Table of Contents

Local injection of N-butyl-2-cyanoacrylate has been used successfully for the hemostatic treatment of bleeding gastric varices [1]. Various complications associated with the procedure have been reported [2]. The prevalence of infectious complications could range from 4.3 % to 50 %, and most are transient and uneventful [3]. Because prolonged and persistent septic complications have been rarely reported, the appropriate strategy of management in this situation has become a challenge.

A 70-year-old man and a 61-year-old woman with a history of liver cirrhosis underwent local injection of N-butyl-2-cyanoacrylate for bleeding gastric varices. Prolonged and persistent fever with bacteremia occurred after the procedure despite systemic antibiotic administration for more than 1 month. Initial evaluations to determine the source of sepsis were unremarkable in both patients.

A gallium scan for unknown fever was carried out and revealed a significant hot spot in the upper middle abdomen in the first patient ([Figure 1]) but not in the second. We repeated esophagogastroduodenal endoscopy and endoscopic ultrasonography (EUS) in both patients. The first patient had incomplete obturation of perigastric varices flow ([Figure 2 a]). During the procedure, the injected histoacryl cast fell apart ([Figure 2 b]). Fever subsided dramatically on the same day. In the second patient, we found a soft tissue ball in the gastric varices with blood flow passing through ([Figure 3 a, b]). We injected an additional amount of N-butyl-2-cyanoacrylate to obturate the flow of gastric varices completely ([Figure 3 c]), and then fever subsided.

From our cases, the cause of persistent fever and bacteremia after tissue adhesive injection could be incomplete obliteration of gastric varices with bacterial seeding on the soft tissue or adhesive cast. Gallium scan may be helpful in identifying the injection site as the infectious source, as was the case in our first patient. EUS can be used to evaluate residual blood flow of gastric varices, perigastric collateral, and to identify the possible infectious loci [4]. Repeated and complete obliteration of gastric varices are needed to cure this complication in addition to prolonged antibiotic treatment. Another option could be to wait for spontaneous expulsion of the cast and repair of the tissue defect. Surgical intervention should be delayed if clinical circumstances allow [5].
