Cadaveric analysis of surgical techniques and working space for retroperitoneal tumors as model for improving resection of neuroblastoma.

Purpose: Neuroblastoma, the most common extracranial solid tumor in children under 5 years, often surrounds visceral arteries. This study aimed to analyze the working space provided by standardized surgical techniques at key arterial landmarks in adult cadavers.

Methods: We assessed in eight adult cadavers the mobilization of the left colon, spleen and pancreas, right colon, duodenum and mesenteric root, access to the bursa omentalis.

Stridor caused by duplication cyst in a female infant and temporary vocal cord paralysis. A case report.

Introduction And Importance: Congenital hypopharynx duplication cysts are a medical rarity; nevertheless, they offer an important differential diagnosis in neonatal dyspnea or feeding problems.

Case Report: Herein, we describe a case of delayed diagnosis but successful surgical removal of a large congenital hypopharynx cyst in a 4-month-old infant presenting with stridor.

Clinical Discussion: Early and proper diagnosis and surgical handling of hypopharynx cyst can help to achieve the best prognosis and outcome.

Ovarian torsion in the pediatric population: predictive factors for ovarian-sparing surgery-an international retrospective multicenter study and a systematic review.

Study Objective: Ovarian torsion (OT) in pediatric age is a challenging condition to diagnose and treat. To date, there is still no clear consensus about its management. Our aim was to assess some possible associated factors that can help surgeons in decision-making.

Pediatric Urachal Anomalies: Monocentric Experience and Mini-Review of Literature.

Background: Surgery is the current mainstay for the treatment of urachal anomalies (UA). Recent literature data support the theory of a spontaneous resolution within the first year of life. The aim of this study, comprising solely surgically treated children, was to identify age specific patterns regarding symptoms and outcomes that may support the non-surgical treatment of UA.

Meckel's Diverticulum in Children: A Monocentric Experience and Mini-Review of Literature.

Vitelline duct anomalies (VDA, including Meckel's diverticulum (MD)) result from failed embryologic obliteration. This study aimed for characteristics in symptomatic versus asymptomatic VDA, analyzing clinico-laboratory data from 73 children, aged 1 day to 17 years, treated at a tertiary Pediatric Surgery Institution from 2002-2017. A male preponderance was obtained (ratio 3.

The lymphocyte-to-monocyte ratio may distinguish complicated from non-complicated pediatric appendicitis: A retrospective study and literature review.

Background: To date, no parameter with satisfactory accuracy exists for the diagnosis of appendicitis. This retrospective study describes the discriminatory value of preoperative hematologic factors associated with complicated and non-complicated pediatric appendicitis.

Methods: Clinical and laboratory data were obtained from 294 children diagnosed with appendicitis on admission and treated at our tertiary-level pediatric hospital from 2015 to 2017; they were divided into three groups: control group (n = 118), histologically proven complicated (n = 120), and non-complicated (n = 56) appendicitis.

Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio Might Predict Pediatric Ovarian Torsion: A Single-Institution Experience and Review of the Literature.

Study Objective: To determine clinical and laboratory characteristics of ovarian torsion (OT; n = 28) compared with a non-OT control (OC; n = 64) group.

Design: Retrospective single-center review performed between January 2006 and December 2016.

Setting: Academic department of pediatric surgery.

[Flap Reconstruction as Alternative Anastomosis Technique for the Surgery of Oesophageal Atresia with Distal Oesophagotracheal Fistula].

Aim: The creation of a primary anastomosis in newborns with oesophageal atresia and distal oesophageotracheal fistula (EA-DF) is technically challenging, especially in small children. The goal is to approximate the fragile oesophageal ends without suture disruption and to minimize the mobilisation of the lower segment. We describe an alternative anastomosis technique aiming at reducing the tension on the first sutures at the posterior wall.

Does metabolic alkalosis influence cerebral oxygenation in infantile hypertrophic pyloric stenosis?

Background: This pilot study focuses on regional tissue oxygenation (rSO) in patients with infantile hypertrophic pyloric stenosis in a perioperative setting. To investigate the influence of enhanced metabolic alkalosis (MA) on cerebral (c-rSO) and renal (r-rSO) tissue oxygenation, two-site near-infrared spectroscopy (NIRS) technology was applied.

Materials And Methods: Perioperative c-rSO, r-rSO, capillary blood gases, and electrolytes from 12 infants were retrospectively compared before and after correction of MA at admission (T1), before surgery (T2), and after surgery (T3).

Volvulus in term and preterm infants - clinical presentation and outcome.

Aim: Our aim was to assess if term and preterm infants with volvulus showed different patterns with regard to pathogenesis, clinical presentation and outcome.

Methods: We reviewed the medical records and imaging data of infants aged less than six months with volvulus treated in a single surgical referral centre from 2006-2013.

Results: Volvulus was diagnosed in 19 infants, with no anatomical anomaly in three of the 12 preterm infants and one of the seven term infants.

Transumbilical cord access (TUCA) for laparoscopy in infants and children: simple, safe and fast.

Purpose: We herein report a case series evaluating the safety and complication rate of transumbilical cord access (TUCA) for pediatric laparoscopic surgery.

Methods: Data were collected for 556 infants and children. Access into the abdominal cavity was gained via a transverse infraumbilical stab incision passing the fibrotic umbilical cord remnant.

Posthemorrhagic hydrocephalus in extremely low birth weight infants: Ommaya reservoir vs. ventriculoperitoneal shunt.

Purpose: The aim of this study was to analyze morbidity and initial surgery in infants with posthemorrhagic hydrocephalus (PHH) by comparing infants who were treated with a subcutaneous cerebrospinal fluid reservoir (Ommaya reservoir = CSF_R) with infants who primarily received a ventriculoperitoneal shunt (VPS).

Method: Inclusion criteria were infants born between January 2006 and June 2014 who had a diagnosis of intraventricular hemorrhage (IVH) and underwent surgical intervention for hydrocephalus.

Results: Twenty-five infants, with a median gestational age (GA) of 26.

Totally transanal LESS pull-through colectomy: a novel approach for avoiding abdominal wall incision in children with long-segment intestinal aganglionosis.

Unlabelled: Abstract Introduction: Minimally invasive surgery in children with long-segment intestinal aganglionosis aims to reduce the number of abdominal wall incisions. Conventional laparoscopic and laparoendoscopic single-site (LESS) surgeries fulfill this goal. In children, natural orifice translumenal endoscopic surgery (NOTES™; American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society for American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) has been limited because of fear of access site complications.

Urgent resection of bleeding congenital mesenchymal chest wall hamartoma in an infant.

We report a case with prenatally diagnosed large cystic-solid mesenchymal chest wall hamartoma. An attempt of conservative management was made however repeated intralesional hemorrhage led to enlargement and severe anemia which required urgent resection at the age of 8 weeks. The infant had an unimpaired development over a follow-up of 4 years.

Pseudotumerous enlargement of the umbilical cord owing to an intra-amniotic varicosity associated with thrombocytopenia.

Herein, we describe a male infant with an antenatally diagnosed single umbilical artery and extensive varicosities of the umbilical vein with tumor-like appearances. Consumption coagulopathy occurred postnatally, and surgical resection of the umbilical cord led to a normalization of the platelet count.
