Patterns, timing and consequences of post-thyroidectomy haemorrhage

INTRODUCTION Post-thyroidectomy bleeding is a low frequency but potentially life threatening event that is very difficult to predict. Given the increasing drive towards thyroidectomy with same day discharge, this study was conducted with the aim of identifying patterns, timing and consequences of post-thyroidectomy bleeding to assess the feasibility of day-case thyroidectomy. METHODS All patients who underwent a thyroidectomy between 2008 and 2015 at our institution were identified. Patterns, timing and consequences in all those who developed post-thyroidectomy bleeding were studied. RESULTS Of the 805 patients included in the study, 14 required re-exploration for bleeding; 7 (50%) of these within 8 hours of surgery, 6 (43%) between 18 and 30 hours, and 1 (7%) at 49 hours. Just under half (43%) of those with post-thyroidectomy bleeding had thyrotoxicosis. CONCLUSIONS A significant number of postoperative haemorrhages occurred beyond the immediate postoperative period. Same day discharge after thyroidectomy cannot therefore be recommended as a routine practice.
