Acute calculous cholecystitis, a condition marked by inflammation of the gallbladder due to gallstones, is typically treated through laparoscopic cholecystectomy, a surgical procedure to remove the gallbladder. Recently, a new approach called Endoscopic Ultrasound (EUS)-guided gallbladder drainage (EGBD) has emerged. This study aims to explore the effectiveness of EGBD in patients who are suitable for laparoscopic cholecystectomy. The researchers believe that EGBD could be a safe and practical alternative for these patients, potentially improving care and addressing current challenges in treatment. The study involves evaluating the feasibility of EGBD as a treatment for acute calculous cholecystitis. Participants will undergo EGBD, a procedure that drains the gallbladder using ultrasound guidance. The success of the treatment is measured by the complete resolution of symptoms associated with acute cholecystitis. This includes the disappearance of fever, relief from pain, and a decrease in white cell count by 10%. The study's primary focus is to determine if EGBD can effectively resolve these symptoms in patients who would typically undergo laparoscopic cholecystectomy.

30 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Criteria

Inclusion Criteria: Consecutive healthy patients aged ≥ 18 years old suffering from acute calculous cholecystitis indicated for laparoscopic cholecystectomy would be included. Exclusion Criteria: * Pregnancy * Patients unwilling to undergo follow-up assessments * Patients with suspected gangrene or perforation of the gallbladder * Patients diagnosed with concomitant liver abscess or pancreatitis (defined as elevated serum amylase more than three times the upper limit of normal) * Patients with duodenal obstruction * Altered anatomy of the upper gastrointestinal tract due to surgery of the esophagus, stomach and duodenum * Patients with liver cirrhosis, portal hypertension and/or gastric varices * Abnormal coagulation: international normalised ratio (INR) \> 1.5 and/or platelets \< 50.000/mm3 * Previous drainage of the gallbladder

Treatment Groups
Study Objectives

One single intervention group is designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
The procedure would be performed with a linear echoendoscope using a 10mm x 10mm or a 15 x 10mm stent. The distal flange of the stent would be deployed under EUS guidance, followed by deployment of the proximal flange under endoscopic guidance. Once deployed, the gallbladder would be completely emptied by suction and irrigation until the effluent through the stent is clean.
