Enhanced recovery after surgery (ERAS) is a systematic approach to optimize a patient’s health and improve clinical outcomes, increase patient satisfaction and decrease healthcare costs. Enhanced recovery protocols have been used across a variety of surgical disciplines and patient groups to improve patient safety and reduce hospital length of stay without increasing return visits to the system. ERAS involves the application of clinical decision making throughout the patient experience with interventions in the preoperative, perioperative and post operative phases. In addition, ERAS is multidisciplinary and the success of an ERAS program is dependent on the effort and integration of stakeholders across the healthcare system. Utilization of ERAS systems have grown across the global adult surgical community over the last three decades and adoption in pediatric surgery has only occurred recently. Hospitals in both adult and pediatric surgery have found that implementation of ERAS systems lead to a shortened length of stay and reduced complications without increasing patient returns to the system. Importantly patients who have surgery within an ERAS program experience less pain, less opioid utilization, a quicker recovery and increased satisfaction. In pediatric surgery ERAS has successfully been employed across most all disciplines from congenital cardiac surgery to colorectal surgery. The evolution of ERAS continues as a paradigm of quality and safety.

Background:Pulmonary hypoplasia and hypertension is a leading cause of morbidity and mortality in congenital diaphragmatic hernia (CDH). The etiologic insult occurs early in gestation highlighting the potential of prenatal interventions. We evaluated prenatal pharmacologic therapies in the nitrofen CDH model.Methods:Olive oil or nitrofen were administered alone or with dexamethasone (DM), sildenafil, or DM+sildenafil to pregnant rats. Newborn pups were assessed for lung function, structure and pulmonary artery (PA) flow and resistance.Results:Prenatal DM treatment of CDH pups increased alveolar volume density (Vva), decreased interalveloar septal thickness, increased tidal volumes and improved ventilation without improving oxygenation or PA resistance. Sildenafil decreased PA resistance and improved oxygenation without improving ventilation or resulting in significant histologic changes. DM+sildenafil decreased PA resistance, improved oxygenation and ventilation while increasing Vva and decreasing interalveolar septal and pulmonary arteriole medial wall thickness. Lung and body weights were decreased in pups treated with DM and/or sildenafil.Conclusion:Prenatal DM or sildenafil treatment increased pulmonary compliance and decreased pulmonary vascular resistance respectively, and was associated with improved neonatal gas exchange but had a detrimental effect on lung and fetal growth. This study highlights the potential of individual and combined prenatal pharmacologic therapies for CDH management.

Appendicitis is a common condition in childhood and adolescence that frequently requires urgent surgical intervention. For almost two centuries appendicitis has been recognized as a medical problem with a surgical solution. Currently the appendix can be removed with a minimally invasive approach, low anesthetic and surgical risk, and swift hospital discharge. Despite these advances, surgery and anesthesia have associated risks including postoperative infection, bleeding, hernia and organ injury among others. In addition, surgery requires time off of school and work to recover and associated healthcare costs can be significant. In both adult and pediatric populations, quality data suggesting a nonoperative approach is suggesting a change to the traditional surgical paradigm. Adults studies have demonstrated both safety and efficacy in the nonoperative management of acute appendicitis. In selected children with uncomplicated appendicitis, initial nonoperative management has been shown to be safe with fewer complications, fewer disability days and less healthcare costs while avoiding the risks inherent to surgery. Ongoing randomized controlled clinical trials in both the United States and Europe seek to further demonstrate the safety of nonoperative management and assist physicians with educating patients about the risk profile of their treatment decision. In complicated appendicitis presenting with abscess or acute appendiceal phlegmon, an initial nonoperative strategy with or without abscess drainage followed by interval appendectomy is the current state of the art though the utility of interval appendectomy is questioned.

In utero hematopoietic cell transplantation (IUHCT) offers the potential to achieve allogeneic engraftment and associated donor-specific tolerance without the need for toxic conditioning, as we have previously demonstrated in the murine and canine models. This strategy holds great promise in the treatment of many hematopoietic disorders, including the hemoglobinopathies. Graft-versus-host disease (GVHD) represents the greatest theoretical risk of IUHCT and has never been characterized in the context of IUHCT. We recently described a preclinical canine model of IUHCT, allowing further study of the technique and its complications. We aimed to establish a threshold T cell dose for IUHCT-induced GVHD in the haploidentical canine model and to define the GVHD phenotype. Using a range of T cell concentrations within the donor inoculum, we were able to characterize the phenotype of IUHCT-induced GVHD and establish a clear threshold for its induction between 3% and 5% graft CD3+cell content. Given the complete absence of GVHD at CD3 doses of 1% to 3% and the excellent engraftment with the lowest dose, there is a safe therapeutic index for a clinical trial of IUHCT.

After acute necrotizing pancreatitis (ANP), a pancreatic fistula may occur from disconnected pancreatic duct syndrome (DPDS) where a segment of the pancreas is no longer in continuity with the main pancreatic duct. To study the outcome of patients treated using Roux-Y pancreatic fistula tract-jejunostomy for DPDS after ANP. Between 2002 and 2011, patients treated for DPDS in the setting of endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopanreatography (MRCP) documented main pancreatic duct disruption with Roux-Y pancreatic fistula tract-jejunostomy. In all, seven patients with DPDS were treated. The median age was 62 years (range 49-78) and five were men. The cause of ANP was gallstones (2), alcohol (1), ERCP (1) and idiopathic (3). Pancreatic necrosectomy was done in six patients. Time from onset of pancreatitis to fistula drainage was 270 days (164-365). Pancreatic fistulae arose from DPDS in the head/neck (4) and body/tail (3). Patients had a median fistula output of 140 ml (100-200) per day before surgery. The median operative time was 142 min (75-367) and estimated blood loss was 150 ml (25 to 500). Patients began an oral diet on post-operative day 4 (3-6) and were hospitalized for a median of 7 days (5-12). The median follow-up was 264 days (29-740). Subsequently, one patient required a distal pancreatectomy. After surgery, three patients required oral hypoglycaemics. No patient developed pancreatic exocrine insufficiency. Internal surgical drainage using Roux-en-Y pancreatic fistula tract-jejunostomy is a safe and definitive treatment for patients with DPDS. ? 2011 International Hepato-Pancreato-Biliary Association.
