Esophageal atresia (EA) with proximal tracheoesophageal fistula (TEF; gross type B) is a rare defect. Although most patients have long-gap EA, there are still no established surgical guidelines. A premature male infant with symmetric intrauterine growth retardation (birth weight, 1,616 g) was born at 35 weeks and 5 days of gestation. The initial diagnosis was pure EA (gross type A) based on failure to pass an orogastric tube and the absence of stomach gas. A "feed and grow" approach was implemented, with gastrostomy performed on postnatal day 2. A fistula was detected during bronchoscopy for recurrent pneumonia; thus, we confirmed type B EA and performed TEF excision and cervical end esophagostomy. As the infant's stomach volume was insufficient for bolus feeding after reaching a body weight of 2.5 kg, continuous tube feeding was provided through a gastrojejunal tube. On the basis of these findings, esophageal reconstruction with gastric pull-up was performed on postnatal day 141 (infant weight, 4.7 kg), and he was discharged 21 days postoperatively. At 12 months after birth, there was no catch-up growth; however, he is currently receiving a baby food diet without any complications. In patients with EA, bronchoscopy is useful for confirming TEF, whereas for those with long-gap EA with a small stomach volume, esophageal reconstruction with gastric pull-up after continuous feeding through a gastrojejunal tube is worth considering.

Tracheoesophageal fistula without esophageal atresia (H-type TEF) is a congenital anomaly that is characterized by a fistula between the posterior wall of the trachea and the anterior wall of the esophagus, not accompanied by esophageal atresia. The purpose of this study is to investigate the clinical characteristics, diagnostic time, the side of cervical approach and short term result after surgery by searching medical records of patients treated for H-type TEF. The search was done at University of Ulsan, Department of Pediatric Surgery of Asan Medical Center, and the total number of patients from May 1989 to December 2010 was 9 with M:F ratio of 1:2. The median gestational age was $39^{+6}$ ($32^{+6}{\sim}41^{+0}$) wks. Seven out of nine patients were born at term and the other two were born premature. The clinical presentation was aspiration pneumonia, difficulty in feeding, chronic cough, vomiting, abdominal distension and growth retardation. The symptoms presented right after birth. The diagnosis was made with esophagography and the median time of diagnosis was 52 days of life. The majority of surgical corrections were performed within two weeks of diagnosis (median; 15d, range; 1d - 6m). Six patients had associated anomalies, and cardiac anomalies were most common. The cervical approach was utilized in all cases (right 2, left 7). Transient vocal cord palsy and minor esophageal leakage complicated two cases. Although the diagnosis of H-type TEF was difficult and often delayed, we had a good short term result. The left cervical approach was preferred.

Purpose: To determine the clinical manifestations and outcomes of patients with tracheoesophageal fistula (TEF) and esophageal atresia (EA) born at a single neonatal intensive care unit. Methods: A retrospective analysis was conducted for 97 patients with confirmed TEF and EA who were admitted to the neonatal intensive care unit between 1990 and 2007. Results: The rate of prenatal diagnosis was 12%. The average gestational age and birth weight were $37^{+2}$ weeks and $2.5{\pm}0.7kg$, respectively. Thirty-one infants were born prematurely (32%). Type C was the most common. The mean gap between the proximal and distal esophagus was 2 cm. Esophago-esophagostomy was performed in 72 patients at a mean age of 4 days after birth; gastrostomy or duodenostomy were performed in 8 patients. Forty patients exhibited vertebral, anorectal, cardiac, tracheoesophageal, renal, limb (VACTERL) association with at least 2 combined anomalies, and cardiac anomaly was the most common. The most common post-operative complications were esophageal stricture followed by gastroesophageal reflux. Balloon dilatation was performed for 1.3 times in 26 patients at a mean age of 3 months. The mortality and morbidity rates were 24% and 67%, respectively, and the most common cause of death was sepsis. The weight of approximately 40% patients was below the 10th percentile at 2 years of age. Conclusion: Mortality and morbidity rates of patients with TEF and EA are high as compared to those of infants with other neonatal surgical diseases. Further efforts must be taken to reduce mortality and morbidity and improve growth retardation.

Isolated(H-type) tracheoesophageal fistula without esophageal atresia occurs in approximately 4% of esophageal anomalies, and represents the least form of abnormal laryngotracheo-esophageal communication. Its symptoms such as coughing and choking The during the feeding, abdominal distension and recurrent pneumonitis usually start from birth. Diagnosis is made between 4 days to 4 years using the contrast esophagography and/or tracheoscopy. In case of diagnostic delay the postoperative mortality is not negligible and the most common cause of mortality is respitatory problems(infection, respiratory distress). So early diagnosis is essential in the newborn period with high index of suspicion. We report a case of H-type TEF in which operative repair was successful with references to recent literature.

This study reviews 14 years' experience treating esophageal atresia with special emphasis on the clinical profile and outcome. From May 1989 to February 2003, 65 cases of esophageal atresia (EA) were treated at Asan Medical Center. Boys outnumbered girls 2.4 to 1. Prematutity and low birth weight were 27.7% and 38.5%. Esophageal atresia with distal tracheoesophageal fistula (TEF) was the most common type (87.7%), followed by pure EA and H type fistula. Forty-six patients (70.8%) had one or more associated anomalies, cardiac malformations were the most common. Duodenal atresia was found in 7 cases. There were 6 patients (9.2 %) with VATER cluster. VACTERL cluster was present in 18 patients (27.7%), one of who fulfilled the complete syndrome. Waterston group A, B and C made up 21.5%, 40.0% and 38.5% of the total group. Surgical treatment was attempted in 63 patients and deferred in 2 who had severe associated malformations. For EA with distal TEF, primary esophago esophagostomy was carried out in 51 cases, and division of TEF and gastrostomy in 4 cases and no operation in 2 cases. For pure EA, colonic graft was done in 2 after gastrostomy and esophagostomy, and esophago esophagostomy was performed in 2 after gastrostomy. Two patients with pure EA are waiting for the second operation after gastrostomy. Division of TEF was carried out in 2 cases with H type TEF. The overall survival rate was 76.9%, and survival by Waterston classification was 100% in group A, 80.8% in B and 60.0% in C. Thorough workup for associated anomalies, interdepartmental approach and more careful surgical decision and technique are required to improve the outcome of EA.

Children who underwent reparative operations for esophageal atresia (EA) with or without tracheoesophageal fistula (TEF), are confronted with many gastrointestinal or respiratory problems, especially during the early years of life. We reviewed the medical records of 50 patients who underwent repairs of EA with or without TEF at the Division of Pediatric Surgery, Samsung Medical Center, from December 1994 to December 2005. Current status of children was accessed by telephone-interview, but only 27 of them were accessible. Of 50 patients, 3 patients (6 %) were type A, 45 patients (90 %) were type C, and 2 patients (4 %) were type E. The mean interval between primary operation and interview was 5.5 years. The incidences of growth retardation (<10 percentile of height/weight) were 39 % and 21 % during the first 5 years after repairs, respectively. The incidences of dysphagia or gastroesophageal reflux and recurrent respiratory infections were 33 % and 39 %, respectively. However, these problems were likely to improve as the children grew. The incidences of growth retardations (<10 percentile of height/weight) were 11 % and 11 % for the children more than five years postoperative. The incidences of dysphagia or gastroesophageal reflux and recurrent respiratory infections were 22 % and 22 %, respectively. Children with EA with or without TEF are faced with many obstacles. Close observation and adequate treatment for delayed postoperative complications are necessary to improve the quality of life for these children.

There is significant morbidity and mortality associated with the combination of esophageal atresia (EA) and duodenal atresia (DA). Nevertheless, the management protocol for the combined anomalies is not well defined. The aim of this study is to review our experience with the combined anomalies of EA and DA. From May 1989 to August 2006, seven neonates were diagnosed as EA with DA at Asan Medical Center. In all cases, the type of EA was proximal EA and distal tracheoesophageal fistula (TEF). The diagnosis of DA was made in theprenatal period in 1, at birth in 4, 4 days after birth in 1 (2 days after EA repair) and at postmortem autopsy in 1. Except the one case where DA was missed initially, primary simultaneous repair was attempted. DA repair with gastrostomy followed by EA repair in 2, EA repair followed by DA repair without gastrostomy in 2, and TEF ligation followed by DA repair with gastrostomy in 1. There were two deaths. One baby had a large posterolateral diaphragmatic hernia, and operative repair was not attempted. The other infant who had a TEF ligation and DA repair with gastrostomy expired from cardiac failure due to a large patent ductus arteriosus. Simultaneous repair of EA and DA appears to be an acceptable management approach for the combined anomalies, but more experience would be required for the selection of the primary repair of both anomalies.

Purpose: Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a congenital anomaly that can cause frequent digestive and nutritional problems, even after repair. The most common complication is anastomotic stricture, for which reoperation or balloon dilatation is performed. This study aimed to evaluate the postoperative complications of EA and the role of endoscopic balloon dilatation (EBD) in cases of anastomotic stricture. Methods: We retrospectively analyzed patients diagnosed with EA with or without TEF between January 2000 and February 2021. Patients' baseline characteristics, associated anomalies, and postoperative complications were reviewed. Results: Among 26 patients, 14 (53.8%) were male, 12 (46.2%) had coexisting anomalies, and the median follow-up was 6.1 years (range, 1.2-15.7 years). In univariate analysis, prematurity, low birth weight, and long-gap EA were associated with postoperative complications in 12 (46.2%) patients. Among the 10 (38.5%) patients with anastomotic stricture, nine (90.0%) required EBD. Regarding the first EBD, it was performed at a median of 3.3 months (range, 1.2-7.6 months) post-repair, while the average patient weight was 4.6 kg. The mean diameter ranged from 3.3 to 9.1 mm without major complications. In univariate analysis, long-gap EA alone was significantly associated with EBD. Conclusion: Approximately half of the patients experienced complications after EA repair. In particular, patients with a long-gap EA had a significantly increased risk of complications, such as anastomotic strictures. EBD can be safely used, even in infants.

Parenteral nutrition has been an essential part of postoperative care of neonates requiring major surgery who are unable to tolerate enteral feeding for long periods during the postoperative period. However, TPN via central venous catheters(central TPN), used in increasing trend, still presents significant morbidity. To find out whether TPN via peripheral veins(peripheral TPN) could be used as a viable alternative for postoperative parenteral nutrition in neonates, a clinical study was carried out by a retrospective analysis of 53 neonates subjected to peripheral TPN for more than 7 days after surgery. Operations consisted of procedures for esophageal atresia with tracheoesophageal fistula, gastroschisis and omphalocele. Surgery was performed at the Division of Pediatric Surgery, Department of Surgery, Hanyang University Hospitall, from 1983 to 1994. The mean total duration of TPN was 13.3 days (range; 7-58 days), the average daily total fluid intake was 117.6 ml/kg during TPN and 158.6 ml/kg during subsequent oral feeding. The average daily total calorie intake was 57.7 kcal/kg during full strength TPN and 101.3 kcal/kg during subsequent oral feeding. The mean urine output was maintained at 3.5 ml/kg/ hour during TPN and at 3.6 ml/kg/hour during subsequent oral feeding. The increment of body weight observed during TPN was 132 g in TEF, 53 g in gastroschisis and 3 g in omphalocele patients, while loss of body weight was not observed. The mortality rate was 5.7 %(3/53) and was related to the underlying congenital anomalies, not the TPN. The most common complication of peripheral TPN observed was laboratory findings suggestive of liver dysfunction in 23 cases(43.4 %) with no significant clinical symptom or signs in any case, transient pulmonary edema in one case, and generalized edema in one case. None of the major complications usually expected associated with central TPN were observed. The result of this study suggest that peripheral TPN can be used for adeguate postoperative nutritional support in neonates requiring 2 to 3 weeks of TPN.
