ABSTRACT
BACKGROUND: The purpose of this study is to assess the usefulness of continuous bowel decompression using an indwelling transanal tube (ITT) for preoperative management in infants with long-segment (L)- or total (T)-type Hirschsprung's disease (HD). CASE PRESENTATION: Between 2012 and 2015, seven patients with L- or T-type HD underwent preoperative bowel management by continuous bowel decompression using an ITT during waiting period for curative surgery. Continuous bowel decompression was done using an ITT, a 10-12F flexible dual lumen tube placed through the rectum up to the dilated colon under fluoroscopic guidance and secured to the bilateral buttocks. The ITT tips were located at least in a dilated colon or the cecum if there was no radiographic transitional zone. The ITT was left open for continuous drainage, and its patency was checked by regular suction until the curative operation. The patient status and complications of this preoperative management were reviewed retrospectively. RESULTS: The median duration of decompression management was 65 (17-137) days. During decompression period, neither abdominal distention, enterocolitis, nor other complications occurred and six patients could stay at home until the curative operation. The weight-for-age Z-score at curative surgery was the same as or higher than that at birth in five patients. ITT replacement was needed three times per patient on an average for accidental ITT removal, ITT stenosis, or ITT hardening. CONCLUSIONS: Bowel management by continuous bowel decompression using an ITT is easy, safe, and effective for preoperative management in patients with L- or T-type HD and may permit single-stage surgery rendering colostomy or enterostomy unnecessary.
ABSTRACT
PURPOSE: Pediatric surgeons currently engage in various abdominal vascular surgeries, which sometimes require vascular conduits or grafts. Herein, we report our experience with patients undergoing vascular reconstruction using a recanalized umbilical vein (rUV) and their long-term outcome. METHOD: Five patients with extrahepatic portal vein obstruction (EHPVO) underwent mesenterico-/porto-left portal vein (PV) bypass surgery using a short rUV conduit with an interposition vein graft. A sixth neonate with a huge hepatic tumor underwent PV reconstruction with anastomosis of rUV to the proximal PV stump following right hepatectomy with partial PV resection. A seventh patient underwent living donor liver transplantation for recurrent hepatoblastoma. The hepatic inferior vena cava (IVC) was resected because of tumor involvement and reconstructed by transposition of the infrahepatic IVC and interposition of rUV obtained from the donor liver graft. RESULTS: Sufficient flow through rUV was achieved and maintained in all patients without any complications during follow-up (0.7-6.9 years). Esophageal varices, splenomegaly, and other laboratory test abnormalities because of portal hypertension disappeared after surgery in patients with EHPVO. CONCLUSION: Our experience confirmed the usefulness and long-term patency of rUV as an entry to the intrahepatic PV and as a free vascular graft to reconstruct PV or IVC.

BACKGROUND: Very low-birthweight (VLBW) infants (VLBWI) are at increased risk for surgical intestinal disorders including necrotizing enterocolitis (NEC), focal intestinal perforation (FIP) and meconium-related ileus (MRI). The aim of this study was to identify disease-specific risk factors for surgical intestinal disorders in VLBWI. METHODS: A retrospective multicenter case-control study was conducted at 11 institutes. We reviewed VLBWI who underwent laparotomy for intestinal disorders including perforation and intractable bowel obstruction. The surgical disorders were classified into four categories (NEC, FIP, MRI, others) based on the macroscopic findings at operation. In order to identify risk factors, two matched controls for each subject were chosen based on gestational age and birthweight. OR and 95%CI were calculated using a conditional logistic regression model and a multivariate model. RESULTS: A total of 150 cases (NEC, n = 44; FIP, n = 47; MRI, n = 42; others, n = 17) and 293 controls were identified. The cases and controls were similar in terms of gestational age and birthweight (cases/controls, 26.7 ± 2.5/26.5 ± 2.6 weeks; 790 ± 256/795 ± 257 g). On multivariate modeling, disease-specific risk factors were as follows: female (OR, 0.23; 95%CI: 0.06-0.89), respiratory distress syndrome (OR, 35.7; 95%CI: 2.48-514) and patent ductus arteriosus (OR, 10.9; 95%CI: 1.51-79.3) for NEC; outborn delivery (OR, 5.47; 95%CI: 1.48-20.2) for FIP; and twin pregnancy (OR, 4.25; 95%CI: 1.06-17.1), PROM (OR, 6.85; 95%CI: 1.33-35.4) and maternal steroid (OR, 0.23; 95%CI: 0.07-0.79) for MRI. CONCLUSIONS: Different risk factors were identified for NEC, FIP and MRI, suggesting that each disease has a different etiology, and that different strategies are required to prevent these diseases.

PURPOSE: To demonstrate the outcome of external lengthening for long-gap esophageal atresia (LGEA) at our hospitals. METHODS: Five patients with LGEA underwent external lengthening between 2010 and 2014 (group A), and 11 patients with LGEA underwent other lengthening techniques between 1990 and 2011 (group B). We compared the procedure and outcome between these two groups. RESULTS: The mean birth weight was 2001 g in group A and 2485 g in group B (p = 0.06). The mean age at esophageal reconstruction was 28 days in group A and 227 days in group B (p = 0.03). Although primary esophageal anastomosis without myotomy was feasible in all patients in group A, a myotomy was needed for primary esophageal anastomosis in half of the patients in group B. Anastomotic leakage occurred in none in group A and in six patients in group B (p = 0.03). The mean age at the establishment of full oral feeding was 76 days in group A and 686 days in group B (p = 0.009). CONCLUSION: External traction for LGEA can effectively lengthen the esophagus to enable primary anastomosis at an earlier age. This may facilitate oral intake.

BACKGROUND: Surgical intestinal disorders, such as necrotizing enterocolitis (NEC), focal intestinal perforation (FIP), and meconium-related ileus (MRI), are serious morbidities in very low-birthweight infants (VLBWI). The aim of this study was to compare the composite outcomes of death or neurodevelopmental impairment (NDI) in VLBWI with surgical intestinal disorders and assess independent risk factors for death and NDI at 18 months of corrected age. METHODS: A retrospective matched-cohort study was conducted at 11 institutes. We included VLBWI who had undergone laparotomy for NEC, FIP, and MRI. Two control subjects were chosen for every surgical patient and matched for gestational age and birthweight to form the comparison group. Death and neurodevelopmental outcome at 18 months of corrected age were evaluated. RESULTS: The number of infants in the NEC, FIP, MRI, and control groups was 44, 47, 42, and 261, respectively. In-hospital mortality was higher in infants with NEC and MRI relative to those in the control group (P < 0.001). The incidence rate for NDI at 18 months of corrected age was higher in infants with MRI relative to those in the control group (P = 0.021). On logistic regression analysis, low gestational age, male sex, small for gestational age, intraventricular hemorrhage, and MRI were associated with increased risk of death or NDI at 18 months of corrected age. CONCLUSIONS: NEC and MRI were associated with in-hospital mortality, and MRI was associated with NDI or death at 18 months of corrected age.

Down syndrome is an autosomal chromosome disorder, characterized by intellectual disability and muscle hypotonia. Muscle hypotonia is observed from neonates to adulthood in Down syndrome patients, but muscle hypertonicity is extremely unusual in this syndrome. During a study period of nine years, we found three patients with severe spastic quadriplegia among 20 cases with Down syndrome and congenital duodenal stenosis/atresia (3/20). However, we could find no patient with spastic quadriplegia among 644 cases with Down syndrome without congenital duodenal stenosis/atresia during the same period (0/644, P < 0.05). Further, we did not find any cases with spastic quadriplegia among 17 patients with congenital duodenal stenosis/atresia without Down syndrome admitted during the same period to use as a control group (0/17, P < 0.05). Our results suggest that congenital duodenal stenosis/atresia is a potential risk factor for spastic quadriplegia in patients with Down syndrome. Long-term survival is improving, and the large majority of people with Down syndrome are expected to live well into adult life. Management and further study for the various problems, representing a low prevalence but serious and specific to patients with Down syndrome, are required to improve their quality of life.

We report a case of papillary carcinoma (PC) with extensive squamous metaplasia arising from a thyroglossal duct cyst (TDC) that required differential diagnosis from squamous cell carcinoma (SCC). An 11-year-old Japanese girl presented with a 9-month history of an anterior-midline neck mass that was clinically diagnosed as TDC. Open neck biopsy revealed nested proliferation of atypical squamous cells within the cystic structures, and SCC arising from TDC was initially suspected. Further examination, however, including immunohistochemistry, revealed the tumor to be of thyroid cell origin. The patient underwent wide local resection of the thyroglossal duct carcinoma by Sistrunk procedure and cervical lymph node dissection. Microscopically, the diagnosis was of PC with extensive squamous metaplasia and metastasis to the medial submandibular lymph node. Distinction of squamous metaplasia in PC from SCC is sometimes difficult, but has a significant effect on postoperative management.

PURPOSE: In 2006, The Japanese Society of Pediatric Endoscopic Surgeons devised a plan to develop a pediatric endoscopic surgical skill qualification (ESSQ) system. This system is controlled by The Japan Society for Endoscopic Surgery. The standard requirement for skills qualification is the ability of each applicant to complete common types of laparoscopic surgery. The main goal of the system is to decrease complications of laparoscopic surgery by evaluating the surgical skills of each applicant and subsequently certify surgeons with adequate skills to perform laparoscopic operations safely. METHODS: A committee of pediatric ESSQ created a checklist to assess the applicant's laparoscopic surgical skills. Skills are assessed in a double-blinded fashion by evaluating an unedited video recording of a fundoplication for pediatric gastroesophageal reflux disease. RESULTS: The initial pediatric ESSQ system was started in 2008. In 2008 and 2009, respectively, 9 out of 17 (53%) and 6 out of 12 (50%) applicants were certified as expert pediatric laparoscopic surgeons. CONCLUSIONS: Our ultimate goal is to provide safe and appropriate pediatric minimally invasive procedures and to avoid severe complications. To prove the predictive validity of this system, a survey of the outcomes of operations performed by certified pediatric surgeons is required.

PURPOSE: Mesenterico-left portal vein (meso-Rex) bypass is as an effective modality for restoring intrahepatic portal perfusion in patients with extrahepatic portal vein obstruction. Achieving sufficient patency is difficult with end-to-side anastomosis of a bypass graft to a small or hypoplastic left portal vein in the Rex recessus. Here, we describe the use of a recanalized umbilical vein in the round ligament as a conduit for bypass construction in two patients. METHODS: Case 1 was an 11-year-old boy diagnosed with rupture of the esophageal varices and hypersplenism due to congenital extrahepatic portal hypertension. Because of persistent hypersplenism and thrombocytopenia, he underwent meso-Rex bypassing with a left iliac vein graft interposed between the umbilical vein and the superior mesenteric vein. Case 2 was a neonate with a large hepatic tumor (mesenchymal hamartoma) that developed abdominal compartment syndrome at birth. The tumor was removed by right hepatectomy with excision of the portal vein bifurcation at 3 days of age. Porto-Rex bypassing was accomplished by end-to-end anastomosis between the portal vein trunk and the umbilical vein. RESULTS: Sufficient hepatopetal portal flow through the umbilical vein was achieved in both patients and maintained for over 16 and 13 months, respectively. Although hypersplenism remained in Case 1, intrahepatic portal vein branches gradually widened and the cavernoma in the hepatic hilum disappeared within 2 months. Neither patient had symptoms or signs of portal hypertension at the most recent follow-up. CONCLUSION: Using the umbilical vein as a vein conduit may facilitate construction of a meso/porto-Rex bypass and restore intrahepatic portal vein perfusion in patients with extrahepatic portal vein obstruction.

Ingestion of a button battery has been considered a serious problem, causing necrosis and perforation, when impacted in the esophagus. However, such batteries in the stomach rarely cause any harm to the gastric wall, which is regarded as evidence supporting the use of conservative treatment. We present the rare case of a 3-month-old infant with severe gastric wall injury caused by a button battery lodged in the stomach. The present case suggests that button batteries located in the stomach should be removed as soon as possible, especially in infants.

OBJECTIVE: Sequential strategies combining the Kasai operation as a first-line treatment and liver transplantation as a second-line option, if necessary, have been accepted for patients with biliary atresia (BA). To understand the role of the Kasai operation in the treatment of BA, it is necessary to analyze the long-term outcome of the operation alone and to evaluate the present status of survivors retaining their native livers. MATERIALS AND METHODS: A retrospective chart review was carried out for a group of 80 patients who had undergone the Kasai operation between 1970 and 1986 at the Kanagawa Children's Medical Center. RESULTS: The 5-, 10-, and 20-year survival rates of patients with their native livers were 63%, 54%, and 44%, respectively. The survival rates varied significantly depending on the type of BA, age at initial Kasai operation, era of surgery, and surgical method. By age 20, nearly half of the adult survivors had already developed liver cirrhosis and its sequelae. Episodes of cholangitis and gastrointestinal bleeding occurred after 20 years of age in 37% and 17% of the adult patients, respectively, and 20% of the adult patients died of liver failure or underwent living-related partial liver transplantation in their 20s. Five female patients gave birth to a total of 9 children, and 1 male patient fathered a child. CONCLUSIONS: Although increasing numbers of patients with BA survive 20 years or more after the Kasai operation, meticulous lifelong postoperative care should be continued for the survivors because of the possibility of hepatic deterioration.

We report the fourth example of a patient with germline partial trisomy of 2p21-pter and congenital neuroblastoma. The male infant had a dysmorphic facial expression and presented with congenital heart disease, supernumerary nipples, hypospadias, shawl scrotum, hemilateral persistent hyperplastic primary vitreous, and neuroblastoma. His germline karyotype of 46,XY,der(8)t(2;8)(p21;p23.2) was inherited from a maternal-balanced translocation, which indicates that the proto-oncogene MYCN region of 2p24.3 is tripicated in germline cells. A cytogenetic study of the biopsied tumor cells did not show MYCN amplification, but the DNA index was 2.4 and histologic fluorescent in situ hybridization analysis indicated somatic mutation with near-pentaploidy of the tumor cells. This could be an alternative mechanism of MYCN activation in the process of the tumorigenesis of neuroblastoma.

A case of pericardial hemangioma is described which was resected in the neonatal period due to its effect on the cardiopulmonary system. Preoperative differential diagnosis of a teratoma was difficult. Surgical extirpation resulted in massive bleeding and postoperative bronchomalacia. These complications suggest that we should choose a conservative therapy as often as possible.

PURPOSE: The authors evaluated the validity of the Pediatric End-Stage Liver Disease (PELD) Risk Scoring System as a severity index for patients with biliary atresia. METHODS: Individual hospital records of 104 patients with biliary atresia were reviewed at our institution and divided into 3 groups: nontransplant survivors (n = 61), nontransplant deaths (n = 17), and transplant patients (n = 26). PELD risk scores were calculated according to Wiesner et al, multiplied by 10, and rounded to the nearest integer, as is done in determining model of end-stage liver disease (MELD) scores. RESULTS: The PELD scores showed a significant difference between nontransplant survivors (range, -21 to 15) and dying nontransplant patients during their last few months of life (range, 2 to 40). No survivors except those below the age of one year recorded scores above 10. Transplant patients had higher scores (range, -5 to 37) before transplantation than nontransplant survivors. However, the scores were not elevated in elderly patients with intractable cholangitis, fulminant variceal rupture, and hepatopulmonary syndrome. CONCLUSIONS: PELD profiling is a useful scoring system for selecting patients with the most severe liver dysfunction caused by biliary atresia. However, we advise caution in using this system for patients under the age of 1 year and for older patients with long-term complications.
