RESUMO
OBJECTIVE: Aim: To improve the management of morbidly obese patients who undergo gastric bypass surgery to reduce the number of postoperative complications, in particular, bleeding. PATIENTS AND METHODS: Materials and Methods: From 2011 to 2022, a total of 348 patients with morbid obesity (MO) underwent laparoscopic gastric bypass treatment at the clinical base of the Department of General Surgery â2 of Bogomolets National Medical University. The retrospective group included 178 patients who received treatment between 2011 and 2019. 170 patients were enrolled in the prospective group for the period from 2019 to 2022. RESULTS: Results: Retrospective group had 8 episodes of postoperative bleeding, representing a rate of 4.49%, prospective group - 3 episodes of postoperative bleeding, representing a rate of 1.76% Four factor characteristics associated with the probability of bleeding were identified: "number of comorbid conditions", "arterial hypertension", "chronic liver diseases" and "chronic obstructive pulmonary disease". CONCLUSION: Conclusions: The factors responsible for the occurrence of postoperative bleeding in morbidly obese patients after laparoscopic gastric bypass surgery were the number of comorbid conditions, the presence of arterial hypertension, the presence of chronic liver diseases, and chronic obstructive pulmonary disease. A new strategy for the management of morbidly obese patients after laparoscopic gastric bypass was developed. This strategy involves changing cassettes to create gastroentero- and enteroenteroanastomoses, reducing the period of use of the nasogastric tube, drains, and urinary catheter from 3-4 days to 1 day, and resuming the drinking regimen 6 hours after extubation.

The complications anticipated in the postoperative period after surgical resection of lateral ventricular neoplasms (LVN) are hemorrhage, hydrocephalus. At the N.N. Burdenko Neurosurgery Center, 48 patients with LVN underwent surgical resection. We focused on the correlation between approaches to the ventricular system on one hand and the extent of resection and incidence of complications on the other based on anatomical and perfusion characteristics estimated via preoperative magnetic resonance imaging (MRI) with arterial spin labeling perfusion. By eliminating the surgical approach as a potential risk factor, we were able to demonstrate the correlation between the frequency of postoperative hemorrhage, the Evans index value, patient's gender, tumor blood flow (nTBF) and the location of the mass in the anterior horn of the lateral ventricle. The risk of hemorrhage depends on the patient's gender, presence of hydrocephalus, location of the mass and tumor blood flow values. The risk increases along with increase in Evance index and nTBF values.

Scoliosis is the most prevalent type of spinal deformity, with a 2-3% prevalence in the general population. Moreover, surgery for scoliotic deformity may result in severe blood loss and, consequently, the need for blood transfusions, thereby increasing surgical morbidity and the rate of complications. Several antifibrinolytic drugs, such as tranexamic acid, have been regarded as safe and effective options for reducing blood loss. Therefore, the present study aimed to analyse the effectiveness of this drug for controlling bleeding when used intraoperatively and in the first 48 h after surgery. A prospective randomized study of a cohort of patients included in a mass event for scoliosis treatment using PSF was performed. Twenty-eight patients were analysed and divided into two groups: 14 patients were selected for intraoperative and postoperative use of tranexamic acid (TXA), and the other 14 were selected only during the intraoperative period. The drainage bleeding rate, length of hospital stay, number of transfused blood units, and rate of adverse clinical effects were compared. All the patients involved had similar numbers of fusion levels addressed and similar scoliosis profiles. The postoperative bleeding rate through the drain did not significantly differ between the two groups (p > 0.05). There was no significant difference in the number of transfused blood units between the groups (p = 0.473); however, in absolute numbers, patients in the control group received more transfusions. The length of hospital stay was fairly similar between the groups, with no statistically significant difference. Furthermore, the groups had similar adverse effects (p = 0.440), with the exception of nausea and vomiting, which were twice as common in the TXA group postoperatively than in the control group. No significant differences were found in the use of TXA during the first 48 postoperative hours or in postoperative outcomes.

Postoperative hemorrhage can severely affect the patients' neurological outcome after awake craniotomy. Higher postoperative blood pressure can increase the risk of postoperative hemorrhage. The aim of this study was to investigate the role of postoperative blood pressure and other common radiological and epidemiological features with the incidence of postoperative hemorrhage. In this retrospective analysis, we included patients who underwent awake surgery at our institution. We assessed the blood pressure both intra- and postoperatively as well as the heart rate for the first 12 h. We compared a cohort with postoperative hemorrhage, who required further treatment (surgical revision or intravenous antihypertensive therapy), with a cohort with no postoperative hemorrhage. We included 48 patients with a median age of 39 years. 9 patients (19%) required further treatment due to postoperative hemorrhage, which was surgery in 2 cases and intensive blood pressure measurements in 7 cases. However, with early treatment, no significant difference in Performance scores at follow-up could be found. Patients with postoperative hemorrhage showed significantly higher postoperative systolic blood pressure during the hours 3-12 (p < 0.05) as well as intraoperatively throughout the procedure (p < 0.05). In ROC and Youden Test, a strong impact of systolic blood pressure over 140mmHg during the early postoperative course could be shown. Postoperative hemorrhage is a rare but possible complication in awake surgery glioma patients. To avoid postoperative hemorrhage, treating physicians should aim strictly on systolic blood pressure of under 140mmHg for the postoperative course.

This study aims to analyze the risk factors associated with delayed postoperative bleeding (DPPB) following colorectal polyp surgery, develop a dynamic nomogram and evaluate the model efficacy, provide a reference for clinicians to identify the patients at high risk of DPPB. Retrospective study was done on patients who underwent endoscopic colorectal polypectomy at the First Hospital of Lanzhou University from January 2020 to March 2023. Differences between the group with and without DPPB were compared, and independent risk factors for DPPB occurrence were identified through univariate analysis and combination LASSO and logistic regression. A dynamic nomogram was constructed based on multiple logistic regression to predict DPPB following colorectal polyp surgery. Model evaluation included receiver operating characteristic (ROC), Calibration curve, Decision curve analysis (DCA). DPPB occurred in 38 of the 1544 patients included. multivariate analysis showed that direct oral anticoagulants (DOACs), polyp location in the right hemi colon, polyp diameter, drink, and prophylactic hemoclips were the independent risk factors for DPPB and dynamic nomogram were established. Model validation indicated area under the ROC curve values of 0.936, 0.796, and 0.865 for the training set, validation set, and full set, respectively. The calibration curve demonstrated a strong alignment between the predictions of the column-line diagram model and actual observations. The decision curve analysis (DCA) displayed a significant net clinical benefit across the threshold probability range of 0-100%. The dynamic nomogram aids clinicians in identifying high-risk patients, enabling personalized diagnosis and treatment.

OBJECTIVES: To evaluate the association between guideline-conforming as compared to shorter than recommended withdrawal period of P2Y12 receptor inhibitors prior to isolated on-pump coronary artery bypass grafting (CABG) and the incidence of severe bleeding and ischaemic events. Randomized controlled trials are lacking in this field. METHODS: We searched PUBMED, Embase and other suitable databases for studies including patients on P2Y12 receptor inhibitors undergoing isolated CABG and reporting bleeding and postoperative ischaemic events from 2013 to March 2024. The primary outcome was incidence of Bleeding Academic Research Consortium type 4 (BARC-4) bleeding defined as any of the following: perioperative intracranial bleeding, reoperation for bleeding, transfusion of ≥5 units of red blood cells, chest tube output of ≥2 l. The secondary outcome was postoperative ischaemic events according to the Academic Research Consortium 2 Consensus Document. Patient-level data provided by each observational trial were synthesized into a single dataset and analysed using a 2-stage IPD-MA. RESULTS: Individual data of 4837 patients from 7 observational studies were synthesized. BARC-4 bleeding, 30-day mortality and postoperative ischaemic events occurred in 20%, 2.6% and 5.2% of patients. After adjusting for EuroSCORE II and cardiopulmonary bypass time, guideline-conforming withdrawal was associated with decreased BARC-4 bleeding risk in patients on clopidogrel [adjusted odds ratio (OR) 0.48; 95% confidence intervals (CI) 0.28-0.81; P = 0.006] and a trend towards decreased risk in patients on ticagrelor (adjusted OR 0.48; 95% CI 0.22-1.05; P = 0.067). Guideline-conforming withdrawal was not significantly associated with 30-day mortality risk (clopidogrel: adjusted OR 0.70; 95% CI 0.30-1.61; ticagrelor: adjusted OR 0.89; 95% CI 0.37-2.18) but with decreased risk of postoperative ischaemic events in patients on clopidogrel (clopidogrel: adjusted OR 0.50; 95% CI 0.30-0.82; ticagrelor: adjusted OR 0.78; 95% CI 0.45-1.37). BARC-4 bleeding was associated with 30-day mortality risk (adjusted OR 4.76; 95% CI 2.67-8.47; P < 0.001). CONCLUSIONS: Guideline-conforming preoperative withdrawal of ticagrelor and clopidogrel was associated with a 50% reduced BARC-4 bleeding risk when corrected for EuroSCORE II and cardiopulmonary bypass time but was not associated with increased risk of 30-day mortality or postoperative ischaemic events.

BACKGROUND: Tranexamic acid (TXA) is a widely employed intervention in orthopedic surgeries to minimize blood loss and the need for postoperative transfusions. This study focuses on assessing the efficacy and safety of TXA specifically in undernourished older adults undergoing hip fracture procedures. METHODS: A total of 216 patients were classified into two groups based on the Geriatric Nutritional Risk Index: undernourished and normal. In total, 82 patients received intravenous TXA at a dosage of 15 mg/kg before incision, with an additional 1 g administered intravenously over a 3-hour period postoperatively. Postoperative hemoglobin (Hb) drop, blood transfusion rate, and the incidence of deep venous thrombosis (DVT) were assessed in each group according to the presence or absence of TXA. Additionally, demographic factors including age, sex, body mass index, and serum albumin were investigated. RESULTS: 51.9% patients were identified as undernourished, experiencing progressive anemia (Hb: 10.9 ± 1.5 g/dL) and hypoalbuminemia (serum albumin: 31.9 ± 8 g/L). In comparison with the normal group, undernourished individuals were more likely to sustain femoral neck fractures (undernutrition vs. normal: 56.2 vs. 42.3%) and less likely to incur trochanteric fractures (undernutrition vs. normal: 43.8 vs. 57.7%) (P = 0.043). TXA administration significantly reduced the transfusion rate (P = 0.014) and Hb drop (P = 0.001) in the normal nutritional group, while its impact on the undernourished group remained less pronounced. There was no significant association between TXA administration and the rate of DVT complications, irrespective of the nutritional status. CONCLUSIONS: Undernutrition not only diminishes muscle strength and gait function, leading to various types of hip fractures, but it may also hinder the efficacy of TXA in reducing blood transfusion rates and blood loss.

OBJECTIVE: To better understand the incidence and timing of thrombotic and hemorrhagic complications in anticoagulated patients undergoing elective surgery. METHODS: Using institutional American College of Surgeons National Surgical Quality Improvement Program data, we identified patients receiving preoperative anticoagulation undergoing elective surgery between 2011 and 2021. Medical records review supplemented National Surgical Quality Improvement Program data to detail complication and anticoagulation type and timing. Outcomes for postoperative hemorrhage, acute venous thromboembolism (VTE), and cerebrovascular accident (CVA) were collected. RESULTS: A total of 1442 patients met inclusion criteria, and 84 patients (5.8%) experienced 1 or more complications. There were 4 CVA (0.3%), 16 VTE (1.1%), and 68 bleeding (4.7%) events postoperatively. Three patients (75%) with CVA, 10 patients (62.5%) with VTE, and 18 patients (26.5%) with postoperative bleeding had resumed therapeutic anticoagulation before the complication. In terms of long-term sequelae in the CVA cohort, there was 1 mortality (25%), and an additional patient (25%) continues to experience long-term physical and mild cognitive impairments. Patients who experienced postoperative VTE required only anticoagulation adjustments. In patients who experienced bleeding complications, 6 (8.8%) required intensive care unit admissions, and there was 1 mortality (1.5%). CONCLUSION: Despite the increased use of anticoagulation over time, balancing postoperative bleeding and thrombotic risks remains challenging. Bleeding complications were most common in preoperatively anticoagulated patients undergoing elective surgery. Earlier postoperative resumption of anticoagulation is unlikely to prevent thrombotic events as 65% of patients had already resumed therapeutic anticoagulation.

Because of its superior safety profile and improved outcomes, trans-radial percutaneous coronary intervention (TRI) has become the preferred access in percutaneous coronary intervention (PCI) of native coronary disease. This study investigated the impact of TRI on in-hospital outcomes after PCI for coronary artery bypass graft vessels (GV-PCI). We analyzed patients who underwent GV-PCI in 2019-2022 from the Japanese nationwide registry. Patients were categorized into the TRI and trans-femoral PCI (TFI) groups. We assessed the association between TRI and in-hospital outcomes. The primary outcome was a composite of in-hospital death and major bleeding. In this study, 2,295 patients were analyzed.. The primary outcomes occurred in 29 patients (1.3%), including 17 deaths (0.7%). Major bleeding occurred in 12 patients (0.5%), and access site bleeding in 7 patients (0.3%). The TRI group (n = 1,521) showed lower crude rates of the primary outcome (0.9% vs 1.9%, p = 0.039), major bleeding (0.3% vs 1.0%, p = 0.027), and access site bleeding (0.1% vs 0.6%, p = 0.047) compared with the TFI group (n = 774). Univariable logistic regression demonstrated a significant association of TRI with reduced primary outcome (odd ratio [OR] 0.47, 95% confidence interval [CI] 0.22 to 0.98), major bleeding (OR 0.25, 95% CI 0.07 to 0.80), and access site bleeding (OR 0.20, 95% CI 0.03 to 0.94). In the multivariable analysis, TRI was still significantly associated with a decrease in major bleeding events (OR 0.29, 95% CI 0.07 to 0.93). In conclusion, the use of TRI was associated with a reduction in bleeding events when referenced to TFI in the context of GV-PCI.

INTRODUCTION: Sleeve gastrectomy (SG) is currently the most frequently performed procedure for obesity worldwide. Staple line reinforcement (SLR) has been suggested as a strategy to reduce the risk of staple line leak or bleeding; however, its use for SG in the United Kingdom (UK) is unknown. This study examined the effect of SLR on the development of postoperative complications from SG using a large national dataset from the UK. METHODS: Patients undergoing either primary or revision SG over 10 years from Jan 2012 to Dec 2021 were identified by the National Bariatric Surgery Registry. Comparative and logistic regression analyses were undertaken to determine the effect of SLR on staple line leak and bleeding. RESULTS: During this time, 14,231 patients underwent SG for whom there were complete data. Of these, 76.5% were female and the median age was 46 years (IQR: 36-53). The rate of surgical complications was 2.3% (n = 219/14,231). The incidence of bleeding was 1.3% (n = 179/14,231) and leak was 1.0% (n = 140/14,231). Over time, the use of SLR of any variety declined significantly from 99.7% in 2012 to 57.3% in 2021 (p < 0.001). Multivariable (adjusted) regression analysis demonstrated that neither the use of nor the type of reinforcement had any effect on the rate of bleeding or leaking. CONCLUSION: SLR for SG has declined in the UK since 2012. There were no differences in staple line leak or bleed with or without reinforcement.

Removal of third molars in healthy patients is considered a procedure with a low risk of bleeding. However, exactly how low the incidence of postoperative bleeding is remains unclear due to the heterogeneity of available studies. To determine the exact postoperative risk of bleeding after the removal of third molars in healthy patients, a prospective observational multicentre study was conducted. A total of 1,035 patients with complete follow-up was included. Of these, 329 patients reported subsequent bleeding, but did not consult their attending physician. A total of 15 patients visited the hospital, 8 of whom required minimally invasive (re)treatment. No hospitalizations were necessary. There was a large difference between the incidence of postoperative bleeding reported by patients and postoperative bleeding requiring clinical examination and/or treatment. To reduce this difference in future, patients should be given detailed information about what degree of postoperative bleeding is considered normal after removal of a third molar.

OBJECTIVES: To estimate the incidence of post tonsillectomy bleeding and to identify its predisposing factors among the pediatric population. METHODS: A retrospective cohort study included 1280 pediatric patients (18 years or younger) who underwent tonsillectomy at King Abdullah Specialized Children Hospital, Riyadh, Saudi Arabia between 2019 and 2020. The study sample was divided into 2 groups based on the development of postoperative bleeding and were compared using Chi-square test and independent t-test. Significant variables (p-value ≤0.05) were included in the logistic regression model to determine the predictors of bleeding following tonsillectomy. RESULTS: The bleeding rate following tonsillectomy was 3.4% in 43 (95% confidence interval [CI] 2.4-4.5) patients. In the multivariable logistic regression model, the significant predictors of post tonsillectomy bleeding were age ≥12 years (odds ratio [OR]: 2.685, p=0.027), decreased postoperative oral intake (OR: 4.244, p=0.042), and single use of postoperative analgesia (OR: 53.124, p<0.001). Out of the 43 patients, 39 (90.7%) patients experienced secondary bleeding, and more than half of the patients who developed bleeding required surgical intervention 27 (62.8%). CONCLUSION: Tonsillectomy is a safe and common surgical procedure but carries risks for postoperative bleeding. Age ≥12 years, poor postoperative oral intake, and the use of a single postoperative analgesic increase the risk of bleeding. We encourage healthcare providers to ascertain early resumption of oral intake and ensure effective pain management. We recommend a dual alternating analgesic regimen with weight-based dosing for optimal pain control. Furthermore, educating caregivers about the importance of adequate oral intake following tonsillectomy may improve patient outcomes.

BACKGROUND: Delayed bleeding (DB) is a serious complication after cold snare polypectomy (CSP) for polyps in the colon. The present study aimed to investigate the incidence and risk factors of DB after CSP and to develop a risk-scoring model for predicting DB. METHODS: A retrospective study was conducted in four Chinese medical institutions. 10650 patients underwent CSP from June 2019 to May 2023. The study analyzed the rate of DB and extracted the general clinical information and polyp-related information of patients with postoperative DB. As a control, non-DB patients who received CSP at the same 4 hospitals were analyzed. A multivariate Cox regression analysis was performed to develop the prediction model. The model was further validated using a Kaplan-Meier log-rank analysis, receiver operating characteristic curve (ROC) plot and risk plot. RESULTS: In our study, we found a 0.24% rate of DB and the risk factors were history of hypertension, hyperlipidemia, antithrombotics use, antiplatelet use, anticoagulant use, abdominal operation, sigmoid colon lesion, hematoma, cold snare defect protrusion, polyp size, wound size, the grade of wound bleeding, and morphology of Ip. These factors were incorporated into the prediction model for DB after CSP. For 1, 3, and 5 days of bleeding, the AUC of the ROC curve was 0.912, 0.939, and 0.923, respectively. The Kaplan-Meier analysis indicated that the high-risk group had a significantly higher risk of DB than the low-risk group. CONCLUSIONS: This study screened the risk factors and established a prediction model of DB after CSP. The results may help preventing and reducing the DB rate after CSP of colorectal polyps.

BACKGROUND: The efficacy of postoperative tranexamic acid (TXA) administration in mitigating bleeding after primary laparoscopic Roux-en-Y gastric bypass (RYGB), a prevalent complication associated with significant morbidities and mortality, and the use of sequential laboratory parameter changes in bleeding screening and TXA impact tracking were investigated. METHODS: This retrospective analysis included RYGB patients (aged 18-65 years, with a body mass index of 35-50 kg/m2) over 5 years who were categorized into three groups by evolving treatment regimens: Group A (n = 42) received standard pre- and postoperative enoxaparin (30 mg) every 12 h; Group B (n = 160) received enoxaparin and postoperative TXA (250 mg every 6 h); and Group C (n = 73) received TXA alone. Postoperative bleeding-related adverse events, vital signs, and laboratory changes were compared. RESULTS: Postoperative hemorrhage occurred in 3.6% (10/275) of patients, with no significant intergroup differences. Patients who experienced bleeding had greater decreases in hemoglobin (∆Hb) (2.1 vs. 1.4; p = 0.003), greater ∆Hb > 2 (50% vs. 15%; p = 0.013), and greater use of staples than did those who did not experience bleeding (8 vs. 7; p = 0.001). The ∆Hb values were lower in Groups B (1.4) and C (1.3) than in Group A (1.7, p = 0.011). No significant difference was noted between Groups C and B. CONCLUSION: This study emphasizes the potential of TXA to mitigate postoperative bleeding after RYGB, with no added benefit from excluding enoxaparin. Monitoring patients with a ∆Hb > 2 mg/dl and increased stapler usage is crucial. Further research is needed to validate routine TXA use across different procedures.

BACKGROUND: Lung transplantation (LT) represents a high-risk procedure for end-stage lung diseases. This study describes the outcomes of patients undergoing LT that require massive transfusions as defined by the universal definition of perioperative bleeding (UDPB). METHODS: Adult patients who underwent bilateral LT at a single academic center were surveyed retrospectively. Patients were grouped by insignificant, mild, or moderate perioperative bleeding (insignificant-to-moderate bleeders) and severe or massive perioperative bleeding (severe-to-massive bleeders) based on the UDPB classification. Outcomes included 1-year survival and primary graft dysfunction (PGD) of grade 3 at 72 h postoperatively. Multivariable models were adjusted for recipient age, sex, body mass index (BMI), Lung allocation score (LAS), preoperative hemoglobin (Hb), preoperative extracorporeal membrane oxygenation (ECMO) status, transplant number, and donor status. An additional multivariable model was created to find preoperative and intraoperative predictors of severe-to-massive bleeding. A p-value less than 0.05 was selected for significance. RESULTS: A total of 528 patients were included, with 357 insignificant-to-moderate bleeders and 171 severe-to-massive bleeders. Postoperatively, severe-to-massive bleeders had higher rates of PGD grade 3 at 72 h, longer hospital stays, higher mortality rates at 30 days and one year, and were less likely to achieve textbook outcomes for LT. They also required postoperative ECMO, reintubation for over 48 h, tracheostomy, reintervention, and dialysis at higher rates. In the multivariate analysis, severe-to-massive bleeding was significantly associated with adverse outcomes after adjusting for recipient and donor factors, with an odds ratio of 7.73 (95% CI: 4.27-14.4, p < 0.001) for PGD3 at 72 h, 4.30 (95% CI: 2.30-8.12, p < 0.001) for 1-year mortality, and 1.75 (95% CI: 1.52-2.01, p < 0.001) for longer hospital stays. Additionally, severe-to-massive bleeders were less likely to achieve textbook outcomes, with an odds ratio of 0.07 (95% CI: 0.02-0.16, p < 0.001). Preoperative and intraoperative predictors of severe/massive bleeding were identified, with White patients having lower odds compared to Black patients (OR: 041, 95% CI: 0.22-0.80, p = 0.008). Each 1-unit increase in BMI decreased the odds of bleeding (OR: 0.89, 95% CI: 0.83-0.95, p < 0.001), while each 1-unit increase in MPAP increased the odds of bleeding (OR: 1.04, 95% CI: 1.02-1.06, p < 0.001). First-time transplant recipients had lower risk (OR: 0.16, 95% CI: 0.06-0.36, p < 0.001), whereas those with DCD donors had a higher risk of severe-to-massive bleeding (OR: 3.09, 95% CI: 1.63-5.87, p = 0.001). CONCLUSION: These results suggest that patients at high risk of massive bleeding require higher utilization of hospital resources. Understanding their outcomes is important, as it may inform future decisions to transplant comparable patients.

BACKGROUND: Various scoring systems have been developed to assess the risk of bleeding in medical settings. HAS-BLED and HEMORR2HAGES risk scores are commonly used to estimate bleeding risk in patients receiving anticoagulation for atrial fibrillation, but data on their predictive value in patients undergoing percutaneous coronary intervention (PCI) are limited. METHODS: This study evaluated and compared the predictive abilities of the HAS-BLED and HEMORR2HAGES bleeding risk scores in all-comer patients undergoing PCI. The PARIS score, specifically designed for patients undergoing PCI, was used as a comparator. The scores were calculated at baseline and compared with the occurrence of events during a 2-year clinical follow-up period. Between 2015 and 2017, all consecutive patients undergoing PCI we re prospectively enrolled and divided into risk tertiles based on bleeding risk scores. The primary end points were hierarchical major bleeding events, defined by Bleeding Academic Research Consortium types 3 through 5, and patient-oriented composite end points according to Bleeding Academic Research Consortium classification, which were assessed during the 2-year follow-up period. RESULTS: A total of 1,080 patients completed the follow-up period. Two years after index, 189 patients (17.5%) had experienced any bleeding, with 48 events (4.4%) classified as Bleeding Academic Research Consortium types 3 to 5. All bleeding risk scores showed statistically significant predictive ability for bleeding events. The HEMORR2HAGES score (C statistic, 0.73) was more effective than the HAS-BLED score (C statistic, 0.66; P = .07) and the PARIS score (C statistic, 0.66; P = .06) in predicting risk of major bleeding. Patients in high-risk bleeding groups also experienced a higher incidence of patient-oriented composite end points. CONCLUSIONS: The HEMORR2HAGES, HAS-BLED, and PARIS risk scores exhibited good predictive abilities for bleeding events following PCI. Patients at high risk of bleeding also demonstrated increased ischemic risk and higher mortality during the 2-year follow-up period.

Administration of acetylsalicylic acid (ASA) at early stage after surgery for spontaneous intracerebral hemorrhage (SICH) may increase the risk of postoperative intracranial bleeding (PIB), because of potential inhibition of platelet function. This study aimed to investigate whether early ASA administration after surgery was related to increased risk of PIB. This retrospective study enrolled SICH patients receiving surgery from September 2019 to December 2022 in seven medical institution. Based on postoperative ASA administration, patients who continuously received ASA more than three days within seven days post-surgery were identified as ASA users, otherwise as non-ASA users. The primary outcome was symptomatic PIB events within seven days after surgery. Incidence of PIB was compared between ASA users and non-ASA users using survival analysis. This study included 744 appropriate patients from 794 SICH patients. PIB occurred in 42 patients. Survival analysis showed no statistical difference between ASA users and non-ASA users in incidence of PIB (P = 0.900). Multivariate Cox analysis demonstrated current smoker (hazard ratio [HR], 2.50, 95%CI, 1.33-4.71, P = 0.005), dyslipidemia (HR = 3.03; 95%CI, 1.31-6.99; P = 0.010) and pre-hemorrhagic antiplatelet therapy (HR = 3.05; 95% CI, 1.64-5.68; P < 0.001) were associated with PIB. Subgroup analysis manifested no significant difference in incidence of PIB between ASA users and non-ASA users after controlling the effect from factors of PIB (i.e., sex, age, current smoker, regular drinker, dyslipidemia, pre-hemorrhagic antiplatelet therapy and hematoma location). This study revealed that early ASA administration to SICH patients after surgery was not related to increased risk of PIB.

BACKGROUND: Intravenous tranexamic acid (TA) has proven efficacy in reducing blood loss and incidence of transfusion of blood products in elective total joint arthroplasty. However, evidence of efficacy in the setting of intracapsular hip fractures needing hip hemiarthroplasty (HA) or total hip arthroplasty (THA) are scarce. This study aimed to assess post-operative transfusion incidence in this clinical setting. METHODS: Over a five-year period 250 patients with intracapsular neck of femur fractures requiring arthroplasty were randomised to two groups. The treatment group received three-dose intravenous TA protocol and the control group received usual treatment without administration of TA. Blood loss was estimated from the change in Hb levels on day 1, 3 and 5 after surgery compared to preoperative levels. Transfusions of blood products were recorded when they were triggered by an a priori protocol. Post-operative complications were recorded during patient hospital admission. RESULTS: The intervention group showed significantly lower transfusion incidence of packed red blood cells (PRBC) (6 vs. 15, p = 0.04, OR = 0.37, 95%CI OR = 0.14 to 0.99) and in the group of patients who received a blood transfusion, a trend was observed for patients who received TA to have lesser number of units of PRBC (mean = 1.3 vs. 1.6, p = 0.51). A significant difference was noted in post-operative Hb levels of day 1,3 and 5. Backward stepwise multivariable regression analysis showed the use of TA was the most significant factor for reduction in postoperative blood transfusion (p = 0.047, OR = 0.37, 95% CI OR = 0.14 to 0.99). Assessment of the strength of the correlation showed modest correlation (Pearson correlation - 0.13 p = 0.04, 95% CI correlation= -0.25 to -0.01). There was no increase in adverse events in patients who received TA. CONCLUSION: The use of TA in setting of intracapsular hip fractures requiring arthroplasty reduces blood loss, the need for transfusion of blood products and may reduce surgical site complications without increasing the risk of VTE.

INTRODUCTION: Patients who undergo surgery for breast cancer are at risk for venous thromboembolism (VTE) and bleeding, which can lead to significant consequences on outcomes. This study examined factors related to VTE and bleeding risk in breast cancer surgery, with and without reconstruction. We also investigated the relationship between operative time and resident involvement on bleeding and VTE risk. METHODS: Using the ACS-NSQIP database, patients who underwent mastectomy, implant, pedicled, or free flap reconstruction from 2005 to 2021 were identified. Resident involvement was available from 2007 to 2010. We fitted two logistic regressions to model the log odds of bleeding occurrence and VTE as linear functions of procedure type, controlling for age, body mass index, and comorbidities. RESULTS: Implant reconstruction had significantly reduced 30-d incidence of bleeding, compared to those who underwent transverse rectus abdominus muscle flap (P < 0.001). Free flap was associated with a significant increase in bleeding but not VTE risk (P < 0.001; P = 0.132). Increase in operative time significantly increased the risk of bleeding and VTE (P < 0.001). For surgeries with resident involvement coded, there was no significantly increased risk of bleeding or VTE (P = 0.600; P = 0.766). CONCLUSIONS: Implant reconstruction remains the procedure with the lowest risk of both bleeding and VTE. Free flap reconstruction did not show a significantly increased risk of VTE, potentially expanding reconstruction options for patients previously excluded from autologous reconstruction. Surgeons should be mindful of operative time, with re-evaluation of risk factors with each additional hour of surgery, irrespective of reconstruction type. Resident involvement in surgeries should continue to be encouraged by faculty.

BACKGROUND: Severe bleeding remains a significant concern in laparoscopic resection for hepatic hemangioma. It is rarely reported that how the degree of major vessels involvement impacts on severe bleeding. The present study primarily aimed to analyze the impacts of the number of involved major vessels (NIMV) during laparoscopic surgery for hepatic hemangioma and evaluate the risk factors associated with increased bleeding. METHODS: A database search was carried out for consecutive patients who underwent laparoscopic resection for liver hemangiomas at our department from January 2018 to December 2023. The collected data included demographics, characteristics of the hemangiomas, laboratory data, operation method, surgical and postoperative variables. RESULTS: A total of 72 patients were enrolled in the study. 42 patients were categorized into the group with NIMV < 2, while 30 patients were divided into the group with NIMV ≥ 2. The group with NIMV ≥ 2 demonstrated a significant correlation with special segments, involved multiple segments and diameter of the hemangiomas (P < 0.01). And the perioperative variables including the extent of resection, operative time, blood loss, Pringle maneuver times, postoperative stay, drainage tube duration, and postoperative liver function (ALT, AST) also showed significant differences between the two groups (P < 0.05). Notably, NIMV ≥ 2 was identified as the most important independent risk factor for intraoperative blood loss ≥ 500 ml in laparoscopic surgery for hepatic hemangioma (P = 0.011). For NIMV ≥ 2, the independent risk factor was special segments in multivariate analysis (P = 0.000). CONCLUSION: The involvement of multiple major vessels (NIMV ≥ 2) was significantly associated with special segments, resulting in increased intraoperative blood loss, operation difficulty, and delayed postoperative recovery. Moreover, it was identified as the single independent risk factor with a considerable risk for increased blood loss during laparoscopic resection for hepatic hemangioma.
