Pyloric duplication is a rare subset of alimentary tract duplications that can present in a manner almost identical to hypertrophic pyloric stenosis. Diagnosis can typically be made with an upper gastrointestinal series and ultrasound, though axial imaging is occasionally required. Because most of these malformations do not communicate with the lumen, they can be effectively managed with partial excision and ablation of the common wall mucosa. Here we present an 11-day-old female with pyloric duplication that was successfully managed laparoscopically.

Choledocholithiasis is a rare diagnosis in the infant population with poorly defined optimal management. Endoscopic and operative interventions are both technically challenging. Endoscopic retrograde cholangiopancreatography (ERCP), common bile duct exploration and laparoscopic cholecystectomy are typically safe and successful when performed. However, choledocholithiasis has been reported to spontaneously resolve in up to 60% of cases in neonates and infants. We present five cases of choledocholithiasis in infants and a comprehensive review of the literature. Based on our review and experience, we make a recommendation that clinicians should proceed with a selective approach in the management of this disease based on severity of symptoms, co-morbidities, and the available surgical and endoscopic capabilities of each institution.

Objective: Trauma-related Acute Respiratory Distress Syndrome (TR-ARDS) mortality ranges from 30 to 80%. Extracorporeal membrane oxygenation (ECMO) has demonstrated a survival benefit in select cases of TR-ARDS. In order to provide improved patient selection, we evaluated predictors of mortality in TR-ARDS patients receiving ECMO, hypothesizing age and severe thoracic trauma as risk factors for mortality. Methods: The Trauma Quality Improvement Program (2010–2016) was queried for patients ≥ 18-years-old with TR-ARDS receiving ECMO. Survivors were compared to those who died. A multivariable logistic regression model was used for analysis and included covariates known to increase risk of mortality in trauma patients. Results: From 362 TR-ARDS patients on ECMO, 226 (62.4%) survived and 136 (37.6%) died. Those who died were older (median, 28 vs. 24-years-old, p = 0.036) and had a higher injury severity score (29 vs. 26, p = 0.040) than survivors. After adjusting for covariates, independent predictors of mortality included a severe head (OR=2.66, CI=1.29–5.49, p = 0.008) and thorax (OR =3.52, CI=1.96–6.33, p
