Filter by: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.
The aim of this current study is to investigate the effectiveness and safety of a novel technique which is the 5-5-5-8 where the camera port is 5 mm.
The goal of this clinical trial is to test intracranial blood flow and cerebral oxygenisation changes in patients who have pneumoperitoneum in laparoscopic cholecystectomy procedure. The main questions aim to answer are: - How does pneumoperitoneum in laparoscopic cholecystectomy procedure changes blod flow in patients? - Are there any differences between Near-Red spectroscopy and transcranial doppler ultrasonography assesment? Participants will be diagnosed with using NIRS probes and Doppler ultrasonography probes if any changes in surgical procedure. Researchers will compare NIRS and TCD detection outcomes to see if there is any differences.
The aim of this study is to evaluate the effect of TENS (Transcutaneous Electrical Nerve Stimulation) on patient outcomes after laparoscopic cholecystectomy.
Laparoscopic cholecystectomy has an increased incidence of extrahepatic biliary injury or bleeding. The common hepatic duct is on the medial border of the Calot triangle and at risk of injury. So, The investigators describe a new safety triangle with a more critical view of safety that is far from dangerous. Retrospectively, from December 2019 until March 2023, the investigators will review the medical records for patients who underwent laparoscopic cholecystectomy. The patients underwent cholecystectomy using a new technique in approaches to critical safety with recorded video and available follow up data were included. The patients who had intraoperatively extensive gallbladder adhesion that interfere with the dissection in this area, improper visualization of the cystic duct, patients whose did not operate by this new technique and patients whose have not video record of laparoscopic cholecystectomy will excluded from the study.
Laparoscopic cholecystectomy (LC) gained popularity among general surgeons in 1990s and rapidly become one of the most commonly performed procedures in digestive surgery, with more than one million cholecystectomies being performed in the United States per year. LC remains also one of the most commonly performed procedure by general surgeons during the training period. Even if previous report LC cases performed by surgical trainees (ST) are not associated with higher operative morbidity, the length of operative time is significantly increased when compared with that of LC cases performed by attending surgeons, due, most of all, to difficulties in identifying the anatomical structure, and this sometimes leads to an attending surgeon taking away the case from the trainee. Furthermore, despite the fact that LC has proven to be a safe procedure, the rate of common bile duct (BDI) injury still remains unacceptably high even in the hands of minimally invasive trained surgeons ranging from 0.2 to 1.5% in individual reports, much higher than initial reports, associated with significant morbidity and mortality, lower quality of life and increased costs, related to additional health care measures, loss of work days, and insurance claims. The aim of this study is to address which of the techniques now available could be addressed as the best option in a training setting to enhance the learning curve, to ideally build a safe cholecystectomy training program and virtually eliminate the risk of BDI due to anatomic misinterpretation during the training period.
A single-blinded, prospective randomized parallel controlled clinical trial was designed and conducted from December 2019 to November 2020. 82 patients with a gallstone, gallbladder polyp and other benign gallbladder diseases were enrolled in this study. Finally, 82 patients were randomly divided into the Micro Hand S surgical robot group and the da Vinci surgical robot group. Standard robot-assisted transabdominal cholecystectomy was conducted using the Micro Hand S robot or the da Vinci robot. The success rate of operation, assembly time, operation time, intraoperative hemorrhage, time to first flatus, postoperative pain, comprehensive complication index, resident time and patient satisfaciton were recorded. The aim of the study is to determine whether the newly developed Chinese Micro Hand S surgical robot results in non-inferiority outcomes in cholecystectomy compared with the prevalent da Vinci robot.
In Denmark, more than 7500 cholecystectomies are performed every year. Common bile duct gallstones (CBDS) are found in 3.4% to 18% of patients undergoing cholecystectomy. A two-step approach including endoscopic retrograde cholangiography (ERC) with stone extraction and papillotomy with subsequent laparoscopic cholecystectomy has become gold standard for treatment of CBDS in Denmark. However, ERC is associated with a high risk of complications and more than 50% of patients require multiple ERCs. Recent meta analyses find that a one-step approach might be superior in terms of safety, CBDS clearance rate, hospital stay, operative time, hospital cost and stone recurrence, but much more data is needed. The preGallstep trial is an investigator-initiated multicentre randomised clinical pilot trial with blinded outcome assessment investigating a novel one-step laparoscopic cholecystectomy with common bile duct exploration and stone extraction versus conventional two-step endoscopic retrograde cholangiography with stone extraction plus a subsequent laparoscopic cholecystectomy for patients with CBDS. After enrolment, the participant will be randomised to one of the two treatment approaches. Adult patients with imaging confirmed CBDS are eligible for inclusion. Potential postoperative complications will be assessed within 90 days following the procedure. The primary outcome is the proportion of serious adverse events (corresponding to a Clavien-Dindo score II or above) requiring re-intervention within 90 days of the initial procedure. This outcome will be used for a future sample size calculation. The sample size estimate, the inclusion rate and the estimated length of subsequent trial will be used to determine the feasibility of a large pragmatic and confirmatory trial. We hypothesize that the one-step approach will significantly reduce the risk of complications and number of treatments needed thereby making a difference to hundreds of people in Denmark each year.
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.
In laparoscopic cholecystectomy method, Insufflation of CO2 in abdominal cavity causes positioning of the diaphragm upwards, a decrease in lung's volume and its compliance, an increase in the airway resistance, mismatch between the atelectasis and the ventilation perfusion. Although there are numerous studies in laparoscopic surgery, only a few of them investigate the effects of laparoscopic surgery on the cardiopulmonary and the respiratory mechanics. The investigator aimed To examine the effects of pressure-controlled and volume-controlled ventilation modes on cerebral oximetry and blood gases in laparoscopic cholecystectomy operations.
