    Purpose: This study aimed to evaluate the use of a transumbilical incision for infants and children, as well as neonates, with various intraabdominal conditions. Methods: A retrospective study of transumbilical incision surgery was performed between June 2007 and June 2013. Patients were divided into two groups: group 1 of neonates and group 2 of infants and children. All operations were performed via an upper circumumbilical incision. Results: Thirty-six patients (22 males, 14 females) were treated via a transumbilical incision, with 20 patients in group 1 and 16 patients in group 2. A transverse incision extension was needed for 1 case in group 1 (intestinal atresia complicated by meconium peritonitis) and 4 cases in group 2 (two with ileus owing to adhesive bands, 1 with malrotation, 1 with ectopic pancreatic tissue in the duodenum). In cases with a dilated intestinal wall or intraabdominal adhesions, an optional extension of the transverse incision might be required. Only 1 case with ileus in group 2 developed a wound infection that was treated by drainage. The postoperative cosmetic results were acceptable in all cases. Conclusion: The transumbilical incision yielded a sufficiently large surgical field, and the surgical condition was easily and directly viewed. In all 36 cases, an adequate operation was safely performed. This approach is a safe and effective method for various intraabdominal disorders in not only neonates but also infants and children, and leads to an imperceptible incision. (C) 2014 Elsevier Inc.

    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.

    The optimal management of microcystic lymphatic malformations (LMs) in children has not been established. We describe how we used the Ligasure (TM) Vessel Sealing System (LVSS) to achieve partial resection of refractory microcystic LMs in a 1-year-old boy. The child was admitted in respiratory distress caused by infection and swelling of cervical LMs. The LMs had been diagnosed prenatally, but had not decreased in size despite three treatments with OK-432 sclerotherapy. We performed direct dissection of the microcystic LMs using the LVSS with minimal intraoperative blood loss or lymphatic leakage. The LMs were resected as completely as possible without damage to the jugular vein or major nerves. His postoperative course was uneventful. Histological examination revealed complete sealing of the lymphovascular channels with obliterated lumens. Resection using the LVSS is effective and easy to perform for partial resection of microcystic LMs. We recommend the combination of initial OK-432 injection therapy and subsequent partial resection using the LVSS for refractory microcystic LMs.

    Introduction: 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. Methods: 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. Conclusion: 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. © 2013 Springer-Verlag Berlin Heidelberg.

    Aim Assisted reproductive technology (ART) has increased the incidences of multiple gestations and low birth weights, which frequently warrant pediatric surgery. ART may have also increased the rate of birth defects. In this study, we aimed to determine whether infants conceived after ART required neonatal surgery more frequently compared with naturally conceived infants. Material and Methods Our study population comprised 1891 infants (160 ART (+) and 1731 ART ()) who were admitted to our neonatal intensive care unit during a 5-year period (January 2006December 2010); of these, 198 infants (9 ART (+) and 189 ART ()), with diseases requiring surgery, were referred to pediatric surgeons (consultation cases). We examined the following: (i) factors potentially increasing the requirement for surgery; (ii) frequency of birth defects; and (iii) maternal factors that may increase the need for surgery. Results A significantly higher incidence of multiple gestation and low birth weight was observed in the ART (+) group than the ART () group. However, ART did not yield a higher rate of surgery and birth defects: overall, the rate of surgery was 4% (7/160) in the ART (+) group and 8% (143/1731) in the ART () group. Of 198 consultation cases, the percentage of infants actually requiring surgery was approximately the same in the ART (+) group (7/9 [78%]) and the ART () group (143/189 [76%]). Conclusion Infants conceived after ART comprised a small proportion of neonatal surgery cases, and did not require surgery more frequently.

    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.

    A mesenchymal hamartoma of the chest wall is a rare benign tumor. Each case has a different clinical course as well as different radiological imaging findings, and various histopathological diagnoses. In addition, mesenchymal hamartoma is sometimes mistaken for a malignant tumor. This report presents a neonatal case of mesenchymal hamartoma of the bilateral chest wall.
