Active clinical trials for "Cholecystitis"

Acute lithiasis cholecystitis (ALC) is the third most common cause of surgical emergency admission. The initial treatment of ALC associates a medical support and a cholecystectomy, preferentially performed laparoscopically in the first 5 days of evolution. During the surgery, intraoperative cholangiography (CPO) using a contrast product is the "gold standard" to identify the bile ducts. However CPO is performed in approximately 30% of laparoscopic cholecystectomy. Laparoscopic cholecystectomy for ALC is associated with an increase in the rate of biliary ducts injuries compared with cholecystectomy for symptomatic vesicular lithiasis, evaluated at 0.8 % versus 0.1 %. Its higher rate is related to local inflammation that alters the biliary anatomy and complicates the identification of the bile ducts. Indocyanine green facilitates the visualization of extrahepatic biliary structures, which could reduce the risk of biliary wound and shorten the operating time.

Laparoscopic cholecystectomy is one of the most common gastrointestinal surgeries. However, it can be technically complex in those patients diagnosed with acute cholecystitis who present severe inflammation or fibrosis, with bile duct injury being one of its main complications. The use of fluorescence cholangiography through the use of indocyanine green allows the identification of extrahepatic biliary structures, facilitating dissection and reducing the risk of bile duct lesions. Better visualization of the bile duct allows reducing the conversion rate to open surgery, as well as operating time. The main objective is to assess a decrease in operating time in acute cholecystitis undergoing emergency surgery, to which indocyanine green is administered preoperatively. Randomized, prospective, controlled, multicenter clinical trial of two groups of patients diagnosed with acute cholecystitis and requiring urgent cholecystectomy. The control group includes 220 patients who undergo urgent laparoscopic cholecystectomy according to the usual technique without the administration of indocyanine green, and the intervention group includes 220 patients who undergo urgent laparoscopic cholecystectomy for acute cholecystitis with the administration of indocyanine green preoperatively. Study led by the Parc Taulí University Hospital in Sabadell.

More than 10% of Canadians have gallstones, and approximately 10% of these individuals will develop gallbladder inflammation related to gallstones, which is referred to as acute cholecystitis (AC). Patients with AC who do not have their gallbladder surgically removed have a 30% risk of serious complications that can lead to death. Surgery is the only definitive treatment for AC, however, there is controversy regarding the ideal timing of surgery. The two main approaches are early surgery (typically within 7 days of diagnosis) or delayed surgery (7 days to 6 weeks after diagnosis). Although preliminary evidence suggests that early surgery is associated with shorter hospital length of stay, lower risk for complications, and lower costs, practice varies widely regarding the timing of surgery. The limitations of the existing studies include small sample sizes, varied definitions of early versus delayed surgery, and an imbalance of risk between study groups. The proposed pilot study aims to inform the design of a large clinical trial that will compare the outcomes of patients with AC who receive accelerated surgery (i.e., as soon as possible with a goal of surgery within 6 hours of diagnosis) with those who receive standard care.

To evaluate the feasibility of performing EGBD as a treatment of acute calculous cholecystitis in patients that are indicated for laparoscopic cholecystectomy.

This study compares the visualizationrate of fluorescent and X-ray cholangiography during laparoscopic cholecystectomy for acute cholecystitis

laparoscopic cholecystectomy nowadays is the most common surgery done by General surgery surgeons , so it is necessary to evaluate the difficulty of each case prior to surgery and from the first look ,to avoid complications and improve outcomes , so scoring systems are needed for better assessment of the overall condition and make good decision .

ActivSightTM combines an innovative form factor and proprietary software to deliver precise, objective, real-time visualization of blood flow and tissue perfusion intraoperatively for laparoscope-based surgery. A small adaptor that fits between any existing laparoscope and camera systems and a separate light source placed along any current commercial system will deliver objective real-time tissue perfusion and blood flow information intraoperatively. Primary Objective: To determine safety and feasibility of ActivSightTM in displaying tissue perfusion in intestinal anastomoses including colorectal and bariatric surgery. Secondary Objective: To determine the efficacy of ActivSightTM in; (1) displaying tissue vascularity and perfusion in comparison to indocyanine green (ICG) during gastrointestinal anastomoses; and (2) displaying biliary tree during laparoscopic cholecystectomy using ICG-based intraoperative cholangiography (IOC).

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.

Acute cholecystitis (AC) is defined as an acute inflammatory disease of the gallbladder consequently to the presence of sludge or stones. AC accounts for 3-10% of all cases of abdominal pain. Cholecystolithiasis accounts for 90-95% of all causes of acute cholecystitis, while acalculous cholecystitis accounts for the remaining 5-10% of the cases. Laparoscopic cholecystectomy is actually the gold standard treatment for acute cholecystitis (AC) although it is always not suitable for patients who are poor candidates for surgery [ ]. In 2001 Giovannini et al. described the first EUS-guided biliary drainage (EUS-BD) through a transduodenal access with a needle knife. Subsequently, EUS-BD has considerably evolved thanks to the development of dedicated devices such as lumen apposing metal stents (LAMS), specifically designed for endoscopic ultrasound procedures. LAMS are made up of braided nitinol, that is fully covered with silicone to prevent tissue ingrowth, with wide flanges on both ends to provide anchorage. Recently, LAMS have been incorporated into a delivery system with an electrocautery mounted on the tip which allows the device to be used directly to penetrate the target structure without the need to utilize a 19G needle, a guidewire, and a cystotome for prior dilation. Different are actually the indication of the LAMS for different disease and its use has been described for drainage of peri-pancreatic fluid collections, common bile duct (CBD), gallbladder, and for creation of gastro-jejuno anastomosis. Recently, endoscopic gallbladder (GB) drainage was found to be a potentially revolutionary alternative for cholecystectomy for the control of symptoms, definitive treatment, or bridging therapy until surgery is possible. Before the advent of LAMS, the standard of care of acute cholecystitis (AC) was the percutaneous drainage (PTC) and after the advent of these new stents, different series showed the higher technical and clinical success of the EUS-gallbladder drainage (EUS-GB) for acute cholecystitis, with a lower recurrence rate, than PTC. The superiority of this technique was assessed in terms of technical and clinical success, AEs and AC recurrence if compared to the endoscopic drainage. This could be explained with the use of larger caliber stents, allowing an effective drainage, with low risk of stent occlusion. Finally, a recent study with a long-term follow-up showed as the outcomes of EUS-GBD for AC were comparable with LC with acceptable rates of recurrent acute cholecystitis.

This clinical trial is an exploratory clinical trial that evaluates the necessity and effectiveness of empirical antibiotic use in mild and moderate acute inflammatory gallbladder diseases that require surgery, and the incidence of postoperative infection-related complications is compared.
