The position where the patient lies on the left side with the left leg slightly flexed is known as the Sims' position. This position is particularly useful for procedures or examinations involving the rectum as it allows for better access and visualization of the anal and rectal areas. By having the left leg flexed, it opens the pelvic region, facilitating the examination or intervention.

In contrast, the prone position would have the patient lying flat on their stomach, which is not suitable for rectal examinations. The lithotomy position involves the patient lying on their back with legs raised and supported in stirrups, primarily used for gynecological examinations. The dorsal recumbent position also has the patient lying on their back, with knees bent and feet flat on the table, making it less appropriate for rectal examination compared to the Sims' position.
