    Purpose: Congenital tracheal stenosis (CTS) is rare and challenging. Complete tracheal rings cause a wide spectrum of airway-obstructing lesions and varying degrees of respiratory distress. Although surgical reconstruction is the primary option for symptomatic CTS, sometimes an appropriate management strategy may be difficult due to other anomalies. We aimed to identify pitfalls in the management of CTS. Methods: We retrospectively reviewed the records of patients with CTS during the last 10 years in our institution. Results: Sixteen pediatric patients were diagnosed with CTS. Of the 16 patients, 12 (75.0%) had cardiovascular anomalies including seven left pulmonary artery sling. Six patients with dyspnoea caused by CTS and three patients with difficult intubations due to CTS underwent tracheoplasty. Four patients underwent only cardiovascular surgery without tracheoplasty. Three asymptomatic patients were followed up without undergoing any surgical procedure. We repeatedly discussed management of four patients with especially complex pathophysiology at multidisciplinary meetings. Right ventricular outflow tract obstruction, tracheobronchial malacia, increased pulmonary blood flow, and pulmonary aspiration due to gastroesophageal reflux presumably accounted for their severe respiratory distress, and we forewent their tracheal reconstruction. Conclusion: The management of CTS should be individualized, and conservative management is a feasible option in selected cases.

    Covered cloacal exstrophy (CCE) is extremely rare condition. In patients with a single perineal orifice and no pubic bone separation, it is very difficult to suspect and/or diagnose CCE based on external signs alone. We present the case of a 2-month-old girl diagnosed with CCE based on cystography, ileostomy contrast study and cystoscopy.

    【目的】当科では小児急性虫垂炎に対し,保存的治療を第一選択としている.今回,我々の治療経験から小児急性虫垂炎に対する保存的治療の適応および限界について検討した.<br>【方法】2012 年1 月から2014 年8 月までに急性虫垂炎の診断で入院し抗菌薬を用いた保存的治療を行った53 症例を対象とし,保存的治療奏効群と保存的治療抵抗群に分けて比較検討した.<br>【結果】53 例中,奏効群は36 例,抵抗群は17 例.入院時体温は奏効群が37.4±0.7°C,抵抗群が38.2±0.8°C で抵抗群において高かった(p=0.01).入院時血液検査所見では,CRP が奏効群1.4±1.7 mg/dl,抵抗群9.7±7.0 mg/dl と,抵抗群で高値であった(p<0.01).画像所見では,虫垂最大径が奏効群8.4±2.7 mm,抵抗群11.3±2.5 mm と抵抗群で有意に腫大していた(p<0.01).糞石は奏効群の16.7%(6/36 例),抵抗群の76.5%(13/17 例)に認めていた(p<0.01).治療開始後24 から48 時間での白血球数は奏効群6,988.9±2,884.8/μl,抵抗群11,741.2±3,845/μl と,抵抗群で高値であった(p<0.01).再発率は奏効群8.3%に対し,抵抗群では36.4%と高率であった(p=0.042).治療開始から48 時間での2 群のカットオフ値は,白血球数9,650.0/μl,CRP 値が6.67 mg/dl と推定された.<br>【結論】治療後48 時間において白血球数が9,650.0/μl またはCRP 値が6.67 mg/dl を超える症例では早期の外科治療を検討すべきである.

    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.
