Does body weight below 6 kg modify survival of infants after liver transplant? Complete National Transplant Registry Data.

Objective: To determine the impact of infant recipient body weight at primary liver transplantation (LT) on both recipient and graft survival rates in complete national data from Poland.

Methods: We conducted a single-center, retrospective cohort study including 142 LT recipients below 1 year of age with body weights below 10 kg who received primary and isolated LT between 2001 and 2017. Patients were divided into two study groups according to body weight at the time of LT: (1) Group I (≤6.

Pediatric perianal Crohn's disease behavior in the era of biologic therapy.

Aim Of The Study: To describe perianal Crohn's disease behavior and the role of biological therapy in a sample of pediatric patients.

Methods: A retrospective study of pediatric patients with Crohn's disease (CD) treated in our institution from 2017 to 2021, with a minimum follow up period of 6 months, was conducted. Patients were divided whether they had perianal disease (PD) or not.

Intraoperative Troponin Elevation in Liver Transplantation Is Independently Associated With Mortality: A Prospective Observational Study.

Intraoperative factors implicated in postoperative mortality after liver transplantation (LT) are poorly understood. Because LT is a particularly demanding procedure, we hypothesized that intraoperative myocardial injury may be frequent and independently associated with early postoperative outcomes. We aimed to determine the association between intraoperative high-sensitivity troponin (hsTn) elevation during LT and 30-day postoperative mortality.

[Meconium periorchitis prenatal diagnosis: review of the literature, about 3 cases].

Objective: To assess the importance of prenatal ultrasound diagnosis of the fetus carrying meconium periorchitis and its predictive relevance for fetal monitoring and prognosis in the context of acute fetal intestinal disease.

Material And Methods: Three male fetuses have been diagnosed of meconium periorchitis in our Unit of Fetal Medicine in the last 5 years. Their prenatal ultrasound diagnoses were: testicular tumor (n=1); Meconium periorchitis with acute fetal intestinal perforation (n=2).

Treatment of undifferentiated embryonal sarcoma of the liver in children--single center experience.

Background: Undifferentiated embryonal sarcoma of the liver (UESL) represents less than 5% of all malignant hepatic tumors in childhood. It is considered an aggressive neoplasm with an unfavorable prognosis. The aim of this paper is to present a single center experience in the treatment of children with UESL.

Pulmonary artery growth in univentricular physiology patients.

Background: A Fontan-type operation, i.e. a connection of the systemic veins and pulmonary arteries without subpulmonary ventricle, with different surgical techniques, is nowadays the only treatment option for patients with a functionally univentricular heart (UVH).

Major infection after pediatric cardiac surgery: external validation of risk estimation model.

Background: A multivariable risk estimation model, in which the primary outcome was major infection, was recently developed and published using The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database. We have applied this risk estimation model to our congenital heart surgery program over a 16-year time interval to validate this risk estimation model and verify its specific risk factors for major infection.

Methods: Using complete and verified data, we selected patients in whom major procedures had been classified using both Aristotle Basic Score and Risk Adjustment for Congenital Heart Surgery (RACHS-1) and created a multivariable model in which primary outcome was major infection (septicemia, mediastinitis, or endocarditis).

Complications and late outcome in transperitoneal laparoscopic heminephrectomy for duplex kidney in children.

Purpose: We report our experience with laparoscopic heminephrectomy (LH) in children with duplex kidneys, emphasizing complications and late outcomes, and including anatomic and functional aspects.

Patients And Methods: We retrospectively reviewed medical data of 28 children with a duplex kidney who underwent LH. Complications were evaluated according to the Savata and Clavien classiffication systems.

Slide tracheoplasty in an infant with congenital tracheal stenosis and oesophageal atresia with tracheoesophageal fistula.

Slide tracheoplasty has become the treatment of choice when dealing with congenital tracheal stenosis (CTS). Versatility and effectiveness are the specific advantages of this technique when compared with other surgical procedures for tracheal reconstruction. We report a new use of slide tracheoplasty in a patient with a short CTS and a tracheal pouch after oesophageal atresia with tracheoesophageal fistula repair.

Analysis of 14,843 neonatal congenital heart surgical procedures in the European Association for Cardiothoracic Surgery Congenital Database.

Background: Early outcomes of congenital heart surgery in neonates have significantly improved during the last decade. Further improvements require identification of specific risk factors correlating with early mortality and morbidity.

Methods: Between January 1999 and May 2008 data on 14,843 congenital heart procedures performed in 118 congenital heart surgery centers in 34 countries were submitted to the European Association for Cardiothoracic Surgery Congenital Database.

Risk factors for cardiac arrhythmias in children with congenital heart disease after surgical intervention in the early postoperative period.

Objective: Early postoperative arrhythmias are a recognized complication of pediatric cardiac surgery.

Methods: Diagnosis and treatment of early postoperative arrhythmias were prospectively analyzed in 402 consecutive patients aged 1 day to 18 years (mean 29.5 months) who underwent operation between January and December 2005 at our institute.
