A case of biliary atresia with pancreaticobiliary maljunction.

Background: The pathogenesis of biliary atresia (BA) is still unknown. There are several reports on the etiology of BA, including pancreaticobiliary maljunction (PBM). We experienced a case of Kasai type IIIa BA with PBM, in which we found elevation of pancreatic enzymes in the gallbladder.

Predictive factor for intraoperative tumor rupture of Wilms tumor.

Purpose: For Wilms tumor, intraoperative tumor rupture with wide tumor spillage during surgical manipulation raises the classification to stage 3. Then, postoperative chemotherapy must be more intensive, and abdominal radiotherapy is added. Therefore, intraoperative tumor rupture should be avoided if possible.

Evaluation of the intraoperative risk factors for esophageal anastomotic complications after primary repair of esophageal atresia with tracheoesophageal fistula.

Purpose: The aim of this study is to identify the risk factors for esophageal anastomotic stricture (EAS) and/or anastomotic leakage (EAL) after primary repair of esophageal atresia with tracheoesophageal fistula (EA/TEF) in infants.

Methods: A retrospective chart review of 52 patients with congenital EA/TEF between January 2000 and December 2015 was conducted. Univariate and multivariate analyses were performed to identify the risk factors for anastomotic complications.

Surgical intervention strategies for congenital tracheal stenosis associated with a tracheal bronchus based on the location of stenosis.

Purpose: The aim of this study was to determine the appropriate surgical intervention strategies for congenital tracheal stenosis (CTS) associated with a tracheal bronchus based on the location of stenosis.

Methods: The medical records of 13 pediatric patients with CTS associated with a tracheal bronchus at a single institution between January 2006 and December 2015 were retrospectively reviewed.

Results: Type 1: tracheal stenosis above the right upper lobe bronchus (RULB) (n = 1).
