Congenital esophageal stenosis (CES) is a narrowing of the esophageal lumen from birth. Three types of CES have been described; tracheobronchial remnants (TBR), membranous web (MW), and fibromuscular stenosis (FMS). We reviewed the clinical features and the surgical outcome of 14 patients, pathologically confirmed as CES. Nine patients had TBR, 3 FMS, and 2 MVV. The mean age at operation was 3.8 years. Five patients were boys and 9 girls. Four patients had other congenital anomalies. Segmental resection of the lesion and end to end anastomosis was utilized in all cases except one who underwent myotomy. The stenotic segment was located at the distal esophagus in all patients. There were 8 complications in 6 patients, but no mortality. The mean follow-up period was 68 months. There were no feeding problems but 3 patients had minor gastroesophageal reflux. Our result indicates that segmental resection and anastomosis is a satisfactory surgical procedure in the management of CES.

Background and Objectives： Larynx granuloma is a exophytic inflammatory mass and may result from gastroesophageal reflux disease and a traumatic or prolonged endotracheal intubation. There has been a controversy in the treatment of larynx granuloma. Our aim of study is to know the results of the conservative management and surgery for larynx granuloma. Materials and Methods : We have reviewed and analyzed medical records of 71 Patients who were diagnosed and treated as larynx granuloma in Asan medical center from 1989 to 2000 retrospectively. And questionnaires on present patient's status were answered via telephone. Results : Forty four cases were treated by conservative management and 29 cases were treated by surgery. The total Percentages of improvement after treatment were 85.7 o/o after conservative management and 75.9% after surgery. In intubation granuloma percentages of improvement were 86.4% after conservative management and 73% after surgery. In contact granuloma percentages of improvement were 85% after conservative management and 78.5% after surgery. Conclusion : Resolution and treatment periods are longer in contact granuloma compared to intubation granuloma in the groups of conservative management. (P＜0.05) There is no significant difference of their outcome between conservative management and surgery. (P＞0.05) Although this study is retrospective, conservative management is the first treatment in the management of larynx granuloma.

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 $2,960{\pm}400g$ (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.

Purpose: The aim of this study was to evaluate the shortterm outcome of a jejunal interposition, by comparing it with a conventional Roux-en-Y gastrojejunostomy, after a total gastrectomy. Materials and Methods: For 28 patients (20 men and 8 women) with a gastric adenocarcinoma, who underwent an isoperistaltic simple jejunal interposition, weight, hemoglobin, hematocrit, serum protein and albumin, and cholesterol levels were checked before the operation and at 1 year and 2 years after the surgery. Also, endoscopy was performed to confirm reflux esophagitis. In this study, the data were collected between January 1993 and July 1999 at Chungnam National University Hospital, and the results were compared with those of the Roux-en-Y procedure. Results: The body weights at 1 year and 2 years after the surgery had returned to $86.0\%$ and $87.6\%$ of the recent original body weight in the jejunal interposition (JI) group and to $90.8\%,\;87.0\%$, respectively in the Roux-en-Y (RY) group. The levels of hemoglobin (g/dl) were 13.3, 12.5, and 11.9 in the JI group, and 13.8, 12.6, and 12.1 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum protein (g/dl) levels were 7.1, 7.2, and 7.5 in the JI group and 7.1, 7.0, and 7.2 in the RY gropu at the time of the operation and at 1 year and 2 years after the surgery, respectively. The serum albumin (g/dl) levels were 4.2, 4.1, and 4.2 in the JI group and 4.2, 4.2, and 4.2 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum cholesterol (mg/dl) levels were 186.5, 174, and 164 in the JI group and 213.7, 171.1, and 141.0 in the RY group at the time of the operation and at 1 year and 2 years after the surgery, respectively. The endoscopic finding showed that reflux esophagitis occurred in $7.1\%$ of the patients in the JI group and in $3.5\%$ in the RY group. Conclusion: We think that from the view point of quality of life, a jejunal interposition, as well as a Roux-en-Y procedure, is a useful reconstruction methods for a total gastrectomy.

Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

Purpose: Although the American Academy of Pediatrics provides clinical guidelines for urinary tract infection (UTI) infants, guidelines are not appropriate for neonates and infants less than 2 months of age due to insufficient data. The aim of this study was to evaluate the characteristics of neonates and young infants less than 2 months old (group 1) with UTI compared to older infants from 2 to 12 months old (group 2). Methods: We reviewed UTI patients aged 0 to 12 months admitted to the pediatric department in the last 5 years. Clinical characteristics such as age, sex, fever duration, recurrence, progression to acute pyelonephritis (APN), malformations like hydronephrosis and vesicoureteral reflux (VUR), and laboratory results were compared between group 1 and group 2. Results: 615 patients were included in this study. Group 1 had 94 cases and group 2 had 521 cases. Escherichia coli was the most commonly isolated pathogen in urine cultures. Fever duration was shorter in group 1 (vs.) 2 ($1.91{\pm}1.43$ days vs. $3.42{\pm}2.40$ days, P<0.05). As compared to group 2, group 1 had a higher proportion of patients with antenatal hydronephrosis and hydronephrosis found after admission (10.6% vs. 3.6% and 75.5% vs. 55.9%, P<0.05). There were differences between two groups in white blood cell (WBC) count (Group 1: $13,694{\pm}5,315/{\mu}L$, Group 2: $15,271{\pm}6,130/{\mu}L$, P<0.05) and C-reactive protein (Group 1: $32.02{\pm}35.17mg/L$, Group 2: $46.51{\pm}46.63mg/L$, P<0.05). Conclusion: Compared to older infants, UTI in neonates and young infants shows milder clinical manifestations except higher rates of hydronephrosis but outcome is alike.

Purpose: This study was performed to review the outcomes of gastrostomy insertion in children at our institute during 10 years. Methods: A retrospective chart review was performed on 236 patients who underwent gastrostomy insertion from October 2005 to March 2015. We used our algorithm to select the least invasive method for gastrostomy insertion for each patient. Long-term follow-up was performed to analyze complications related to the method of gastrostomy insertion. Results: Out of 236 patients, 120 underwent endoscopic gastrostomy, 79 had laparoscopic gastrostomy, and 37 had open gastrostomy procedures. The total major complication rates for endoscopic gastrostomy insertion, laparoscopic gastrostomy insertion, and open gastrostomy were 9.2%, 8.9%, and 8.1%, respectively. The most common major complication was gastroesophageal reflux requiring Nissen fundoplication (3.8%), and other complications included peritonitis (1.3%), hiatal hernia (1.3%), and bowel perforation (0.8%). Gastrostomy removal was successful in 8.6% and 5.0% of patients in the endoscopic and surgical gastrostomy groups, respectively. Gastrocutaneous fistula occurred in 60% of surgically inserted cases, requiring a second operation. Conclusion: This retrospective study was performed to review the outcome of gastrostomy insertion, as well as to introduce an algorithm that can be used for future cases. Further studies should be conducted to make a consensus on choosing the most appropriate method for gastrostomy insertion.

목적: 지역 사회 획득 열성 요로 감염 환자에서 extended-spectrum ${\beta}$-lactamase (ESBL) 생성 균주의 임상적 의의에 대해 알아보고자 하였다. 방법: 2011년 1월 1일부터 2013년 12월 31일까지 가천대 길병원에서 지역 사회 획득 열성 요로 감염으로 치료받은 18세 이하 소아 청소년 환자들을 ESBL 양성군과 음성군으로 구분하여 각 군의 임상 양상을 의무기록을 토대로 후향적으로 분석하였다. 결과: 연구 대상 기준을 만족하는 374건 중 ESBL 생성 균주에 의한 요로 감염은 13.1% (49건)이었다. ESBL 생성 균주의 비율은 E. coli 와 Klebsiella spp.가 각각 13.6% (48/354)와 5.0% (1/20)이었다. ESBL양성군과 음성군에서 발열 소실 기간($4.2{\pm}2.7$일 대 $3.7{\pm}2.1$일, P=0.10)과 멸균율(100% 대100%)은 차이가 없었다. ESBL 생성 여부와 관계 없이 방광 요관 역류가 동반되었을 경우에 신 겉질결손이 발생한 경우(41.9%)는 ESBL 생성 균주에서 신 겉질 결손이 발생한 경우(3.2%) 보다 많았다(P <0.05). 결론: 소아 열성 요로 감염 환자에서 원인 균주의 ESBL 생성 여부는 신 겉질 결손과 임상 경과에 차이가 없었다. 지역사회 획득 요로감염의 치료에서 항생제를 신중하게 선택해야 하며 ESBL 생성 균주에 대한 지속적인 감시가 필요하다.
