简要总结
Most patients with rectal cancer receive neoadjuvant therapy. This usually causes a decrease in tumor size. In approximately 20% of patients who receive neoadjuvant therapy, the tumor disappears completely (complete pathological response), showing as a scar on the rectal mucosa, not noticeable from the rectal serosa, from outside the rectum, difficulting the identification of the tumor location by the surgeon.
Rectoscope (p201630551) allows the surgeon to view the illuminated rectum from the patient's abdomen, determining the appropriate point of section of the rectum.
