GOAL: Our study aimed to explore the incidence of bleeding from ulcers due to premature band slippage and to identify possible associated factors.
BACKGROUND: Band ligation (BL) plays a vital role in treating esophageal varices; however, the procedure carries a considerable risk of band slippage, variceal site ulcer formation, and posttreatment bleeding.
MATERIALS AND METHODS: We retrospectively reviewed the records of patients with esophageal varices who underwent endoscopic hemostasis by BL at our institution between 2015 and 2020. We statistically compared the patients with post-BL ulcer bleeding and those without (controls). The outcome variable was the development of BL-induced ulcer bleeding. The patients' demographics, clinical, and laboratory parameters, and BL procedure parameters were independent variables. Univariate followed by a multivariate logistic regression were performed to identify possible associated factors from the odds ratio (OR).
RESULTS: Of the 4579 eligible patients, 388 (8.5%) presented with post-BL ulcer bleeding. The presence of high-risk stigmata indicated a 1.271 times higher risk of bleeding [95% confidence interval (CI):1.018-1.587], and a greater number of varices was associated with an increased risk of post-BL ulcer bleeding [OR=1.184 (95% CI: 1.073-1.307)]. Conversely, the use of fewer bands per variceal site was associated with fewer bleeding incidents [OR=1.308 (95% CI: 1.090-1.569)]. Univariate analysis identified proton pump inhibitor as protective [OR=0.770 (95% CI: 0.603-0.983)]; however, the difference was not significant after multivariate analysis [OR=1.283 (95% CI: 1.003-1.640)].
CONCLUSIONS: The overall incidence of post-BL ulcer bleeding was 8.5%. The presence of high-risk stigmata, higher number of varices, and bands per variceal site were associated with an increased risk of post-BL bleeding. The effect of adjuvant proton pump inhibitors was not statistically significant.
