Aim:
To explore the effect of in vitro porcine esophageal variceal pressure on complete ligation degree for polycyclic ligators.
Methods:
An in vitro model of experimental porcine venous vessels was used to test various venous pressures. Three treatment groups were designated according to the preset pressure range: P1 = 25-30 cmH₂O; P₂ = 35-40 cmH₂O; P₃ = 45-50 cmH2O. The effect of pressure on ligation was assessed and compared among the groups.
Results:
Complete ligation was achieved at a rate of 56.25% (18/32) in group P1, 37.5% (12/32) in group P₂, and 33.33% (11/33) in group P₃ (χ (2) = 3.6126; P = 0.0573).
Conclusion:
Higher variceal pressures impair the ligation completion rate. Therefore, measuring variceal pressure may help predict the effect of endoscopic ligation and guide treatment choice.
