The purpose this study was review clinical presentations outcomes IAAA establish a treatment strategy for optimal IAAA.Electronic medical records 13 patients treated at Seoul National University Hospital between March 2004 December 2012 were retrospectively reviewed.Mean age 64.2 (median 70, range 20-79) years. Aneurysms located in infrarenal (n=7), arteries (n=5), suprarenal (n=1)....

Abstract Very low birth weight (VLBW) neonates experience various problems, including meconium-related ileus (MRI). This study investigated the risk factors of MRI and surgical in VLBW infants. admitted to Neonatal Intensive Care Unit Seoul National University Children’s Hospital from October 2002 September 2016 were included study. The diagnostic criteria for a decreased frequency defecation with intolerable feeding, vomiting, increased gastric residue (>50%); meconium-filled bowel...

We developed a 3D-printed thoracoscopic surgery simulator for esophageal atresia with tracheoesophageal fistula (EA-TEF) and assessed its effectiveness in educating young pediatric surgeons. Prototype production modifications were repeated five times before producing the 3-D printed final product based on patient's preoperative chest computed tomography. A 24-item survey was used to rate simulator, adapted from previous report, 16 surgeons an average of 6.2 years experience validation....

Introduction The treatment of Hirschsprung disease (HD) is pull-through (PT) surgery. Redo PT can be performed in 1 to 10% patients after initial PT. In this study, we reviewed the causes and associated factors redo Materials Methods We retrospectively medical charts 657 with HD who underwent surgeries between September 1979 January 2016. indications for are as follows. First, there were persistent obstructive symptoms first operation, (1) transition zone shown definitely on contrast (2)...

Rationale: Kaposiform hemangioendothelioma (KHE) is an aggressive vascular tumor, mainly occurring in infants and young children previously reported cases were cutaneous or visceral form. Intestinal kaposiform hemangioma was first 2012. type KHE showed better prognosis if the lesion limited gastrointestinal tract coagulopathy not accompanied. Since number of small, further study for treatment options need to be done. Patient concerns: We described case a 1-month-old female who had abdominal...
