Abstract
BACKGROUND Accessory scrotum is a congenital scrotal anomaly that is usually located anterior to the anus and frequently presents with a lipoma in a bead-like shape. Herein, we present an unusual case of an accessory scrotum with a lipoma connected by a narrow stalk and located posterior to the anus. CASE PRESENTATION A 1-month-old boy was referred to our hospital for a perineal mass present at birth. He was born at 37 weeks and 2 days, with a birth weight of 2962 g. No abnormalities occurred during the perinatal period, and the birth was uneventful. The mass had an unusual shape, comprising two masses connected by a narrow stalk. The base of the mass was posterior to the anus and was connected to the rectal mucosa. The proximal mass was elastic and soft without skinfolds, whereas the distal mass was elastic and soft with a scrotum-like skinfolds. Magnetic resonance imaging showed no spina bifida. High-intensity adipose tissues in both masses and low-intensity vessels or fibrous stroma in cord-like structures between the two masses were found on T2-weighted images. At 3 months of age, the patient underwent resection in the prone jackknife position. No tumorous lesions were connected to the mass on the rectal and coccyx sides, and the mass was completely removed, preserving the anal sphincter. Histologically, the distal mass had characteristics of a scrotum, whereas the proximal mass was exclusively a lipoma. The connecting stalk had normal skin structures and a blood vessel with parallel-running nerve bundles. The postoperative course was uneventful, and the patient was discharged on postoperative day 6. CONCLUSIONS This case of accessory scrotum was unusual in its location and the presence of a stalk connecting the accessory scrotum and lipoma. The mechanism underlying accessory scrotum development remains unclear, and our report may impact the discourse regarding the embryological development of the accessory scrotum.

Abstract
The COL4A1 (collagen Type 4 alpha1) pathogenic variant is associated with porencephaly and schizencephaly and accounts for approximately 20% of these patients. This gene variant leads to systemic microvasculopathy, which manifests as brain, ocular, renal, and muscular disorders. However, only a few patients with surgical interventions have been reported and the potential surgical risks are unknown. Here, we present the cases of two female patients between 7 and 8 years of age who were diagnosed with the COL4A1 variant and underwent laparoscopy-assisted percutaneous endoscopic gastrostomy (LAPEG) for oral dysphagia. Their primary brain lesions were caused by porencephaly and paralysis, which are caused by multiple cerebral hemorrhages and infarctions, and both patients had refractory epileptic complications. Although LAPEG was successfully performed in both patients without any intraoperative complications, one patient developed alveolar hemorrhage postoperatively and required mechanical ventilation. Thus, careful perioperative management of patients with the COL4A1 variant is important.

Abstract
Background Duplication cysts close to the ileocecal valve are usually treated with ileocecal resection. However, loss of the ileocecal valve will lead to problems, especially in infants. Mucosectomy of the cyst would be a better alternative that preserves the ileocecal valve. We report two cases of duplication cyst in the terminal ileum successfully treated with mucosectomy. Case presentation Case 1. A 3-month-old boy with bilious emesis and abdominal distention was referred to our hospital with a diagnosis of small bowel obstruction caused by an abdominal cyst. Computed tomography revealed a cystic mass compressing the terminal ileum and causing mechanical small bowel obstruction. His general condition deteriorated quickly; emergency laparotomy was performed. Although the small intestines were dilated and partially twisted, there was no necrosis. Following intestinal decompression, a cystic mass adjacent to the terminal ileum was confirmed on the mesenteric side. Cyst mucosectomy was performed to preserve the ileocecal valve. Case 2. A 5-month-old boy with sudden onset of hematochezia was referred to our hospital with a diagnosis of intussusception. Following unsuccessful contrast enemas, emergency surgery was performed. A cystic mass adjacent to the terminal ileum was confirmed; there was no intussusception. Cyst mucosectomy was performed. Both patients had an uneventful postoperative course. Conclusions Cyst mucosectomy, which preserves the ileocecal valve, is safe and effective for treating duplication cysts in the terminal ileum.

Abstract
PURPOSE Thoracoscopic repair (TR) of congenital diaphragmatic hernia (CDH) is associated with a higher recurrence rate than the conventional open method. We evaluated the effectiveness of our strategy for quality improvement, named "tension-free TR of CDH". METHODS The subjects of this retrospective analysis were 11 consecutive patients with CDH who underwent TR at our hospital between 2017 and 2021. Tension-free TR of CDH included the proactive use of an oversized patch for dome-shaped reconstruction and gapless suturing. We developed a percutaneous extracorporeal closure technique for secure suturing using a commercially available needle. RESULTS Patch repair was performed in 8 (73%) patients and none required conversion to open surgery because of technical difficulties. Recurrence developed in one patient (9%), who underwent successful reoperation via TR. All patients had an uneventful postoperative course. CONCLUSION Tension-free TR combined with extracorporeal closure could reduce the difficulty of suturing and the risk of recurrence of CDH.

Abstract
Background: Hydrocele of the canal of Nuck (HCN) is a rare cause of inguinal swelling in women. The optimal surgical procedure for HCN in children remains unclear. To assess the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) for HCN in a pediatric population, a retrospective study was conducted. In addition, to clarify the pathogenesis of HCN, we assessed the morphological findings of the internal inguinal ring (IIR). Materials and Methods: We retrospectively analyzed 10 consecutive female patients with HCN who underwent LPEC at our hospital between January 2010 and May 2020. Age, operative time, and complications were recorded. Concerning the findings of the IIR, we classified the morphological features as follows: Type 1 (flat), Type 2 (narrow patent processus vaginalis [PPV] with a peritoneal veil), and Type 3 (widely opening PPV). Results: The median age of patients who underwent LPEC was 3 (1-12) years. Although 2 patients showed contralateral inguinal hernia (IH), there were no cases of ipsilateral IH. All patients showed ipsilateral PPV, and the morphological features of the IIR were mostly classified as Type 3 (70%). In total, 6 of 8 HCN cases without preoperatively diagnosed contralateral IH had contralateral PPV (75%), and all were closed by LPEC. All operations were accomplished laparoscopically, and the postoperative course was uncomplicated, with no recurrences observed during the study period. Conclusions: LPEC is a safe and simple surgical approach to repair the HCN in children with minimal complications.

Abstract
Hepatopulmonary syndrome (HPS) is a disease of gas exchange caused by intrapulmonary shunting secondary to liver disease-associated intrapulmonary vascular dilation. HPS is characterized by the triad of cirrhosis, chronic liver disease, or portosystemic shunting (PSS); arterial hypoxemia; and intrapulmonary arteriovenous shunting in the absence of a primary cardiopulmonary anomaly. We encountered a rare case of HPS without liver disease or PSS. The patient was an 8-year-old girl who underwent living donor liver transplantation (LDLT) shortly after developing fulminant hepatitis at 11 months of her age. Eight years after LDLT, hypoxemia and shortness of breath developed. The shunt ratio on 99mTc-macroaggregated albumin (MAA) lung perfusion scintigraphy (99mTc-MAA lung scan) was 32%. The patient had no cardiopulmonary disease, so we diagnosed her illness as HPS. We did not find cirrhosis, chronic liver disease, or PSS as a cause of HPS. We thought the graft was the cause of HPS. A second transplantation was planned. One year after the diagnosis of HPS, the shunt ratio on 99mTc-MAA lung scan worsened to 42%, digital clubbing appeared, and hypoxemia was worsening. Thus, we performed a second LDLT. After LDLT the shunt ratio on 99mTc-MAA lung scan normalized (6%) and cyanosis resolved. We determined that the graft was the cause of HPS; the typical causes of HPS were not clearly revealed in the histologic examination of the second liver explant. Acute rejection occurred twice after LDLT, so we speculated that HPS occurred because the graft became stressed over the long term.

Abstract
Background Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of genetic autosomal recessive diseases that cause severe cholestasis, which progresses to cirrhosis and liver failure, in infancy or early childhood. We herein report the clinical outcomes of surgical management in patients with four types of PFIC. Case presentation Six patients diagnosed with PFIC who underwent surgical treatment between 1998 and 2020 at our institution were retrospectively assessed. Living-donor liver transplantation (LDLT) was performed in 5 patients with PFIC. The median age at LDLT was 4.8 (range: 1.9–11.4) years. One patient each with familial intrahepatic cholestasis 1 (FIC1) deficiency and bile salt export pump (BSEP) deficiency died after LDLT, and the four remaining patients, one each with deficiency of FIC1, BSEP, multidrug resistance protein 3 (MDR3), and tight junction protein 2 (TJP2), survived. One FIC1 deficiency recipient underwent LDLT secondary to deterioration of liver function, following infectious enteritis. Although he underwent LDLT accompanied by total external biliary diversion, the patient died because of PFIC-related complications. The other patient with FIC1 deficiency had intractable pruritus and underwent partial internal biliary diversion (PIBD) at 9.8 years of age, pruritus largely resolved after PIBD. One BSEP deficiency recipient, who had severe graft damage, experienced recurrence of cholestasis due to the development of antibodies against BSEP after LDLT, and eventually died due to graft failure. The other patient with BSEP deficiency recovered well after LDLT and there was no evidence of posttransplant recurrence of cholestasis. In contrast, recipients with MDR3 or TJP2 deficiency showed good courses and outcomes after LDLT. Conclusions Although LDLT was considered an effective treatment for PFIC, the clinical courses and outcomes after LDLT were still inadequate in patients with FIC1 and BSEP deficiency. LDLT accompanied by total biliary diversion may not be as effective for patients with FIC1 deficiency.

Abstract
PURPOSE Portoenterostomy is the standard treatment for biliary atresia (BA) that reduces jaundice in two thirds of cases. However, progressive liver fibrosis is common, leading to cirrhosis in most patients. Autotaxin is a new marker for the progression of hepatic fibrosis. We examined the relationship between serum autotaxin levels and liver histological findings in patients with BA. METHODS BA patients with native livers were identified in our hospital. Patients underwent protocol liver biopsies every 1 to 5 years, and liver fibrosis was evaluated based on the METAVIR score. Serum autotaxin levels were compared with the last available pathological findings. RESULTS Thirty-five patients were included and the median age was 10.6 years. Serum autotaxin levels was median 1.6 mg/L. The mean autotaxin level was 1.08 mg/L in F0, 1.07 mg/L in F1, 0.95 mg/L in F2, 2.17 mg/L in F3, and 2.50 mg/L in F4; it was significantly higher in F4 than in F0-F2 (P<0.0024). For predicting cirrhosis (F4) and advanced liver fibrosis (≥F3), autotaxin had the almost same areas under the curve (AUCs 0.78 and 0.90, respectively) as well as M2BPGi. CONCLUSION Autotaxin levels could be used to evaluate the status of native liver fibrosis.

Abstract
Right aortic arch (RAA) is one of congenital cardiovascular anomalies associated with esophageal atresia (EA). The surgical treatment for EA with RAA is still challenging. Although most pediatric surgeons are familiar with the right-sided approach, the division of the tracheoesophageal fistula and the anastomosis of the esophagus through right thorax are often difficult in cases of RAA. There are a few reports on thoracoscopic repair for EA with RAA. We report a case of EA with RAA treated by left-sided thoracoscopic approach. With left-sided thoracoscopic approach, identification and anastomosis of the esophagus could be safely performed without obstruction by the right-sided descending aorta. There was no leakage or stricture. Thoracoscopic repair of EA with RAA through the left thorax is feasible and safe without obstruction by the right-sided descending aorta.

Abstract
Background Congenital pyloric atresia (CPA) is a rare gastrointestinal anomaly frequently associated with epidermolysis bullosa (EB). Although the complications of familial isolated CPA are minor, delays in diagnosis can increase the chances of morbidity. Case presentation Three female infants born to a Japanese mother presented with CPA at birth. There was no consanguinity between the parents, and the spacing between pregnancies was 2 years in each case. All 3 siblings had a prenatal diagnosis of CPA owing to polyhydramnios and a dilated stomach, without dilatation of the rest of the gastrointestinal tract. All patients underwent reconstructive surgeries for establishing bowel continuity (Case 1, pyloromyotomy; Case 2, gastroduodenostomy in a diamond fashion; and Case 3, gastroduodenostomy in a side-to-side fashion) soon after birth. Their postoperative courses were uneventful, and they grew up healthily, without any complications. Conclusion Fetal ultrasonography is useful for diagnosing CPA prenatally. Successful prenatal diagnosis can lead to timely intervention after birth.

Abstract
Background and Aims: We performed thoracoscopic costal cartilage excision (TCCE) combined with the Nuss procedure to correct asymmetrical pectus excavatum (PE). We reviewed the efficacy of combined TCCE and Nuss procedure for asymmetric PE. Patients and Methods: Overall, 8 patients with asymmetrical PE underwent TCCE with the Nuss procedure. The Haller index, asymmetry index, and angle of sternal rotation were calculated using preoperative computed tomography. The procedure was performed using bilateral 2.5-cm incisions at the same level of the deepest chest wall depression. The most depressed three to four costal cartilages were partially resected through a right mini-thoracotomy. Subsequently, one or two titanium bars were implanted and secured with stabilizers. The cosmetic outcome was evaluated on the following four ratings: excellent, good, fair, and failure ( = recurrence). Results: The median age at surgery was 14.5 years (8-20 years). The number of bars was one in 3 cases and two in 5 cases. The preoperative Haller index, asymmetry index, and angle of sternal rotation were 4.3 (3.5-5.9), 1.15 (1.04-1.26), and 21.5° (15°-31°), respectively; 2 patients had scoliosis before the Nuss procedure. Complications included surgical site infection and hemothorax. Median follow-up time was 25.5 months (3-63). Bars were removed in 3 patients, 3 years postoperatively. Cosmetic results were excellent, 4; good, 2; fair, 1; failure, 1. Both patients with scoliosis had poor outcomes (fair, 1; failure, 1). Conclusions: Combined TCCE with Nuss procedure is considered safe and effective for patients with asymmetrical PE. Careful long-term follow-up is required, especially in cases with scoliosis.

Abstract
PURPOSE To date, there is no compelling evidence of the optimal timing of surgery for congenital diaphragmatic hernia (CDH). This study aimed to establish the optimal timing of surgery in neonates with isolated left-sided CDH. METHODS This multicenter cohort study enrolled 276 patients with isolated left-sided CDH at 15 institutions. Based on the timing of surgery, the patients were classified into four groups [< 24 h (G1), 24-47 h (G2), 48-71 h (G3), and ≥ 72 h (G4)]. The clinical outcomes were compared among the groups using a logistic regression model, after adjusting for potential confounders, such as disease severity. RESULTS Multivariate analyses showed that G2 also had a lower mortality rate than the other groups. In mild and severe cases, there were no significant differences in mortality across the four groups. In moderate cases, G2 resulted in significantly increased survival rates, compared with G1. CONCLUSION The study results suggest that surgery within 24 h of birth is not recommended for patients with moderate severity CDH, that there is no benefit in the delay of surgery for more than 72 h in mild severity CDH patients, and that there is no definite optimal time to perform surgery in severe cases of CDH.

Abstract
Background: The Japanese endoscopic surgical skill qualification system (ESSQS) in pediatric surgery was started 10 years ago to encourage safe and appropriate pediatric minimally invasive procedures and avoid severe complications. The present study investigated the impact of the ESSQS on the incidence of serious complications in the field of pediatric endoscopic surgery. Materials and Methods: We sent a questionnaire to institutes belonging to the Japanese Pediatric Endoscopic Surgery Group. Institutes were divided into two groups: institutes with (Group A) or without (Group B) ESSQS-qualified pediatric surgeons at any point in the last 10 years. Intraoperative complications (grade 3 and 4 under the Classification of Intraoperative Complications [CLASSIC] classification), postoperative complications (grade ≥IIIb under the Clavien/Dindo classification), and the number and rate of endoscopic procedures and complications of advanced and common procedures were compared between the two groups. This study is an exempt survey since no patient identifier has been collected. Results: We collected answers from 46 of 102 institutes (response rate: 45%) (Group A: 18 institutes, Group B: 28 institutes). Intra/postoperative complications were significantly more frequent in Group A than in Group B (P = .02 and P < .001, respectively). Endoscopic operations accounted for a larger proportion of advanced and common surgeries in Group A than in Group B, and the rate of postoperative complications of advanced procedures was significantly higher in Group A than in Group B (P = .012). Conclusion: While endoscopic surgery was performed more frequently in Group A than in Group B, the incidence of intra/postoperative serious complications was significantly higher in Group A. The current Japanese ESSQS was unable to markedly reduce the rate of serious complications.

Abstract
Background: Undescended testis (UDT) is one of the most common congenital genital malformations in boys. However, orchidopexy carries a risk of injuring the testicular vessels and vas deferens. We therefore developed a novel approach to manage palpable UDT. Materials and Methods: We analyzed the medical records of patients who underwent orchidopexy at our institute between January 2017 and April 2020. This study was approved by the Institutional Review Board of our hospital. The age, body weight, laterality, testicular position, length of operation, and complications were investigated. The patients were classified into two groups depending on the surgery received: laparoscopy-assisted transscrotal orchidopexy (LATO) or conventional inguinal orchidopexy (CO). In brief, LATO involves preceding laparoscopic closure of the patent processus vaginalis (PPV) followed by transscrotal orchidopexy. Dissection of the PPV from the testicular vessels and vas deferens was minimized through this procedure. The chi-squared test and t-test were used to analyze the significance of the data. Results: Among a total of 49 patients, 24 (33 testes) underwent LATO, and 25 (30 testes) underwent CO. There was no significant difference in patients' age, body weight, or laterality. The length of operation was similar between the groups in both unilateral and bilateral cases. The contralateral PPV was confirmed in 80% of unilateral cases of LATO (12/15). No complications, including testicular atrophy and postoperative ascent, were noted in either group. Conclusions: There were no significant differences between the groups in the surgical results. However, the confirmation and ligation of the PPV were easier in LATO, and peeling of the testicular vessels and vas deferens was minimized. LATO may be safe and effective for managing palpable UDT.

Abstract
Background Diaphragmatic hernia is a rare complication of ventricular assist device (VAD), mainly developing after explantation of the device. We herein report a case of diaphragmatic hernia that developed following the implantation of VAD. Case presentation A 4-month-old girl with a diagnosis of dilated cardiomyopathy underwent VAD implantation for a bridge to heart transplantation. Three months later, intermittent vomiting developed, and left-sided diaphragmatic hernia was confirmed on plain X-ray and computed tomography. Without any findings of ischemia, we performed elective thoracoscopic repair of the diaphragmatic hernia. In the right decubitus position, thoracoscopy revealed the small intestine to be herniated into the left thorax. After reduction of the herniated intestine, the defect of the diaphragm (3 × 2 cm in size) was directly closed with interrupted non-absorbable sutures. Her postoperative course was uneventful. Conclusion Thoracoscopic repair of diaphragmatic hernia associated with VAD implantation may be a safe approach.

Abstract
OBJECTIVES Mycophenolate mofetil (MMF) is mainly used in conjunction with calcineurin inhibitors as an additional immunosuppressive for renal sparing after liver transplantation. However, few reports about MMF use in infants after living donor liver transplantation (LDLT) are available. The purpose of this study was to examine the efficacy and safety of MMF in infants. METHODS This study enrolled infants younger than 1 year of age who received LDLT at our institution. Patients received oral MMF twice daily. The initial dose was 40 to 50 mg/kg/d, which was increased to a target mycophenolic acid (MPA) trough level of 2 mg/L. Body weight, height, MMF dose, MPA trough level, acute cellular rejection (ACR) episodes, pathologic findings, and adverse effects were analyzed. Allograft fibrosis was graded using the Meta-analysis of Histological Data in Viral Hepatitis score. RESULTS Patients received MMF for refractory ACR (n = 2), fulminant hepatitis (n = 2), and pre-existing antibodies (n = 1). Original diseases were biliary atresia (n = 3) and fulminant hepatitis (n = 2). Mean age at transplant was 8 months (range 3-10 months). The last available mean trough level was 2.7 mg/L. The mean dose was 66 mg/kg/d or 1429 mg/m2/d at the time of the last available through level. The regression line for MMF dose and MPA trough level was y = 1.8 × 10-3x. The correlation coefficient was 0.65. All allografts showed F1 to F2 fibrosis. Two patients discontinued MMF because of infection and bone marrow suppression, respectively. Two patients converted to everolimus. One patient continued on MMF. CONCLUSIONS After LDLT, infants require a higher MMF dose than older patients based on trough levels, but allograft fibrosis can progress.

Abstract
INTRODUCTION Serum beta-D-glucan (BDG) levels may increase with anti-adhesion barrier film (ABF) use during pediatric living donor liver transplantation (LDLT). It may affect detection of fungal infections after LDLT. We evaluate BDG levels after pediatric LDLT. METHODS Pediatric patients who received an ABF during LDLT were included. Patients who may have had fungal infections prior to LDLT were excluded. One sheet of ABF was placed in the peritoneum during abdominal closure. Serum BDG levels before transplantation and on postoperative days (PODs) 1, 4, 7, 14, 21, and 28 and peritoneal fluid BDG levels on PODs 1 and 7 were measured. RESULTS Sixteen patients received an ABF during LDLT. Median age at transplant was 1.9 years (range, 6-11 years). Median body weight was 12.6 kg (range, 6.8-39 kg). Indications for LDLT were biliary atresia (n = 10) and other (n = 5). Prior to transplantation, the mean serum BDG level was 3.8 pg/mL. Mean Serum BDG levels were 18.1, 38.3, 5.3, 3.8, 3.3, and 3.3 pg/mL on PODs 1, 4, 7, 14, 21, and 28, respectively. Mean peritoneal fluid BDG levels were 485.9 and 240.4 pg/mL on PODs 1 and 7, respectively. No clinical fungal infections were observed. CONCLUSIONS BDG levels were high in serum and peritoneal fluid after pediatric LDLT. Serum BDG levels normalized after POD 7. Careful interpretation of BDG levels until POD 7 is needed when an ABF has been used.

Abstract
PURPOSE Everolimus (EVR) is a derivative of sirolimus with a similar mechanism of action. The safety and efficacy of EVR after pediatric living donor liver transplantation (LDLT) are currently unknown. The purpose of this study was to examine the safety and efficacy of EVR as rescue therapy after pediatric LDLT. METHODS This study included patients younger than 19 years of age who received EVR after LDLT at our institution. EVR was administered as rescue treatment in addition to tacrolimus. In 21 patients, EVR dose, trough level, outcomes, and adverse effects were assessed. RESULTS Original diseases of patients consisted of biliary atresia (n = 11), Alagille syndrome (n = 3), fulminant hepatitis (n = 3), hepatoblastoma (n = 2), and other (n = 2). Mean age at transplant was 2.0 years (range 0.6-6.2 years). Mean age at initial EVR administration was 8.0 years (range 0.9-18.9 years). Indications for EVR use were graft fibrosis (n = 8), refractory acute cellular rejection (n = 5), renal sparing (n = 4), hepatoblastoma (n = 2), and chronic rejection (CR) (n = 2). Mean duration of administration was 17.1 months (range 2.1-60.4 months). Mean dose was 0.5 mg/m2 twice daily. Mean EVR trough level was 2.5 ng/mL (range 1.5-5.0 ng/mL). Liver function improved and fibrosis did not progress in all patients with CR. However, 14 patients (67%) experienced adverse effects that required EVR dose reduction or discontinuation. CONCLUSION EVR is tolerable for pediatric patients after LDLT with dose adjustment. EVR had a certain effect to relieve progression on CR. Further follow-up is required.

Abstract
OBJECTIVES Valganciclovir (VGCV) is used as prophylaxis against cytomegalovirus (CMV) infection after pediatric living donor liver transplantation (LDLT). The purpose of this study was to examine the efficacy of 1 year of preemptive VGCV administration compared with a shorter administration after pediatric LDLT. METHODS VGCV was administered to 56 children who underwent LDLT. CMV and Epstein-Barr virus (EBV) antibody status, pp65 antigenemia, and other laboratory data were assessed at 1 year after LDLT. Patients were divided into the 1-year group (n = 32) (patients who had 1 year of VGCV administration) and the <1-year group (n = 24) (patients who had less than 1 year of VGCV administration). RESULTS Study participants consisted of 34 females and 22 males, with a mean age of 4.2 years at transplant. Regarding pretransplant donor (D)/recipient (R) CMV antibody status, 13 were D positive (+)/R negative (-), 27 were D+/R+, 8 were D-/R+, and 8 were D-/R-. For EBV, 22 were D+/R+, 32 were D+/R-, and 2 were D-/R-. In the 1-year group, only 2 patients (6.5%) developed CMV infection, whereas 8 patients (33.3%) developed CMV infection in the <1-year group. The CMV pp65 antigenemia assay was positive in 2 patients. CMV IgM was positive in 7 patients. One year of preemptive VGCV administration was associated with a lower incidence of CMV infection (P = .008), but not EBV infection. No adverse effects were observed. CONCLUSIONS One year of preemptive VGCV administration after LDLT is safe and suppresses CMV infection. It was useful after pediatric LDLT.

Abstract
INTRODUCTION This study aimed to compare the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) and conventional open repair (OR) for inguinal hernia in infants younger than 6 months. METHODS The medical records of 202 patients who had undergone LPEC or OR at an age younger than 6 months between 2010 and 2016 were reviewed. Patient characteristics and surgical outcomes were compared between LPEC and OR. RESULTS In total, there were 120 LPEC (76 males, 44 females) and 83 OR (76 males, 7 females) cases. There were no differences in median age, median bodyweight, and presence of incarceration between the two groups (LPEC group: 3 months (range, 0-5 months), 5.7 kg (range, 2.3-9.6 kg), and 13.3%; OR group: 3 months (range, 1-5 months), 5.5 kg (range, 2.1-9.0 kg), and 12.0%). LPEC was completed in all cases without any intraoperative complications or open conversions. In the LPEC group, 60.0% of unilateral hernia patients had a contralateral patent processus vaginalis and underwent prophylactic closure. The incidence of metachronous contralateral hernia was significantly lower in the LPEC group than in the OR group (0% vs 10.0%, P < 0.01). Operative time was significantly shorter during LPEC than during OR (P < 0.01) for male patients. The recurrence rate was lower in the LPEC group (0.83%) than in the OR group (2.4%), but the difference was not significant. CONCLUSION The present data indicate that LPEC is comparable to OR in terms of safety and efficacy in infants younger than 6 months. Moreover, among the LPEC group, there were fewer incidences of metachronous contralateral hernia, and the procedure had a shorter operative time.

Abstract
PURPOSE Living-donor liver transplantations (LDLTs) with maternal grafts can be more successful than those with paternal grafts because of their tolerance to non-inherited maternal antigens. We reviewed LDLT patients to investigate the relationship between acute rejection and donor sex. METHODS LDLT patients between January 2010 and November 2015 were enrolled. ACR was defined by a rejection activity index of > 3. RESULTS Forty-six patients (22 males and 24 females), of whom 28 had biliary atresia, were enrolled. The median age of the patients was 2.8 years and the donor types were maternal (n = 25) and paternal (n = 21). Acute cellular rejection (ACR) was observed in 22 patients. Twelve (48%) of the 25 patients in the maternal group had at least one episode of rejection compared with 10 (48%) of the 21 in the paternal group. Among the patients with ACR, the first rejection in the maternal group occurred significantly earlier than that in the paternal group (p < 0.01). In the multivariable analysis, the only variable significantly related to the first rejection day after LDLT was donor sex (male) (p < 0.005). CONCLUSION Our results showed that maternal grafts had an effect on causing earlier ACR in LDLT.

Abstract
PURPOSE Ghrelin was recently reported to promote recovery from hepatic injury. We hypothesized that it could also be associated with clinical recovery of the transplanted liver from ischemia and reperfusion injury. Our aims were to investigate perioperative ghrelin changes following pediatric living donor liver transplantation (LDLT) and to analyze the association of these changes with postoperative hepatic function. METHODS We measured plasma acyl ghrelin (AG) concentrations before surgery, at the end of surgery and on postoperative days (PODs) 1, 3 and 7 in 12 children who underwent LDLTs, and, as controls, pre- and post-operatively and on POD1 in 7 children who underwent benign abdominal mass resection. The correlations between the participants' ghrelin profiles and hepatic function-related data were evaluated. RESULTS AG levels significantly declined to 15.6% of preoperative levels after LDLT and almost returned to baseline on POD3. Post-operative AG levels were significantly reduced to a greater extent following LDLT than benign abdominal mass resection. AG levels on POD1 inversely correlated with aspartate aminotransferase levels and cold/total ischemia time (P < 0.05). CONCLUSION These results suggest that reduced AG levels on POD1 may reflect the degree of damage to the transplanted liver due to ischemia and reperfusion injury.

Abstract
Pediatric living donor liver transplantation (LDLT) in patients with advanced portopulmonary hypertension (PoPH) is associated with poor prognoses. Recently, novel oral medications, including endothelin receptor antagonists (ERAs), phosphodiesterase 5 (PDE5) inhibitors, and oral prostacyclin (PGI2) have been used to treat PoPH. Pediatric patients with PoPH who underwent LDLT from 2006 to 2016 were enrolled. Oral pulmonary hypertension (PH) medication was administered to control pulmonary arterial pressure (PAP). Four patients had PoPH. Their ages ranged from 6 to 16 years, and their original diseases were biliary atresia (n = 2), portal vein obstruction (n = 1), and intrahepatic portal systemic shunt (n = 1). For preoperative management, 2 patients received continuous intravenous PGI2 and 2 oral medications (an ERA alone or an ERA and a PDE5 inhibitor), and 2 received only oral drugs (an ERA and a PDE5 inhibitor). One patient managed only with intravenous PGI2 died. In the remaining 3 cases, intravenous PGI2 or NO was discontinued before the end of the first postoperative week. Postoperative medications were oral PGI2 alone (n = 1), an ERA alone (n = 1), or the combination of an ERA and a PDE5 inhibitor (n = 1). An ERA was the first-line therapy, and a PDE5 inhibitor was added if there was no effect. New oral PH medications were effective and safe for use in pediatric patients following LDLT. In particular, these new oral drugs prevent the need for central catheter access to infuse PGI2.

Abstract
PURPOSE The Mac-2-binding protein glycosylation-modified isomer (M2BPGi) is a new marker for progression of hepatic fibrosis. We examined the relationship between serum M2BPGi levels and liver histological findings in patients with biliary atresia (BA) who were not transplant candidates. METHODS Patients with BA who were not transplant candidates with good liver function were included. We examined M2BPGi levels and histological findings in relation to other laboratory markers of liver fibrosis, including aspartate aminotransferase (AST) to platelet ratio index, fibrosis-4 index, and type IV collagen 7s domain. Liver fibrosis was evaluated based on the METVIR score. RESULTS 37 patients were included. The median age was 18 years (range 3-38 years). M2BPGi values ranged from 0.3 to 6.9 cutoff index (COI) (median 1.6). The degree of liver fibrosis varied with M2BPGi level. For predicting cirrhosis (F4) and advanced liver fibrosis (≥ F3), M2BPGi had higher areas under the curve (AUCs; 0.93, respectively) with cutoff COIs of 1.84 and 1.67, respectively, than for the four conventional markers for fibrosis. CONCLUSION M2BPGi is a novel marker for liver fibrosis in patients with BA. It is especially useful for following patients with BA with a native liver and supporting liver biopsy interpretation findings.

Abstract
AIM Thoracoscopic repair (TR) of esophageal atresia with tracheoesophageal fistula (EA/TEF) remains a considerable challenge, even for the most experienced pediatric surgeons. The aim of this study is to report the outcomes of our experience with TR of EA/TEF and to determine the learning curve for this procedure. METHODS Eleven consecutive cases that had undergone TR of EA/TEF at our institutes were included in this study. The medical charts were reviewed retrospectively. To determine the learning curve for TR of EA/TEF, a logarithmic curve-fitting analysis was performed. The data were expressed as medians with ranges. RESULTS The median age and birth weight were 1 day (range, 1-3 days) and 2.8 kg (range, 2.5-3.7 kg), respectively. TR was completed in all cases without any complications. The median operative time was 230 min (range, 164-383 min). There were no cases of anastomotic leakage. One patient with a long gap required repeated balloon dilatation for refractory anastomotic stricture. No mortality or recurrence of tracheoesophageal fistula occurred. The operative time was significantly longer in patients with a long gap (>20 mm) than in those with a shorter gap. Once the three cases with a long gap had been excluded, the operative time decreased as the number of treated cases increased. The relationship between the operative time and case number fit a logarithmic function curve well (operative time in minutes = 300 - 62 × log (case number), R2 = 0.8359, P = 0.0015). CONCLUSIONS Our results suggest that TR of EA/TEF is a safe procedure. It has a considerable learning curve, but requires advanced endoscopic surgical skills.

Abstract
PURPOSE Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PoPH) are extrahepatic complications of biliary atresia (BA). Their detection is sometimes delayed, which may result in missed opportunities for liver transplantation. The aim of this study was to determine the onset ages of HPS and PoPH in BA patients. METHODS BA patients followed at our institution were identified. Patients visited our clinic for routine blood work, as well as regular electrocardiography, chest X-rays, and arterial blood gas tests. Lung perfusion scintigraphy and cardiac ultrasound were performed to diagnose HPS. Cardiac catheterization was conducted to diagnose PoPH. RESULTS The study population consisted of 88 BA patients. The median follow-up duration was 11.6 years (range 0.8-26.0 years). Six patients (6.8%) developed HPS and three patients (3.4%) developed PoPH. The median age of onset of HPS was significantly younger than that of PoPH (HPS: 4 years, PoPH: 15 years, P < 0.019). Two patients (66%) with PoPH died, while all patients with HPS survivied. CONCLUSION The onset of HPS was significantly earlier than that of PoPH. The mortality rate was high in patients with PoPH. Teenagers with BA should receive routine cardiac echocardiograms to detect PH in its early stages.

Abstract
Congenital esophageal stenosis (CES) is rare and usually manifests in infants as dysphagia, failure to thrive, and food impaction. Dilatation is considered to be the first-line therapy for CES, but the incidence of complications (perforation and mediastinitis) is relatively high. We report two cases of CES treated by thoracoscopic resection without prior dilatation. Both infants recovered without recurrent stenosis and were able to eat solid food soon after surgery. One had postoperative gastroesophageal reflux and eventually required fundoplication. Thoracoscopic resection could be a valid option for CES.

Abstract
PURPOSE To investigate the long-term morbidity of surgically treated esophageal atresia (EA) in adolescents and young adults and establish whether these long-term morbidities are affected by the type of EA. PATIENTS AND METHODS We reviewed the medical records, including backgrounds and associated conditions, of 69 long-term survivors of EA, aged >15 years. The long-term morbidities included neurodevelopmental abnormality, nutritional impairment (short height <-2SD, low BMI <18.5), subjective symptoms, and musculoskeletal deformities. Comparisons of the results were made between Gross A-type EA (n = 6) and Gross C-type EA (n = 63). RESULTS All patients underwent esophageal anastomosis without esophageal replacement. Cardiac anomalies and long gap were present in 26 and 18%, respectively. Esophageal dilatation, fundoplication, and aortopexy were performed in 40, 34, and 18%, respectively. The incidence of long gap and esophageal stenosis was higher in Gross A-type EA than in Gross C-type EA. The long-term morbidities included neurodevelopmental abnormality (13%), nutritional impairment (62%: as short height in 34% and as low BMI in 46%), subjective symptoms (14%), and musculoskeletal deformities (59%). There were no differences in the long-term morbidities between Gross A and Gross C. CONCLUSIONS The incidence of the long-term morbidities is high in adolescents and young adults, regardless of the type of EA. Early detection of morbidity is important to improve the long-term outcomes of EA.

Abstract
Purpose Intestinal perforation and necrotizing enterocolitis (NEC) are neonatal intestinal emergencies that are especially common in premature infants. While prompt surgical intervention, including stoma creation, is often required, the optimal surgical treatment has been controversial because of the substantial risks related to the stoma creation and management. The use of a tissue adhesive may have some advantages over the use of sutures when creating an intestinal stoma in extremely low birth weight (ELBW) infants. The purpose of this report was to present a novel approach for creating a stoma using a tissue adhesive in ELBW infants. Methods A total of eight ELBW infants that underwent laparotomy with the creation of intestinal stomas using cyanoacrylate adhesive at our institution between 2009 and 2014 were enrolled. The clinical parameters, including the length of the operation, intra- and postoperative complications and the outcomes were evaluated. Results The median body weight and gestational age at birth were 630 g and 24.3 weeks, respectively. The median age at referral was 11.5 days. The median length of the procedure was 58.5 min, including the inspection and resection of the intestine. All procedures were completed without any intraoperative complications. There were no postoperative complications associated with the stoma. Two patients died of the associated septic status. Conclusions Sutureless enterostomy using cyanoacrylate adhesive is a simple technique which has the potential to reduce the incidence of complications related to the intestinal stoma in ELBW infants.

Abstract
PURPOSE Necrotizing enterocolitis (NEC) is a devastating inflammatory disease of preterm infants that may depend on overexpression of toll-like receptor-4 (TLR4) in the immature intestine. Surfactant protein (SP)-D is a member of the collectin family and plays an important role in innate immunity, particularly in the airways. Although SP-D also exists in the intestines, little is known about its function. This study investigated whether SP-D can attenuate the inflammatory response of TLR4-overexpressing embryonal intestinal cells. METHODS All experimental procedures were performed using the human intestinal cell line INT407 originally derived from human embryonal intestines. Platelet-activating factor (PAF), reported to be elevated in NEC patients, was used to induce TLR4 overexpression in the human embryonal intestinal cell line INT407. TLR4 expression was measured using quantitative real-time PCR. Inflammatory responses to PAF (5 µM), the TLR4 agonist lipopolysaccharide (LPS, 100 ng/ml), PAF + LPS, and PAF + LPS following SP-D pretreatment (20 µg/ml) were assessed by enzyme-linked immunosorbent assay (ELISA) of interleukin-8 (IL-8) release (in pg/ml). RESULTS Expression of TLR4 mRNA (mean ± SD) was upregulated by PAF (369 % ± 28 %, p < 0.001). Stimulation with PAF + LPS resulted in higher IL-8 release (1959.3 ± 52.3) than control (141.2 ± 12.4), LPS (167.3 ± 65.8), or PAF (1527.2 ± 129.4) treatment (p < 0.05). Release in response to PAF + LPS (1590.1 ± 319.3) was attenuated by SP-D pretreatment (1161.6 ± 131.6; p < 0.05). CONCLUSION SP-D attenuates LPS-induced IL-8 production in TLR4-overexpressing intestinal cells, suggesting that SP-D may have a protective effect in the development of NEC in preterm infants.

Abstract
PURPOSE The aim of this study was to evaluate the long-term outcomes of four patients with tracheal agenesis who underwent airway and esophageal/alimentary reconstruction. MATERIALS AND METHODS We reviewed the medical records of four long-term survivors of tracheal agenesis and collected the following data: age, sex, type of tracheal agenesis, method of reconstruction, nutritional management, and physical and neurological development. RESULTS The patients consisted of three boys and one girl, who ranged in age from 77 to 109months. The severity of their condition was classified as Floyd's type I (n=2), II (n=1), or III (n=1). Mechanical respiratory support was not necessary in any of the cases. Esophageal/alimentary reconstruction was performed using the small intestine (n=2), a gastric tube (n=1), and the esophagus (n=1). The age at esophageal reconstruction ranged from 41 to 55months. All of the cases required enteral nutrition via gastrostomy. Three of the patients were able to swallow a small amount of liquid and one was able to take pureed food orally. The physical development of the subjects was moderately delayed-borderline in childhood. Neurological development was normal in two cases and slightly delayed in two cases. CONCLUSIONS None of the long-term survivors of tracheal agenesis required the use of an artificial respirator, and their development was close to normal. Future studies should aim to elucidate the optimal method for performing esophageal reconstruction to allow tracheal agenesis patients to achieve their full oral intake.

Abstract
BACKGROUND/PURPOSE Ovarian preservation is desirable in children with ovarian tumors. However, the diagnostic and treatment strategies are heterogeneous. The aim of this study was to investigate the management and preservation of ovarian tissue in order to identify the factors associated with ovarian preservation. METHODS Thirty-seven patients (41 ovaries) were surgically treated for ovarian tumors. Four cases were bilateral. The data on the patient symptoms at presentation, imaging, treatment, outcome, pathology, and status of ovarian preservation were retrospectively analyzed for each patient. RESULTS Histological examinations revealed 25 mature teratomas, 5 immature teratomas, 5 cystadenomas, 2 dysgerminomas, and other tumors. Ovarian torsion occurred in 16 ovaries (39%). Ovary-sparing surgery was performed in 22 ovaries (53.7%). Successful ovarian preservation was significantly associated with a smaller tumor size, benign pathology, and a lower degree of torsion (P<0.01). CONCLUSIONS Because the prognosis was favorable in most cases, the preservation of fertility and gonadal function should be a goal in the surgical treatment of ovarian tumors. We recommend ovary-sparing surgery as the first-line treatment for all pediatric ovarian tumors other than those that are preoperatively diagnosed as being malignant and those in which emergent surgical intervention is indicated owing to the suspicion of ovarian torsion.

Abstract
Chronic intussusception, defined as intussusception continuing over 14 days, is rare in children. We herein report a case of chronic ileocolic intussusception caused by the transmural infiltration of diffuse large B cell lymphoma in a 14-year-old boy. The patient had been suffering from anorexia and intermittent abdominal pain for 5 weeks, during which his body weight decreased by around 7 kg. Upon admission to our hospital, ultrasonography and enhanced computed tomography (CT) of the abdomen showed ileocolic intussusception. A retrospective examination of abdominal CT led us to suspect that the intussusception had initially appeared 5 weeks before admission, presumably coinciding with the beginning of the patient’s abdominal symptoms. Since hydrostatic reduction was unsuccessful, laparotomy was performed, which showed unreducible ileocolic intussusception with a marked edematous ileum and mesentery. Ileocecal resection without lymph node dissection was carried out, and a histological examination of the resected specimen revealed the transmural infiltration of diffuse large B-cell lymphoma of the terminal ileum. The patient’s postoperative course was uneventful, and adjuvant chemotherapy was administered. This case illustrates the diagnostic challenges of confirming ‘chronic’ intussusception in older children.

Abstract
PURPOSE Surfactant protein D (SP-D) is one of specific surfactant proteins constituting pulmonary surfactant. Recent studies have revealed that SP-D is detected in various non-pulmonary tissues and is involved in the host defense and immunomodulation. However, the relationship between SP-D and liver diseases has not yet been investigated. The aim of this study was to detect the immunolocalization of SP-D in the livers of infants with cholestatic liver disease. METHODS The expression of immunoreactive SP-D was assessed in infants with cholestasis, including biliary atresia (BA, n=7), neonatal hepatitis (NH, n=2), and paucity of the intrahepatic bile duct (PIBD, n=4). Immunoreactive SP-D was also assessed in six infants who died of non-liver disease as controls. Tissue samples were obtained at liver biopsy, or by post-mortem sampling. The tissue sections were incubated with anti-SP-D polyclonal antibodies and were counterstained with hematoxylin. RESULTS In the normal livers, SP-D was detected in the intrahepatic bile ducts, but was not detected in hepatocytes. In contrast, intense SP-D staining was noted in the hepatocytes from infants with BA, NH, and PIBD. Although SP-D was detected in the intrahepatic bile ducts in the infants with NH, negative or weak staining was seen in the intrahepatic bile ducts in infants with BA. CONCLUSION Our data showed that SP-D is present in the bile ducts of the normal infant liver, and it was found to accumulate in the hepatocytes of cholestatic livers. These results suggest that SP-D is produced in hepatocytes and is secreted into the bile ducts.

Abstract
BACKGROUND There are few reports of the laparoscopic findings of the internal inguinal ring (IIR) in patients with hydrocele. The purpose of this study was to assess the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) for hydrocele in comparison with that of open repair (OR) and compare the findings of the IIR between cases of hydrocele and inguinal hernia (IH). MATERIALS AND METHODS We analyzed 69 consecutive patients with hydrocele who underwent surgery at our institution between April 2009 and February 2014. The patients were divided into two groups (LPEC and OR) according to the procedure. Age, length of operation/anesthesia, and complications were compared. Concerning the findings of the IIR, we classified the features into three categories, as follows: Type 1, flat; Type 2, narrow patent processus vaginalis (PPV) with a peritoneal veil; and Type 3, widely opened PPV. We then compared these findings between the cases of hydrocele and IH treated with LPEC during the study period. RESULTS Among a total of 69 patients, 40 underwent LPEC, and 29 underwent OR. There were no significant differences in the length of operation/anesthesia and complications. No recurrences were observed in either group. The findings of the IIR were mostly classified as Type 2 (59.1%) among the cases of hydrocele and Type 3 (92%) among the cases of IH. CONCLUSIONS LPEC is a safe and effective procedure for treating hydrocele. The findings of the IIR differ between cases of hydrocele and IH.

Abstract
INTRODUCTION Laparoscopic procedures for inguinal hernias and hydroceles in children have become widespread in the past few decades. The purpose of this study was to perform a retrospective analysis of our experience in order to assess the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) and to compare the findings with those of conventional open repair (OR). SUBJECTS AND METHODS We analyzed the medical records of 488 patients who underwent LPEC or OR for inguinal hernia or hydrocele at our institute between April 2008 and December 2012. The indications for the operation, length of the operation, complications, day surgery, contralateral patent processus vaginalis, and incidence of metachronous contralateral hernia were investigated. The chi-squared test, unpaired t test, and Steel-Dwass test were used to analyze the significance of the data. RESULTS Among a total of 488 patients, 326 patients underwent LPEC (125 males and 201 females), and 162 underwent OR (140 males and 22 females). There was no significant difference in the incidence of recurrence (three in the LPEC and none in the OR group, P=.55) or in the success rates of day surgery (97.8% in LPEC versus 97.6% in OR). The incidence of metachronous contralateral hernias in the LPEC group was lower than that in the OR group (LPEC 0%; OR 2.2%, P=.03). Seventeen subjects with hydroceles were treated by LPEC without any complications. CONCLUSIONS LPEC is safe and effective for inguinal hernias and hydroceles in children, regardless of age, sex, and incarceration and could reduce the incidence of metachronous contralateral hernias.

Abstract
Midgut malrotation is an anomaly of intestinal rotation that occurs during fetal development and usually presents in the neonatal period. We present a rare case of malrotation in a 14-year-old patient who presented with cramping, generalized right abdominal pain, and vomiting for a duration of one day. A computed tomography abdominal scan and upper gastrointestinal contrast studies showed malrotation of the small bowel without volvulus. Laparoscopy revealed typical Ladd’s bands and a distended flabby third and fourth duodenal portion extrinsically obstructing the misplaced duodeno-jejunal junction. The Ladd procedure, including widening of the mesenteric base and appendectomy, was performed. Symptoms completely resolved in a half-year follow up period. Patients with midgut malrotation may present with vague abdominal pain, intestinal obstruction, or intestinal ischemia. The laparoscopic Ladd procedure is feasible and safe, and it appears to be as effective as the standard open Ladd procedure in the diagnosis and treatment of teenage or adult patients with intestinal malrotation.

Abstract
BACKGROUND/PURPOSE Percutaneous endoscopic gastrostomy (PEG) is a simplified catheter placement procedure for alimentation. Although the endoscopic approach to gastrostomy tube placement is a safe and well-tolerated procedure in most patients, the PEG procedure is difficult in elderly patients disabled since childhood who have severe scoliosis and malpositioning of the stomach. We describe a simple and effective laparoscopic-assisted PEG (LAPEG) technique that can be used for catheter placement in severely disabled patients. METHODS Thirteen severely disabled patients aged 14-57 years underwent gastrostomy tube placement with the LAPEG technique. After general anesthesia was achieved, an endoscope was placed into the stomach. Then, a 5-mm camera port was inserted at the umbilicus, and a 3-mm working port was inserted to identify and lift the optimal site for gastrostomy tube placement. After the 4-point fixation of the stomach, the 20-Fr gastrostomy tube was placed under endoscopic and laparoscopic observation. RESULTS All patients tolerated the procedure well, and there were no major complications. The procedure was successful, and all patients could feed via the tube. CONCLUSIONS Elderly disabled patients who have been bedridden since childhood often have severe scoliosis and malpositioning of the stomach. Our LAPEG procedure is effective, well tolerated, and safe for gastrostomy tube placement in such elderly patients.

Abstract
Tracheal agenesis is a rare and usually lethal congenital malformation of the forgut. Although some infants can be resuscitated with an intra-esophageal intubation temporarily, long-term airway management is difficult because of the collapsing airway. We report a long-term survivor with tracheal agenesis in whom a Gortex external esophageal stent using radial traction sutures was applied to prevent the esophagus from collapsing. The patient was discharged from our hospital without mechanical ventilation or oxygen inhalation at 10 months of age. Our procedure has a potential to establish a long-term steady airway in patients with tracheal agenesis. The detail of the procedure is presented and the related literature is reviewed.

Abstract
BACKGROUND/PURPOSE An accurate diagnosis is mandatory for surgery in newborns with Hirschsprung's disease (HD). Acetylcholinesterase staining of rectal suction biopsy specimens is widely performed in the diagnosis of HD, but results are sometimes incorrect or atypical in newborns. We report the usefulness of our method of anorectal manometry using a specially designed sleeve microassembly for the diagnosis of neonatal HD. METHODS Anorectal manometry was conducted without sedation in 41 newborns, aged 2 to 30 days (19 newborns were within the first week of life), with abdominal distension. A silastic assembly with a 2-cm-long sleeve sensor and 5 side holes arrayed along the sleeve was designed to reduce the effects of displacement of pressure sensors relative to the anal sphincter. Rectoanal inhibitory reflex (RAIR) was examined with rectal balloon distension. RESULTS Thirty-two subjects who showed falls of anal sphincter pressure fulfilling the criteria for RAIR were diagnosed to be without HD. Nine patients without an appropriate RAIR were subsequently confirmed to have HD based on operative pathologic findings. Parameters of anal sphincter function did not differ significantly between the subjects with and without RAIR. CONCLUSIONS An anorectal sleeve micromanometric technique is useful in the diagnostic workup of newborns suspected of having HD.

Abstract
BACKGROUND/PURPOSE The objective of this study is to investigate the characteristics of esophageal motor activity responsible for the development of gastroesophageal reflux (GER) in patients with esophageal atresia (EA). METHODS The subjects consisted of 29 patients with EA (1 month to 19 years). Computerized esophageal manometry was conducted to investigate esophageal contractions at swallow. A topographic esophageal manometric analysis was conducted in each subject, providing 3-dimensional displays to reveal the pressure continuum representing esophageal contractions. RESULTS Significant contractions in the middle esophagus just below the anastomosis were absent in all subjects. Contractions in the distal esophagus were conspicuously absent in 17 subjects. Of these 17, 6 had already undergone fundoplication, and 9 had symptomatic GER requiring fundoplication subsequent to this study. The remaining 12 patients had contractions in the distal esophagus and did not require medical/surgical intervention. A lack of distal esophageal contractions was significantly correlated with the development of GER (P < .001). There was a significant difference in esophageal acid exposure between the 2 groups (median, 38% vs 4%, P < .001). CONCLUSION Lack of distal esophageal contractions indicating an impaired clearing capacity is considered a potential key determinant of GER in patients with EA.
