with mild biliary acute pancreatitis using Machine Learning and artificial intelligence. The objectives of the MINERVA study are to: 1. Propose a novel methodology for the assessment of the risk of relapse in patients with mild biliary acute pancreatitis who did not undergo early cholecystectomy (within 3 to 7 days from hospital admission); 2. Propose a Machine Learning predictive model using a Deep Learning architecture applied to easily collectable data; 3. Validate the MINERVA score on an extensive, multicentric, prospective cohort; 4. Allow national and international clinicians, medical staff, researchers and the general audience to freely and easily access the MINERVA score computation and use it in their daily clinical practice. The MINERVA score model will be developed on a retrospective cohort of patients (MANCTRA-1, already registered in ClinicalTrials.gov) and will be validated on a novel prospective multicentric cohort. After validation, the MINERVA score will be free and easy to compute instantly for all medical staff; it will be accessible at any time on the MINERVA website and web app, and will provide an immediate and reliable result that can be a clear indication for the best treatment pathway for the clinician and for the patient.
The goal of this clinical trial is to compare outcomes for interval or early laparoscopic cholecystectomy in patients with moderately severe and severe pancreatitis. The main question[s] it aims to answer are: - To establish whether there is a difference in surgical outcomes comparing patients diagnosed with severe or moderately severe pancreatitis on which early cholecystectomy was performed versus performing interval cholecystectomy. - The primary endpoint will be to evaluate major complications, defined as a Clavien-Dindo score greater than or equal to III/V. - Secondary endpoints include evaluating minor complications (defined as a Clavien-Dindo score below III/V), biliary disease recurrence, mortality, postoperative hospital stay and postoperative admittance into an intensive care unit. Participants will be randomly assigned to either group: early cholecystectomy during the pancreatitis hospitalization or interval cholecystectomy scheduled 4 weeks after clinical resolution of pancreatitis.
The goal of this clinical trial is to learn about Application and translational research of 3D printed models in the surgical treatment of common bile duct stones under endoscopic retrograde cholangiopancreatography. The main question it aims to answer are:Compare the differences in stone removal time, surgical complications, and surgical success rate during ERCP (+EST) surgery between 30 patients who used 3D printing preoperative simulation and 30 patients who did not use it. Participating patients will be divided into two groups, one group of 30 patients will use 3D printed models for preoperative simulation planning and then undergo surgery, and the other group will undergo surgery directly without using 3D printed models.
The modified laparoscopic transcystic biliary drainage which we developed in the treatment of cholecystocholedocholithiasis has some advantages over conventional techniques. Here, a 7-Fr triple-lumen 30-cm central venous catheter was adopted to replace conventional 5-Fr ureteral catheter, which extended the function of the C-tube. Then we developed a continued suture and circling manner by the V-Loc closure device, which simultaneously covered and anchored the C-tube. Theoretically, this modified laparoscopic transcystic drainage not only provide safe and effective bile duct drainage, but also provide a convenient access of treatment for postoperatively retained bile duct stones, which may expand the indication of initially laparoscopic operation in the management of cholecysto-choledocholithiasis.
Upper abdominal pain (UAP) is a common symptom and frequently the reason to visit the hospital. The prevalence of epigastric pain in the Dutch population is estimated to be as high as 37%. Moreover, Dutch hospitals yearly record >100.000 diagnoses related to UAP. In most patients, UAP can be attributed to symptomatic (functional) dyspepsia (FD), Irritable Bowel Syndrome (IBS) or uncomplicated gallstone disease (cholecystolithiasis), with a prevalence in the general population of 20-30%, 20%, and 6-9%, respectively. However, these conditions may have overlapping symptom patterns and generally affect similar populations. which contributes to ineffective (diagnostic) interventions. Patients are generally not aware of the similarity of symptoms and the poor outcome of some treatments. Education positively influences patients' self-management and health judgment. In a recent open-label, multicentre trial the effectiveness of web-based patients' education is applied to reduce overuse of upper gastrointestinal endoscopies in patients with dyspepsia. This study illustrated that an web-based education tool safely reduced 40% in upper gastrointestinal endoscopies. Lifestyle interventions (such as change of diet and/or physical activity) are widely incorporated in treatment programs for cardio-vascular diseases including diabetes mellitus and obesity. An web-based education tool on upper abdominal pain and other complaints combined with a lifestyle interventions for patients may be an effective treatment option for this large group of patients. This study investigates the potential of an individualized web-based education tool as intervention for patients with functional dyspepsia, irritable bowel syndrome and uncomplicated symptomatic cholecystolithiasis with the possibility to visit the Prevention and Lifestyle clinic (RELIEF pathway). The RELIEF pathway aims to reduce unnecessary health care utilization and, secondly, to maintain and improve quality of life by educating patients on lifestyle improvement.
The aim of the study is to establishing a standardized biobank and a clinical information database for patients with benign and malignant tumors of the biliary system. With follow-up plans and advanced multiomics technology, a multiomics database for patients with benign and malignant tumors of the biliary tract will be further established. Based on the above work, real-world clinical research on the diagnosis and treatment of biliary tract tumors is about to be carried out, and a high-standard cohort research foundation is laid for precision therapy based on multiomics characteristics and molecular typing of biliary tract tumors.
The goal of this work is to assess the best time to perform LC combined with LCBD exploration and the feasibility and safety of such procedure in patients with combined GBS and CBDS after failure of ERCP extraction of CBD stones .
