Abstract Background Since 2010, laparoscopic transanal total mesorectal excision (TaTME) has been increasingly used for low and very low rectal cancer. It is supposed to improve visibility and access to the dissection planes in the pelvis. This study reports on short- and long-term outcomes of the first 100 consecutive patients treated with TaTME in a certified German colorectal cancer center. Patients and methods Data were derived from digital patient files and official cancer registry reports for patients with TaTME tumor surgery between July 2014 and January 2020. The primary outcome was the 3-year local recurrence rate and local recurrence-free survival (LRFS). Secondary endpoints included overall survival (OAS), disease-free survival (DFS), operation time, completeness of local tumor resection, lymph node resection, and postoperative complications. The Kaplan–Meier method was employed for the survival analyses; competing risks were considered in the time-to-event analysis. Results During the observation period, the average annual operation time decreased from 272 to 178 min. Complete local tumor resection was achieved in 97% of the procedures. Major postoperative complications (Clavien–Dindo 3–4) occurred in 11% of the cases. At a median follow-up time of 2.7 years, three patients had suffered from a local recurrence. Considering competing risks, this corresponds to a 3-year cumulative incidence rate for local recurrence of 2.2% and a 3-year LRFS of 81.9%. 3-year OAS was 82.9%, and 3-year DFS was 75.7%. Conclusion TaTME is associated with favorable short and long-term outcomes. Since it is technically demanding, structured training programs and more research on the topic are indispensable.

Abstract   Nowadays, there is still no consensus about the benefits of adding neck lymphadenectomy to the traditional two-fields esophagectomy. An extended lymphadenectomy could potentially increase operation time and the risks for postoperative complications. However, extended lymphadenectomy allows resection of cervical nodes at risk for metastases, potentially increasing long-term survival rates. This study aims to estimate whether cervical prophylactic lymphadenectomy for esophageal cancer influences short- and long-term outcomes through a systematic review of literature and meta-analysis. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central, and Lilacs (BVS). The inclusion criteria were: (1) studies that compare two-field vs. three-field esophagectomy; (2) adults (>18 years); (3) articles that analyze short- or long-term outcomes; and (4) clinical trials or cohort studies. The results were summarized by forest plots, with effect size (ES) or risk difference (RD) and 95% CI. Results Twenty-five articles were selected, comprising 8,954 patients. Three-field lymphadenectomy was associated to higher operation time (ES: -1.51; 95%CI -1.84, −1.18) and higher blood loss (ES: -0.24; 95%CI: −0.37, −0.11). Also, neck lymphadenectomy inputs additional risk for pulmonary complications (RD: 0.03; 95%CI: 0.01, 0.05). No difference was noted for morbidity (RD: 0.01; 95%CI: −0.01, 0.03); leak (−0.02; 95%CI: −0.07, 0.03); postoperative mortality (RD: 0.00; 95%CI: −0.00, 0.01), and hospital stay (ES: -0.05; 95%CI -0.20, 0.10). Three-field lymphadenectomy allowed higher number of retrieved lymph nodes (MD: -1.51; 95%CI -1.84, −1.18), but did not increase the overall survival (HR: 1.11; 95%CI: 0.96, 1.26). Conclusion Prophylactic neck lymphadenectomy for esophageal cancer should be performed with caution once it is associated with poorer short-term outcomes compared to traditional two-field lymphadenectomy and does not improve long-term survival. Future esophageal cancer studies should determine the subgroup of patients who could benefit from prophylactic neck lymphadenectomy in long-term outcomes.

Abstract OBJECTIVES Our goal was to compare short- and long-term outcomes between 3-field lymphadenectomy (3-FL) and modern 2-field lymphadenectomy (2-FL) in patients with thoracic oesophageal squamous cell carcinoma. METHODS We reviewed clinical outcomes for 298 patients with thoracic oesophageal squamous cell carcinoma who underwent 3-FL or modern 2-FL from March 2008 to December 2013 at a major cancer hospital in Guangzhou, southern China. Propensity score matching was used to balance baseline differences, and 83 pairs of cases were selected. Postoperative complications, recurrence patterns and survival outcomes were compared between the 2 groups. RESULTS Compared with modern 2-FL, 3-FL led to higher overall operative morbidity rates [78.3% vs 61.4%, odds ratio (OR) 2.266, 95% confidence interval (CI) 1.143–4.490; P = 0.019], with higher recurrent nerve palsy rates (47.0% vs 19.3%, OR 3.712, 95% CI 1.852–7.438; P < 0.0001), more respiratory failures (18.1% vs 6.0%, OR 3.441, 95% CI 1.189–9.963; P = 0.023) and longer postoperative hospital stays (23 vs 17 days, P = 0.002). The 5-year overall survival rate (58.5% vs 59.4%; P = 0.960) and the 5-year disease-free survival rate 50.1% vs 54.5%; P = 0.482) were comparable between the 2 groups. Multivariable analysis showed that additional cervical lymph node dissection was not associated with overall survival [hazard ratio (HR) 1.039, 95% CI 0.637–1.696; P = 0.878] and disease-free survival (HR 0.868, 95% CI 0.548–1.376; P = 0.547). The overall recurrence rate and cervical nodal recurrence rate were not significantly different between the 2 groups. CONCLUSIONS Additional cervical lymphadenectomy did not lead to added survival benefit when compared with modern 2-FL in patients with thoracic oesophageal squamous cell carcinoma. Recurrence was similar in patients undergoing 3-FL and modern 2-FL. 3-FL resulted in more postoperative complications.

Abstract Introduction Ventricular tachycardia substrate ablation (VTSA) incorporating hidden slow conduction (HSC) analysis allows further arrhythmic substrate identification. This study evaluates whether the analysis and elimination of HSC electrograms (HSC-EGMs) during VTSA procedures result in better short and long-term outcomes.  Methods Consecutive patients (n = 70, 63% ischaemic, 64 ± 14.6 years) undergoing VTSA were prospectively included. Bipolar EGMs with &gt;3 deflections and duration &lt;133 ms were considered as potential HSC-EGM, if located within/surrounding the scar area. Whenever a potential HSC-EGM was identified, a double ventricular extrastimulus was delivered. If a local potential showed up as a delayed component, it was annotated as HSC-EGM. The incidence of HSC-EGM in core, border-zone, and normal-voltage regions was determined. Ablation was delivered at conducting channel entrances and HSC-EGMs. Procedure time, radiofrequency time, VT inducibility after VTSA and VT recurrence at 12 months after the procedure were compared with data from a historic control group (n = 66, 70% ischaemic, 65.2 ± 12 years). Results 5076 EGMs were analyzed. 1029 (20.2%) qualified as potential HSC-EGM, and 453 of them were tagged as HSC-EGMs. Scars in patients with HSC-EGMs (n = 43, 61.4%) were smaller (39.66 ± 28.2 vs 69.4 ± 38.2 cm2; p = 0.005) and more heterogeneous (core/scar area ratio 0.24 ± 0.2 vs 0.43 ± 0.17; p = 0.03). 29.6% of HSC-EGMs were located in normal-voltage tissue; 83.5% were targeted for ablation. Patients undergoing VTSA incorporating HSC analysis needed less procedure time (213 ± 75 vs 242 ± 60 min; p = 0.018), less RF time (15.9 ± 10 vs 25 ± 12,7 minutes; p &lt; 0.001), had a lower rate of VT inducibility (27.5% vs 51.5%; p = 0.005) and a higher 2-year VT/VF-free survival (82.8% vs 59.7%; log rank p = 0.047) after VTSA than the historic controls . Conclusion VTSA incorporating HSC analysis allowed further arrhythmic substrate identification (especially in normal-voltage areas) and resulted in increased  VTSA efficiency and better short and long-term outcomes.

Abstract Background: Rectal amputation (RA) remains an important surgical procedure for salvage despite advances in sphincter-preserving resection, including intersphincteric resection. The aim of this study was to compare short- and long-term outcomes of RA with an initial perineal approach to those of RA with an initial abdominal approach (conventional abdominoperineal resection (APR)) for primary anorectal cancer. Methods: We retrospectively analyzed the short- and long-term outcomes of 48 patients who underwent RA with an initial perineal approach (perineal group) and 21 patients who underwent RA with an initial abdominal approach (conventional group). Results: For the perineal group, the operation time was shorter than that for the conventional group (313 vs. 388 minutes, p = 0.027). The postoperative complication rate was similar between the two groups (43.8 vs. 47.6%, p = 0.766). Perineal wound complications (PWCs) were significantly fewer in the perineal group than in the conventional group (22.9 vs. 57.1%, p = 0.006). All 69 patients underwent complete TME, but positive CRM was significantly higher in the conventional group than in the perineal group (0 vs. 19.0%, p = 0.011). There were no significant differences in the recurrence (43.8 vs. 47.6%, p = 0.689), 5-year disease-free survival (63.7% vs. 56.7%, p = 0.665) and 5-year overall survival rates (82.5% vs. 66.2%, p = 0.323) between the two groups. Conclusion: These data suggest that RA with an initial perineal approach for selective primary anorectal carcinoma is advantageous in minimizing PWCs and positive CRMs. Further investigations on the advantages of this approach are necessary.

Abstract Background High body mass index (BMI) is thought to be a preoperative risk factor for surgical treatment. Until now, few studies have investigated the long-term impact of preoperative high BMI on advanced gastric cancer (GC) patients who underwent laparoscopic gastrectomy (LG). Therefore, the present study was designed to compare clinical outcomes between high BMI and normal BMI patients who underwent LG. MethodsWe retrospectively investigated 282 pathological stage II~III GC cases who underwent radical LG plus D2 lymphadenectomy from February 2009 to May 2018. Based on the China BMI classification, the patients were classified into a high (BMI ≥ 24 kg/m2) or normal (BMI < 24 kg/m2) BMI group. The clinical characteristics, intraoperative findings, short-term and long-term outcomes of the two groups of patients were then compared. Results The high BMI group had longer operation time (160.1 ± 36.0 minutes vs. 147.7 ± 33.7 minutes; P = 0.005) and greater intraoperative bleeding (138.3 ± 239.4ml vs. 86.6 ± 67.7ml; P = 0.002) compared to the normal BMI group. Moreover, shorter time to flatus, starting the soft diet, removing drain tube and length of stay (all P < 0.05) were observed in the high BMI patients. However, there was no significant difference in relapse-free survival or overall survival between the two groups. Conclusion Patients with high BMI was associated with longer operation time and greater amount of intraoperative bleeding but had faster recovery as compared to those with normal BMI. Also, LG can be considered as safe with no significant difference in terms of short- and long-term outcomes on the peri- and post-operative outcomes between the two BMI groups of patients. Nevertheless, these surgeries for high BMI patients should be performed by experienced surgeons.

Objectives: Carotid artery endarterectomy (CEA) and carotid artery stenting (CAS) are 2 effective treatment options for carotid revascularization and stroke prevention. The long-term outcomes of Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) reported similar stroke and death rate between the 2 procedures. This study presents the short- and long-term outcomes of CEA and CAS of all risk patients performed by a single vascular surgeon in a real-world setting. Methods: We retrospectively reviewed all patients who underwent CEA and CAS from September 2005 to June 2017 at our institute. Student t test, χ2, and Fisher exact tests were used to compare patient’s characteristics. Multivariate logistic, cox regression models and survival analysis were used to compare postoperative and long-term outcomes between the 2 groups. Results: Over 2000 patients were evaluated for carotid artery stenosis during the study period, and 313 revascularization procedures were performed (CEA: 47%, CAS: 53%). Patients’ age (Mean [95% confidence interval, CI] 68.8 [67.2-70.4] vs 69.7 [68.2-71.3], P = .40) was similar between CEA and CAS. Patients who underwent CAS had significantly higher comorbidities (chronic obstructive pulmonary disease [COPD], chronic heart failure [CHF], hyperlipidemia, and prior ipsilateral intervention, all P < .05). No difference was found in 30-day complications after CEA versus CAS including stroke (2.0% vs 1.2%), myocardial infarction (MI; 0.7% vs 1.2%), death (0% vs 1.2%) as well as combined major adverse events (stroke/death/MI; 2.7% vs 3.0%; all P > .05). Overall 7-year survival, stroke-free survival and restenosis-free survival were similar between the 2 groups ( P > .5). Significant predictors of mortality were diabetes (hazard ratio, HR [95% CI]: 2.41 [1.15-5.08]), chronic kidney disease (HR [95% CI]: 4.89 [1.97-12.13]), and COPD (HR [95% CI]: 3.31 [1.43-7.71]; all P values <.05). Statin use was protective with 71% reduction in risk of mortality (HR [95% CI]: 0.29 [0.12-0.67], P = .004). Conclusion: Our experience showed comparable short- and long-term outcomes of CAS and CEA performed for carotid artery stenosis by vascular surgeon. There was no difference between single institutional long-term outcomes and CREST outcomes following CEA and CAS.

Abstract Background Transanal total mesorectal excision (TaTME) for mid and low rectal cancer has been shown to improve short-term outcomes, mostly due to lower conversion rates and with improved quality of the specimen. However, robust long-term oncological data supporting the encouraging clinical and pathological outcomes are lacking. Methods All consecutive patients undergoing TaTME with curative intent for mid or low rectal cancer in two referral centers in The Netherlands between January 2012 and April 2016 with a complete and minimum follow-up of 36 months were included. The primary outcome was local recurrence rate. Secondary outcomes were disease-free survival, overall survival and development of metastasis. Results There were 159 consecutive patients. Their mean age was 66.9 (10.2) years and 66.7% of all patients were men. Pathological analysis showed a complete mesorectum in 139 patients (87.4%), nearly complete in 16 (10.1%) and an incomplete mesorectum in 4 (2.5%). There was involvement of the CRM (< 1 mm) in one patient (0.6%) and no patients had involvement of the distal margin (< 5 mm). Final postoperative staging after neoadjuvant therapy was stage 0 in 11 patients (6.9%), stage I in 73 (45.9%), stage II in 31 (19.5%), stage III in 37 (23.3%) and stage IV in 7 (4.4%). The 3-year local recurrence rate was 2.0% and the 5-year local recurrence rate was 4.0%. Median time to local recurrence was 19.2 months. Distant metastases were found in 22 (13.8%) patients and were diagnosed after a median of 6.9 months (range 1.1–50.4) months. Disease-free survival was 92% at 3 years and 81% at 5 years. Overall survival was 83.6% at 3 years and 77.3% at 5 years. Conclusions The long-term follow-up of the current cohort confirms the oncological safety and feasibility of TaTME in two high volume referral centers for rectal carcinoma. However, further robust and audited data must confirm current findings before widespread implementation of TaTME.

Introduction: Currently, there is limited data regarding the long-term outcomes of single incision laparoscopic surgery (SILS) for colon cancer. Therefore, we investigated both the short- and long-term outcomes of SILS for right-sided colon cancer. Methods: We retrospectively compared the short- and long-term outcomes of SILS and conventional laparoscopic surgery (CLS) for right-sided colon cancer (specifically the cecum and ascending colon) in our institution. Inter-group differences of short-term outcomes were evaluated using the chi-squared or Fisher exact test and two-sample Student’s t-test. The disease-free survival rates (long-term outcome) of stage 0 to III patients were estimated using the Kaplan–Meier method and compared using log-rank tests. Results: There were 290 operations conducted for right-sided (cecum and ascending color) colorectal cancers between April 2011 and July 2018. Twelve patients underwent planned laparotomy. Of the remaining 278 patients, 55 underwent planned conventional laparoscopic surgery, 27 patients had planned reduced poet surgery (RPS), and 196 patients had planned SILS. The procedures had been selected by skilled surgeons. One patient underwent intraoperative conversion from SILS to laparotomy for bleeding control. In addition, one port was added to SILS in three cases. These four cases were included in the analysis as the SILS group, according to the principle of intent to treat. Background factors, including age, sex, body mass index, performance status, and tumor stage were not statistically different between the SILS and CLS groups. In the short-term outcomes, the number of harvested lymph-nodes was not statistically different. SILS required less operating time (P<0.001) and resulted in a reduced bleeding volume (P<0.001). There was no statistical difference in the frequency of overall complications (P=0.06). The disease-free survival of stage 0 to III patients was not statistically different between the two groups. Conclusions: Skilled surgeons can achieve adequate oncologic long-term outcomes in selected subgroups of SILS patients. Therefore, SILS could be a treatment option for right-sided colon cancer.

Abstract Background The aim of this study was to investigate the prognostic significance of the prognostic nutritional index (PNI) for both short and long term outcomes after liver resection for hepatocellular carcinoma (HCC). Methods 162 (without any previous treatment) of 229 surgically treated HCC patients were retrospectively analyzed. The cut off value of the preoperative PNI was 45.0. Patients were divided into two groups, PNI low (n=76) and high (n=86) group. Results Among some immune parameters such as PNI, neutrophil to lymphocyte ratio (NLR) and aspartate aminotransferase (AST) to lymphocyte ratio (ALRI), PNI had most reliable parameters in terms with prediction of both short and long term outcomes. Preoperative PNI tended to correlate with low skeletal muscle mass (SMM). In short term outcomes, PNI low group were more likely to have postoperative complications. The disease-free survival rate in PNI low group was significantly worse than that in the PNI high group (20.5 vs. 48.7 %, 5 year SR, p=0.03). On multivariate analysis, Low PNI was an independent prognostic factor for disease free survival (HR 1.65, p= 0.04). Conclusions The preoperative PNI was the most significant prognostic factor for evaluating both short and long-term outcomes after liver resection for HCC.
