Intestinal obstruction as a result of intra-abdominal hematoma: a complication of low molecular weight heparin in pediatric patients.

Introduction: Hematomas are a rare cause of intestinal obstruction. Subcutaneous heparin can bring about direct punctures on small bowel loops, potentially leading to traumatic hematoma and intestinal obstruction.

Case Reports: We present three cases of pediatric patients with clinical signs of intestinal obstruction treated with subcutaneous heparin.

Pediatric Plexiform Fibromyxoma: A Case Report.

The plexiform fibromyxoma is a rare mesenchymal tumor in adults that generally originates in the antrum of stomach, being its occurrence in pediatric patients exceptional. It was classified as a distinct entity by World Health Organization in 2010. No recurrences and metastases have been documented in many of the reported patients to date, being the surgical treatment curative.

Use of non-invasive scales for detecting esophageal varices in paediatric patients with portal vein thrombosis.

Introduction: Portal vein thrombosis (PVT) is the most frequent cause of portal hypertension in paediatric population. Baveno VI Consensus considers endoscopic variceal ligation as the second therapeutic option after meso-Rex bypass (surgical shunt).

Aim: Analyse the diagnostic profitability of non-invasive scales in order to predict the risk of oesophageal varices (OV) in children with PVT.

Analysis of esthetic assessment scales in two surgical approaches for hypertrophic pyloric stenosis.

Introduction: Hypertrophic pyloric stenosis (HPS) is a frequent pathology in neonates, with extramucosal pyloromyotomy being a healing surgery. It may be performed through a transverse subcostal incision (TSI) or a transumbilical incision (TUI).

Objective: To compare complications, operating times, hospital stay, and esthetic results between both techniques.

Analysis of the Predictive Capacity of the Clinical Variables That Indicate the Performance of Voiding Urosonography in the Study of Vesicoureteral Reflux in Children.

Introduction: Voiding urosonography (VUS) is a dynamic imaging technique which evaluates the lower urinary tract by introducing sonographic contrast into the bladder, preferably used in the diagnosis of vesicoureteral reflux (VUR). Our goals were to describe the clinical indications for performing a VUS for VUR's diagnosis and analyse its diagnostic reliability.

Material And Methods: Cross-sectional study carried on patients under 15 years old with a VUS taken between November 2013-2020.
