MATERIALS AND METHODS After institutional review board approval, the charts(More)
PURPOSE Small intercostal spaces and limited pleural space significantly limits the use of 12-mm stapling devices in pediatric thoracoscopic surgery. The goal of this study was to compare sealing of lung tissue by the 5-mm Ligasure (Valley Lab, Boulder, CO) device to a standard 12-mm Endo-GIA stapler (US Surgical, Norwalk, CT). METHODS Institutional(More)
OBJECTIVE The purpose of this study was to demonstrate the safety and efficacy of laparoscopy in children with perforated appendicitis. METHODS This is a retrospective review of consecutive patients under the age of 18, operated on for perforated appendicitis between September 1997 and December 1999. RESULTS Sixty-nine patients were operated on for(More)
BACKGROUND The authors propose that U-Clips can significantly decrease the technical difficulty of performing thoracoscopic esophageal reconstruction, thus, reducing operating time, the incidence of postoperative leak, and stricture rate. METHODS After obtaining Institutional Animal Care and Use Committee approval, 3 4-kg female piglets underwent complete(More)
STUDY OBJECTIVE To assess whether near-infrared spectroscopy can detect testicular hypoxia in a sheep model of testicular torsion within 6 hours of experimental torsion. METHODS This was a randomized, controlled, nonblinded study. Trans-scrotal, near-infrared, spectroscopy-derived testicular tissue saturation of oxygen values were obtained from the(More)
BACKGROUND Traumatic pancreatic injury is associated with significant morbidity and mortality. We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively. STUDY DESIGN The National Trauma Data Bank was evaluated from 2002 to 2011. Patients less than18 years of age with blunt pancreatic(More)

We report the case of a 17-year-old female with symptoms of intermittent small bowel obstruction. Computed tomography scan of the abdomen revealed an intussusception. The patient underwent a laparoscopic-assisted resection of the mass, which proved to be gastric heterotopia of the jejunum. We report on the case, discuss the surgical approach, and review the(More)
PURPOSE The aim of this study was to investigate factors that impact tactile sensation during minimally invasive pediatric surgery. METHODS Three different 3-mm Maryland laparoscopic instruments were tested with and without the resistance of a trocar (Ethicon 3-mm): Jarit (24-cm shaft, 113 g), Storz (30-cm shaft, 62 g), and an ultra-light prototype (24-cm(More)
