From 1979 to 2006, fifty eight patients with esophageal atresia were treated by one pediatric surgeon at Hanyang University Hospital. We analyzed the clinical findings and outcome of these 58 patients. There were 30 males and 28 females. Their mean birth weight was 2,960 +/- 400 g (1,170~4,020 g). The most common type of anomaly was Gross type C (49 patients; 84.5 %). There was no type B. Fifty-two patients underwent definitive surgery. Postoperative complications were as follows: anastomotic leakage in 17 patients (32.7 %), anastomotic site stricture in 15 (28.8 %), gastroesophageal reflux in 10 (19.2 %) and recurrent TEF in 1 (1.9 %). A total of 152 associated anomalies were detected from 48 patients (82.2 %). The cardiovascular system was the most commonly affected (30 patients with 46 anomalies). The VACTERL association was present in 14 patients (24.1 %). Operative mortality was 17.3 % including self-discharge patients after operation.

Contralateral exploration in children with unilateral inguinal hernia is controversial. This study was done to identify risk factors for the development of contralateral inguinal hernia in patients with unilateral inguinal hernia. The clinical experience of 4,206 inguinal hernias repaired by one pediatric surgeon on 3,358 children at HanYang University Hospital from September 1979 to December 2002 was analyzed. 1,868 (55.6%) hernias occurred on right side, 1,190 (35.4%) on left side, and 300 (8.9%) were bilateral. 2,702 children were boys and 656 were girls (M:F=4.1:1). 170 children of 3,058 children with unilateral hernias (5.6%) developed contralateral inguinal hernia at 1 day to 95 months after herniotomy. 146 children were boys and 24 were girls (M:F=6.1:1). The patients who had had herniotomy before 1 year of age developed contralateral hernia in 17.4%, compared with 5.6% overall average. The earlier the first herniotomy was performed, the more frequently contralateral hernia developed. The occurrence of contralateral inguinal hernia was more frequent in boys (146 of 2,460, 5.9%) than girls (24 of 598, 4.0%) and more frequent after left herniotomy (80 of 1,190, 6.7%) than after right herniotomy (90 of 1,868, 4.8%), but statistically not significant. 52.9% of contralateral inguinal hernia developed within 1 year after hernia repair, and 87.6% developed within 3 years. Routine exploration on contralateral side in children is not necessary.

Conventional treatment of Hirschsprung's disease consists of initial colostomy followed by pull-through operation. But, the treatment of Hirschsprung's disease has been changed along with the development of new surgical technique. Since 1995, endo-GIA has been available at our hospital and one stage Duhamel operation has been performed for neonatal Hirschsprung's disease. Between May 1995 and April 2006, 26 neonates have been treated with one stage pull-through operation by one pediatric surgeon at HanYang University Hospital. The sex ratio was 4.2:1 with male predominance. Clinical findings included abdominal distension (96.2 %), vomiting (50.0 %), delayed passage of meconium (46.2 %), constipation (23.1 %), and enterocolitis (15.4 %). Twenty two cases (84.6 %) were short-segment and 4 cases (15.4 %) were long-segment disease, of which 2 cases were total colon aganglionosis. One of the two patients with total colonic aganglionosis had double transition zones - distal ileum and hepatic flexure of the colon. The average age at operation was 14.56 +/- 8.77 days and the average weight at operation was 3.26+/-0.66 kg. Primary Duhamel operations were performed in 25 patients and Soave-Boley operations was performed in one patient. The endo-GIA 35 (Ethicon, USA) was used from 1995 until 1997, and after that endo-GIA 60 (USSC, USA) was used. The average Duhamel operation time was 88.57 +/- 22.80 minutes. Wound abscess (n = 2) and septum formation (n =1) occurred after Duhamel operation. Bowel function was normalized in 59 % within 3 months and in 95% within 1 year after operation. There was no mortality after one stage pull-through operation in neonate.

Intestinal malrotation is usually asymptomatic and most often is found during abdominal exploration for other surgical diseases. However, a serious complication of intestinal malrotation, midgut volvulus is a true surgical emergency of childhood. The clinical findings, diagnostic procedures, treatment, and prognosis of midgut volvulus were reviewed by a retrospective study. Between 1980 and 2005, 29 patients with midgut volvulus ranging in age from 1 day and 15 years were treated at HanYang University Hospital. Seventy-nine percent of the patients presented before 1 month of age. Midgut volvulus occurred 2 times more frequently in male. The clinical findings were bilious vomiting (96.6 %), irritability (34.5 %), abdominal distention (13.8 %), abdominal pain (10.3 %), and palpable abdominal mass (6.9 %). The diagnosis was made by abdominal simple x-ray (17.2 %), upper gastro-intestinal contrast study (37.9 %), abdominal sonogram (20.7 %), abdominal CT (3.4 %), and abdominal exploration (20.7 %). Among the 29 patients, 5 patients developed gangrene of small intestine due to strangulation and underwent resection of bowel. Two patients died due to sepsis.

Biliary atresia (BA) is the result of fibrosing destructive inflammatory process affecting intrahepatic and extrahepatic bile ducts, which lead to cirrhosis and portal hypertension. Kasai portoenterostomy has been the standard operative procedure in biliary atresia. Recently, there has been remarkable increase in the survival rate in cases of BA. However, long-term survivors are not clearly evaluated in Korea. To define long-term prognosis factors of patients who underwent surgery for BA, a retrospective study was undertaken of 10 (37 %) patients surviving more than 10 years among 27 patients who underwent one of Kasai procedures between 1981 and 1995. Hepatomegaly was present in 4 and splenomegaly in 7 patients. Serum bilirubin was normalized at 1 year after operation. Aspartate aminotransferase (AST, GOT), Alanine aminotransferase(ALT, GPT) were normalized at 12 years and alkaline phosphatase(ALP) was normalized at 13.5 years. Cholangitis developed mainly within 5 years after operation so close follow up is needed. Life long follow-up is needed because of progressive deterioration of liver function even after 10 years.

Intestinal duplication is a rare congenital anomaly. The diagnostic approach is difficult because of the differences in its location and clinical presentation. To evaluate the diagnostic as well as the therapeutic approaches in children, the medical records of 20 patients with intestinal duplications which had been operated upon from July 1980 to October 2002 were analyzed, retrospectively. The range of age was from 1 day to 11 years. The variables, such as age, sex, clinical presentation, diagnostic method, localization, anatomic type, treatment, complication, and combined anomalies were analyzed. Most of the cases were presented as incidental finding. The majority of the duplications except hindgut were cystic type. Treatment included segmental intestinal resection, excision of the lesion without intestinal resection, and septotomy. Seventy-five percent of the patients were detected before 1 year of age. The anatomic type of the lesion was closely related with its location. The cases of hindgut were almost always tubular type except 1 case. Clinical presentation was related to age, location, and anatomic type. There were no specific diagnostic methods. Perfect localization and application of appropriate operation are the most important requirements for successful treatment.

Preauricular sinus and preauricular skin tag are common childhood congenital anomalies. It is important for the pediatric surgeon to be familiar with the embryology and differentiation of head and neck structure to accurately diagnose and treat these lesions. Seventy-eight patients with preauricular sinus and twenty-eight with preauricular skin tag treated in the Department of pediatric surgery at Hanyang University Hospital from January 1981 to May 2002 were reviewed to determine relative frequency, clinical classification and appropriate treatment. The male to female ratio of preauricular sinus was 1:1.2, and preauricular skin tag was 1:1. The most commonly presenting age of sinus and skin tag was before 5 year (62.8%) and before 1 year (53.6%). Twenty nine of 78 cases of preauricular sinuses were on the left, 25 on the right and 24 bilateral. Sings of infectio were infection were seen in 73.0% of patients with preauricular sinus at operation. Only 31.3% of lesions were infected in patients less than one year of age, but 89.5% between 3-5 year and 100% between 5-8 year. Cartilage was present in five patients with preauricular skin tag. Although re-operation due to wound infection was necessary in four cases, no recurrences were found. The preauricular sinus is a common anomaly in childhood, and has had a relatively high recurrence rate. But most of the recurrence were due to incomplete resection because of combined infection. Initial proper diagnosis and early operation are very important. Identification of the exact anatomical location of sinus tract is necessary because total excision of the lesions including those tracts is the only way to prevent recurrence.

Branchial anomaly is a frequently occurring congenital abnormality in childhood. It is important for the pediatric surgeon alike to be familiar with the embryology and differentiation of head and neck structure to accurately diagnose and treat these lesions. Eighty-five patients with branchial anomaly treated at Hanyang University Hospital between 1980 and 2001 were reviewed to determine relative frequency, clinical classification and appropriate treatment. The male to female ratio of branchial anomaly was 1.2:1. The most commonly presenting age was before 1 year (32 %) and the age group between 1 and 3 year (22 %) followed it. According to the classification of branchial anomalies, 73 of 85 cases were second branchial anomaly, 9 had the first type and 3 did fourth type. One patient showed combined anomalies of the first and the second type. Infection sign were seen in 70 % of patients at the time of the first visit to our hospital and also patients' symptoms were frequently related with the infection. Forty-one cases (48 %) were fistula, 21 (25 %) were cysts, 21 (25 %) were sinuses, and two were only cartilage remnants. The most common type of the branchial anomalies is the second branchial fistula and the most common symptoms of the anomalies are related with infection. Initial proper diagnosis and anatomical classification of the anomalies are very important in managing the lesions. The efforts to find the exact anatomical location of the fistula or sinus tract are necessary because total excision of the lesions including those tracts is the only way to prevent recurrence.

Lymphangiomas or cystic hygromas are quite commonly seen in children. During a 22-year period, from January 1980 to December 2001, 117 patients with lymphangioma were treated and followed in the Department of Pediatric Surgery at Hanyang University Hospital. The male-to-female ratio was 1.9:1 (77:40) with a male preponderance. As for the age incidence at time of diagnosis, 10 (8.5 %) patients were noted under 1 month of age, 37 (31.6 %) were between 1 month and 1 year of age, 12 (10.3 %) between 1 and 2 years of age, so 59 (50.4 %) were under 2 years of age. Sixty one (52.1 %) lymphangioma-cases were located in the neck, including one case at the nape. Axilla was the second in frequency and the rest were scattered at various sites. The intrascrotal lymphangioma is very rare but we have experienced one case of primary intrascrotal lymphangioma. Eighteen (15.4 %) cases were located in the intraabdominal area, 10 in the mesentery, 2 in the greater omentum and 6 in the retroperitoneum. The chief complaints of intraabdominal lymphangioma were abdominal pain, intestinal obstruction, inguinal hernia, palpable mass, and/or abdominal distension. Among 77 histologically proven cases, 14 cases were cavernous lymphangiomas and the rest were cystic lymphangiomas. Bleeding in the lymphangioma was noted in 20 (17.1 %) cases of all. As for the treatment, a complete excision was performed in 77 (65.8 %) patients and AgNO3 sclerotherapy after incomplete excision was performed in 23 (19.7 %). Picibanil (OK-432) sclerotherapy was performed in 17 (14.5 %) patients. Recurrence rate was 7.7 % and mortality occurred in one case who had a large neck lymphangioma extending into the mediastinum.

Thyroglossal duct cyst is ectodermal remnant, which may develop along the line of descent of the thyroid gland from the foramen cecum of the tongue to the pyramidal lobe of the thyroid gland. Meticulous dissection of the cyst and duct, along with the body of the hyoid bone is necessary to avoid recurrence. Eighty-one patients with thyroglossal duct cyst treated at Hanyang University Hospital between January 1980 and December 2000 were reviewed to determine the incidence and to analyze the result of management. The male-to-female ratio was 1.4:1 (47:34) with a male preponderance. They are most commonly present at 3-8years (54.2%) of age, but rarely present at infancy. The most common symptom was a painless midline neck mass (76.5%, 62cases). Eighty-one patients underwent modified Sistrunk operation without evidence of recurrence. Eight-nine percent (72 cases) of these lesions were located between thyroid substance and hyoid bone, and 11% (9 cases) were above the hyoid bone. There were 22 infected cysts (27.2%). The Sistrunk operation is a gold standard for treating the thyroglossal duct cysts. For best results in thyroglossal duct cyst surgery, one should make every effort to remove the cyst intact in continuity with the body of the hyoid bone. In our institute, Sistrunk operation modified by the authors showed a good result.

Biliary atresia (BA) is very difficult to distinguish from neonatal hepatitis (NH) and its prognosis depends on the age at the time of Kasai operation. Therefore early differentiation between these two conditions is very important. Although various clinical and laboratory tests have been reported to differentiate between them, they are still of limited value. From 1980 to 1999, forty-five infants were referred to our pediatric surgical unit for operation for suspected BA. Eight patients underwent Kasai operation immediately because late diagnosis. These were excluded from the study. The clinical history, physical findings, radiologic and laboratory examinations of 37 cases were analyzed retrospectively. The average age of BA (n=20) was 55.1+/-6.7 days, and that of NH (n=17) was 55.8+/-5.6 days. The sex ratio of BA was 13:7, and that of NH was 14:3. All the patients had obstructive jaundice and acholic stool except 4 BA and 6 NH patients. Acholic stool with yellow component was more frequent in NH. Onset of jaundice was within 2 weeks after birth in 85% of BA, and in 65% of NH. The onset of acholic stool was within 2 weeks after birth in 60% of BA, and in 23.5% of NH. The duration of jaundice and acholic stool of BA were 50.9+/-6.6 days and 41.3+/-8.4 days and those of NH were 40.1+/-3.1 days and 26.6+/-5.4 days respectively. The ultrasonogram and hepatobiliary scan were useful, but not a definitively reliable method for the differentiation of these two diseases. There was no difference in laboratory data. Seventeen cases had NH among 45 referred cases for Kasai operation with the clinical impression of BA, and 4 cases of 17 NH cases needed to be explored to rule out BA. In conclusion, false positive rate of clinical impression of BA was 37.8%, and negative exploration rate was 8.9%. Therefore, careful clinical observation for 1-2 weeks by an experienced pediatric surgeon was very important to avoid unnecessary operation to rule out NH up to the age of 8 - 10 weeks, so long as the stool had yellow component.

Congenital anomalies in the head and neck region such as preauricular sinus and skin tag, thyroglossal duct cyst, branchial anomaly, cystic hygroma and dermoid cyst are common in pediatric population. It is important for pediatricians and pediatric surgeons to be familiar with the embryology and the anatomical characterics of these lesions in order to diagnose and treat properly. Three hundred nineteen patients with congenital head and neck anomalies treated at Hanyang University Hospital between 1980 and 1999 were reviewed to determine the relative frequency of the anomalies and to analyze the method of management. Eight-four patients(25.1%) of 335 lesions had preauricular sinus and skin tag, 81 patients(24.2%) had thyroglossal duct cyst, 81 patients(24.2%) had branchial anomaly, 58 patients(17.3%) had cystic hygroma, 31 patients(9.2%) had dermoid cyst. The male-to-female ratio was 1.4:1. The thyroglossal duct cyst was most commonly present at 3-5years, however branchial anomaly was commonly diagnosed in children younger than 1 year. Preauricular sinus shoeed familial tendency in three patients and bilaterality is 33.8%. Most head and neck anomalies in children had clinical and anatomical characterics. A careful history and physical examination were very useful for diagnosis and proper management. The initial surgery should be done by experienced pediatric surgeonsl since the recurrence rate after incomplete surgical excision could be high.

PURPOSE: In recent years, the authors experienced a distinctive clinical entity of multiple intestinal ulcerations and perforations in infants. The purpose of this study was to describe the clinical characteristics of this entity, examine th possible pathogenesis and the effective treatment. METHODS: Seven infants underwent abdominal exploration under suspicion of surgical abdomen and were noted to have multiple intestinal ulcerations and perforations without evidence of necrotizing enterocolitis by the members of the Korean Association of Pediatric Surgeons. The clinical courses, operative findings, bacterial cultures, pathologic findings, treatment and prognosis of these seven cases were evaluated retrospectively. RESULTS: The characteristics of this entity are as follows : The initial presenting symptoms were all different. Despite conservative treatment with a broad spectrum of antibiotics, diarrhea and abdominal distention developed and progressively grew worse. At laparotomy, all patients exhibited numerous typical transverse linear ulcerative lesions with pin-point perforations scattered mainly in the small bowel. Histologic evaluations of the resected specimens revealed mucosal ulcerations with neutrophil infiltration, submucosal microabscesses and colonies of gram-positive cocci. Methicillin-resistant Staphylococcus aureus(MRSA) was the predominant organism cultured from the body fluid. Only two cases, the completely-resected one and the one immediately treated with vancomycin after operation, survived. CONCLUSION: We think this distinct clinical entity exhibiting multiple intestinal ulcerations and perforations is caused by MRSA occurring in infants. It has a high mortality because it is verydifficult to diagnosis in young infants before laparotomy. Vancomycin is highly effective in treating MRSA, so we think the early diagnosis of this entity can make the treatment successful.

Ceramide, a product of sphingomyelin hydrolysis, is now recognized as an intracellular lipid messenger, which mediates the effects of extracellular agents on cellular growth, differentiation and apoptosis. Recently, ceramide has been implicated in the regulation of phospholipase D (PLD). In this study, we examined the effects of ceramide on the activity and mRNA level of PLD during apoptotic process in FRTL-5 thyroid cells. C2-ceramide (N-acetyl sphingosine) induced apoptosis in FRTL-5 thyroid cells. Fluorescent staining showed that ceramide induced the typical features of apoptosis including condensed or fragmented nuclei. DNA fragmentation was also observed by agarose gel electrophoresis. Flow cytometric cell cycle analysis showed more clearly that ceramide induced apoptotic cell death in FRTL-5 thyroid cells. The treatment of FRTL-5 thyroid cells with thyroid-stimulating hormone (TSH) resulted in an increased PLD activity in a dose- and time-dependent manner. However, the TSH-induced increase in PLD activity was down-regulated within 2 h after ceramide treatment. Furthermore, the levels of PLD mRNA were found to be decreased throughout apoptotic process as inferred by reverse transcription-polymerase chain reaction. However, the decreases in PLD mRNA levels were not correlated with those in PLD activities after ceramide treatment. Taken together, these data suggest that ceramide inhibits the PLD activity in an early apoptotic phase and down-regulation of the levels of PLD mRNA may be implicated in apoptotic process in FRTL-5 thyroid cells.

Among 60 children with teratoma, forty-three (71.7 percent) were girls and 17 (28.3 percent) boys. Primary sites were sacrococcygeal in 30 patients (50 percent), retroperitoneal in 12 (20 percent), ovarian in 11 (18.3 percent), testicular in 3 (5 percent), and one in each of nasopharyngeal, gastric, hepatic and pancreatic (1.6 percent, respectively). Fifty-five (91.7 percent) teratomas were benign and 5 (8.3 percent) malignant. Malignant teratomas were detected only at sacrococcygeal region (16.7 percent). Older than 2 months of age at diagnosis, presence of urinary and colonic obstructive symptoms, multiple masses and elevated serum alpha-fetoprotein were indicators of malignancy in sacrococcygeal region. Tumor size, presence of calcification, and gross appearance (cystic or solid) did not correlate with malignant nature. Thirteen (21.7 percent) cases were associated with other anomalies. For the immature teratoma, the operative resection without adjuvant chemotherapy was enough. Three malignant cases were survived, one with chemotheapy for 3 years and the others without chemotherapy for 5 and 10 years.

The pyloric length, diameter and muscle thickness were measured by ultrasonograms of 15 infants with infantile hypertrophic pyloric stenosis (IHPS) and were compared with the infants who came in for the routine vaccination randomly. This study analyzed the changes in pylorus for those who received pyloromyotomy using the ultrasonogram at 4 weeks and 8 weeks postoperatively, such as the time needed to become normalized, and compare with the size of the hypertrophic pylorus before the pyloromyotomy. According to Carver5, the pyloric muscle volume (PMV) and pyloric muscle index (PMI) were calculated in each case. The pyloric muscle volume, PMI and the thickness of pyloric muscle proved to be a more reliable guide to diagnose IHPS than length and diameter of pylorus. The pyloric muscle after pyloromyotomy was measured by ultrasound at 4 weeks and 8 weeks postoperatively. The pyloric muscle length, diameter, thickness and pyloric muscle volume were not normalized at 4 and 8 weeks postoperatively. However, pyloric muscle index was normalized at 4 weeks postoperatively which was probably due to rapid weight gain after pyloromyotomy.

Of 72 cases with vitelline duct and vessel remnants, 45 (62.5%) had symptomatic lesions (mean age, 27.9 months) with male preponderance (4.6: 1). Among the 45 symptomatic lesions, there were 22 cases of Meckel's diverticulum, 6 cases of Meckel's diverticulum with fibrous band attached to the umbilicus, 6 cases of patent vitelline duct, 5 cases of vitelline artery remnant as fibrous band, 2 cases of umbilical sinus, 2 cases of umbilical polyp, and 2 cases of vitelline cyst. Twenty three cases (51%) presented with intestinal obstruction, 6 (13%) with rectal bleeding, 4 (9%) with perforated Meckel's diverticulum, 5 with intestinal fluid drainage through umbilicus, 5 with umbilical lesion, and 1 with abdominal mass. Intestinal obstruction due to fibrous band developed at infancy (average age, 4.6 months). About 82% of complicated Meckel's diverticulum (n=28) presented less than 4 years of age. Seventeen Meckel's diverticulums, 8 obliterated vitelline artery remnants, and 1 vitelline vein remnant as fibrous band were found incidentally at laparotomy.

Parenteral nutrition has been an essential part of postoperative care of neonates requiring major surgery soon after birth followed by prolonged period of no allowable enteral feeding. 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 for esophageal atresia with tracheoesophageal fistula, gastroschisis and omphalocele at the Division of Pediatric Surgery, Hanyang University Hospital, 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 oral feeding. The mean urine output was maintained at 3.5 ml/kg/hour during TPN and at 3.6 ml/kg/hour during oral feeding. The increment of body weight observed during TPN was 132gm in TEF, 53gm in gastroschisis and 3gm in omphalocele patients, while loss of body weight was not oberved in each group. The mortality rate was 5.7% (3/53), related to underlying congenital anomalies but not to TPN. The common complications were 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. The result of the study suggests that peripheral TPN could be used for adequate postoperative nutritional support in neonates requiring about 2 to 3 weeks TPN.
