Intrahepatic bile duct (IHBD) stones are one of the most complicated morbidities that occur after Roux-en-Y hepaticojejunostomy (RYH); however, the optimal therapeutic approach is controversial.Double-balloon enteroscopy (DBE) has been widely and frequently performed even in pediatric patients. We herein report the successful management of IHBD stones by biliary lithotripsy using DBE after RYH for a choledochal cyst (CC). DBE has made it possible to perform endoscopic therapeutic intervention, including balloon dilatation of an anastomotic stricture and removal of IHBD stones, without any major complications.DBE is a less invasive and safe treatment method for IHBD stones in pediatric patients, which is capable of reaching the bilioenteric anastomosis after RYH for CC.

Nonoperative management is acceptable treatment for minor pancreatic injuries. However, management of major pancreatic duct injury in children remains controversial. We present our experience in treating isolated pancreatic duct injury. We describe the cases of three male patients treated for complete pancreatic duct disruption in the past 5 years at our institution. We performed pancreatic duct repair to avoid distal pancreatectomy and to maintain normal pancreatic function. All patients underwent enhanced computed tomography and endoscopic retrograde cholangiopancreatography in the early period. The injuries were classified as grade III according to the American Association for the Surgery of Trauma classification. In two cases, we performed end-to-end anastomosis of the pancreatic duct during the delayed period. In the third case, we placed a stent across the disruption to the distal pancreatic duct. The patients’ postoperative courses were uneventful, and the average hospitalization was 25.6 days after the procedure. At a median follow-up of 36 months (range 14–54 months), all patients remain asymptomatic, with normal pancreatic function, but with persistent distal pancreatic duct dilatation. We suggest that distal pancreatectomy should not be routinely performed in patients with isolated pancreatic duct injury.

Neonates with congenital tracheal stenosis (CTS) sometimes develop respiratory distress and may be difficult to intubate. We used balloon tracheoplasty with a rigid bronchoscope for emergency airway management in neonates with symptomatic CTS. Herein, we describe the balloon tracheoplasty procedure and the early outcomes following its use as the initial treatment of neonatal symptomatic CTS. We performed a retrospective analysis of five neonates with CTS who were initially treated with balloon tracheoplasty at our institution from January 2010 to December 2013. Five patients with a mean birthweight of 2,117 g were treated during the study period. Of these, four developed respiratory distress after birth, and all patients had difficult intubations. In all five patients, definitive diagnosis of CTS was made by rigid bronchoscopy and 3-dimensional reconstruction scan. A total of nine balloon dilatations were performed in five patients. Following balloon tracheoplasty, two patients were extubated, one was extubated after resection and end-to-end anastomosis following initial balloon dilatation, and one remained hospitalized with tracheostomy for tracheomalacia. The remaining patient died from tracheal bleeding associated with congenital heart disease. Although our sample size was small, balloon tracheoplasty is a potentially effective initial treatment for selected cases with neonatal symptomatic CTS.

Blunt trauma to the abdomen accounts for the majority of abdominal injuries in children. Pancreatic injury is the fourth most common solid organ injury, following injuries to the spleen, liver and kidneys. The most common complications are the formation of pancreatic fistulae, pancreatitis and the development of pancreatic pseudocysts, which usually present several weeks after injury. The nonoperative management of minor pancreatic injury is well accepted; however, the treatment of more serious pancreatic injuries with capsular, ductal or parenchymal disruption in pediatric patients remains controversial. Based on the data presented in this literature review, although children with pancreatic injuries (without ductal disruption) do not appear to suffer increased morbidity following conservative management, patients with ductal disruption may benefit from operative intervention.

Double-balloon enteroscopy (DBE) is a useful and feasible modality for evaluating small intestinal lesions, even in children. DBE makes it possible to perform biopsy, diagnosis, polypectomy and endoscopic therapies including hemostasis, tattooing and clipping of the small intestinal lesions. However, endoscopic procedures in the small intestines of children are more difficult than in adults, because the intestinal wall is thin and the lumen is narrow. A novel hybrid treatment was developed using DBE for small bowel lesions combined with transumbilical minimal incision surgery. This hybrid treatment is safe, effective, provides excellent cosmetic results and can be used as an alternative for traditional open laparotomy or endoscopic surgery.
