RESUMEN

Background: Antiplatelet therapy plays an important role in reducing the risk of stroke recurrence in patients with mild ischemic stroke or high-risk transient ischemic attack (TIA). However, data regarding the effectiveness and safety of using aspirin plus clopidogrel in dual antiplatelet therapy (DAPT) compared to aspirin alone in mild ischemic stroke is limited. Methods: PubMed/MEDLINE, Embase, Cochrane Library, and ClinicalTrials.gov were searched for randomized controlled trials (RCTs) that compared DAPT to aspirin alone started within 72 hours in mild ischemic stroke or high-risk TIA. We used a random effects model to pool risk ratios (RRs) along with 95% CIs for clinical outcomes. Results: Four RCTs with 16,547 patients were included in this study. DAPT significantly reduced the risk of recurrent stroke by 26% (RR: 0.74; 95% CI: 0.67-0.83; p < 0.00001), ischemic stroke by 28% (RR: 0.72; 95% CI: 0.65-0.80; p < 0.00001), and major adverse cardiovascular events (MACE) by 24% (RR: 0.76; 95% CI: 0.68-0.84; p < 0.00001) compared to aspirin monotherapy. However, DAPT was associated with a significantly increased risk of moderate or severe bleeding (RR: 1.88; 95% CI: 1.10-3.23; p = 0.02) compared to aspirin alone. No significant differences were observed for hemorrhagic stroke (RR: 1.77; 95% CI: 0.96-3.29; p = 0.07), all-cause mortality (RR: 1.25; 95% CI: 0.87-1.80; p = 0.23), cardiovascular mortality (RR: 1.38; 95% CI: 0.81-2.33; p = 0.23), and myocardial infarction (RR: 1.63; 95% CI: 0.77-3.46; p = 0.20). Conclusion: DAPT involving aspirin plus clopidogrel reduces stroke recurrence and MACE but can lead to an increased risk of moderate or severe bleeding compared to aspirin monotherapy.

RESUMEN

PURPOSE: Lumbar degenerative diseases impose a substantial health burden, prompting the exploration of advanced surgical approaches such as Oblique Lumbar Interbody Fusion (OLIF). This meta-analysis aims to evaluate the comparative efficacy of OLIF with anterior screw fixation (OLIF-AF) against OLIF with posterior pedicle fixation (OLIF-PF) in addressing these conditions. METHODS: A systematic search across multiple databases identified five studies meeting inclusion criteria, incorporating a total of 271 patients. Comparative analysis encompasses primary and secondary outcomes related to fusion rates, intraoperative parameters, patient-reported measures, and radiographic assessments. RESULTS: Primary outcome analysis demonstrated no statistically significant difference in total fusion rates between OLIF-AF and OLIF-PF. However, secondary outcomes revealed distinct advantages in OLIF-AF, showcasing lower intraoperative blood loss and reduced operative times compared to OLIF-PF. Nonetheless, patient-reported outcomes, encompassing measures such as pain scores and functional assessments, as well as radiographic parameters, exhibited no significant variations between the two techniques. CONCLUSION: While OLIF-AF displayed favorable results in intraoperative parameters, such as reduced blood loss and shorter operative times, it did not significantly differ in patient-reported outcomes and radiographic assessments compared to OLIF-PF. Interpretation of findings must consider limitations in sample sizes and study heterogeneity. Future investigations with larger, more diverse cohorts and extended follow-ups are imperative to confirm these preliminary findings and comprehend the actual clinical impact of these OLIF techniques in managing lumbar degenerative diseas.

RESUMEN

This meta-analysis aimed to assess the outcomes of patients with atrial fibrillation undergoing chronic hemodialysis, comparing the effectiveness of direct oral anticoagulants (DOACs) and vitamin K antagonists. A systematic search was conducted across various databases including PubMed, Embase, and Google Scholar. Efficacy outcomes focused on the risk of stroke and mortality, whereas safety outcomes assessed the risk of bleeding. Review Manager generated forest plots for data synthesis. Statistical significance was set at P < 0.05, and random-effects models were used. Subgroup analysis identified the sources of heterogeneity. Nine studies met the inclusion criteria for the final analysis. The risk of all-cause stroke [risk ratio (RR): 0.64; 95% confidence interval (CI): 0.51-0.81; P = 0.0001; I2 = 0%], ischemic stroke (RR: 0.53; 95% CI: 0.29-0.96; P = 0.04; I2 = 0%), all-cause mortality (RR: 0.73; 95% CI: 0.60-0.88; P = 0.001; I2 = 71%), major bleeding (RR: 0.63; 95% CI: 0.52-0.76; P < 0.00001; I2 = 44%), gastrointestinal bleeding (RR: 0.67; 95% CI: 0.53-0.85; P = 0.0009; I2 = 36%), intracranial hemorrhage (RR: 0.57; 95% CI: 0.38-0.84; P = 0.004; I2 = 0%) were lower in the DOAC group compared with the vitamin K antagonist group. The risk of cardiovascular-related death (RR: 1.34; 95% CI: 0.69-2.60; P = 0.39; I2 = 0%), clinically relevant nonmajor bleeding (RR: 0.90; 95% CI: 0.75-1.08; P = 0.26; I2 = 28%), and hemorrhagic stroke (RR: 0.36; 95% CI: 0.06-2.24; P = 0.28; I2 = 10%) showed no significant differences. In conclusion, the risks of all-cause stroke, ischemic stroke, all-cause mortality, major bleeding, gastrointestinal bleeding, and intracranial hemorrhage in patients with atrial fibrillation undergoing chronic hemodialysis were lower in the DOAC group.

RESUMEN

INTRODUCTION: Cerebral Embolic Protection Device (CEPD) captures emboli during Transcatheter Aortic Valve Replacement (TAVR). With recently published pivotal trials and multiple cohort studies reporting new data, there is a need to re-calibrate available statistical evidence. METHODS: A systematic literature search was conducted across databases from inception till February 2023. Dichotomous outcomes were pooled using Odds Ratio (OR), while continuous outcomes were pooled using Standardized Mean Difference (SMD) along with 95% corresponding intervals (95% CIs). RESULTS: Data was included from 17 studies (7 RCTs, 10 cohorts, n = 155,829). Use of CEPD was associated with significantly reduced odds of stroke (OR = 0.60, 95% CI = 0.43-0.85, p = 0.003). There was no significant difference in disabling stroke (p = 0.25), non-disabling stroke (p = 0.72), and 30-day mortality (p = 0.10) between the two groups. There were no significant differences between the two groups for Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI) findings, acute kidney injury, risk of pacemaker implantation life-threatening bleed, major bleed, minor bleed, worsening National Institute of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS) and vascular complications (p > 0.05). CONCLUSIONS: The use of CEPD during TAVR reduced the incidence of all-stroke (p = 0.003); however, there were no significant differences in any of the other pooled outcomes (p > 0.05). REGISTRATION: The protocol of this meta-analysis was registered with the Open Science framework [https://doi.org/10.17605/OSF.IO/7W564] before data acquisition was started.

RESUMEN

This systematic review will provide a comprehensive assessment of the evidence on PICSO in STEMI patients, and it will help to determine the role of this novel technique in the management of STEMI. The review searched for the relevant articles in the PubMed, Embase, Cochrane Library, and Web of Science databases regarding PC-ICSO. Four cohort studies were eligible to be included in the quantitative analysis. In the pooled analysis, the use of PICSO was associated with a significant reduction in infarct size (SMD = -0.44, 95% CI = -0.76,-0.13, p = 0.004). PICSO administration was associated with a reduced risk of developing microvascular resistance (RR = 0.75, 95% CI = 0.62,0.92, p = 0.0051). The post-procedural Index of Microvascular Occlusion (MVO) was lower in the PICSO treated compared to the control group and this result was homogenous and statistically significant (SMD = -0.35, 95% CI = -0.68-0.01, p = 0.03, I2 = 0%). Compared to matched controls, the use of PICSO was associated with higher Left Ventricular Ejection Fraction (LVEF) at the longest follow-up (SMD = 0.328, 95% CI = 0.03, 0.06, p = 0.03, I2 = 0%). This review suggested that PICSO can be used during PPCI in STEMI with improved outcomes of infarct size, LVEF, and microvascular perfusion.

RESUMEN

OBJECTIVE: This systematic review and meta-analysis aims to evaluate the efficacy and safety of bevacizumab in patients with ovarian cancer over a shorter and longer follow-up period. METHODS: We searched Medline, Cochrane CENTRAL, Scopus, and Google Scholar for all phase 3 randomized controlled trials (RCTs) that administered bevacizumab to women with ovarian cancer. Review Manager 5.4 was used to calculate risk ratios (RR) and hazard ratios (HR) with 95% CIs. We assessed the quality of the included studies using version 2 of the Cochrane Risk of Bias tool (RoB 2). RESULTS: After screening the titles, abstracts, and full texts, we included nine RCTs in our systematic review and meta-analysis. Four RCTs had a low risk of bias, while 5 had some concerns. Bevacizumab was associated with a progression free survival benefit for <36 months (HR: 0.59, 95% CI: 0.45-0.76, P <0.0001, I2 =90%) and >36 months (HR: 0.66, 95% CI: 0.55-0.80, P <0.0001, I2 =80%), and an overall survival benefit for <36 months (HR: 0.87, 95% CI: 0.78-0.98, P =0.02, I2 =0%) but not for >36 months (HR: 0.98, 95% CI: 0.89-1.09, P =0.77, I2 =30%). There was no difference in deaths between intervention and control groups <36 months (RR: 0.95, 95% CI: 0.86-1.04, P =0.26, I2 =10%) or >36 months (RR: 1.02, 95% CI: 0.97-1.06, P =0.50, I2 =0%). Bevacizumab reduced disease progression <36 months (RR: 0.82, 95% CI: 0.72-0.92, P =0.0008, I2 =82%) but not at >36 months (RR: 0.83, 95% CI: 0.58-1.19, P =0.30, I2 =94%). The adverse events reported with Bevacizumab use included thrombocytopenia, neutropenia, leukocytopenia, anemia, hypertension, bleeding or hemorrhage, and gastrointestinal, cardiac, and dermatological adverse events. CONCLUSION: Bevacizumab may improve progression-free survival within and after 36 months, overall survival within 36 months, and reduce disease progression within 36 months.

RESUMEN

Traditionally, left-sided upper extremity (LUE) access has been preferred in patients undergoing endovascular aortic repair (EVAR) to manage aortic aneurysms and decrease the risk of cerebrovascular adverse events. Recently, right-sided upper extremity access (RUE) has gained popularity owing to its greater maneuverability and ergonomics. However, synthesized data comparing the safety and efficacy of RUE and LUE accesses are limited. A comprehensive literature search was conducted on various databases from inception to September 2023 to retrieve all studies that compared RUE and LUE access in EVAR. Data on stroke, 30-day mortality, technical success, access-site complications, total time required for fluoroscopy, and contrast agent requirement were extracted, pooled, and analyzed. Forest plots were generated using a random-effects model on review manager by pooling the risk ratios (RRs) and standard mean differences (SMDs). Ten observational studies with a total of 3994 patients were included in our analysis with 1186 patients in the RUE and 2808 patients in the LUE access groups. EVAR using RUE access was associated with a significantly lower amount of contrast agent requirement than the LUE access group [SMD, -0.23; 95% confidence interval (CI), -0.45 to -0.02; P = 0.03]. There was no significant difference between the 2 groups in terms of the risk of stroke (RR, 1.62; 95% CI, 0.81-3.22; P = 0.17), 30-day mortality (RR, 1.42; 95% CI, 0.50-4.06; P = 0.51), rate of technical success (RR, 0.98; 95% CI, 0.95-1.01; P = 0.18), risk of access-site complications (RR, 1.00; 95% CI, 0.72-1.39; P = 0.99), and total time required for fluoroscopy (SMD, 0.07; 95% CI, -0.39 to 0.26; P = 0.69). The use of RUE access in EVAR appears to be comparable to LUE access in terms of the risk of stroke, access-related complications, all-cause mortality, technical success rate, and fluoroscopy duration. The RUE group required a lower volume of contrast agent.

RESUMEN

BACKGROUND: Acute decompensated heart failure (ADHF) presents a significant global health challenge, with high morbidity, mortality, and healthcare costs. The current therapeutic options for ADHF are limited. Ivabradine, a selective inhibitor of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, has emerged as a potential therapy for ADHF by reducing the heart rate (HR) without negatively affecting myocardial contractility. However, the evidence regarding the efficacy and safety of ivabradine in patients with ADHF is limited and inconsistent. This meta-analysis aimed to evaluate the efficacy and safety of ivabradine for ADHF based on observational studies. METHODS: A systematic literature search was conducted following PRISMA guidelines to identify relevant observational studies comparing ivabradine with placebo in adult patients with ADHF. Data were pooled using a random-effects model, and heterogeneity was assessed. The risk of bias was evaluated using the Newcastle-Ottawa Scale. RESULTS: Four observational studies comprising a total of 12034 patients. Meta-analysis revealed that ivabradine significantly reduced all-cause mortality (RR: 0.66, 95 % CI: 0.49-0.89, p < 0.01) and resting HR (MD: -12.54, 95 % CI: -21.66-3.42, p < 0.01) compared to placebo. However, no significant differences were observed in cardiovascular mortality, hospital readmission for all causes, changes in LVEF, or changes in LVEDD. Sensitivity and publication bias assessments were conducted for each outcome. CONCLUSION: Ivabradine may be beneficial for reducing mortality and HR in patients with ADHF. However, its impact on other clinical outcomes such as cardiovascular mortality, hospital readmission, and cardiac function remains inconclusive. Further research, particularly well-designed RCTs with larger sample sizes and longer follow-up durations, are warranted.

RESUMEN

Both types of aortic dissection (AD), Stanford type A and type B, can result in complications such as acute kidney injury (AKI) and aortic rupture. Renal complications in AD arise from compromised renal perfusion affecting the renal arteries. Understanding the intricate connection between AD and AKI is crucial for navigating the complexities of tailored treatment and formulating specific management plans. Concerning machine learning models, in patients with type A aortic dissection, factors such as decreased platelet count on admission, increased D-dimer level, longer cardiopulmonary bypass duration, elevated white blood cell levels, the need for blood transfusion, longer aortic clamp time, extended surgery duration, advanced age, and an elevated body mass index were positively associated with the development of AKI. For the risk of AKI after type B aortic dissection, elevated Nt-pro brain natriuretic peptide, prolonged activated partial thromboplastin time, elevated admission systolic blood pressure, and a higher contrast agent requirement during operative repair were found to predict the risk. Male gender was associated with a higher risk of AKI, and nonwhite race was linked to a higher risk of AKI, a greater likelihood of requiring more urgent procedures, and lower levels of insurance coverage. The treatment of AKI following AD requires a multifaceted approach. Identifying and addressing the underlying cause, such as low blood pressure, renal artery involvement, or medication-induced injury, is crucial for effective management and preventing further kidney damage. Maintaining proper fluid balance is essential for improving renal perfusion, but careful monitoring is necessary to avoid complications. The evolving landscape of research, particularly in biomarkers and AI programs, reveals a promising role in predicting the risk for and managing AKI post-AD.

RESUMEN

Endovascular aortic repair is an emerging novel intervention for the management of abdominal aortic aneurysms. It is crucial to compare the effectiveness of different access sites, such as transfemoral access (TFA) and upper extremity access (UEA). An electronic literature search was conducted using PubMed, EMBASE, and Google Scholar databases. The primary endpoint was the incidence of stroke/transient ischemic attack (TIA), while the secondary endpoints included technical success, access-site complications, mortality, myocardial infarction (MI), spinal cord ischemia, among others. Forest plots were constructed for the pooled analysis of data using the random-effects model in Review Manager, version 5.4. Statistical significance was set at p < 0.05. Our findings in 9403 study participants (6228 in the TFA group and 3175 in the UEA group) indicate that TFA is associated with a lower risk of stroke/TIA [RR: 0.55; 95% CI: 0.40-0.75; p = 0.0002], MI [RR: 0.51; 95% CI: 0.38-0.69; p < 0.0001], spinal cord ischemia [RR: 0.41; 95% CI: 0.32-0.53, p < 0.00001], and shortens fluoroscopy time [SMD: -0.62; 95% CI: -1.00 to -0.24; p = 0.001]. Moreover, TFA required less contrast agent [SMD: -0.33; 95% CI: -0.61 to -0.06; p = 0.02], contributing to its appeal. However, no significant differences emerged in technical success [p = 0.23], 30-day mortality [p = 0.48], ICU stay duration [p = 0.09], or overall hospital stay length [p = 0.22]. Patients with TFA had a lower risk of stroke, MI, and spinal cord ischemia, shorter fluoroscopy time, and lower use of contrast agents. Future large-scale randomized controlled trials are warranted to confirm and strengthen these findings.

RESUMEN

Cardiovascular diseases, particularly myocardial infarction (MI), are a significant cause of mortality globally. Traditional MIs are commonly linked to substantial coronary artery blockage. However, a distinct subset of patients experience MI with non-obstructive coronary arteries, known as MINOCA. Imaging techniques, such as invasive coronary angiograms, are employed to diagnose MI or assess predisposition to one. Coronary angiograms help visualize vessel blockages; however, these blockages are absent in MINOCA cases, posing a diagnostic challenge. Precision medicine aims to introduce new diagnostic tools to assist in early diagnosis and further management of MINOCA. As percutaneous coronary intervention (PCI) does not benefit MINOCA patients, medical management tailored to the specific pathophysiological mechanism of MINOCA is employed. For example, if MINOCA is attributed to plaque disruption with or without plaque thrombus formation, the fundamental treatments may include statins, agents that modulate the renin-angiotensin system (RAS), and antiplatelet therapies. On the other hand, if coronary artery spasm is identified as the primary cause, essential intervention involves the use of calcium channel blockers. This approach has been previously utilized in patients with vasospastic angina and could be utilized in MINOCA, although research specific to MINOCA is ongoing. Therefore, the handling of MINOCA underscores the necessity for a tailored therapeutic strategy that corresponds to the underlying physiological mechanism responsible for the patient's clinical symptoms. Ongoing research initiatives are directed at expanding the availability of these treatments, uncovering new biomarkers, creating advanced diagnostic instruments, and establishing a more individualized approach for managing MINOCA patients.

RESUMEN

BACKGROUND: This meta-analysis compares His-Purkinje system pacing (HPSP), a novel cardiac resynchronization therapy (CRT) technique that targets the intrinsic conduction system of the heart, with conventional biventricular pacing (BiVP) in heart failure (HF) patients with left ventricular (LV) dysfunction and dyssynchrony. METHODS: We searched multiple databases up to May 2023 and identified 18 studies (five randomized controlled trials and 13 observational studies) involving 1291 patients. The outcome measures were QRS duration, left ventricular ejection fraction (LVEF) improvement, left ventricular end-diastolic diameter (LVEDD) change, HF hospitalization, and New York Heart Association (NYHA) functional class improvement. We used a random-effects model to calculate odds ratios (OR), and mean differences (MD) with 95% confidence intervals (CI). We also assessed the methodological quality of the studies. RESULTS: The mean LVEF was 30.7% and the mean follow-up duration was 8.1 months. Among LBBP, HBP, and BiVP, HBP provided the shortest QRS duration [MD: -18.84 ms, 95% CI: -28.74 to -8.94; p = 0.0002], while LBBP showed the greatest improvement in LVEF [MD: 5.74, 95% CI: 2.74 to 7.46; p < 0.0001], LVEDD [MD: -5.55 mm, 95% CI: -7.51 to -3.59; p < 0.00001], and NYHA functional class [MD: -0.58, 95% CI: -0.80 to --0.35; p < 0.00001]. However, there was no significant difference in HF hospitalization between HPSP and BiVP. CONCLUSION: LBBP as modality of HPSP demonstrated superior outcomes in achieving electrical ventricular synchrony and systolic function, as well as alleviating HF symptoms, compared to other pacing techniques.

RESUMEN

INTRODUCTION: Chronic total occlusion (CTO) is defined as a near-total blockage of a coronary artery and often occurs in arteries that are not directly responsible for the event, known as non-infarct-related arteries (NIRA). Cardiogenic shock (CS) is a complication of ST-elevated myocardial infarction (STEMI) that carries significant mortality. We performed a meta-analysis to find an association between mortality in patients undergoing PCI for STEMI that have superimposed CS, with the presence of CTO in the NIRA. MATERIALS AND METHODOLOGY: A comprehensive literature search was conducted using PubMed, EMBASE, Google Scholar and clinicaltrials.gov from inception till October 2023 to retrieve studies that compare the presence of CTO with the absence of CTO in NIRA in STEMI with CS patients undergoing PCI. The primary endpoint was 30-day mortality and the secondary endpoints were risk of all-cause mortality (ACM) and repeat myocardial infarction (MI). Forest plots were generated using the random effects model by pooling odds ratios (ORs) with a 95 % confidence interval. Statistical significance was set at p < 0.05. RESULTS: 5 observational studies with a total of 5186 patients (1031 with CTO in NIRA and 4155 with no CTO in NIRA) were included. The presence of CTO in NIRA was associated with higher odds of 30-day mortality [OR: 3.10; 95 % CI: 1.52, 6.32; p < 0.002], and ACM [OR: 2.37; 95 % CI: 1.83, 3.08; p < 0.00001]. The odds of repeat MI were comparable between the two groups [OR: 1.61, 95 % CI: 0.03, 74.36, p = 0.81]. CONCLUSIONS: The presence of CTO in the NIRA serves as an independent indicator of unfavorable clinical outcomes including increased risk of 30-day mortality and all-cause mortality. The risk of repeat MI was comparable between the two groups. Large-scale, multicenter trials are warranted to identify the most effective management approach for these patients.

RESUMEN

Gut microbiota, which comprises a broad range of bacteria inhabiting the human intestines, plays a crucial role in establishing a mutually beneficial relationship with the host body. Dysbiosis refers to the perturbations in the composition or functioning of the microbial community, which can result in a shift from a balanced microbiota to an impaired state. This alteration has the potential to contribute to the development of chronic systemic inflammation. Heart failure (HF) is a largely prevalent clinical condition that has been demonstrated to have variations in the gut microbiome, indicating a potential active involvement in the pathogenesis and advancement of the disease. The exploration of the complex interplay between the gut microbiome and HF presents a potential avenue for the discovery of innovative biomarkers, preventive measures, and therapeutic targets. This review aims to investigate the impact of gut bacteria on HF.

RESUMEN

Coronary stent infection is a rare yet serious complication of coronary artery stenting, with potentially significant morbidity and mortality. This systematic review aimed to comprehensively assess the available evidence on the diagnosis, management, and outcomes of coronary stent infection. A comprehensive search of electronic databases, including PubMed, Embase, Cochrane Library, and Scopus, was conducted from inception until March 2023, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 1 case series and 41 case reports, covering a cumulative sample size of 44 patients, were included in the analysis. The predominant stent types were drug-eluting stents in 22 studies, bare-metal stents in 3 studies, and a combination of drug-eluting stents and bare-metal stents in 4 studies. Staphylococcus aureus was the predominant identified organism in microbiological profiles. Primary outcomes, including mortality, morbidity, and recurrence rates, were evaluated. The aggregate mortality rate across studies was 18%, underscoring the severity of coronary stent infections. Morbidity ranged from 3% to 60%, with a spectrum of complications such as sepsis, heart failure, and embolic events. Recurrence rates varied from 3% to 33%, emphasizing the importance of effective management. Treatment strategies encompassed antibiotics alone, antibiotics with stent removal, and antibiotics with stent retention, with the duration of antibiotic therapy ranging from 2 weeks to 12 months. The optimal management strategy remains uncertain due to limited high-quality evidence. Early diagnosis and treatment were emphasized as critical factors in improving outcomes. Prophylactic antibiotics during stenting procedures and increased awareness among healthcare providers were suggested as preventive measures.

RESUMEN

BACKGROUND: Despite its profound impact on the oncologic outcomes of rectal cancer, the most optimal surgical approach to total mesorectal excision (TME) has not been identified yet. All previous meta-analyses on this subject have been based on observational studies. This meta-analysis was conducted to assess the surgical and oncologic outcomes of laparoscopic TME (LaTME) compared to trans-anal TME (TaTME), utilizing only randomized controlled trials. DESIGN: Systematic review and meta-analysis of randomized controlled trials. METHODS: We searched electronic databases (MEDLINE, Cochrane CENTRAL, Clinicaltials.gov) from 2010 onwards, for all published clinical trials comparing TaTME to LaTME. Results are presented as risk ratios, with 95% CI, and pooled using the random effects model. RESULTS: A total of 1691 patients, from 6 eligible randomized controlled trials, were included for analysis. Analyzed data showed no significant difference in morbidity (RR: 0.85, p = 0.15), mortality (RR: 0.50, p = 0.44), conversion to open (RR: 0.40, p = 0.07), or anastomotic leakage (RR: 0.73, p = 0.10) between TaTME and LaTME. There was also no difference in the rate of positive distal resection margin (DRM) (RR: 0.55, p = 0.10) or positive circumferential resection margin (CRM) (RR: 0.67, p = 0.30). Patients undergoing TaTME were more likely to have a complete TME (RR: 1.06, p = 0.002) and shorter hospital stays (RR: - 0.97, p < 0.00001). CONCLUSIONS: Patients undergoing TaTME for rectal cancer were more likely to have a complete TME when compared to LaTME, though this did not translate into improved distal or circumferential resection margin. Additionally, TaTME and LaTME had similar surgical outcomes except for shorter length of stay with TaTME.
