Q

Abdo pain DDX Peritoneum

A

1 or 2 peritonitis

primary spontaneous peritonitis = infection that develops in the peritoneum

secondary peritonitis, which usually develops when an injury or infection in the abdominal cavity allows infectious organisms into the peritoneum.

Q

Abdo pain DDx beware

A

• Always examine the hernial orifices.
• Always check for localised tenderness if colicky
abdominal pain becomes constant. Tachycardia,
fever and a raised white cell count suggests
infarction.
