With the advances in medicine, the incidence of Fontan physiology-related complications is likely to increase, and the incidence of HCC will also increase accordingly. As early diagnosis of HCC results in better patient outcomes, a surveillance guideline for HCC after the FP should be developed.

BACKGROUND: This study aimed to determine perinatal risk factors for 30-day mortality of congenital diaphragmatic hernia (CDH) patients and develop a prognostic index to predict 30-day mortality of CDH patients. Identifying risk factors that can prognosticate outcome is critical to obtain the best management practices for patients. METHODS: A retrospective study was performed for patients who were diagnosed with CDH from November 2000 to August 2016. A total of 10 prenatal risk factors and 14 po

A considerable number of patients with ARM had AAs. Our data are useful for predicting AAs in patients with ARM.

Silicon atomic-layer etching (ALET) was carried out by the adsorption of to form silicon chlorides followed by the desorption of the silicon chlorides formed on the surface by irradiating an Ar neutral beam of a low energy. The silicon surface during the silicon ALET was investigated by X-ray photoelectron spectroscopy (XPS) and atomic force microscopy, and its etch mechanism was studied. XPS data showed that during the adsorption stage, silicon chloride bonding peaks related to SiCl and were fo

Meckel's diverticulum is a rare condition in neonates with reports of concurrent Meckel's diverticulum and omphalocele being few. Herein, we present a case of omphalocele associated with perforated Meckel's diverticulum.

The use of minimally invasive surgery (MIS) in pediatric patients has been steadily increasing in recent years. However, its use for diagnosing and treating abdominal tumors in children is still limited compared with adults, especially when malignancy is a matter of debate. Here, we describe the experience at our center with pediatric abdominal tumors to show the safety and feasibility of MIS.Based on a retrospective review of patient records, we selected for study those pediatric patients who h

BACKGROUND: Neurologically impaired children (NIC) often experience swallowing difficulties and gastroesophageal reflux disease (GERD). Although these conditions could place children in a state of poor nutritional status and prevent them from thriving, there is insufficient research evaluating growth and nutritional status following fundoplication in these patients. METHOD: This is a retrospective study of patients who were neurologically impaired and underwent Nissen fundoplication between Apri

Anorectal innervation that governs sensation, motor function, and rectal accommodation can be influenced by the type of surgical procedure used to treat children with Hirschsprung disease. At our institution, we began to perform single-stage, laparoscopy-assisted transanal endorectal pull-through (LATEP) with submucosal dissection and anastomosis of the ganglionated bowel at 2 different levels relative to the dentate line.This retrospective study describes postoperative stool frequency changes i

The proportion of the pediatric surgery performed by PS rather than GS is increasing in Korea, but it is still widely performed by GS. PSs have better operative outcomes for acute abdominal surgery in the NICU than GSs. We believe that at least the index operation or the NICU operation should be performed by PS for better outcome, and that a minimum of 63 PSs are needed in Korea to do so. In addition, approximately 200 PSs will be required in Korea in order to manage main pediatric diseases and

BACKGROUND: Frequent stooling immediately after pull-through (PT), fecal soiling, and constipation are chronic complications of Hirschsprung's disease (HD). This study aimed to investigate the longitudinal outcomes in terms of bowel function of patients below the age of 1 year undergoing PT. METHODS: We retrospectively evaluated 396 patients who underwent PT for HD between September 1979 and March 2014. Stool frequency was analyzed up to 10 years of age, and soiling and constipation were analyze
