RESUMO
OBJECTIVE: To investigate the visual outcomes and optimal timing for repeat surgery in cases of postoperative hematoma following transsphenoidal surgery for pituitary neuroendocrine tumors (PitNETs). METHODS: A retrospective study was conducted on 28 patients who developed evident postoperative hematoma out of a total of 9,010 patients. The hematomas were classified into three types based on their CT appearance. Type 1a - mild high density with no tension, Type 1b - thin-layer high density; Type 2a - solid high density with large empty cavities, Type 2b - solid high density with small empty cavities; Type 3 -solid high density with no cavity showing high tension. Patient data were collected for analysis. RESULTS: The study cohort comprised 10 female and 18 male patients, with a mean age of 51.5±11.9 years. Most patients presented with large adenomas (median diameter 36mm). Postoperative visual sight improved in 12 patients, remained stable in 11 patients, and worsened in 5 patients. Notably, no patients experienced worsened visual sight beyond twenty-four hours after the operation. Among the five patients with visual deterioration, four had CT type 3 hematoma (4/6, 66.7%), and one had CT type 2b hematoma (1/9, 11.1%). Patients in the type 3 CT group were significantly more prone to experience visual deterioration compared to those in the type 2 group (odds ratio [OR] 2.154 [95% CI 1.858-611.014], P=.027). Four patients underwent repeat surgery after visual deterioration, resulting in visual improvement following a prolonged recovery period. Postoperative hematoma had limited impact on pituitary dysfunction and hyponatremia. CONCLUSION: Our study reveals a significant association between postoperative hematoma CT types and visual deterioration. For patients with stable visual sight and type 1 or 2a hematoma, conservative strategies may be considered. Conversely, type 2b and 3 patients are at higher risk of visual deterioration, especially within the first 24 hours after the operation. Consequently, early reoperation before vision worsens may be a prudent approach to reduce risks and improve visual outcomes, particularly in type 3 patients.

BACKGROUND: Controversy remains with the use of post-operative subfascial drains for anterior cervical discectomy and fusion, with limited guidelines and a paucity of conclusive evidence. Thus, the aim of this meta-analysis was to analyse and collate an evidence summary to determine the efficacy of such drains. METHODS: A systematic search of Medline (2002-2022.11), PubMed (2003-2022.11), Scopus (2002-2022.11), Cochrane Library (2015-2022.11) databases and reference lists of articles was conducted as per Cochrane systematic reviews standards. All relevant RCTs and NRCTs were included in this study. Data was extracted in a standardised form and analysed with RevMan version 5.4.1. Bias was assessed with RoB2 tool for RCTs and ROBINS-E tool for NRCTs. RESULTS: Two RCTs (136 patients) and five NRCTs (7563 patients) were included. These had a moderate to high risk of bias, except for one very high-risk article. Meta-analysis results showed no significant differences for post-operative haematoma (P = 0.31), surgical site infection (P = 0.84), take back to theatre (P = 0.27), length of stay (P = 0.34), and estimated blood loss (P = 0.09). Dysphagia (P = 0.002) and median operative time (P = 0.02) were significantly increased in the drain cohort. CONCLUSION: The low quality of available data in the included studies is insufficient to estimate the effect of post-operative drains for elective spondylotic ACDF. The findings suggest that if the decision to leave a drain in is left to the surgeon, then there is no difference in the rates of POH, SSI, LOS, or take back to the theatre. The significant association of dysphagia and increased operative time with drains, and the non-significant trend towards increased EBL with drains, must be considered in the context in which procedures may influence the decision to place drains. The results could not be stratified by various confounders that affect the decision-making process, including the number of levels operated. Due to the decreased quality and amount of evidence available, large-scale RCTs that adequately account for confounders should be performed.

BACKGROUND: Surgical removal of a vestibular schwannoma is a complex and challenging procedure, which may be complicated by development of postoperative hematomas, particularly after incomplete resection of the tumor. OBJECTIVE: To investigate the occurrence of postoperative intra- or peritumoral hematomas after surgery for a vestibular schwannoma. METHODS: This retrospective study evaluated 49 patients (age range 17-78 years) with a vestibular schwannoma, who were treated surgically via the lateral suboccipital approach between 2011 and 2016. The tumors ranged in size from 0 mm (in a case of an intracanalicular lesion) to 56 mm. In 30 cases (61%), total or near-total resection was accomplished, and in 19 cases (39%), subtotal or partial resection was done. On the basis of their bleeding tendency during tumor removal, the patients were divided into a "less-bleeding" (38 cases; 78%) and a "more-bleeding" (11 cases; 22%) subgroups. RESULTS: A maximal vestibular schwannoma diameter >30 mm, patient age >60 years, and more bleeding during tumor removal were significantly associated with incomplete (subtotal or partial) resection. In six cases (12%), serial computed tomography after surgery demonstrated a postoperative hematoma, which was caused by insufficient irrigation of the surgical field (in two cases) or resulted from peritumoral hemorrhage (in two cases), intratumoral hemorrhage (in one case), or both intra- and peritumoral hemorrhage (in one case). The latter patient required urgent reoperation. In all cases, postoperative hematomas occurred after incomplete (subtotal or partial) resection of a vestibular schwannoma, and their development was significantly associated with more bleeding during tumor removal. CONCLUSION: For avoidance of postoperative hematomas, careful hemostasis is required after completion of vestibular schwannoma removal, especially in cases with incomplete resection and an excessive bleeding tendency of the tumor tissue.

Anterior cervical discectomy and fusion (ACDF) is the most common surgery performed on the cervical spine, and the number of its cases has tripled over the last two decades. Although this intervention is typically safe and effective, it carries an inherent complication risk, which should not be underestimated. Improvements in surgical techniques and advances in interbody fusion devices and plating systems have certainly reduced the rate of postoperative morbidity, but despite such progress, surgeons need to beware consistently of the potential complications, inform the patient of their possibility, and have a management strategy as they develop. This review discusses postoperative morbidity encountered in recently reported large studies on ACDF and highlights the senior author's own single-surgeon experience with 2579 such procedures performed between 1998 and 2017. In his clinical series, which is the largest one reported to date, the overall complication rate was 7.0% (180 cases), and dysphagia (1.9% of cases), graft/hardware failures (1.3% of cases), and postoperative hematomas (0.9% of cases) were noted most frequently. Understanding of the risk and clinical impact of complications after ACDF is very important and every effort should be put on their possible avoidance and on appropriate management when they do occur.

BACKGROUND: Hematoma after thyroid surgery is a serious complication. The purpose of this study was to determine the predictors and consequences of hematoma after thyroid surgery. MATERIALS AND METHODS: A retrospective analysis of 11,552 open thyroidectomies was conducted using the American College of Surgeons National Surgical Quality Improvement Program 2016-2017 main and thyroidectomy-targeted procedure databases. Predictors of hematoma and the effect of hematoma on outcomes were analyzed by multivariate logistic regression, resulting in risk-adjusted odds ratios of hematoma and morbidity/mortality, respectively. Statistical analysis was performed using R version 3.5.1. RESULTS: We found that male gender (odds ratio 1.71, 95% confidence interval 1.25-2.32; P value 0.0007), Black race (1.89, 1.27-2.77; 0.0014), other race (1.76, 1.23-2.50; 0.0017), hypertension (1.68, 1.20-2.35; 0.0026), diabetes (1.45, 1.00-2.06; 0.0460), and bleeding disorders (3.63, 1.61-7.28; 0.0007) were independent risk factors for postoperative hematoma. The use of an energy device for hemostasis (0.63, 0.46-0.87; 0.0041) was independently associated with decreased hematoma rate. Postoperative hematoma was an independent risk factor for overall morbidity (3.04, 2.21-4.15; <0.0001), hypocalcemia (1.73, 1.08-2.66, 0.0162), recurrent laryngeal nerve injury (2.42, 1.57-3.60, <0.0001), pulmonary morbidity (18.91, 10.13-34.16, <0.0001), wound morbidity (10.61, 5.54-19.02, <0.0001), readmission (5.23, 3.34-7.92, <0.0001), return to operating room (90.73, 62.62-131.97; <0.0001), and length of stay greater than the median (5.10, 3.62-7.15, <0.0001). CONCLUSIONS: Identified by this study are the predictors of postthyroidectomy hematoma and the consequences thereof. Notably, the use of energy devices for hemostasis was shown to be protective of postoperative hematoma. The results of this study may guide pre- and intra-operative decision-making for thyroidectomy to reduce rates of postoperative hematoma.

Gender dysphoria is a condition in which a discrepancy between biological sex and gender identity causes distress. Many female-to-male transsexuals (FTMTS) are uncomfortable with female breasts. Chest wall contouring surgery is effective for obtaining a male-type chest, reducing mental stress, and increasing sexual satisfaction in such cases. At the Okayama University Hospital Gender Center, we have obtained positive results using an algorithm to determine the most appropriate surgical method for chest wall contouring in FTMTS patients. However, serious complications requiring reoperation, such as hematoma, may still occur. Postoperative hematomas were found in 15 (4.18%) of 358 FTMTS patients who underwent chest contouring surgery at our hospital between 2006 and 2018. Postoperative hematoma was examined retrospectively. The median time to the onset of hematoma was 7 (6-12) h after the initial surgery. The main blood vessels causing bleeding were those in the head-side skin flap region where visual confirmation was difficult and the perforator vessels from the pectoralis major muscle. Intraoperative bleeding and the operation time had a significant impact on the onset of postoperative hematoma. This is the first retrospective study that investigated the blood vessels and other factors contributing to postoperative hematoma development after chest wall contouring.

BACKGROUND: Neck hematoma is a complication of carotid endarterectomy, usually occurring in the comparatively early stage postoperatively. CASE PRESENTATION: We described a patient developing life-threatening hemorrhage and non-clotting hematoma at a comparatively later stage after CEA. DIC was diagnosed according to the lab results, and the patient underwent re-operation and was supported with blood products until the coagulopathy was corrected. The patient had a history of prostatic hyperplasia and experienced malaise during the hospitalization. Prostate cancer with bone metastases was diagnosed. CONCLUSIONS: This case report describes a rare underlying cause of hematoma after CEA, which reminds us to pay attention to prostate symptoms or related medical history, especially malignancy, in surgical patients, which may result in severe complications.

BACKGROUND: Postoperative cervical hematoma (PCH) after thyroid and parathyroid surgery is a well-known complication. This study used data from the Nationwide Inpatient Sample to identify risk factors, estimate mortality, length of stay (LOS), and total costs attributable to PCH in patients undergoing procedures for thyroid and parathyroid diseases. METHODS: Patients aged >18 y who underwent thyroid or parathyroid surgery between 2001 and 2011 were identified and stratified by the occurrence of PCH. Univariate analyses of patient demographics, clinical and hospital characteristics were performed. Multivariable logistic regression was used to determine risk factors for hematoma formation. LOS and costs were fit to linear regression models to determine the effect of PCH after adjusting for patient and hospital characteristics. RESULTS: Of patients who underwent thyroid or parathyroid surgery, 619 patients (0.8%) had a PCH. Predisposing factors included nonelective admission (emergent: OR = 2.01, P < 0.0001; urgent: OR = 1.47, P = 0.003), diagnosis of Graves' disease (OR = 1.90, P < 0.0001), or other benign pathology (OR = 1.43, P = 0.011) and having ≥2 comorbidities (2-3 comorbidities, OR = 1.24; P = 0.036 and ≥ 4 comorbidities, OR = 2.28; P < 0.0001). After adjusting for those characteristics, the total excess LOS and costs attributable to PCH were 2.1 d (P < 0.0001) and $7316 (P < 0.0001), respectively. In addition, after risk adjustment, odds of mortality more than tripled (P < 0.0001) in the setting of PCH. CONCLUSIONS: Because risk for PCH is largely driven by preoperative patient risk factors, five clinicians have an opportunity to stratify patients accordingly and thereby minimize the resource utilization and health care spending among those with lowest risk.

BACKGROUND: We recently sensed an increase in the frequency of groin hematoma after inguinal hernia repair (IHR) at our institution. The aim of this study was to provide a more updated assessment of the risk factors inherent to this complication. METHODS: We performed a case-control study of all adult patients (age ≥ 18 y) who developed a groin hematoma after IHR at our institution between 2003 and 2015. Univariate and multivariable analyses were performed to assess for independent predictors for groin hematoma. RESULTS: A total of 96 patients (among 6608 IHR) developed a groin hematoma, (60 were observed, 36 required intervention). The hematoma frequency increased from our previous study (1.4 % versus 0.9%, P < 0.01). Mean age was 64.6 y (range: 18-92), and 84.3% were men. There was no significant difference in the laterality, type, or technique of IHR between cases and controls. Univariate analysis (odds ratio [95% confidence interval], P) identified warfarin usage (3.5, [1.6-6.4], P < 0.01), valvular heart disease (11.6, [2.6-51.3], P < 0.01), atrial fibrillation (2.6, [1.2-5.5], P = 0.01), hypertension (2.03, [1.1-3.6], P = 0.02), recurrent hernia (3.7, [1.4-9.7], P < 0.01), and coronary artery disease (2.1, [1.0-4.4 ], P = 0.05) as significant preoperative factors. The proportion of patients on warfarin decreased since our prior report (31% versus 42%, P = 0.20). On multivariable regression, warfarin and recurrent hernia were independent predictors of hematoma development. CONCLUSIONS: Independent risk factors for the development of groin hematoma after IHR included warfarin use and recurrent hernia. Careful consideration for anticoagulation and surgical hypervigilance remains prudent in all patients undergoing IHR and especially those with recurrence.

PURPOSE: This multicenter retrospective study focuses on understanding the incidence, causative bacteria, and risk factors for Periprosthetic Joint Infection (PJI) following hemiarthroplasty in elderly patients with displaced femoral neck fractures (FNF). METHODS: From 2016 to 2020, 1,619 patients were diagnosed with displaced FNFs and treated surgically across 11 centers. After exclusions, 1,438 patients (399 men and 1,039 women) were included in the study, averaging 82.1 years in age and 20.2 kg/m² in BMI, observed over 25.7 months on average. Data on demographics, medical history, surgical details, and complications were described. RESULTS: PJI occurred in 20 of the 1438 patients (1.4%). The causative organism was methicillin-susceptible Staphylococcus aureus in 6 patients and methicillin-resistant S. aureus in 6 patients. In patients' backgrounds, the average age was slightly higher in the non-PJI group (82.1 years) compared to the PJI group (80.4 years). There was a higher percentage of males in the PJI group (45%) than in the non-PJI group (27.5%). Drug history showed that the prevalence of anticoagulant use in the PJI group was 25%. Peripheral vascular disease and diabetes mellitus were more prevalent in the PJI group. Most patients in both groups were independent in daily activities. The blood transfusion rate was significantly higher in the PJI group (50%) than in the non-PJI group (23.8%). Notably, the incidence of hematoma was higher in the PJI group (40%). CONCLUSION: This multicenter retrospective study demonstrates a low incidence (1.4%) of PJI in elderly patients undergoing hemiarthroplasty for FNF, primarily due to Staphylococcus aureus. Increased usage of antiplatelets and anticoagulants, as well as comorbidities related to atherosclerosis, like peripheral vascular disease and diabetes mellitus, were observed in patients with PJI. Additionally, these patients experienced higher rates of blood transfusion and postoperative hematomas, highlighting the need for careful management. It should be noted, however, that this finding is a conclusion limited by study design issues, including the retrospective design, small PJI sample size, and variability in treatment approaches.

PURPOSE: Delayed facial palsy (DFP) is a rare postoperative complication after vestibular schwannoma (VS) surgery. The exact mechanism of DFP remains uncertain and the risk factors for DFP are still controversial. The authors aimed to investigate the characteristics, risk factors, and etiology of DFP after VS resection retrospectively. METHODS: Ninety-one consecutive surgeries with VS were analyzed. Patients with neurofibromatosis 2 in eight surgeries and postoperative facial palsy House-Brackmann (HB) grade more than 3 in two surgeries were excluded. Eighty-one surgeries were included in this research. Facial nerve function was evaluated using the HB grade. Delayed facial palsy was defined as deterioration in the facial function of at least 1 HB grade more than 1 day after undergoing VS resection. The characteristics of patients with VS and risk factors for DFP were analyzed. RESULTS: All surgeries were performed via a retrosigmoid approach. DFP was observed in nine patients. There were no statistically significant differences between the DFP group and non-DFP group in terms of the following characteristics: sex, age, side, size, Koos grading system, postoperative facial palsy, or extent of resection. Postoperative hematoma in the cerebellopontine angle (CPA) cistern was significantly higher in the DFP group than in the non-DFP group (p = 0.0023), and was significantly associated with DFP after VS surgery (odds ratio 18.40, p < 0.001). DFP improved in seven patients, but two patients did not improve. CONCLUSION: DFP occurred in 11.1% of patients after VS surgery. This study revealed that postoperative hematoma in the CPA cistern was significantly associated with DFP after VS surgery.

Background: Studies analyzing the incidence and clinical implications of postoperative hematomas after total hip arthroplasty (THA) remain limited. The purpose of the present study was to use the National Surgical Quality Improvement Program (NSQIP) dataset to determine rates, risk factors, and subsequent complications of postoperative hematomas requiring reoperation after primary THA. Methods: Study population included patients who underwent primary THA (CPT code: 27130) from 2012-2016 recorded in NSQIP. Patients who developed a hematoma requiring reoperation in the 30-day postoperative period were identified. Multivariate regressions were created to identify patient characteristics, operative variables, and subsequent complications that were associated with a postoperative hematoma requiring reoperation. Results: Among the 149,026 patients who underwent primary THA, 180 (0.12%) developed a postoperative hematoma requiring reoperation. Risk factors included body mass index (BMI) ≥ 35 (relative risk [RR]: 1.83, P = .011), American Society of Anesthesiologists (ASA) class ≥3 (RR: 2.11, P < .001), and history of bleeding disorder (RR: 2.71, P < .001). Associated intraoperative characteristics were an operative time ≥100 minutes (RR: 2.03, P < .001) and use of general anesthesia (RR: 1.41, P = .028). Patients developing a hematoma requiring reoperation were at higher risk of subsequent deep wound infection (RR: 21.57, P < .001), sepsis (RR: 4.3, P = .012), and pneumonia (RR: 3.69, P = .023). Conclusions: Surgical evacuation for a postoperative hematoma was performed in about 1 in 833 cases of primary THA. Several nonmodifiable and modifiable risk factors were identified. Given the 21.6 times increased risk of subsequent deep wound infection, select, at-risk patients may benefit from closer monitoring for signs of infection.
RESUMO
Objective: To explore if antiplatelet or anticoagulant therapy increases the risk of transfusion requirement or postoperative hematoma formation in patients undergoing microvascular reconstruction for head and neck defects. Study Design: Retrospective cohort study. Setting: Departments of Otolaryngology-Head and Neck Surgery at the University of Alabama at Birmingham, the University of Colorado, and the University of California Irvine. Methods: A multi-institutional, retrospective review on microvascular reconstruction of the head and neck between August 2013 to July 2021. Perioperative antithrombotic data were collected to examine predictors of postoperative transfusion and hematoma. Results: A total of 843 free flaps were performed. Preoperative hemoglobin, hematocrit, operative time, and flap type were positive predictors of postoperative transfusion in both bivariate (P < .0001) and multivariate analyses (P < .0001). However, neither anticoagulation nor antiplatelet therapy were predictive of postoperative transfusion rates and hematoma formation. Conclusion: Antithrombotic regimens do not increase the risk of postoperative transfusion or hematoma in head and neck microvascular reconstruction. Based on this limited data, perioperative antithrombotic regimens can be considered in patients who may otherwise be at risk for these postoperative complications.
RESUMO
OBJECTIVE: Studies discussed few risk factors for specific patients, such as duration of disease; or surgical factors, such as duration and time of surgery; or C3 or C7 involvement, which could have led to the formation of hematomas (HTs). To investigate the incidence, risk factors especially the factors mentioned above, and management of postoperative HTs following anterior cervical decompression and fusion (ACF) for degenerative cervical diseases. METHODS: Medical records of 1,150 patients who underwent ACF for degenerative cervical diseases at our hospital between 2013 and 2019 were identified and reviewed. Patients were categorized into the HT group (HT group) or normal group (no-HT group). Demographic, surgical and radiographic data were recorded prospectively to identify risk factors for HT. RESULTS: Postoperative HT was identified in 11 patients, with an incidence rate of 1.0% (11 of 1,150). HT occurred within 24 hours postoperatively in 5 patients (45.5%), while it occurred at an average of 4 days postoperatively in 6 patients (54.5%). Eight patients (72.7%) underwent HT evacuation; all patients were successfully treated and discharged. Smoking history (odds ratio [OR], 5.193; 95% confidence interval [CI], 1.058-25.493; p = 0.042), preoperative thrombin time (TT) value (OR, 1.643; 95% CI, 1.104-2.446; p = 0.014) and antiplatelet therapy (OR, 15.070; 95% CI, 2.663-85.274; p = 0.002) were independent risk factors for HT. Patients with postoperative HT had longer days of first-degree/intensive nursing (p < 0.001) and greater hospitalization costs (p = 0.038). CONCLUSION: Smoking history, preoperative TT value and antiplatelet therapy were independent risk factors for postoperative HT following ACF. High-risk patients should be closely monitored through the perioperative period. Postoperative HT in ACF was associated with longer days of first-degree/intensive nursing and more hospitalization costs.
RESUMO
STUDY DESIGN: Narrative Review. OBJECTIVE: To provide an overview of etiology and risk factors of airway complications after anterior cervical spine surgery (ACSS). METHODS: A search was performed in PubMed and adapted for use in other databases, including Embase, Cochrane Library, Cochrane Register of Controlled Trials, Health Technology Assessment database, and NHS Economic Evaluation Database. RESULTS: 81 full-text studies were reviewed. A total of 53 papers were included were included in the review and an additional four references were extracted from other references. 39 papers were categorized as etiology and 42 as risk factors. CONCLUSIONS: Most of the literature on airway compromise after ACSS is level III or IV evidence. Currently, there are no systems in place to risk-stratify patients undergoing ACSS regarding airway compromise or guidelines on how to manage patients when these complications do occur. This review focused on theory, primarily etiology and risk factors.
RESUMO
Background: Delirium is characterized by acute brain dysfunction. Although delirium significantly affects the quality of life of patients with brain metastases, little is known about delirium in patients who undergo craniotomy for brain metastases. This study aimed to identify the factors influencing the occurrence of delirium following craniotomy for brain metastases and determine its impact on patient prognosis. Method: A total of 153 patients who underwent craniotomy for brain metastases between March 2013 and December 2020 were evaluated for clinical and radiological factors related to the occurrence of delirium. Statistical analysis was conducted by dividing the patients into two groups based on the presence of delirium, and statistical significance was confirmed by adjusting the clinical characteristics of the patients with brain metastases using propensity score matching (PSM). The effect of delirium on patient survival was subsequently evaluated using Kaplan-Meier analysis. Results: Of 153 patients, 14 (9.2%) had delirium. Age (P = 0.002), sex (P = 0.007), and presence of postoperative hematoma (P = 0.001) were significantly different between the delirium and non-delirium groups. When the matched patients (14 patients in each group) were compared using PSM, postoperative hematoma showed a statistically significant difference (P = 0.036) between the delirium and non-delirium groups. Kaplan-Meier survival analysis revealed that the delirium group had poorer prognosis (log-rank score of 0.0032) than the non-delirium group. Conclusion: In addition to the previously identified factors, postoperative hematoma was identified as a strong predictor of postoperative delirium. Also, the negative impact of delirium on patient prognosis including low survival rate was confirmed.
RESUMO
Over the past decade, the use of neuromonitoring in thyroid surgery has become well established and is increasing accepted across the world. In addition, new developments in energy devices have significantly improved efficacy in achieving hemostasis in thyroid surgery. Few studies focused on the complication rates in energy device-assisted sutureless neuro-monitored thyroidectomy. This study investigates a novel LigaSure Small Jaw (LSJ) technique for sutureless thyroidectomy and compares the surgical complication rates between LSJ and conventional clamp-and-tie technique in one thousand consecutive neuro-monitored thyroidectomy patients. Five hundred patients received sutureless thyroidectomy performed with LSJ (Group L), and 500 patients received surgery performed with conventional clamp-and-tie technique (Group C). Complication rates of postoperative hematoma, hypocalcemia and recurrent laryngeal nerve (RLN) palsy were compared between groups. The overall complication rates of hematoma, hypocalcemia (temporary/ permanent), and RLN (temporary/ permanent) palsy were 0.9%, 24.9% (24.6%/0.3%), and 1.7% (1.5%/0.2%), respectively. Group L and Group C significantly differed in postoperative hematoma rate (0.0% vs. 1.8%, respectively; p = 0.0026) and in postoperative hypocalcemia rate (20.1% vs. 30.0%, respectively; p = 0.0032). The incidence of RLN palsy did not significantly differ between Group L and Group C (1.38% vs. 2.08%; p = 0.2652). The overall surgical complication rates are low in neuro-monitored thyroidectomy. The LSJ is feasible for performing completely sutureless thyroidectomy and obtains superior outcomes of postoperative hematoma and hypocalcemia in comparison with clamp-and-tie hemostatic technique. The novel LSJ technique using double or overlapped sealing is useful for sutureless thyroidectomy. However, surgeons must carefully observe the tissue contraction that may reduce the LSJ-RLN distance and increase the risk of thermal injury during the LSJ activation.

OBJECTIVES/HYPOTHESIS: Performance of thyroidectomy on an outpatient basis has gained popularity although many jurisdictions have not shifted their practice despite a strong safety profile. We sought to assess the uptake and safety of outpatient thyroidectomy in Ontario. STUDY DESIGN: Retrospective cohort study. METHODS: This was a population-based retrospecive cohort of adult patients undergoing hemithyroidectomy or total thyroidectomy between 1993 and 2017 in Ontario, Canada. Outpatient surgery was defined as discharge home on the same day of surgery. Outcomes of interest include 30-day all cause death, hematoma, emergency department use, and readmission. To adjust for confounding, propensity scores were calculated. Logistic regression models with inverse probability of treatment weighting (IPTW) were then used to estimate the exposure-outcome relationship. RESULTS: The final cohort consisted of 81,199 patients: 8,442 underwent same day surgery and 72,757 were admitted. The proportion of patients undergoing outpatient thyroidectomy increased overtime (2.3% in 1993-1994 to 17.8% in 2016-2017). Factors associated with higher odds of outpatient thyroidectomy included: younger age, less material deprivation, less comorbidities, and higher surgeon volume. The absolute number of deaths (≤5) and hematomas (64, 0.8%) in the outpatient cohort was low. After IPTW adjustment, patients with outpatient management had lower odds of neck hematoma (OR 0.73[95CI% 0.58-0.93)], but higher odds of emergency department use (OR 1.67[95%CI 1.56-1.79]). CONCLUSIONS: Outpatient thyroidectomy is not associated with an increased mortality risk. Less than one in five patients undergo outpatient thyroidectomy in Ontario, despite a well-established safety profile. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:2625-2633, 2021.

BACKGROUND: Hemostasis plays an important role in safe brain tumor resection and also reduces the risk for surgical complications. This study aimed to evaluate the efficacy of FLOSEAL®, a topical hemostatic agent that contains thrombin and gelatin granules, in brain tumor resections. METHODS: We evaluated the hemostatic effect of FLOSEAL by scoring the intensity of bleeding from 1 (mild) to 4 (life threatening). We assessed the rate of success of hemostasis with 100 patients who underwent intracranial tumor resection. We also investigated the duration of the operation, the amount of intra- and postoperative bleeding, the number of hospital stays, and adverse events in patients who used FLOSEAL compared with those who did not use FLOSEAL. RESULTS: FLOSEAL was applied to a total of 109 bleeding areas in 100 patients. A total of 95 bleeding areas had a score of 1 and 91 (96%) showed successful hemostasis. Thirteen bleeding areas scored 2 and 8 (62%) showed hemostasis with the first application of FLOSEAL. The second application was attempted with five bleeding areas and four showed hemostasis. About 94% (103/109 areas) of bleeding points successfully achieved hemostasis by FLOSEAL. Moreover, FLOSEAL significantly decreased the amount of intraoperative bleeding and postoperative bleeding as assessed with computed tomography on 1 day postoperatively compared with no use of FLOSEAL. There were no adverse events related to FLOSEAL use. CONCLUSION: Our results indicate that FLOSEAL is a reliable, convenient, and safe topical hemostatic agent for intracranial tumor resection.
