Meta-Analysis
BACKGROUND AND AIM
Preventing rebleeding is crucial, but the best prevention technique for patients with cirrhosis and portal vein thrombosis (PVT) remains debatable. Therefore, this systematic review and meta-analysis compared a transjugular intrahepatic portosystemic shunt (TIPS) with endoscopic therapy (ET) plus nonselective beta-blockers (NSBBs) for preventing variceal rebleeding in this patient population.
METHODS
The PubMed, Embase, Cochrane Library, and Web of Science databases were searched from their inception until May 18, 2023. The studies were screened using predetermined criteria, relevant data were extracted, and pooled analyses were performed using the Reviewer Manager 5.4.1 software.
RESULTS
We retrieved 1032 studies, of which 5 studies comprising a total of 272 patients were included. The postoperative variceal rebleeding rate was significantly lower in the TIPS group than in the ET + NSBBs group (odds ratio [OR] = 0.19, 95% confidence interval [CI] = 0.11-0.35, P < 0.05, I = 0%), but the portal vein recanalization rate was higher (OR = 7.92, 95% CI = 3.04-20.67, P < 0.05, I = 0%). The rates of hepatic encephalopathy (HE) and mortality did not differ between the groups.
CONCLUSIONS
Our results suggest that TIPS prevents variceal rebleeding without increasing the hepatic encephalopathy risk more effectively than ET plus NSBBs, but this benefit did not translate into improved survival. Thus, it may be preferable to ET plus NSBBs for preventing variceal rebleeding in patients with cirrhosis and PVT. However, more large-scale and multicenter randomized controlled trials involving other patient populations are required to verify the clinical efficacy of both these treatments and ensure generalizability.

Meta-Analysis
BACKGROUND
In on-pump cardiac surgery, the albumin priming strategy could maintain colloid osmotic pressure better than crystalloid solutions and reduce excessive perioperative fluid balance. However, a high-quality meta-analysis is required to compare the safety of these approaches in perioperative red blood cell (RBC) transfusions. Owing to limited direct evidence, we conducted a network meta-analysis (NMA) to increase the pool of studies and provide indirect evidence.
METHODS
The pre-defined primary outcomes were intraoperative and the first 24 h postoperative RBC transfusion volume in units. The pre-defined secondary outcome was postoperative blood loss (the first 24 h). We reviewed all randomized controlled trials comparing albumin, crystalloid, and artificial colloid priming strategies. Studies that only displayed pre-defined outcomes could be included. A pairwise meta-analysis was performed on studies that directly compared the pre-defined outcomes between albumin and crystalloids. Additionally, a random-effects network meta-analysis (NMA) model was employed to generate indirect evidence for the pre-defined outcomes between albumin and crystalloids.
RESULTS
The literature search identified 830 studies,10 of which were included in the final analysis. Direct meta-analysis indicated that crystalloid priming significantly decreased total perioperative RBC transfusions (MD: -0.68U; 95%CI: -1.26, -0.09U; P = 0.02) and intraoperative RBC transfusions (MD: -0.20U; 95%CI: -0.39, -0.01U; P = 0.03) compared to albumin. Postoperative RBC transfusions showed a decreasing trend in the crystalloid group; however, the difference was not statistically significant. (MD: -0.16U; 95%CI: -0.45, 0.14U; P = 0.30). After including indirect evidence, the NMA results continued to demonstrate a higher RBC receiving with the albumin priming strategy compared to crystalloids, although the differences did not reach statistical significance. For postoperative blood loss, direct evidence showed no significant differences between albumin and crystalloid priming strategies. However, NMA evidence displayed that albumin exist higher probability of reducing postoperative blood loss than crystalloid.
CONCLUSION
Both direct and NMA evidence indicated that the albumin priming strategy resulted in more perioperative RBC transfusions than crystalloids. Considering the additional blood management burden, the application of an albumin-priming strategy in on-pump cardiac surgery still needs more consideration.

OBJECTIVE
Tracheoinnominate artery fistulas (TIFs) are a rare but deadly complication of tracheostomy. Tracheoinnominate artery fistula cases in the literature were summarized in order to understand mortality associations.
METHODS
MEDLINE was searched for studies reporting individual characteristics of patients with TIFs after tracheostomy, excluding cases without tracheostomy or with additional procedures at the tracheostomy site. This study followed PRISMA guidelines.
RESULTS
121 TIF patients from 18 case series and 46 case reports were included. The median age was 40 years, and 5% were male. The overall mortality rate was 64.%. There were differences in mortality between cases that presented initially with vs without sentinel bleeding (odds ratio [OR] .34; CI [confidence interval] .16-.73; = .006). The mortality rate also differed in whether or not the tracheostomy cuff was over-inflated for temporary hemostasis during resuscitation (OR 3.57 (CI 1.57-8.09); = .002). Treatment compared to no treatment had lower mortality rates (OR .11 (CI 0.04-.32); < .001); no differences were found if treatment was endovascular vs open surgical.
CONCLUSIONS
Mortality is a major concern after detection of a TIF and resuscitation paired with endovascular or open surgical intervention is imperative. Rapidly investigating sentinel bleeds and intervening upon hemorrhage with temporary cuff over inflation may lead to improved outcomes.

Meta-Analysis Review
Pedicled ligament flaps during pancreatoduodenectomy are associated with reduced hemorrhage from hepatic artery and gastroduodenal artery stump during pancreatoduodenectomy: a systematic review, meta-analysis and trial sequential analysis.
BACKGROUND
The aim of this study was to investigate whether pedicled ligament flaps (PLF) covering around the hepatic and gastroduodenal artery stump can provide better clinical outcomes in pancreatoduodenectomy (PD).
METHODS
We conducted a comprehensive search of databases (inception to January 2023) to identify studies comparing PD with or without PLF covering the skeletonized arteries. The perioperative and postoperative outcomes were compared. Pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated using fixed-effects models.
RESULTS
Ten studies were included in the qualitative synthesis. Six studies with 3538 patients met the inclusion criteria for the meta-analysis. Patients in the PLF group had a significantly lower rate of PPH from the hepatic artery or gastroduodenal artery stump (H/G PPH) (OR: 0.41; 95 % CI, 0.22-0.75; P < 0.01) and overall PPH (OR: 0.65; 95 % CI, 0.46-0.93; P = 0.02). There were no significant differences between the two groups in terms of morbidity, grade B/C postoperative pancreatic fistula (B/C POPF), delayed gastric emptying (DGE), reoperation, or mortality.
CONCLUSION
Prophylactic pedicled ligament flaps covering around the skeletonized arteries significantly reduced overall PPH and H/G PPH, and it seemed to have no obvious influence on other complications.

OBJECTIVE
The assessment of the relative impacts of uterine artery embolization (UAE) treatment for female patients is a critical field that informs clinical decisions, yet there is a noticeable scarcity of high-quality, long-term comparative studies. This meta-analysis aimed to focus on the pregnancy rate and outcomes in female patients following UAE and to conduct subgroup analyses based on different patient populations or various control treatments.
METHODS
A systematic literature search was conducted on 2 August 2023 through the Web of Science, PubMed, Embase, and the Cochrane Library of Clinical Trials for all potential studies. Relative risks (RRs) with 95% confidence intervals (CIs) were applied to compare pregnancy rates and outcomes between the UAE group and the control group. Heterogeneity was evaluated statistically by using the chi-square-based Cochran's Q test and Higgins I statistics, and 95% prediction interval (PI). Software R 4.3.1 and Stata 12.0 were used for meta-analysis. The trial sequential analysis (TSA) was performed with TSA v0.9.5.10 Beta software.
RESULTS
A total of 15 eligible studies (11 cohort studies, 3 randomized controlled trials, and 1 non-randomized clinical trial) were included in this meta-analysis. The overall results revealed that UAE significantly decreased postoperative pregnancy rate [RR (95% CI): 0.721 (0.531-0.979), 95% PI: 0.248-2.097] and was associated with an increased risk of postoperative PPH [RR (95% CI): 3.182 (1.319-7.675), 95% PI: 0.474-22.089]. Analysis grouped by population indicated that UAE decreased the risk of preterm delivery [RR (95% CI): 0.326 (0.128-0.831), = 0.019] and cesarean section [RR (95% CI): 0.693 (0.481-0.999), = 0.050] and increased the risk of placenta previa [RR (95% CI): 8.739 (1.580-48.341), = 0.013] in patients with UFs, CSP, and PPH, respectively. When compared with myomectomy, HIFU, and non-use of UAE, UAE treatment was associated with the reduced risks of preterm delivery [RR (95% CI): 0.296 (0.106-0.826)] and cesarean section [(95% CI): 0.693 (0.481-0.999), = 0.050] and increased placenta previa risk [RR (95% CI): 10.682 (6.859-16.636)], respectively.
CONCLUSION
UAE treatment was associated with a lower postoperative pregnancy rate and increased risk of PPH. Subgroup analysis suggested that UAE was shown to decrease the risk of preterm delivery and cesarean section and increase placenta previa risk.https://www.crd.york.ac.uk/prospero/, Identifier CRD42023448257.

Meta-Analysis Review
OBJECTIVE
To determine the risk of bleeding after minor extraction in patients on different antiplatelet therapy (APT) regimens.
STUDY DESIGN
A search was conducted using PubMed and Google Scholar. Thirty-five papers were included in the systematic review, of which 23 papers provided the requisite information for meta-analysis. Subgroups were created based on the controls, as follows: (1) no control, (2) healthy control, and (3) interrupted APT control. In a meta-analysis, the studies were further subdivided into immediate and delayed bleeding.
RESULTS
No immediate or delayed bleeding risk was found in patients treated with aspirin vs healthy controls (relative risk [RR] = 1.26; P = .5 and RR = 2.17; P = .09, respectively). A higher immediate bleeding was recorded for patients on single nonaspirin APT vs those in the healthy population (RR = 3.72; P = .0009). A high risk of bleeding was recorded in patients receiving dual APT compared with healthy controls for immediate (RR = 10.3; P < .0001) and delayed (RR = 7.72; P = .001) bleeding. Dual APT continuation showed a higher risk of immediate bleeding (RR = 2.13) than interrupted APT, but the difference was insignificant (P = .07).
CONCLUSIONS
Dental extraction can be performed safely in patients on aspirin monotherapy. In contrast, patients receiving dual APT should be considered at risk for immediate and continued bleeding.

Meta-Analysis
To systematically evaluate the effects of comprehensive nursing interventions on wound pain and complications in patients after tonsillectomy, with a view to providing a reference basis for future post-tonsillectomy care. According to the developed literature search strategy, PubMed, Web of Science, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure database were systematically searched, from database inception to October 2023, for randomised controlled trials (RCTs) of the application of comprehensive nursing interventions in patients undergoing tonsillectomy. Two researchers independently screened the literature, evaluated the risk of bias of the included studies and extracted data in strict accordance with the inclusion and exclusion criteria. RevMan 5.4 software was applied for data analysis. Overall, 18 RCTs involving 1954 patients were included, including 967 in the comprehensive nursing group and 987 in the conventional nursing group. The analyses revealed that compared with conventional nursing, patients who received comprehensive nursing interventions had lower postoperative wound pain scores (standardised mean difference [SMD]: -2.30, 95% confidence interval [CI]: -2.19 to -1.70, p < 0.00001), shorter hospital stays (SMD: -1.95, 95% CI: -2.39 to -1.51, p < 0.00001), incidence of postoperative haemorrhage (1.60% vs. 6.41%, odds ratio [OR]: 0.29, 95% CI: 0.12-0.70, p = 0.006) and complication rates (4.21% vs. 19.01%, OR: 0.19, 95% CI: 0.11-0.32, p < 0.00001) was lower. This study concludes as follows: comprehensive nursing intervention applied to tonsillectomy can significantly reduce patients' postoperative wound pain, shorten hospital stay, reduce postoperative bleeding and postoperative complications, which is worthy of being promoted and applied in the clinic.

The effect of general anesthesia and conscious sedation in endovascular thrombectomy for acute ischemic stroke: an updated meta-analysis of randomized controlled trials and trial sequential analysis.
OBJECTIVES
General anesthesia (GA) and conscious sedation (CS) are common methods for endovascular thrombectomy (EVT) in acute ischemic stroke (AIS). However, the risks and benefits of each strategy are unclear. This study aimed to summarize the latest RCTs and compare the postoperative effects of the two methods on EVT patients.
MATERIALS AND METHODS
We systematically searched the database for GA and CS in AIS patients during EVT. The retrieval time was from the creation of the database until March 2023. The quality of the studies was evaluated using the Cochrane risk of bias tool. Random-effects or fixed-effects meta-analyses were used to assess all outcomes.
RESULTS
We preliminarily identified 304 studies, of which 8 were included. Based on the pooled estimates, there were no significant differences between the GA group and the CS group in terms of good functional outcomes (mRS0-2) and mortality rate at 3 months (RR = 1.09, 95% CI: 0.95-1.24, = 0.23) (RR = 0.95, 95% CI: 0.75-1.22, = 0.70) as well as in NHISS at 24 h after treatment (SMD = -0.01, 95% CI: -0.13 to 0.11, = 0.89). However, the GA group had better outcomes in terms of achieving successful recanalization of the blood vessel (RR = 1.13, 95% CI: 1.07-1.19, < 0.0001). The RR value for the risk of hypotension was 1.87 (95% CI: 1.42-2.47, < 0.00001); for pneumonia, RR was 1.43 (95% CI: 1.07-1.90, = 0.01); and for symptomatic intracerebral hemorrhage, RR was 0.94 (95% CI: 0.74-1.26, = 0.68). The pooled RR value for complications after intervention was 1.03 (95% CI, 0.87-1.22, = 0.76).
CONCLUSION
In patients undergoing EVT for AIS, GA, and CS are associated with similar rates of functional independence. Further trials of a larger scale are needed to confirm these findings.

Meta-Analysis
BACKGROUND
Short-stay joint replacement programmes are used in many countries but there has been little scrutiny of safety outcomes in the literature. We aimed to systematically review evidence on the safety of short-stay programmes versus usual care for total hip (THR) and knee replacement (KR), and optimal patient selection.
METHODS
A systematic review and meta-analysis. Randomised controlled trials (RCTs) and quasi-experimental studies including a comparator group reporting on 14 safety outcomes (hospital readmissions, reoperations, blood loss, emergency department visits, infection, mortality, neurovascular injury, other complications, periprosthetic fractures, postoperative falls, venous thromboembolism, wound complications, dislocation, stiffness) within 90 days postoperatively in adults ≥ 18 years undergoing primary THR or KR were included. Secondary outcomes were associations between patient demographics or clinical characteristics and patient outcomes. Four databases were searched between January 2000 and May 2023. Risk of bias and certainty of the evidence were assessed.
RESULTS
Forty-nine studies were included. Based upon low certainty RCT evidence, short-stay programmes may not reduce readmission (OR 0.95, 95% CI 0.12-7.43); blood transfusion requirements (OR 1.75, 95% CI 0.27-11.36); neurovascular injury (OR 0.31, 95% CI 0.01-7.92); other complications (OR 0.63, 95% CI 0.26-1.53); or stiffness (OR 1.04, 95% CI 0.53-2.05). For registry studies, there was no difference in readmission, infection, neurovascular injury, other complications, venous thromboembolism, or wound complications but there were reductions in mortality and dislocations. For interrupted time series studies, there was no difference in readmissions, reoperations, blood loss volume, emergency department visits, infection, mortality, or neurovascular injury; reduced odds of blood transfusion and other complications, but increased odds of periprosthetic fracture. For other observational studies, there was an increased risk of readmission, no difference in blood loss volume, infection, other complications, or wound complications, reduced odds of requiring blood transfusion, reduced mortality, and reduced venous thromboembolism. One study examined an outcome relevant to optimal patient selection; it reported comparable blood loss for short-stay male and female participants (p = 0.814).
CONCLUSIONS
There is low certainty evidence that short-stay programmes for THR and KR may have non-inferior 90-day safety outcomes. There is little evidence on factors informing optimal patient selection; this remains an important knowledge gap.

OBJECTIVE
Post implantation syndrome (PIS) is an early systemic inflammatory response following endovascular aortic repair (EVAR). The response is variable in patients and the clinical significance of PIS upon outcomes is unknown. This study aims to evaluate the incidence, risk factors, and prognostic implication of PIS.
METHODS
Systematic literature review and analysis was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and Cochrane guidelines of PubMed, Scopus, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials. Eligible English-language studies regarding PIS after infrarenal EVAR were included, after removing duplicates.
RESULTS
After screening, 31 studies were included. A total of 2847 patients were reviewed, with mean age of 70.7 years, of which 2012 (90.4%) were male, with a pooled mean follow-up of 26.1 months. PIS was reported in 25.3% of cases, with mean aneurysm diameter of 56.4 cm. Polytetrafluoroethylene (PTFE) grafts were utilized in 794 patients (27.9%) with polyester in 1839 (64.6%). White blood cell count, C-reactive protein, interleukin (IL)-6, IL-8, and IL-10 levels were all significantly elevated postoperatively. Thirty-day outcomes included type I endoleak rate of 0.8%, type II endoleak rate of 1.7%, reintervention rate of 0.35%, and mortality rate of 0.25%. Subgroup pooled analysis of patients with PIS (n = 309) vs No-PIS (n = 691) revealed that polyester (n = 642), rather than PTFE (n = 234) grafts, were associated with a higher rate of PIS (94.8% vs 3.7%; P = .0001), White blood cell count was higher in the PIS group both preoperatively (7.61 vs 6.76 × 10/L; P = .04) and postoperatively (15.0 vs 9.8 × 10/L; P = .0007) and IL-6 levels were higher in the PIS group postoperatively (98.6 vs 25.2 pg/mL; P = .02). Aneurysm diameter and amount of chronic or new thrombus within the aneurysm sac was not identified as a risk factor for PIS. Pooled outcomes of patients with PIS vs No-PIS demonstrated a significantly higher rate of 30-day mortality (0.6% vs 0%; P = .03) and major adverse cardiac events (5.8% vs 0.43%; P < .0001) without any differences seen in reintervention or 30-day type I or type II endoleaks.
CONCLUSIONS
This systematic review suggests that polyester grafts are strongly associated with PIS compared with PTFE. Interestingly, this report is suggestive of an association between 30-day mortality and major adverse cardiac events and PIS. Given these clinical sequelae, consideration for use of PTFE over polyester grafts to reduce the incidence of PIS may be a simple step to improve overall outcome. Further, exploration of the relationship between inflammatory mediators associated with PIS and mortality and cardiac complications may engender deeper understanding of risks, leading to eventual mitigation of harm for patients experiencing PIS.
