The rectum is part of the distal part of the gastrointestinal tract; it is between the sigmoid colon and anus.
Definition
Abdominoperineal resection specimen showing the rectum.
Pathologist generally agree that: the rectum starts/sigmoid ends @ place where serosa ends on the posterior aspect of the bowel.
Note:
- There are several definitions for the rectum.[1]
- In a survey of surgeons:[2]
- 67% defined it by an anatomical landmark
- 35% of all respondants considered the peritoneal reflection the proximal boundary of the rectum.
- 30% defined the proximal boundary as a distance from the anal verge.
