Simulation in pediatric minimally invasive surgery: adaptation of a simple series of exercises as part of the process of an initial implementation of a resident training program.

Introduction: the simulation in minimally invasive surgery is fundamental for surgeon in training to learning and training skills, especially in pediatrics, due to the particularities, reduced spaces, specific and rare procedures. The aim of this study was to propose an adapted series of exercises and to simply evaluate the performance of pediatric surgery residents in the initial implementation of a training program.

Method: seven basic skills exercises in video surgery, based on series and programs already published and using low-cost materials, were performed by six residents in 2 moments, with an interval of 15 days and evaluated by simple instrument.

Comparative effectiveness of telesimulation versus standard simulation for pediatric Minimally Invasive Surgery (MIS) essential skills training.

Background: Proctored on site simulation-based surgical education has been integrated in our residents curricula since 2012. Due to COVID-19 pandemic and social distance protocols, we developed a Tele-assisted Essential Skills Training Module (T-ESTM). The aim of this study is to evaluate comparative effectiveness between Telesimulation (T) versus Standard Simulation (S) for minimally invasive surgery (MIS) essential skills training.

Primary Malignant Liver Tumors: eight-year experience in a Pediatric Hospital in Brazil. A cross-sectional study.

Introduction: liver tumors are rare neoplasms in childhood (1-2%), and about 2/3 are malignant. Hepatoblastoma (HB) is the most frequent, followed by hepatocellular carcinoma (HCC). In both, the main treatment is surgical resection.

COVID-19 associated multisystem inflammatory syndrome in children mimicking acute appendicitis - how to differentiate and conduct pediatric patients during the pandemic? - Proposal of a management flowchart.

Introduction: the new coronavirus pandemic has been a reality throughout 2020, and it has brought great challenges. The virus predominantly manifests in the pediatric population with mild symptoms. However, an increase in the incidence of Multisystemic Inflammatory Syndrome in Children (MIS-C) associated with COVID-19 has been described in the literature.

Simulation in Pediatric Video Surgery: Training with Simple and Reproducible Exercises Elaborated by Residents.

Most residents do not have a defined program for simulation training in video surgery in Brazil. The training takes place for the most part or in short courses. The goal of this article is to describe and evaluate a set of exercises using low-cost materials, created by the residents themselves, to enable basic skills training in video surgery.

Choledochal cyst in the pediatric population: experience of 13 laparoscopic procedures in two years at a single institution.

Objective: to describe the first 13 cases of laparoscopic correction of common bile duct cyst in the Pequeno Príncipe Hospital, Curitiba, Paraná, Brazil.

Methods: we performed a retrospective analysis of medical records of cases of choledochal cyst operated by laparoscopy between March 2014 and September 2016.

Results: of the 13 patients, eight were female and the mean age at surgery was 7.

Does androgen stimulation prior to hypospadias surgery increase the rate of healing complications? - A preliminary report.

Objective: Androgens have a positive effect on penile growth in children, but they may also have a repressive effect on the healing process. The aim of this prospective study was to compare the outcomes of onlay urethroplasty with and without preoperative androgen stimulation in patients with severe hypospadias.

Patients And Method: Of 300 severe hypospadias cases treated at a single institution, 126 operated on by the same surgeon had complete follow-up data, and 30 of these received preoperative androgen treatment (human chorionic gonadotrophin and/or systemic testosterone) 1-24 months before surgery.

Outcome of severe hypospadias repair using three different techniques.

Objective: To compare the outcomes of three different urethroplasty techniques (onlay, buccal mucosa, Koyanagi type I) used in the reconstruction of severe hypospadias.

Patients And Methods: Over 10 years (1997-2007), 300 severe hypospadias cases were treated with a mean follow up of 2 years (1-105 months); 203 were operated by the same surgeon of whom 184 completed follow up. Three main techniques were used according to the quality of the urethral plate: onlay urethroplasty (133), buccal graft urethroplasty (25) and Koyanagi type I (26).
