Urology Aug 2019To describe contemporary management and outcomes of patients experiencing postoperative hemorrhage after minimally invasive radical prostatectomy.
OBJECTIVE
To describe contemporary management and outcomes of patients experiencing postoperative hemorrhage after minimally invasive radical prostatectomy.
MATERIALS AND METHODS
We retrospectively analyzed data from patients who underwent minimally invasive radical prostatectomy at our institution between January 2010 and January 2017. Clinically significant hemorrhage was defined as a decrease in hemoglobin of ≥30% or 4 g/dL from preoperative to 4 or 14 hours postoperative measurement, receiving a blood transfusion within 30 days, or undergoing a secondary procedure to control bleeding. Patients were analyzed in 3 groups: (1) serially monitored only, (2) received a blood transfusion, and (3) underwent a secondary procedure. Outcomes included imaging studies performed, length of stay, emergency room visits, hospital readmissions, complication rates, and functional outcomes.
RESULTS
Of 3749 men, 4% (151/3749) had clinically significant hemorrhage, 1.6% (60/3749) received a transfusion; 0.32% (12/3749) underwent a secondary procedure to control bleeding. In a 30-day composite outcome, increased healthcare utilization (emergency room visit, readmission, or Grade ≥3 complications), was seen in 25% of the serial monitoring group, 65% of the transfusion group, and 100% in the secondary procedure group. This rate in 3598 men without hemorrhage was 12.5%. One-year erectile function was poorest in men who underwent a secondary procedure. Urinary functional outcomes were similar in the 3 groups.
CONCLUSION
Most patients experiencing clinically significant hemorrhage will stabilize without transfusion, and a very small fraction require secondary intervention. Patients experiencing milder bleeding events utilized additional healthcare resources at approximately twice the rate of those who did not, warranting appropriate counseling and postoperative monitoring.

BACKGROUND
Ruptured aneurysm is a serious complication of distal pancreatectomy (DP) or pancreatoduodenectomy (PD) that can be life-threatening if not treated promptly. This study aimed to examine the efficacy of a Viabahn stent graft for stopping bleeding after pancreatectomy.
METHODS
Between April 2016 and June 2022, we performed 245 pancreatectomies in our institution. Six patients experienced postoperative bleeding and underwent endovascular treatment.
RESULTS
All six cases of bleeding occurred post-PD (3.7%). The bleeding was from gastroduodenal artery (GDA) pseudoaneurysms in three patients, and Viabahn stent grafts were inserted. All three patients did not show liver function abnormalities or hepatic blood flow disorders. One patient with a Viabahn stent graft experienced rebleeding, which required further management to obtain hemostasis. Of the six cases in which there was hemorrhage, one case of bleeding from the native hepatic artery could not be managed.
CONCLUSIONS
Using the Viabahn stent graft is an effective treatment option for postoperative bleeding from GDA pseudoaneurysms following PD. In most cases, using this device resulted in successful hemostasis, without observed abnormalities in hepatic function or blood flow.

JAMA Otolaryngology-- Head & Neck... Jul 2022Postthyroidectomy hemorrhage is a potentially life-threatening complication with no reliable noninvasive method of early detection.
IMPORTANCE
Postthyroidectomy hemorrhage is a potentially life-threatening complication with no reliable noninvasive method of early detection.
OBJECTIVE
To evaluate the diagnostic accuracy of neck circumference measurement for early detection of postoperative hemorrhage after thyroidectomy.
DESIGN, SETTING, AND PARTICIPANTS
This diagnostic accuracy study at an academic teaching hospital used a prospective cohort of patients undergoing thyroid surgery from November 1, 2015, to January 31, 2018 (group 1), and a retrospective cohort of patients undergoing the same surgery from January 1, 2020, to September 30, 2021 (group 2). We performed repeated perioperative neck circumference measurements to evaluate the association of increased neck circumference with postthyroidectomy hemorrhage among patients at risk for hemorrhage.
MAIN OUTCOMES AND MEASURES
The primary end point was the diagnostic value of neck circumference measurement for detection of postthyroidectomy hemorrhage. Additionally, data on demographic information and risk factors for postthyroidectomy hemorrhage were examined. Data analyses were performed from November 1, 2021, to January 5, 2022.
RESULTS
The prospective cohort (group 1) comprised 60 patients (45 [75%] women) with a mean (SD) age of 52.2 (13.5) years; those who experienced a postthyroidectomy hemorrhage had a mean (SD) age of 57.4 (9.0) years. The retrospective cohort (group 2) comprised 353 patients (258 [73%] women) with a mean (SD) age of 55.3 (14.1) years; patients who experienced a postthyroidectomy hemorrhage had a mean (SD) age of 62.2 (10.0) years. In group 1, postoperative neck circumference increased by a median (range) of 5.0 (4.0 to 7.0) cm in patients with hemorrhage, and only 1.0 (-2.5 to 4.0) cm in patients with no postoperative bleeding (difference in the medians, 4.0 cm [95% CI, 3.0 to 5.5 cm]; effect size, 3.74 [95% CI, 2.6 to 4.9]). Defining a 7% or greater increase in neck circumference as the cutoff value for detecting postthyroidectomy hemorrhage showed a diagnostic sensitivity and specificity of 1.0 (95% CI, 0.48 to 1.0) and 0.86 (95% CI, 0.71 to 0.92), respectively. The retrospective validation also showed a difference in median (range) increase of postoperative neck circumference between patients with hemorrhage and those without-3.0 (0 to 6.0) cm vs 0.0 (-6.0 to 5.0) cm (difference in medians, 3.8 cm [95% CI, 3.0 to 4.9]; effect size, 1.63 [95% CI, 0.96 to 2.3]). Considering 12 false-positive and 332 correct-negative results, the diagnostic tool showed a sensitivity of 0.89 (95% CI, 0.51 to 0.99) and a specificity of 0.97 (95% CI, 0.94 to 0.98).
CONCLUSIONS AND RELEVANCE
The findings of this diagnostic accuracy study suggest that neck circumference measurement is a feasible and easy-to-use diagnostic tool for routine clinical care to detect postthyroidectomy hemorrhage. A 7% or greater increase over the postoperative baseline neck circumference seems to be a reliable threshold for detecting postthyroidectomy hemorrhage. Neck circumference measurement should be used in combination with surveillance of clinical signs and symptoms.

Excessive bleeding is an important cause of morbidity and mortality after cardiac surgery. Bleeding after cardiac surgery is multifactorial. Adherence to the proverbial 6 Ps remains the cornerstone of any strategy for management of postoperative bleeding after cardiac surgery. Recent years have seen a surge in the number of patients who have been prescribed novel oral anticoagulants (NOACs) for the prevention and treatment of thromboembolic events. This phenomenon has significant repercussions particularly for patients presenting for emergency cardiac surgery. The published evidence guiding management of such patients is limited and in the form of expert consensus. Plasma levels of NOAC >30 ng/ml necessitate specific therapeutic interventions to tackle excessive bleeding attributed to NOAC intake. Current recommendation is to consider using specific reversal agent if available. Otherwise, use of prothrombin complex concentrates is recommended.

BACKGROUND
Differences in clinical outcomes following a temporary interruption of warfarin or a direct oral anticoagulant (DOAC) for a surgical procedure are not well described. Differences in patient characteristics from practice-based cohorts have not typically been accounted for in prior analyses.
AIM
To describe risk-adjusted differences in postoperative outcomes following an interruption of warfarin vs DOACs.
METHODS
Patients receiving care at six anticoagulation clinics participating in the Michigan Anticoagulation Quality Improvement Initiative were included if they had at least one oral anticoagulant interruption for a procedure. Inverse probability of treatment weighting (IPTW) was used to balance baseline differences between the warfarin cohort and DOAC cohort. Bleeding and thromboembolic events within 30 days following the procedure were compared between the IPTW cohorts using the Poisson distribution test.
RESULTS
A total of 525 DOAC patients were matched with 1323 warfarin patients, of which 923 were nonbridged warfarin patients and 400 were bridged warfarin patients. The occurrence of postoperative minor bleeding (10.8% vs. 4.7%, p < .001), major bleeding (2.9% vs. 1.1%, p = .01) and clinically relevant nonmajor bleeding (CRNMB) (6.5% vs. 3.0%, p = .002) was greater in the DOAC cohort compared with the nonbridged warfarin cohort. The rates of postoperative bleeding outcomes were similar between the DOAC and the bridged warfarin cohorts.
CONCLUSION
Perioperative interruption of DOACs, compared with warfarin without bridging, is associated with a higher incidence of 30-day minor bleeds, major bleeds, and CRNMBs. Further research investigating the perioperative outcomes of these two classes of anticoagulants is warranted.

BACKGROUND
Median sternotomy is the most performed procedure in cardiac surgery; however, sternal displacement and bleeding remains a problem. This study aimed to investigate whether sternal reconstruction using a sandwiched three-piece bioresorbable mesh plate can prevent postoperative sternal displacement and bleeding more than a bioresorbable pin.
METHODS
Patients (n = 218) who underwent median sternotomy were classified according to whether a sandwiched three-piece bioresorbable mesh plate and wire cerclage (group M, n = 109) or a bioresorbable pin and wire cerclage (group P, n = 109) were used during sternal reconstruction. The causes of postoperative sternal displacement and bleeding with computed tomography data were analyzed and compared between the groups.
RESULTS
The preoperative patient characteristics did not significantly differ between the groups. However, the evaluation of sternal and substernal hematoma on postoperative day 5 using computed tomography showed sternal displacement in 4 (4%) and 22 (20%) patients, and substernal hematoma in 17 (16%) and 41 (38%) patients in groups M and P, respectively; this difference was significant. Furthermore, the amount of bleeding at 6 h postoperatively was lower in group M than in group P (235 ± 147 vs. 284 ± 175 mL, p = 0.0275). Chest reopening, intubation time, and length of intensive care unit and hospital stays did not differ between the groups. The evaluation of substernal hematoma based on computed tomography yielded a significantly lower for group M than for group P, revealing that the mesh plate was an independent predictor of substernal hematoma prevention.
CONCLUSION
Sternal fixation with a three-piece bioresorbable mesh plate could prevent postoperative sternal displacement, bleeding, and substernal hematoma more than sternal fixation with a pin.

Review
Viscoelastic tests, specifically thromboelastography and rotational thromboelastometry, are increasingly being used in the management of postoperative bleeding in surgical intensive care units (ICUs). However, life-threatening bleeds may complicate the clinical course of many patients admitted to medical ICUs, especially those with underlying liver dysfunction. Patients with cirrhosis have multiple coagulation abnormalities that can lead to bleeding or thrombotic complications. Compared to conventional coagulation tests, a comprehensive depiction of the coagulation process and point-of-care availability are advantages favoring these devices, which may aid physicians in making a rapid diagnosis and instituting early interventions. These tests may help predict bleeding and rationalize the use of blood products in these patients.

OBJECTIVE
Thromboelastography (TEG) is diagnostic modality that analyzes real-time blood coagulation parameters. Clinically, TEG primarily allows for directed blood component resuscitation among patients with acute blood loss and coagulopathy. The utilization of TEG has been widely adopted in among other surgical specialties; however, its use in vascular surgery is less prominent. We aimed to provide an up-to-date review of TEG utilization in vascular and endovascular surgery.
METHODS
Using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a literature review with the Medical Subject Headings (MeSH) terms "TEG and arterial events", "TEG and vascular surgery", "TEG and vascular", "TEG and endovascular surgery", "TEG and endovascular", "TEG and peripheral artery disease", "TEG and prediction of arterial events", "TEG and prediction of complications ", "TEG and prediction of thrombosis", "TEG and prediction of amputation", and "TEG and amputation" was performed in Cochrane and PubMed databases to identify all peer-reviewed studies of TEG utilization in vascular surgery, written between 2000 and 2021 in the English language. The free-text and MeSH subheadings search terms included diagnosis, complications, physiopathology, surgery, mortality, and therapy to further restrict the articles. Studies were excluded if they were not in humans or pertaining to vascular or endovascular surgery. Additionally, case reports and studies with limited information regarding TEG utilization were excluded. Each study was independently reviewed by two researchers to assess for eligibility.
RESULTS
Of the 262 studies identified through the MeSH strategy, 15 studies met inclusion criteria and were reviewed and summarized. Literature on TEG utilization in vascular surgery spanned cerebrovascular disease (n = 3), peripheral arterial disease (n = 3), arteriovenous malformations (n = 1), venous thromboembolic events (n = 7), and perioperative bleeding and transfusion (n = 1). In cerebrovascular disease, TEG may predict the presence and stability of carotid plaques, analyze platelet function before carotid stenting, and compare efficacy of antiplatelet therapy after stent deployment. In peripheral arterial disease, TEG has been used to predict disease severity and analyze the impact of contrast on coagulation parameters. In venous disease, TEG may predict hypercoagulability and thromboembolic events among various patient populations. Finally, TEG can be utilized in the postoperative setting to predict hemorrhage and transfusion requirements.
CONCLUSIONS
This systematic review provides an up-to-date summarization of TEG utilization in multiple facets of vascular and endovascular surgery.

BACKGROUND
Platelet dysfunction has been shown to play a role in postoperative bleeding, however it is not clear whether immature platelets (IP) can induce appropriate homeostasis to prevent excessive bleeding in patients undergoing coronary artery bypass grafting (CABG). The aim of this study was to evaluate the postoperative change in IP count (IPC), IP fraction (IPF) and mean platelet volume (MPV), and to examine their relationship with postoperative bleeding and blood transfusion.
METHODS
One hundred and forty-nine consecutive patients undergoing elective CABG were included in this prospective study. All CABGs were performed by the same surgical team in a standardised method, utilising the on-pump technique. IPC, MPV and IPF were measured pre-operatively, after the completion of surgery, and at the postoperative first, third and fifth days. The primary outcome measure of this study was whether the need for transfusion was associated with IP, IPF, MPV and platelet count.
RESULTS
There was a significant decrease of 7.77% in IPC on the day of the operation. Pre-operative IPC and IPF were correlated with postoperative drainage ( < 0.001), intraoperative blood transfusion ( < 0.001) and intensive care unit blood transfusion ( < 0.001). Pre-operative haemoglobin levels were significantly correlated with length of hospital stay. However, neither pre-operative IPC nor IPF were associated with length of hospital stay. Postoperative IPC was however associated with the length of hospital and intensive care unit stay ( = 0.008 and = 0.009, respectively).
CONCLUSIONS
Pre-operative IPC and IPF were significantly correlated with postoperative drainage and blood transfusion frequency. In patients undergoing CABG, these can be seen as serious guiding parameters in the estimation of postoperative bleeding.
