摘要
AIM: To clarify the efficacy of proton pump inhibitors (PPIs) after endoscopic variceal obturation (EVO) with N-butyl-2-cyanoacrylate. %26lt;br%26gt;METHODS: A retrospective study was performed on 16 liver cirrhosis patients with gastric variceal bleeding that received EVO with injections of N-butyl-2-cyanoacrylate at a single center (Kyung Hee University Hospital at Gangdong) from January 2008 to December 2012. Medical records including patient characteristics and endoscopic findings were reviewed. Treatment results, liver function, serum biochemistry and cirrhosis etiology were compared between patients receiving PPIs and those that did not. Furthermore, the rebleeding interval was compared between patients that received PPI treatment after EVO and those who did not. %26lt;br%26gt;RESULTS: The patient group included nine males and seven females with a mean age of 61.8 +/- 11.7 years. Following the EVO procedure, eight of the 12 patients that received PPIs and three of the four non-PPI patients experienced rebleeding. There were no differences between the groups in serum biochemistry or patient characteristics. The rebleeding rate was not significantly different between the groups, however, patients receiving PPIs had a significantly longer rebleeding interval compared to non-PPI patients (22.2 +/- 11.2 mo vs 8.5 +/- 5.5 mo; P = 0.008). The duration of PPI use was not related to the rebleeding interval. A total of six patients, who had ulcers at the injection site, exhibited a shorter rebleeding interval (16.8 +/- 5.9 mo) than patients without ulcers (19.9 +/- 3.2 mo), though this difference was not statistically significant. %26lt;br%26gt;CONCLUSION: PPI therapy can extend the rebleeding interval, and should therefore be considered after EVO treatment for gastric varices.
