BACKGROUND AND STUDY AIMS: Recently, details of a noninvasive balloon manometry technique for endoscopic measurement of @entity551 ( @entity551 ) have been published. However, to date, only few data exist on its feasibility and virtually none on its relation to endoscopic or clinical variables of @entity101 . @entity1 AND METHODS: We investigated a total of 64 @entity1 with esophageal varices using a scaled transparent balloon and a calibrated pressure manometer. Averaged from both fivefold balloon insufflation (variceal collapse) or desufflation (variceal appearance), we took measurements of the @entity551 (mmHg) using the two techniques. These measurements were correlated between two investigators as well as to both clinical and endoscopic signs of @entity101 . Furthermore, pressures were assessed prospectively before and during @entity1169 application. RESULTS: Measurements were successful in > 95% of all sessions without side effects. The intraobserver variance was 11.0 +/- 13.1%. Measurements correlated significantly between two observers (r = 0.80, insufflation technique, p < 0.01/r = 0.81, desufflation technique, p < 0.01). Pressures correlated positively to variceal sizes (p < 0.05). The presence of fundic varices was strongly associated with higher pressures (p < 0.02). In @entity1 without medical decompressive therapy we found a significant relationship between @entity551 and the presence of red colour signs or previous @entity548 episodes. Clinical parameters did not correlate with @entity551 (p > 0.05). As assessed by this technique, 8/11 @entity1 receiving @entity1169 showed a decrease in @entity551 (18.6 +/- 19.5% after 1.5 months and 33.3 +/- 11.9% after 3 months). CONCLUSIONS: This noninvasive balloon technique is a safe and practical method for estimating @entity551 in @entity1 with @entity101 . As found by invasive methods, @entity1 with large varices and concomitant fundic varices have higher @entity551 . A drop in intravariceal pressure after @entity1169 therapy appears to be assessable.
