In order to assess the presence and the severity of upper
GI bleeding in these patients, relevant clinical findings and
laboratory data were gathered and documented. Once the
clinical diagnosis of upper GI bleeding was established,
the endoscopic examination was employed to confirm the
presence of the gastrointestinal mucosal lesions and the
etiology. The timeframe in which endoscopic examination
was performed ranged from 15 minutes to 12 hours after
the clinical diagnosis of upper GI bleeding. This represented
