Congenital duodenal obstruction is a complex entity with various etiologies and often includes multiple concomitant disorders. Timely diagnosis and aggressive surgery are key to improving prognosis. Care should be taken to address all of the causes of duodenal obstruction and/or associated alimentary tract anomalies during surgery.
BackgroundWilms tumor (WT) is the most common renal malignant tumor in children. It occurs primarily at preschool age. The purpose of this review is to present current standards of diagnosis and treatment of WT around the world.Data sourcesAll the recent literature on diagnosis and treatment of WT were searched and reviewed.ResultsMost cases with WT are sporadic. The current survival in patients with WT is high (90%). Involvement of mutidisciplinary collaborative groups in the diagnosis and treatment of WT. National Wilms Tumor Study Group (NWTSG)/Children’s Oncology Group (COG) and The International Society of Paediatric Oncology (SIOP) are two major guidelines used for the current management of WT worldwide. The major difference exists in the two guidelines is the timing of surgery: SIOP recommends using preoperative chemotherapy, and NWTSG/COG prefers using primary surgery before any adjuvant treatments.ConclusionsMost patients with WT have good overall survival outcomes. Further studies should be highlighted on how to use chemotherapy and radiotherapy under more accurate risk-stratified strategies. Surgeons must be more focusing on how to maximize preoperative and postoperative treatment possibilities for achieving optimal results of patients with WT.
Gastric outlet obstruction (GOO) presenting beyond the newborn period is a relatively rare condition, when infantile hypertrophic pyloric stenosis (IHPS) is excluded. This report describes the clinical features, evaluation and management of 18 patients with GOO which was not caused by IHPS. The sex, age, and main presenting features were recorded on admission. Hemoglobin estimation, serum chemistry and blood gas analysis were also assessed in these patients. The diagnosis was confirmed with gastrointestinal barium, B ultrasound, gastroscopy, or at surgery. Some of them underwent gastroscopy with biopsy sampling for rapid urease test or histologic examination with Giemsa stains for Helicobacter pylori. Thirteen patients had peptic ulcer disease, of which six were successfully treated with medications. While the other seven needed operative management which included Heineke-Mikulicz pyloroplasty, gastroduodenostomy or gastrojejunostomy, respectively. All the patients who had Heineke-Mikulicz pyloroplasty or gastrojejunostomy developed bile reflux gastritis that could be alleviated with omeprazol. None of the patients developed dumping syndrome, failing to thrive, or anemia. Three children with antral diaphragm recovered without any complications by diaphragm excision with Heineke-Mikulicz pyloroplasty. The pylorus was compressed by fibrotic band in one 30-month boy, and he recovered uneventfully with Heineke-Mikulicz pyloroplasty during 10-year follow-up. Gastric outlet obstruction secondary to ingestion of sulfuric acid was noted in one patient, and he was successfully treated with gastroduodenostomy. Our data suggests that the satisfactory results could be expected in children with GOO with different therapeutic modalities based on the specific cause and degree of obstruction.
Radiofrequency ablation (RFA) has been widely reported as a minimally invasive treatment for liver tumours in adults, but has not been documented as a treatment for hepatoblastoma in a child. We report a 2-year-old boy with local recurrence of hepatoblastoma after partial hepatectomy. Percutaneous RFA was performed under real-time sonographic guidance. There was no imaging evidence of recurrence after a follow-up of 2 years. We consider this a promising technique in children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
