Purpose: Pediatric gastrointestinal (GI) endoscopy significantly contributes to the diagnosis and management of GI diseases in children. Global data on pediatric GI endoscopy in the Asia-Pacific region are limited. We aimed to report the findings of a regional survey on pediatric endoscopy in the Asia-Pacific region. Methods: A questionnaire-based survey involving GI endoscopy centers in 13 Asia-Pacific countries (June to November 2021). The questionnaires included annual procedure volumes (from basic diagnostics to advanced therapeutic endoscopy), endoscopists, sedation procedures, and national training programs. Results: A total of 162 GI endoscopy centers completed the survey. All centers performed basic endoscopies (esophagogastroduodenoscopy and ileocolonoscopy); however, 45.1% and 59.1% of the centers performed less than 50 esophagogastroduodenoscopies and ileocolonoscopies per year, respectively. Small bowel evaluation (capsule endoscopy or balloon-assisted enteroscopy) was performed in 59.3% of the centers. Foreign body removal, polypectomy, and percutaneous endoscopic gastrostomy were performed in 89.5%, 85.8%, and 52.5% of centers, respectively. Endoscopic hemostatic interventions, which are lifesaving procedures, included glue injection (30.9%), hemostasis of nonvariceal bleeding (65.4%), and endoscopic variceal ligation (70.4%). Pediatric GI endoscopy is performed not only by pediatric gastroenterologists but also by adult gastroenterologists in 21–50% of centers for many kinds of procedures. Sedation was provided by anesthesiologists in 65.4% of the centers. Most centers offer both adult and pediatric endoscopy training. Conclusion The study highlights regional disparities in pediatric GI endoscopy services. It emphasizes the need for expanded pediatric GI training and improved access to therapeutic endoscopy, particularly for life-saving procedures.

Replacement of the retrohepatic inferior vena cava (IVC) after concurrent resection of IVC and tumor-bearing liver is regarded as a feasible living donor liver transplantation (LDLT) technique to cope with tumors around the IVC. This method can make the resection extent of LDLT comparable to that of deceased-donor liver transplantation. We present one pediatric LDLT case with IVC replacement using an enlarged iliac vein conduit to treat advanced hepatoblastoma. The patient was a 33-monthold and 12 kg-weighing girl suffering from large multiple hepatoblastomas invading the retrohepatic IVC. At 2-month waiting after deciding LDLT, we obtained a coldstored iliac vein graft and LDLT was performed with the father’s left lateral section graft. A 1.3 cm-wide and 10 cm-long iliac vein was transformed to be a 2 cm-wide and 5 cm-long vein graft through a double-barrel unification venoplasty. The left lateral section graft was implanted along the standard procedure of LDLT. The patient recovered uneventfully and is undergoing scheduled adjuvant chemotherapy. IVC replacement with vein homograft is a feasible option for LDLT in pediatric patients with advanced liver malignancy.

Background: We aimed to investigate the characteristics of pediatric ulcerative colitis (UC) at diagnosis in Korea. Methods: This was a multicenter, registry-based, inception cohort study conducted in Korea between 2021 and 2023. Children and adolescents newly diagnosed with UC < 18 years were included. Baseline clinicodemographics, results from laboratory, endoscopic exams, and Paris classification factors were collected, and associations between factors at diagnosis were investigated. Results: A total 205 patients with UC were included. Male-to-female ratio was 1.59:1, and the median age at diagnosis was 14.7 years (interquartile range 11.9–16.2). Disease extent of E1 comprised 12.2% (25/205), E2 24.9% (51/205), E3 11.2% (23/205), and E4 51.7% (106/205) of the patients. S1 comprised 13.7% (28/205) of the patients. The proportion of patients with a disease severity of S1 was significantly higher in patients with E4 compared to the other groups (E1: 0% vs. E2: 2% vs. E3: 0% vs. E4: 24.5%, P < 0.001). Significant differences between disease extent groups were also observed in Pediatric Ulcerative Colitis Activity Index (median 25 vs. 35 vs. 40 vs. 45, respectively, P < 0.001), hemoglobin (median 13.5 vs.13.2 vs. 11.6 vs. 11.4 g/dL, respectively, P < 0.001), platelet count (median 301 vs. 324 vs. 372 vs. 377 × 103 /μL, respectively, P = 0.001), C-reactive protein (median 0.05 vs. 0.10 vs. 0.17 vs. 0.38 mg/dL, respectively, P < 0.001), and Ulcerative Colitis Endoscopic Index of Severity (median 4 vs. 4 vs. 4 vs. 5, respectively, P = 0.006). No significant differences were observed in factors between groups divided according to sex and diagnosis age. Conclusion This study represents the largest multicenter pediatric inflammatory bowel disease cohort in Korea. Disease severity was associated with disease extent in pediatric patients with UC at diagnosis.
