Adipose tissue (AT) can accumulate macrophages and secrete several inflammatory mediators. Despite its pivotal role in the progression of chronic inflammatory processes such as atherosclerosis, the adaptive role of immunity in obesity remains poorly explored. Visceral AT of diet-induced obese C57BL/6 mice had higher numbers of both CD4(+) and CD8(+) T cells(More)

IMPORTANCE Emerging data support bariatric surgery as a therapeutic strategy for management of type 2 diabetes mellitus. OBJECTIVE To test the feasibility of methods to conduct a larger multisite trial to determine the long-term effect of Roux-en-Y gastric bypass (RYGB) surgery compared with an intensive diabetes medical and weight management (Weight(More)
The role of laparoscopic appendectomy for perforated appendicitis remains controversial. This study aimed to compare laparoscopic and open appendectomy outcomes for children with perforated appendicitis. Over a 36-month period, 111 children with perforated appendicitis were analyzed in a retrospective review. These children were treated with either(More)
OBJECTIVES:Little consensus exists regarding the endoscopic assessment of the esophagogastric junction after antireflux surgery. The purpose of this report is to characterize the gastroesophageal valve appearance unique to each type of antireflux procedure and to introduce an endoscopic lexicon by which to describe this anatomic region.METHODS:Endoscopic(More)
BACKGROUND Minimally invasive Collis gastroplasty is an established technique for managing the shortened esophagus. The purpose of this report is to describe our new technique, the wedge gastroplasty, and report the short-term outcomes. METHODS All patients (n = 143) undergoing laparoscopic fundoplication from May 2000 to March 2001 were assessed(More)
BACKGROUND Retrograde intussusception (RI) at the jejunojejunostomy can occur after Roux-en-Y gastric bypass (RYGB). Although this complication is rare, it has been encountered more frequently as the number of bariatric procedures have increased. Little data is available to assist surgeons with the optimal management of this condition. Our objectives were(More)
PURPOSE The purpose of this study was to compare the incidence and type of technical complications seen in a concurrent series of pyloromyotomies done open and laparoscopically. METHODS The medical records of all patients who underwent pyloromyotomy for congenital hypertrophic pyloric stenosis over a 66-month period were reviewed (n = 457). Information(More)
Background: The benefit of laparoscopy in the treatment of pediatric acute appendicitis continues to be controversial, particularly as it relates to operative time and costs. Methods: We reviewed the charts of 200 children who underwent appendectomy for acute appendicitis concurrently over 35 months at a large teaching children’s hospital. Results:(More)
The appropriate management of biliary tract disease during pregnancy is uncertain. Although laparoscopic cholecystectomy can be performed safely during pregnancy, the timing and indications for this surgical intervention have not been firmly established. We constructed a Markov decision analytic model that incorporates maternal well-being and fetal outcome(More)
