polidocanol and Shock

Although endoscopic injection therapy is effective in controlling initial haemorrhage from peptic ulcer, between 10% to 30% of patients suffer rebleeding.. To assess the factors that may predict the failure of endoscopic injection in patients bleeding from high risk gastric ulcer.. One hundred and seventy eight patients admitted for a gastric ulcer with a bleeding or a non-bleeding visible vessel were included.. Patients received endoscopic therapy by injection for adrenaline and polidocanol. Twelve clinical and endoscopic variables were entered into a multivariate logistic regression model to ascertain their significance as predictive factor of therapeutic failure.. Eighty seven per cent (155 of 178) of patients had no further bleeding after endoscopic therapy. Endoscopic injection failed in 23 (13%) patients: 20 (12%) continued to bleed or rebleed, and three (1%) patients could not be treated because of inaccessibility of the lesion. Logistic regression analysis showed that therapeutic failure was significantly related to: (1) the presence of hypovolaemic shock (p = 0.09, OR 2.38, 95% CI: 0.86, 6.56), (2) the presence of active bleeding at endoscopy (p = 0.02, OR 2.98, 95% CI: 1.12, 7.91), (3) ulcer location high on the lesser curvature (p = 0.04, OR 2.79, 95% CI: 1.01, 7.69), and (4) ulcer size larger than 2 cm (p = 0.01, OR 3.64, 95% CI: 1.34, 9.89).. These variables may enable identification of those patients bleeding from gastric ulcer who would not benefit from injection therapy.
