Filter by: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.
The incidence of Gall Stones after Bariatric surgery and its association with weight loss
Choledocholithiasis is identified in approximately 3-10 % of patients with cholelithiasis. (1-3) While laparoscopic cholecystectomy (LC) is considered the treatment of choice in patients with gall bladder stones, there is a debate about the management of common bile duct (CBD) stones, (4) and this has led to a range of therapeutic strategies for the management of concomitant gallstones and CBD stones patients. Two-stage endoscopic management using endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy is a common approach, although single-stage management by laparoscopic cholecystectomy with surgical exploration of the CBD is an alternative, with the single-stage approach more common in the open surgery era. Currently, it is unclear whether two-stage management is better than or at least equivalent to the single-stage surgical approach to choledocholithiasis. To address this, we undertook this study to compare these two approaches. The aim of this prospective randomized trial was to determine the best technique for the management of patients with concomitant gallstones and common bile duct stones, by comparing the success rate, complication rates, and longer-term follow-up outcomes.
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.
Acute pancreatitis (AP) is an inflammatory disease of the pancreas, most commonly caused by gallstones, or excessive use of alcohol. It represents a management challenge and a significant healthcare burden. The incidence of AP ranges globally from 5 to 30 cases per 100.000 inhabitants/year, and there is evidence that the incidence has been rising in recent years. The overall case-fatality rate for AP is roughly 5%, and it is expectedly higher for more severe stages of the disease. In most cases (80%), the outcome of AP is rapidly favorable. However, acute necrotizing pancreatitis (ANP) may develop in up to 20% of cases, and is associated with significant rates of early organ failure (38%), needing some type of surgical/endoscopic intervention (38%) and death (15%). In the United States, AP is a leading cause of inpatient care among gastrointestinal conditions: more than 270.000 patients are hospitalized for AP annually, at an aggregate cost of over 2.5 billion dollars per year. In Europe, the UK incidence of AP is estimated as 15-42 cases per 100.000/year and is rising by 2.7% each year. Despite existing evidence-based practice guidelines for the management of biliary AP, clinical compliance with recommendations is poor, with studies on this field identifying major discrepancies between evidence-based recommendations and daily clinical practice. Audits about biliary AP have been performed in Italy, Germany, France, and England, with quite disappointing results. Indeed, in these audits, the treatment of biliary AP differed substantially from the recommendations. For example, less than 15% of the responders stated that they strictly followed all recommendations included in the guidelines in Germany and 25.8% of patients did not receive definitive treatment for biliary AP within 1 year in the UK. These findings support the view that publication alone of nationally or internationally developed and approved guidelines is insufficient to modify the practice of non-specialists and raises the question of how best to spread guideline recommendations. In 2020, the spread of the virus Covid-19 has represented a pandemic that also had a profound impact on the surgical community. There are many ways through which the outbreak of the Covid-19 pandemic could have influenced daily clinical practice for patients with biliary AP also leading to a failure to adhere to the recommendations coming from the guidelines, especially those regarding the early and definitive treatment with cholecystectomy or ERCP and sphincterotomy. First of all, the recommendation to postpone all non-urgent endoscopic procedures during the peak of the pandemic. Second, the recommendation to conservatively treat inflammatory conditions such as acute cholecystitis and acute appendicitis wherever possible. Since the clinical compliance with recommendations about AP is poor and the impact of implementing guideline recommendations in biliary AP has not been well studied on a global basis, we launched the MANCTRA-1 study with the aim to demonstrate areas where there is currently a sub-optimal implementation of contemporary guidelines on biliary AP. Moreover, we argue that during the Covid-19 pandemic the tendency to disregard the guidelines recommendations has been more marked than usual and we will try to find out if AP patients' care during the Covid-19 pandemic resulted in a higher rate of adverse outcomes compared to non-pandemic times due to the lack in the compliance of the guidelines. The MANCTRA-1 can identify a number of areas for quality improvement that will require new implementation strategies. Our aim is to summarize the main areas of sub-optimal care to provide the basis for introducing a number of bundles in the management of AP patients to be implemented during the next years. The primary objective of the study is to evaluate which items of the current AP guidelines if disregarded, correlate with negative clinical outcomes according to the different clinical presentations of the disease. Secondary objectives are to assess the compliance of surgeons worldwide to the most up-to-date international guidelines on biliary AP, to evaluate the medical and surgical practice in the management of biliary AP during the non-pandemic (2019) and pandemic Covid-19 periods (2020), and to investigate outcomes of patients with biliary AP treatment during the two study periods.
To investigate feasibility and safety of intraoperative bile duct clearance by sphincter of Oddi balloon dilatation via cystic duct at cholecystectomy. Primary endpoint: rate of successful bile duct stone clearance (feasibility). Secondary endpoints (safety): rate of peri-interventional complications (injury to the common bile duct, bleeding, injury to surrounding organs: stomach, duodenum, liver) and short-term postoperative complications (bile leak, cholangitis, lipasaemia, pancreatitis, pneumonia). Duration of procedure. Length of hospital stay.
Retrospective study to analyze benign complications and malignancy risks after ERCP with sphincterotomy. All patients who received a ERCP with sphincterotomy for a benign disease will be included. Post-ERCP hepato-biliary complications in the follow-up will be registered.
The investigators want to study the effectiveness of prophylactic cholecystectomy in patients with midgut neuroendocrine tumor (jejunum, ileum or proximal colon) who require primary tumor surgery. When patients are diagnosed and are tributary to surgical treatment, the tumor might compromise vascularization, and patients need an extensive bowel resection. The patients might also receive medical treatment with somatostatin analogs. The combination of extensive bowel resection and medical treatment might increase gallbladder stones, but patients might not develop biliary stone disease, as in the general population, where 20% of the population have gallbladder stones but only a 10 to 15 % of the population will develop symptoms. The idea comes from the lack of literature about the incidence of biliary Stone disease in patients with midgut NET tumors. It's a multicentric, open-label and randomized clinical trial to evaluate the incidence of biliary stone disease in patients with midgut NET who require primary tumor surgery combined or not to cholecystectomy. Our hypothesis suggests that patients with midgut neuroendocrine tumor who require primary tumor resection without the combination of prophylactic cholecystectomy do not have an increased incidence of biliary stone disease two years after the surgery, regardless of treatment with SSA.
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.
The aim of the study is to evaluate the difference of postoperative analgesic effects and opioid consumption between ultrasound-guided unilateral oblique subcostal, posterior, or dual TAP blocks in patients undergoing laparoscopic cholecystectomy for cholelithiasis.
