Insights
Argon plasma coagulation (APC) is effective for pediatric endoscopy, successfully treating bleeding lesions and granulomatous tissue in children. This minimally invasive technique demonstrated efficacy with a low complication rate in the studied pediatric population.
Area of Science:
- Gastroenterology
- Pediatric Endoscopy
- Minimally Invasive Procedures
Background:
- Argon plasma coagulation (APC) presents potential benefits for pediatric endoscopic interventions.
- Pediatric patients often have complex medical histories requiring specialized treatment approaches.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic argon plasma coagulation (APC) in pediatric patients.
- To assess APC's utility in managing bleeding lesions and other tissue abnormalities in children.
Main Methods:
- Argon plasma coagulation (APC) was performed on 13 pediatric patients (0.05-17 years) with significant comorbidities.
- Procedures addressed bleeding lesions in the stomach, duodenum, and enterocolonic anastomosis, as well as esophageal granulomatous tissue.
- A total of 23 procedures were conducted, with 22 targeting bleeding.
Main Results:
- Hemostasis was achieved in 8 of 12 patients with bleeding lesions after a single APC session.
- Reduced blood loss and transfusion requirements were observed in 3 of 4 remaining patients.
- Complete eradication of granulomatous tissue was achieved in 2 of 3 cases; complications occurred in 2 patients (submucosal gas, scar formation).
Conclusions:
- Endoscopic argon plasma coagulation (APC) is an efficacious treatment for achieving hemostasis and performing tissue ablation in pediatric patients.
- The procedure demonstrated a low rate of minor complications (17%) in this series of pediatric cases.
Background:
Argon plasma coagulation has potential advantages in pediatric endoscopy.
Methods:
Argon plasma coagulation was applied in 13 children (age 0.05-17 years; median 3 years) with significant comorbid conditions including immunosuppression, chemotherapy, acute or chronic organ failure, and coagulopathy. Twelve had bleeding lesions; esophageal granulomatous tissue was coagulated in one. The bleeding lesion was located in the stomach in 9 of 12, the duodenum in 2 of 12 (both with granulomatous tissue), and at an enterocolonic anastomosis in 1 of 12.
Observations:
In total, 23 procedures were performed, 22 for bleeding (range 1-5 per patient). Hemostasis was achieved in 8 of 12 with one session. Blood loss and transfusion requirement were reduced in 3 of the other 4 patients. Blood loss was not affected in 1. Bleeding recurred in 3 of 12, and additional procedures were performed in 7 of 12. Granulomatous tissue was completely eradicated in 2 of 3; in one, granulomatous tissue associated with surgical staples was only partially removed. Complications occurred in 2 of 13 patients and included submucosal argon gas and scar formation.
Conclusion:
Endoscopic argon plasma coagulation is efficacious for hemostasis and tissue ablation in pediatric patients. Minor complications occurred in 17% (2/13) of cases in this series.
