Abstract
AIM
To evaluate retrospectively the incidence and predictors of massive bleeding after stent placement for malignant oesophageal stricture/fistulae.
MATERIALS AND METHODS
This retrospective study comprised 519 patients with malignant oesophageal stricture/fistulae that were successfully treated with stent placement at three hospitals. The patients were divided into two groups based on the occurrence of massive bleeding. Univariate and multivariate analysis was performed to evaluate predictive factors of massive bleeding.
RESULTS
Massive bleeding occurred in 54 of 519 patients 1-37 days following stent placement. All of the patients who developed massive bleeding died within 24 hours of the event. Univariate analysis showed massive bleeding was associated with the presence of a concomitant tracheal stent (p<0.001), the existence of concomitant oesophageal fistulae (p<0.001), and prior radiotherapy (p<0.001). Multivariate analysis exhibited that concomitant tracheal stent insertion (odds ratio [OR], 23.134; 95% confidence interval [CI], 9.523-56.199; p<0.001), the presence of oesophageal fistulae (OR, 3.724; 95% CI, 1.677-8.269; p=0.001), and prior radiotherapy (OR, 13.310; 95% CI, 5.464-32.421; p<0.001) were predictors of massive bleeding following stenting.
CONCLUSIONS
The presence of oesophageal fistulae, prior radiotherapy, and concomitant tracheal stent are important factors contributing to bleeding after stenting.
