Application of the Xi robotic platform for familial adenomatous polyposis with ultra-low rectal cancer: exploration of minimally invasive and refined therapies.

When a familial adenomatous polyposis (FAP) patient's rectal polyp undergoes malignant transformation, the surgeon needs to consider how to balance the quality of surgery with the patient's quality of life. Here, we present a case of robotic surgery in a patient with familial adenomatous polyposis and ultra-low rectal cancer. Fiberoptic colonoscopy found that hundreds of polyp-like bulges were diffusely distributed throughout the colon, and a malignant mass was found at the end of the rectum. The patient underwent total colectomy with abdominoperineal extended radical resection for rectal cancer using the Xi robotic platform. The patient recovered well in the postoperative period. The ileostomy was well used. And the patient was in good health and metastasis free at 9 months postoperatively. We identified total colectomy combined with extended radical rectal resection under the assistance of the da Vinci robot platform is of great benefit to the patient.
