Feasibility criteria for total thyroidectomy in outpatient surgery.

INTRODUCTION

France is pursuing a policy of cutting healthcare costs, and outpatient surgery is one of the objectives of this policy. Thyroid surgery could be suitable for outpatient management, provided there is an appropriate patient selection process. The aim of this study was to assess the risk factors for postoperative complications in total thyroidectomy (TT).

DESIGN

A single-center observational study was carried out from January 2010 to December 2015.

METHOD

Correlations between, on the one hand, age, gender, obesity, history of surgery, antiplatelet and/or anticoagulation treatment, the surgeon's experience, surgery time, repeated lymph node dissection, and surgical indication (cancer, lymphocytic thyroiditis, Graves' disease or multinodular goiter) and, on the other hand, onset of postoperative complications (postoperative hypocalcemia, uni- or bi-lateral lesions of the recurrent laryngeal nerves, and premature compressive hematoma) were assessed.

RESULTS

Four hundred and twenty-four consecutive TTs were included. 85 patients showed postoperative hypocalcemia (20.04%), 18 recurrent laryngeal nerve lesion (4.25%), and 4 compressive cervical hematoma (0.94%). Overall morbidity was 24.06%. Risk factors identified for postoperative hypocalcemia comprised: female gender [OR=3.2584; 95%CI (1.5500-7.7515); P=0.0036], surgery time [OR=1.0095; 95%CI (1.0020-1.0172); P=0.0129], and surgical indication for benign adenoma [OR=5.0642; 95%CI (1.7768-14.5904); P=0.0022]. None of the study variables emerged as risk factors for recurrent laryngeal nerve lesion. Repeated dissection increased the risk of re-do surgery for compressive hematoma [OR=25.1373; 95%CI (0.8468-32.2042); P=0.0347].

CONCLUSION

Surgery time, female gender, repeated dissection and total thyroidectomy for benign adenoma are risk factors that should be considered in decision-making for performing TT on an outpatient basis.
