Esophageal replacement in children - 27 years of experience in a University Hospital.

Introduction: esophageal replacement in children is indicated when it is impossible to maintain the native esophagus, which in the pediatric population includes patients with esophageal atresia and esophageal caustic stenosis. The objective of this communication is to report the experience of a university service with two techniques of esophageal replacement.

Methods: this is a retrospective study based on the revision of hospital files.

Analysis of the efficacy and safety of conservative treatment of blunt abdominal trauma in children: retrospective study. Conservative treatment of blunt abdominal trauma in children.

Introduction: in Brazil, trauma is responsible for 40% of deaths in the age group between 5 and 9 years old, and 18% between 1 and 4 years, and bleeding is the leading cause of preventable death in the traumatized child. Conservative management of blunt abdominal trauma with solid organs injury - started in the 60s - is the current world trend, with studies showing survival rates above 90%. The objective was to assess the efficacy and safety of conservative treatment in children with blunt abdominal trauma treated at the Clinical Hospital of the University of Campinas, in the last five years.

Laparoscopic Transposition of Lower Pole Crossing Vessels (Vascular Hitch) in Children with Pelviureteric Junction Obstruction: How to Be Sure of the Success of the Procedure?

Background: To report a series of children with pelviureteric junction obstruction (PUJO) due to lower polar crossing vessels who underwent laparoscopic vascular transposition. In order to confirm the relief of the obstruction and avoid unnecessary additional procedures, we suggest performing an intraoperative measure of the ureteral opening pressure.

Patients And Methods: From January 2007 and January 2014, 11 children underwent laparoscopy to treat well-documented PUJO by polar vessels.

Cross-sectional study comparing different therapeutic modalities for cystic lymphangiomas in children.

Objective: Here, we describe our experience with different therapeutic modalities used to treat cystic lymphangiomas in children in our hospital, including single therapy with OK-432, bleomycin and surgery, and a combination of the three modalities.

Methods: We performed a retrospective, cross-sectional study including patients treated from 1998 to 2011. The effects on macrocystic lymphangiomas and adverse reactions were evaluated.

Antegrade pressure measurement of urinary tract in children with persistent hydronephrosis.

Introduction: Dilation of urinary tract occurs without the presence of obstruction. Diagnostic methods that depend on renal function may elicit mistaken diagnosis. Whitaker (1973) proposed the evaluation of urinary tract pressure submitted to constant flow.

Evaluation of a simple valve mechanism used to stabilize intraabdominal pressure during surgically induced pneumoperitoneum in small animals.

Background: Preventing sudden changes in intraabdominal pressure (IAP) during surgical pneumoperitoneum may reduce adverse events. This study aimed to describe a valve system that stabilizes intraabdominal pressure, minimizing complications of erratic fluctuations in IAP.

Methods: Five male Sprague-Dowley rats were submitted to pneumoperitoneum, with the insufflator set sequentially at 5, 10, and 15 mmHg for each rat.

Labioscrotal island flap in feminizing genitoplasty.

Background/purpose: Stenosis of the vaginal introitus is the most frequent complication after genital reconstruction for ambiguous genitalia associated with congenital adrenal hyperplasia (CAH). With the aim of enlarging the vaginal introitus, the authors present a technical modification of the introitoplasty that uses a bilateral cutaneous island flap based on the perineal superficial branches of the internal pudendal artery.

Methods: Eleven girls with CAH and Prader III to V genital ambiguity were included.
