Endoscopic versus Conventional Thyroid Surgery: A Comparison of Quality of Life, Cosmetic Outcomes and Overall Patient Satisfaction with Treatment.

Abstract

Our aim was to investigate whether the surgical approach, i.e. endoscopic (ET) versus conventional/open thyroidectomy (ConT), contributes towards the improvement in quality of life (QoL), cosmetic outcomes and overall patient satisfaction with treatment. We conducted a prospective study (October 2016-August 2018) consisting of patients undergoing hemithyroidectomy for euthyroid, non-malignant solitary thyroid nodules (STNs). Patients were divided into two groups: Group I (ET)-41 patients and Group II (ConT)-52 patients. ET was performed via bilateral-axillo breast approach (BABA). A thyroid disease-specific questionnaire "ThyPRO-39hin" was used to evaluate pre- and post-operative QoL. Visual analogue scale (VAS) was used for post-operative pain. Cosmetic satisfaction, paraesthesia and overall satisfaction with treatment were evaluated using Likert-type verbal response scales. Pre- and post-operative scores (>6 months) were compared, and p value < 0.05 was considered significant. Mean age (p = 0.26), gender distribution (p = 0.07), mean tumour size (p = 0.74) and preoperative scores of QoL were comparable between the two groups. Post-operatively scores of symptom domain (p = 0.03), tiredness (p = 0.03), impaired social life (p = 0.03), cosmetic complaints (p =  < 0.001) and overall QoL (p =  < 0.001) were significantly better in Group I. Also, post-operative pain perception at first follow-up visit (p = 0.001) was lower in patients undergoing ET/Group I, with higher scar satisfaction scores (p =  < 0.001) and overall satisfaction with treatment (p =  < 0.001). Post-operative paraesthesia perception was comparable (p = 0.06) amongst the two groups. In this cohort study, patients undergoing endoscopic thyroid surgery reported superior post-operative QoL, cosmetic and overall satisfaction with treatment as compared to conventional/open thyroidectomy.
