Obesity is an increasingly common serious chronic health condition. We sought to determine the impact of body mass index (BMI) on perioperative outcomes in patients undergoing major intra-abdominal cancer surgery. A prospective, multi-institutional, risk-adjusted cohort study of patients undergoing major intra-abdominal cancer surgery was performed from the(More)
OBJECTIVE We sought to examine the effect of body mass index (BMI) on 30-day morbidity and mortality in a large cohort of patients undergoing nonbariatric general surgery. SUMMARY BACKGROUND DATA Obesity has long been considered a risk factor for poor outcomes from a variety of surgical procedures, yet recent studies of critically and chronically ill(More)
The open components separation technique (CST) for hernia repair allows for autologous tissue repair with approximation of the midline fascia in patients with complex hernias. CST requires creation of large undermining skin flaps, whereas the endoscopic component separation technique (ECST) is performed without division of the epigastric perforating(More)
OBJECTIVE To examine outcomes in patients who receive small amounts of intraoperative blood transfusion. DESIGN Longitudinal, uncontrolled observational study evaluating results of intraoperative transfusion in patients entered into the American College of Surgeons National Surgical Quality Improvement Program database. We made propensity-matched(More)
PURPOSE Alpha blockade has been well described clinically for expulsion of distal ureteral stone. However, the in-vivo effects of α-blockade on ureteral dynamics during stone passage are not clear. We studied the effects of oral alfuzosin on ureteral pressure and peristalsis in a distally obstructed porcine ureter. METHODS Twenty-four female domestic(More)
BACKGROUND Transfusion of packed red blood cells (PRBCs) increases morbidity and mortality in select surgical specialty patients. The impact of low-volume, leukoreduced RBC transfusion on general surgery patients is less well understood. STUDY DESIGN The American College of Surgeons National Surgical Quality Improvement Program participant use file was(More)
BACKGROUND Studies of specific procedures have shown increases in infectious complications with operative duration. We hypothesized that operative duration is independently associated with increased risk-adjusted infectious complication (IC) rates in a broad range of general surgical procedures. STUDY DESIGN We queried the American College of Surgeons(More)
OBJECTIVE The purpose of this study was to determine the relationship between the American Society of Anesthesiologists' Physical Status (ASA PS) classifications and the other National Surgical Quality Improvement Program (NSQIP) preoperative risk factors. BACKGROUND The ASA PS has been shown to predict morbidity and mortality in surgical patients but is(More)
BACKGROUND AND OBJECTIVES Use of bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) is controversial for diagnosing bone loss in CKD patients on dialysis. The alternative quantitative computed tomography (QCT) is expensive and requires high radiation exposure. This study compared the two techniques and evaluated serum biochemical(More)
BACKGROUND As laparoscopic surgery is applied to colorectal surgery procedures, it becomes imperative to delineate whether there is an operative duration where benefits diminish. OBJECTIVE The purpose of this work was to determine whether benefits of a laparoscopic right colectomy compared with an open right colectomy are diminished by prolonged operative(More)
