Rectal stricture formation is a rare complication of aortic aneurysm repair
. Two case are described here. A combination of hypotension, a compromised
internal iliac circulation and poor collateral supply following inferior me
senteric artery ligation can result in acute ischaemic proctitis - an infre
quently described clinical entity. Ulceration and necrosis are the sequelae
of prolonged ischaemia and fibrous stricture formation may result. One pat
ient responded to dilatation and posterior mid-rectal myotomy; the other fa
iled to respond to conservative measures and eventually had an end colostom
y fashioned following intractable symptoms.
