Active clinical trials for "Cholecystitis"

Objectives Acute cholecystitis commonly occurs in elderly patients who are at high-risk for surgery. Whether upfront Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is advantageous over antibiotics first for mild acute cholecystitis is uncertain. Hypothesis to be tested The aim is to compare EUS-GBD versus standard protocol (antibiotics first) as a definitive treatment, in very high-risk patients suffering from mild to moderate acute cholecystitis. We hypothesize that EUS-GBD can reduce the 1-year risk of recurrent acute cholecystitis. Design and subjects This is an international randomised controlled study including consecutive patients suffering from acute cholecystitis that are very high-risk for cholecystectomy. The patients would be randomized to receive EUS-GBD or antibiotics first. Interventions: EUS-GBD versus antibiotics Main outcome measures: The primary outcome is the rate of recurrent acute cholecystitis in 1 year. Other outcomes include technical and clinical success, post-procedural pain scores, analgesic requirements, adverse events, re-admissions, re-interventions, quality of life and cost analysis. Data analysis All outcomes would be analysed according to the intention-to-treat principle. Kaplan-Meier method with the log-rank test will be used to compare differences in recurrent acute cholecystitis in 1 year. A health economic analysis will also be performed. Assuming a 17.1% difference in recurrent acute cholecystitis rates, a 2-sided P value of 0.05, a power of 80%, and a 10% dropout rate, 110 patients is required. Expected results The findings of this study can help establish the role of EUS-GBD in management of high-risk patients suffering from acute cholecystitis over antibiotics alone and Percutaneous transhepatic gallbladder drainage.

Gallstone is a common disease in China.At present, the prevalence of gallstones in China is 15 %, and about 210 million people are sick. Acute cholecystitis is acute gallbladder inflammation, is one of the main complications of cholelithiasis or gallstones. The removal of gallbladder and gallstones in patients with acute cholecystitis in the presence of biliary pain will prevent the recurrence of gallbladder and reduce the risk of cholecystitis progression. If gallbladder perforation is not treated in time, the mortality rate is 30 %. Acute acalculous cholecystitis without treatment will be life-threatening, with a mortality rate of up to 50 %. At present, the vast majority of patients with acute cholecystitis are treated with 4-hole traditional laparoscopic cholecystectomy and open cholecystectomy. Their postoperative quality of life, pain and scar-related complications, remain major factors for patients.In recent years, with the renewal of the concept of minimally invasive surgery and the continuous advancement of instruments and technology, single-incision laparoscopic cholecystectomy has also maximized the quality of life after surgery and reduced postoperative pain and scar-related complications. At present, there are few reports on randomized controlled clinical trials of SILC in patients with acute cholecystitis, and there is a lack of large sample size studies.Due to the difficulty of SILC operation, the longer learning curve, the different equipment conditions and technical characteristics of each center, and the lack of standardized training, there is no effective consensus on the application indications and operation procedures of SILC in acute cholecystitis surgery. Based on the current status, the purpose of this study was to investigate the effect of SILC on postoperative quality of life, postoperative pain, scar assessment and postoperative complications in patients with acute cholecystitis, so as to propose a standardized single incision laparoscopic operation procedure in the treatment of acute cholecystitis.

The present study aims at analyzing whether ultrasonic tissue coagulation dissection technique offers a smoother peri- and postoperative course and reduces the risk for conversion from laparoscopic to open surgery in acute cholecystectomy patients as compared to electrocautery in case of acute cholecystitis The study is performed as a double-blinded study on patients undergoing laparoscopic surgery for acute cholecystitis. Patients included in the study are randomized to surgery with either the traditional electrocautery based technique or ultrasonic scalpel based dissection.

The aim of this study is to evaluate the effect of TENS (Transcutaneous Electrical Nerve Stimulation) on patient outcomes after laparoscopic cholecystectomy.

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.

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.

A Phase 2, Multi-Center, Randomized, Placebo-Controlled, Dose-Finding Study Evaluating Efficacy, Safety and Tolerability of Different Doses and Regimens of Allocetra-OTS for the Treatment of Organ Failure in Adult Sepsis Patients

In this project the investigators propose to carry out a clinical trial that compares non-endoscopic treatment of cholecystitis with antibiotics versus endoscopic drainage in non-operable acute cholecystitism (AC), especially focused on the rate of subsequent EBP and recurrence of AC, as well as the impact on the quality of life, also exploring the costs. The ultimate goal of this project is to generate knowledge and scientific evidence that makes it easier for health professionals to choose the most appropriate strategy for non-operable patients with lithiasic AC. Ourworking hypothesis is that endoscopic treatment (EUS-GBD) will significantly reduce the number of EBP compared to non-endoscopic treatment in patients with non-operable lithiasic AC.

Laparoscopic cholecystectomy (LC) represents the gold standard for treatment of elective and acute of gallbladder diseases, such as acute cholecystitis (AC). However, in elderly patients or in those with severe comorbidities, urgent LC can be associated with increase morbidity (up to 41%) and mortality (up to 19%). In these patients, placement of a percutaneous gallbladder drainage catheter (PT-GBD) or colecistostomy can be utilized to drain the gallbladder until infection is resolved, as a bridge to subsequent surgery or as definitive treatment. PT-GBD, however, is associated with major adverse events (AEs): intra-hepatic hemorrhage, pneumothorax, biliary peritonitis, bile leak from the site of drainage, AC recurrency, self-removal of the drainage by the patient e/o for spontaneous migration. Recently, to overcome PT-GBD limitations, EUS-guided gallbladder drainage (EUS-GBD) has been introduced as an alternative minimally invasive therapeutic intervention for treatment of patients with high surgical risk who present with AC. The procedure has high technical and clinical success rates and favorable safety profile, with low risk of recurrent AC. EUS-GBD, followed, when needed, by intra-cholecystic endoscopic interventions has been utilized even in relatively young patients as recently reported with successful intra-cholecystic giant stones clearance through the LAMS using previously described endoscopic lithotripsy in patients who rejected surgery and desired gallbladder preservation. A second category of patients who might benefit from EEGBT are elderly individuals with major comorbidities posing them at high surgical risk, who suffer from previous episodes of cholecystitis, recurrent colic episodes due to gallbladder stones, or with biliary acute pancreatitis due to stones migration. Based on all the above considerations, we have designed a prospective, pilot study to evaluate the safety and efficacy of elective EEGBT performed using LAMS stent with electrocautery-enhanced delivery system, followed by intra-cholecystic endoscopic interventions when needed in elderly patients with benign gallbladder diseases at high surgical risk, in whom an indication to perform cholecystectomy was indicated.

The purpose is to find out if intraoperative acupuncture performed by needling PC 6 and LI4 point bilaterally, and Yin Tang point will help reduce the incidence postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when added to a prophylactic regimen consisting of ondansetron and dexamethasone. The hypothesis is that the addition of this acupuncture treatment to ondansetron and dexamethasone given for prophylaxis will help reduce the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when compared to patients receiving ondansetron and dexamethasone without acupuncture.
