They have the same shape as these.

Doughnuts, also donuts, in pathology refer to the ring-shaped piece of large bowel from a circular end-to-end stapling device.[1]

These are also known an EEA donuts and CEEA donuts.[1] CEEA is circular end-to-end anastomosis. EEA is trademarked. Presumably, it is an abbreviation for end-to-end anastomosis.

CEEA staplers are particularly useful in low lying tumours; they allow more individuals to safely have a lower anterior resection instead of the less desirable abdominoperineal resection (APR).[2]

Pathology in donuts

The value of assessing donuts in the context of lower anterior resections is questioned. A study of 125 individuals by Speake and Abercrombie found the pathologic assessment of donuts added nothing significant.[3] A larger study of 336 individuals by Ng et al. reached the same conclusion and noted that the cost of processing all those donuts by pathology costed over $60,000 (US dollars).[4]
