Materials And Methods: Patients with left grade 3 varicocele indicated for surgery were prospectively enrolled and randomly allocated to the scrotal antegrade sclerotherapy and laparoscopic Palomo surgery groups, with their respective contralateral normal testes taken as controls.

Comparison of scrotal antegrade sclerotherapy and laparoscopic Palomo surgery in treatment of adolescent varicocele: A 15-year review.

Introduction/objective: Varicocele is a common condition seen in adolescence and associated with adult subfertility. Numerous types of intervention have been described with differences in success and complication rates. This study aims to review and compare the surgical outcomes of laparoscopic Palomo surgery and scrotal antegrade sclerotherapy at our center.

Surgical Outcome Analysis of Pneumovesicoscopic Ureteral Reimplantation and Endoscopic Dextranomer/Hyaluronic Acid Injection for Primary Vesicoureteral Reflux in Children: A Multicenter 12-Year Review.

Objective: Vesicoureteral reflux (VUR) is a common condition associated with childhood urinary tract infection (UTI), which may lead to chronic renal failure and hypertension. Different antireflux approaches were advocated with differences in morbidity and success. The aim of this study is to review and analyze the surgical outcomes of pneumovesicoscopic ureteral reimplantation and endoscopic injection of dextranomer/hyaluronic acid (Dx/HA) in three tertiary centers.

D-dimer level correlation with treatment response in children with venous malformations.

Aim: Localized intravascular coagulopathy is present in children with venous malformations (VMs) as evidenced by elevated D-dimer levels. Few studies have looked into the changes in D-dimer after sclerotherapy and its correlation with treatment outcome and complications. Our study aims to investigate changes in D-dimer in children with VMs undergoing alcohol sclerotherapy.

Are all patients with short segment Hirschsprung's disease equal? A retrospective multicenter study.

Background/purpose: Short segment Hirschsprung's disease (HSCR) carries a better prognosis than long segment disease, but the definition of short is controversial. The objective of this study is to determine anatomically the extent of disease involvement that would be associated with a better functional outcome.

Methods: This is a retrospective multicenter (n = 3) study with patients (≥ 3 years) who had transanal pullthrough operation done for aganglionosis limited to the recto-sigmoid colon were reviewed.

Venous Malformation and Localized Intravascular Coagulopathy in Children.

 Localized intravascular coagulopathy (LIC) has been described in adults with venous malformation (VM) but rarely reported in children. This study aims to determine the prevalence of LIC in children with VM and associated risk factors.  Patients younger than 18 years with VM from 2010 to 2014 were reviewed.

Changes in Nasal Configuration Following Primary Rhinoplasty: Direct Anthropometric Measurement in Patients With Complete Unilateral Cleft Lip and Palate.

Background: With the recent advances of surgical adjuncts including presurgical naso-alveolar molding and postoperative nasal stenting, information on the anthropometric evaluation of cleft lip nasal symmetry after primary rhinoplasty is lacking.

Method: Twenty-nine nonsyndromic patients with complete unilateral cleft lip and palate undergoing modified rotation advancement cheiloplasty with synchronous primary rhinoplasty in our center were prospectively recruited in our study. All of them received our center's peri-operative management protocol, including presurgical naso-alveolar molding and postoperative nasal stenting.

Pancreatic kaposiform hemangioendothelioma presenting with duodenal obstruction and kasabach-merritt phenomenon: a neonate cured by whipple operation.

Aim Kaposiform hemangiondothelioma (KHE) is a rare vascular tumor, commonly associated with Kasaback-Merritt phenomenon characterized by thrombocytopenia and consumptive coagulopathy. We report a case of pancreatic KHE presenting with neonatal duodenal obstruction and Kasaback-Merritt phenomenon. Case Report A full term male baby presented with bile stained vomiting on Day 3 of life.

From observation to aetiology: a case report of a twin fetus-in-fetu and a revisit of the known rarity.

A baby girl presented with an antenatal diagnosis of a retroperitoneal tumour. Postnatal imaging suggested that this mass contained two fetiform structures with spine and long bone formation. This teratomatous mass was completely excised at 3 weeks of age.

Management of the low-flow head and neck vascular malformations in children: the sclerotherapy protocol.

Aim: Image-guided sclerotherapy is becoming the preferred treatment for low-flow vascular malformations in head and neck region. The authors review the management protocol for this condition and evaluate its clinical outcomes.

Methods: Children with low-flow vascular malformations in head and neck region undergoing sclerotherapy from 2010 to 2013 were reviewed.

Hong Kong Chinese parents' attitudes towards circumcision.

Objective: To investigate Hong Kong Chinese parents' knowledge and attitudes towards phimosis and circumcision.

Design: Questionnaire survey.

Setting: Four primary schools in Hong Kong.

Retroperitoneal pelvic packing for haemodynamically unstable pelvic fractures in children and adolescents: a level-one trauma-centre experience.

Purpose: This study aims to review the outcomes of haemodynamically unstable paediatric patients with pelvic fractures undergoing protocol intervention of retroperitoneal pelvic packing (RPP) with external fixation and angiography.

Methods: From 2004 to 2011, consecutive patients younger than 19 years treated in our centre for haemodynamically unstable pelvic fractures were retrospectively reviewed. From 2008, protocol intervention triad of external fixation, RPP, and angiography with embolization was implemented.

Serial transverse enteroplasty for short bowel syndrome: Hong Kong experience.

Objective: To report our experience with the first series of serial transverse enteroplasty operations (a novel bowel-lengthening procedure for patients with short bowel syndrome). DESIGN. Case series.

Sonic hedgehog signaling protects human hepatocellular carcinoma cells against ionizing radiation in an autocrine manner.

Purpose: Sonic hedgehog (Shh) signaling is critical to embryogenesis and resistance to chemotherapy. We aimed to examine the role of Shh signaling in the response to radiation of human hepatocellular carcinoma (HCC) cells.

Methods And Materials: Response to ionizing radiation therapy (RT) was evaluated by clonogenic assay.

An unusual cause of intestinal obstruction in an adolescent: a case report and management review.

A 15-year-old boy presented with intestinal obstruction two weeks following a blunt abdominal trauma. He had progressive bilious vomiting without abdominal distension or peritonitis. The contrast computed tomography (CT) scan of the abdomen provided the definitive diagnosis: there was an obstructing duodenal hematoma, which might have been slowly progressing or have arisen from secondary hemorrhage after the initial injury.

Complications of peptic ulcer disease in children and adolescents: minimally invasive treatments offer feasible surgical options.

Purpose: Surgery for complications of peptic ulcer disease (PUD) carries a significant morbidity and even mortality. The aim of this study was to determine the efficacy, safety, and outcome of children and adolescents undergoing minimally invasive treatment of bleeding and perforation complicating PUD.

Methods: One hundred thirty-two consecutive patients aged 6 to 17 years managed endoscopically for bleeding and laparoscopically for perforation from January 1999 to February 2006 were reviewed.

Electrogastrography in the management of pediatric functional dyspepsia and motility disorder.

Purpose: Electrogastrography (EGG) is a noninvasive investigation for recording gastric myoelectrical activity. We hypothesize that children with functional dyspepsia (FD) and gastrointestinal (GI) motility disorder have abnormal gastric myoelectrical activity. We aim to study the dyspepsia symptom scores and EGG of these children and compare them with those of the normal population.
