BACKGROUND Obesity is associated with chronic inflammation, which includes increased macrophage accumulation in adipose tissue (AT) and upregulation of chemokines and cytokines. T cells also play important roles in chronic inflammatory diseases such as atherosclerosis but have not been well studied in obesity. METHODS AND RESULTS Flow cytometric analysis(More)
BACKGROUND The NSQIP database enables measurement of postoperative outcomes across a spectrum of practice settings. This allows for observations about potential effects of resident participation in surgical care during training. STUDY DESIGN We queried the NSQIP database for 6 index laparoscopic surgical procedures performed during 2005-2008. Selected(More)
Multiple techniques have been used for the repair of complex abdominal wall defects after recurrent incisional hernias with varying rates of success. Primary repair has been associated with high recurrence rates, and prosthetic mesh placement is contraindicated in contaminated surgical fields. The development of biologic prostheses has changed the approach(More)
BACKGROUND Current literature lacks sufficient data on outcomes after extensive laparoscopic liver resections. We hypothesized that laparoscopic right hepatectomy (LRH) is associated with better clinical outcomes and less overall hospital costs than open right hepatectomy (ORH), supporting the notion that major laparoscopic hepatic resections carry(More)
Glycemic disorders resolve following Roux-en-Y gastric bypass (RYGB) surgery, but early and longer-term mechanisms regarding effects on β-cell dysfunction as well as relationships with decreasing adiposity are not well understood. We evaluated longitudinal changes in peripheral insulin sensitivity (Si), the acute insulin response to glucose (AIRg), and the(More)
BACKGROUND Splenectomy has 50% to 70% long-term efficacy for immune thrombocytopenic purpura (ITP). In some patients, relapse is due to the presence of residual accessory splenic tissue. METHODS A 44-year-old male had ITP since 1983 with splenectomy in 1985. He had a transient response, but then developed severe thrombocytopenia refractory to multiple(More)
BACKGROUND Hypergastrinemia in patients with pernicious anemia is a major regulator contributing to enterochromaffin-cell hyperplasia and, ultimately, to gastric carcinoids. STUDY DESIGN Between 1990 and 2003, we studied 8 women and 10 men with pernicious anemia and gastric carcinoids; their mean age was 50 years. Serum gastrin levels ranged from 740 to(More)
OBJECTIVE To analyze postoperative outcomes, morbidity, and mortality following enterocutaneous fistula (ECF) takedown. DESIGN, SETTING, AND PATIENTS Retrospective review of the complete medical records of patients who presented to a single tertiary care referral center from December 24, 1987, to June 18, 2010, and subsequently underwent definitive(More)
