In patients undergoing elective partial pancreatectomy, our aim was to evaluate the effect of metabolic syndrome (MS) on postoperative mortality, morbidity, and utilization of hospital resources. Our hypothesis was that MS is associated with worse surgical outcomes after pancreatectomy. Fifteen thousand eight hundred thirty-one patients undergoing elective(More)
BACKGROUND Decompression of tension physiology may be lifesaving, but significant doubts remain regarding ideal needle thoracostomy (NT) catheter length in the treatment of tension physiology. We aimed to demonstrate increased clinical effectiveness of longer NT angiocatheter (8 cm) compared with current Advanced Trauma Life Support recommendations of 5-cm(More)
BACKGROUND There is a paucity of literature regarding rates, trends, and outcomes of women with endometriosis undergoing elective colorectal resections in the United States. It was been suggested that endometriosis requiring colorectal resection is well suited for minimally invasive surgery. MATERIALS AND METHODS The American College of Surgeons National(More)
BACKGROUND In patients undergoing elective hepatectomy, we aimed to evaluate the effect of preoperative anemia on postoperative mortality, morbidity, readmission, risk of blood transfusion, and duration of hospital stay. METHODS A total of 4,170 patients who underwent elective hepatectomy from 2010 to 2012 were identified in the American College of(More)
OBJECTIVE With improving medical therapies for chronic conditions, elderly patients increasingly present as candidates for operative intervention for degenerative diseases of the spine. To date, there is a paucity of studies examining complications in lumbar decompression, without fusion, that include patients older than 80 years. Using a multicenter(More)
OBJECTIVE To determine the rate of surgical site infection (SSI) after resection of an intracranial neoplasm using the American College of Surgeons National Surgical Quality Improvement Program data set and to identify potential risk factors associated with SSI. METHODS The National Surgical Quality Improvement Program Participant Use Data File was(More)
BACKGROUND One of the main complications of inguinal hernia repair continues to be recurrence. Commonly cited prior reports from relatively small studies estimate this rate to be 1% to 5% in the United States. Although some reports have found higher recurrence rates, they get little attention on the national stage or in other large studies. We sought to(More)
OBJECTIVE A single level discectomy is one of the most common procedures performed by spine surgeons. While some practitioners utilize the microscope, others do not. We postulate improved visualization with an intraoperative microscope decreases complications and inferior outcomes. METHODS A multicenter surgical registry was utilized for this(More)
BACKGROUND Patients with IBD have a higher baseline risk of venous thromboembolism, which further increases with surgery. Therefore, extended venous thromboembolism chemoprophylaxis has been suggested in certain high-risk cohorts. OBJECTIVE The purpose of this study was to determine whether the underlying diagnosis, operative procedure, or both influence(More)
OBJECTIVE This study moves beyond previous cohort studies and benchmark data by studying a population of elective spine surgery from a multicenter registry in an effort to validate, disprove, and/or identify novel risk factors for dural tears. METHODS A retrospective cohort analysis queried a multicenter registry for patients with degenerative spinal(More)
