BACKGROUND
Transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) has been associated with improved long-term dysphagia symptomatology compared with chemoradiation. Dysphagia in the perioperative period has been inadequately characterized. The objective of this study was to characterize short-term swallowing outcomes after TORS for OPSCC.
METHODS
Patients undergoing TORS for OPSCC were enrolled prospectively. The Eating Assessment Tool 10 (EAT-10) was used as a measure of swallowing dysfunction (score >2) and was administered on postoperative day (POD) 1, 7, and 30. Patient demographics, weight, pain level, and clinical outcomes were recorded prospectively and focused on time to oral diet, feeding tube placement, and dysphagia-related readmissions.
RESULTS
A total of 51 patients were included with pathologic T stages of T1 (n = 24), T2 (n = 20), T3 (n = 3), and Tx (n = 4). Self-reported preoperative dysphagia was unusual (13.7%). The mean EAT-10 score on POD 1 was lower than on POD 7 (21.5 vs 26.6; P = .005) but decreased by POD 30 (26.1 to 12.2; P < .001). Forty-seven (92.1%) patients were discharged on an oral diet, but 57.4% required compensatory strategies or modification of liquid consistency. Ninety-eight percent of patients were taking an oral diet by POD 30. There were no dysphagia-related readmissions.
CONCLUSION
This prospective study shows that most patients who undergo TORS experience dysphagia for at least the first month postoperatively, but nearly all can be started on an oral diet. The dysphagia-associated complication profile is acceptable after TORS with a minority of patients requiring temporary feeding tube placement. Aggressive evaluation and management of postoperative dysphagia in TORS patients may help prevent dysphagia-associated readmissions. Cancer 2017. © 2017 American Cancer Society.
