A safe sequential treatment approach for patients who have acute cholecystitis with severe inflammation: Transmural gallbladder drainage followed by laparoscopic cholecystectomy under the guidance of fluorescence imaging.

We reported a safe sequential treatment approach for the patient who required biliary drainage: EUS-GBD followed by laparoscopic cholecystectomy under the guidance of ICG fluorescence imaging. This sequential approach may improve patients' satisfaction with respect to quality of life during the waiting period and may ensure the safety of laparoscopic cholecystectomy.
