Abstract:
Objective:To analyze the diagnostic value of bedside capsule endoscopy in patients with acute or severe gastrointestinal bleeding.Methods:Clinical data from patients who underwent bedside capsule endoscopy due to acute or severe suspected gastrointestinal bleeding in Nanfang Hospital, Southern Medical University from June 2018 to September 2021 were analyzed retrospectively. The efficacy of capsule endoscopy in detecting upper gastrointestinal tract and small intestinal bleeding was evaluated.Results:A total of 74 patients underwent bedside capsule endoscopy for suspected acute or severe gastrointestinal bleeding. Five patients were excluded due to failure of examination due to retention of capsule endoscope in the gastric lumen, and 69 were included in the study, of whom 54 patients with a definitive diagnosis of gastrointestinal hemorrhage. The positive detection rate of the capsule endoscopy was 83.33% (45/54), including 17 cases of ulcer, 5 cases of erosion, 5 cases of vascular malformation, 4 protrusion mass, 4 diverticulum, 5 obscure gastrointestinal bleeding, 1 stenosis , 1 active mucosal blood exudation, 1 gastric retention, 1 mucosal swelling, and 1 mucosal wrinkle change. The sensitivity and specificity of capsule endoscopy in the diagnosis of upper gastrointestinal bleeding were 92.31% (12/13) and 75.00% (3/4) respectively. The sensitivity and specificity of capsule endoscopy for diagnosing small intestinal bleeding were 80.49% (33/41) and 90.91% (10/11) respectively.Conclusion:Bedside capsule endoscopy demonstrates high sensitivity and specificity in the diagnosis of gastrointestinal bleeding, showing potential advantages in bedside applications for acute and severe gastrointestinal bleeding.
