The application of subcapsular saline injection during bilateral axillo-breast approach robotic thyroidectomy: a preliminary report

Abstract

PurposeSaving the parathyroid gland during robotic thyroidectomy is challenging. This study evaluated the application of a novel method, subcapsular saline injection (SCASI), to save the parathyroid gland during bilateral axillo-breast approach (BABA) robotic total thyroidectomy.MethodsOf the 81 included patients operated on from 2014 to 2016, 31 and 50 underwent BABA robotic total thyroidectomy with and without SCASI, respectively. Serum concentrations of parathyroid hormone (PTH), calcium, and ionized calcium were measured at 1day and 9 months postoperatively. Transient hypoparathyroidism was defined as PTH<10.0pg/mL after 1day and permanent hypoparathyroidism as PTH<15.0pg/mL at 9 months.ResultsThere were no significant clinicopathologic differences between the two groups. The rate of transient hypoparathyroidism was significantly lower in the SCASI group than in the non-SCASI group [16.1% (5/31) vs. 44% (22/50), p<0.01]. However, the rates of permanent hypoparathyroidism [0% (0/31) vs. 4% (2/50), p=0.699] did not differ significantly.ConclusionsSCASI is a feasible and safe method of saving the parathyroid gland during BABA robotic total thyroidectomy.
