Risk factors for post-thyroidectomy haemorrhage: a meta-analysis.

TLDR
A systematic review identified a number of risk factors for post-thyroidectomy haemorrhage, including older age, male sex, Graves' disease, antithrombotic agents use, bilateral operation, neck dissection and previous thyroid surgery.
Abstract
BACKGROUND Post-thyroidectomy haemorrhage is a rare but potentially life-threatening and unpredictable complication of thyroid surgery. In this study, we analysed the potential risk factors for the occurrence of post-thyroidectomy haemorrhage. METHODS The PubMed and SCIE databases were comprehensively searched for studies published before June 30, 2016. Studies on patients who underwent an open thyroidectomy with or without neck dissection were included, and RevMan 5.3 software was used to analyse the data. RESULTS Twenty-five studies and 424 563 patients were included in this meta-analysis, and post-thyroidectomy haemorrhage occurred in 6277 patients (incidence rate = 1.48%). The following variables were associated with an increased risk of post-thyroidectomy haemorrhage: older age (MD = 4.30, 95% CI = 3.09-5.52, P < 0.00001), male sex (OR = 1.73, 95% CI = 1.54-1.94, P < 0.00001), Graves' disease (OR = 1.76, 95% CI = 1.44-2.15, P < 0.00001), antithrombotic agents use (OR = 1.96, 95% CI 1.55-2.49, P < 0.00001), bilateral operation (OR = 1.71, 95% CI = 1.50-1.96, P < 0.00001), neck dissection (OR = 1.53, 95% CI = 1.11-2.11, P = 0.01) and previous thyroid surgery (OR = 1.62, 95% CI = 1.12-2.34, P = 0.01). Malignant tumours (OR = 1.07, 95% CI = 0.89-1.28, P = 0.46) and drainage device use (OR = 1.27, 95% CI = 0.74-2.18, P = 0.4) were not associated with post-thyroidectomy haemorrhage. CONCLUSION Our systematic review identified a number of risk factors for post-thyroidectomy haemorrhage, including older age, male sex, Graves' disease, antithrombotic agents use, bilateral operation, neck dissection and previous thyroid surgery. Early control of modifiable risk factors could improve patient outcomes and satisfaction.

Reoperation for Bleeding After Thyroid and Parathyroid Surgery: Incidence, Risk Factors, Prevention, and Management.

TL;DR: A higher risk profile for significant post-operative bleeding cannot be determined in patients undergoing thyroid surgery and protocols to reduce the risk of bleeding and for the early detection and management of bleed are developed.

May predictors of difficulty in thyroid surgery increase the incidence of complications? Prospective study with the proposal of a preoperative score.

TL;DR: Predictors of difficulty in thyroidectomy did not affect morbidity rates, as suggested by previous studies, but only operative times, which were significantly increased in patients with higher score, allow the fundamental role of a systematic use of optical magnification and microsurgical technique to be confirmed.

Post-thyroidectomy bleeding: analysis of risk factors from a national registry.

TL;DR: In this article, the authors reviewed the best available UK data to evaluate a recent change in this recommendation and found that the highest risk for bleeding occurred following total thyroidectomy in men, but overall bleeding was unpredictable.
Journal ArticleDOI

Narrative review of management of thyroid surgery complications.

TL;DR: In this article, the authors discuss the prevention, recognition and therapy of intraoperative and postoperative complications in thyroid surgery and discuss the potential negative effects that complications may have on patients' quality of life.

The Newcastle-Ottawa Scale (NOS) for Assessing the Quality of Nonrandomised Studies in Meta-Analyses

TL;DR: The Newcastle-Ottawa Scale (NOS) as discussed by the authors was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the quality assessments in the interpretation of meta-analytic results.

Critical evaluation of the Newcastle-Ottawa scale for the assessment of the quality of nonrandomized studies in meta-analyses

TL;DR: The quality assessment of non-randomized studies is an important component of a thorough meta-analysis of non randomized studies and can dramatically influence the interpretation of meta-analyses, and can even reverse conclusions regarding the effectiveness of an intervention.
