Primary duodenal gastrinomas are now recognized as a common etiology for patients with sporadic Zollinger Ellison Syndrome (ZES); however, the clinical and pathologic features of this condition and long-term outcome after operation are not well characterized. ⋯ Duodenal gastrinomas in patients with sporadic ZES are frequently small, most commonly located in the proximal duodenum, and associated with regional lymph node metastases in 60%. Disease-free survival is lower for patients with regional lymph node metastases suggesting that a more systematic lymphadenectomy to extirpate occult disease may be indicated in this group.

Randomized Controlled Trial Clinical Trial
Improved net protein balance, lean mass, and gene expression changes with oxandrolone treatment in the severely burned.
To determine the effects of the anabolic agent oxandrolone on muscle protein and gene expression in severely burned children. ⋯ Oxandrolone improves protein net balance and lean mass in the severely burned. These changes are associated with increased gene expression for functional muscle proteins.

Complex blunt aortic injury or repair: beneficial effects of cardiopulmonary bypass use.
To compare the outcomes and associated morbidity in patients with blunt aortic injury (BAI) repaired using cardiopulmonary bypass versus no bypass. Special consideration is given to the influence of bypass in the outcome of complex injuries or repair circumstances. ⋯ With the use of cardiopulmonary bypass in the repair of BAI, the incidence of paraplegia/paresis has fallen. While patients with typical injuries and uncomplicated repair can expect good results with either technique, cardiopulmonary bypass provides significant advantages in the repair of those with CI/R. With the use of bypass, no CI/R patient developed paraplegia, while all CI/R patients experienced paraplegia before bypass use. Although others have reported the importance of clamp time, in this series clamp time appeared largely to be a surrogate variable for complexity of injury.

Comparative Study
Evolution of staged versus primary closure of gastroschisis.
Since the introduction of a preformed silo to the authors' practice in 1997, there has been a decrease in primary closure of gastroschisis. To clarify the impact of this change, the authors reviewed their results over the past 10 years. ⋯ A lower incidence of infection and complications related to abdominal compartment syndrome has made staged closure of gastroschisis more common in the authors' practice. While it has resulted in a longer hospital stay, staged closure decreases the risk of long-term bowel dysfunction and need for reoperation.

To examine the breadth of application and resulting outcomes in a university-based extracorporeal membrane oxygenation (ECMO) program directed by pediatric surgeons. ⋯ ECMO can potentially eliminate mortality for meconium aspiration syndrome. Survival for other causes of respiratory failure in neonates and older children, while not as dramatic, still surpasses that anticipated with conventional therapy. Moreover, survival of transplant patients has been comparable to that achieved in other children.
