Peri-Ulcerative Mucosal Inflammation Appearance is an Independent Risk Factor for 30-Day Rebleeding in Patients with Gastric Ulcer Bleeding: A Multicenter Retrospective Study.

Abstract

AimThe aim of this study was to identify clinical endoscopic indicators related to peri-ulcerative mucosal inflammation and to analyze whether the degree of peri-ulcerative mucosal inflammation appearance is an independent risk factor for gastric ulcer rebleeding.MethodsWe conducted a retrospective study that included patients with gastric ulcer bleeding who were hospitalized at three medical centers in China from January 1, 2016 to December 31, 2019. Ulcer rebleeding that occurred within 30 days of successful initial hemostasis was analyzed to determine whether this event was related to the degree of peri-ulcerative mucosal inflammation appearance or other mucosal inflammation-related factors.ResultsWe enrolled 1111 patients and determined that GBS-Rebleeding-ROC (P<0.001), age (P=0.01), use of NSAIDs (P=0.001), bile reflux (P<0.001), and Helicobacter pylori (P<0.001) are all risk factors for peri-ulcerative mucosal inflammation appearance. Through multivariate analysis, we determined that severe peri-ulcerative mucosal inflammation appearance (P=0.002) was an independent risk factor for ulcer rebleeding within 30 days. Finally, we developed a risk assessment model using factors associated with mucosal inflammation that may be useful for early prediction of rebleeding.ConclusionThe risk factors for peri-ulcerative mucosal inflammation appearance were identified. Severe peri-ulcerative mucosal inflammation appearance is an independent risk factor for ulcer rebleeding.
