What is perforated hollow viscus?
Viscus means organ. So hollow viscus means an organ than has a
lumen or open space within it, like the stomach and intestines.
Perforated hollow viscus is an organ with a lumen that has a hole
in it such that contents can escape from inside the organ to
outside the organ. If a gastric ulcer perforated, it would be a
perforated hollow viscus, allowing gastric acid and contents out
into the abdominal cavity.
