title: EUS-guided injection of cyanoacrylate in perforating feeding veins in gastric varices: results in 5 cases.
abstract: BACKGROUND
  Bleeding from gastric varices can be challenging because of its high mortality and recurrent bleeding rates. Endoscopic therapy with tissue adhesives can control acute hemorrhage, but recurrent bleeding could appear if obliteration is not achieved, and endoscopic vision could be troublesome in the case of massive hemorrhage. The glue injected could be responsible for embolic phenomena and local complications. EUS has proved useful in minimizing the risk of recurrent bleeding from gastric varices, accurately showing if they are obturated or not. The presence of perforating veins detected by EUS has been reported as a risk factor for recurrent bleeding from esophageal varices.
  
  
  OBJECTIVE
  To assess the efficacy of EUS-guided cyanoacrylate injection in gastric varices at the entrance of the perforating veins to obtain variceal obturation.
  
  
  METHODS
  Open-basis case series study.
  
  
  METHODS
  Tertiary care, academic medical center, Seville, Spain.
  
  
  METHODS
  Five consecutive patients with gastric varices were enrolled from May 2005 through May 2006.
  
  
  METHODS
  We injected cyanoacrylate-lipiodol in gastric varices with 22-gauge needles by EUS guidance.
  
  
  METHODS
  To analyze the obliteration of gastric varices, the recurrent bleeding rate, and safety of EUS-guided cyanoacrylate-lipiodol injection.
  
  
  RESULTS
  EUS-guided injection of the perforating veins by using cyanoacrylate-lipiodol was successful in eradicating gastric varices in the 5 patients treated, without recurrent bleeding or other complications during the study follow-up.
  
  
  CONCLUSIONS
  This is a single-center nonrandomized study.
  
  
  CONCLUSIONS
  EUS-guided injection of cyanoacrylate at the level of the perforating veins in the treatment of gastric varices seems to be a safe, efficient, and accurate approach. Further controlled studies are warranted.
