Meta-Analysis Review
INTRODUCTION
Approximately one third of patients with Acute Type A Aortic Dissection (ATAAD) present with pre-operative malperfusion syndromes (MPS). Of these, mesenteric malperfusion represents the greatest risk to patients with respect to increased short-term mortality. In select patients, it may be feasible to offer a staged approach by treating the mesenteric malperfusion first, optimizing the patient in the intensive care setting and then, following with a central aortic repair. The aim of this systematic review is to summarize cohort studies assessing the role of pre-operative interventions for mesenteric malperfusion.
METHODS
An electronic literature search of five databases was performed to identify all relevant studies providing studies examining short-term mortality on patients who underwent either endovascular or open revascularisation of mesenteric ischemia prior to central aortic repair. The primary outcome was all-cause, short-term mortality. Secondary outcomes were comparative mortality between a delayed repair vs. aortic repair first strategy, rates of postoperative laparotomy, bowel resection, and mortality following delayed aortic repair.
RESULTS
The search strategy identified 8 studies qualifying for inclusion, with a total of 180 patients who underwent delayed aortic surgery in the setting of mesenteric MPS. The weighted short-term mortality following a mesenteric revascularisation first, delayed aortic surgery strategy was 22.5%. This strategy was also associated with a significantly lower mortality than a central repair first strategy (OR 0.07, 95% CI 0.02-0.27), and a significantly lower rate of postoperative laparotomy/bowel resection (OR 0.05, 95% CI 0.02-0.14). If patients survive to receive central repair, the weighted short-term mortality postoperatively is low (2.1%).
CONCLUSION
A summary of this evidence reveals a lower short-term mortality in hemodynamically stable patients with mesenteric malperfusion, along with a reduction in postoperative laparotomy/bowel resections. Of those patients who survive to receive central repair, short-term mortality remains very low in the select group of hemodynamically stable patients. Further high-quality studies with randomized or propensity matched data are required to verify these results.

Review
Despite guideline recommendations, strategies for implementing cardiac rehabilitation (CR) in patients with acute aortic dissection (AAD) are not well established with little evidence to risk stratify prudent and effective guidelines for the many required variables. We conducted a systematic review of studies (2004-2023) reporting CR following type A (TA) and type B (TB) AAD. Our review is limited to open surgical repair for TA and medical treatment for TB. A total of 5 studies were included (4 TA-AAD and 1 TB-AAD) in the qualitative analysis. In general, observational data included 311 patients who had an overall favorable effect of CR in AAD consisting of a modestly improved exercise capacity and work load during cycle cardiopulmonary exercise test (TB-AAD), and improved quality of life (QoL). No adverse events were reported during symptom limited pre-CR treadmill or cycle exercise VO max or CR. Given the overall potential in this high risk population without adequate evidence for important variables such as safe time from post-op to CR, intensity of training, duration and frequency of sessions and followup it is time for a moderate sized well designed safe trial for patients' post-op surgery for TA-AAD and medically treated TB-AAD who are treated with standardized evidence based medical therapy and physical therapy from discharge randomized to CR versus usual care.

Meta-Analysis
Efficacy and safety comparison between axillary lymph node dissection with no axillary surgery in patients with sentinel node-positive breast cancer: a systematic review and meta-analysis.
BACKGROUND
This systematic review and meta-analysis aimed to study the evidence on the efficacy and safety of omitting axillary lymph node dissection (ALND) for patients with clinically node-negative but sentinel lymph node (SLN)-positive breast cancer using all the available evidence.
METHODS
The Embase, Medline, and Cochrane Library databases were searched through February 25, 2023. Original trials that compared only the sentinel lymph node biopsy (SLNB) with ALND as the control group for patients with clinically node-negative but SLN-positive breast cancer were included. The primary outcomes were axillary recurrence rate, total recurrence rate, disease-free survival (DFS), and overall survival (OS). Meta-analyses were performed to compare the odds ratio (OR) in rates and the hazard ratios (HR) in time-to-event outcomes between both interventions. Based on different study designs, tools in the revised Cochrane risk of bias tool were used for randomized trials and the risk of bias in nonrandomized studies of interventions to assess the risk of bias for each included article. Funnel plots and Egger's test were used for the publication's bias assessment.
RESULTS
In total, 30 reports from 26 studies were included in the systematic review (9 reports of RCTs, 21 reports of retrospective cohort studies). According to our analysis, omitting ALND in patients with clinically node-negative but SLN-positive breast cancer had a similar axillary recurrence rate (OR = 0.95, 95% confidence interval (CI): 0.76-1.20), DFS (HR = 1.02, 95% CI: 0.89-1.16), and OS (HR = 0.97, 95% CI: 0.92-1.03), but caused a significantly lower incidence of adverse events and benefited in locoregional recurrence rate (OR = 0.76, 95% CI: 0.59-0.97) compared with ALND.
CONCLUSION
For patients with clinically node-negative but SLN-positive breast cancer (no matter the number of the positive SLN), this review showed that SLNB alone had a similar axillary recurrence rate, DFS, and OS, but caused a significantly lower incidence of adverse events and showed a benefit for the locoregional recurrence compared with ALND. An OS benefit was found in the Macro subset that used SLNB alone versus complete ALND. Therefore, omitting ALND is feasible in this setting.

Review
BACKGROUND
Contemporary management of spontaneous coronary artery dissection (SCAD) is still controversial. This systematic review of the literature aims to explore outcomes in the patients treated with conservative management vs. invasive strategy.
METHODS
The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed when we extensively searched three electronic databases: PubMed, ScienceDirect, and Web of Science, for studies that compared conservative vs. invasive revascularization treatment outcomes for patients with SCAD from 2003 to 2023. The outcomes of interest were all-cause death and major adverse cardiovascular events (MACE), including acute coronary syndrome (ACS), heart failure (HF), need for additional revascularization, target vessel revascularization (TVR), SCAD recurrence, and stroke.
RESULTS
The systematic review included 13 observational studies evaluating 1,801 patients with SCAD. The overall mean age was 49.12 +/- 3.41, and 88% were females. The overall prevalence of arterial hypertension was 33.2%, hyperlipidemia, 26.9%, smoking, 17.8%, and diabetes, 3.9%. Approximately 48.5% of the patients were diagnosed with non-ST elevated myocardial infarction (NSTEMI), 36.8% with ST elevated myocardial infarction (STEMI), 3.41% with unstable angina, 0.56% with stable angina, and 0.11% were diagnosed with various types of arrhythmias. The left anterior descending artery (LAD) was the most common culprit lesion in 51% of the patients. There were initially 65.2% of conservatively treated patients vs. 33.4% that underwent percutaneous coronary intervention (PCI) or 1.28% that underwent coronary artery bypass graft (CABG). SCAD-PCI revascularization was associated with a variable range of PCI failure. The most common complications were hematoma extension and iatrogenic dissection. SCAD-PCI revascularization frequently required three or more stents and had residual areas of dissection. The overall reported in-hospital and follow-up mortality rates were 1.2% and 1.3%, respectively. The follow-up range across studies was 7.3-75.6 months. The authors reported variable prevalence of MACE, recurrent SCAD up to 31%, ACS up to 27.4%, TVR up to 30%, repeat revascularization up to 14.7%, UA up to 13.3%, HF up to 17.4%, and stroke up to 3%.
CONCLUSION
Our results highlight that conservative treatment should be the preferred method of treatment in patients with SCAD. PCI revascularization is associated with a high prevalence of periprocedural complications. SCAD poses a considerable risk of MACE, mainly associated with TVR, ACS, and recurrent SCAD.

Review
The aim of this study was to systematically review the current evidence regarding the oncological and functional outcomes of salvage radical prostatectomy (sRP) for recurrent prostate cancer. A systematic review was conducted throughout September 2022 using the PubMed, Science Direct, Scopus, and Embase databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. A total of 55 studies (3836 patients) met our eligibility criteria. The vast majority of men included had radiation therapy (including brachytherapy) as their first-line treatment ( = 3240, 84%). Other first-line treatments included HIFU ( = 338, 9%), electroporation ( = 59, 2%), proton beam therapy ( = 54, 1.5%), cryotherapy ( = 34, 1%), focal vascular targeted photodynamic therapy ( = 22, 0.6%), and transurethral ultrasound ablation ( = 19, 0.5%). Median preoperative PSA, at the time of recurrence, ranged from 1.5 to 14.4 ng/mL. The surgical approach was open in 2300 (60%) cases, robotic in 1465 (38%) cases, and laparoscopic in 71 (2%) cases. Since 2019, there has been a clear increase in robotic versus conventional surgery (1245 versus 525 cases, respectively). The median operative time and blood loss ranged from 80 to 297 min and 75 to 914 mL, respectively. Concomitant lymph node dissection was performed in 2587 cases (79%). The overall complication rate was 34%, with a majority of Clavien grade I or II complications. Clavien ≥ 3 complications ranged from 0 to 64%. Positive surgical margins were noted in 792 cases (32%). The median follow-up ranged from 4.6 to 94 months. Biochemical recurrence after sRP ranged from 8% to 51.5% at 12 months, from 0% to 66% at 22 months, and from 48% to 59% at 60 months. The specific and overall survival rates ranged from 13.4 to 98% and 62 to 100% at 5 years, respectively. Urinary continence was maintained in 52.1% of cases. sRP demonstrated acceptable oncological outcomes. These results, after sRP, are influenced by several factors, and above all by pre-treatment assessment, including imaging, with the development of mpMRI and metabolic imaging. Our results demonstrated that SRP can be considered a suitable treatment option for selected patients, but the level of evidence remains low.

Review
The advantages of endoscopic submucosal dissection (ESD) over endoscopic mucosal resection for large colorectal neoplasms are well established; however, the technical challenges and lack of adequate training in ESD limit its widespread adoption in Western countries. A literature search was performed in Medline, Embase, Web of Science, and the Cochrane Library for studies conducted in non-Asian countries evaluating the effectiveness of colorectal ESD. A random effects model was used to obtain pooled en bloc, R0 resection rates, and adverse events (AEs). Thirty-three studies comprising 3,958 ESD procedures met the inclusion criteria. Of the polyps, 96.7% (2,817 of 2913) were ≥ 2 cm. Pooled en bloc resection (31 studies), R0 resection (29 studies), and curative resection rates were 84.6% (95% confidence interval [CI] [83.3%-85.9%]), 75.6% (95% CI [74.1%-77.0%]), and 81.9% (95% CI [78.6%-84.9%]), respectively. Surgery for invasive cancer was performed in 4.8% (23 studies). ESD-related perforation (25 studies) was observed in 5.5% and bleeding in 4.1% (delayed bleeding 3.4%). 1.8% of patients underwent surgery for procedure-related complications. A high degree of heterogeneity was observed for en bloc resection, R0 resection, and curative resection. Heterogeneity for AEs (perforation [I 13%], delayed bleeding [I 30%], and overall bleeding [I 49%]) was low to moderate. The effectiveness of colorectal ESD for large colorectal polyps and early colorectal cancers is improving in Western countries, and recent resection rates are comparable to that seen in Asia. Colorectal perforation is still observed in about 5% of ESD; however, < 2% of patients need emergency surgery for AEs.

OBJECTIVE
The management of cervical artery dissections (CADs) is poorly standardized given the scarce number of prospective studies comparing medical and interventional approach to CAD. The aim of the present study is to perform a systematic review and meta-analysis of studies on the treatments of CAD.
METHODS
Systematic review and meta-analysis (pre-registered on PROSPERO [CRD42022297512] are performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses [PRISMA] guidelines searching in three different databases [PubMed, Embase and Cochrane Database]) of studies on medical or interventional approach to CAD. Only prospective studies were selected to reduce the risk of bias for the primary meta-analysis. Secondarily, retrospective studies were also included. The aim was to assess the rate of stroke and of stroke/death/bleeding (major or intracranial) by Der Simonian-Laird weights of random effects model.
RESULTS
After screening 456 articles, 6 prospective and 22 retrospective studies were identified. Two randomized controlled trials and five retrospective studies comparing antiplatelet (APT) vs oral anticoagulant therapy (OAC) for CAD were identified, as well as four prospective and 17 retrospective single-arm studies evaluating stenting for CAD. In the meta-analysis of randomized controlled trials comparing APT vs OAC, 444 patients were considered, and a borderline significant association was identified in terms of stroke/death in the APT vs OAC groups (odds ratio [OR], 5.6; 95% confidence interval [CI], 0.94-33.38; P = .06; I = 0%). No differences were found for the stroke/death/bleeding outcome (OR, 1.25; 95% CI, 0.19-8.18; P = .81; I = 0%) between the two treatments. In the meta-analysis including also retrospective studies, overall risk of bias was considered "serious," and 4104 patients were included with no differences in APT vs OAC for stroke (OR, 1.06; 95% CI, 0.53-2.11; P = .29; I = 18%); no other comparisons were possible. The pooled meta-analysis of prospective studies on stenting for CAD included four series, for a total of 68 patients, in whom stenting was adopted primarily after failed medical therapy or after traumatic dissection. The pooled rate of stroke/death was 7% (95% CI, 3%-17%; I = 0%). The analysis of moderators identified a significant inverse association between the percentage of traumatic dissection and a reduction in postoperative stroke (Y = -1.60-2.02X; P = .03). The pooled rate of the composite endpoint of stroke/death/ or major bleeding was 8% (95% CI, 3%-18%; I = 0%). Secondarily, the meta-analysis also included 17 retrospective studies with overall 457 patients and showed a 2.1% pooled rate of stroke/death (95% CI, 1.0%-3.3%; I = 0%) and 3.2% stroke/death/bleeding (95% CI, 1.8%-4.7%; I = 0%).
CONCLUSIONS
Few prospective studies on CAD treatment are present in literature. APT and OAC seem to have similar efficacy in reducing the recurrence of stroke after CAD. No definitive conclusion can be drawn for stenting, due to the low number of studies available. More prospective studies are necessary to evaluate its potential additional value over medical therapy alone in the early phase after CAD.

Review
OBJECTIVE
This study aimed to conduct a meta-analysis evaluating the optimal timing for endovascular repair of acute versus subacute uncomplicated Type B Aortic Dissection.
METHOD
PubMed, EMBASE, web of science and Cochrane Library was interrogated to identify Electronic bibliographic studies updated to January 2023 to collect studies compared the clinical outcomes of endovascular repair for Acute Versus Subacute Uncomplicated Type B Aortic Dissection. Data were aggregated as pooled odds ratios (OR) using the fixed or random effects models according to the significance of heterogeneity, Pooled odds ratios (OR) were calculated by RevMan 5.3 and applied with fixed or random-effect models.
RESULT
A comprehensive literature search found 322 citations published and finally among them 6 studies containing 3,769 patients (acute group 2,642, subacute group 1,127) were included in review. There is an increased risk of 30-day complications (OR = 1.51,95%CI,1.26-1.81) 30-day mortality (OR = 2.39,95%CI, 1.55-3.67) and 1-year mortality (OR = 1.71,95%CI,1.27-2.30) for an acute uTBAD group compared to subacute ones. Similarly, reintervention was more likely in the acute group than in the subacute group (OR = 1.42,95%CI,1.05-1.91). However, no significant differences were found in long-term mortality.
CONCLUSION
This meta-analysis confirmed that there was no significant difference in the long-term prognosis between the acute and subacute phases in the timing of surgery. However, considering the high incidence of complications, high re-intervention rate and one-year mortality probably caused by high intima fragility in the acute phase, endovascular repair at subacute phase appears to favorably compare with acute strategy. But future studies with adequate patient numbers and longer-term follow-up are necessary to further verify the study conclusion.

Meta-Analysis
The incidence of perioperative lymphatic complications after radical hysterectomy and pelvic lymphadenectomy between robotic and laparoscopic approach : a systemic review and meta-analysis.
BACKGROUND
Although many studies have reported perioperative complications after radical hysterectomy and pelvic lymph node dissection using robotic and laparoscopic approaches, the risk of perioperative lymphatic complications has not been well identified. The aim of this meta-analysis is to compare the risks of perioperative lymphatic complications after robotic radical hysterectomy and lymph node dissection (RRHND) with laparoscopic radical hysterectomy and lymph node dissection (LRHND) for early uterine cervical cancer.
MATERIALS AND METHODS
The authors searched the PubMed, Cochrane Library, Web of Science, ScienceDirect, and Google Scholar databases for studies published up to July 2022 comparing perioperative lymphatic complications after RRHND and LRHND while treating early uterine cervical cancer. Related articles and bibliographies of relevant studies were also checked. Two reviewers independently performed the data extraction.
RESULTS
A total of 19 eligible clinical trials (15 retrospective studies and 4 prospective studies) comprising 3079 patients were included in this analysis. Only 107 patients (3.48%) had perioperative lymphatic complications, of which the most common was lymphedema ( n =57, 1.85%), followed by symptomatic lymphocele ( n =30, 0.97%), and lymphorrhea ( n =15, 0.49%). When all studies were pooled, the odds ratio for the risk of any lymphatic complication after RRHND compared with LRHND was 1.27 (95% CI: 0.86-1.89; P =0.230). In the subgroup analysis, study quality, country of research, and publication year were not associated with perioperative lymphatic complications.
CONCLUSIONS
A meta-analysis of the available current literature suggests that RRHND is not superior to LRHND in terms of perioperative lymphatic complications.

The ring finger protein 213 gene (RNF213) is involved in several vascular diseases, both intracranial and systemic ones. Some variants are common in the Asian population and are reported as a risk factor for moyamoya disease, intracranial stenosis and intracranial aneurysms. Among intracranial vascular diseases, both moyamoya disease and intracranial artery dissection are more prevalent in the Asian population. We performed a systematic review of the literature, aiming to assess the rate of RNF213 variants in patients with spontaneous intracranial dissections. Four papers were identified, providing data on 53 patients with intracranial artery dissection. The rate of RNF213 variants is 10/53 (18.9%) and it increases to 10/29 (34.5%), excluding patients with vertebral artery dissection. All patients had the RNF213 p.Arg4810Lys variant. RNF213 variants seems to be involved in intracranial dissections in Asian cohorts. The small number of patients, the inclusion of only patients of Asian descent and the small but non-negligible coexistence with moyamoya disease familiarity might be limiting factors, requiring further studies to confirm these preliminary findings and the embryological interpretation.
