BACKGROUND: There is evidence that neoadjuvant therapy is associated with improved survival compared with upfront pancreatectomy for pancreatic adenocarcinoma. Treatment at high-volume pancreatic surgery centers is associated with improved short-term postoperative outcomes compared with low-volume centers. We compared overall survival of patients with early-stage pancreatic adenocarcinoma who received neoadjuvant therapy before resection stratified by facility volume. METHODS: Patients with clinical T0 to T2 pancreatic adenocarcinoma who received neoadjuvant therapy before pancreatoduodenectomy were identified in the National Cancer Database (2010-2016)...

BACKGROUND: Complex abdominal wall reconstruction using biologic mesh can lead to increased recurrence rates, nonincorporation, and high perioperative costs. We developed a novel decellularization method and applied it to porcine muscle fascia to mirror target-tissue architecture. The aims of this study were to analyze mechanical strength and tissue-graft incorporation. METHODS: After serial decellularization, muscle-fascia mesh was created and tested for mechanical strength and DNA content...

BACKGROUND: Trauma patients may present with nonsurvivable injuries, which could be resuscitated for future organ transplantation. Trauma surgeons face an ethical dilemma of deciding whether, when, and how to resuscitate a patient who will not directly benefit from it. As there are no established guidelines to follow, we aim to describe resuscitation practices for organ transplantation; we hypothesize that resuscitation practices vary regionally. METHOD: Over a 3-month period, we surveyed trauma surgeons practicing in Levels I and II trauma centers within a single state using an instrument to measure resuscitation attitudes and practices for organ preservation...

Patients and physicians make essential decisions regarding diagnostic and therapeutic interventions. These actions should be performed or deferred under time constraints and uncertainty regarding patients' diagnoses and predicted response to treatment. This may lead to cognitive and judgment errors. Reinforcement learning is a subfield of machine learning that identifies a sequence of actions to increase the probability of achieving a predetermined goal. Reinforcement learning has the potential to assist in surgical decision making by recommending actions at predefined intervals and its ability to utilize complex input data, including text, image, and temporal data, in the decision-making process...

BACKGROUND: Nutritional status and tumor markers are important prognostic indicators for surgical decisions in pancreatic carcinoma. This study aimed to stratify the probability of surviving pancreatic carcinoma based on systematically chosen nonanatomic biomarkers. METHODS: We included 187 consecutive patients that underwent surgical resections for pancreatic carcinoma. We performed multivariable analyses to evaluate prognostic indicators, including 4 blood-test indexes: the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, prognostic nutritional index, and the modified Glasgow prognostic score; and 4 body-composition indexes: the normalized total psoas muscle area, the normalized total elector spine muscle area, the psoas muscle computed tomography value, and the elector spine muscle computed tomography value...

BACKGROUND: Reduced creatinine clearance is an indication for surgery in asymptomatic primary hyperparathyroidism, and a significant proportion of patients undergoing parathyroidectomy have chronic kidney disease. The purpose of this study was to evaluate the kinetics of intraoperative parathyroid hormone decline during parathyroidectomy in patients who have chronic kidney disease compared with those with who have normal renal function. METHODS: This is a single-center, retrospective study of patients with primary hyperparathyroidism undergoing parathyroidectomy (n = 646)...

BACKGROUND: Incisional hernias represent an acquired defect from failed healing of an abdominal facial incision and are therefore distinct from primary hernias. While literature regarding incisional hernia incidence, risk factors, and treatment are abundant, no study has examined national health disparities specific to incisional hernia repair. The objective of this study was to analyze national health disparities unique to surgical incisional hernia repair procedures. METHODS: Patient data queried from the Healthcare Cost and Utilization Project National Inpatient Sample from 2012 to 2014 using International Classification of Diseases 9th revision procedure codes for incisional hernia repair were used to generate univariate and multivariate models including demographics, socioeconomic factors, admission status, and hospital characteristics...

BACKGROUND: Long-term ex situ liver perfusion may rescue injured grafts. Little is known about bile flow during long-term perfusion. We report the development of a bile stimulation protocol and motivate bile flow as a viability marker during long-term ex situ liver perfusion. METHODS: Porcine and human livers were perfused with blood at close to physiologic conditions. Our perfusion protocol was established during phase 1 with porcine livers (n = 23). Taurocholic acid was applied to stimulate bile flow...

BACKGROUND: Previous data has shown that severe traumatic injury is associated with bone marrow dysfunction, which manifests as persistent injury-associated anemia. This study sought to identify whether the expression of erythropoiesis-related microRNAs were altered in the bone marrow of trauma patients to determine if these microRNAs play a role in persistent injury-associated anemia. METHODS: Bone marrow was collected from severely injured trauma patients who underwent fracture fixation as well as patients who underwent elective hip replacement...

There is a growing interest in using machine learning algorithms to support surgical care, diagnostics, and public health surveillance in low- and middle-income countries. From our own experience and the literature, we share several lessons for developing such models in settings where the data necessary for algorithm training and implementation is a limited resource. First, the training cohort should be as similar as possible to the population of interest, and recalibration can be used to improve risk estimates when a model is transported to a new context...

BACKGROUND: As the opioid crisis continues, it is critical that health care providers ensure they are not overprescribing opioid medications. At our institution (Walter Reed National Military Medical Center, Bethesda, MD), postoperative patients after breast surgeries are discharged with variable amounts of opioid medications. However, many patients report minimal opioid use. The objectives of this study were to characterize postoperative opioid usage and prescribing practices for patients undergoing various breast surgeries and to recommend the number of opioid pills for discharge for each procedure...
