BACKGROUND
High preoperative fibrinogen levels are associated with reduced bleeding rates after cardiac surgery. Fibrinogen is directly involved in inflammatory processes and is a cardiovascular risk factors. Whether high fibrinogen levels before cardiac surgery are a risk factor for mortality or morbidity remains unclear.
AIMS
This study aimed to examine the association between preoperative fibrinogen levels and mortality and morbidity rates after cardiac surgery.
SETTINGS AND DESIGN
This is a single-center retrospective study.
MATERIAL AND METHODS
Patients (n = 1628) were divided into high (HFGr) and normal (NFGr) fibrinogen level groups, based on the cutoff value of 3.3 g/L, derived from the receiver operating characteristic (ROC) curve analysis. The primary outcome was the 30-day mortality rate. The rates of postoperative complications, including postoperative bleeding and transfusion rates, were examined.
STATISTICAL ANALYSIS
Between-group comparisons were performed with the Mann-Whitney U test and Chi-squared test, as suitable. Model discriminative power was examined with the area under the ROC curve.
RESULTS
The HFGr and NFGr included 1103 and 525 patients, respectively. Mortality rate was higher in the HFGr than in the NFGr (2.7% vs. 1.1%, P = 0.04). The 12-h bleeding volume (280 mL [195-400] vs. 305 mL [225-435], P = 0.0003) and 24-h bleeding volume values (400 mL [300-550] vs. 450 mL [340-620], P < 0.0001) were lower in the HFGr than in the NFGr. However, the rate of red blood cell transfusion during hospitalization was higher in the HFGr than in the NFGr (21.7% vs. 5.9%, P = 0.0103). Major complications were more frequent in the HFGr than in the NFGr.
CONCLUSION
High fibrinogen levels were associated with reduced postoperative bleeding volume and increased mortality and morbidity rates.

Meta-Analysis Review
BACKGROUND
The aim of this meta-analysis and systematic review was to evaluate the association between intraoperative bile cultures and postoperative complications of patients undergoing pancreaticoduodenectomy.
METHODS
A detailed literature search was performed from January 2015 to July 2022 in PubMed, Web of Science, Google Scholar, and EMBASE for related research publications. The data were extracted, screened, and graded independently. An analysis of pooled data was performed, and a risk ratio with corresponding confidence intervals was calculated and summarized.
RESULTS
A total of 8 articles were included with 1,778 pancreaticoduodenectomy patients who had an intraoperative bile culture performed. A systematic review demonstrated that some of the most common organisms isolated in a positive intraoperative bile culture were Enterococcus species, Klebsiella species, and E. coli. Four studies also showed that specific microorganisms were associated with specific postoperative complications (surgical site infection and intra-abdominal abscess). The postoperative complications that were evaluated for an association with a positive intraoperative bile culture were surgical site infections (risk ratio = 2.33, 95% confidence interval [1.47-3.69], P < .01), delayed gastric emptying (risk ratio = 1.23, 95% confidence interval [0.63-2.38], P = n.s.), 90-day mortality (risk ratio = 0.68, 95% confidence interval [0.01-52.76], P = n.s.), postoperative pancreatic hemorrhage (risk ratio = 1.70, 95% confidence interval [0.33-8.74], P = n.s.), intra-abdominal abscess (risk ratio = 1.70, 95% confidence interval [0.38-7.56], P = n.s.), and postoperative pancreatic fistula (risk ratio = 0.97, 95% confidence interval [0.72-1.32], P = n.s.).
CONCLUSION
The cumulative data suggest that a positive intraoperative bile culture has no association with predicting the postoperative complications of delayed gastric emptying, 90-day mortality, postoperative pancreatic hemorrhage, intra-abdominal abscess, or postoperative pancreatic fistula. However, the data also suggest that a positive intraoperative bile culture was associated with a patient developing a surgical site infection.

Review
Delayed bleeding is a major and serious adverse event of endoscopic submucosal dissection (ESD) for early-stage gastrointestinal tumors. The rate of post-ESD bleeding for gastric cancer is higher (around 5%-8%) than that for esophagus, duodenum and colon cancer (around 2%-4%). Although investigations into the risk factors for post-ESD bleeding have identified several procedure-, lesion-, physician- and patient-related factors, use of antithrombotic drugs, especially anticoagulants [direct oral anticoagulants (DOACs) and warfarin], is thought to be the biggest risk factor for post-ESD bleeding. In fact, the post-ESD bleeding rate in patients receiving DOACs is 8.7%-20.8%, which is higher than that in patients not receiving anticoagulants. However, because clinical guidelines for management of ESD in patients receiving DOACs differ among countries, it is necessary for endoscopists to identify ways to prevent post-ESD delayed bleeding in clinical practice. Given that the pharmacokinetics (, plasma DOAC level at both trough and T) and pharmacodynamics (, anti-factor Xa activity) of DOACs are related to risk of major bleeding, plasma DOAC level and anti-FXa activity may be useful parameters for monitoring the anti-coagulate effect and identifying DOAC patients at higher risk of post-ESD bleeding.

OBJECTIVE
To describe the incidence of respiratory complications, postoperative hemorrhage, length of stay, and cost of care in children with mucopolysaccharidosis (MPS) undergoing adenotonsillectomy (AT).
METHODS
Analysis of the 2009, 2012, and 2016 editions of the Healthcare Cost and Utilization Project Kids' Inpatient Database (HCUP KID) identified 24,700 children who underwent AT (40 children with MPS). Demographics, respiratory complications, postoperative hemorrhage, length of stay, and total cost were compared across children with and without MPS.
RESULTS
Children with MPS had a higher likelihood of being male (P < 0.017). There was a higher rate of respiratory complications in children with MPS compared with children without MPS [6/40 (15%) vs. 586/24,660 (2.4%), P < 0.001], which remained significant after adjusting for sex [adjusted odds ratio 6.88 (95% CI 2.87-16.46)]. There was also a higher risk of postoperative hemorrhage [4/40 (10%) vs. 444/24,660 (1.8%), P < 0.001), with sex-adjusted odds ratio of 5.97 (95% CI 2.12-16.86). Median (IQR) length of stay was increased in children with MPS (3 days, 1-4) compared with children without MPS (1 day, 1-2, P < 0.001). There was an increase in median (IQR) charges for hospital stay in children with MPS compared with their peers [$33,016 ($23,208.50-$72,280.50 vs. $15,383 ($9937-$24,462), P < 0.001].
CONCLUSIONS
Children with MPS undergoing AT had an increased risk of respiratory complications, postoperative hemorrhage, longer length of stay, and a higher cost of treatment when compared with children without MPS. This information may help inform interventional, perioperative, and postoperative decision making.

Meta-Analysis
INTRODUCTION
Several surgical techniques have been used during tonsillectomy to reduce complications.
OBJECTIVES
To assess the effects of pillar suture in conjunction with tonsillectomy as compared to tonsillectomy without suture in children.
METHODS
Two authors independently searched five databases (PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database) for studies published as recent as December 2018. Of the included studies, we compared tonsillectomy and pillar suture in combination (suture groups) with tonsillectomy alone,without suture, (control group). Postoperative pain intensity and other morbidities (e.g., postoperative bleeding, palatal hematoma, discomfort, and pillar edema) were measured during the postoperative period.
RESULTS
Postoperative bleeding [primary (OR = 0.47 [0.27; 0.81]) and secondary (OR = 0.14 [0.02; 0.78]) were significantly decreased in the pillar suture group compared to the control group. There were no significant differences between the two groups in postoperative pain at day 7 (SMD = -0.39 [-0.79; 0.00]), palatal hematoma (OR = 5.00 [0.22; 112.88]), palatal discomfort sensation (OR = 2.62 [0.60; 11.46]), site infection (OR = 5.27 [0.24; 113.35]), and velopharyngeal insufficiency (OR = 2.82 [0.11; 74.51]). By contrast, pillar edema (OR = 9.55 [4.29; 21.29]) was significantly increased in the pillar suture group compared to the control group.
CONCLUSIONS
Pillar suture combined with tonsillectomy may reduce postoperative bleeding incidence despite increasing pillar edema in pediatric tonsillectomy. Postoperative pain-relief, palatal hematoma, palatal discomfort sensation, site infection, and velopharyngeal insufficiency were not significantly altered compared to tonsillectomy alone. However, further studies are needed to corroborate the results of this study.

To investigate the effect of preventive measures in reducing postoperative bleeding, which is made for children day surgery on tonsils and adenoids in our hospital, and to clarify its safety and feasibility. A retrospective analysis of 649 patients with children day surgery due to obstructive sleep apnea(OSA) caused by adenoid hypertrophy of tonsil was conducted. All of the patients were admitted to Shanghai Children's Hospital from February 2021 to April 2021. According to whether preventive measures were taken or not, they were divided into the control group and the observation group. The postoperative bleeding rate, bleeding time, and bleeding-related factors of the two groups were compared. There were 4 cases(1.22%) in the observation group and 12 cases(3.74%) in the control group, the postoperative bleeding rate of the observation group was lower than that of the control group(χ²=4.28, =0.039). The postoperative bleeding in the observation group occurred(8.25±2.75) days after surgery while the control group(7.42±1.98) days, which shows no significant difference in postoperative bleeding time between the two groups(χ²=2.601, =0.321). There was no case of postoperative infection in the observation group while 7 cases(58.3%) in the control group(χ²=7.658, =0.036). For children with day surgery of tonsils and adenoids, appropriate optimization measures can be taken for hospital admission evaluation, infection prevention, postoperative observation, publicity and education, which can effectively reduce the incidence of postoperative complications and improve the treatment effect of day surgery.

PURPOSE
Endoscopic nasal and sinus surgery is a surgical procedure frequently performed by otolaryngologists. Postoperative bleeding is detrimental to both healthcare providers and patients. We investigated the epidemiology of postoperative bleeding during endoscopic nasal and sinus surgery and explored possible bleeding triggers.
METHODS
We evaluated the patients who underwent endoscopic nasal and sinus surgery. Data regarding the age, sex, presence of hypertension, and abnormal coagulability, including oral anticoagulants, diagnoses, operative procedures, intraoperative use of drills and blood loss, and postoperative antimicrobial administration of eligible patients, were extracted from medical records and retrospectively reviewed.
RESULTS
One hundred and eighty-six patients underwent endoscopic nasal or sinus surgery during the study period, and postoperative bleeding occurred in 9 patients (4.8%). Posterior nasal neurotomy (PNN) was the procedure most likely to cause postoperative bleeding (4 surgeries, 13.3%). Postoperative antimicrobial administration significantly reduced the incidence of postoperative bleeding (p = 0.04).
CONCLUSIONS
Postoperative bleeding requiring intervention occurs in 4.8% of cases, and PNN is associated with a high risk of postoperative bleeding. Wound infection is a potential cause of postoperative bleeding, and antimicrobial administration should be considered in addition to local treatment.

OBJECTIVE
Postpancreatectomy hemorrhage is a life-threatening complication. Hemorrhage occurring >24 hours after the index operation is defined as late hemorrhage. This study was performed to analyze the therapeutic management and prognostic factors of late hemorrhage after pancreatectomy.
METHODS
We identified 87 patients with late hemorrhage among 2031 patients who underwent pancreatic surgery from January 2013 to December 2017. The patients' demographic characteristics, perioperative treatment, hemorrhage details, and prognosis were retrospectively analyzed.
RESULTS
Of the 87 patients, 53 were men. Bleeding occurred at a mean of 8.9 ± 6.0 days postoperatively. Extraluminal and intraluminal hemorrhage occurred in 58 and 29 patients, respectively. The primary intervention was successful in 66 patients, and 16 patients required a secondary intervention. The primary and total recovery rates were 72.4% and 89.7%, respectively. Of the 87 patients, 9 died. Male sex, hemorrhage on a later postoperative day, a significantly decreased hemoglobin level, and pancreatic fistula showed statistical significance as possible risk factors for mortality.
CONCLUSIONS
Male sex, hemorrhage on a later postoperative day, a significantly decreased hemoglobin level, and pancreatic fistula are possible risk factors for mortality in patients with late hemorrhage after pancreatectomy. Hemorrhage is a dynamic process, and a secondary intervention may be necessary.

Review
BACKGROUND
Vitrectomy is an established treatment for the complications of proliferative diabetic retinopathy (PDR). However, a number of complications can occur during and after vitrectomy for PDR. These include bleeding and the creation of retinal holes during surgery, and bleeding, retinal detachment and scar tissue on the retina after surgery. These complications can limit vision, require further surgery and delay recovery. The use of anti-vascular endothelial growth factor (anti-VEGF) agents injected into the eye before surgery has been proposed to reduce the occurrence of these complications. Anti-VEGF agents can reduce the amount and vascularity of abnormal new vessels associated with PDR, facilitating their dissection during surgery, reducing intra- and postoperative bleeding, and potentially improving outcomes.
OBJECTIVES
To assess the effects of perioperative anti-VEGF use on the outcomes of vitrectomy for the treatment of complications for proliferative diabetic retinopathy (PDR).
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; which contains the Cochrane Eyes and Vision Trials Register; 2022, Issue 6); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. The date of the search was 22 June 2022.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that looked at the use of anti-VEGFs and the incidence of complications in people undergoing vitrectomy for PDR. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed and extracted the data. We used the standard methodological procedures expected by Cochrane. The critical outcomes of the review were the mean difference in best corrected visual acuity (BCVA) between study arms at six (± three) months after the primary vitrectomy, the incidence of early postoperative vitreous cavity haemorrhage (POVCH, within four weeks postoperatively), the incidence of late POVCH (occurring more than four weeks postoperatively), the incidence of revision surgery for POVCH within six months, the incidence of revision surgery for recurrent traction/macular pucker of any type and/or rhegmatogenous retinal detachment within six months and vision-related quality of life (VRQOL) measures. Important outcomes included the proportion of people with a visual acuity of counting fingers (1.8 logMAR or worse), the number of operative retinal breaks reported and the frequency of silicone oil tamponade required at time of surgery.
MAIN RESULTS
The current review includes 28 RCTs that looked at the pre- or intraoperative use of intravitreal anti-VEGFs to improve the outcomes of pars plana vitrectomy for complications of PDR. The studies were conducted in a variety of countries (11 from China, three from Iran, two from Italy, two from Mexico and the remaining studies from South Korea, the UK, Egypt, Brazil, Japan, Canada, the USA, Indonesia and Pakistan). The inclusion criteria for entry into the studies were the well-recognised complications of proliferative retinopathy: non-clearing vitreous haemorrhage, tractional retinal detachment involving the macula or combined tractional rhegmatogenous detachment. The included studies randomised a total of 1914 eyes. We identified methodological issues in all of the included studies. Risk of bias was highest for masking of participants and investigators, and a number of studies were unclear when describing randomisation methods and sequence allocation. Participants receiving intravitreal anti-VEGF in addition to pars plana vitrectomy achieved better BCVA at six months compared to people undergoing vitrectomy alone (mean difference (MD) -0.25 logMAR, 95% confidence interval (CI) -0.39 to -0.11; 13 studies, 699 eyes; low-certainty evidence). Pre- or intraoperative anti-VEGF reduced the incidence of early POVCH (12% versus 31%, risk ratio (RR) 0.44, 95% CI 0.34 to 0.58; 14 studies, 1038 eyes; moderate-certainty evidence). Perioperative anti-VEGF use was also associated with a reduction in the incidence of late POVCH (10% versus 23%, RR 0.47, 95% CI 0.30 to 0.74; 11 studies, 579 eyes; high-certainty evidence). The need for revision surgery for POVCH occurred less frequently in the anti-VEGF group compared with control, but the confidence intervals were wide and compatible with no effect (4% versus 13%, RR 0.44, 95% CI 0.15 to 1.28; 4 studies 207 eyes; moderate-certainty evidence). Similar imprecisely measured effects were seen for revision surgery for rhegmatogenous retinal detachment (5% versus 11%, RR 0.50, 95% CI 0.15 to 1.66; 4 studies, 145 eyes; low-certainty evidence). Anti-VEGFs reduce the incidence of intraoperative retinal breaks (12% versus 31%, RR 0.37, 95% CI 0.24 to 0.59; 12 studies, 915 eyes; high-certainty evidence) and the need for silicone oil (19% versus 41%, RR 0.46, 95% CI 0.27 to 0.80; 10 studies, 591 eyes; very low-certainty evidence). No data were available on quality of life outcomes or the proportion of participants with visual acuity of counting fingers or worse.
AUTHORS' CONCLUSIONS
The perioperative use of anti-VEGF reduces the risk of late POVCH, probably results in lower early POVCH risk and may improve visual outcomes. It also reduces the incidence of intraoperative retinal breaks. The evidence is very uncertain about its effect on the need for silicone oil tamponade. The reported complications from its use appear to be low. Agreement on variables included and outcome standardisation is required in trials studying vitrectomy for PDR.

Meta-Analysis Review
Although most physicians are comfortable managing the limited anticoagulant effect of aspirin, the recent administration of potent P2Y receptor inhibitors in patients undergoing cardiac surgery remains a dilemma. Guidelines recommend discontinuation of potent P2Y inhibitors 5- to- 7 days before surgery to reduce the risk of postoperative hemorrhage. Such a strategy might not be feasible before urgent surgery, due to ongoing myocardial ischemia or in patients at high risk for thromboembolic events. Recently, different point-of-care devices to assess functional platelet quality have become available for clinical use. The aim of this narrative review was to evaluate the implications and potential benefits of platelet function monitoring in guiding perioperative management and therapeutic options in patients treated with antiplatelets, including aspirin or P2Y receptor inhibitors, undergoing cardiac surgery. No objective superiority of one point-of-care device over another was found in a large meta-analysis. Their accuracy and reliability are generally limited in the perioperative period. In particular, preoperative platelet function testing has been used to assess platelet contribution to bleeding after cardiac surgery. However, predictive values for postoperative hemorrhage and transfusion requirements are low, and there is a significant variability between and within these tests. Further, platelet function monitoring has been used to optimize the preoperative waiting period after cessation of dual antiplatelet therapy before urgent cardiac surgery. Furthermore, studies assessing their value in therapeutic decisions in bleeding patients after cardiac surgery are scarce. A general and liberal use of perioperative platelet function testing is not yet recommended.
