RESUMO

The recent study by Kaiwen Wang et al., titled "Early postoperative acetylsalicylic acid administration does not increase the risk of postoperative intracranial bleeding in patients with spontaneous intracerebral hemorrhage," explores the association between postoperative intracranial bleeding (PIB) and various risk factors, including smoking, pre-hemorrhagic antiplatelet therapy, and dyslipidemia. While the study highlights that smoker, particularly women, are at increased risk for subarachnoid hemorrhage and acknowledges the risks of pre-hemorrhagic antiplatelet use, it overlooks the potential risk of PIB associated with early postoperative aspirin administration. This critique underscores the need to approach the study's findings with caution, given the broader context of aspirin's risk profile. Specifically, aspirin has been associated with a 37% higher relative risk of any intracranial hemorrhage, as indicated by other randomized trials. Additionally, the study's implications regarding the benefits of aspirin in stroke prevention must be critically evaluated, as the increased risk of intracranial bleeding may outweigh the potential benefits. This abstract emphasizes the importance of careful consideration of aspirin's adverse effects in the context of postoperative care.

RESUMO

To investigate the safety of pancreatic body suspension (PBS) technique in laparoscopic splenectomy combined with pericardial devascularization for patients. A retrospective study inclusive of 16 patients who underwent laparoscopic splenectomy combined with pericardial devascularization from 2017 to 2022 was performed. A total of 5 patients underwent PBS technique and 11 underwent the traditional technique. There was no significant difference in age, sex, body mass index (BMI), preoperative serum white cell count (WBC), platelets (PLT), hemoglobin (HB), albumin (ALB), prothrombin time (PT), total bilirubin (TBIL), or spleen size between the 2 groups (P > .05). In the PBS group, the operation time was 280 minutes. The estimated intraoperative blood loss (EBL) was 250 mL. The mean postoperative hospitalization length was 11.2 days. There was no conversion to an open procedure or postoperative bleeding. In the traditional method group, the mean operation time was 240.91 minutes. The EBL was 290.91 mL. There were 2 cases of conversion to open, 3 cases of postoperative bleeding, and 1 reoperation. The incidence of postoperative short-term complications (postoperative bleeding, reoperation) was significantly higher in the traditional method group than in the PBS group (36.36% vs 0%, P = .034). PBS technique improved the safety of laparoscopic splenectomy combined with pericardial dissection and is worthy of clinical promotion.

RESUMO

BACKGROUND: This study aimed to evaluate the risk and timing of postoperative bleeding complications following breast-conserving surgery (BCS), with or without axillary surgery, especially in relation to perioperative management of antithrombotic medications. METHODS: Data from all patients who underwent BCS for breast cancer between 2010 and 2022 at a single university hospital were collected. Medical records were reviewed for reoperations, unplanned admissions, and patient characteristics. RESULTS: In total, 4712 breast-conserving surgeries and 3631 axillary surgeries were performed on 3838 patients. The risk of any bleeding complication was 1.1% (40/3571) in breast-conserving surgery, 0.3% (9/2847) in sentinel lymph node biopsy, and 0.5% (4/779) in axillary lymph node dissection. Upon arrival for treatment, 645 (17%) patients were taking antithrombotic medications. The risk of bleeding complications was not elevated in patients whose medication was discontinued at least a day before the surgery (OR 0.84, p = 0.76); but it was almost four-fold (OR 3.61, p = 0.026) in patients whose antithrombotic medication was continued. However, the absolute risk for bleeding complication was low in these patients as well (2.0%, 15/751). The majority of bleeding complications (85%, 47/55) occurred within 24 h after the surgery. CONCLUSION: The risk for bleeding complications was elevated, but still low, after BCS with or without axillary surgery, when antithrombotic medications were continued through the surgical period. Discontinuing antithrombotic medications is not obligatory in these patients.

RESUMO

Reoperation for bleeding (ROB) after emergency coronary artery bypass grafting (eCABG) has been identified as an independent risk factor for mortality. Consecutively, the influence of fluid intake, fluid output, fluid balance, blood loss, and inotropic demand on ROB were analyzed. This retrospective single-center study included 265 patients undergoing eCABG between 2011 and 2020. From 2018, postoperative hemodynamic management was performed with lower volume administration and higher vasoactive support. The primary outcome measure was the incidence of ROB within 48 h according to altered fluid resuscitation strategy. Consecutively, the influence of fluid intake, fluid output, fluid balance, blood loss, and inotropic demand on ROB were analyzed. Incidence of ROB was independent from the volume resuscitation protocol (P = .3). The ROB group had a higher perioperative risk, which was observed in EuroSCORE II. Fluid intake (P = .021), fluid balance (P = .001), and norepinephrine administration (P = .004) were associated with ROB. Fluid output and blood loss were not associated with ROB (P = .22). Post-test probability was low among all variables. Although fluid management might have an impact on specific postoperative complications, different fluid resuscitation protocols did not alter the incidence of ROB after emergency CABG.

RESUMO

The risk factors for immediate post-polypectomy bleeding (IPPB) after cold snare polypectomy (CSP) are not well-known. We sought to define such risk factors and develop a predictive risk-scoring model. This prospective observational study included 161 polyps (4-9 mm in diameter) that were removed via CSP from 118 patients during the period from June to September 2019 in 2 tertiary hospitals. IPPB was defined as post-polypectomy bleeding within 24 hours or grade 3 or 4 intraprocedural bleeding requiring endoscopic hemostasis. IPPB incidences according to grade were 13.0% (21/161) (grade 3) and 0% (grade 4). Univariate analysis showed that the polyp size and morphology, as well as iatrogenic ulcer size and shape, were significantly associated with IPPB. Multivariate analysis showed that polyp size [6-9 mm vs 4-5 mm, odds ratio (OR) 3.72, 95% confidence interval (CI) 1.28-10.79], polyp morphology (polypoid vs non-polypoid, OR: 3.93, 95% CI: 1.22-12.64), and iatrogenic ulcer size (≥10 vs ≤ 9 mm, OR: 3.12, 95% CI: 1.04-9.38) were significantly associated with IPPB. We created a four-marker risk-scoring model to predict IPPB after CSP; we summed the points assigned for the 4 factors. At a cutoff of 2, the sensitivity was 85.7% and the specificity was 65.0%; at a cutoff of 3, the sensitivity was 65% and the specificity was 90.0%. Polyp size and morphology, as well as iatrogenic ulcer size and shape, were associated with IPPB after CSP. The four-marker risk-scoring model appears to effectively predict IPPB after CSP (Clinical Research Information Service: KCT0004375).

RESUMO

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.

RESUMO

BACKGROUND: In the emergency department (ED), there are pre-assembled tonsillar hemorrhage trays for management of post-tonsillectomy hemorrhage and peritonsillar abscess. After use, the tray is sent to the medical device reprocessing (MDR) department for decontamination, sterilization, and re-organization, all at a significant cost to the hospital and environment. OBJECTIVE: The goal of this project was to reduce unnecessary instruments on the tonsil hemorrhage tray by 30% by 1 year and report on the associated cost and carbon dioxide (CO2) emissions savings. METHODS: This quality improvement project was framed according to the Institute for Healthcare Improvement's Model for Improvement. ED and Otolaryngology-Head & Neck Surgery staff and residents were surveyed to determine which instruments on the tonsil hemorrhage trays were used regularly. Based on results, a new tray was developed and compared to the old tray using MDR data and existing CO2 emissions calculations. RESULTS: Tray optimization resulted in a total cost reduction from $1092.63 to $330.21 per tray per year, decreased processing time from 12 to 6-8 minutes per tray, and decreased CO2 emissions from 6.11 to 2.85 kg per year for the old versus new tray, respectively. Overall, the new tray contains half the number of instruments, takes half the time to assemble, produces 50% less CO2 emissions, and will save the hospital approximately $100,000 over 10 years. CONCLUSION: Healthcare costs and environmental sustainability are collective responsibilities. Surgical and procedure tray optimization is a simple, effective, and scalable form of eco-action.

RESUMO

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.

RESUMO

Postpancreatectomy hemorrhage (PPH) is an important risk factor for postoperative complications after laparoscopic pancreaticoduodenectomy (LPD). Recent studies have reported that the use of ligamentum teres hepatis (LTH) in LPD may reduce the risk of PPH. Therefore, this study aims to investigate whether wrapping the hepatic hilar artery with the LTH can reduce PPH after LPD. We reviewed the data of 131 patients who underwent LPD in our team from April 2018 to December 2023. The patients were divided into Groups A (60 patients) and B (71 patients) according to whether the hepatic portal artery was wrapped or not. The perioperative data of the two groups were compared to evaluate the effect of LTH wrapping the hepatic hilar artery on LPD. The platelet count of Group A was (225.25 ± 87.61) × 10^9/L, and that of Group B was (289.38 ± 127.35) × 10^9/L, with a statistically significant difference (p < 0.001). The operation time of group A [300.00 (270.00, 364.00)] minutes was shorter than that of group B [330.00 (300.00, 360.00)] minutes, p = 0.037. In addition, A set of postoperative hospital stay [12.00 (10.00, 15.00)] days shorter than group B [15.00 (12.00, 19.50)] days, p < 0.001. No PPH occurred in Group A, while 8 patients in Group B had PPH (7 cases of gastroduodenal artery hemorrhage and 1 case of proper hepatic artery hemorrhage), p = 0.019. The new technique of wrapping the hepatic hilar artery through the LTH can effectively reduce the occurrence of PPH after LPD.

RESUMO

Fascia iliaca compartment block (FICB) reduces opioid consumption and pain scores after total hip arthroplasty (THA), and has recently been widely applied. We investigated whether FICB could also reduce postoperative bleeding. One hundred and fifteen consecutive patients who underwent elective THA under general anesthesia over 5 months were retrospectively analyzed. They were divided into 2 groups: the FICB group received an epinephrine-mixed FICB procedure and the control group did not receive any block. Using the hematocrit measured at 4 different time points (preoperative and 1, 24, and 48 hours after surgery), the estimated blood loss (EBL) was calculated for 3 different time periods (0-1, 1-24, 24-48 hours after surgery). EBL at 1 to 24 hours (226 vs 398 mL, P = .008) was significantly lower in the FICB group than in the control group. Additionally, the number of packed red cell (PRC) units transfused per patient over 48 hours was 0.38 units in the FICB group, which was significantly lower than the 0.70 units used in the control group (P = .040). Epinephrine-mixed FICB in THA has the potential to reduce postoperative bleeding in the first 24 hours after surgery as well as reduce PRC transfusion requirements.

RESUMO

BACKGROUND: Congenital portosystemic shunts (CPSS) are rare congenital abnormalities causing abnormal blood flow between the portal vein and systemic circulation. This study reports on the peri-operative anticoagulation management of CPSS patients post closure, focusing on the incidence of thrombotic and bleeding complications. METHODS: This is a single-center retrospective analysis of CPSS patients who underwent surgery or endovascular intervention between 2005 and 2021. The protocol included unfractionated heparin (UFH) during and immediately after surgery, followed by either warfarin or low molecular weight heparin (LMWH) postoperatively. Outcomes assessed included postoperative thrombotic and bleeding complications. RESULTS: A total of 44 patients were included. Postoperatively, 89% received treatment-dose UFH, transitioning to warfarin or LMWH at discharge. Thrombotic complications occurred in 16% of patients, predominantly in the superior mesenteric vein. Surgical interventions and continuous infusion of tissue plasminogen activator (tPA) were used for clot resolution. Bleeding complications were observed in 64% of patients, primarily managed with transfusions and temporary UFH interruption. No deaths related to thrombotic, or bleeding events were reported. CONCLUSIONS: Our findings underscore the delicate balance required in anticoagulation management for CPSS patients, revealing an occurrence of both thrombotic and bleeding complications postoperatively. LEVELS OF EVIDENCE: Level II, retrospective study.

RESUMO

Importance: Direct oral anticoagulants (DOACs), comprising apixaban, rivaroxaban, edoxaban, and dabigatran, are commonly used medications to treat patients with atrial fibrillation and venous thromboembolism. Decisions about how to manage DOACs in patients undergoing a surgical or nonsurgical procedure are important to decrease the risks of bleeding and thromboembolism. Observations: For elective surgical or nonsurgical procedures, a standardized approach to perioperative DOAC management involves classifying the risk of procedure-related bleeding as minimal (eg, minor dental or skin procedures), low to moderate (eg, cholecystectomy, inguinal hernia repair), or high risk (eg, major cancer or joint replacement procedures). For patients undergoing minimal bleeding risk procedures, DOACs may be continued, or if there is concern about excessive bleeding, DOACs may be discontinued on the day of the procedure. Patients undergoing a low to moderate bleeding risk procedure should typically discontinue DOACs 1 day before the operation and restart DOACs 1 day after. Patients undergoing a high bleeding risk procedure should stop DOACs 2 days prior to the operation and restart DOACs 2 days after. With this perioperative DOAC management strategy, rates of thromboembolism (0.2%-0.4%) and major bleeding (1%-2%) are low and delays or cancellations of surgical and nonsurgical procedures are infrequent. Patients taking DOACs who need emergent (<6 hours after presentation) or urgent surgical procedures (6-24 hours after presentation) experience bleeding rates up to 23% and thromboembolism as high as 11%. Laboratory testing to measure preoperative DOAC levels may be useful to determine whether patients should receive a DOAC reversal agent (eg, prothrombin complex concentrates, idarucizumab, or andexanet-α) prior to an emergent or urgent procedure. Conclusions and Relevance: When patients who are taking a DOAC require an elective surgical or nonsurgical procedure, standardized management protocols can be applied that do not require testing DOAC levels or heparin bridging. When patients taking a DOAC require an emergent, urgent, or semiurgent surgical procedure, anticoagulant reversal agents may be appropriate when DOAC levels are elevated or not available.

RESUMO

Objective: To evaluate the clinical efficacy of transoral robotic surgery (TORS) with the da Vinci robot system in the treatment of oropharyngeal squamous cell carcinoma (OPSCC). Methods: A mixed cohort study was conducted to collect and analyze the clinical data of OPSCC patients who underwent TORS at the Eye & ENT Hospital, Fudan University between July 2020 and February 2023 (TORS group). OPSCC patients who underwent conventional surgery between January 2016 and September 2020 were included as the control group. The baseline information, incidence of complications and follow-up data were compared between the two groups. Results: A total of 166 patients were included, with 102 cases (81 males and 21 females) in the TORS group [mean age: (59.1±9.8) years] and 64 cases (54 males and 10 females) in the control group [ mean age: (57.6±9.7) years]. Compared with the control group, the TORS group had lower postoperative bleeding rate [2.9% (3/102) vs 10.9% (7/64), P=0.035] and infection rate [1.0% (1/102) vs 18.8% (12/64), P<0.001]. No statistically significant differences were observed in tracheotomy rate [46.1% (47/102) vs 59.4% (38/64), P=0.070] and median length of hospital stay [8 (7, 10) d vs 10 (4, 12) d, P=0.088]. After propensity score matching, compared with the control group, the TORS group had lower postoperative infection rate [0 (0/31) vs 19.4% (6/31), P=0.032] and median length of hospital stay [7 (7, 10) d vs 10 (8, 12) d, P=0.031]. No statistically significant differences were found in postoperative bleeding rate [3.2% (1/31) vs 6.5% (2/31), P=1.000] and tracheotomy rate [22.6% (7/31) vs 45.2% (14/31), P=0.060] between the two groups. Moreover, 1-and 2-year disease-free survival rates were 96.3% and 94.6% in the TORS group, and 90.6% and 84.3% in the control group, respectively (P=0.233). The 1-and 2-year cancer-specific survival rates were both 100% in the TORS group, and 96.9% and 93.8% in the control group, respectively (P=0.539). Conclusion: TORS for OPSCC is associated with high clinical safety and favorable oncological outcomes.

RESUMO

INTRODUCTION: Reduced thrombin generation is an important component of post cardiopulmonary bypass (CPB) coagulopathy. To replenish coagulation factors and enhance thrombin generation in bleeding surgical patients, frozen plasma (FP) and four-factor prothrombin complex concentrate (4F-PCC) are used. However, the efficacy-safety balance of 4F-PCC relative to FP in cardiac surgery is unconfirmed. METHODS AND ANALYSIS: LEX-211 (FARES-II) is an active-control, randomised, phase 3 study comparing two coagulation factor replacement therapies in bleeding adult cardiac surgical patients at 12 hospitals in Canada and the USA. The primary objective is to determine whether 4F-PCC (Octaplex/Balfaxar, Octapharma) is clinically non-inferior to FP for haemostatic effectiveness. Inclusion criteria are any index (elective or non-elective) cardiac surgery employing CPB and coagulation factor replacement with 4F-PCC or FP ordered in the operating room for bleeding management. Patients will be randomised to receive 1500 or 2000 international units of 4F-PCC or 3 or 4 units of FP, depending on body weight. The primary endpoint of haemostatic treatment response is 'effective' if no additional haemostatic intervention is required from 60 min to 24 hours after the first initiation of 4F-PCC or FP; or 'ineffective' if any other haemostatic intervention (including a second dose of study drug) is required. An estimated 410 evaluable patients will be required to demonstrate non-inferiority (one-sided α of 0.025, power ≥90%, non-inferiority margin 0.10). Secondary outcomes include transfusions, bleeding-related clinical endpoints, coagulation parameters and safety. ETHICS AND DISSEMINATION: The trial has been approved by the institutional review boards of all participating centres. Trial completion is anticipated at the end of 2024, and results will be disseminated via publications in peer-reviewed journals and conference presentations in 2025. The results will advance our understanding of coagulation management in bleeding surgical patients, potentially reducing the need for allogeneic blood products and improving outcomes in surgical patients. TRIAL REGISTRATION NUMBER: NCT05523297.

RESUMO

RATIONALE: Postoperative bleeding after lobectomy is relatively rare. By analyzing and discussing the case history and management of hemorrhagic shock caused by chest tube removal after lobectomy, we can achieve the purpose of preventing postoperative bleeding after thoracic surgery and reducing postoperative complications, which can help avoid the risk of second surgery, shorten the patient's hospital stay, reduce the cost of medical care, and improve the patient's quality of life. PATIENT CONCERNS: A case of bleeding from tube removal after lobectomy. The bleeding from chest drain removal on the 3rd day after thoracoscopic lobectomy resulted in hemorrhagic shock, which was stopped by thoracoscopic exploration again under active antishock, and there was no recurrence of bleeding after the operation, and the patient was discharged from the hospital after chest drain removal. DIAGNOSES: Enhanced computed tomography of the chest revealed a space-occupying lesion in the middle lobe of the right lung. INTERVENTIONS: Thoracoscopy was performed again on the condition of active anti-shock. OUTCOMES: On the third day after thoracoscopic lobectomy, the patient underwent removal of the chest drain and subsequently experienced hemorrhagic shock. Given the necessity of maintaining anti-shock measures, the patient was subjected to a second thoracoscopic exploration with the objective of halting the hemorrhage. Following this procedure, the patient did not present with any further episodes of bleeding. Subsequently, a new chest drain was placed, and once the drainage flow had diminished to an acceptable level, the chest drain was removed. The patient subsequently made a full recovery and was discharged from the hospital. LESSONS: Even if the safely inserted drain tube is removed, the thoracic surgeon must be aware of possible vascular bleeding.
