Laser speckle contrast imaging helps prevent hypoparathyroidism after thyroidectomy: Study
USA: Reports on the rates of hypoparathyroidism or hypocalcemia after thyroidectomy vary widely, However, numerous studies have shown that identifying the glands alone is insufficient to improve hypocalcemia rates post-thyroidectomy.
A new study by Emmanuel A. Mannoh and the team has reported that Laser speckle contrast imaging (LSCI) is a promising technique and has the potential to help reduce the incidence of hypocalcemia after thyroidectomy as it provides surgeons with additional information during surgery to aid in the preservation of parathyroid function. This study is published in Thyroid journal.
The objective of the study was to establish a speckle contrast threshold for classifying a parathyroid gland as adequately perfused and evaluate the relationship between intraoperative LSCI measurements and postoperative outcomes of total thyroidectomy patients.
The study included 72 thyroidectomy patients. After thyroid resection, an LSCI device was used to image all parathyroid glands identified, and a speckle contrast value was calculated for each. An average value was calculated for each patient, and the data were grouped according to whether the patient had normal (16–77 pg/mL) or low levels of parathyroid hormone (PTH) measured on postoperative day 1 (POD1).
