Distension can lead to decreased blood flow to the gallbladder, causing tissue death and eventually gangrene. Once tissue has died, the gallbladder is at greatly increased risk of rupture (perforation). Rupture can also occur in cases of
Out-of-body experience study to identify brain regions affected by this stimulation.
