Introdcution Although nipple sparing mastectomy (NSM) has attracted increased recognition as an alternative to traditional mastectomy approaches, its oncological safety is unclear. The purpose of this study was to compare the local recurrence rate between NSM and total mastectomy (TM). Methods Between 2003 and 2013, 121 and 557 patients with stage 0–III breast cancer underwent NSM and TM respectively. Multivariate Cox regression and propensity score models were used to compare the two groups. Results There was no significant difference in the five-year local recurrence rate between the NSM and TM groups (7.6% vs 4.9%, p=0.398). In multivariate analysis, NSM was not a risk factor for local recurrence (hazard ratio: 1.653, 95% confidence interval: 0.586–4.663, p=0.343). Propensity score matching found similar five-year local recurrence free survival rates between the two groups (92.3% vs 93.7%, p=0.655). Conclusions Our results suggest that NSM may provide oncological safety comparable with mastectomy for carefully selected patients.

Background Cold polypectomy has been increasingly used to remove diminutive colorectal polyps. We evaluated the local recurrence rate of diminutive polyps at the 1-year follow-up after cold forceps polypectomy (CFP). Methods In a prospective, multicenter, observational cohort study, patients with diminutive colorectal polyps ( ≤ 5 mm) were treated by CFP using jumbo forceps followed by magnified narrow-band imaging (NBI). Patients were assessed for local recurrence at 1-year follow-up. Risk factors associated with local recurrence were analyzed using logistic regression analysis. Results Overall, 955 lesions were resected in 471 patients who completed the 1-year follow-up. The endoscopic complete resection rate was 99.4 %. Immediate and delayed bleeding occurred in 0.8 % and 0.2 % of cases, respectively, with no perforations observed. Local recurrence occurred in 2.1 % of cases at the 1-year follow-up. Univariable analyses indicated that polyps > 3 mm (P < 0.01) and immediate bleeding (P = 0.04) were significantly associated with local recurrence. A trend was observed for patients ≥ 65 years (P = 0.06) and fractional resection (P = 0.09). Multivariable analyses confirmed that lesions > 3 mm were significantly associated with local recurrence (odds ratio 3.4, P = 0.02). Conclusions CFP with jumbo forceps followed by NBI-magnified observation had a low local recurrence rate and is an acceptable therapeutic option for diminutive colorectal polyps. Although we recommend limiting the use of CFP with jumbo forceps to polyps ≤ 3 mm in size, future comparative studies are needed to make recommendations on cold polypectomy using either forceps or snares as the preferred approach for diminutive polyp resection.

Introduction: There are no randomized controlled trials that compared the outcomes of leadless pacemaker (L-PPM) implantation with transvenous pacemaker (TV-PPM) and there is scarcity of data on real world outcomes. Methods: We queried National Inpatient Sample to identify all adult patients who had primary discharge diagnosis of conduction disorders or tachy-arrhythmias and excluded patients who had a concomitant procedure for valve replacement, coronary artery bypass grafting, ablation and/or cardiac implantable electronic device removal so that complications can be attributed to the pacemaker implantation. We included only procedures from November 2016 to December 2017 as Micra was the only available L-PPM during that period. For the comparison cohort we selected patients, during the same time period, who had a procedure code for single chamber pacemaker implantation in conjunction with right ventricular lead placement. We performed 1:1 propensity score matching and the variables used for matching are marked with asterisk in Table 1. All the codes used to identify complications has been previously validated from the Micra Post-approval registry and Coverage with Evidence Study. Results: Total of 1,305 patients for L-PPM and 13,905 patients in the TV-PPM group were included. Baseline characteristics with standardized mean difference before and after matching are shown in Table 1. Briefly, patients in L-PPM group were younger but had higher co-morbidities compared to TV-PPM group. The complications before and after matching are shown in Table 2. Conclusions: In conclusion, we found no significant difference between in-hospital complications after propensity score matching, with the exception of deep venous thrombosis. There was no difference between length of stay but cost for L-PPM was significantly higher. In this real-world analysis, we found that the leadless PPM implantation is safe in comparison to transvenous PPM.

Abstract Background and study aims Cold snare polypectomy (CSP) for small colorectal polyps has lower incidence of adverse events, especially delayed postpolypectomy bleeding (DPPB). However, few data are available on comparisons of the incidence of DPPB of CSP and hot polypectomy (HP). The aim of this study was to evaluate the incidence of DPPB after CSP and compare it with that of HP. A propensity score model was used as a secondary analysis. Patients and methods This was a retrospective cohort study conducted in a single municipal hospital. We identified 539 patients with colorectal polyps from 2 mm to 11 mm in size who underwent CSP (804 polyps in 330 patients) or HP (530 polyps in 209 patients) between July 2013 and June 2015. Results There were no cases of DPPB in the CSP group. Conversely, DPPB occurred in 4 patients (1.9 %) after HP, resulting in a significant difference between the CSP and HP groups (0.008 % vs 0 %, P = 0.02). Propensity score-matching analysis created 402 matched pairs, yielding a significantly higher DPPB rate in the HP group than CSP group (0.02 % vs 0 %, P = 0.04). However, significantly more patients in the CSP group had unclear horizontal margins that precluded assessment (83 vs 38 cases, P < 0.001). The retrieval failure rate was significantly higher in the CSP group than in the HP group (3 % vs 0.7 %, P = 0.01). Conclusions DPPB was less frequent with CSP than HP, as selected by the propensity score-matching model. Our findings indicate that CSP is recommended polypectomy in daily clinical setting. However, special care should be taken during polyp retrieval and horizontal margin assessment, and these issues could be taken into account in follow-up after CSP.
