Pearls
• CT is the most sensitive modality to detect complications of endoscopy.
• Rectosigmoid junction is the most frequent site of perforation.
• Most cases are managed conservatively.

is used to detect cancers in the large intestine.
• Rarely, this may produce a hole in the intestinal wall resulting in air and other contents to leak out into the belly.
• This is an emergency…
