Postoperative Adhesion after Thyroid Surgery

Purpose: Postoperative adhesion after thyroidectomy results in neck discomfort and swallowing difficulty. However, risk factors for adhesive symptom after thyroidectomy have not been well studied. This study evaluated symptoms related to postoperative adhesion after thyroidectomy. Methods: The Glasgow-Edinburgh Throat Scale (GETS) questionnaire was used to evaluate postoperative adhesion. Patients who completed the GETS questionnaire either pre- or post- operatively were enrolled. Patient clinical and pathological details including age, gender, body weight, body mass index (BMI), tumor size, thyroid volume, extent of thyroidectomy, postoperative months, and neck thickness on ultrasonography and computed tomography (CT) were abstracted. Results: Twenty-eight preoperative (22 females, six males) and 101 postoperative (83 females, 18 males) patients were enrolled. The mean age of the pre-operative enrollees was 52.1±11.7, and of post-operative enrollees 51.8±12.4 years. Patients who were within one month post-surgery had higher GETS scores than preoperative patients (27.4±20.1 vs. 6.5±11.1, P＜0.001). Two months after surgery, GETS scores of postoperative patients did not differ significantly from the scores of the preoperative patients. There were no significant associations between clinical and pathologic features (age, tumor size, BMI, neck thickness on ultrasonography and CT) and GETS scores. Conclusion: Postoperative adhesive symptoms were most severe at one month after surgery, while questionnaire scores two months after surgery were comparable with preoperative patients. Further studies will be required for better understanding of the natural course of postoperative adhesion after thyroidectomy.
