Abstract Purpose A defunctioning stoma reduces the risk of symptomatic anastomotic leakage after low anterior resection for rectal cancer and mitigates the consequences when a leakage occurs, but the impact on mortality and oncological outcomes is unclear. The aim was to investigate the associations of a defunctioning stoma with short- and long-term outcomes in patients undergoing low anterior resection for rectal cancer. Methods Data from all patients who underwent curative low anterior resection for rectal cancer between 1995 and 2010 were obtained from the Swedish Colorectal Cancer Register. A total of 4130 patients, including 2563 with and 1567 without a defunctioning stoma, were studied. Flexible parametric models were used to estimate hazard ratios for all-cause mortality, 5-year local recurrence, and distant metastatic disease in relation to the use of defunctioning stoma, adjusting for confounding factors and accounting for potential time-dependent effects. Results During a median follow-up of 8.3 years, a total of 2169 patients died. In multivariable analysis, a relative reduction in mortality was observed up to 6 months after surgery (hazard ratio = 0.82: 95% CI 0.67–0.99), but not thereafter. After 5 years of follow-up, 4.2% (173/4130) of the patients had a local recurrence registered and 17.9% (741/4130) had developed distant metastatic disease, without difference between patients with and without defunctioning stoma. Conclusion A defunctioning stoma is associated with a short-term reduction in all-cause mortality in patients undergoing low anterior resection for rectal cancer without any difference in long-term mortality and oncological outcomes, and should be considered as standard of care.

Abstract BackgroundThere is uncertainty in the literature about the best surgical approach for low anterior resection of rectal cancer to deal with the inferior mesenteric artery (IMA), that is to preserve left colic artery or not. We analyzed the effect of preserving the left colic artery (LCA) on long-term oncological outcomes. MethodsWe retrospectively collected clinicopathological and follow-up details of patients who underwent low anterior resection for rectal cancer in the General Surgery Department of Guangdong Provincial People's Hospital, from January 2014 to December 2015. Cases were divided into low ligation (LL) or high ligation (HL) of the IMA The 5-year overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. ResultsAltogether, there were 221 cases in the LL group (LCA preserved) and 295 cases in the HL group (LCA not preserved). Postoperative 30-day mortality was 0.9% in the LL group and 1.4% in the HL group. Early complications occurred in 41.2% patients in the LL group and 38.3% in the HL group. Anastomotic leakage occurred in 8.6% of patients in the LL group and in 13.2% in the HL group. The numbers of lymph nodes harvested were 18.8 ± 9.6 in the LL group and 17.0 ± 6.6 in the HL group. The median follow-up periods were 51.4 (7–61) months in the LL group and 51.2 (8–61) months in the HL group. During follow-up, the percentages of patients who died, had local recurrence, or had metastases were 39.8%, 7.7%, and 38.5%, respectively, in the LL group and 39%, 8.5%, and 40%, respectively, in the HL group; these differences were not significant (all P ＞ 0.05). The 5-year OS and DFS were 69.6% and 59.6% in the LL group, respectively, and 60.1% and 56.2% in the HL group, respectively; these differences were not significant (all P ＞ 0.05). After stratification by tumor-node-metastasis stage, the difference between the 5-year OS and DFS for stages I, II, and III cancer were not significant (all P ＞ 0.05). ConclusionsThe long-term oncological outcomes of low anterior resection for rectal cancer with preservation of the LCA are comparable with those of ligation at the IMA origin.

Abstract Background There is uncertainty in the literature about preserving the left colic artery (LCA) during low anterior resection for rectal cancer. We analyzed the effect of preserving the LCA on long-term oncological outcomes. Methods We retrospectively collected clinicopathological and follow-up details of patients who underwent low anterior resection for rectal cancer in the General Surgery Department of Guangdong Provincial People’s Hospital, from January 2014 to December 2015. Cases were divided into low ligation (LL), LCA preserved, or high ligation (HL), LCA not preserved, of the inferior mesenteric artery. The 5-year overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. Results Altogether, there were 221 and 295 cases in the LL group and HL groups, respectively. Operating time in the LL group was significantly longer than in the HL group (224.7 vs. 211.7 min, p = 0.039). Postoperative 30-day mortality, early complications including anastomotic leakage showed no significant differences between the LL and HL groups (postoperative 30-day mortality, 0.9% LL, 1.4% HL, p = 0.884; early complications, 41.2% LL, 38.3% HL, p = 0.509; anastomotic leakage 8.6% LL, 13.2% HL, p = 0.100). The median follow-up periods were 51.4 (7–61) months in the LL group and 51.2 (8–61) months in the HL group. During follow-up, the percentages of patients who died, had local recurrence, or had metastases were 39.8, 7.7, and 38.5%, respectively, in the LL group and 39, 8.5, and 40%, respectively, in the HL group; these differences were not significant (all p > 0.05). The 5-year OS and DFS were 69.6 and 59.6% in the LL group, respectively, and 69.1 and 56.2% in the HL group, respectively; these differences were not significant (all p > 0.05). After stratification by tumor-node-metastasis stage, the difference between the 5-year OS and DFS for stages I, II, and III cancer were not significant (all p > 0.05). Conclusions The long-term oncological outcomes of LL group are comparable with HL group. LL cannot be supported due to the absence of lower complication rates and the longer operating times.

Abstract Background: This study aimed to evaluate the short- and long-term outcomes after laparoscopic resection for low rectal cancer (LRC) compared with mid/high rectal cancer (M/HRC). Methods: Patients with rectal cancer undergoing laparoscopic resection with curative intent were retrospectively reviewed between 2009 and 2015. After matched 1:1 by using propensity score analysis, perioperative and oncological outcomes were compared between LRC and M/HRC groups. Multivariate analysis was performed to identify independent factors of overall survival (OS) and disease-free survival (DFS). Results: Of 373 patients who met the criteria for inclusion, 260 patients were matched for the analysis. Laparoscopic surgery for LRC required longer operative time (P＜0.001) and more blood loss volume (P＜0.001) compared with M/HRC, and the LRC group tended to have a higher incidence of postoperative complications (18.5% vs. 10.0%, P=0.051). There was no significant difference in local recurrence between the two groups (6.2% vs. 2.3%, P=0.216), whereas distant metastasis was more frequent in LRC patients compared with M/HRC (19.2% vs. 9.2%, P=0.021). The LRC group showed significantly inferior 5-year OS (78.1% vs. 88.8%, P=0.008) and DFS (76.2% vs. 89.0%, P=0.004) compared with the M/HRC group. Multivariate analysis indicated that tumor location was an independent predictor of OS (HR=2.095, 95% CI 1.142-3.843, P=0.017) and DFS (HR=2.320, 95% CI 1.251-4.303, P=0.008). Conclusion: Tumor location of the rectal cancer significantly affected the clinical and oncological outcomes after laparoscopic surgery, and it was an independent predictor of OS and DFS.

Abstract Introduction There is few data about long-term outcomes of conservative management (without catheter ablation) of patients with a first episode of arrhythmic storm (AS) in the current context. This study analyzes the short and long-term outcomes of implantable cardioverter defibrillator (ICD) patients with a first episode of AS receiving non-interventional management. Methods Consecutive patients admitted with a first episode of AS between January 2008 and June 2019 receiving medical management without catheter ablation were included. AS was defined as 3 or more appropriate ICD therapies occurring during a 24 h span. Medical management included: correction of triggers, sedation/mechanical ventilation, antiarrhythmic drugs, ICD reprogramming and neuraxial modulation. Baseline clinical characteristics and follow-up data were recorded. All patients were followed every 6 months at the ICD office. The primary end-point was all-cause mortality. Results 60 patients (81% male, 62.8±16.2 years, 43% ischaemic, LVEF 35.4±14%) with a first episode of AS treated conservatively were included. Thirty-day survival was 96.5% and 1-year survival was 82%. During a median (interquartilic range) follow-up of 31 (6–69) months, 31 (51.7%) patients died (51.6% due to cardiovascular aetiology) and 35 (58.3%) patients were readmitted (48.5% due to recurrent arrhythmic events and 45.7% due to heart failure). Age [HR 1.05 (95% confidence interval: 1.01–1.08)] and end-diastolic diameter [HR 1.05 (95% confidence interval: 1–2)] were the strongest independent predictors of all-cause mortality. Conclusion Despite the severity of this entity, medical management (without catheter ablation) of a first episode of AS is reasonable given its good 30-day and 1-year survival. However, a high rate of AS recurrence and readmissions are observed during long-term follow-up. Efforts are needed in order to identify those patients with a first episode of AS that could benefit from an early catheter ablation strategy. Funding Acknowledgement Type of funding source: None

Abstract Aim To analyze the effect of preserving the left colic artery (LCA) on long-term oncologic outcomes during laparoscopic low anterior resection of rectal cancer. Methods Clinicopathological and follow-up patients undergoing laparoscopic low anterior resection of rectal cancer in general surgery department of Guangdong Provincial People's Hospital from January 2014 to December 2015 were retrospectively collected. According to the difference surgical methods of inferior mesenteric artery (IMA), 159 cases were divided into the LCA preservation group and 225 cases in the LCA non-preservation group. The 5-year rates of overall survival (OS) and disease-free survival (DFS) were compared between two group. Results 384 patients were included in final analysis. Anastomotic leakage occurred in 7 patients (4.4%) in the LCA preservation group and in 16 patients (7.1%) in the LCA non-preservation group. The follow-up rate was 91.2% (145/159) during 5–60 months in LCA preservation group, and 89.8% (202/225) during 5–60 months in the LCA non-preservation group. The number of patients who developed death, local recurrence and metastasis were 59 (37.1%), 13 (8.2%) and 60 (37.7%) in the LCA preservation group, and 86 (38.2%), 20 (8.9%) and 92 (40.9%) in the LCA non-preservation group, without significant differences (all P ༞ 0.05). The 5-year OS and DFS rates were 69.0% and 59.3% in the LCA preservation group, and 68.8% and 55.9% in the LCA non-preservation group, without significant differences (all P ༞ 0.05). After stratification by TNM Stage, the difference on 5-year OS rates and DFS rates of I stage, II stage and III stage in two groups were no significant as well (all P ༞ 0.05). Conclusions The long-term oncologic outcomes of laparoscopic low anterior resection of rectal cancer with preservation of the LCA are comparable with ligation at origin of IMA.
