CPT® Code 45111

The CPT® Code 45111 refers to a surgical procedure known as a proctectomy, specifically a partial resection of the rectum performed via a transabdominal approach. This procedure is typically indicated for patients requiring surgical intervention on the proximal aspect of the rectum, often due to conditions such as malignancies, severe trauma, or other significant rectal diseases. The transabdominal approach involves accessing the rectum through a midline incision in the lower abdomen, allowing the surgeon to explore the abdominal cavity and identify the appropriate site for resection. The procedure entails mobilizing the sigmoid colon and rectum, followed by the careful division of the rectum to remove the affected segment. The remaining segments of the rectum are then reconnected through an anastomosis, ensuring continuity of the gastrointestinal tract. This surgical intervention is critical for restoring function and alleviating symptoms associated with rectal pathologies.
