Reply to “Nodal skip metastasis may undermine the predictive power of topographic pN classification in esophageal squamous cell carcinoma”
We appreciate the comments made by Yang et al1 regarding our recent article.2 They obtained results consistent with ours using their own cohort and reported a lower survival discriminatory ability of topographic nodal classification, especially between JES-pN2 and JES-pN3 patients compared with the numeric classification system. The 2 cohorts are distinctly different in terms of the proportions of advanced stage esophageal squamous cell carcinoma (ESCC) patients, and therefore the superiority of numeric-based pN classification versus the topographic-based system might be accepted regardless of the ESCC cohort.

Robotic surgery or enhanced recovery programs or both? And in which order?
The last few decades have seen 2 major innovations in our surgical practice. One is both technical and organizational —enhanced recovery after surgery (ERAS)1; the other is technological—robotic surgery.2 These 2 innovations, each in their own way, were designed to mitigate surgical aggression and improve postoperative outcomes: robotic surgery by its minimal invasiveness and ERAS by medical and surgical periop erative measures. Rather than opting for either one or the other, it might be more judicious to use them synergistically. (Source: Surgery)

Perioperative use of cefazolin without preliminary skin testing in patients with reported penicillin allergy
We read with great interest the report by Moussa et al1 on delabeling β-lactam allergy in the perioperative setting, given the benefits with respect to appropriate antibiotic selection, decreased surgical delays, and decreased surgical site infection rates. We recognize that penicillin skin testing (PST) and oral challenge is the most effective means of β-lactam all ergy verification. However, expedient access to comprehensive allergy evaluation may not be feasible at most institutions given the personnel, training, time, and required materials for PST. (Source: Surgery)

Global surgical, obstetric, and anesthetic task shifting: A systematic literature review
Five billion people lack access to safe, affordable, and timely surgical care; this is in part driven by severe shortages in the global surgical workforce.

Impact of a resident's sex on intraoperative entrustment of surgery trainees
Optimizing intraoperative education is critical for development of autonomous residents. Faculty decisions concerning intraoperative entrustment determine the degree to which a resident gains intraoperative responsibility. Accordingly, residents exhibit entrustable behaviors that further faculty entrustment in the operating room. Little empiric evidence exists evaluating how the sex of a resident influences faculty-resident decisions of entrustment. Studies involving perception-based measurements of autonomy report inequities for women residents. (Source: Surgery)

Databases for surgical health services research: Veterans Affairs Surgical Quality Improvement Program
In the mid-1980s, the United States Congress passed legislation that created a statutory mandate for Veterans Affairs (VA) to develop a system to evaluate the quality of care provided to veterans in VA hospitals; patient outcomes should be compared to the national average, and the data should include risk adjustment.1 The VA began tracking risk-adjusted outcomes after cardiac surgery in 1987 through the Continuous Improvement in Cardiac Surgery Study.2 A similar model was then applied to initiate the National VA Surgical Risk Study for noncardiac surgery.

Joint Statement by the Surgery Journal Editors Group* 2018
We, the editors of surgery journals, believe that conducting sex-inclusive biomedical and clinical research is imperative to improving health outcomes of men and women. Note that we use the word “sex” and not “gender.” Sex is the genotype by which one is born, and gender is the phenotype. It is the chromosomal sex of the human, animal, tissue, or cell to which we are referring. Recent studies have shown that the majority of biomedical research in the field of surgery and related top ics is conducted on male animals and male cells, even when studying diseases prevalent in women.

Opportunistic salpingectomy to decrease the mortality from ovarian cancer: Can we expand the pool of eligible patients?
The focus on what anatomic site is most responsible for development of ovarian cancers has shifted specifically from the ovary to the fallopian tube. Nearly 2 decades ago, gynecologic pathologists first noticed the presence of early serous adenocarcinomas in the fallopian tubes of woman undergoing risk-reducing bilateral salpingo-oophorectomy for deleterious BRCA1/2 mutations, mutations that markedly increase the risk of developing ovarian cancer. Since that time, great attention has been paid to the fallopian tube as the origin of serous ovarian and pelvic carcinomas, and pathologic evaluation of the fallopian tube has ev...
