About the Lab

Professor In-Kel Ho's research lab specializes in pediatric surgical disorders, with a focus on congenital diaphragmatic hernia, mesenteric venous thrombosis, and biliary tract anomalies such as choledochal cysts. The lab emphasizes multidisciplinary approaches to pediatric aerodigestive disorders and investigates prognostic factors, surgical timing, and innovative techniques like laparoscopic single-port inguinal hernioplasty. Research is primarily clinical and retrospective, with a strong emphasis on improving outcomes through early diagnosis, risk stratification, and evidence-based surgical interventions.

BACKGROUND: This study aimed to determine perinatal risk factors for 30-day mortality of congenital diaphragmatic hernia (CDH) patients and develop a prognostic index to predict 30-day mortality of CDH patients. Identifying risk factors that can prognosticate outcome is critical to obtain the best management practices for patients. METHODS: A retrospective study was performed for patients who were diagnosed with CDH from November 2000 to August 2016. A total of 10 prenatal risk factors and 14 po

Mesenteric venous thrombosis as a complication of appendicitis in an adolescent
Seo Hee Yoon, Mi‐Jung Lee, Se Yong Jung, In Geol Ho, Moon Kyu Kim
SJR Q3MedicineOA

RATIONALE: Mesenteric venous thrombosis is an uncommon but potentially fatal condition that can cause bowel ischemia. It results from a systemic hypercoagulable state or abdominal infection draining into the portal venous system. Several cases regarding portomesenteric venous thrombosis as a complication of appendicitis were reported in adults, but there are far fewer reports in pediatric patients. The mortality rate of the condition is high if untreated, especially in children, reaching up to 5

We share our experience on the implementation of a multidisciplinary aerodigestive program comprising an aerodigestive team (ADT) so as to evaluate its feasibility. We performed a retrospective chart review of the patients discussed at the monthly ADT meetings and analyzed the data. A total of 98 children were referred to the ADT during the study period. The number of cases increased steadily from 3.5 cases per month in 2019 to 8.5 cases per month in 2020. The median age of patients was 34.5 mon

Objective Choledochal cysts are increasingly being diagnosed antenatally. The appropriate time of surgical treatment has the greatest impact on the prognosis of choledochal cyst treatment. The purpose of this study was to compare the clinical outcomes of prenatally diagnosed choledochal cysts in infants according to the surgical treatment timing. Methods We retrospectively reviewed the medical records of infants who underwent surgery for choledochal cysts with antenatal diagnoses. We investigate

Our prospective study supports LSGIH as a simple, safe, and useful technique for pediatric inguinal hernioplasty. This method required only one working port and one camera port. However, further clinical prospective trials, including male patients, should be performed to confirm the long-term safety and effectiveness of LSGIH.

Learning curve of ultrasound-guided percutaneous central venous port placement in children

SJR Q2BMC PediatricsOA

BACKGROUND: Although percutaneous central venous port (CVP) placement can be quickly performed using minimally invasive surgery, short- and long-term complications can occur. Beginner pediatric surgeons must overcome learning curves influencing operative time and complication rates. However, few studies have been conducted on the learning curve of ultrasound-guided percutaneous CVP placement. This study analyzed the progress, results, complications, and learning curve of ultrasound-guided percut
