RESUMO
Outpatient thyroidectomy has become slowly accepted with various published reports predominantly examining partial or subtotal thyroidectomy. Concerns regarding the safety of outpatient total and completion thyroidectomy remain, especially with regard to vocal fold paralysis, hypocalcemia, and catastrophic hematoma. We aimed to evaluate the safety of outpatient thyroid surgery in a large cohort by retrospectively comparing outcomes in those who underwent outpatient (n = 251) versus inpatient (n = 291) completion or total thyroidectomy between February 2009 and February 2015. Outpatient completion and total thyroidectomy had lower rates of temporary hypocalcemia (6% vs 24.4%; P < 0.001) and no significant difference in rates of return to emergency department (1.2% vs 1.4%), hematoma formation (0.8% vs 0.7%), temporary (2% vs 4.1%) or permanent (0.4% vs 0.7%) vocal fold paralysis, or permanent hypocalcemia (0.4% vs 0%) compared with the inpatient group. Outpatients requiring calcium replacement had shorter duration of postoperative calcium supplementation (44.4 ± 59.3 days vs 63.3 ± 94.4 days; P < 0.001). Our data demonstrate similar safety in outpatient and inpatient total and completion thyroidectomy.

After thyroid surgery, protocols based on postoperative parathyroid hormone (PTH) levels may prevent symptoms of hypocalcemia, while avoiding unnecessary prophylactic calcium and/or vitamin D supplementation. We examined the value of an initial management protocol based solely on a single PTH level measured one hour after completion or total thyroidectomy to prevent symptomatic hypocalcemia by conducting a retrospective review of 697 consecutive patients treated from July 2003 to April 2015. The proportion of patients who developed symptomatic hypocalcemia was similar between those treated before (n = 155) and after (n = 542) implementation of this 1-hour PTH protocol (16.8% vs 15.9%; P = 0.786). Those in the 1-hour PTH groups had lower overnight observation rates (97.4% vs 53.7%; P < 0.001) and length of stay (1.98 ± 2.61 vs 0.89 ± 1.87 days; P < 0.001), and required less calcium (3.9% vs 0.8%; P = 0.015) and vitamin D (2.6% vs 0%; P = 0.002) supplementation one year after surgery. Less than 1 per cent of patients discharged on the day of surgery in accordance with the 1-hour PTH guidelines returned to the emergency room for symptomatic hypocalcemia; none experienced significant morbidity. This protocol facilitates early discharge of low-risk patients and results in a similar or improved postoperative course compared with traditional overnight observation.
