A member asked:
Can you provide an exhaustive list of all possible causes of crescent-shaped thin stool (excl. rectal cancer b/c i just had lar a month ago)?

Short list: Assuming your anastomosis is fine and not stenotic the most common cause is your muscles around your anal canal (schinter muscles and puburectalis) are not relaxing appropriately during defecation (animus). The best test for this is a voiding proctogram but would wait 6 to 8 weeks from your surgery (lar) to have this done.

Stricture: A stricture would be a common reason after an lar. Another could be spasm of the sphincter muscle. Not drinking enough water could also contribute.

Needs evaluation.: A careful rectal exam by an expert might provide the answer.
