Post thyroidectomy thyroid tissue remnant: Comparison between tie ligation and LigaSure by post-operation ultrasonography and technetium uptake

Introduction: Thyroidectomy can be done using different methods. In this study, post thyroidectomy thyroid remnant was compared between tie ligation and LigaSure.Methods: Thirty-two patients undergoing thyroidectomy were equally grouped into tie ligation (A) and LigaSure (B). The duration of operation, estimated surgical blood loss, drain discharge, pre and post-operation calcium and parathormone levels, and pre and post-operation subjective assessment of the vocal cord function were collected. Thyroid bed technetium uptake (TTU) and ultra-sonographies were done, respectively, within ۳ and ۷-۱۴ days after surgery, and thyroid tissue remnant was evaluated.Results: Duration of the operation was longer in group A. Surgery-related blood loss and drain discharge, changes of calcium,  parathormone and quality of voice before and after surgery were similar between the two groups. Three patients had sonographically remarkable post-surgical thyroid remnant; all operated by tie ligation, the difference with group B was insignificant. TTU was similar between groups A and B.Conclusion: Although LigaSure reduces the operation time with similar operation outcomes, the indicators of thyroid tissue surgical remnants are similar between the two sterategies.
