    English, Scientific journal, The α-fetoprotein (AFP) level is a sensitive biomarker of active hepatoblastoma (HB). This study aimed to clarify whether the Lens culinaris agglutinin A-reactive fraction of AFP (AFP-L3) after complete resection is a prognostic predictor of HB recurrence. Fourteen HB patients who underwent complete resection of HB were divided into the recurrence group (RG, n=4) and the non-recurrence group (NRG, n=10). The AFP level and AFP-L3 before and after radical surgery were compared between the 2 groups. There was no significant difference in AFP levels in the early postoperative period between the 2 groups (P=0.54), and AFP was not an early prognostic factor for HB recurrence. At 2 months after surgery, the AFP-L3 fell below the detection limit only in the NRG (7/10 cases) (NRG=70.0% vs. RG=0%, P=0.03). In addition, there were some cases of recurrence in those whose AFP level decreased to the normal range, but none in those whose AFP-L3 fell below the detection limit. In conclusion, the AFP-L3 decreased earlier than did the AFP level; thus, the AFP-L3 after complete resection may be a predictor for HB recurrence.
  • Hemi-Clamshell Approach for Fetal Lung Interstitial Tumor Resection in a Neonate: A Case Report.
    Yasuhiro Kuroda, Hiroaki Fukuzawa, Insu Kawahara, Keiichi Morita
    European journal of pediatric surgery reports, 9, 1, e72-e75, Jan. 2021, [International Magazine]
    English, Fetal lung interstitial tumor (FLIT) is a rare primary lung mass in neonates. Classical incisions, such as posterolateral thoracotomy or median sternotomy, do not provide optimal exposure of the operative field for the resection of pediatric thoracic giant tumors. Herein, we report a rare case of a FLIT in a full-term male neonate, with complete resection achieved using a hemi-clamshell approach, which provided the required visualization of the operative field. The neonate was transferred to our hospital because of mild respiratory distress, which developed 18-hour after normal vaginal delivery. A mass in his right chest, without a midline shift, was observed on chest radiographs. Computed tomography showed a well-circumscribed solid anterior cervicothoracic mass, with a uniform density and no apparent cysts, diagnosed as a primary thoracic giant tumor. Once the patient was clinically stabilized, we proceeded with right upper lobectomy, using a hemi-clamshell approach, full sternotomy, and anterolateral thoracotomy, on postnatal day 22. Histopathologic examination revealed an 8.5 × 6.5 × 4.0 cm solid mass within the right upper lobe, which was diagnosed as a FLIT. His postoperative recovery was uneventful. The patient was followed up for 1 year, with no complaints or symptoms and no postoperative shoulder dysfunction. Gross total resection of primary thoracic giant tumors can be accomplished in neonates with optimal exposure of the chest cavity using a hemi-clamshell approach.

    English, Scientific journal, BACKGROUND: Intraperitoneal arterial hemorrhage without trauma is extremely rare. We report two infant cases of intraperitoneal arterial hemorrhage due to intestinal duplication. CASE PRESENTATION: In case 1, a 2-month-old girl experienced sudden intraperitoneal hemorrhage from the middle colic artery with no apparent trauma. Hemostasis was achieved with suturing of the hemorrhage point, but the cause of hemorrhage was still unknown. Computed tomography after the first operation revealed a duodenal duplication cyst and a pseudopancreatic cyst. Percutaneous drainage of the pseudopancreatic cyst was performed, and the contents had high pancreatic amylase. As the size of the duodenal duplication cyst also decreased with this drainage, we suspected that the duodenal duplication cyst was connected to the pseudopancreatic cyst and the arterial hemorrhage. We hypothesized that the pancreatic juice inside the duplication cyst leaked into the intraperitoneal cavity and caused rupture of the arterial wall. Therefore, marsupialization of the duodenal duplication was performed to evacuate the pancreatic juice contained in the cyst toward the native duodenum. The postoperative course was uneventful. In case 2, a 6-month-old boy experienced sudden intraperitoneal hemorrhage without trauma. The hemorrhage site was identified as the ileocecal artery, and hemostasis was achieved with sutures. Tissue near the hemorrhage point was biopsied, because the cause of arterial wall rupture was still unknown. The biopsied tissue was found to be intestinal mucosa. The patient had recurrent abdominal pain after the first operation, and computed tomography showed a duplication cyst located near the hemorrhage point. Therefore, we resected the intestinal duplication. Pathology results showed that the intestinal duplication contained intestinal mucosa, ectopic gastric mucosa, and pancreatic tissue. The postoperative course was uneventful. CONCLUSION: Intraperitoneal arterial hemorrhage without trauma is an extremely rare condition, and identifying its cause is difficult. To our knowledge, this is the first report of intraperitoneal arterial hemorrhage due to intestinal duplication. In cases of unexplained intraperitoneal arterial hemorrhage in infants, intestinal duplication near the hemorrhage point should be suspected.

    English, Scientific journal, PURPOSE: The aim of this study was to investigate risk factors for recurrence in the perineal canal (PC). METHODS: Patients with PC who underwent operations were enrolled in this study and were divided into recurrence and non-recurrence groups. Preoperative infection, the age at the operation, the presence of colostomy and the treatment procedure for fistula were retrospectively investigated. Regarding the treatment procedure for fistula, either closure of the rectal wall with stitches or ligation of fistula in the rectum was performed. These factors were compared between the two groups. RESULTS: Six of 17 patients with PC who underwent surgical treatment had recurrence. There were no significant differences in the incidence of preoperative infection, age at operation or presence of colostomy (p = 0.60, 0.38, 1.00, respectively). In the recurrence group, all patients were treated by closure of the rectal wall. In the non-recurrence group, five were treated by the closure of the rectal wall with stitches and six by ligation of the fistula. There was a significant association between recurrence and the treatment procedure for fistula (p = 0.04). CONCLUSION: Closure of the rectal wall with stitches is a risk factor for the recurrence of PC.

    English, Scientific journal, PURPOSE: A type IV laryngotracheoesophageal cleft (LTEC) is a very rare congenital malformation. Type IV LTEC that extends to the carina have poor prognosis and are difficult to manage. We present our experience with surgical repair in such a case using extracorporeal membranous oxygenation (ECMO). METHODS: A male infant, who was diagnosed with Goldenhar syndrome, showed severe dyspnea and dysphagia. Laryngoscopy indicated the presence of LTEC. The patient was transferred to our institute for radical operation 26 days after birth. Prior to surgery, a balloon catheter was inserted in the cardiac region of stomach through the lower esophagus to block air leakage, to maintain positive pressure ventilation. We also performed observations with a rigid bronchoscope to assess extent of the cleft, and diagnosed the patient with type IV LTEC. After bronchoscopy, we could intubate the tracheal tube just above the carina. Under ECMO, repair of the cleft was performed by an anterior approach via median sternotomy. RESULTS: The patient was intubated via nasotracheal tube and paralysis was maintained for 2 weeks, using a muscle relaxant for the first 3 days. Two weeks after surgery, rigid bronchoscopy showed that the repair had been completed, and the tracheal tube was successfully extubated without tracheotomy. CONCLUSIONS: Although insertion of a balloon catheter is a very simple method, it can separate the respiratory and digestive tracts. This method allowed for positive pressure ventilation and prevented displacement of the endotracheal tube until ECMO was established. As a result, we safely performed the operation and the post-operative course was excellent.

    English, Scientific journal, PURPOSE: The aim of this study was to confirm laryngotracheal growth and recurrent laryngeal nerve (RLN) preservation after partial cricotracheal resection (PCTR) in a growing rabbit model by performing the procedure in pediatric animals. METHODS: Six female Japanese white rabbits, 12 weeks of age, underwent PCTR. The course of the RLN was evaluated during surgery (n = 3). Endoscopic and histologic examinations were performed at 22 weeks of age (n = 6). Four non-operated rabbits, 22 weeks of age, underwent endoscopic and histologic examinations as controls. RESULTS: The RLN was preserved at the esophageal side and entered the larynx behind the cricothyroid joint after PCTR. Endoscopic examination showed normal vocal cord movements and the large reconstructed subglottis. Histologically, sufficient submucosal vessels and cartilage growth were identified at the reconstructed larynx. The median inside luminal area at the anastomotic site in the PCTR group was 24.8 mm2 (range 21.8-29.0 mm2), and that at the cricoid cartilage and trachea in the control group was 23.4 mm2 (range 20.0-26.6 mm2) and 25.6 mm2 (range 22.9-28.8 mm2), respectively. CONCLUSION: No interference with laryngotracheal growth was seen, and RLN preservation was confirmed after PCTR. Use of PCTR in the pediatric age group seems appropriate.

    English, Scientific journal, PURPOSE: This study aimed to investigate the clinical features and risk factors of bile duct perforation in pediatric congenital biliary dilatation (CBD) patients. METHODS: CBD patients, whose initial symptom was abdominal pain, were enrolled in this study and were divided into perforated and non-perforated groups. The clinical features of the perforated group were investigated. Moreover, the age at operation, sex, and morphologic features of the extrahepatic bile duct were compared between the groups. RESULTS: Fifteen cases of bile duct perforation (10.4%) were identified among the 144 CBD patients who had abdominal pain. Majority of bile duct perforation occurred in patients aged < 4 years. The median duration from onset of abdominal pain to bile duct perforation was 6 (4-14) days. Age at onset [< 4 years old; P = 0.02, OR 13.9, (1.663, 115.3)], shape of extrahepatic bile duct [non-cystic type; P = 0.009, OR 8.36, (1.683, 41.5)], and dilatation of the common channel [P = 0.02, OR 13.6, (1.651, 111.5)] were risk factors of bile duct perforation. CONCLUSIONS: Emergent bile duct drainage might be planned to prevent bile duct perforation if CBD patients have the abovementioned risk factors and experience persistent abdominal pain lasting for a few days from onset.

    Japanese, Purpose: In our department, we have applied conservative treatment of acute appendicitis in children. The purpose of this study was to determine the indications and limitations of the conservative treatment of acute appendicitis in children.
    Methods: We retrospectively reviewed the medical records of 53 patients treated conservatively for acute appendicitis in our institution between January 2012 and August 2014.
    Results: Of the 53 patients, 36 were treated successfully (successful group) and 17 were resistant to the conservative treatment (resistance group). On admission, the body temperature of the resistance group was significantly higher than that of the successful group (37.4 ± 0.7°C vs 38.2 ± 0.8°C, p = 0.01). The C-reactive protein (CRP) level was significantly higher in the resistance group (1.4 ± 1.7 mg/dl vs 9.7 ± 7.0 mg/dl, p < 0.01). Appendix diameter was significantly greater in the resistance group (8.4 ± 2.7 mm vs 11.3 ± 2.5 mm, p < 0.01), and fecaliths were more frequently observed in the resistance group (16.7% vs 76.5%, p < 0.01). The white blood cell (WBC) count 48 h after treatment was higher in the resistance group (6,988.9 ± 2,884.8/μl vs 11,741.2 ± 3,845/μl, p < 0.01). The recurrence rate was higher in the resistance group (8.3% vs 36.4%, p = 0.042). The cut-off values of the two groups 48 h after treatment were estimated as 9,650.0/μl for the WBC count and 6.67 mg/dl for the CRP level.
    Conclusions: When the WBC count is higher than 9,650.0/μl or the CRP level is higher than 6.67 mg/dl 48 h after treatment, we should attempt to change the strategy from conservative treatment to surgical treatment.

    J. Jpn. Soc. Pediatr. Surg., 51, 5, 868, 872, The Japanese Society of Pediatric Surgeons, 2015
    Japanese, Purpose: We assessed the validity of aggressive surgical intervention in the management of trisomy 13 and trisomy 18.Methods: The clinical records of 21 patients with trisomy 13 or 18 admitted to our neonatal intensive care unit between 2008 and 2014 were retrospectively analyzed.Results: All 21 patients were diagnosed as having some abnormalities, and 9 patients (42.9%) were diagnosed as having chromosomal anomalies prenatally. Eleven patients (52.4%) were diagnosed as having pediatric surgical diseases postnatally: intestinal malrotation, esophageal atresia, gastroesophageal reflux disease, diaphragmatic hernia, hepatoblastoma, anorectal malformation, omphalocele, and inguinal hernia. Two patients with intestinal malrotation and 1 patient with esophageal atresia had radical operation and have survived for 2–5 years at home. A patient with hepatoblastoma as well as congenital heart disease made the transition to palliative care. Three patients with poor prognosis underwent palliative procedure, and 2 patients died without undergoing surgical treatment. Tracheostomy for long-term endotracheal intubation was carried out in 4 patients. Cardiovascular surgery including intracardiac repair was performed in 3 patients. Heart disease in 20 patients (95.2%) was the major prognostic factor, and neonatal intensive care affected short-term mortality. Procedures by pediatric surgeons did not seem to have a direct effect on the patients' prognosis and did not disturb the time shared with their families.Conclusions: Recent reports focus on long-term survivors with trisomy 13 and trisomy 18 suggesting the necessity of appropriate treatment in accordance with individual condition. It is ethically reasonable that pediatric surgeons provide aggressive surgical intervention on the basis of objective medical evaluation.
