Abnormal swelling or enlargement of the gallbladder due to fluid accumulation or obstruction.
From Greek 'chole' (bile) + 'kystis' (bladder) + 'ektasis' (stretching or dilation). The '-ectasia' suffix describes pathological expansion of hollow organs, established in medical terminology by the 1800s.
When doctors see a balloon-like gallbladder filling with bile on ultrasound, they use this term—it's one of those medical words that literally describes what they're seeing: something stretched dangerously wide.
