Abstract:
BACKGROUND/AIMS: As the elderly population taking antithrombotic therapy (ATT) increases, gastrointestinal (GI) bleeding risk during ATT may likely increase. This study was conducted to evaluate the clinical characteristics of severe upper GI bleeding (UGIB) during ATT. MATERIALS AND METHODS: Among patients on ATT at Gyeongsang National University Hospital between March 2005 and February 2010, those with severe UGIB requiring endoscopic hemostasis were selected for the study. Their medical records were retrospectively reviewed for clinical variables. RESULTS: Among 59,773 patients taking ATT, 125 (0.21%) developed severe UGIB and comprised 12.8% of the overall endoscopic hemostasis cases (125/978) during the same period. The patients with severe UGIB on ATT were older than the ones not on ATT (68.3 vs. 59.9 years, P<0.001). The common indications for ATT were cardiovascular (60.8%, 76/125) and cerebrovascular diseases (25.6%, 32/125). Fifty-nine patients (47.2%) were taking two or more agents, 36 (28.8%) were on aspirin monotherapy, while 22 (17.6%) were taking warfarin alone. Aspirin was involved in 68.8% (86/125) of severe UGIB. According to ATT type, the incidence of severe UGIB was 0.48% with warfarin, 0.38% with aspirin, and 0.33% with clopidogrel. The main causes of severe UGIB were gastric (78, 62.4%) and duodenal ulcers (15, 12.0%). UGIB recurred in 11 cases (8.8%), but all were successfully controlled with repeated hemostasis and there was no mortality. CONCLUSIONS: The frequency of severe UGIB during ATT was 0.21%. Aspirin was the most common agent leading to severe UGIB, but its incidence was highest with warfarin. Gastric ulcer was the most common focus. Endoscopic hemostasis was effective and safe for UGIB during ATT.
