A novel method for lymphadenectomy along the left laryngeal recurrent nerve during thoracoscopic esophagectomy for esophageal carcinoma

Background

Due to limited space in the left upper mediastinum, complete dissection of lymph nodes (LN) along left recurrent laryngeal nerve (RLN) is difficult. We herein present a novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position for esophageal carcinoma. The method, suspension the esophagus and push aside trachea, allows en bloc lymphadenectomy along the left RLN from the below aortic arch to the thoracic inlet.

Methods

Between September 2014 and September 2015, a total of 110 consecutive patients with esophageal carcinoma were treated with thoraco-laparoscopic esophagectomy with cervical anastomosis in the semi-prone position. Outcomes between those who received surgery with the novel method and conventional surgery were compared.

Results

Fifty patients underwent the novel method and sixty received conventional surgery. The operative field around the left RLN was easier to explore with the novel method. The estimated blood loss was less (23.7±8.2 vs. 34.2±10.3 g, P=0.001), and the number of harvested LNs along the left RLN was greater (6.4±3.2 vs. 4.1±2.8 min, P=0.028) in the novel method group, while the duration of lymphadenectomy along left RLN was longer in the novel method group (28.2±3.9 vs. 20.3±2.8 min, P=0.005). The rate of hoarseness in the novel and conventional groups was 10% and 16.7%, respectively. No significant difference in postoperative morbidity related to the left RLN was noted between the groups.

Conclusions

The novel method during semi-prone esophagectomy for esophageal carcinoma is associated with better surgeon ergonomics and operative exposure.     

Hemoglobin A1c,frequency of glucose testing and social disadvantage: Metrics of racial health disparity in youth with type 1 diabetes

Introduction

Black youth with type 1 diabetes (T1D) have higher HbA1c than whites. To understand HbA1c differences, we examined the relationship of psycho-social factors and glucose testing with HbA1c.

IFCC参考方法对两种常规检测系统ALP结果正确度的验证

目的评价常规检测系统测定血清碱性磷酸酶(ALP)的正确度。方法以国际临床化学联合会(IFCC)参考方法和两种常规检测系统(简称A法、B法)同时测定20份新鲜单人份血清样品。按美国临床实验室标准化协会(CLSI)EP9-A2文件评价两种常规检测系统测定结果的正确度,并用改良Bland-Altman图形分析法进行验证,评价常规检测系统与参考方法测定结果的一致性,综合判断常规检测系统的测定结果。按CLSI EP14-A2文件评价A、B两种方法校准品的基质效应。结果 A法、B法与IFCC参考方法测定结果的直线回归方程分别为YA=0.982 9XIFCC+0.010 8,YB=0.938 3XIFCC+0.012 9,平均偏倚分别为-1.1%、-5.5%。A法和B法检测结果的相关方程为YB=0.955 2XA+0.001 36,R2=0.997 6。A法和B法的校准品均存在基质效应,其中A法校准品的基质效应更明显。结论 A法与IFCC参考方法正确度性能一致,B法与IFCC参考方法正确度性能不一致。

Does clinical experience affect the reproducibility of cervical vertebrae maturation method?

Objective:To assess interobserver and intraobserver reproducibility of the cervical vertebrae maturation method (CVMM) among three panels of judges with different levels of orthodontic experience (OE).Materials and Methods:Fifty individual lateral cephalograms of good quality with complete visualization of cervical vertebrae 1 to 4 were selected. Thirty clinicians, divided according to their OE into three groups (junior group, JU, OE ≤ 1 year; postgraduate group, PG, 2 ≤ OE ≤ 4 years; specialist group, SP, OE ≥ 7 years), evaluated the cephalograms in two sessions (T₁ and T₂) at 3 weeks apart. Kendall''s W and weighted Cohen''s kappa (κ) coefficients were performed to assess interobserver and intraobserver agreement. The level of significance was set as P < .05. For both the interobserver and the intraobserver datasets, the percentage of perfect agreement (PPA) and the number of stages apart for each disagreement were calculated.Results:Kendall''s W at T₁ was SP  =  0.61, PG  =  0.70, and JU  =  0.87; at T₂ it was SP  =  0.78, PG  =  0.85, and JU  =  0.86. The percentage of total interobserver perfect agreement (Inter-PPA) was 42.3% at T₁ and 46.3% at T₂. The JU group had the highest Cohen''s κ coefficient at 0.78, while the PG and SP had coefficients of 0.64 each. The percentage of total intraobserver perfect agreement (Intra-PPA) was 54.2%.Conclusions:The reproducibility of the method was not improved by the level of orthodontic experience. The group with the lowest level of orthodontic experience had the best performance.
