Second postoperative hemorrhage five weeks after transoral robotic surgery.

Transoral robotic surgery (TORS) is becoming widely used in Japan, and information on postoperative hemorrhage is needed. We treated a patient who developed a second massive postoperative hemorrhage on Day 35 post-TORS. The 69-year-old man was diagnosed with p16-positive, T1N1M0 stage I cancer of the anterior wall of the oropharynx.
