Abstract
BACKGROUND Transanal total mesorectal excision is a novel surgical treatment for mid to low rectal cancers. Norwegian population data have raised concerns about local recurrence in patients treated with transanal total mesorectal excision. OBJECTIVE This study aimed to analyze local recurrence and disease-free survival in patients treated by transanal total mesorectal excision for rectal cancer at a high-volume tertiary center. DESIGN This retrospective study used a prospectively maintained institutional transanal total mesorectal excision database. Patient demographics, treatment, and outcomes data were analyzed. Local recurrence, disease-free survival, and overall survival were analyzed using Kaplan-Meier analysis. SETTINGS The study was conducted at a single academic institution in Vancouver, Canada. PATIENTS All patients treated by transanal total mesorectal excision for rectal adenocarcinoma between 2014 and 2022 were included. MAIN OUTCOME MEASURES The primary outcome was local recurrence-free survival. RESULTS Between 2014 and 2022, 306 patients were treated by transanal total mesorectal excision at St. Paul's Hospital. Of these, 279 patients met the inclusion criteria. The mean age was 62 years (SD ± 12.3), and 66.7% of patients were men. Restorative resection was achieved in 97.5% of patients, with a conversion rate from laparoscopic to open surgery of 6.8%. The composite optimal pathological outcome was 93.9%. The median follow-up was 26 months (interquartile range, 12-47), and 82.8% of patients achieved reestablishment of GI continuity to date. The overall local recurrence rate was 4.7% (n = 13). The estimated 2-year local recurrence-free survival rate was 95.0% (95% CI, 92-98) and the estimated 5-year local recurrence-free survival rate was 94.5% (95% CI, 91-98). LIMITATIONS Limitations include the retrospective nature of the study and the generalizability of a Canadian population. CONCLUSIONS Recent European data have challenged the presumed oncologic safety of transanal total mesorectal excision. Although the learning curve for this procedure is challenging and poor outcomes are associated with low volume, this high-volume single-center study confirms acceptable oncologic outcomes consistent with the current standard.

SOBREVIDA SIN RECIDIVA DESPUS DE TATME EXPERIENCIA INSTITUCIONAL CANADIENSE ANTECEDENTES:La excisión total del mesorecto por vía transanal es un tratamiento quirúrgico novedoso para los cánceres de recto medio a bajo. Estudios sobre la población noruega han generado preocupación debido a la recidiva local en pacientes tratados con excisión total del mesorecto por vía transanal.OBJETIVO:Nuestra finalidad fué de analizar la recidiva local y la sobrevida libre de enfermedad en pacientes tratados mediante la excisión total del mesorecto por vía transanal, debido a un cáncer de recto en un centro terciario de alto volúmen.DISEÑO:El presente estudio retrospectivo, utiliza una base de datos institucional sobre la excisión total del mesorecto por vía transanal mantenida prospectivamente. Se analizaron los datos demográficos, de tratamiento y los resultados de los pacientes sometidos a la técnica mencionada. La recidiva local, la sobrevida libre de enfermedad y la sobrevida global se analizaron mediante el modelo de Kaplan-Meier.AJUSTES:El estudio se llevó a cabo en una sola institución académica en Vancouver, Canadá.PARTICIPANTES:Se incluyeron todos los pacientes tratados mediante excisión total del mesorecto por vía transanal causado por adenocarcinomas de recto entre 2014 y 2022.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la sobrevida libre de recidiva local.RESULTADOS:Entre 2014 y 2022, 306 pacientes fueron tratados mediante la excisión total del mesorecto por vía transanal en el Hospital St. Paul. De estos, 279 pacientes cumplieron los criterios de inclusión. La edad media fue de 62 años (DE ± 12,3) y el 66,7% de los pacientes eran varones. La resección restauradora se logró en el 97,5% de los pacientes con una tasa de conversión de cirugía laparoscópica en laparotomía del 6,8%. El resultado patológico óptimo combinado fué del 93,9%. La mediana de seguimiento fue de 26 meses (rango intercuartil 12-47) y el 82,8% logró el restablecimiento de la continuidad gastrointestinal hasta la fecha. La tasa global de recidiva local fué del 4,7% (n = 13). La sobrevida libre de recidiva local estimada a los 2 años fué del 95,0% (IC del 95%: 92-98) y del 94,5% a los 5 años (IC del 95%: 91-98).LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva del estudio y la generalización de una población canadiense.CONCLUSIONES:Datos europeos recientes han cuestionado la supuesta seguridad oncológica de la excisión total del mesorecto por vía transanal. Si bien la curva de aprendizaje de este procedimiento es muy desafiante y los malos resultados se asocian con un volumen bajo, el presente estudio, unicéntrico de gran volumen confirma los resultados oncológicos aceptables consistentes con el estándar actual.

Abstract
BACKGROUND Transanal TME (taTME) combines abdominal and transanal dissection to facilitate sphincter preservation in patients with low rectal tumors. Few phase II/III trials report long-term oncologic and functional results. We report early results from a North American prospective multicenter phase II trial of taTME (NCT03144765). METHODS 100 patients with stage I-III rectal adenocarcinoma located ≤ 10 cm from the anal verge (AV) were enrolled across 11 centers. Primary and secondary endpoints were TME quality, pathologic outcomes, 30-day and 90-day outcomes, and stoma closure rate. Univariable regression analysis was performed to assess risk factors for incomplete TME and anastomotic complications. RESULTS Between September 2017 and April 2022, 70 males and 30 females with median age of 58 (IQR 49-62) years and BMI 27.8 (IQR 23.9-31.8) kg/m2 underwent 2-team taTME for tumors located a median 5.8 (IQR 4.5-7.0) cm from the AV. Neoadjuvant radiotherapy was completed in 69%. Intersphincteric resection was performed in 36% and all patients were diverted. Intraoperative complications occurred in 8% including 3 organ injuries, 2 abdominal and 1 transanal conversion. The 30-day and 90-day morbidity rates were 49% (Clavien-Dindo (CD) ≥ 3 in 28.6%) and 56% (CD ≥ 3 in 30.4% including 1 mortality), respectively. Anastomotic complications were reported in 18% including 10% diagnosed within 30 days. Higher anastomotic risk was noted among males (p = 0.05). At a median follow-up of 5 (IQR 3.1-7.4) months, 98% of stomas were closed. TME grade was complete or near complete in 90%, with positive margins in 2 cases (3%). Risk factors for incomplete TME were ASA ≥ 3 (p = 0.01), increased time between NRT and surgery (p = 0.03), and higher operative blood loss (p = 0.003). CONCLUSION When performed at expert centers, 2-team taTME in patients with low rectal tumors is safe with low conversion rates and high stoma closure rate. Mid-term results will further evaluate oncologic and functional outcomes.

Abstract
Aim To evaluate the efficacy and safety of simple TaTNE in the treatment of low rectal cancer compared with laparoscopic transabdominal TME. Methods We collected patients with low rectal cancer admitted to our hospital between January 2019 and November 2021 who received simple TaTME or laparoscopic transabdominal TME. The main outcome was the integrity of the TME specimen. Secondary outcomes were the number of lymph nodes dissected, intraoperative blood loss, operative time, surgical conversion rate, Specimen resection length, circumferential margin (CRM), and distal resection margin (DRM), complication rate. In addition, the Wexner score and LARS score of fecal incontinence were performed in postoperative follow-up. Results Pathological tissues were successfully resected in all patients. all circumferential margins of the specimen were negative. Specimen resection length was not statistically significant (9.94 ± 2.85 vs. 8.90 ± 2.49, P > 0.05). The incidence of postoperative complications in group A (n = 0) was significantly lower than that in group B (n = 3) (P > 0.05). There was no significant difference in operation time between group A and group B (296 ± 60.36 vs. 305 ± 58.28, P > 0.05). Among the patients with follow-up time less than 1 year, there was no significant difference in Wexner score and LARS score between group A and group B (P > 0.05). However, in patients who were followed up for more than 1 year, the Wexner score in group A (9.25 ± 2.73) was significantly lower than that in group B (17.36 ± 10.95) and was statistically significant (P < 0.05). Conclusion For radical resection of low rectal cancer, Simple TaTME resection may be as safe and effective as laparoscopic transabdominal TME, and the long-term prognosis may be better.

Abstract
BACKGROUND Although transanal total mesorectal excision (TaTME) is a promising treatment for low rectal cancer, it is considered technically demanding, and the number of cases required to become proficient in TaTME remains unknown. The purpose of this study was to assess the TaTME learning curve based on the total mesorectal excision completion time. STUDY DESIGN This retrospective analysis comprised 128 individuals who received TaTME between September 2016 and December 2021. The cumulative sum method was used to generate the learning curve. The duration of the procedure from the beginning to the end of the circumferential rendezvous was used to define the total mesorectal excision completion time. RESULTS The learning curve consists of 3 phases: phase I (learning phase: cases 1 to 38), phase II (consolidation phase: cases 39 to 70), and phase III (maturing phase: cases 71 to 128). As the phases varied, both the overall operative time and total mesorectal excision completion time decreased considerably. Through the 3 phases of TaTME, intraoperative adverse events decreased, and in phase III, none occurred. Only 1 instance of local recurrence occurred during phase III, and none occurred during phase I or II. CONCLUSIONS After 70 operations, the surgeon could join the mastery phase of TaTME based on the total mesorectal excision completion time. After the mastering phase began, there were no intraoperative negative occurrences. From the beginning, the oncological safety could be guaranteed.

Incidence and Risk Factors of Surgical Complications and Anastomotic Leakage After Transanal Total Mesorectal Excision for Middle and Low Rectal Cancer. J Gastrointest Surg 2023; 27:373-381. [PMID: 36538254 DOI: 10.1007/s11605-022-05546-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 11/19/2022] [Indexed: 01/20/2023]
Abstract
PURPOSE Transanal total mesorectal excision (taTME) is a promising surgical procedure for middle and low rectal cancer; however, it is linked to significant morbidity. This study aimed to determine the incidence of postoperative surgical complications and anastomotic leakage following taTME and to identify their associated risk factors. METHODS The prospective clinical data of 114 patients, who underwent taTME and primary anastomosis for mid-low rectal cancer between November 2016 and June 2022, were retrospectively analyzed. Univariate and multivariate analyses were performed to identify clinical characteristics and risk factors for predicting surgical complications and anastomotic leakage. RESULTS Surgical complications occurred in 40 (35.1%) patients within the first 30 days following surgery. Based on the Clavien-Dindo classification, minor complications (Clavien-Dindo grades I + II) accounted for 30.7%, while major complications (Clavien-Dindo grades III + IV) accounted for only 4.4%. None of the patients died within 30 days. The incidence of anastomotic leakage was 15.8%: 4.4% as grade A (5 cases), 9.6% as grade B (11 cases), and 1.8% as grade C (2 cases). Preoperative T3-4 was identified as an independent risk factor for surgical complications (p = 0.031) by multivariate analysis. American Society of Anesthesiology score ≥ 3 (P = 0.021) and incomplete total mesorectal excision specimens (P = 0.030) were significantly associated with the risk of anastomotic leakage. CONCLUSIONS In this study, the incidence of surgical complications and anastomotic leakage in taTME aligned with previously reported rates. Preoperative T3-4 was significantly associated with surgical complications. American Society of Anesthesiology score ≥ 3 and incomplete TME specimens independently increased the risk of anastomotic leakage.

Abstract
OBJECTIVE To determine the morbidity, mortality, and pathologic outcomes of transanal total mesorectal resection (taTME) versus laparoscopic total mesorectal excision (laTME) among patients with rectal cancer with clinical stage I to III rectal cancer below the peritoneal reflection. BACKGROUND Studies with sufficient numbers of patients allowing clinical acceptance of taTME for rectal cancer are lacking. Thus, we launched a randomized clinical trial to compare the safety and efficacy of taTME versus laTME. METHODS A randomized, open-label, phase 3, noninferiority trial was performed at 16 different hospitals in 10 Chinese provinces. The primary endpoints were 3-year disease-free survival and 5-year overall survival. The morbidity and mortality within 30 days after surgery, and pathologic outcomes were compared based on a modified intention-to-treat principle; this analysis was preplanned. RESULTS Between April 13, 2016, and June 1, 2021, 1115 patients were randomized 1:1 to receive taTME or laTME. After exclusion of 26 cases, modified intention-to-treat set of taTME versus laTME groups included 544 versus 545 patients. There were no significant differences between taTME and laTME groups in intraoperative complications [26 (4.8%) vs 33 (6.1%); difference, -1.3%; 95% confidence interval (CI), -4.2% to 1.7%; P =0.42], postoperative morbidity [73 (13.4%) vs 66 (12.1%); difference, 1.2%; 95% CI, -2.8% to 5.2%; P =0.53), or mortality [1 (0.2%) vs 1 (0.2%)]. Successful resection occurred in 538 (98.9%) versus 538 (98.7%) patients in taTME versus laTME groups (difference, 0.2%; 95% CI, -1.9% to 2.2%; P >0.99). CONCLUSIONS Experienced surgeons can safely perform taTME in selected patients with rectal cancer.

Ban B, Shang A, Shi J. Efficacy of staple line reinforcement by barbed suture for preventing anastomotic leakage in laparoscopic rectal cancer surgery. World J Gastrointest Surg 2022; 14:821-832. [PMID: 36157360 PMCID: PMC9453327 DOI: 10.4240/wjgs.v14.i8.821] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/28/2022] [Accepted: 07/26/2022] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Anastomotic leakage (AL) is a severe complication in rectal cancer surgery. Various methods, including intracorporeal reinforcing suturing, have been used to reduce the incidence of AL. However, little is known about the efficacy of staple-line reinforcement by barbed suture for preventing AL.
AIM To evaluate the efficacy of staple-line reinforcement using barbed suture for preventing AL in laparoscopic surgery for rectal cancer.
METHODS We retrospectively reviewed the clinical datum of 319 patients undergoing laparoscopic low anterior resection combined with double stapling technique between May 1, 2017 and January 31, 2021. All surgeries were performed by the same surgical team specializing in colorectal surgery. Patients were divided into two groups depending on whether they received reinforcing sutures. Patients’ baseline characteristics did not show any significant difference between the two groups. We analyzed patient-, tumor-, as well as surgery-related variables using univariate and multivariate logistic analyses.
RESULTS There were 168 patients in the reinforcing suture group and 151 patients in the non-reinforcing suture group. AL occurred in 25 cases (7.8%). Its incidence was significantly higher in the non-reinforcing suture group than in the reinforcing suture group (4.8% vs 11.3%, P = 0.031). The multivariate analyses demonstrated that the tumor site, tumor size and presence of staple-line reinforcement were independent risk factors for AL. We divided these patients into two risk groups based on the combination of tumor site and tumor size. Patients without any risk factor were assigned to the low-risk group (n = 177), whereas those having one or two risk factors were assigned to the high-risk group (n = 142). In the high-risk group, the AL incidence considerably decreased in the reinforcing suture group compared with that in the non-reinforcing suture group (P = 0.038). Nonetheless, no significant difference was found in the low-risk group between the two groups.
CONCLUSION Staple-line reinforcement by barbed suture may decrease the incidence of AL. A large-scale prospective randomized controlled trial is needed for evaluating the efficacy of staple-line reinforcement for preventing AL.

Abstract
BACKGROUND Recent series have raised concerns about the oncologic outcomes of transanal total mesorectal excision for mid and low rectal cancer. There is a paucity of large data sets from the United States to contribute to the ongoing international discourse. OBJECTIVE This study aimed to investigate the rate of local recurrence and other oncologic outcomes in patients undergoing transanal total mesorectal excision for rectal adenocarcinoma. DESIGN This study is a retrospective review of patients undergoing transanal total mesorectal excision for primary rectal cancer from January 2014 to December 2019. SETTINGS This study was conducted at a single academic tertiary care medical center in the United States. PATIENTS Consecutive patients aged ≥18 years undergoing surgical resection for primary rectal cancer were selected. INTERVENTION The transanal total mesorectal excision procedures were performed utilizing a 2-team approach. MAIN OUTCOME MEASURES Primary outcomes were pathologic quality, local and distant recurrence, treatment-related complications, and overall- and cancer-specific survival. RESULTS Seventy-nine consecutive patients were included. The median age was 58 years (interquartile range, 50-64), and median BMI was 28 kg/m2 (interquartile range, 24.6-32.4). The mesorectum was complete in 69 patients (87.3%), nearly complete in 9 (11.4%), and incomplete in 1 (1.3%). There was circumferential resection margin involvement (<1 mm) in 4 patients (5.1%), and no patients had a positive distal margin (<1 mm) or intraoperative rectal perforation. Composite optimal pathology was achieved in 94.9% of specimens. Median follow-up was 29 months (range, 6-68). There were no local recurrences. Distant metastases were found in 10 (13.5%) patients and diagnosed after a median of 14 months (range, 0.6-53). Disease-free survival was 91.2% at 2 years, and overall survival was 94.7% at 2 years. LIMITATIONS Retrospective design, a single center, and relatively short follow-up period were limitations of this study. CONCLUSION The oncologic outcomes of this cohort support the use of transanal total mesorectal excision in the surgical management of mid to low rectal cancer at centers with appropriate expertise.

Abstract
Low rectal cancer has always posed surgical challenges to gastrointestinal surgeons. Transanal total mesorectal excision (taTME) is a novel approach to radical resection for low rectal cancer. Compared with conventional laparoscopic TME (laTME), taTME is relevant to the benefits of better vision of the mesorectal plane, feasibility of operating in a narrow pelvis, and exact definition of distal resection margin, which may lead to a higher possibility of free circumferential resection margin, better quality of TME specimen, and lower conversion rate. Although there are concerns about its long-term oncological outcomes and complex learning curve, taTME is a promising alternative for rectal cancer. In this review, we discuss the application status and prospects of taTME.

Transanal Transection and Single-Stapled Anastomosis (TTSS): A comparison of anastomotic leak rates with the double-stapled technique and with transanal total mesorectal excision (TaTME) for rectal cancer. Eur J Surg Oncol 2021; 47:3123-3129. [PMID: 34384655 DOI: 10.1016/j.ejso.2021.08.002] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 08/04/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND in the literature on rectal cancer (RC) surgery many studies have focused on the quality of total mesorectal excision (TME) dissection, while there is a scarcity of comparative data on transection and anastomosis. No anastomosis has so far proved to be superior to any other. The aim of this study was to compare anastomotic leak (AL) rates between conventional laparoscopic double-stapled (DS), transanal total mesorectal excision (TaTME) and Transanal Transection and Single-Stapled anastomosis (TTSS) techniques. METHODS consecutive mid-low RC patients undergoing elective laparoscopic TME with stapled anastomosis and protective stoma, by either DS, TaTME or TTSS techniques were retrieved from a prospectively collected database. RESULTS 127 DS; 100 TaTME and 50 TTSS were included. Demographics, distance of the tumor from anal verge and neoadjuvant therapy were comparable. Operative time was longer in TaTME over DS and TTSS (p < 0.0001). More 90-days complications occurred in DS group vs TTSS (p = 0.029). The AL rate was 17.5% in DS, 6% in TaTME and 2% in TTSS group (p = 0.005). AL grade was: one B (2%) in TTSS; 2 grade B (2%) and 4 grade C (4%) in TaTME; 6 grade A (4.7%), 7 grade B (5.5%) and 9 grade C (7.1%) in DS group. Reintervention rate after AL was higher in DS group over TTSS (12.6% vs 2%; p = 0.003). The rate of stoma closure, pathology data and margin positivity did not differ. CONCLUSIONS TTSS strategy is feasible, safe and leads to very low AL rates after TME for RC.

Abstract
BACKGROUND AND OBJECTIVES Transanal total mesorectal excision is a surgical procedure for mid- and low rectal cancer. The Chinese TaTME Registry Collaborative is a nationwide database collecting information on patients who have undergone this procedure. METHODS Centers were invited by the registry committee to participate in a three-part data audit project: remote audits for data completeness and deviation values, onsite source verification of data accuracy, and an online survey of the characteristics of data managers. RESULTS Twenty-three tertiary centers participated in this project. The median case volume registered by the centers was 51 (interquartile range, 25-89). The overall data completeness for 30 verified variables was 89.1%. Eight centers achieved a high data completeness rate (>95%). The source data of eight centers were verified onsite. The overall accuracy rate was 90.4% (85.3%-97.6% across centers). Postoperative complications, mortality, and proximal/distal resection margin involvement were accurately reported in >95% of cases. The data completeness rate was higher if the data manager was a surgeon/surgical resident (94.2% vs. 84.8%, p = 0.045). CONCLUSIONS The completeness and accuracy of the data in the Chinese TaTME Registry Collaborative are acceptable. The quality of the data is highest when entered by colorectal surgeons and residents.
