Caecal perforation in large-bowel obstruction.

Reports of two unusual cases of obstructive caecal perforation are presented, and the relevant literature is reviewed. It is suggested that the prime factor in obstructive caecal perforation is ischtemia. The importance of recognizing and treating impending perforation of the caecum in large-bowel obstruction is emphasised. Caecostomy is recommended for small perforations, but resection is indicated if more extensive ischcemia is present.
