Long-Term Results of One-Stage Laparoscopic-Assisted Endorectal Pull-Through for Rectosigmoid Hirschsprung's Disease in Patients Aged Above 5 Years.

Despite the fact that the laparoscopic-assisted endorectal pull-through (LAEPT) for Hirschsprung's disease (HD) was introduced over 20 years ago, published outcomes in older children and adolescent are lacking. To address this, we studied the long-term results of LATEP for rectosigmoid HD in patients above 5 years of age. A retrospective review was conducted on all nonsyndromic patients above 5 years of age and who underwent one-stage LAEPT for rectosigmoid HD between January 2002 and December 2017.

Comparison of Characteristics and Outcomes in Antenatally and Postnatally Detected Choledochal Cyst in Infants and Young Children in a Laparoscopic Surgery Center.

The aim of this study was to compare the characteristics and the outcome between infants and young children with antenatally (AN) and postnatally (PN) detected choledochal cyst (CC) in a laparoscopic surgery center. A retrospective review was conducted for all children who underwent excision of CC and hepaticojejunostomy (HJ) before 36 months of age between October 2004 and October 2019. Thirty-nine children (28 girls and 11 boys) were included in this study.

Impact of Age of Patient and Experience of Surgeon on the Outcome after Kasai Portoenterostomy: Can We Delay the Surgery?

Introduction:  Age of patient and experience of biliary atresia (BA) center are well-known factors associated with early jaundice clearance (EJC) after Kasai portoenterostomy (KPE) in infants with BA. This study focused on the impact of age and surgeon factor on the short-term outcome after KPE within a single center.

Materials And Methods:  Fifty-four consecutive infants (18 boys and 36 girls) who underwent KPE from January 2010 to January 2020 were reviewed.

Ten-Year Native Liver Survival Rate After Laparoscopic and Open Kasai Portoenterostomy for Biliary Atresia.

There are no data reporting the 10-year native liver survival rate after LKP. The study aims to present the 10-year native liver survival rate after LKP and complications in native liver survivors after Kasai portoenterostomy (KP).

Objectives: Evaluating the long-term outcome of the surgical management for intestinal strictures developing after necrotizing enterocolitis (NEC).

Patients And Methods: This is a retrospective study of all patients with an intestinal stricture after completion of conservative management for NEC. They were treated during the eight years period from 1st January 2008 to 31st December 2015.

Laparoscopic management of antenatally detected choledochal cyst: a 10-year review.

Background: The aim of this review was to study the characteristics and the outcome of children who underwent laparoscopic management of the antenatally detected choledochal cyst.

Methods: A retrospective review was conducted for all children who underwent excision of antenatally detected choledochal cyst and hepaticojejunostomy from 2005 to 2015.

Results: Fourteen patients (11 females and 3 males) were included in this study.

Use of laparoscopy as the initial surgical approach of impalpable testes: 10-year experience.

Aim: To review the experience in the management of impalpable testes using laparoscopy as the initial approach and the need for inguinal exploration.

Methods: From January 2004 to June 2014, 339 patients with undescended testes underwent operation in our institute. Fifty patients (15%) had impalpable testes.

Irreducible inguinal hernia in children: how serious is it?

Background/purpose: We evaluated the experience with irreducible inguinal hernias at our institution.

Methods: We reviewed patients with an inguinal hernia operation at our institution between 1st January 2004 and 31st December 2013. Individuals with a failed manual reduction of an incarcerated hernia under sedation by the attending surgeon were included into the study group as irreducible hernia.

Laparoscopic excision of Meckel's diverticulum in children: what is the current evidence?

Complications aroused from Meckel's diverticulum tend to developed in children. Children presented with abdominal pain, intestinal obstruction, intussusception or gastrointestinal bleeding may actually suffered from complicated Meckel's diverticulum. With the advancement of minimally invasive surgery (MIS) in children, the use of laparoscopy in the diagnosis and subsequent laparoscopic excision of Meckel's diverticulum has gained popularity.

Early experience in robotic-assisted laparoscopic bilateral intravesical ureteral reimplantation for vesicoureteral reflux in children.

A high success rate has been reported for laparoscopic intravesical ureteral reimplantation in the management of high-grade vesicoureteral reflux in children. With the introduction of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA, USA), robotic-assisted laparoscopic intravesical ureteral reimplantation may provide additional benefits, particularly in intravesical suturing. We present here our experience in three children, all with high-grade bilateral vesicoureteral reflux, who underwent robotic-assisted laparoscopic intravesical bilateral ureteral reimplantation.
