anastomotic doughnuts


A term of art for an annular piece of the GI tract which is taken distal to the margin of resection, usually for cancer, and analysed separately. Proximal doughnuts may be taken during re-anastomosis.

Published colorectal cancer data suggest no role for the histological analysis of the anastomotic doughnuts following anterior resection of the rectum. In contrast, doughnut involvement with cancer provides useful prognostic information post-oesophagogastrectomy and thus histological examination of upper gastrointestinal doughnuts is justified. Doughnut involvement might justify the use of adjuvant therapy. 

Synonyms Anastomotic donut, donut, doughnut
