title: Improvement of tissue-adhesive obliteration of bleeding gastric varices using adjuvant hypertonic glucose injection: a prospective randomized trial.
abstract: OBJECTIVE
  Rebleeding can occur after endoscopic injection of gastric varices with tissue adhesive. The aim of this study was to evaluate whether adjuvant hypertonic glucose solution injections enhance the effects of Histoacryl after successful initial variceal obliteration.
  
  
  METHODS
  A total of 67 patients (37 men, 30 women; mean age +/- standard deviation [SD] 60 +/- 17 years) with initially successful Histoacryl obliteration of bleeding gastric varices were included in the study and randomly divided into two groups: a "combined" group of patients who had adjuvant injection of hypertonic glucose solutions in cases of residual gastric varices (F1 or less) and a "control" group of patients who did not receive such therapy. End points were either variceal recurrence/progression (F2 or more) requiring Histoacryl reinjection or rebleeding.
  
  
  RESULTS
  Residual small varices were found in 56% of patients in the combined group and in 60% of patients in the control group. Adjuvant therapy was only performed in the combined group. During the follow-up period (mean duration +/- SD 37.9 +/- 18.5 months, range 19-56 months), two patients in the combined group showed gastric variceal progression, compared with nine patients showing progression in the control group, with two cases of rebleeding, both occurring in the control group. Two years after the first Histoacryl injection, the cumulative proportion of patients who did not have gastric variceal progression was significantly higher in the combined group than it was in the control group (92.8% vs. 71.4%, P = 0.029). There was no significant difference between the two groups with respect to their survival curves (P = 0.12). No marked immediate or delayed symptoms or complications were observed in the patients given hypertonic glucose injections.
  
  
  CONCLUSIONS
  Adjuvant treatment with hypertonic glucose solution for residual small gastric varices is a safe and simple method. It helps reduce the recurrence or progression of gastric varices after tissue adhesive injections and can therefore reduce the risk of rebleeding.
