Identification of Genes Associated With Hirschsprung Disease, Based on Whole-Genome Sequence Analysis, and Potential Effects on Enteric Nervous System Development.

Background & Aims: Hirschsprung disease, or congenital aganglionosis, is believed to be oligogenic-that is, caused by multiple genetic factors. We performed whole-genome sequence analyses of patients with Hirschsprung disease to identify genetic factors that contribute to disease development and analyzed the functional effects of these variants.

Methods: We performed whole-genome sequence analyses of 443 patients with short-segment disease, recruited from hospitals in China and Vietnam, and 493 ethnically matched individuals without Hirschsprung disease (controls).

Combination of plasma white blood cell count, platelet count and C-reactive protein level for identifying surgical necrotizing enterocolitis in preterm infants without pneumoperitoneum.

Purpose: To evaluate whether plasma white blood cell count (WBC), platelet count (PLT), and C-reactive protein level (CRP) can be used to differentiate surgical necrotizing enterocolitis (NEC) from medical NEC.

Methods: Preterm infants admitted between January 1, 2011 and July 31, 2015 were stratified by the need of surgery as surgical NEC (n = 41) and medical NEC (n = 43). The values of WBC, PLT and CRP were collected at time before NEC occurred (T), at onset of NEC (T) and when surgical assessment was required (T).

Common genetic variants of GPC1 gene reduce risk of biliary atresia in a Chinese population.

Background: Biliary atresia (BA) is a major neonatal cholestatic disease and main indication for pediatric liver transplantation in the world. Recently, GPC1 has been implicated as a risk gene for BA by genetic studies and follow-up functional experiments on zebrafish.

Methods: Two common genetic variants of GPC1, rs2292832 and rs3828336, were selected systematically through 'SNPinfo', and were examined using TaqMan Genotyping Assays for association studies in a Chinese population containing 134 cases and 618 controls.

Common genetic variants regulating ADD3 gene expression alter biliary atresia risk.

Background & Aims: Biliary atresia (BA) is a rare and most severe cholestatic disease in neonates, but the pathogenic mechanisms are unknown. Through a previous genome wide association study (GWAS) on Han Chinese, we discovered association of the 10q24.2 region encompassing ADD3 and XPNPEP1 genes, which was replicated in Chinese and Thai populations.

RET mutational spectrum in Hirschsprung disease: evaluation of 601 Chinese patients.

Rare (RVs) and common variants of the RET gene contribute to Hirschsprung disease (HSCR; congenital aganglionosis). While RET common variants are strongly associated with the commonest manifestation of the disease (males; short-segment aganglionosis; sporadic), rare coding sequence (CDS) variants are more frequently found in the lesser common and more severe forms of the disease (females; long/total colonic aganglionosis; familial).Here we present the screening for RVs in the RET CDS and intron/exon boundaries of 601 Chinese HSCR patients, the largest number of patients ever reported.

The effect of laparoscopic excision vs open excision in children with choledochal cyst: a midterm follow-up study.

Purpose: Cyst excision with hepaticojejunostomy has been the classic procedure for treating choledochal cysts. Recently, laparoscopic treatment of the disease has gained popularity worldwide. The aim of this study is to evaluate whether laparoscopic management of choledochal cysts is as feasible and safe as conventional open surgery in children with this disease.

Laparoscopic cholecystocholangiography for diagnosis of prolonged jaundice in infants, experience of 144 cases.

Methods: 144 consecutive patients with suspected biliary atresia were included in this retrospective study.

Further evidence of the anti-inflammatory effects of silver nanoparticles.

The production of pure silver in nanoparticle size has opened new dimensions in the clinical use of this precious metal. We and others have demonstrated previously that silver nanoparticles (nAg) possess efficient antimicrobial activity. Herein we show they may also have significant anti-inflammatory effects in a postoperative peritoneal adhesion model.

Laparoscopic excision of choledochal cyst and Roux-en-Y hepaticojejunostomy in symptomatic neonates.

Purpose: Choledochal cysts require surgical excision, preferably before the onset of cholangitis. Recently, it has become feasible to accomplish the excision laparoscopically in adults and older children. Yet, whether laparoscopic excision of choledochal cyst can be performed safely in symptomatic neonates with choledochal cyst is unclear.

Genome-wide association study identifies NRG1 as a susceptibility locus for Hirschsprung's disease.

Hirschsprung's disease (HSCR), or aganglionic megacolon, is a congenital disorder characterized by the absence of enteric ganglia in variable portions of the distal intestine. RET is a well-established susceptibility locus, although existing evidence strongly suggests additional loci contributing to sporadic HSCR. To identify these additional genetic loci, we carried out a genome-wide association study using the Affymetrix 500K marker set.

Total extrapleura sternal elevation for the correction of pectus excavatum in children.

Purpose: The aim of this study was to evaluate the efficacy and safety of the thoracoscopic total extrapleural approach of the Nuss procedure for the correction of pectus excavatum in children.

Materials And Methods: Under thoracoscopic guidance, an extrapleural tunnel was created by using a blunt dissector via a right thoracic incision. A steel bar was inserted in the entirely extrapleural tunnel.

Laparoscopic hepatojejunostomy for biliary atresia.

Purpose: The aim of this study was to evaluate the feasibility of laparoscopic hepatojejunostomy for types I and II biliary atresia (BA).

Background: Anorectal malformations (congenital absence of the anal opening) are among the most common pediatric surgical problems and carry a significant chronic morbidity.

Methods: Direct sequencing was used to screen 88 anorectal malformations patients for mutations and polymorphisms in SHH and GLI3. These genes were chosen according to the phenotype presented by mutant mice and their expression patterns.

Laparoscopic correction of biliary duct stenosis in choledochal cyst.

Background/purposes: Laparoscopy has been widely accepted as a technique for the excision of choledochal cyst, but there has been little experience using it as a therapeutic modality for hepatic duct stenosis. The aim of this study is to present our experiences in laparoscopic excision of biliary stenosis and Roux-en-Y reconstruction for patients with choledochal cysts.

Methods: Eight patients, 3 boys and 5 girls (ranged from 6 months to 12 years; median age, 3.

Mapping of a Hirschsprung's disease locus in 3p21.

Hirschsprung's disease (HSCR) is a congenital disorder in which ganglion cells are absent in variable portions of the lower digestive tract according to which patients are classified. The RET gene is the major HSCR gene, although reduced penetrance of RET mutations and variable expression of HSCR phenotype indicates that more than one gene is required. An unidentified RET-dependent modifier on 3p21 appears to be necessary for transmission of the short HSCR (S-HSCR) phenotype.
