Final answer:
The low-lithotomy position is commonly used during an Abdominoperineal resection, which is a surgery for colorectal cancer requiring access to the lower gastrointestinal tract.
Step-by-step explanation:
The surgical procedure in which a low-lithotomy position is commonly used is D. Abdominoperineal resection. This position involves the patient lying on their back with hips and knees flexed, thighs apart, and feet supported in stirrups, allowing surgeons to access both the abdominal and perineal regions. The low-lithotomy position is typically employed when procedures require access to the lower gastrointestinal tract, particularly the rectum and anus, as is the case with an abdominoperineal resection. This resection is a surgery performed to treat colorectal cancer and involves the removal of the distal colon, rectum, and anus.
