In a procedure where the sigmoid colon is removed from the descending colon to the rectum, what is the correct PCS root operation?

• A. Resection
• B. Excision
• C. Removal
• D. Destruction

Answer: (A)

The main idea is determining which root operation fits removing a portion of a body part. When a segment of an organ is taken out, that action is described as a resection. In this scenario, the sigmoid colon is removed as a segment from the descending colon to the rectum, which is a partial removal of the colon. It’s not about removing a lesion within the organ (that would be excision), not about removing a device or foreign material (removal), and not about destroying tissue (destruction). Therefore, the appropriate root operation is resection.
