The usefulness of prevention consolidation therapy of esophageal varices using an argon plasma coagulation technique

Abstract

Background and study aim: esophageal variceal ligation (EVL) has been spread widely as a simple and effective method for treating esophageal varices. However, in view of the unacceptably high rate of recurrence associated with this technique, the availability of other supplemental consolidation therapies has been earnestly desired. Under these circumstances, attempts such as endoscopic injection sclerotherapy (EIS) have been made for this particular therapeutic purpose. In the current study, we tested the clinical usefulness and safety of the argon plasma coagulation technique (APC). Patients and methods: 11 patients with imminent signs of esophageal varix rupture in our hospital were subjects in the present study. Before APC was performed, these patients underwent EVL with consequent improvement of esophageal varices from F3 (largest sized varices) to disappear or F1 (straight). Results: the patients were followed up for a mean post-treatment period of 637.4 (SD ±56.5) days, and no obvious recurrence of varices in the so-called critical area was noted. In addition, no serious complications were observed. Conclusion: our current clinical study has demonstrated that APC may be an effective prevention consolidation therapy after EVL without serious complications.
