It is our view that the state of the art in constructing a large collection of graph algorithms in terms of linear algebraic operations is mature enough to support the emergence of a standard set of primitive building blocks. This paper is a position paper defining the problem and announcing our intention to launch an open effort to define this standard.
BACKGROUND Video-assisted thoracic surgical (VATS) lobectomies and wedge resections result in less morbidity and shorter length of stay than resections via thoracotomy. The impact of robot-assisted thoracic surgical (RATS) lobectomy on clinical and economic outcomes has not been examined. This study compared hospital costs and clinical outcomes for VATS(More)
BACKGROUND AND OBJECTIVES Laparoscopic colectomies, with and without robotic assistance, are performed to treat both benign and malignant colonic disease. This study compared clinical and economic outcomes for laparoscopic colectomy procedures with and without robotic assistance. METHODS Patients aged ≥18 years having primary inpatient laparoscopic(More)
AIMS To evaluate the real-world effect of laparoscopic bariatric surgery, comprising adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG), on the management of obesity-related comorbidities. METHODS Patients who underwent laparoscopic bariatric surgeries between 2006 and 2013 were(More)
OBJECTIVES The objective of this retrospective study was to quantify the clinical and economic burden of significant bleeding in lung resection surgery in the US. METHODS This study utilized 2009-2012 data from the Premier Perspective DatabaseTM. Adult patients with primary pulmonary lobectomy or segmentectomy procedures were categorized by the surgical(More)
Video-assisted thoracic surgery (VATS) research often focuses on postoperative air leak, with special consideration for prolonged air leak. There is limited clinical data regarding how stapling devices might affect performance and postoperative outcomes, including air leak. This prospective research evaluates intraoperative and postoperative data associated(More)
OBJECTIVES To determine hospital resource utilization, associated costs and the risk of complications during hospitalization for four types of surgical resections and to estimate the incremental burden among patients with cancer compared to those without cancer. METHODS Patients (≥18 years old) were identified from the Premier Research Database of US(More)
AIMS To compare economic and clinical outcomes between patients undergoing laparoscopic Roux-en-Y gastric bypass (LRY) or laparoscopic sleeve gastrectomy (LSG) with use of powered vs manual endoscopic surgical staplers. MATERIALS AND METHODS Patients (aged ≥21 years) who underwent LRY or LSG during a hospital admission (January 1, 2012-September 30, 2015)(More)
Purpose. To estimate and compare clinical outcomes and costs associated with mechanical stapling versus hand-sewn sutured technique in creation of ileocolic anastomoses after right sided colon surgery. Methods. A previously conducted meta-analysis was updated for estimates of anastomotic leak rates and other clinical outcomes. A value analysis model was(More)
BACKGROUND AND OBJECTIVES Studies have shown economic and clinical advantages of laparoscopic left-colon resections. Laparoscopic conversion to open is an important surgical outcome. We estimated conversion incidence, identified risk factors, and measured the clinical and economic impact. METHODS In this retrospective study, we used the Premier(More)
