Antiplatelet and Anticoagulant Medications Significantly Increase the Risk of Postoperative Hematoma: Review of over 4500 Thyroid and Parathyroid Procedures.

ABSTRACT: Antiplatelet and/or anticoagulant medication use is common. Abstinence a week before surgery may still result in altered hemostasis. The study aim was to report on perioperative antiplatelet and anticoagulant use in thyroidectomy and parathyroidectomy patients, and to determine the association with postoperative hematoma (POH) rates.Retrospective review of a prospective endocrine surgery database was performed. Procedure extent was defined as unilateral, bilateral, or extensive. Antiplatelets were categorized as none, 325 mg aspirin (ASA), <325 mg ASA, clopidogrel, or other. Anticoagulants were categorized as none, oral, or injectable.A total of 4514 patients were identified. POH developed in 22 patients (0.5 %). Rates were similar between age, gender, and reoperative status. POH were seven times more common after thyroidectomy (0.8 vs. 0.1 %, p < 0.01). Unilateral procedures had lower POH rates than bilateral or extensive (0.1 vs. 0.9 vs. 0.8 %, p < 0.01). POH rates in patients receiving 325 mg ASA (0.8 %) or clopidogrel (2.2 %) were much higher than patients not receiving antiplatelets (0.5 %) or receiving <325 mg ASA (0.1 %, p = 0.04). Oral anticoagulants (2.2 %) and injectable anticoagulants (10.7 %) had much higher POH rates than patients not receiving anticoagulants (0.4 %, p < 0.01). Target organ, patient gender, procedure extent, antiplatelet use, and anticoagulant use were included on logistic regression to determine association with POH. Bilateral procedures, thyroidectomy, clopidogrel, oral, and injectable anticoagulants were all independently associated with POH.POH occur more frequently after thyroidectomy and during bilateral procedures. Patients requiring clopidogrel or any anticoagulant coverage are at much higher risk for POH. These higher-risk patients should be considered for observation to ensure prompt POH recognition and intervention.

Project description:Importance:Vessel-sealant devices (VSDs) have been popularized for use in thyroid operations; however, the association of their use with postoperative neck hematoma, a rare but potentially fatal complication, has not been well studied. Objective:To examine the association of VSDs vs conventional hemostasis (CH) in thyroid operations with the development of neck hematoma. Design, Setting, and Participants:This retrospective cohort study evaluated 10?903 patients in the Thyroid Procedure-Targeted Database of the National Surgical Quality Improvement Program from January 1, 2016, to December 31, 2017. One-to-one nearest-neighbor propensity score matching was conducted to adjust for differences in baseline covariates, including demographics, comorbidities, indications for thyroid procedure (goiter, Graves disease, malignant and benign thyroid nodule), and several other thyroid-specific characteristics, between the VSD and CH groups. Main Outcomes and Measures:The primary outcome was postoperative hematoma requiring intervention with open evacuation, return to the operating room, tracheostomy, additional observation, or extended length of stay. Secondary outcomes include recurrent laryngeal nerve injury, operative duration, and hospital length of stay. Results:One-to-one propensity score matching yielded 6522 patients (mean [SD] age, 52 [15] years; 8544 [78.4%] female) with 3261 in each exposure group such that distribution of observed baseline covariates was not different between groups of the same propensity score. Within the matched cohort, CH was associated with higher odds of neck hematoma compared with VSD (odds ratio, 2.33; 95% CI, 1.55-3.49; P?<?.001), with 34 (1.0%) hematomas in the VSD group and 78 (2.4%) in the CH group. On the basis of this analysis, the number needed to treat with a VSD to prevent 1 postoperative hematoma was 74. Secondary outcomes included longer length of hospital stay (incidence rate ratio, 1.29; 95% CI, 1.23-1.36; P?<?.001]) in the CH group compared with the VSD group but no difference in the odds of recurrent laryngeal nerve injury (odds ratio, 0.90; 95% CI, 0.73-1.11; P?=?.32) or operative duration (incidence rate ratio, 0.99; 95% CI, 0.96-1.01; P?=?.24). Conclusions and Relevance:Use of VSDs during thyroid operations was associated with reduced odds of neck hematoma compared with CH techniques without increasing odds of nerve injury. The results suggest that postoperative neck hematoma rates after thyroid surgery may differ based on the hemostasis technique and that these differences should be considered when developing strategies for quality improvement of postoperative outcomes.

Project description:OBJECTIVE:We conducted this meta-analysis to assess the effectiveness of parathyroid gland autotransplantation in preserving parathyroid function during thyroid surgery for thyroid neoplasms. METHODS:We conducted a search by using PubMed, Embase, and the Cochrane Library electronic databases for studies that were published up to January 2019. The reference lists of the retrieved articles were also reviewed. Two authors independently assessed the methodological quality and extracted the data. A random-effects model was used to calculate the overall combined risk estimates. Publication bias was evaluated with a funnel plot using Egger's and Begg's tests. RESULTS:A total of 25 independent studies involving 10,531 participants were included in the meta-analysis. Compared with patients who did not undergo parathyroid gland autotransplantation, the overall pooled relative risks for patients who underwent parathyroid gland autotransplantation were 1.75 (95% CI: 1.51-2.02, p<0.001) for postoperative hypoparathyroidism, 1.72 (95% CI: 1.45-2.05, p<0.001) for protracted hypoparathyroidism, 1.06 (95% CI: 0.44-2.58, p = 0.894) and 0.71 (95% CI: 0.22-2.29, p = 0.561) for biochemical hypoparathyroidism and biochemical hypocalcemia at 6 months postoperatively, respectively, and 1.89 (95% CI: 1.33-2.69, p<0.001) and 0.22 (95% CI: 0.09-0.52, p = 0.001) for biochemical hypoparathyroidism and biochemical hypocalcemia at 12 months postoperatively, respectively. The pooled relative risks for patients who underwent one parathyroid gland autotransplantation and patients who underwent two or more parathyroid gland autotransplantations were 1.71 (95% CI: 1.25-2.35, p = 0.001) and 2.22 (95% CI: 1.43-3.45, p<0.001) for postoperative hypoparathyroidism, 1.09 (95% CI: 0.59-2.01, p = 0.781) and 0.55 (95% CI: 0.16-1.87, p = 0.341) for hypoparathyroidism at 6 months postoperatively compared with those of patients who did not undergo parathyroid gland autotransplantation. CONCLUSIONS:Parathyroid gland autotransplantation is significantly associated with increased risk of postoperative and protracted hypoparathyroidism, and the number of autoplastic parathyroid glands is positively correlated with the incidence of postoperative hypoparathyroidism.
