Randomized Controlled Trial Multicenter Study
Does type of pancreaticojejunostomy after pancreaticoduodenectomy decrease rate of pancreatic fistula? A randomized, prospective, dual-institution trial.
Pancreatic fistula (PF) is one of the most common complications after pancreaticoduodenectomy. There have been no large prospective randomized trials evaluating PF rates comparing invagination versus duct to mucosa pancreaticojejunostomy. We tested the hypothesis that a duct to mucosa pancreaticojejunostomy would reduce the PF rate. ⋯ This dual-institution prospective randomized trial reveals considerably fewer fistulas with invagination compared with duct to mucosa pancreaticojejunostomy after pancreaticoduodenectomy. Results confirm increased PF rates in soft as compared with hard glands. Additional studies are needed to define the optimal technique of pancreatic reconstruction after pancreaticoduodenectomy.

Multicenter Study
Impact of conversion on surgical outcomes after laparoscopic operation for rectal carcinoma: a retrospective study of 1,073 patients.
In laparoscopic operations for rectal carcinoma, only a few multicenter studies of a large number of patients have examined the impact of conversion on outcomes and determined risk factors for conversion. This study was designed to evaluate short-term outcomes and risk factors for conversion to open operation in laparoscopic operations for rectal carcinoma. ⋯ Conversion to open operation is associated with greater morbidity than completed laparoscopic resection. Body mass index and the particular laparoscopic procedure are risk factors for conversion, indicating that appropriate patient selection is essential in laparoscopic operations for rectal carcinoma.

Randomized Controlled Trial Multicenter Study Comparative Study
Human polymerized hemoglobin for the treatment of hemorrhagic shock when blood is unavailable: the USA multicenter trial.
Human polymerized hemoglobin (PolyHeme, Northfield Laboratories) is a universally compatible oxygen carrier developed to treat life-threatening anemia. This multicenter phase III trial was the first US study to assess survival of patients resuscitated with a hemoglobin-based oxygen carrier starting at the scene of injury. ⋯ Patients resuscitated with PolyHeme, without stored blood for up to 6 U in 12 hours postinjury, had outcomes comparable with those for the standard of care. Although there were more adverse events in the PolyHeme group, the benefit-to-risk ratio of PolyHeme is favorable when blood is needed but not available.

Multicenter Study
Nationwide survey of alcohol screening and brief intervention practices at US Level I trauma centers.
In 2007, the American College of Surgeons (ACS) Committee on Trauma implemented a requirement that Level I trauma centers must have a mechanism to identify patients who are problem drinkers and the capacity to provide an intervention for patients who screen positive. Although the landmark alcohol screening and brief intervention (SBI) mandate is anticipated to impact trauma practice nationwide, a literature review revealed no studies that have systematically documented SBI practice pre-ACS requirement. ⋯ The investigation observed marked variability across Level I centers in the percentage of patients screened and in the nature and extent of intervention delivery in screen-positive patients. In the wake of the ACS Committee on Trauma requirement, future research could systematically implement and evaluate training in the delivery of evidence-based alcohol interventions and training in development of trauma center organizational capacity for sustained delivery of SBI.

Multicenter Study
Patterns and outcomes of pediatric facial fractures in the United States: a survey of the National Trauma Data Bank.
Pediatric trauma involving the bones of the face is associated with severe injury and disability. Although much is known about the epidemiology of facial fractures in adults, little is known about national injury patterns and outcomes in children in the US. ⋯ Causes and patterns of facial fractures vary with age. Cranial and central facial injuries are more common among toddlers and infants, and mandible injuries are more common among adolescents. Although bony craniofacial trauma is relatively uncommon among the pediatric population, it remains a substantial source of mortality, morbidity, and hospital resource use. Continued efforts toward injury prevention are warranted.
