Review Meta Analysis
An institutional analysis and systematic review with meta-analysis of pneumatic versus hydrostatic reduction for pediatric intussusception.
Intussusception remains a frequent cause of bowel obstruction in children and typically is treated by reduction via enema. Controversy persists regarding the optimal reduction technique to maximize success while minimizing morbidity. ⋯ Pneumatic reduction is more likely to successfully reduce intussusception in children without evidence of increased morbidity. In the context of available expertise, pneumatic reduction should be the method of choice for the treatment of intussusception barring an indication for immediate operative intervention.

Laparoscopic repair of paraesophageal hernia (PEH) has been shown to result in excellent relief of symptoms and improved quality of life (QOL) despite a high radiographically identified recurrence rate. Because there is no uniform definition of PEH recurrence, it is difficult to compare studies reporting on this. This study attempts to introduce consistency to the definition of PEH recurrence based on correlation of symptoms and radiographic findings. ⋯ Our analysis of symptom scores after laparoscopic PEH repair suggests that significant worsening occurs with RRH > 2 cm. Given that there is no consistent description of recurrent PEH, we suggest this as a possible standardized definition. Overall, patients with recurrent PEHs continue to experience excellent QOL and rarely require reoperation.

Traumatic brain injury and shock are among the leading causes of trauma-related mortality. We have previously shown that fresh-frozen plasma (FFP) resuscitation reduces the size of brain lesion and associated swelling compared with crystalloids. We hypothesized that this effect would be associated with an attenuation of circulating nucleosome levels, a biomarker of injury with cytotoxic potential, through reconstitution of circulating deoxyribonuclease-1 (DNAse1), an enzyme identified as critical in nucleosome clearance from the circulation. ⋯ Our results show that resuscitation with FFP attenuates circulating nucleosome levels and prevents DNAse1 depletion. These factors may play a role in the neuroprotective effects observed during early resuscitation with FFP.

Large databases provide a wealth of information for researchers, but identifying patient cohorts often relies on the use of current procedural terminology (CPT) codes. In particular, studies of stoma surgery have been limited by the accuracy of CPT codes in identifying and differentiating ileostomy procedures from colostomy procedures. It is important to make this distinction because the prevalence of complications associated with stoma formation and reversal differ dramatically between types of stoma. Natural language processing (NLP) is a process that allows text-based searching. The Automated Retrieval Console is an NLP-based software that allows investigators to design and perform NLP-assisted document classification. In this study, we evaluated the role of CPT codes and NLP in differentiating ileostomy from colostomy procedures. ⋯ CPT codes can identify effectively patients who have had stoma procedures and are adequate in distinguishing between formation and reversal; however, CPT codes cannot differentiate ileostomy from colostomy. NLP can be used to differentiate between ileostomy- and colostomy-related procedures. The role of NLP in conjunction with electronic medical records in data retrieval warrants further investigation.

Comparative Study
Provider versus patient factors impacting hospital length of stay after pancreaticoduodenectomy.
Studies reporting perioperative outcomes after pancreaticoduodenectomy (PD) have focused on morbidity and mortality. Understanding factors that impact hospital duration of stay may have cost-saving implications. We sought to examine variation in duration of stay after PD occurring at the patient, surgeon, and hospital levels. ⋯ PD patients treated by higher volume surgeons and at higher volume hospitals had a shorter duration of stay. Although some patient-level factors impact duration of stay after PD, nonclinical factors such as surgeon and hospital volume were also important contributors to duration of stay.
