Results of Ex-vivo experiments (qualitative and quantitative evaluation). (a) Gaps gradually enlarged due to increased intra-gastric pressure. (b) Uniformly occluded even under increased intragastric pressure. (c) The new clamper showed significantly higher bursting pressure than pinch-type clamper. (46.1 mmHg [37.8–80.8] vs. 13.6 mmHg [11.8–15.4], P < 0.01)
