Safety of endoscopic N-Butyl-2 Cyanoacrylate injection for the treatment of bleeding gastric varices in children

摘要

Objective: To determine the safety and efficacy of N-butyl 2-cyanoacrylate in bleeding gastric varices in children. Methods: This retrospective observational study was conducted in the Department of Gastroenterology and Pediatric Surgery in Liaquat National Hospital Karachi between January 2010 and January 2017. Gastric fundal varices were obliterated in pediatric population with single shot of N-butyl-2 Cyanoacrylate 0.50ml diluted with 0.50ml of Lipoidal with use of forward-viewing video endoscope with 22-gauge needle. The primary outcome was primary hemostasis, Secondary outcome was complications, re-bleeding and mortality. Results: Thirty patients was included in the study, 18(60%) were male with mean age of 7.12± 2.9 years. Non cirrhotic portal hypertension was the most common etiology in 15(50%) patients, followed by liver cirrhosis secondary to hepatitis B and D co-infection in 6(20%) patients. Primary hemostasis was achieved in 29 (96.7%), while 3(10%) patients developed rebleeding after 48 hours, and hemostasis was achieved after second session of endoscopic obliteration. Abdominal pain and fever developed in 3(10%) patients which was managed conservatively. Mortality was observed in 1(3%) of cases due to sepsis after shunt surgery. Conclusion: Endoscopic fundal varix obliteration with N Butyl-2 cyanoacrylate was safe and effective in treatment of gastric variceal hemorrhage in children.
