High-risk Patients With Acute Calculous Cholecystitis (ACC)
Conditions
Brief summary
Randomized controlled trial on high-risk patients with ACC. Consecutive patients with a diagnosis of ACC, if they meet the inclusion and exclusion criteria, will be randomized to receive Laparoscopic cholecystectomy (LC) or transmural ultrasound-guided gallbladder drainage (TUGD) with lumen-apposing self-expandable metal stents (LAMSs) within 10 days from onset of symptoms. Blood cultures will be performed at the time of admission, just before the procedure, 24 ± 3h after procedure, 72 ± 3h after procedure. Bile samples will be taken during the procedure for microbiological exam and culture. Blood samples will collected from all patients at the time of admission, just before the procedure, 24 ± 3h after procedure, 72 ± 3h after procedure. The follow-up will be performed after 30 days and after 6 months from intervention with an outpatient medical examination.
Interventions
TUGD will be performed using the bi-flanged LAMSs mounted on an electrocautery-enhanced delivery system (Hot-AXIOS™) by an experienced endoscopist defined as \> 10 LAMS positioning per year. The diameter and length of the stent and the modality of placing the stent (under complete EUS view or with endoscopic or fluoroscopic guidance) will be chosen at the discretion of the endoscopist performing the procedure
LC will be performed by the four-trocar technique with transection of the cystic duct and cystic artery after reaching the critical view of safety. ELC will be performed by a surgeon trained and experienced in laparoscopic surgery defined as \> 5 laparoscopic procedures for ACC on a yearly basis
