Summary

This study tested a procedure called EUS-guided gallbladder drainage (EGBD) as an alternative to gallbladder removal surgery for 30 adults with acute cholecystitis (gallbladder inflammation). The goal was to see if it could safely resolve symptoms like fever and pain without needing an operation. The approach uses a thin tube with a camera to place a stent, draining the gallbladder through the stomach or intestine.
