Final answer:
A circular stapler is commonly used during resection and reanastomosis of the distal colon or rectum to create a secure and integral bowel connection.
Step-by-step explanation:
A stapler commonly used during resection and reanastomosis of the distal colon or rectum is called a circular stapler. This type of surgical stapler is designed to create a circular anastomosis, which is essential during operations where segments of the colon or rectum are removed and the remaining ends need to be reconnected. The circular stapler ensures that the connection is secure and can maintain the integrity of the bowel lumen, which is crucial for patient recovery and function after the surgery.
