Introduction: Gastric varices are frequently seen in patients with portal hypertension. The mainstay of treatment is variceal injection with a mixture of N-butyl-2-Cyanoacrylate and lipiodol. The use of N-butyl-2-Cyanoacrylate without lipiodol is not extensively studied and it can be a cost-effective approach. The objective of our study was to evaluate whether the use of N-butyl-2-Cyanoacrylate without lipiodol is a safe and effective endoscopic treatment for gastric varices.
Material and Methods: This prospective observational study was conducted between June 2016 and May 2017 at the Department of Gastroenterology, Gujranwala Medical College/ DHQ Teaching Hospital, Gujranwala. A total of 100 patients with gastric varices diagnosed on upper GI endoscopy were enrolled in the study. N-butyl-2-Cyanoacrylate without lipiodol was injected into the gastric varices of all the patients. All procedures were performed by experienced gastroenterologists. The patients underwent monthly follow-up endoscopies to determine the outcome and adverse events.
Results: Out of 100 patients, 40 patients (40 %) were men and 60 (60%) were women. The mean age was 53 years. The mean volume of N-butyl-2-Cyanoacrylate used per session was 1.5ml ± 0.5 ml (range 1-2ml). Obliteration of Gastric varices was achieved in 92 patients (92%) while in 04 patients (4%) varices did not obliterate over a mean follow-up of 12 months. No treatment-related immediate or late complications were observed in all patients. Four patients (4%) died of delayed rebleeding (after two weeks of intervention).
Conclusion: Injection therapy of gastric varices with N-butyl-2-Cyanoacrylate alone without lipiodol is a safe and cost-effective method for gastric varices.
