Endosonography-guided Gallbladder Drainage vs Non-endoscopic Treatment in Inoperable Acute Cholecystitis

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.
