According to currently accepted diagnostic criteria, ultrasonography confirms hypertrophic pyloric stenosis (HPS) when the pyloric muscle thickness (MT) is greater than 4 mm and the pyloric channel length (CL) is greater than 15 mm. Hypertrophic pyloric stenosis frequently presents in newborns younger than 21 days; yet, the diagnostic criteria in this younger population remain poorly defined. We, therefore, sought to define the diagnostic criteria for HPS in newborns younger than 21 days. ⋯ These findings suggest that current guidelines to diagnose HPS do not accurately diagnose HPS in children younger than 3 weeks, and these findings raise the need to evaluate the decision analysis algorithm using prospective studies.

Given the perceived technical demands of laparoscopic appendectomy and the expected postoperative morbidity in patients with a well-defined abscess, initial percutaneous drainage has become an attractive option in this patient population. This strategy allows for a laparoscopic appendectomy to be performed in an elective manner at the convenience of the surgeon. However, the medical burden on the patient and on the quality of patient outcomes has not been described in the literature. Therefore, we audited our experience with initial percutaneous drainage followed by laparoscopic interval appendectomy to evaluate the need for a prospective trial. ⋯ The use of initial percutaneous aspiration/drainage of periappendiceal abscess followed by interval appendectomy is an effective approach. However, this management poses complication risks and uses considerable resources. Therefore, this strategy should be compared with early operation in a prospective trial.

The purpose of this study was to identify preoperative predictors of adverse outcomes in infants undergoing surgical ligation of patent ductus arteriosus (PDA). ⋯ The PDA ligation can be accomplished safely; however, some neonates have prolonged recovery. Lower gestational age and low peak velocity (<2.6 m/s) at the PDA shunt correlate with lengthened ventilator requirement after surgery.

Blunt trauma is the leading cause of pediatric injury, but pediatric aortic injuries are rare. We undertook this study to investigate the demographics, treatment, and outcomes of children with blunt aortic injuries and report our experience over a 10-year period. ⋯ Blunt aortic injury in children is uncommon and is primarily associated with motor vehicle crashes. Injuries to the abdominal aorta were seen with restrained children vs those to the thoracic aorta that were seen in children who were unrestrained.

Case Reports
Combined endovascular and surgical recanalization after central venous catheter-related obstructions.
Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. ⋯ The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.
