Minimally invasive pancreatoduodenectomy: is the incidence of clinically relevant postoperative pancreatic fistula comparable to that after open pancreatoduodenectomy?
Studies evaluating the efficacy of minimally invasive approaches to pancreatoduodenectomy (MIS-PD) compared to open pancreatioduodenectomy (OPD) have been limited by selection bias and mixed outcomes. (Source: Surgery)

Databases for surgical health services research: National cancer database
There has been growing attention to quality measurement in surgical oncology. The 1999 landmark publication “To Err is Human” by the Institute of Medicine brought widespread awareness to deficiencies in patient safety.1 In the same year, the Institute of Medicine reported substantial variation in quality of cancer care in “Ensuring Quality Cancer Care.”2 In the ensuing decades, the National Qualit y Forum launched a program to encourage development of cancer-specific quality measures and, in 2007, endorsed 5 quality measures developed in a joint effort between the American College of Surgeons Commis...

Systematic review, meta-analysis, and a high-volume center experience supporting the new role of mural nodules proposed by the updated 2017 international guidelines on IPMN of the pancreas
Mural nodules (MNs) have a predominant role in the 2016 revision of the international guidelines on intraductal papillary mucinous neoplasms (IPMN) of the pancreas. The aim of this study was to evaluate MNs as predictors of invasive cancer (iCa) or high-grade dysplasia (HGD) in IPMNs and to investigate the role of MN size in risk prediction. (Source: Surgery)

The value proposition of simulation-based education
Simulation has become an integral part of physician education, and abundant evidence confirms that simulation-based education improves learners' skills and behaviors and is associated with improved patient outcomes. The resources required to implement simulation-based education, however, have led some stakeholders to question the overall value proposition of simulation-based education. This paper summarizes the information from a special panel on this topic and defines research priorities for the field. (Source: Surgery)

Corrigendum to “Inhibition of Fgf signaling in short bowel syndrome increases weight loss and epithelial proliferation.” [surgery volume 161, number 3 (2017) 694–703]
We recently reviewed our manuscript and identified two errors: in Fig  2 Panel A, this should have reported the PCR data for erm to confirm the heatshock treatment resulted in decreasing downstream effectors of Fgf signaling. Additionally, the fgfr1 primers were not for qRT-PCR as reported. Expression of Fgfr1 downstream target, erm was examined by qRT-PCR instead. This does not change the fact that the heatshock model was successful or change the conclusions of the paper, but we would like to correct the record. (Source: Surgery)

Identifying the low risk patient in surgical intensive and intermediate care units using continuous monitoring
Continuous predictive monitoring has been employed successfully to predict subclinical adverse events. Should low values on these models, however, reassure us that a patient will not have an adverse outcome? Negative predictive values of such models could help predict safe patient discharge. The goal of this study was to validate the negative predictive value of an ensemble model for critical illness (using previously developed models for respiratory instability, hemorrhage, and sepsis) based on bedside monitoring data in the intensive care units and intermediate care unit.

A 57-year-old gentleman presented to clinic with a 6-month history of right upper quadrant abdominal pain. The pain was aggravated by respiration, movement, and lying on the right side. Patient denied any fever, weight loss, or gastrointestinal-related symptoms. The patient's medical history was notable for type 2 diabetes mellitus and hypertension controlled with medications. The patient's surgical history was unremarkable for trauma or previous surgery. Physical examination indicated right upper quadrant bulging and tenderness. (Source: Surgery)

Editorial: peptide receptor radionuclide therapy as neoadjuvant therapy for resectable or potentially resectable pancreatic neuroendocrine neoplasms
Peptide receptor radio therapy (PRRT) is a hot topic in the field of neuroendocrine tumor treatment. It has been available in Europe, where this report originated, for many years but not in the United States. I have been privileged to be an advisor to and part of a PRRT program in London for the past several years and have found that only a minute fraction of my American patients who might benefit from PRRT have had the resources to travel there repeatedly and pay privately for the several cycles of treatments.

Active surveillance for micro-papillary thyroid carcinoma: who are candidates, how should they be followed, when should they be treated, and what are the clinical and pathologic outcomes after delayed intervention
We read with interest the commentary by Shaha and Tuttle.1 Active surveillance (AS) is an established treatment option for patients with localized, low-risk papillary microcarcinoma (PMC). Utilization of AS for selected low-risk cancers is increasing as is considered appropriate for low-risk prostate cancer and on occasion in breast cancer and small renal neoplasms.2 AS entails the postponement of immediate therapy with the option of delayed intervention if or when the disease progresses. AS is required because of overdiagnosis, along with our inability to predict accurately individual PMC behavior. (Source: Surgery)

Re: Each procedure matters: threshold for surgeon volume to minimize complications and decrease cost associated with adrenalectomy
With interest, we read the article by Anderson et  al on the association of surgeon volume with minimizing complications and decreasing cost associated with adrenalectomy.1 The lack of clarity in the definition of a “high volume” surgeon led the authors to further address this issue. The authors sought to find the threshold annual surgeon volu me beyond which there is the least risk of complications. Surgeon volume was used as a continuous, nonlinear variable in logistic regression with restricted cubic splines to predict inpatient complications after adrenalectomy. (Source: Surgery)
