Purpose: To report a nationwide survey on neuroblastoma conducted by the Korean Association of Pediatric Surgeons (KAPS) in 2020. Methods: The clinical data of pediatric patients diagnosed with and treated for neuroblastoma from 2005 to 2019 in 19 hospitals of KAPS members were collected. Survival and prognostic factor analyses were performed using the log rank test and Cox proportional hazard analysis. A p-value <0.05 was considered significant. Results: A total of 669 patients with neuroblastoma were registered for the study. The results were presented and discussed at the 36th annual meeting of the KAPS, which was held in Seoul on August 21, 2020. Conclusion This study provides information on patient demographics, prognostic outcomes, and comprehensive treatment outcomes for neuroblastoma. The study is expected to be an important reference for improving pediatric surgeons’ understanding and treatment of neuroblastoma.

Purpose: This study provides insights into the prevalence at birth, clinical characteristics, and outcomes of gastroschisis and omphalocele in Korea over the past decade, addressing the lack of localized data despite advanced healthcare capabilities. Methods: The study retrospectively analyzed data from 20 pediatric surgical centers in Korea from January 2012 to December 2021, including 269 patients diagnosed with gastroschisis or omphalocele. Data variables included gender, gestational age, birth weight, associated anomalies, type of defect, surgical interventions, and outcomes. Results: The study covered 269 patients, with 80 gastroschisis and 189 omphalocele cases. Gastroschisis prevalence at birth remained stable at 2.15 per 100,000 live births, while omphalocele increased to 5.08 per 100,000. Both conditions had similar gender ratios (0.95). Gastroschisis patients had lower birth weights (2,463.90±505.50 g) and smaller head circumferences (31.97±1.86 cm) compared to omphalocele patients (2,757.65±761.24 g, 32.78±2.64 cm). Omphalocele cases had more associated anomalies, especially cardiovascular issues. Prenatal diagnosis rates were high: 93.7% for gastroschisis and 86.4% for omphalocele. About 96.3% of gastroschisis and 84.1% of omphalocele patients were born in their treatment hospitals. Gastroschisis patients underwent surgery sooner (average 3.5 days) and started feeding later (16.5 days) than omphalocele patients (average 56.5 days to surgery, 6.6 days to start feeding). Hospital stays and follow-up durations were similar, averaging around 782.6 days for gastroschisis and 800.3 days for omphalocele patients. Survival rates were 89.7% for gastroschisis and 87.1% for omphalocele. Conclusion The study highlights the need for early diagnosis, centralized care, and specialized surgical approaches to optimize outcomes for gastroschisis and omphalocele patients in Korea. Enhanced prenatal screening and surgical protocols are recommended to improve these patients' prognosis.

BACKGROUND AND OBJECTIVES: With the increasing survival of preterm infants, pulmonary hypertension (PH) related to bronchopulmonary dysplasia (BPD) has become an important complication. The aim of this study was to investigate the characteristics and outcome of PH in preterm infants with BPD and to identify the risk factors for PH. SUBJECTS AND METHODS: We reviewed the records of 116 preterm infants with BPD cared for at a single tertiary center between 2004 and 2008. RESULTS: Twenty-nine (25%) infants had PH >2 months after birth. PH occurred initially at a median age of 65 days (range, 7-232 days). Severe BPD, a birth weight <800 g, long-term ventilator care and oxygen supplementation, a high ventilator setting, infection, and a patent ductus arteriosus (PDA) were related to PH based on univariate analysis (p<0.05). The infants who had longer oxygen supplementation were significantly more likely to have PH (odds ratio, 18.5; 95% confidence interval, 4.1-84.6; p<0.001). PH was improved in 76% of infants after a median of 85 days (range, 20-765 days). Four infants (14%) died. The death of 3 infants was attributed to PH. CONCLUSION: BPD was frequently complicated by PH. Although PH resolved in the majority of infants, PH in preterm infants with BPD can be fatal. Regular screening for PH and adequate management are required.

A female adnexal tumor of probable Wolffian origin (FATPWO) is a rare neoplasm believed to originate from Wolffian remnants because the tumors are located in areas where such remnants are abundant. Because FATPWO is so rare that tumor biological behavior is not well defined, especially in cases of ovarian tumors, the collection and investigation of all relevant data, including this case report, are thus crucial to identify the best possible treatment for this type of tumor. We report a 14-year-old girl presented with a huge ovarian tumor that is reminiscent of dysgerminoma on CT scan. Left salpingo-oophorectomy was perfomed. Because the pathologic report on frozen section was malignant neoplasm, additional surgical staging was performed. A ovarian tumor of probable Wolffian origin was diagnosed by the pathologist, finally. No adjuvant therapy was given and there was no clinical evidence of recurrence during the 19 months of follow-up.

We report a case of a 36 year old female with coronary artery obstructive disease(Left coronary osteal stenosis), who had been admitted due to severe headache and vomitting. In admission, she was diagnosed as moyamoya disease on cerebral angiogram. She had no history of hypertension, diabetes mellitus, hyperlipidemia, smoking. She had experienced angina for 2 years, and 1 year ago she ws diagnosed as bypass surgery with left main coronary artery angioplasty. In moyamoya disease, several portions of extracranial arteries have been found to be involved, but so far, only one case has been reported the coronary involvement on coronary angiogram in the world. And, there has not been a report about moyamoya disease combined with left main osteal lesion yet. This present case indicates that we need to exam for extracranial vascular system including the heart in moyamoya disease.

Leiomyomatosis peritonealis disseminata is a rare non-neoplastic proliferation of histologically benign smooth muscle that occurs in the alxlominal cavity of during the reproductive years of life, often giving rise to false choical imprwsion of d.isseminated carcinomatosis grossly, In 1952 Wilson & Peale described a condition which they called "multiple peritoneal leiomyomas". Taubert et al(1965) clearly delinated the features of the lesion and named it leiomyomatosis peritonealis disseminata(LPD). We report a case of leiomyomatosis peritonealis disseminata with a brief review of literatures.
