Thoracoscopic repair of tracheoesophageal fistula and esophageal atresia.

Purpose: To evaluate the safety and efficacy of the thoracoscopic repair of esophageal atresia and tracheoesophageal fistula (EA/TEF).

Methods: From August 2005 to March 2008, 23 consecutive patients (16 boys, 7 girls) weighing 1,070 to 3,390 g underwent thoracoscopic EA/TEF repair. Nine cases had associated malformations.

Laparoscopic splenectomy in children--a multicenter experience.

Purpose: Splenectomy is frequently required in children for various hematologic pathologic findings. Because of progress in minimally invasive techniques, laparoscopic splenectomy (LS) has become feasible. The objective of this report is to present a multicenter experience of 159 laparoscopic splenectomies.

[Diagnostic difficulties in pediatric abdominal pain with potential appendicitis].

Background: Pediatric abdominal pain is one of the most common symptom of children brought to attention of primary care physicians and pediatric surgeons. In many children clinical symptoms may be uncharacteristic and may lead to diagnostic difficulties.

Aim: Clinical analysis of children with right lower quadrant abdominal pain suspected of appendicitis or children with periappendicular mass.

Laparoscopic splenectomy in children: experience in a single institution.

Purpose: To assess the safety and effectiveness of laparoscopic splenectomy in children.

Materials And Methods: Hospital records of 63 patients who underwent laparoscopic splenectomy between 1998 and 2005 were reviewed retrospectively. In 16 patients concomitant cholecystectomy was performed.

[Diagnosis and treatment of thyroid cancer in children in the multicenter analysis in Poland for PPGGL].

Introduction: Differentiated thyroid carcinoma (DTC) in children presents different biological behavior in comparison to adults. Authors presents preliminary results of multicenter analysis concerning incidence, diagnostics and treatment of DTC in children.

Material And Methods: The study is a retrospective analysis of 107 pediatric patients from 14 academic centers based on the data from 2000 to 2005 obtained by questionnaire in hospitals involved in the treatment of DTC in children.

Percutaneous internal ring suturing: a simple minimally invasive technique for inguinal hernia repair in children.

Background: Laparoscopic herniorrhaphy in pediatric surgery is usually performed through three ports in the abdominal wall with intraperitoneal suturing. Our technique of percutaneous internal ring suturing (PIRS) requires only one umbilical port and needle puncture point. We describe the technique and evaluate the efficacy of percutaneous internal ring suturing for inguinal hernia repair in children.

Single nucleotide polymorphisms in the RET gene and their correlations with Hirschsprung disease phenotype.

Hirschsprung disease (HSCR) is a congenital, heterogeneous disorder, characterized by the absence of intestinal ganglion cells. Recent advances show that the RET gene is a major locus involved in the pathogenesis of HSCR. The aim of this study was to analyse if the HSCR phenotype in the Polish population is associated with the presence of polymorphisms in exons 2, 3, 7, 11, 13, 14 and 15 of the RET gene.

Assessing bladder capacity in children: is it feasible at all?

Aim: The aim of the study was to assess correlations between body parameters and bladder capacity in healthy schoolboys and schoolgirls. On the basis of those anthropometric data functional bladder capacity (FBC) in children was estimated.

Materials And Methods: The questionnaires were sent to 1,055 parents of children aged from 6 to 14 years.

[Increasing flow parameters and bladder capacity and its implication in maturing of lower urinary tract].

Unlabelled: THE AIM of the study was to estimate changes in urethral flow parameters and bladder capacity in children.

Material And Methods: Parents of 1055 children in the range of age 6-14 years were asked to fill a provided questionnaire. Parents of 466 children answered and agreed to have their child investigated.

[The role of ret gene in the pathogenesis of Hirschsprung disease].

Hirschsprung disease is a congenital disorder with the incidence of 1 per 5000 live births, characterized by the absence of intestinal ganglion cells. In the etiology of Hirschsprung disease various genes play a role; these are: RET, EDNRB, GDNF, EDN3 and SOX10, NTN3, ECE1, Mutations in these genes may result in dominant, recessive or multifactorial patterns of inheritance. Diverse models of inheritance, co-existence of numerous genetic disorders and detection of numerous chromosomal aberrations together with involvement of various genes confirm the genetic heterogeneity of Hirschsprung disease.

[Renal neoplasms in children].

Unlabelled: Nephroblastoma is the most common kidney tumor in Polish children.

Objective: to present clinical material and outcome of 533 children with renal tumors.

Material: 500 pts with nephroblastoma and 33 of non-Wilms: CMN, RCC,CSSK, RTK and others tumors were registered, mean age 4.

[Assessment of function of the only kidney in children after nephrectomy due to Wilms tumor].

Unlabelled: The aim of the study was to evaluate kidney function in children after unilateral nephrectomy caused by Wilms' tumour. The study included 40 former patients of the Department of Paediatric Surgery, who underwent complex therapy of Wilms' tumour at the age from 6 months to 8 years (mean 3.42 +/- 2.

Results of p53 analysis in pediatric malignancies in Poland.

Background: Mutations of the p53 gene are thought to be causally associated with the development of various neoplasms. In tumors overexpressing the wild-form of p53, its functional inactivation has been suggested, and MDM2 seems to be important in this process. We analyzed p53 in childhood solid tumors, as data on pediatric malignancies are still limited.

[Mediastinal tumors in children].

Mediastinal tumours are not very common among various tumours in children. The aim of our study was to evaluate the clinical features, diagnostic approaches and surgical management in 125 patients treated in our Department for 30 years. There were 39 lesions in the anterior, 21 in the medial and 49 in the posterior mediastinum.

[Prenatal diagnosis of congenital anomalies requiring surgical management in the Lower Silesia--fact or fiction?].

In order to assess the current status of prenatal diagnosis of congenital anomalies requiring surgical management in the area of Lower Silesia, a retrospective study of medical charts of all neonates admitted to the Department of Paediatric Surgery in Wrocław between 1997 and 2000 was undertaken. 218 babies affected by anomalies detectable antenatally by conventional ultrasound scan were subjected to the further study. Neural tube defects and abdominal wall defects were the most common and were diagnosed in 63 and 38 children respectively.
