BACKGROUND: The etiology of choledochal cysts is unknown, but the theory of pancreatobiliary reflux through an anomalous pancreatobiliary ductal union (APBDU) is widely accepted. The aim of this study was to evaluate the correlation between choledochal cysts and APBDUs in children. METHODS: We retrospectively analyzed 33 pediatric patients with choledochal cyst who had undergone excision of the whole extrahepatic bile duct along with hepaticoenterostomy at the Division of Pediatric Surgery, Department of Surgery, Yonsei University College of Medicine, from 1993 to 1998. RESULTS: The mean age of the patients was 51 months, and the ratio of males to females was 1:2.3. Anatomical types were Ia (n=17, 52%), Ic (n=11, 33%), III (n=1, 3%), and IVa (n=4, 12%) in the Todani classification of biliary cysts. We performed endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography, or intraoperative cholangiopancreatography in all cases. An APBDU was identified in 24 patients (73%): right angle union (n=11, 33%), acute angle union (n=11, 33%), or a complex union (n=2, 6%) in the Todani classification of APBDUs. Type Ia cystic lesions correlated with right angle unions whereas Type Ic cylindrical lesions correlated with acute angle unions. The mean age of patients with a Type Ic, acute angle union was older than that of patients with a Type Ia, right angle union. In Type Ic, the amylase levels in serum and bile were elevated, but in Type Ia, they were not. CONCLUSIONS: APBDUs correlated highly with the shape of the extrahepatic dilatation, the age at onset, and the reflux of pancreatic juice. We think the excision of the entire extrahepatic duct along with a hepaticoenterostomy and appropriate evaluation of the APBDU are essential for the treatment of choledochal cysts in children.

BACKGROUND: Moxifloxacin is a newly developed drug which is more potent and safe compared to previous fluoroquinolones. This drug effectively eradicates organisms such as beta-lactamase-producing or other resistant bacteria. Moxifloxacin is known to be effective in treating respiratory infections such as Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Chlamydia pneumoniae, Legionella spp. and Mycoplasma pneumoniae. METHODS: In a multicenter, randomized, open, comparative study, the efficacy and safety of oral moxifloxacin taken 400 mg once a day and clarithromycin taken 500 mg twice daily for 7 days were compared for the treatment of Korean patients with acute exacerbations of chronic bronchitis. RESULTS: A total of 170 patients were enrolled, and they were divided into two groups:87 in the moxifloxacin group and 83 in the clarithromycin group. Of those enrolled, 76 (35 for bacteriologic efficacy) in the moxifloxacin group and 77 (31 for bacteriologic efficacy) in the clarithromycin group were included in the efficacy analysis. All were included in the safety analysis. Clinical success was noted in 70 (92.1%) of 76 moxifloxacin-treated patients and 71 (92.2%) of 77 clarithromycin-treated patients. Bacteriologic success rate seemed to be higher in moxifloxacin group (73.5%) than in clarithromycin group (54.8%), but statistically insignificant (p=0.098). Drug susceptibility among organisms initially isolated was higher in moxifloxacin group on Streptococcus pneumoniae, Pseudomonas aeruginosa, Klebsiella pneumoniae(p<0.001). Adverse events were reported by 12.8% of 86 patients receiving moxifloxacin and 21.7% of 83 patients receiveing clarithromycin. Headache (4.7% vs 4.8%, moxiflosacin group vs clarithromycin group, respectively) and indigestion (2.3% vs 6.0%, moxifloxacin group vs clarithromycin group, respectively) were the most frequent side effects in the two groups. CONCLUSION: This study demonstrated that for the treatment of acute exacerbations of chronic bronchitis a 7-days course of moxifloxacin 400 mg od was clinically equivalent and microbiologically superior to clarithromycin 500 mg bid.

This report present the result of the national survey of pediatric surgeons' preferences on diagnosis and treatment of Hirschsprung's disease(HD) carried out in 1993. The questionnaires were sent to twenty-seven members of the Korean Association of Pediatric Surgeons (KAPS) working in twenty-four institutions. The questionnaires were designed to determine the individual surgeon's preference for the methods of diagnosis and treatment of the disease. Twenty-three pediatric surgeons from twenty institutions returned completed forms. The total number of patients diagnosed with HD in 1992 was 190 in this group. The estimated incidence of HD was 1/3,900. The most important symptom was delayed meconium passing and the most preferred diagnostic procedure was barium study. Anorectal manometric examination was carried out by 13 pediatric surgeons and 19 confirmed the diagnosis before operation by rectal biopsy, 12 with full-thickness biopsy and 7 with suction. Frozen section biopsy during operation was done by 22 surgeons. Eight surgeons did one stage operation if the age of the patient is suitable. Definitive operation was usually done at the age of 6 to 11 months. The most preferred operation was Duhamel procedure done by 19. Enterocolitis was the most serious complication of HD. Most of patients had normal continence within 6 to 12 months after operation. The follow-up period was less than 6 years in 16 surgeons. The results were presented at the 9th annual meeting of KAPS in June of 1993. This is the first national survey of HD and it can provide guidelines of diagnosis and treatment of Hirschprung's disease even though it is not a detailed study of patient data.

To understand the current status of neonatal surgery in Korea, a suvey was made among the 27 members of Korean Association of Pediatric Surgeons. Response rate among surgeons was 78 perecnt, eighteen hospitals participated in this study. Five hundred and three cases of neonatal surgical patients were analyzed. In Korea, about 50% of cases were treated at the hospital in the capital city area. Regional number of patients were closely related to the regional population. Imperforate anus(19%), atresia/stenosis of gut(12%), and Hirschsprung's diseases(12%) were sitting at the top in the list. Majority of operation was done within the first week of life, especially during the first 24 hour period. Eighty per cent was major or so called index cases. Mortality in so-called index cases was 17%. High mortality was observed in patients with diaphragmatic hernia(47%), gastrointestinal perforation(65%) and esophageal atresia(28%). Low birth weight babies showed higher mortality in gastro -intestinal perforation, esophageal atresia and abdominal wall defect. These were compared to 1993 survey of Japanese Society of Pediatric Surgeons.
