Machine-learning-assisted Preoperative Prediction of Pediatric Appendicitis Severity.

Purpose: This study evaluates the effectiveness of machine learning (ML) algorithms for improving the preoperative diagnosis of acute appendicitis in children, focusing on the accurate prediction of the severity of disease.

Methods: An anonymized clinical and operative dataset was retrieved from the medical records of children undergoing emergency appendectomy between 2014 and 2021. We developed an ML pipeline that pre-processed the dataset and developed algorithms to predict 5 appendicitis grades (1 - non-perforated, 2 - localized perforation, 3 - abscess, 4 - generalized peritonitis, and 5 - generalized peritonitis with abscess).

The Canadian Experience With Magnetic Esophageal Anastomosis: A Report From the Canadian Consortium for Research in Pediatric Surgery Study (CanCORPS).

Objective: Magnetic anastomosis is an innovative technique for establishing esophageal continuity in infants born with esophageal atresia. Few case series featuring this technology have been published, with even fewer reports on complications. We present the entire Canadian experience with this approach.

STAT trial: stoma or intestinal anastomosis for necrotizing enterocolitis: a multicentre randomized controlled trial.

Purpose: The STAT trial is a multicenter randomized controlled trial in 12 centers worldwide aiming to determine the most effective operation for neonates with necrotizing enterocolitis (NEC) requiring intestinal resection: stoma formation (ST) or primary anastomosis (PA).

Methods: Infants having a primary laparotomy for NEC were randomized intraoperatively to PA or ST if the operating surgeon thought that both were viable treatment options for that patient. The primary outcome (duration of parenteral nutrition [PN]) was evaluated by Cox regression.

GAPS phase II: development and pilot results of the global assessment in pediatric surgery, an evidence-based pediatric surgical capacity assessment tool for low-resource settings.

Purpose: Pediatric surgical care in low- and middle-income countries is often hindered by systemic gaps in healthcare resources, infrastructure, training, and organization. This study aims to develop and validate the Global Assessment of Pediatric Surgery (GAPS) to appraise pediatric surgical capacity and discriminate between levels of care across diverse healthcare settings.

Methods: The GAPS Version 1 was constructed through a synthesis of existing assessment tools and expert panel consultation.

A minimally invasive hybrid procedure to correct pectus arcuatum.

Background: Pectus arcuatum, also known as horns of steer anomaly or Currarino-Silverman Syndrome, is a distinct chest wall anomaly characterized by severe manubriosternal angulation, a shortened sternum, and mild pectus excavatum. The anomaly is typically repaired using open techniques, employing orthopedic fixation devices. Here, we report the results of a minimally invasive hybrid procedure to repair pectus arcuatum.

The Canadian Pediatric Surgery Workforce: A 10-year Prospective Assessment.

Background: The Canadian Association of Paediatric Surgeons launched a 10-year prospective assessment of the Canadian pediatric surgery workforce and training environment, beginning in 2013. The results of the first 5 years (2013-2017) were previously published. Here, we present the results of the last 5 years (2018-2022), and the cumulative results of the past decade.

Using Artificial Intelligence to Label Free-Text Operative and Ultrasound Reports for Grading Pediatric Appendicitis.

Purpose: Data science approaches personalizing pediatric appendicitis management are hampered by small datasets and unstructured electronic medical records (EMR). Artificial intelligence (AI) chatbots based on large language models can structure free-text EMR data. We compare data extraction quality between ChatGPT-4 and human data collectors.

James Warden and the Global Alliance Partnership: A Pediatric Surgery Giant and His Enduring PAPS Landmark.

The discipline of pediatric surgery has honored many of the early giants through programs that bear their names. One of those programs is the M. James Warden Global Alliance Partnership, a landmark program celebrated at each annual meeting of the Pacific Association of Pediatric Surgeons since 1989.

Open and laparoscopic inguinal hernia repair in children: A regional experience.

Purpose: The optimal approach for pediatric inguinal hernia repair continues to be debated. We conducted a regional retrospective study to assess rates of recurrence and metachronous hernias after open repair (OPEN) and laparoscopic repair (LAP) METHODS: A retrospective cohort study was conducted at two children's hospitals that serve a region of approximately 4 million people. All patients < 14 years old undergoing OPEN or LAP by pediatric surgeons during a 5-year period (2011 - 2015) were analyzed after a minimum follow up of 4 years.

"Your child needs surgery": A survey-based evaluation of simulated expert consent conversations by key stakeholders.

Background: Consent conversations in pediatric surgery are essential components of pre-operative care which, when inadequate, can lead to significant adverse consequences for the child, parents, surgeon, and others in the healthcare system. The aim of this study is to explore expert consenting practice from the key stakeholders' perspective.

Methods: Four senior attending pediatric surgeons obtained consent from a standardized mother of a child requiring surgery in two scenarios: a low-risk elective surgery (inguinal hernia repair - Video 1), and a high-risk emergency surgery (intestinal atresia - Video 2).

Patient experience or patient satisfaction? A systematic review of child- and family-reported experience measures in pediatric surgery.

Purpose: Patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) are increasingly recognized as important health care quality indicators. PREMs measure patients' perception of the care they have received, differing from satisfaction ratings, which measure their expectations. The use of PREMs in pediatric surgery is limited, prompting this systematic review to assess their characteristics and identify areas for improvement.

The Canadian Consortium for Research in Pediatric Surgery: Roadmap for Creation and Implementation of a National Subspecialty Research Consortium.

Clinical practice should be driven by high-quality research that produces evidence to inform best practices. Generation of such evidence is often challenging, particularly for smaller specialties, such as pediatric surgery, that treat many patients with rare diseases. Multi-institutional collaboration is seen as a major strategy to address these challenges.

Gastroschisis prognostic score successfully identifies Brazilian newborns with high-risk gastroschisis.

Background: The Gastroschisis Prognostic Score (GPS) stratifies patients as high or low risk based on the visual assessment of intestinal matting, atresia, perforation, or necrosis. Despite being a simple score, its applicability to low and middle-income countries (LMICs) remains unknown. We tested the hypothesis that GPS can predict outcomes in LMICs, by assessing the prognostic value of the GPS in a middle-income country.

Treatment and Outcomes of Congenital Ovarian Cysts A Study by the Canadian Consortium for Research in Pediatric Surgery (CanCORPS).

Objective: We conducted a multicenter study to assess treatments and outcomes in a national cohort of infants with congenital ovarian cysts.

Summary Background Data: Wide variability exists in the treatment of congenital ovarian cysts. The effects of various treatment strategies on outcomes, specifically ovarian preservation, are not known.

Patient-reported outcome measures in pediatric surgery - A systematic review.

Purpose: With improved long-term survival rates, measuring the quality of surgical care has gradually shifted from clinical morbidity and mortality to patient-reported outcome measures (PROMs). Since the use of PROMs in pediatric surgery is still limited, we undertook a study to identify current PROMs, assess their characteristics, and identify gaps and areas for improvement.

Methods: A search was conducted in eight databases from their inception until May 2021 to identify PROMs that have been used in pediatric surgical patients.

Egyptian expert opinion for the use of sodium-glucose cotransporter-2 inhibitors in patients with heart failure with reduced ejection fraction.

Sodium-glucose cotransporter-2 inhibitor (SGLT2i) in patients with type 2 diabetes reduces the risk of serious heart failure events, specifically the risk of hospitalization for heart failure, and cardiovascular death. The benefit is most apparent in patients with a heart failure with reduced ejection fraction (HFrEF). Dapagliflozin and empagliflozin reduced the risk of cardiovascular death and hospitalizations for heart failure in patients with established HFrEF, including those without diabetes.

Postoperative pain following minimally invasive repair of pectus excavatum: A descriptive study.

Background: Minimally Invasive Repair of Pectus Excavatum (MIRPE) is associated with significant postoperative pain. The objective of our study was to characterize the severity and duration of this pain, and to investigate possible associations with pectus severity.

Methods: We conducted a retrospective cohort study of pediatric patients who underwent MIRPE from January 2014 to April 2018.

Differentiating congenital ovarian cysts from other abdominal cystic lesions in female infants: A study by the Canadian Consortium for Research in Pediatric Surgery (CanCORPS).

Purpose: The origin of congenital abdominal cysts in the female fetus often dictates management. While most arise from the ovary and are often managed non-operatively, some are non-ovarian and are frequently removed. We analyzed a national sample of female infants with congenital abdominal cysts to elucidate prenatal and postnatal factors associated with the diagnosis of a non-ovarian cyst.

Use of a risk communication survey to prioritize family-valued outcomes and communication preferences for children undergoing outpatient surgical procedures.

Background: Effective shared decision-making in pediatric surgery requires clarity regarding which surgical outcomes are most important to patients and their families, and how they prefer to receive the information. Despite how essential this is for effective risk communication, little is known about the communication needs and preferences of patients and their families in elective pediatric surgery.

Methods: We administered a mailed and online cross-sectional survey in English and French to 548 families before or after surgery for hernia/hydrocele repair or tonsillectomy/adenoidectomy between July 2019 and February 2021.

The utility of echocardiography and pulmonary function testing in the preoperative evaluation of pectus excavatum.

Purpose: Echocardiography (ECHO) and pulmonary function testing (PFT) are routinely performed during the preoperative evaluation of pectus excavatum (PE). We hypothesized that these investigations may be performed selectively based on patient symptoms and pectus severity.

Methods: A retrospective review of all PE patients who underwent a Nuss procedure during a 15-year period (2004-2018) was conducted.
