Abstract
BACKGROUND
there is controversy about the need to maintain vasoconstrictor treatment after adequate haemostasis is achieved through endoscopic band ligation (EBL) in bleeding esophageal varices (BEV). Measuring a "before and after urgent-EBL" hepatic venous pressure gradient (HVPG) in acute variceal hemorrhage is very difficult. Thus, the goal of this study was to determine hemodynamic variations after an EBL session. A "before" HVPG (PRE) was performed and another one 24 hours "after-ligation" (POST), in cirrhotic patients undergoing endoscopic band ligation as BEV prophylaxis.
PATIENTS AND METHODS
this was a single-center, cohort, prospective study. Patients followed a program of repeated sessions of EBL until eradication of their varices and underwent a basal hepatic venous pressure gradient (PRE HVPG), without changing their usual treatment with beta-blockers. Subsequently, an endoscopic ligation session was performed, following the clinical practices guidelines. A second pressure measurement (POST HVPG) was taken 24 hours after the endoscopic treatment.
RESULTS
30 patients were included. PRE and POST HVPG median results were 16.5 mmHg (14-20) and 19.5 mmHg (17-21), respectively, with a significant increase after the procedure (p < 0.001). Percentage variations in portal pressure, based on the baseline gradient values (12, 16 and 20 mmHg), were higher for patients with a lower basal HVPG versus a higher HVPG for any of the categories compared (p = 0.087, p = 0.016 and p < 0.001, respectively). In our series, 36.7 % of patients showed a ≥ 20 % gradient increase after ligation.
CONCLUSION
endoscopic band ligation causes an increase in portal pressure, at least for a transitional period, determined by the hepatic venous pressure gradient.
