Review
OBJECTIVES
Non-operative management (NOM) of blunt abdominal trauma has become increasingly common in hemodynamically stable patients. There are known complications of NOM from undrained intra-abdominal fluid accumulations including hemorrhage and peritonitis that require delayed operation. Thus, delayed operation can be considered as part of the overall management plan, instead of failure, of NOM. The aim of this scoping review is to establish key concepts regarding delayed laparoscopic peritoneal washout (DLPW) following NOM of blunt abdominal trauma patients.
METHODS
MEDLINE, EMBASE, CENTRAL, and gray literature were systematically searched. Studies were included if they investigated or reported on the use of delayed laparoscopy involving peritoneal washout following NOM of blunt abdominal trauma patients. Bibliographies of included studies were manually reviewed to identify additional articles for inclusion.
RESULTS
From 910 citations, 28 studies met inclusion criteria. This included seven case reports, eleven case series or observational cohort studies, six review articles, two management guidelines, one textbook chapter, and one randomized clinical trial. For those reported, medium grade liver injuries proved most common (95.2%). Indications for DLPW were primarily clinical features and changes in imaging findings, highlighting the importance of close observation. Authors reported clinical improvement after DLPW regarding symptomatology, vital signs, and biochemistry. A relatively high transfusion demand was reported with a mean of four units of packed red blood cells pre-operatively. Length of stay and post-operative complications were consistent with previously reported experiences with blunt abdominal injuries.
CONCLUSIONS
DLPW is beneficial in blunt abdominal trauma patients following NOM with improvement in symptoms, SIRS features, and a possible reduction in hospital length of stay. This study is limited by low-quality evidence and skewing of data toward isolated hepatic injuries. Future prospective cohort study comparing NOM with and without DLPW is required.

Meta-Analysis
The role of polyglycolic acid sheets in the management of post-endoscopic submucosal dissection gastrointestinal bleeding and esophageal stricture: A PRISMA compliant systematic review and meta-analysis.
BACKGROUND
As a relatively minimally invasive technique, endoscopic submucosal dissection (ESD) is widely used for the treatment of gastrointestinal lesions. However, it is associated with complications, such as postoperative bleeding, stricture, and perforation. A covering method using polyglycolic acid (PGA) sheets for ESD-induced ulcers has been reported to be effective in reducing the risk of post-ESD bleeding and esophageal stricture. Herein, we conducted a systematic review and meta-analysis to evaluate the role of PGA sheets in the prevention of gastrointestinal bleeding and esophageal stricture after ESD.
METHODS
We searched PubMed, Web of Science, and the Cochrane Library databases on October 15, 2019. All eligible articles were selected based on the predefined inclusion and exclusion criteria. The main outcomes were the rates of post-ESD gastrointestinal bleeding and esophageal stricture. Cochrane's Q statistic and I2 test were used to identify heterogeneity between the studies. When there was no obvious heterogeneity (I2 < 50%, P > .1), a fixed-effect model was used. When there was obvious heterogeneity (I2 > 50%, P < .1), a random effect model was used. Funnel plots and the Egger regression test were used to assess publication bias.
RESULTS
Fifteen articles were included in the meta-analysis, of which 7 were exclusively about the use of PGA sheets to prevent postoperative gastrointestinal bleeding, and the remaining reported the use of PGA sheets to prevent postoperative esophageal stenosis. Our analysis showed that preventive therapy with PGA sheets decreased the rates of post-ESD gastrointestinal bleeding (risk ratio [RR] = 0.35, 95% confidential interval [CI]: 0.19-0.64, P < .001) and esophageal stricture (RR = 0.46, 95% CI: 0.27-0.79, P = .005), and the gastrointestinal bleeding and esophageal stricture rates after preventive treatment with PGA sheets were 5.7% (95% CI: 3.6%-8.8%) and 20.6% (95% CI: 14.5%-28.4%), respectively.
CONCLUSION
The utilization of PGA sheets after ESD has an excellent outcome in reducing the risk of postoperative gastrointestinal bleeding and esophageal stricture.

Review
PURPOSE
This systematic review aims to summarize the evidence investigating the effectiveness and safety of the Surpass Evolve-Flow Diverter (SE-FD) to treat brain aneurysms.
METHOD
We searched MEDLINE, EMBASE, CINAHL, Web of Science, and Cochrane Library from January 2019 to 29 March 2022. Terms related to the "intracranial aneurysm" and "surpass evolve flow diverter" concepts were used to search the databases; Medical Subject Headings (MeSH) and reference hand search were also utilized.
RESULTS
The searches primarily identified 1586 documents. A total of five studies (four case series and one cohort) were included in this review. In the included studies, 192 (74 male and 118 females) patients with 198 aneurysms were involved. In total, 153 SE-FDs were used to treat 145 aneurysms. Complete occlusion was achieved in 69/145 (48%) cases and near-complete occlusion in 24/145 (17%) cases from aneurysms treated with SE-FD. Reported postoperative complications included stent thrombosis ( = 4 patients), hemorrhage ( = 5 patients), ischemia ( = 9 patients), and neurological complications ( = 12 patients). In total, four deaths were reported with only one related to the SE-FD procedure.
CONCLUSION
The results of this review are based on observational data, due to the absence of clinical trials. The findings of the included studies suggest that the effectiveness of the SE-FD procedure is lower than previous FDs but the safety is similar. The included studies also suggested that SE-FD has navigability and resistance to twisting, which makes the procedure an easier method to treat aneurysms that are proximal and distal to the circle of Willis deployment. This review highlights the urgency to conduct clinical trials to confirm these suggestions.

One of the most common surgeries in elderly patients is eye surgery. An increasing number of patients undergoing ambulatory eye surgery are on antithrombotic therapy. These drugs may increase the risk of perioperative bleeding associated with ophthalmic needle blocks and/or eye surgery. Intraoperative bleeding and postoperative hemorrhagic complications may lead to the loss of vision or even eyes. On the other hand, stopping anticoagulants and antiplatelets before the surgery may increase the risk of thrombotic events with potentially life-threatening complications. The aim of this narrative review is to provide a systematic review of the published evidence for the perioperative antithrombotic management of patients undergoing different types of eye surgery in ambulatory settings. A comprehensive review of the English-language medical literature search utilizing PubMed, Ovid Medline® and Google Scholar from January 2015 to December 2018 was performed. The database searches included studies providing evidence relevant to ambulatory eye surgery and perioperative antiplatelet medications and anticoagulants. Updated recommendations will be given for continuation, discontinuation, and modification of antithrombotic agents in order to optimize the management of antithrombotic therapies in outpatients scheduled for eye surgery.

Meta-Analysis Review
BACKGROUND
Direct oral anticoagulants (DOACs) have been increasingly used as anticoagulation therapy in the postoperative period. However, their effectiveness in post-cardiac surgical atrial fibrillation is yet to be determined.
METHODS
We conducted a meta-analysis, searching three international databases from 1 January 2003 to 26 January 2022 for studies reporting on DOACs in at least 10 adult patients (>18 yr of age) with post-cardiac surgical atrial fibrillation. The primary outcomes were major neurological events and bleeding; secondary outcomes were mortality, hospital and ICU length of stay, cost, and other complications from therapy. We included studies of any design, including RCTs, cohort studies with and without propensity score matching methods, and single-armed case series.
RESULTS
Twelve studies (8587 DOACs; 8315 warfarin) were included in this meta-analysis. The incidences of postoperative bleeding and major neurological events with DOACs were 7.3% (95% confidence interval [CI]: 3.4-14.7%) and 2.2% (95% CI: 0.9-4.9%), respectively. The incidence of major neurological events was lower in high-risk patients, including those with hypertension and higher CHADS-VASc score, whereas patients with prior transient ischaemic attack or stroke had higher incidence of bleeding. Trial sequential analysis revealed that the cumulative Z-curve crossed the conventional boundary of benefit. Compared with warfarin, DOACs reduced the risk of bleeding (relative risk [RR] 0.74; 95% CI: 0.62-0.89; P=0.0011) and major neurological events (RR 0.63; 95% CI: 0.48-0.83; P=0.0012) but not mortality (RR 1.02; 95% CI: 0.77-1.35; P=0.090).
CONCLUSIONS
DOACs reduced bleeding and major neurological events in patients with post-cardiac surgical atrial fibrillation, appearing safer than warfarin in this context. However, which specific DOAC provides the most effective anticoagulation in this patient population needs further investigation.

Meta-Analysis Review
Background Intracranial hemorrhage (ICH) is one of the main causes for lack of surgery in patients with infective endocarditis (IE), despite the presence of surgical indications. We aimed to evaluate the impact of early surgery in patients with IE and with ICH on postoperative neurological deterioration and all-cause mortality and to elucidate the risk of 30-day mortality in patients who were denied surgery. Methods and Results Three libraries (MEDLINE, EMBASE, and Cochrane Library) were assessed. The primary outcome was all-cause mortality, and the secondary outcome was neurological deterioration. Inverse variance method and random model were performed. We identified 16 studies including 355 patients. Nine studies examined the impact of surgical timing (early versus late) and were included in the meta-analysis. Only one study examined the fate of patients with IE and with ICH who were treated conservatively despite having an indication for cardiac surgery, showing higher mortality rates than those who underwent surgery (11.8% versus 2.5%). We found no significant association between early surgery, regardless of its definition, and a higher mortality (odds ratio [OR], 1.69; 95% CI, 0.95-3.02). Early surgery was associated with higher risk for neurological deterioration (OR, 2.00; 95% CI, 1.10-3.65). Conclusions Cardiac surgery for IE within 30 days of ICH was not associated with higher mortality, but with an increased rate of neurological deterioration. The 30-day mortality in patients with IE and with ICH who were denied surgery has not yet been sufficiently investigated. This patient group should be analyzed in future studies in more detail.

INTRODUCTION
The safety and efficacy of tirofiban in intravenous thrombolysis (IVT) bridging to mechanical thrombectomy in patients with acute ischemic stroke (AIS) is unknown. The purpose of this meta-analysis was to evaluate the safety and efficacy of tirofiban in IVT bridging to mechanical thrombectomy in acute ischemic stroke.
METHODS
We systematically searched PubMed, EMBASE, Web of Science, and The Cochrane Library, CNKI, and Wan Fang databases for randomized controlled trials and observational studies (case-control studies and cohort studies) comparing the tirofiban and non-tirofiban groups in AIS intravenous thrombolysis bridging to mechanical thrombectomy (Published by November 20, 2021). Our primary safety endpoints were symptomatic cerebral hemorrhage (sICH), intracranial hemorrhage (ICH), postoperative re-occlusion, and 3-month mortality; the efficacy endpoints were 3-month favorable functional outcome (MRS ≤ 2) and successful recanalization rate (modified thrombolytic therapy in cerebral infarction (mTICI) 2b or 3).
RESULTS
A total of 7 studies with 1,176 patients were included in this meta-analysis. A comprehensive analysis of the included literature showed that the difference between the tirofiban and non-tirofiban groups in terms of successful recanalization (OR = 1.19, 95% Cl [0.69, 2.03], = 0.53, = 22%) and favorable functional outcome at 3 months (OR = 1.13, 95% Cl [0.81, 1.60], = 0.47, = 17%) in patients with IVT bridging mechanical thrombectomy of AIS was not statistically significant. Also, the differences in the incidence of sICH (OR = 0.97, 95% Cl [0.58, 1.62], = 0.89) and ICH (OR = 0.83, 95% Cl [0.55, 1.24], = 0.36) between the two groups were not statistically significant. However, the use of tirofiban during IVT bridging mechanical thrombectomy reduced the rate of postoperative re-occlusion (OR = 0.36, 95% Cl [0.14, 0.91], = 0.03) and mortality within 3 months (OR = 0.54, 95% Cl [0.33, 0.87], = 0.01) in patients.
CONCLUSION
The use of tirofiban during IVT bridging mechanical thrombectomy for AIS does not increase the risk of sICH and ICH in patients and reduces the risk of postoperative re-occlusion and mortality in patients within 3 months. However, this result needs to be further confirmed by additional large-sample, multicenter, prospective randomized controlled trials.

Review
OBJECTIVES
To assess through literature case analysis how advances in lymphatic imaging, interventional radiology, and lymphatic vascular microsurgery illuminate and improve the lymphatic-flow status in select patients with Noonan syndrome (NS) who have undergone surgical intervention as a part of their comprehensive and individualized treatment plan. Also, we sought to illustrate the spectrum of lymphatic complications that can occur in this patient population when lymphatic flow through abnormal vasculature is surgically disrupted.
METHODS
A literature review was performed by searching "Noonan AND Lymphatic AND Imaging" in the PubMed database. Inclusion criteria for this study were (1) diagnosis and clinical description of at least one original patient with NS, (2) imaging figures depicting lymphatic structure and function or a description of lymphatic imaging findings when a figure is not present, and (3) documentation of either lymphatic surgical intervention or lymphatic complications resulting from other procedures. Patient cases were first grouped by documented surgical intervention type, then clinical outcomes and lymphatic imaging results were compared.
RESULTS
A total of 18 patient cases from 10 eligible publications were included in our review. Lymphatic imaging findings across all patients included lymphatic vessel dysplasia along with flow disruption (n = 16), thoracic duct malformations (n = 12), dermal lymphatic reflux (n = 7), and dilated lymphatic vessels (n = 4). Lymphovenous anastomosis (n = 4) resulted in rapid improvement of patient symptoms and signs. New-onset lymphatic manifestations noted over 10 to 20 years for two of these patients were chylothorax (n = 1), erysipelas (n = 1), and gradual-onset nonchylous scrotal lymphorrhea (n = 1). Targeted endovascular lymphatic disruption via sclerosis, embolization, or ablation (n = 8) results were mixed depending on the degree of central lymphatic involvement and included resolution of symptoms (n = 1), postoperative abdominal hemorrhage (n = 1), stable condition or minor improvement (n = 5), and death (n = 2). Large lymphatic vessel ligation or accidental incision (n = 6) occurred during thoracotomy (n = 4), scrotoplasty (n = 1), or inguinal lymph node biopsy (n = 1). These resulted in postoperative onset of new-onset regional lymphatic reflux (n = 5), chylothorax (n = 4), death (n = 3), or persistent or unchanged symptoms (n = 1).
CONCLUSIONS
Imaging of the central lymphatics enabled characterization of lymphatic developmental features and guided operative management of lymphatic vascular defects in patients with NS. This review of the literature suggests that the surgical preservation or enhancement of central lymphatic return in patients with NS may improve interventional outcomes, whereas the disruption of central lymph flow has significant potential to cause severe postoperative complications and worsening of the patient's clinical condition.

Review
OBJECTIVES
Mortality and morbidity following hepatic resection is significantly affected by major intra-operative blood loss. This systematic review and meta-analysis evaluates whether selective hepatic vascular exclusion (SHVE) compared to a Pringle maneuver in hepatic resection reduces rates of morbidity and mortality.
METHODS
A systematic review and meta-analysis were conducted according to the PRISMA guidelines by screening EMBASE, MEDLINE/PubMed, CENTRAL and SCOPUS for comparative studies meeting the inclusion criteria. Pooled odds ratios or mean differences were calculated for outcomes using either fixed- or random-effects models.
RESULTS
Six studies were identified: three randomised controlled trials and three observational studies reporting a total of 2,238 patients. Data synthesis showed significantly decreased rates of mortality, overall complications, blood loss, transfusion requirements, air embolism, liver failure and multi-organ failure in the SHVE group. Rates of hepatic vein rupture, post-operative hemorrhage, operative and warm ischemia time, length of stay in hospital and intensive care unit were not statistically significant between the two groups.
CONCLUSION
Performing SHVE in major hepatectomy may result in reduced rates of morbidity and mortality when compared to a Pringle maneuver. The results of this meta-analysis are based on studies where tumors were adjacent to major vessels. Further RCTs are required to validate these results.

Meta-Analysis Review
OBJECTIVE
To investigate the clinical impact of coeliac artery (CA) coverage during thoracic endovascular aortic repair (TEVAR).
METHODS
This systematic review and meta-analysis was conducted according to the PRISMA guidelines. Electronic databases were searched from 1989 to 2020 for studies reporting visceral ischaemia, spinal cord ischaemia (SCI), 30 day/in hospital mortality, endoleaks, re-intervention, and caudal stent graft migration following CA coverage in patients undergoing TEVAR. Meta-analysis was conducted using random effects modelling. The quality of the evidence was graded using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach.
RESULTS
Fifteen observational studies with 236 patients (108 male, age range 61.3 - 79 years) were included. The pooled visceral ischaemia rate was 13% with significant heterogeneity between studies (95% confidence intervals [CI] 4 - 24; I = 72%, p < .001). The SCI rate was 5% (95% CI 2 - 9; I = 0%); the 30 day/in hospital mortality was 4% (95% CI 1 - 7; I = 0%); the overall endoleak rate was 21% (95% CI 13 - 29; I = 35%) with a 5% (95% CI 0 - 13; I = 38%) rate of type Ib and 2% (95% CI 0 - 8; I = 43%) rate of type II endoleak from retrograde CA flow. The re-intervention rate was 13% (95% CI 6 - 22; I = 54%); the caudal stent graft migration rate was 3% (95% CI 0 - 9, I = 0%). The certainty of the body of evidence was judged to be very low for all outcomes.
CONCLUSION
CA coverage during TEVAR is associated with high rates of visceral ischaemia, spinal cord ischaemia, 30 day/in hospital mortality, endoleaks, and re-intervention. Although the literature is of poor quality and questions remain over effects estimates, there is evidence that CA coverage should be avoided if at all possible, during TEVAR.
