Surgeon experience and complications with Transoral Robotic Surgery (TORS).

Abstract

To investigate surgeon preferences for perioperative management of transoral robotic surgery (TORS) and explore the frequency of postoperative complications. Retrospective survey. Multi-institutional. An electronic survey was sent to over 300 TORS-trained surgeons in the United States identified by Intuitive Surgical, Inc. Participation was voluntary and solicited by email invitations to participate 3 times over a 1-month period. A total of 2015 procedures were reported by 45 respondent TORS-trained surgeons: 67% academic, 33% nonacademic. A minority of TORS procedures (n = 214, 10.6%) were performed on previously irradiated patients. Neck dissections were performed concurrently (58%) or staged (42%). Fewer than 6% of TORS procedures required tracheotomy or reconstruction. Most surgeons (62%) initiated oral intake on postoperative day 0-1. Of the patients who required readmission, bleeding (n = 62, 3.1%) was the most common cause followed by dehydration (n = 26, 1.3%). Other complications of surgery included tooth injury (n = 29, 1.4%), percutaneous endoscopic gastrostomy (PEG) dependency >6 months (n = 21, 1.0%), temporary hypoglossal nerve injury (n = 18, 0.9%), and lingual nerve injury (n = 11, 0.6%). A total of 6 deaths (0.3%) were reported within 30 days of TORS. All reported deaths were due to postoperative hemorrhage. The complication rate decreased significantly with higher surgeon case volume (>50 cases). TORS is associated with a low major complication rate, early initiation of oral intake, and a low rate of long-term PEG dependency. Postoperative hemorrhage was the most common cause of hospital readmission and postoperative mortality.
