Preoperative electroacupuncture versus sham electroacupuncture for the treatment of postoperative ileus after laparoscopic surgery for colorectal cancer in China: a study protocol for a multicentre, randomised, sham-controlled trial.

INTRODUCTION: Postoperative ileus (POI) is a postoperative complication that can cause lingering recovery after colorectal resection and a heavy healthcare system burden. Acupuncture aims to prevent postoperative complications, reduce the duration of POI, help recovery and shorten hospital stays. We hypothesise that preoperative electroacupuncture (EA) can promote POI recovery under the enhanced recovery after surgery protocol after laparoscopic surgery in patients with POI. METHODS AND ANALYSIS: This is a multicentre, randomised, sham-controlled trial. A total of 80 patients will be enrolled and randomly assigned to the EA or sham electroacupuncture (SA) group. The eligible patients will receive EA or SA for one session per day with treatment frequency starting on preoperative day 1 for four consecutive days. The primary outcome is the time to first defecation. The secondary outcomes include the time to first flatus, length of postoperative hospital stay, time to tolerability of semiliquid and solid food, postoperative nausea, vomiting, pain and extent of abdominal distention, time to first ambulation, preoperative anxiety, 30-day readmission rate, the usage of anaesthetics and analgesics during operation, length of postanaesthesia care unit stay. A mechanistic study by single-cell RNA sequencing in which postintervention normal intestinal tissue samples will be collected. The results of this study will provide evidence of the effects of acupuncture on POI and promote good clinical decision to millions of patients globally every year. ETHICS AND DISSEMINATION: This study has been approved by the ethical application of Beijing University of Chinese Medicine (2022BZYLL0401), Beijing Friendship Hospital Affiliated to Capital Medical University(2022-P2-368-02), Cancer Hospital Chinese Academy of Medical Science (23/175-3917), Huanxing Cancer Hospital (2023-002-02). The results will be published in a medical journal. In addition, we plan to present them at scientific conferences. TRIAL REGISTRATION NUMBER: ChiCTR2300077633.

Preservation of left colic artery in laparoscopic colorectal operation: The benefit challenge.

BACKGROUND: During laparoscopic resection for colorectal cancer, there is controversy regarding whether the left colic artery (LCA) should be preserved at its origin. AIM: To investigate the prognostic significance of preservation of the LCA in colorectal cancer surgery. METHODS: Patients were divided into two groups. The high ligation (H-L) technique (refers to ligation performed 1 cm from the beginning of the inferior mesenteric artery) group consisted of 46 patients, and the low ligation (L-L) technique (refers to ligation performed below the initiation of the LCA) group consisted of 148 patients. Operative time, blood loss, lymph nodes with tumor invasion, postoperative complications and recovery time, recurrence rate, and 5-year survival rate were compared between the two groups. RESULTS: The average number of lymph nodes detected in postoperative pathological specimens was 17.4/person in the H-L group and 15.9/person in the L-L group. There were 20 patients (43%) with positive lymph nodes (lymph node metastasis) in the H-L group and 60 patients (41%) in the L-L group. No statistical differences were found between the groups. Complications occurred in 12 cases (26%) in the H-L group and in 26 cases (18%) in the L-L group. The incidences of postoperative anastomotic complications and functional urinary complications were significantly lower in the L-L group. The 5-year survival rates in H-L and L-L groups were 81.7% and 81.6%, respectively, and relapse-free survival rates were 74.3% and 77.1%, respectively. The two groups were similar statistically. CONCLUSION: Complete mesenteric resection combined with lymph node dissection around the inferior mesenteric artery root while preserving the LCA is a beneficial surgical approach during laparoscopic resection for colorectal cancer.

Electroacupuncture vs Sham Electroacupuncture in the Treatment of Postoperative Ileus After Laparoscopic Surgery for Colorectal Cancer: A Multicenter, Randomized Clinical Trial.

Importance: Despite the adoption of the optimized Enhanced Recovery After Surgery (ERAS) protocol, postoperative ileus (POI) severely impairs recovery after colorectal resection and increases the burden on the health care system. Objective: To assess the efficacy of electroacupuncture (EA) in reducing the duration of POI with the ERAS protocol. Design, Setting, and Participants: This multicenter, randomized, sham-controlled trial was conducted in China from October 12, 2020, through October 17, 2021. There was a 1:1 allocation using the dynamic block random method, and analyses were by intention to treat. Patients 18 years or older undergoing laparoscopic resection of colorectal cancer for the first time were randomly assigned to treatment group by a central system. Interventions: Patients were randomly assigned to 4 sessions of EA or sham electroacupuncture (SA) after surgery. All patients were treated within the ERAS protocol. Main Outcomes and Measures: The primary outcome was the time to first defecation. Secondary outcomes included other patient-reported outcome measures, length of postoperative hospital stay, readmission rate within 30 days, and incidence of postoperative complications and adverse events. Results: A total of 249 patients were randomly assigned to treatment groups. After the exclusion of 1 patient because of a diagnosis of intestinal tuberculosis, 248 patients (mean [SD] age, 60.2 [11.4] years; 153 men [61.7%]) were included in the analyses. The median (IQR) time to first defecation was 76.4 (67.6-96.8) hours in the EA group and 90.0 (73.6-100.3) hours in the SA group (mean difference, -8.76; 95% CI, -15.80 to -1.73; P = .003). In the EA group compared with the SA group, the time to first flatus (median [IQR], 44.3 [37.0-58.2] hours vs 58.9 [48.2-67.4] hours; P < .001) and the tolerability of semiliquid diet (median [IQR], 105.8 [87.0-120.3] hours vs 116.5 [92.0-137.0] hours; P = .01) and solid food (median [IQR], 181.8 [149.5-211.4] hours vs 190.3 [165.0-228.5] hours; P = .01) were significantly decreased. Prolonged POI occurred in 13 of 125 patients (10%) in the EA group vs 25 of 123 patients (20%) in the SA group (risk ratio [RR], 0.51; 95% CI, 0.27-0.95; P = .03). Other secondary outcomes were not different between groups. There were no severe adverse events. Conclusions and Relevance: Results of this randomized clinical trial demonstrated that in patients undergoing laparoscopic surgery for colorectal cancer with the ERAS protocol, EA shortened the duration of POI and decreased the risk for prolonged POI compared with SA. EA may be considered as an adjunct to the ERAS protocol to promote gastrointestinal function recovery and prevent prolonged POI after surgery.

A Systematic Review and Single-center Experience of Azygos Vein Defibrillator Lead Insertion.

Defibrillation threshold (DFT) testing is performed in individuals with higher predicted risks of defibrillation failure. Many strategies have been explored to overcome the challenge of high DFT, including an insertion of a defibrillator lead into the azygos vein. We performed a systematic review of the literature to evaluate the safety and efficacy of azygos vein implantable cardioverter-defibrillator insertion for high DFT combined with the analysis of a single-center experience of the procedure at our institution. The literature search was performed in PubMed and Embase from database inception to December 2020 to identify all case reports and case series related to azygos vein defibrillator lead insertion. Our search identified 291 records. After excluding duplicate studies and those without DFT thresholds and non-azygos vascular destinations, 12 studies (23 cases) were reviewed from the current database. We also conducted a retrospective analysis of 5 cases performed at our institution, and a total of 28 patients were included in our final analysis. The mean age of the pooled cohort was 47 years (range, 17-88 years). Men composed 92% of the total cases, and the average body mass index was 34 kg/m2. The mean ejection fraction (EF) was 25%, with 78% having non-ischemic cardiomyopathy. The left axillary (36%) or subclavian (48%) vein was the common percutaneous access point. The mean duration of azygos vein access and lead delivery was 22 min (range, 13-60 min). The average DFT prior to azygos coil insertion was 35 J (range, 20-45 J). Fifty-seven percent of cases achieved substantial DFT improvement, whereas 18% achieved relative improvement compared to the pre-procedural threshold. No immediate or remote procedure-related complications were reported in 24 cases where data were available. During an average follow-up period of 18 months, 5 patients had ventricular arrhythmic events requiring device therapy and 4 had successful cardioversion from the device. One patient died from cardiac arrest with variable device therapies of both unsuccessful and successful events. In conclusion, azygos vein defibrillator lead insertion has a considerable rate of success, ease of vascular access with minimal procedural time, and lower risks and complications. Larger studies and longer follow-up periods are warranted to establish its efficacy and safety.

Electroacupuncture versus sham electroacupuncture in the treatment of postoperative ileus after laparoscopic surgery for colorectal cancer: study protocol for a multicentre, randomised, sham-controlled trial.

INTRODUCTION: Postoperative ileus (POI) is an inevitable complication of almost all abdominal surgeries, which results in prolonged hospitalisation and increased healthcare costs. Various treatment strategies have been developed for POI but with limited success. Electroacupuncture (EA) might be a potential therapy for POI. However, evidence from rigorous trials that evaluated the effectiveness of EA for POI is limited. Thus, the aim of this study was to examine whether EA can safely reduce the time to the first defecation after laparoscopic surgery in patients with POI. METHODS AND ANALYSIS: This multicentre randomised sham-controlled trial will be conducted in four hospitals in China. A total of 248 eligible participants with colorectal cancer who will undergo laparoscopic surgery will be randomly allocated to an EA group and a sham EA group in a 1:1 ratio. Treatment will be performed starting on postoperative day 1 and continued for four consecutive days, once per day. If the participant is discharged within 4 days after surgery, the treatment will cease on the day of discharge. The primary outcome will be the time to first defecation. The secondary outcome measures will include time to first flatus, tolerability of semiliquid and solid food, length of postoperative hospital stay, postoperative nausea and vomiting, abdominal distension, postoperative pain, postoperative analgesic, time to first ambulation, blinding assessment, credibility and expectancy and readmission rate. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of Beijing University of Chinese Medicine (number 2020BZHYLL0116) and the institutional review board of each hospital. The results will be disseminated through peer-reviewed publications. This study protocol (V.3.0, 6 March 2020) involves human participants and was approved by the ethics committees of Beijing University of Chinese Medicine (number 2020BZHYLL0116), Beijing Friendship Hospital Affiliated to Capital Medical University (number 2020-P2-069-01), Beijing Chao-Yang Hospital Affiliated to Capital Medical University (number 2020-3-11-2), National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (number 20/163-2359), and the Affiliated Hospital of Qingdao University (number QYFYKYLL711311920). The participants gave informed consent to participate in the study before taking part. TRIAL REGISTRATION NUMBER: ChiCTR2000038444.

Characteristics, trends, outcomes, and costs of stimulant-related acute heart failure hospitalizations in the United States.

BACKGROUND: Heart failure (HF) hospitalizations remains a significant burden on the health care system. Stimulants including cocaine, amphetamine and its derivatives are amongst the most used illegal substances in the United States. The information regarding stimulant-related HF hospitalizations is scarce. We sought to evaluate the characteristics and trends of stimulant-related HF hospitalizations in the United States and their associated outcomes and resource utilization. METHODS: Using the National Inpatient Sample (NIS), we identified patients with a primary diagnosis of HF hospitalization. These hospitalizations were further divided into those with and without a concomitant diagnosis of stimulant (cocaine or amphetamine) dependence or abuse. Survey specific techniques were employed to compare trends in baseline characteristics, complications, procedures, outcomes and resource utilization between the two cohorts. RESULTS: We identified 9,932,753 hospitalizations (weighted) with a primary diagnosis of heart failure, of those 138,438 (1.39%) had a diagnosis of active stimulant use. The proportion of stimulant-related HF hospitalization is on the rise (1.1% to 1.9%). Stimulant-related HF hospitalization was highest amongst age group 30-39 years and 7.9% of HF hospitalizations in this age group were due to stimulant use. The proportion of stimulant-related HF hospitalization for the White and Hispanic race has doubled from 2008 to 2017. Stimulant-related HF hospitalization is associated with increased incidence of in-hospital complications like cardiogenic shock, acute kidney injury and ventricular tachycardia. These patients have more than 7-fold higher discharge against medical advice. CONCLUSIONS: Stimulant-related HF hospitalizations have been increasing. It is associate with significant morbidity burden and health care utilization.

Impact of acute kidney injury on in-hospital outcomes among patients hospitalized with acute heart failure - A propensity-score matched analysis.

AIM: We sought to determine the impact of acute kidney injury (AKI) on in-hospital outcomes in patients presenting with acute heart failure (AHF). Data from National Inpatient Sample (2012- 14) were used to identify patients with the principal diagnosis of AHF and the concomitant secondary diagnosis of AKI. METHODS: Propensity score matching was performed on 30 baseline variables to identify a matched cohort. The outcome of interest was in-hospital mortality. We further evaluated in-hospital procedures and complications. RESULTS: Of 1,470,450 patients admitted with AHF, 24.3% had AKI. After propensity matching a matched cohort of 356,940 patients was identified. In this matched group, the AKI group had significantly higher in-hospital mortality (3.8% vs 1.7%, p<0.001). Complications such as sepsis, transfusions and cardiac arrest were also higher in the AKI group (p<0.01). Similarly, in-hospital procedures including pacemaker, coronary artery bypass graft, mechanical ventilation and intra-aortic balloon pump were performed more in the AKI group compared to the non-AKI group. The rate of AKI in patients with AHF has gradually increased from 29 % in the year 2012 to 35% in 2014. AHF patients with AKI had longer in-hospital stay of ~1.7 days. CONCLUSION: In this propensity score-matched cohort of AHF with and without AKI, the risk of in-hospital mortality was >2-fold in the AKI group. Healthcare utilization and burden of complications were higher in the AKI group.

Epicardial bridge via the coronary sinus musculatures revealed by ultra-high-definition mapping.

Mapping and ablation of perimitral flutter, a macro-reentrant tachycardia, can be sometimes challenging. We describe a case of perimitral atrial flutter following the pulmonary vein isolation in which mitral isthmus ablation failed to terminate the arrhythmia due to epicardial-endocardial breakthrough via the muscle fibers of coronary sinus. Ultra-high-definition mapping system was utilized to locate the epicardial bridge, and spot ablation of the lesion subsequently terminated the arrhythmia.

Transanal total mesorectal excision for rectal cancer: a multicentric cohort study.

BACKGROUND: Transanal total mesorectal excision (taTME) has recently emerged as a promising novel surgical procedure for rectal cancer. It is believed to hold the potential advantage of providing better access to mobilize the distal rectum and achieving better pathologic results. This study aimed to evaluate the feasibility of taTME for rectal cancer and summarize the preliminary experience in 10 Chinese hospitals. METHODS: A total of 211 patients were enrolled in this study. Variables for evaluation of safety, feasibility, and oncologic outcomes were retrospectively collected and analysed. RESULTS: The median distance between the tumor and the anal verge was 5.9 cm (range, 1.5-12 cm). The median operating time was 280 min (range, 70-600 min) and the median estimated intra-operative blood loss was 50 mL (range, 10-1,500 mL). The overall rate of complication was 27.9%. Among the 211 patients, 175 (82.9%) had complete TME and 33 (15.6%) had near complete TME. The circumferential resection margin was negative in 97.7% of patients. The patients were followed for a median of 35 months (range, 2-86 months). There was 7.6% (16) mortality, 6.2% (13) had local recurrence, and 12.8% (27) had systemic recurrence. Kaplan-Meier survival analysis showed that 1-, 2-, and 3-year disease-free survival rates were 94.8%, 89.3%, and 80.2%, respectively, and 1-, 2-, and 3-year OS rates were 97.4%, 95.7%, and 92.9%, respectively. CONCLUSIONS: Although limited by its retrospective nature, taTME was safe and feasible in selected patients. Future work with rigorous data recording is warranted.

Utility of circulating tumor cells in stage II colorectal cancer patients undergoing curative resection.

BACKGROUND: The aim of this study was to determine whether circulating tumor cells (CTCs) have utility as a prognostic biomarker in stage II colorectal cancer (CRC), as well as a biomarker for the selection of patients for adjuvant chemotherapy. METHODS: CTCs were detected in peripheral blood samples obtained from 73 stage II CRC patients, using a negative enrichment and immune-fluorescence in situ hybridization (imFISH) staining method. The follow-up time ranged from 3.5 to 35.9 months, and the clinic-pathologic characteristics and recurrence free survival (RFS) were collected and analyzed. RESULTS: Seventy-three stage II CRC patients were included in this study. The positive rate of CTCs was 65.8% in all patients, 87.5% in recurrent patients and 59.6% in no recurrence patients. The mean RFS was 30.6 months for all patients, 28.7 months for CTC-positive patients and 34.0 months for CTC-negative patients (P=0.043). The mean RFS of CTC-positive and CTC-negative patients with adjuvant chemotherapy were not reached, and those without adjuvant chemotherapy were 27.7 and 33.4 months, respectively. CONCLUSIONS: The level of CTCs may be an effective prognostic factor to predict RFS in stage II CRC patients, and has potential in selecting stage II CRC patients for adjuvant chemotherapy.

Direct Current Ablation of Deep Substrate Arrhythmia.

Direct-current ablation has been reinvestigated in animal models with considerably good outcomes and safety margins. Its modified version using biphasic energy lowers the current density further, minimizing its complications. We report a first-in-human ablation of ventricular tachycardia using biphasic direct current with short-term success and no procedural complications. (Level of Difficulty: Intermediate.).

Clozapine-Induced Cardiotoxicity Presenting as Sepsis: A Case Report and Literature Review.

Clozapine is an atypical antipsychotic agent indicated in the treatment of medication-resistant schizophrenia. It is often reserved as a last line of treatment owing to the potential for serious and potentially life-threatening side effects, the most serious being agranulocytosis requiring close hematological monitoring and possible discontinuation of the medication from further use in the patient even when the agranulocytosis resolves. Other complications of clozapine include sedation, weight gain, elevated triglyceride levels, postural hypotension, and tachycardia. However, the potentially serious complication of myocarditis, though rare (with an incidence of 3%), may lead to cardiomyopathy as described in our present case. We present a 21-year-old patient who was started on clozapine for management of schizophrenia. He developed fever and tachycardia and was admitted to the medical unit on intravenous antibiotics for management of sepsis as he met the criteria for systemic inflammatory response syndrome. His labs revealed an elevated troponin and trending eosinophilia, which, in the context of clozapine use, raises the suspicion of clozapine cardiotoxicity. Echocardiogram showed reduced systolic function (45%). Clozapine was immediately discontinued, and his repeat echocardiogram showed normalization of his systolic function. In view of the increased prevalence of psychiatric illnesses, internists should be aware of rare but potentially life-threatening side effects.

Air Entrapment Causing Inappropriate Shock From a Subcutaneous Implantable Cardioverter Defibrillator.

Subcutaneous implantable cardioverter defibrillator (S-ICD) is an accepted alternative to conventional transvenous devices. Their efficacy in arrhythmia management is comparable to ICDs. However, those devices also have limitations such as lack of anti-tachycardia pacing capability or higher occurrence of device oversensing associated with inappropriate shocks. Air entrapment inside one or more of subcutaneous pockets has been reported as one of uncommon causes of device malfunction. It is important to recognize the wandering or drifting baseline signals during device interrogation for timely diagnosis and appropriate treatment.

Utility of Intracardiac Echocardiography to Diagnose Infective Endocarditis.

Infective endocarditis (IE) can lead to significant morbidity and mortality without appropriate treatment. Modified Duke Criteria are accepted by many professional societies to establish the diagnosis of IE, and cardiac imaging is one of the major diagnostic criteria. Transesophageal echocardiography is an algorithmic escalation to diagnose IE when transthoracic echo does not appreciate a positive finding. In patients with contraindications to transesophageal echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography (CT), cardiac CT angiography, and fluorodeoxyglucose positron emission tomography with CT or CT angiography may be alternative diagnostic tools. However, these imaging modalities have their own limitations such as local unavailability, the presence of non-magnetic resonance imaging compatible implants, or impaired renal function. Intracardiac echocardiography could be a considerable alternative under those circumstances.

Inappropriate Defibrillator Shocks due to Mechanical Inference from an Investigational Device.

Cardiac contractility modulation (CCM) is an investigational device-based therapy to enhance ventricular contractility in systolic heart failure patients who are not candidates for cardiac resynchronization therapy (CRT) owing to the absence of wide QRS complexes or who have failed to respond on CRT. The principal mechanism is based on the stimulation of cardiac muscles by nonexcitatory electrical signals to augment the influx of calcium ions into the cardiomyocytes. The majority of patients receiving CCM therapy have concurrent implantable cardioverter defibrillators, and the manufacturer declares both devices can be used in parallel without any interactions. Nevertheless, proper lead positioning of both devices are crucial, and it is mandatory to check device-device interactions during each and every cardiac electronic implantable device-related procedure to prevent adverse outcomes.

A Case of Complete Heart Block With Diagnostic Challenge and Therapeutic Dilemma.

Permanent pacemaker implantation is a class I indication for all symptomatic patients with complete heart block either congenital or acquired. However, certain portions of patients with congenital complete heart block are asymptomatic. Those patients are often very young, and implanting a permanent pacemaker is not always an easy decision. A therapeutic dilemma arises when a select patient population does not meet certain criteria to gain the maximum benefits out of prophylactic pacemaker therapy. Most asymptomatic patients with congenital complete heart block will eventually become symptomatic and require pacemakers at some point in their life but the definitive answer for the ideal time to initiate pacemaker therapy in such population has not been established. We present a case of asymptomatic congenital complete heart block with junctional escape rhythm, which is capable of incrementing the heart rate with physical activity to result in a challenge in diagnosis as well as the treatment strategy.

Circulating tumor DNA detectable in early- and late-stage colorectal cancer patients.

Characterization, diagnosis, and treatment of colorectal cancers (CRC) is difficult due to limited biopsy information, impracticality of repeated biopsies, and cancer biomarker fallibility. Circulating tumor DNA (ctDNA) has recently been investigated as a non-invasive way to gain representative gene mutations in tumors, in addition to monitoring disease progression and response to treatment. We analyzed ctDNA mutations and concentrations in 47 early- and late-stage CRC patients using a targetted sequencing approach using a panel that covers 50 cancer-related genes. ctDNA mutations in 37 genes were identified in 93.6% of the patients (n=47). The results showed that TP53, PIK3CA, APC, and EGFR were the most frequently mutated genes. Stage IV patients had significantly higher ctDNA concentration than Stage I patients, and increased ctDNA concentration correlated with increased tumor size. Additionally, ctDNA detection was found to be a greater predictor of disease when compared with five known commonly used tumor biomarkers. The present study supports the use of ctDNA as a liquid biopsy to gain clinical tumor information that may facilitate early diagnosis and treatment and improve CRC patient prognosis.

[Feasibility and Safety of Enhanced Recovery after Surgery for Elderly Patients with Colorectal Cancer].

Objective To evaluate the feasibility and safety of enhanced recovery after surgery (ERAS) in elderly patients with colorectal cancer (CRC).Methods A retrospective analysis was conducted on 230 CRC patients undergoing ERAS from January 2017 to January 2018. These subjects included 120 young patients (<70 years) and 110 elderly patients (≥70 years).The rates of ERAS compliance,anastomotic leakage,re-operation,and re-hospitalization,the mortality,and the average hospital stay were compared between these two groups.Results The elderly group had significantly higher incidences including diabetes (20.9% vs. 10.8%,P=0.045),heart disease (24.5% vs. 11.7%,P=0.039),respiratory diseases (20.0% vs. 10.0%,P=0.041),and hypertension (26.4% vs. 15.0%,P=0.035) than the young group. However,these two groups were not statistically significant in terms of ERAS compliance rate (79% in the young group vs. 74% in the elderly group,P=0.574),incidence of anastomotic leakage (2.5% vs. 1.8%,P=1.000),re-operation rate (1.7% vs. 2.7%,P=0.672),re-hospitalization rate (2.5% vs. 4.5%,P=0.484),mortality rate within 30 days after operation (1.7% vs. 2.7%,P=0.672). The average hospital stay was 5 days in the young group and 7 days in the elderly group (P=0.000).Conclusions Although the elderly patients tend to have poor general status,their ERAS compliance rate and main treatment indicators including incidence of anastomotic leakage,re-operation rate,re-hospitalization rate,and mortality rate within 30 days after surgery are not different from young patients. Thus,the ERAS program is safe and feasible for elderly CRC patients.

Laparoscopic-assisted Transanal Total Mesorectal Excision for Middle-Low Rectal Carcinoma: A Clinical Study of 19 Cases.

AIM: To explore the safety, feasibility and short-term outcomes of laparoscopic-assisted transanal total mesorectal excision (La-TaTME) of middle-low rectal carcinoma. MATERIALS AND METHODS: This retrospective research collected and analyzed the clinical data of 19 patients diagnosed with middle and low rectal carcinoma who underwent La-TaTME from August 2015 to February 2017. RESULTS: No case was converted to laparotomy. In none of the enrolled cases, did the circumferential resection margin test positive by histopathology examination. Also, there was no detected residual tumor at the proximal and distal resection margins. The rate of postoperative morbidity was 15.8% (Clavien-Dindo grade 2). During the follow-up period, no local recurrence or metastasis was observed. CONCLUSION: La-TaTME is a safe alternative to standard laparoscopic TME in middle-low rectal carcinoma when operated by an experienced colorectal surgeon. However, large-scaled randomized multi-centered comparative trials are still needed to further test its oncological effectiveness.
